Engineering Selection Recommendations

Primary Substitute: TE Connectivity 174469-3

The 174469-3 is the direct functional equivalent for the obsolete 737426-2. Selection of this substitute is based on the following engineering criteria:

Compliance and Certification:

• Both parts maintain RoHS compliance, with 174469-3 holding active RoHS certification status
• Both parts carry MSL Level 1 (Unlimited) moisture sensitivity rating
• Both parts are classified under identical ECCN (EAR99) and HTSUS (8538.90.8180) codes

Product Status:

• The 174469-3 maintains active product status with current manufacturing support
• The 737426-2 is obsolete and subject to supply discontinuation

Mechanical and Electrical Equivalence:

• All critical parameters for D-Sub backshell functionality are identical
• Shell size, position count, cable exit angle, and connector compatibility are fully matched
• Material composition and hardware specifications are equivalent

Cosmetic and Finish Variations:

• Color difference (Black to Silver) and nickel plating on 174469-3 do not affect electrical or mechanical performance
• These variations are allowable substitutions within D-Sub connector accessory standards

Frequently Asked Questions (FAQ)

Q: Can the 174469-3 be used as a direct replacement for the 737426-2 in existing assemblies?

A: Yes. The 174469-3 maintains identical mechanical and electrical specifications across all critical parameters including position count, shell size, cable exit angle, and connector compatibility. The color and plating differences do not affect functional performance.

Q: What is the significance of the color difference between the two parts?

A: The color difference (Black versus Silver) is a cosmetic variation that does not impact electrical or mechanical function. Both parts are constructed from identical ABS material and perform the same backshell function. Color selection is determined by application requirements or assembly aesthetics.

Q: Does the nickel plating on the 174469-3 affect compatibility?

A: No. The nickel plating on the 174469-3 is an allowable variation that enhances corrosion resistance without affecting mechanical fit or electrical performance. The plating is applied to the external hardware and does not alter the backshell's interface with the D-Sub connector.

Q: Are both parts RoHS compliant?

A: Yes. The 737426-2 is ROHS3 Compliant, and the 174469-3 is RoHS Compliant. Both parts meet regulatory requirements for hazardous substance restrictions.

Q: What is the difference between the AMPLIMITE and AMPLIMITE HD-20 series designations?

A: Both designations refer to TE Connectivity's AMPLIMITE connector series. The HD-20 designation on the 174469-3 indicates an updated product line within the same series family. The parts maintain full compatibility and interchangeability.

Q: Is the 174469-3 available in the same packaging as the 737426-2?

A: The 174469-3 is supplied in Box packaging. Packaging format does not affect the component's functional or mechanical compatibility with D-Sub connector assemblies.

Q: Why is the 737426-2 listed as obsolete?

A: Obsolete status indicates that the manufacturer has discontinued active production and support for this part number. The 174469-3 serves as the active equivalent and is recommended for new designs and ongoing production requirements.

Q: Can both parts be used interchangeably in the same connector assembly?

A: Yes. Both parts are mechanically and electrically equivalent for D-Sub backshell applications. They share identical position counts, shell sizes, cable exit angles, and connector compatibility specifications.
