DF7C-6P-3.96DSA(25) Equivalent & Substitute Parts

Part Overview

The DF7C-6P-3.96DSA(25) is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for through-hole mounting in board-to-cable/wire applications. This 6-position connector features a 0.156" (3.96mm) pitch and shrouded 4-wall design with solder termination. The product is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF7C-6P-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: 6 — connector must accommodate the same signal count
• Connector Type: Header — must be a header configuration for board-to-cable/wire interface
• Mounting Type: Through Hole — PCB mounting method must remain consistent
• Shrouding: Shrouded - 4 Wall — mechanical protection and keying alignment requirement
• Termination: Solder — connection method to PCB must be solder-compatible
• Material Flammability Rating: UL94 V-0 — safety certification must be maintained or exceeded

The substitute part 179841-1 (TE Connectivity AMP Connectors) meets these core substitution criteria. However, differences exist in contact configuration, row structure, and operating temperature range that must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The 179841-1 substitute part is actively manufactured and maintains UL94 V-0 flammability compliance, addressing the primary concern of component obsolescence for the DF7C-6P-3.96DSA(25). Both parts share identical pitch, position count, mounting method, and shrouding configuration.

Key differences requiring evaluation:

• Row Configuration: The substitute features 2 rows versus 1 row in the original. PCB layout and connector housing compatibility must be verified.
• Contact Type: The substitute uses tab contacts instead of male pins. Mating interface compatibility with existing cable assemblies or receptacles must be confirmed.
• Operating Temperature Range: The substitute supports -30°C ~ 105°C versus -35°C ~ 85°C. Applications requiring the original's lower temperature limit require assessment.
• Termination Method: The substitute includes kinked pin termination in addition to solder, providing alternative assembly options.

Selection of 179841-1 is appropriate for applications where the 2-row configuration and tab contact type are compatible with existing system design. For applications requiring strict 1-row, male-pin configuration, alternative substitutes should be evaluated.

Frequently Asked Questions (FAQ)

Q: Can 179841-1 directly replace DF7C-6P-3.96DSA(25) in existing PCB designs?

A: Direct replacement requires verification of PCB footprint compatibility. The 2-row configuration of 179841-1 differs from the 1-row layout of the original part. Mechanical fit and electrical routing must be confirmed before implementation.

Q: Are the contact interfaces compatible between these two parts?

A: The original part features male pin contacts while 179841-1 uses tab contacts. Compatibility depends on the mating receptacle or cable assembly design. Existing connectors designed for male pins may not interface with tab contacts without adapter solutions.

Q: What is the significance of the pitch specification in substitution?

A: Pitch (0.156" / 3.96mm) determines the spacing between contact positions and is critical for mechanical alignment and electrical performance. Both parts share identical pitch, ensuring compatibility at this fundamental level.

Q: Does the operating temperature difference affect substitution suitability?

A: The substitute part supports a wider temperature range (-30°C ~ 105°C) compared to the original (-35°C ~ 85°C). For applications operating within the original's specified range, the substitute is acceptable. Applications requiring operation below -30°C require alternative evaluation.

Q: Are both parts RoHS compliant?

A: The original part lists REACH Unaffected status. The substitute is ROHS3 Compliant. Regulatory compliance requirements for your application should be verified against these designations.

Q: What packaging considerations apply to these parts?

A: The original part packaging is not specified. The substitute is supplied in Tray packaging. Procurement and handling procedures may differ based on packaging format.
