Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF7C-4P-3.96DSA(25) is determined by the following critical parameters:

• Pitch - Mating: 0.156" (3.96mm) — must match exactly for mechanical and electrical compatibility
• Number of Positions: 4 — connector capacity requirement
• Connector Type: Header — functional role in board-to-cable/wire applications
• Mounting Type: Through Hole — PCB assembly method
• Shrouding: Shrouded - 4 Wall — mechanical protection and alignment
• Material Flammability Rating: UL94 V-0 — safety compliance requirement

The substitute part 179840-1 (TE Connectivity AMP Connectors) satisfies these core parameters while offering active product status and enhanced operating temperature range. Differences in contact type (Tab vs. Male Pin), row configuration (2 rows vs. 1 row), and fastening mechanism (Locking Ramp vs. Latch Holder) represent design variations that do not preclude functional substitution when mating interface compatibility is confirmed.

Parameter Comparison

Engineering Selection Recommendations

The DF7C-4P-3.96DSA(25) is classified as obsolete, necessitating transition to active alternatives for new procurement and long-term system support. The substitute part 179840-1 from TE Connectivity AMP Connectors is an active product that maintains compliance with UL94 V-0 flammability requirements and REACH regulations.

Key advantages of 179840-1 include extended operating temperature range (-30°C ~ 105°C versus -35°C ~ 85°C) and active product status ensuring continued availability and supply chain stability. Both components share identical mating pitch, position count, shrouding configuration, and contact finish specifications, supporting direct functional replacement in board-to-cable/wire applications.

The substitute part features a two-row configuration and locking ramp fastening mechanism, which represent design enhancements over the original single-row latch holder design. Confirmation of mating interface compatibility with existing cable assemblies or receptacle connectors is required prior to implementation.

Frequently Asked Questions (FAQ)

Q: Can 179840-1 directly replace DF7C-4P-3.96DSA(25) in existing designs?

A: Both connectors share the same 0.156" (3.96mm) mating pitch, 4-position capacity, through-hole mounting, and shrouded 4-wall configuration. Direct replacement is feasible when the mating receptacle or cable assembly connector is compatible with the 179840-1 contact interface. Physical fit and electrical continuity must be confirmed for the specific application.

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

A: The primary differences are contact type (Male Pin vs. Tab), row configuration (1 row vs. 2 rows), fastening mechanism (Latch Holder vs. Locking Ramp), and operating temperature range. The 179840-1 offers a wider temperature operating window and active product status. Insulation material composition differs slightly between Hirose glass-filled polyamide and TE Connectivity nylon 6/6.

Q: Are both connectors RoHS and REACH compliant?

A: Both connectors are REACH Unaffected and classified under ECCN EAR99. The 179840-1 is explicitly RoHS3 Compliant. Both meet UL94 V-0 flammability requirements.

Q: What is the significance of the two-row configuration in 179840-1?

A: The 179840-1 features a 2-row layout with 0.181" (4.60mm) row spacing, compared to the single-row design of DF7C-4P-3.96DSA(25). This affects the physical footprint and mating interface geometry. Compatibility depends on whether the mating connector or cable assembly accommodates the two-row pin arrangement.

Q: Are there inventory considerations for these parts?

A: DF7C-4P-3.96DSA(25) is obsolete with limited remaining stock (1071 Pcs reported). 179840-1 is an active product with robust inventory availability (3024 Pcs reported), supporting long-term supply chain reliability.
