Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 171-025-102-021 is determined by strict alignment with the following core electrical and mechanical parameters:

• Connector Type: Plug with male pins (ensures mating compatibility with socket receptacles)
• Number of Positions: 25 positions (maintains signal channel count and pin layout)
• Number of Rows: 2 rows (preserves physical arrangement and contact spacing)
• Mounting Type: Panel mount (ensures installation compatibility with existing mechanical designs)
• Shell Size and Layout: Size 3 (DB, B) configuration (guarantees dimensional and contact alignment)
• Manufacturer Series: 171 family (confirms design lineage and standardized specifications)

The substitute part 171-025-103L021 meets all these criteria, establishing it as a direct functional equivalent within the NorComp Inc. product portfolio.

Parameter Comparison

Engineering Selection Recommendations

Both the 171-025-102-021 and 171-025-103L021 are active product status components manufactured by NorComp Inc. within the Series 171 family. Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component procurement.

The 171-025-102-021 is currently available with higher inventory levels (1097 units), making it the preferred selection for immediate procurement needs. The 171-025-103L021 serves as a viable alternative with 951 units in stock, offering equivalent electrical and mechanical performance.

Selection between these parts should be based on availability requirements and supply chain scheduling. Both parts satisfy identical functional specifications for 25-position D-Sub plug applications with panel mount configuration, signal contact type, and solder cup termination.

Frequently Asked Questions (FAQ)

Q: Are the 171-025-102-021 and 171-025-103L021 electrically interchangeable?

A: Yes. Both connectors are 25-position D-Sub plugs with identical electrical ratings (5A current, signal contact type), operating temperature range (-50°C to 100°C), and contact finish specifications (gold flash). They are direct functional equivalents.

Q: What determines substitution compatibility for these D-Sub connectors?

A: Substitution is valid when the following parameters match: connector type (plug with male pins), number of positions (25), number of rows (2), mounting type (panel mount), shell size and layout (Size 3, DB/B configuration), and series designation (171). All these parameters are identical between the main part and substitute.

Q: Do packaging differences affect mechanical compatibility?

A: No. The 171-025-102-021 is supplied without specified packaging, while the 171-025-103L021 is packaged in trays. Packaging affects logistics and storage only; it does not impact connector form, fit, or function in the application.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the 171-025-102-021 and 171-025-103L021 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component use.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection should be based on current inventory availability and supply chain lead times. Both parts carry active product status and identical technical specifications.
