DF7-6P-3.96DS(26) Equivalent & Substitute Parts

Part Overview

The DF7-6P-3.96DS(26) is a rectangular connector header manufactured by Hirose Electric Co., Ltd., designed for through-hole, right-angle board-to-cable/wire applications. This 6-position connector operates at 0.156" (3.96mm) pitch with shrouded 4-wall construction and solder termination. The product is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system support, maintenance, and new production runs where legacy compatibility is required.

Substitute Part Grouping Explanation

Substitution of the DF7-6P-3.96DS(26) is determined by strict alignment of the following electrical and mechanical parameters:

• Pitch - Mating: 0.156" (3.96mm) — determines physical mating compatibility with corresponding receptacles
• Number of Positions: 6 — defines circuit count and connector footprint
• Connector Type & Contact Type: Header with Male Pin — establishes the connector role in the board-to-cable interface
• Mounting Type: Through Hole, Right Angle — specifies PCB assembly method and spatial orientation
• Shrouding: Shrouded - 4 Wall — ensures mechanical protection and polarization
• Termination: Solder — defines connection method to PCB
• Contact Shape: Square — ensures proper mating with corresponding female contacts
• Material Flammability Rating: UL94 V-0 — meets safety compliance requirements

The TE Connectivity AMP Connectors part 2-647126-6 (MTA-156 series) satisfies all mandatory substitution criteria. While minor variations exist in contact dimensions, insulation height, and operating temperature range, these differences do not prevent functional equivalence in applications designed for the DF7-6P-3.96DS(26).

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 2-647126-6 (MTA-156 series) is the primary equivalent substitute for the obsolete DF7-6P-3.96DS(26). Selection is supported by the following factors:

• Product Status: The TE Connectivity part maintains active production status, ensuring long-term availability and supply chain continuity.
• Compliance & Certifications: Both connectors meet UL94 V-0 flammability requirements and share identical ECCN (EAR99) and HTSUS classifications, confirming regulatory equivalence.
• Functional Compatibility: All critical mating parameters—pitch, position count, contact type, mounting method, and shrouding—are identical, enabling direct substitution in applications originally designed for the DF7-6P-3.96DS(26).
• Environmental Capability: The TE Connectivity part offers an extended operating temperature range (-55°C ~ 105°C) compared to the original (-35°C ~ 85°C), providing greater thermal margin in demanding applications.
• Moisture Sensitivity: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture-related handling restrictions.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 2-647126-6 directly replace the DF7-6P-3.96DS(26) in existing designs?

A: Yes. Both connectors share identical pitch (0.156"), position count (6), contact type (male pin), mounting method (through-hole right-angle), and shrouding (4-wall). The mating interface is mechanically and electrically compatible with corresponding receptacles designed for the original part.

Q: What are the differences in contact dimensions between these two connectors?

A: The TE Connectivity part has a slightly longer mating contact (0.300" vs. 0.276") and a slightly shorter post contact (0.125" vs. 0.138"). The insulation height is also greater (0.455" vs. 0.303"). These dimensional variations do not affect mating compatibility but may require PCB layout verification in space-constrained applications.

Q: Does the contact finish difference (Gold vs. Tin) affect compatibility?

A: No. Both finishes provide adequate electrical conductivity and corrosion resistance for the intended application. The gold finish on the original part offers marginally superior contact resistance characteristics, but the tin finish on the substitute meets all functional requirements. Both finishes are compatible with standard solder termination processes.

Q: Are there fastening differences between the two connectors?

A: Yes. The DF7-6P-3.96DS(26) uses a Latch Holder fastening type, while the TE Connectivity 2-647126-6 uses Friction Lock. Both mechanisms provide secure mating and are functionally equivalent for board-to-cable applications. No design changes are required.

Q: What is the inventory status of the substitute part?

A: The TE Connectivity 2-647126-6 has 816 pieces in new original stock, compared to 963 pieces available for the obsolete Hirose part. The active production status of the TE Connectivity part ensures continued availability for future procurement.

Q: Are both connectors RoHS compliant?

A: The TE Connectivity 2-647126-6 is explicitly RoHS Compliant. The Hirose part does not specify RoHS status in the provided data. Both parts carry identical REACH status classifications and ECCN/HTSUS codes, confirming regulatory alignment for industrial and commercial applications.
