Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF7-2P-3.96DS(25) is determined by strict alignment of the following critical parameters:

• Pitch - Mating: 0.156" (3.96mm) — mechanical and electrical compatibility requirement
• Number of Positions: 2 — circuit configuration requirement
• Number of Rows: 1 — layout requirement
• Connector Type: Header — functional role requirement
• Contact Type: Male Pin — mating interface requirement
• Mounting Type: Through Hole, Right Angle — PCB integration requirement
• Shrouding: Shrouded - 4 Wall — mechanical protection and keying requirement
• Termination: Solder — assembly process requirement
• Material Flammability Rating: UL94 V-0 — safety compliance requirement

The TE Connectivity AMP Connectors part number 2-647126-2 (MTA-156 series) meets all critical substitution criteria. Both connectors share identical pitch, position count, row configuration, connector type, contact type, mounting orientation, shrouding design, termination method, and flammability rating.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors part number 2-647126-2 is a direct functional substitute for the obsolete DF7-2P-3.96DS(25). Both components are classified as obsolete products, indicating end-of-life status from their respective manufacturers.

The substitute part demonstrates superior environmental performance with an extended operating temperature range (-55°C ~ 105°C versus -35°C ~ 85°C), providing additional thermal margin for applications requiring broader temperature tolerance. The substitute includes explicit voltage rating specification (600VAC) and RoHS compliance certification, both absent from the original part documentation.

All critical mechanical and electrical parameters align identically: pitch, position count, row configuration, connector type, contact type, mounting orientation, shrouding design, termination method, contact material, contact finish, and flammability rating. Both components maintain identical moisture sensitivity level (MSL 1) and export classification (EAR99).

Physical dimensions show minor variations in contact length and insulation height, which are typical manufacturing tolerances between different connector families and do not affect functional compatibility in standard board-to-cable/wire applications.

Frequently Asked Questions (FAQ)

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

A: Yes. Both connectors share identical pitch (0.156"), position count (2), row configuration (1), connector type (header), contact type (male pin), mounting type (through hole, right angle), shrouding design (shrouded 4-wall), termination method (solder), and flammability rating (UL94 V-0). These parameters define functional compatibility for board-to-cable/wire applications.

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

A: The substitute part features an extended operating temperature range (-55°C ~ 105°C versus -35°C ~ 85°C), explicit voltage rating (600VAC), RoHS compliance certification, and different insulation material composition (thermoplastic versus polyamide). Contact length and insulation height dimensions differ slightly between the two designs.

Q: Are there any mechanical compatibility concerns with PCB mounting?

A: Both connectors use through-hole, right-angle mounting with identical pitch spacing. Minor differences in contact length and insulation height are within standard manufacturing tolerances and do not affect PCB footprint compatibility or mating interface alignment.

Q: Does the substitute part meet the same safety and compliance standards?

A: Both parts carry UL94 V-0 flammability rating and EAR99 export classification. The substitute part includes RoHS compliance certification, which is not documented for the original part. Both maintain MSL 1 (unlimited moisture sensitivity level).

Q: What is the inventory status for these parts?

A: The Hirose DF7-2P-3.96DS(25) has 1,073 pieces in stock. The TE Connectivity 2-647126-2 has 712 pieces in stock. Both are classified as obsolete products.
