Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the DF7C-3P-3.96DSA(25) is determined by the following critical parameters:

• Pitch - Mating: 0.156" (3.96mm) — must match exactly for mechanical and electrical alignment
• Number of Positions: 3 — connector must accommodate the same pin count
• Connector Type: Header — must be a header configuration for board-to-cable/wire connection
• Mounting Type: Through Hole — must support through-hole PCB mounting
• Shrouding: Shrouded - 4 Wall — must provide equivalent mechanical protection and keying
• Termination: Solder — must support solder termination for PCB assembly
• Material Flammability Rating: UL94 V-0 — must meet or exceed flame resistance requirements

The substitute part 179839-1 (TE Connectivity AMP Connectors) satisfies all critical substitution parameters while maintaining functional equivalence in board-to-cable/wire applications.

Parameter Comparison

Engineering Selection Recommendations

The DF7C-3P-3.96DSA(25) is classified as obsolete. The substitute part 179839-1 is active and available in production quantities (3607 pcs in stock versus 1157 pcs for the original part).

Both parts meet UL94 V-0 flammability requirements and share identical pitch, position count, shrouding configuration, and termination method. The substitute part operates across a wider temperature range (-30°C ~ 105°C versus -35°C ~ 85°C), providing enhanced thermal performance for extended operating conditions.

The 179839-1 features a kinked pin termination in addition to solder capability, offering improved mechanical retention during PCB assembly. Both parts carry MSL 1 (Unlimited) moisture sensitivity classification and share identical ECCN and HTSUS codes, indicating equivalent regulatory and trade classification status.

Frequently Asked Questions (FAQ)

Q: Can 179839-1 directly replace DF7C-3P-3.96DSA(25) in existing designs?

A: Yes. Both connectors share identical pitch (0.156" / 3.96mm), position count (3), shrouding configuration (4-wall), and termination method (solder). The mechanical and electrical interfaces are compatible for board-to-cable/wire applications.

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

A: The primary differences are contact shape (square versus rectangular), insulation height (0.508" versus 0.575"), contact post length (0.138" versus 0.150"), and operating temperature range. The substitute part supports a wider temperature range (-30°C ~ 105°C) and includes kinked pin termination for enhanced mechanical retention.

Q: Are there packaging differences between the original and substitute part?

A: The original part has no specified packaging designation. The substitute part 179839-1 is supplied in Tray packaging. Verify tray compatibility with your assembly process requirements.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are classified as UL94 V-0 for material flammability, carry MSL 1 (Unlimited) moisture sensitivity, and share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Q: What is the availability status of each part?

A: The DF7C-3P-3.96DSA(25) is obsolete with limited inventory (1157 pcs). The substitute 179839-1 is active with higher availability (3607 pcs in stock).
