DF7C-10P-3.96DSA(25) Equivalent & Substitute Parts

Part Overview

The DF7C-10P-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 10-position shrouded header operates at 0.156" (3.96mm) pitch and features tin-plated copper alloy contacts with polyamide insulation. The product is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF7C-10P-3.96DSA(25) is constrained by the following critical parameters:

• Pitch - Mating: 0.156" (3.96mm) — must match exactly for mechanical and electrical compatibility
• Connector Type: Header with male pins for board-to-cable/wire applications
• Mounting Type: Through hole solder termination
• Shrouding: 4-wall shrouded design for polarization and mechanical protection
• Contact Material and Finish: Tin-plated contacts for corrosion resistance

The substitute part 1877285-9 (TE Connectivity AMP Connectors) shares the same pitch, connector type, mounting method, shrouding configuration, and contact finish specifications. However, this substitute operates with 9 positions rather than 10, representing a reduced-capacity alternative suitable only where system design permits position reduction.

Parameter Comparison

Engineering Selection Recommendations

The DF7C-10P-3.96DSA(25) is obsolete; procurement of new units is not available. The 1877285-9 substitute from TE Connectivity AMP Connectors is an active product with current manufacturing support and inventory availability.

Both parts meet UL94 V-0 flammability requirements and share identical pitch, shrouding, and contact finish specifications. The substitute operates across a wider temperature range (-25°C ~ 105°C versus -35°C ~ 85°C) and includes specified electrical ratings (7.5A at 250VAC).

Selection of the 1877285-9 as a substitute is valid only where system design accommodates the reduction from 10 to 9 contact positions. Applications requiring all 10 positions must pursue alternative sourcing strategies or design modifications.

Frequently Asked Questions (FAQ)

Q: Can the 1877285-9 directly replace the DF7C-10P-3.96DSA(25)?

A: Direct replacement is possible only if the application uses 9 or fewer signal/power connections. The substitute has one fewer position, so systems requiring all 10 positions cannot use this part without circuit redesign.

Q: Are the pitch and shrouding specifications identical?

A: Yes. Both parts use 0.156" (3.96mm) pitch and 4-wall shrouded design, ensuring mechanical compatibility with mating connectors and PCB layouts designed for the original part.

Q: What are the electrical differences?

A: The original part does not specify current or voltage ratings. The substitute is rated for 7.5A at 250VAC, providing defined electrical performance for general purpose, industrial, and lighting applications.

Q: How do the operating temperature ranges compare?

A: The DF7C-10P-3.96DSA(25) operates from -35°C to 85°C. The 1877285-9 operates from -25°C to 105°C, offering a wider upper temperature limit but a narrower lower limit. Application requirements determine if this difference is acceptable.

Q: Are both parts RoHS and REACH compliant?

A: The original part lists REACH Unaffected status. The substitute is ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards.

Q: What is the contact material difference?

A: The original uses copper alloy contacts; the substitute uses brass contacts. Both are tin-plated and suitable for solder termination in through-hole applications.
