DF7-5P-3.96DS(25) Equivalent & Substitute Parts

Part Overview

The DF7-5P-3.96DS(25) is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for through-hole, right-angle board-to-cable/wire applications. This 5-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 active equivalent parts essential for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution of the DF7-5P-3.96DS(25) is determined by the following critical parameters:

Pitch - Mating: 0.156" (3.96mm) — must match exactly for mechanical compatibility
Number of Positions: 5 — connector must accommodate identical pin count
Connector Type: Header with Male Pin contacts
Mounting Type: Through Hole, Right Angle — PCB mounting orientation and method must align
Shrouding: Shrouded - 4 Wall — mechanical protection and keying requirements
Termination: Solder — connection method to PCB
Contact Material and Finish: Copper Alloy with Tin finish — electrical and corrosion resistance properties
Insulation Material: Glass-filled thermoplastic or polyamide — mechanical strength and thermal stability
Material Flammability Rating: UL94 V-0 — safety compliance requirement

The TE Connectivity AMP Connectors part 2-647126-5 (MTA-156 series) meets all critical substitution criteria and is classified as an active, manufacturer-recommended equivalent.

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 2-647126-5 is the manufacturer-recommended equivalent for the obsolete DF7-5P-3.96DS(25). Selection is supported by the following factors:

All critical electrical and mechanical parameters align with the original specification
The substitute part is active and in production, ensuring long-term availability
Both parts carry UL94 V-0 flammability certification
The TE part operates across an extended temperature range (-55°C ~ 105°C), providing broader environmental compatibility than the original (-35°C ~ 85°C)
Both parts maintain MSL 1 (Unlimited) moisture sensitivity classification
Contact geometry variations (mating length, post length, insulation height) are within acceptable tolerance for standard board-to-cable/wire applications using 0.156" pitch connectors
RoHS3 compliance of the substitute part aligns with current regulatory requirements

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 2-647126-5 be used as a direct replacement for the DF7-5P-3.96DS(25)?

A: Yes. Both connectors share identical pitch (0.156"), position count (5), mounting type (through-hole right-angle), shrouding (4-wall), and termination method (solder). Mechanical and electrical compatibility is established.

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

A: The TE 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 variations are typical among equivalent connectors in this category and do not affect functional compatibility in standard applications.

Q: Why is the operating temperature range different?

A: The TE Connectivity part is rated for -55°C ~ 105°C, exceeding the original -35°C ~ 85°C specification. This represents an enhancement in environmental capability and does not create compatibility issues.

Q: Are there any fastening type differences?

A: Yes. The original uses a Latch Holder fastening type, while the TE substitute uses Friction Lock. Both are standard fastening mechanisms for 0.156" pitch connectors and provide equivalent retention in board-to-cable/wire configurations.

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

A: The TE Connectivity 2-647126-5 is currently active in production with 1039 pieces in stock, ensuring reliable procurement compared to the obsolete DF7-5P-3.96DS(25).
