DF1B-10P-2.5DSA Equivalent & Substitute Parts

Part Overview

The DF1B-10P-2.5DSA is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for through-hole mounting in board-to-cable/wire applications. This 10-position connector operates at 250V with a 2.5mm pitch and features shrouded 4-wall construction with push-pull fastening. The main part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF1B-10P-2.5DSA is determined by the following critical parameters: connector type (header), contact type (male pin), number of positions (10), mating pitch (2.5mm), mounting method (through hole), shrouding configuration (shrouded 4-wall), fastening mechanism (push-pull), voltage rating (250V), and operating temperature range (-35°C ~ 85°C). All substitute parts must maintain identical values across these parameters to ensure mechanical and electrical compatibility with existing PCB designs and mating connectors.

The identified substitutes are:

• DF1BZ-10P-2.5DSA (direct manufacturer equivalent, active status)
• DF1B-10P-2.5DSA(01) (manufacturer-recommended variant, active status)

Parameter Comparison

Engineering Selection Recommendations

For new designs and production requiring RoHS3 compliance, both DF1BZ-10P-2.5DSA and DF1B-10P-2.5DSA(01) are suitable active alternatives to the obsolete DF1B-10P-2.5DSA. The DF1BZ-10P-2.5DSA maintains tin contact finish matching the original specification, while DF1B-10P-2.5DSA(01) provides gold contact finish. Both substitutes are manufactured by Hirose Electric Co Ltd and maintain identical mechanical and electrical parameters. Selection between these two should be based on contact finish requirements for your specific application and mating connector specifications.

Frequently Asked Questions (FAQ)

Q: Can DF1BZ-10P-2.5DSA be used as a direct replacement for DF1B-10P-2.5DSA?

A: Yes. Both connectors share identical mechanical dimensions, pitch, number of positions, mounting type, and electrical ratings. The primary difference is product status (active vs. obsolete) and RoHS compliance. The tin contact finish of DF1BZ-10P-2.5DSA matches the original specification.

Q: What is the difference between DF1BZ-10P-2.5DSA and DF1B-10P-2.5DSA(01)?

A: Both are active Hirose products with identical mechanical and electrical specifications. The key difference is contact finish: DF1BZ-10P-2.5DSA uses tin finish, while DF1B-10P-2.5DSA(01) uses gold finish. Contact finish selection depends on your mating connector and application requirements.

Q: Are these substitutes compatible with existing PCB designs?

A: Yes. All three connectors maintain identical pitch (2.5mm), number of positions (10), mounting type (through hole), and overall dimensions. They are mechanically and electrically interchangeable on PCBs designed for the DF1B-10P-2.5DSA.

Q: Do the substitute parts meet current compliance standards?

A: Both DF1BZ-10P-2.5DSA and DF1B-10P-2.5DSA(01) are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The original DF1B-10P-2.5DSA is RoHS non-compliant.

Q: What packaging is available for these connectors?

A: DF1BZ-10P-2.5DSA and DF1B-10P-2.5DSA(01) are supplied in bulk packaging, with current inventory availability of 862 and 839 units respectively.
