Engineering Selection Recommendations

The DF1B-22DP-2.5DSA is obsolete and no longer in active production. Two active alternatives are available:

DF1BZ-22DP-2.5DSA is a direct substitute with identical electrical and mechanical specifications. This part is RoHS compliant and available in tray packaging. The DF1BZ variant designation indicates RoHS compliance while maintaining full functional equivalence to the original part.

DF1B-22DP-2.5DSA(01) is the manufacturer-recommended replacement, also RoHS compliant and available in bulk packaging. This part differs only in contact finish specification, featuring gold plating on mating contacts instead of tin. Gold plating provides enhanced corrosion resistance and is suitable for applications requiring superior contact reliability over extended service life.

Both substitutes maintain identical mechanical dimensions, electrical ratings, and thermal operating ranges. Selection between them depends on packaging requirements and contact finish specifications for the application.

Frequently Asked Questions (FAQ)

Q: Can DF1BZ-22DP-2.5DSA be used as a direct replacement for DF1B-22DP-2.5DSA?

A: Yes. Both parts share identical electrical and mechanical specifications across all critical parameters including position count, pitch spacing, contact geometry, operating temperature range, and voltage rating. The DF1BZ variant is the RoHS-compliant equivalent of the original part.

Q: What is the difference between DF1BZ-22DP-2.5DSA and DF1B-22DP-2.5DSA(01)?

A: Both are functionally equivalent substitutes. The primary difference is contact finish: DF1BZ-22DP-2.5DSA uses tin plating on mating contacts, while DF1B-22DP-2.5DSA(01) uses gold plating. Gold-plated contacts offer improved corrosion resistance. Packaging also differs: DF1BZ is supplied in tray format, while DF1B-22DP-2.5DSA(01) is supplied in bulk.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both DF1BZ-22DP-2.5DSA and DF1B-22DP-2.5DSA(01) are RoHS compliant. The original DF1B-22DP-2.5DSA is RoHS non-compliant.

Q: Do the substitute parts maintain the same physical dimensions and mounting footprint?

A: Yes. All three parts share identical mechanical dimensions including contact length, insulation height, overall contact length, and mated stacking height of 14mm. Through-hole mounting footprint is identical.

Q: What packaging options are available for the substitute parts?

A: DF1BZ-22DP-2.5DSA is available in tray packaging. DF1B-22DP-2.5DSA(01) is available in bulk packaging. Packaging selection should align with procurement and assembly workflow requirements.
