Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF7-2P-3.96DSA(26) is determined by the following critical parameters:

• Connector pitch: 0.156" (3.96mm) mating pitch is the primary compatibility criterion
• Number of positions: 2-position configuration must be maintained
• Mounting method: Through-hole mounting requirement
• Shrouding configuration: 4-wall shrouded design
• Termination type: Solder termination capability
• Connector style: Board-to-cable/wire application interface
• Material compliance: UL94 V-0 flammability rating

The substitute part 179838-1 (TE Connectivity AMP Connectors) meets these core electrical and mechanical parameters, enabling functional equivalence in the specified application.

Parameter Comparison

Engineering Selection Recommendations

The DF7-2P-3.96DSA(26) is classified as obsolete. The substitute part 179838-1 is currently active in production and available through standard distribution channels.

Both parts satisfy the core electrical and mechanical requirements for 2-position, 0.156" pitch rectangular connector applications with through-hole solder termination and 4-wall shrouding. Both components carry UL94 V-0 flammability certification and unlimited moisture sensitivity classification.

The substitute part 179838-1 operates across a wider temperature range (-30°C ~ 105°C versus -35°C ~ 85°C) and carries RoHS3 compliance status, providing enhanced regulatory alignment for new designs and ongoing procurement.

Frequently Asked Questions (FAQ)

Q: Can 179838-1 be used as a direct replacement for DF7-2P-3.96DSA(26)?

A: Yes. Both connectors share identical mating pitch (0.156"), position count (2), mounting method (through-hole), shrouding configuration (4-wall), and termination capability (solder). Both meet UL94 V-0 flammability requirements.

Q: What are the key differences between these parts?

A: The primary differences are contact finish (gold versus tin), contact shape (square versus rectangular), insulation material composition (glass-filled PA versus PA66), and operating temperature range. The substitute part operates to 105°C versus 85°C maximum.

Q: Are there packaging differences?

A: The DF7-2P-3.96DSA(26) packaging is not specified in available data. The 179838-1 is supplied in tray packaging.

Q: Does the insulation color difference affect compatibility?

A: No. Insulation color is a visual identifier only and does not affect electrical or mechanical compatibility in the specified application.

Q: What is the significance of the contact finish difference?

A: Both gold and tin finishes provide adequate corrosion resistance for solder termination applications. The tin finish on 179838-1 is suitable for the same board-to-cable/wire interface as the gold-finished original part.
