NABCO SMD-101-01 PCB Card

Description

Product Introduction & Engineering Value

The NABCO SMD-101-01 is a legacy marine PCB card that should be treated as a system-specific spare, not a generic circuit board. Current marine spare listings identify it with 822 73744895 and show it as part of an SMD-series PCB assembly associated with SMD-102-01.

For procurement and maintenance teams, the key point is identification accuracy. The related SMD-102-01 carries a different part number, 822 73744896. That one-digit difference is enough to warrant a full compatibility check before substitution.

Technical Specifications

The available listing identifies the SMD-101-01/SMD-102-01 combination as a new PCB card, with the SMD-101-01 carrying 822 73744895 and SMD-102-01 carrying 822 73744896.

Electrical ratings: Reliable public sources located for this model do not provide verified input voltage, output voltage, I/O count, or communication specifications. Those values should not be inferred.

Field Application & the “Trench” Experience

A vessel maintenance team replacing an obsolete NABCO control assembly can easily encounter several SMD-series cards that look related. During a scheduled overhaul, the technician finds an SMD-101-01 installed beside an SMD-102-01 and discovers that both boards must be identified independently.

The correct procedure is simple but important: photograph the original cards, record the complete part numbers, compare the PCB markings, and match the replacement against the equipment documentation. For the SMD-101-01, the primary procurement reference is 822 73744895, with K27050 providing an additional board-level identification point.

Typical application scenarios include:

• Legacy NABCO marine control cabinet refurbishment
• Shipboard automation PCB replacement during scheduled overhaul
• Critical spare inventory for long-service marine control systems

Transparency SOP: QA & Testing

For this PCB, traceable identification should precede electrical testing.

1. Identity verification

• Confirm NABCO .
• Verify 822 73744895.
• Check PCB marking K27050.
• Record any additional labels or revision information.

2. Physical inspection

• Examine PCB traces and solder joints.
• Inspect connectors and contacts.
• Check for corrosion, contamination, or mechanical damage.

3. Electrical testing

• Perform applicable continuity and resistance checks.
• Verify supply circuits against the original equipment documentation.
• Do not borrow electrical specifications from or another NABCO card.

4. Functional verification

• Use an appropriate test fixture where available.
• Confirm system-level operation after installation.
• Record test results with the spare inventory record.

The current supplier data reviewed lists / stock as new. That is a supplier condition designation and should not be confused with a current OEM warranty or certification.

The Veteran’s Tech Trap Guide

⚠️ Do not confuse with .
They are separately identified boards. is listed as 822 73744895, while is 822 73744896.

⚠️ Use the part number as the primary purchasing reference.
The complete combination of model + part number + PCB marking is much safer than searching by the SMD family alone.

⚠️ PRO TIP: Keep the removed board until commissioning is complete.
The original card provides a valuable reference for connector orientation, revision markings, and physical configuration.

⚠️ Do not invent electrical specifications.
Public listings identify the board but do not establish its detailed electrical ratings. Use the original NABCO schematic or equipment manual for those values.

Dynamic FAQ

Q1. What is the NABCO ?

The NABCO is a PCB card used in legacy marine/industrial control equipment. It is listed with NABCO part number 822 73744895.

Q2. What is the part number for ?

The listed NABCO part number is 822 73744895.

Q3. What is K27050?

K27050 is identified as the PCB marking associated with the / card assembly in current supplier documentation.

Q4. Is interchangeable with ?

Do not assume interchangeability. They have different model designations and different NABCO part numbers. Verify the equipment documentation before substitution.

Q5. Is New Surplus available?

Current supplier listings show the / assembly as new stock. Actual availability and condition should be confirmed for the specific unit being quoted.

Q6. How should buyers verify authenticity?

Request photographs of the actual board showing , 822 73744895, K27050, connectors, and any original packaging or labels. Do not rely solely on a catalog photograph.

Q7. What warranty should buyers expect?

Warranty is supplier-specific. The available listing identifies the board as new but does not establish an OEM NABCO warranty. The quotation should clearly state the seller’s warranty and return terms.
