DF7C-8P-3.96DSA(25) Equivalent & Substitute Parts

Part Overview

The DF7C-8P-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 8-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 equivalent substitute parts essential for ongoing maintenance, repair, and legacy system support where original components are no longer readily available.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF7C-8P-3.96DSA(25) is determined by the following critical parameters that must remain consistent:

• Connector Type & Contact Type: Header with Male Pin contacts
• Position Count & Pitch: 8 positions at 0.156" (3.96mm) mating pitch
• Mounting & Termination: Through-hole solder termination
• Shrouding Configuration: Shrouded 4-wall design
• Application Style: Board to Cable/Wire connectivity
• Contact Geometry: Square contact shape
• Flammability Compliance: UL94 V-0 rating

The substitute part 1877285-8 (TE Connectivity AMP Connectors) satisfies all critical substitution criteria. Both connectors maintain identical pitch, position count, mounting method, shrouding type, and termination approach, ensuring mechanical and electrical compatibility in legacy applications.

Parameter Comparison

Engineering Selection Recommendations

The 1877285-8 (TE Connectivity) serves as a direct substitute for the obsolete DF7C-8P-3.96DSA(25). Both connectors maintain identical electrical and mechanical interface specifications, ensuring pin-for-pin compatibility in existing PCB layouts and cable assemblies.

The substitute part offers the advantage of active product status with current manufacturing availability (24,845 pcs in stock versus 1,097 pcs for the obsolete original). Both parts carry UL94 V-0 flammability certification and REACH compliance, meeting the same regulatory requirements.

The TE Connectivity part features an extended operating temperature range (-25°C ~ 105°C versus -35°C ~ 85°C), providing broader thermal performance capability. The substitute also includes specified current and voltage ratings (7.5A at 250VAC) and incorporates a board guide feature not present in the original design.

Frequently Asked Questions (FAQ)

Q: Can the 1877285-8 be used as a direct replacement for the DF7C-8P-3.96DSA(25)?

A: Yes. Both connectors share identical pitch (0.156"), position count (8), mounting method (through-hole solder), shrouding configuration (4-wall), and contact geometry (square male pins). Mechanical and electrical compatibility is maintained.

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

A: The primary differences are insulation material composition (PA/Nylon versus PBT), operating temperature range (DF7C: -35°C to 85°C; 1877285-8: -25°C to 105°C), fastening mechanism (Latch Holder versus Locking Ramp), and the inclusion of a board guide feature in the TE Connectivity part. The substitute also provides specified electrical ratings (7.5A, 250VAC).

Q: Are there any compliance or certification concerns with substitution?

A: No. Both parts carry identical UL94 V-0 flammability ratings, REACH compliance status, and EAR99 export classification. Moisture sensitivity levels are equivalent (MSL 1 - Unlimited).

Q: What is the availability status of each part?

A: The DF7C-8P-3.96DSA(25) is obsolete with limited remaining inventory (1,097 pcs). The 1877285-8 is an active product with substantial current availability (24,845 pcs).

Q: Are there any thermal performance considerations?

A: The substitute part supports a wider operating temperature range, extending to 105°C maximum versus 85°C for the original. For applications operating within the original specification range (-35°C to 85°C), both parts perform equivalently.
