Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the DF7C-2P-3.96DSA(25) is determined by the following critical parameters:

• Connector pitch: 0.156" (3.96mm) mating pitch
• Position count: 2 positions
• Mounting configuration: Through-hole, board-to-cable/wire style
• Shrouding design: Shrouded 4-wall construction
• Termination method: Solder-compatible termination
• Mechanical interface: Latch/fastening compatibility with mating connectors

The substitute part 179838-1 (TE Connectivity AMP Connectors) meets these core substitution criteria through matching pitch, position count, mounting type, shrouding configuration, and solder termination capability.

Parameter Comparison

Engineering Selection Recommendations

The DF7C-2P-3.96DSA(25) is classified as obsolete. The substitute part 179838-1 is active and available in production quantities (2040 pcs in stock versus 952 pcs for the original part).

Both parts carry UL94 V-0 flammability certification and share identical ECCN and HTSUS classifications, confirming regulatory equivalence. The substitute part operates across a wider temperature range (-30°C ~ 105°C versus -35°C ~ 85°C), providing extended thermal capability.

The 179838-1 features a kinked pin termination option in addition to solder termination, offering enhanced mechanical retention during assembly. Both parts maintain identical moisture sensitivity levels and contact material specifications.

Frequently Asked Questions (FAQ)

Q: Can 179838-1 directly replace DF7C-2P-3.96DSA(25) in existing designs?

A: Yes. Both connectors share the same 0.156" (3.96mm) pitch, 2-position configuration, through-hole mounting, shrouded 4-wall design, and solder termination. Mechanical and electrical interfaces are compatible.

Q: What are the key differences between these two parts?

A: The primary differences are contact shape (square versus rectangular), insulation height (0.508" versus 0.575"), fastening mechanism (latch holder versus locking ramp), and operating temperature range. The substitute part supports a wider temperature range and includes kinked pin termination as an option.

Q: Are there compliance or certification concerns with substitution?

A: No. Both parts carry UL94 V-0 flammability ratings, share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, and maintain MSL 1 moisture sensitivity levels.

Q: What is the packaging difference?

A: The original part packaging is not specified in available data. The substitute part 179838-1 is supplied in tray packaging.

Q: Does the wider operating temperature range of 179838-1 affect compatibility?

A: No. The substitute part's extended temperature capability (-30°C ~ 105°C) encompasses the original part's operating range (-35°C ~ 85°C), ensuring thermal compatibility in all applications where the original part was used.
