DF7-6P-3.96DSA(25) Equivalent & Substitute Parts

Part Overview

The DF7-6P-3.96DSA(25) is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for through-hole mounting with 6 positions at 0.156" (3.96mm) pitch. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and procurement continuity. Substitute parts must maintain compatibility across pitch, position count, mounting type, and electrical characteristics to ensure direct board-level interchangeability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF7-6P-3.96DSA(25) is determined by the following critical parameters:

• Pitch - Mating: Must be 0.156" (3.96mm) to ensure mechanical and electrical alignment with mating connectors
• Number of Positions: Must be 6 to maintain pin count compatibility
• Connector Type: Must be Header for board-to-cable/wire configuration
• Mounting Type: Must be Through Hole for PCB integration
• Shrouding: Must be Shrouded - 4 Wall to maintain mechanical protection and alignment
• Contact Material & Finish: Copper Alloy with Tin finish ensures electrical performance and corrosion resistance
• Insulation Material Flammability: UL94 V-0 rating required for safety compliance

Two substitute parts meet these criteria with documented compatibility:

179841-1 (TE Connectivity AMP Connectors): Maintains 0.156" pitch, 6-position configuration, through-hole mounting, and shrouded design. Contact type differs (Tab vs. Male Pin) but electrical function remains equivalent. Row configuration differs (2 rows vs. 1 row), introducing a mechanical variation that requires board layout verification.

B6P-VH-FB-B (JST Sales America Inc.): Maintains identical pitch, position count, mounting type, and shrouding. Contact type matches (Male Pin). Single-row configuration aligns with original design. Insulation material differs (PBT vs. PA) but both meet UL94 V-0 flammability requirements.

Parameter Comparison

Engineering Selection Recommendations

B6P-VH-FB-B is the primary substitute for direct replacement applications. This part maintains single-row configuration matching the original design, identical contact type (Male Pin), and equivalent electrical specifications. The part is active in production with ROHS3 compliance and UL94 V-0 flammability rating. Operating temperature range (-25°C ~ 85°C) covers the original specification minimum of -35°C, suitable for most applications within the stated -35°C ~ 85°C envelope.

179841-1 serves as an alternative where row configuration flexibility exists. This part introduces a 2-row layout with Tab contact type, requiring PCB layout modification. The extended operating temperature range (-30°C ~ 105°C) provides thermal margin beyond the original specification. ROHS3 compliance and UL94 V-0 rating ensure regulatory alignment. Selection of this part requires verification that the dual-row footprint and Tab contact configuration are compatible with existing mating connectors and board design.

Both substitutes maintain the critical 0.156" pitch, 6-position count, through-hole mounting, and shrouded design necessary for functional equivalence. Compliance certifications (UL94 V-0, ROHS3, MSL 1) are consistent across all options.

Frequently Asked Questions (FAQ)

Q: Can B6P-VH-FB-B replace DF7-6P-3.96DSA(25) without PCB modification?

A: Yes. B6P-VH-FB-B maintains identical pitch (0.156"), position count (6), row configuration (1), and contact type (Male Pin). No PCB layout changes are required for direct substitution.

Q: Why does 179841-1 have a different row configuration?

A: 179841-1 is a 2-row design with Tab contacts, differing from the original 1-row Male Pin configuration. This part requires PCB footprint verification before selection. The dual-row layout may not be compatible with existing mating connectors designed for single-row headers.

Q: Are all substitute parts RoHS compliant?

A: B6P-VH-FB-B and 179841-1 are both ROHS3 compliant. The original DF7-6P-3.96DSA(25) RoHS status is not specified in available documentation.

Q: What is the temperature operating range difference?

A: DF7-6P-3.96DSA(25) operates -35°C ~ 85°C. B6P-VH-FB-B operates -25°C ~ 85°C (10°C higher minimum). 179841-1 operates -30°C ~ 105°C (5°C higher minimum, 20°C higher maximum). For applications requiring -35°C operation, B6P-VH-FB-B may require thermal testing validation.

Q: Do all parts have the same pitch and position count?

A: Yes. All three parts maintain 0.156" (3.96mm) pitch and 6-position configuration, ensuring mechanical compatibility with standard mating connectors designed for this specification.

Q: What packaging formats are available?

A: DF7-6P-3.96DSA(25) packaging is not specified. 179841-1 is supplied in Tray packaging. B6P-VH-FB-B is supplied in Bulk packaging. Packaging selection may affect procurement and handling procedures.
