Substitute Part Grouping Explanation

Substitution for the DF1B-7P-2.5DSA is determined by strict equivalence across the following parameters:

  • Connector type (Header)
  • Number of positions (7)
  • Pitch specification (0.098" / 2.50mm)
  • Mounting method (Through Hole)
  • Shrouding configuration (Shrouded - 4 Wall)
  • Fastening type (Push-Pull)
  • Voltage rating (250V)
  • Operating temperature range (-35°C ~ 85°C)
  • Insulation material (Polyamide/Nylon)
  • Mated stacking height (14mm)

The identified substitutes maintain all critical electrical and mechanical parameters. Variations in contact finish and product status are noted but do not affect functional compatibility in standard applications.

Engineering Selection Recommendations

Both DF1BZ-7P-2.5DSA and DF1B-7P-2.5DSA(01) are active product alternatives to the obsolete DF1B-7P-2.5DSA. Selection between these substitutes depends on regulatory and compliance requirements:

DF1BZ-7P-2.5DSA is ROHS3 compliant with tin contact finish and bulk packaging. This option is suitable for applications requiring RoHS compliance with standard tin-plated contacts.

DF1B-7P-2.5DSA(01) is ROHS3 compliant with gold contact finish and bulk packaging. This option provides enhanced contact reliability through gold plating and is suitable for applications requiring RoHS compliance with superior contact performance.

Both substitutes maintain identical electrical ratings, mechanical dimensions, and thermal specifications as the original part. The choice between them is determined by contact finish requirements and application-specific reliability criteria.

Frequently Asked Questions (FAQ)

Q: Can DF1BZ-7P-2.5DSA directly replace DF1B-7P-2.5DSA?

A: Yes. Both parts share identical connector type, position count, pitch, mounting method, shrouding, fastening mechanism, voltage rating, and operating temperature range. The primary difference is product status (active vs. obsolete) and RoHS compliance.

Q: What is the difference between DF1BZ-7P-2.5DSA and DF1B-7P-2.5DSA(01)?

A: Both are active ROHS3-compliant alternatives. The key distinction is contact finish: DF1BZ-7P-2.5DSA uses tin plating, while DF1B-7P-2.5DSA(01) uses gold plating. Contact finish selection depends on application requirements for contact durability and signal integrity.

Q: Are there packaging differences between the substitutes?

A: Both substitute parts are supplied in bulk packaging, differing from the original part's unspecified packaging. Bulk packaging is standard for these connector series.

Q: Do the substitutes maintain the same mechanical fit?

A: Yes. All three parts share identical overall contact length (0.417" / 10.60mm), insulation height (0.374" / 9.50mm), and mated stacking height (14mm). Mechanical compatibility is maintained.

Q: Is RoHS compliance a factor in selecting a substitute?

A: The original DF1B-7P-2.5DSA is RoHS non-compliant. Both substitutes are ROHS3 compliant. Applications subject to RoHS regulations must use one of the compliant alternatives.
