Substitute Part Grouping Explanation

Substitution eligibility for the DF1B-14P-2.5DSA is determined by the following critical parameters:

Connector type, contact type, and gender (Header, Male Pin)
Number of positions and mating pitch (14 positions, 0.098" / 2.50mm)
Mounting method and termination (Through Hole, Solder)
Shrouding configuration (Shrouded - 4 Wall)
Fastening mechanism (Push-Pull)
Operating temperature range (-35°C ~ 85°C)
Voltage rating (250V)
Flammability rating (UL94 V-0)

The identified substitutes maintain all critical electrical and mechanical parameters. Variations in contact finish material and RoHS compliance status do not affect functional interchangeability in the connector interface.

Engineering Selection Recommendations

Both substitute parts maintain full functional and mechanical compatibility with the DF1B-14P-2.5DSA. Selection between alternatives should be based on product status and regulatory compliance requirements.

DF1BZ-14P-2.5DSA is an active product with RoHS compliance status, offering improved supply chain availability compared to the obsolete main part. This variant features tin contact finish matching the original specification.

DF1B-14P-2.5DSA(01) is the manufacturer-recommended substitute, designated as active with RoHS compliance. This variant incorporates gold contact finish, which differs from the original tin finish but maintains electrical compatibility and provides enhanced contact durability characteristics.

For new designs and ongoing procurement, either active substitute is suitable. Selection should align with specific regulatory requirements, supply chain preferences, and contact finish specifications for the application.

Frequently Asked Questions (FAQ)

Q: Are the substitute parts electrically and mechanically interchangeable with the DF1B-14P-2.5DSA?

A: Yes. Both substitute parts maintain identical electrical ratings (250V), mechanical dimensions, pitch spacing (2.50mm), number of positions (14), mounting method (through-hole solder), and operating temperature range (-35°C ~ 85°C). All critical interface parameters are preserved.

Q: What is the difference between DF1BZ-14P-2.5DSA and DF1B-14P-2.5DSA(01)?

A: The primary difference is contact finish material. DF1BZ-14P-2.5DSA uses tin finish, matching the original part. DF1B-14P-2.5DSA(01) uses gold finish. Both are RoHS compliant and active products. Contact finish selection depends on application requirements and environmental exposure conditions.

Q: Why is the original DF1B-14P-2.5DSA marked as obsolete?

A: Obsolescence indicates the part is no longer in active production. The identified substitutes are active products from the same manufacturer and series, providing direct functional replacement with improved supply availability.

Q: Does RoHS compliance status affect connector functionality?

A: RoHS compliance indicates conformance to material restrictions on hazardous substances. Both substitute parts are RoHS compliant, while the original is non-compliant. This affects regulatory acceptance in specific markets and applications but does not alter electrical or mechanical performance.

Q: Are packaging differences significant for component selection?

A: Packaging format (bulk vs. other configurations) affects procurement and handling but does not impact connector performance or compatibility. Selection should align with manufacturing process requirements and inventory management practices.
