Substitute Part Grouping Explanation

Substitution for the DF1B-12DP-2.5DSA is determined by strict equivalence across the following critical parameters:

Connector type (Header)
Contact type (Male Pin)
Number of positions (12) and row configuration (2 rows)
Pitch specifications (0.098" / 2.50mm mating pitch and row spacing)
Mounting method (Through Hole)
Shrouding design (Shrouded - 4 Wall)
Fastening mechanism (Push-Pull)
Termination method (Solder)
Voltage rating (250V)
Operating temperature range (-35°C ~ 85°C)
Flammability rating (UL94 V-0)

The substitute parts identified maintain identical electrical and mechanical specifications across these parameters. Variations in product status, packaging, contact finish, and compliance certifications do not affect functional interchangeability in the connector interface.

Engineering Selection Recommendations

Both DF1BZ-12DP-2.5DSA and DF1B-12DP-2.5DSA(01) are functionally equivalent substitutes for the obsolete DF1B-12DP-2.5DSA based on identical electrical and mechanical specifications.

DF1BZ-12DP-2.5DSA is the direct manufacturer substitute with active product status and ROHS3 compliance. This part maintains tin contact finish matching the original specification and is available in tray packaging.

DF1B-12DP-2.5DSA(01) is the manufacturer-recommended alternative with active product status and ROHS3 compliance. This part features gold contact finish on the mating surface and is available in bulk packaging. The gold finish provides enhanced corrosion resistance compared to tin plating.

Both substitutes are ROHS3 compliant, addressing regulatory requirements that the original part does not meet. Selection between these two substitutes depends on packaging requirements and contact finish specifications for the application.

Frequently Asked Questions (FAQ)

Q: Can DF1BZ-12DP-2.5DSA and DF1B-12DP-2.5DSA(01) be used interchangeably with the original DF1B-12DP-2.5DSA?

A: Yes. Both substitutes maintain identical connector type, position count, pitch, mounting method, shrouding, fastening mechanism, and electrical ratings. The connectors are mechanically and electrically interchangeable in the mating interface.

Q: What is the difference between the two substitute parts?

A: The primary differences are contact finish (tin versus gold), packaging format (tray versus bulk), and inventory availability. Both parts are functionally equivalent for connector interface applications.

Q: Does the gold contact finish on DF1B-12DP-2.5DSA(01) affect compatibility?

A: No. Gold plating on the mating contact surface does not affect mechanical or electrical compatibility. Gold finish provides enhanced corrosion resistance and is compatible with standard tin-plated mating connectors.

Q: Are both substitutes RoHS compliant?

A: Yes. Both DF1BZ-12DP-2.5DSA and DF1B-12DP-2.5DSA(01) are ROHS3 compliant. The original DF1B-12DP-2.5DSA is RoHS non-compliant.

Q: What packaging options are available for these substitutes?

A: DF1BZ-12DP-2.5DSA is supplied in tray packaging. DF1B-12DP-2.5DSA(01) is supplied in bulk packaging. Packaging selection depends on assembly process requirements and handling procedures.

Q: Do the substitutes maintain the same operating temperature range?

A: Yes. Both substitutes operate across the identical temperature range of -35°C to 85°C.
