Substitute Part Grouping Explanation

The DF3A-6P-2DSA serves as the direct active equivalent to the obsolete DF3A-6P-2DSA(10). Substitution is valid based on identical electrical and mechanical parameters: both parts maintain the same 6-position configuration at 2.00mm pitch, identical contact specifications (male pin, square shape, tin finish on brass material), matching mounting methodology (through-hole, press-fit/solder termination), and equivalent performance ratings (3A current, -55°C to 105°C operating range, UL94 V-0 flammability rating).

The critical parameters determining substitution validity are:

Number of positions: 6
Pitch spacing: 0.079" (2.00mm)
Contact type: Male pin
Mounting type: Through hole
Shrouding configuration: Shrouded - 4 wall
Current rating: 3A
Operating temperature range: -55°C ~ 105°C

Engineering Selection Recommendations

The DF3A-6P-2DSA is the direct active substitute for the obsolete DF3A-6P-2DSA(10). Both parts are manufactured by Hirose Electric Co Ltd and maintain identical electrical and mechanical specifications across all critical parameters. The active part carries ROHS3 compliance status compared to RoHS compliance on the obsolete variant, representing an advancement in regulatory alignment. Both parts maintain MSL 1 (Unlimited) moisture sensitivity rating and identical ECCN/HTSUS classifications. The only non-functional difference is insulation color (white versus black) and packaging format (bulk for the active part). For new designs or ongoing production requiring this connector type, the DF3A-6P-2DSA should be specified.

Frequently Asked Questions (FAQ)

Q: Can DF3A-6P-2DSA be used as a direct replacement for DF3A-6P-2DSA(10)?

A: Yes. Both parts are electrically and mechanically identical across all functional parameters including position count, pitch spacing, contact specifications, current rating, and operating temperature range. The active part DF3A-6P-2DSA is the current production equivalent.

Q: What is the difference between the two part numbers?

A: The primary difference is product status: DF3A-6P-2DSA(10) is obsolete while DF3A-6P-2DSA is active production. The active part carries ROHS3 compliance versus RoHS compliance on the obsolete variant. Insulation color differs (white versus black), and packaging is specified as bulk for the active part. All electrical and mechanical performance parameters remain identical.

Q: Are there any compatibility concerns when substituting these parts?

A: No compatibility concerns exist. The parts are functionally equivalent with identical mating interfaces, contact configurations, and mounting specifications. PCB footprints and mating connector requirements remain unchanged.

Q: What is the current inventory status?

A: The obsolete DF3A-6P-2DSA(10) has 1086 pieces in stock. The active DF3A-6P-2DSA has 1590 pieces in stock.

Q: Does the insulation color change affect functionality?

A: No. Insulation color is a cosmetic parameter and does not affect electrical performance, mechanical fit, or operational characteristics.

Q: What compliance certifications apply to the substitute part?

A: The DF3A-6P-2DSA carries ROHS3 compliance, UL94 V-0 flammability rating, MSL 1 (Unlimited) moisture sensitivity level, and REACH Unaffected status. ECCN and HTSUS classifications remain identical to the obsolete part.
