Substitute Part Grouping Explanation

Substitution eligibility for the DF1B-10DP-2.5DS is determined by the following critical parameters:

Connector type, contact type, and fastening mechanism (Header, Male Pin, Push-Pull)
Physical dimensions: 10 positions, 2 rows, 0.098" (2.50mm) pitch and row spacing
Mounting configuration: Through hole, right-angle orientation
Shrouding design: Shrouded with 4-wall construction
Electrical ratings: Operating temperature range and voltage rating
Termination method: Solder
Material compliance: UL94 V-0 flammability rating

Two substitute parts meet these criteria within the DF1B series:

DF1BZ-10DP-2.5DS - Direct manufacturer equivalent with active product status and RoHS3 compliance
DF1B-10DP-2.5DS(01) - Manufacturer-recommended successor with active product status, RoHS3 compliance, and gold contact finish

Engineering Selection Recommendations

DF1B-10DP-2.5DS(01) is the manufacturer-recommended successor for the obsolete DF1B-10DP-2.5DS. This part maintains identical mechanical and electrical specifications including the 250V voltage rating, operating temperature range, and UL94 V-0 flammability rating. The primary differences are active product status, RoHS3 compliance, and gold contact finish on the mating surface. Gold plating provides enhanced corrosion resistance compared to tin finish.

DF1BZ-10DP-2.5DS is an alternative direct equivalent within the DF1B series with active product status and RoHS3 compliance. This part shares all mechanical specifications and operating temperature range. The voltage rating is specified as 150V, which is lower than the original 250V rating. Selection of this part requires confirmation that the 150V rating is acceptable for the application.

For new designs and procurement of replacement units, DF1B-10DP-2.5DS(01) is the primary recommendation due to manufacturer endorsement and full electrical specification alignment with the original part.

Frequently Asked Questions (FAQ)

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

A: DF1BZ-10DP-2.5DS shares all mechanical specifications and mounting characteristics. The voltage rating differs: DF1BZ-10DP-2.5DS is rated at 150V versus 250V for the original part. Substitution is valid only if the application operates at or below 150V.

Q: What is the difference between DF1B-10DP-2.5DS(01) and the original DF1B-10DP-2.5DS?

A: Both parts maintain identical mechanical dimensions, pitch spacing, mounting type, and operating temperature range. DF1B-10DP-2.5DS(01) features gold contact finish on the mating surface instead of tin, has active product status, and is RoHS3 compliant. Voltage rating remains 250V for both parts.

Q: Why is the original DF1B-10DP-2.5DS marked as obsolete?

A: Product obsolescence indicates the part is no longer in active production. DF1B-10DP-2.5DS(01) has been designated as the active successor within the DF1B series.

Q: Are there packaging differences between these parts?

A: The original DF1B-10DP-2.5DS packaging is not specified. DF1BZ-10DP-2.5DS and DF1B-10DP-2.5DS(01) are supplied in bulk packaging.

Q: Do all three parts have the same contact material and insulation specifications?

A: Yes. All three parts use brass contact material with polyamide (PA) nylon insulation, keying slot features, and white insulation color. All meet UL94 V-0 flammability requirements and have unlimited moisture sensitivity level (MSL 1).

Q: Which part should be selected for new PCB designs?

A: DF1B-10DP-2.5DS(01) is the manufacturer-recommended choice for new designs, offering active product status, RoHS3 compliance, and full electrical specification alignment with the original part.
