DF7C-7P-3.96DSA(25) Equivalent & Substitute Parts

Part Overview

The DF7C-7P-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 7-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 compatible substitute parts essential for ongoing system support and component procurement.

Substitute Part Grouping Explanation

Substitution of the DF7C-7P-3.96DSA(25) is determined by strict alignment of the following critical parameters:

Connector type (Header) and contact type (Male Pin)
Mating pitch (0.156" / 3.96mm)
Position count (7 positions, single row)
Shrouding configuration (Shrouded - 4 Wall)
Mounting method (Through Hole)
Termination type (Solder)
Application style (Board to Cable/Wire)
Contact shape (Square)
Flammability compliance (UL94 V-0)

The substitute part 1877285-7 from TE Connectivity AMP Connectors meets all these core requirements. Both connectors maintain identical mating pitch, position configuration, shrouding design, and mounting characteristics. Variations in contact length, insulation height, and material composition (brass vs. copper alloy, PBT vs. polyamide) remain within acceptable mechanical and electrical tolerances for this connector category.

Engineering Selection Recommendations

The DF7C-7P-3.96DSA(25) is classified as obsolete. The substitute part 1877285-7 is active and maintains full availability. Both connectors comply with UL94 V-0 flammability requirements and REACH regulations. The 1877285-7 offers an extended operating temperature range (-25°C ~ 105°C versus -35°C ~ 85°C) and includes current and voltage ratings (7.5A at 250VAC) not specified for the original part. The substitute maintains mechanical compatibility through identical mating pitch, position count, shrouding, and mounting configuration. Selection of 1877285-7 is appropriate for applications requiring active component sourcing and compliance with current regulatory standards.

Frequently Asked Questions (FAQ)

Q: Can 1877285-7 be used as a direct replacement for DF7C-7P-3.96DSA(25)?

A: Yes. Both connectors share identical mating pitch (0.156" / 3.96mm), position count (7), row configuration (1), shrouding design (4-wall), mounting type (through-hole), and termination method (solder). Mechanical and electrical compatibility is maintained.

Q: What are the differences between these two connectors?

A: The primary differences are contact material (copper alloy vs. brass), insulation material (polyamide vs. PBT), contact length dimensions, and operating temperature range. The 1877285-7 provides a wider temperature operating window and specified current/voltage ratings. These variations do not affect substitution suitability for standard board-to-cable applications.

Q: Are there any compliance or certification differences?

A: Both connectors meet UL94 V-0 flammability standards and are REACH unaffected. The 1877285-7 is RoHS3 compliant. Both carry identical ECCN (EAR99) and HTSUS classifications.

Q: What is the packaging difference?

A: The original DF7C-7P-3.96DSA(25) is listed with unspecified packaging. The 1877285-7 is supplied in bulk packaging. Confirm packaging requirements with your procurement specification.

Q: Does the insulation color difference affect compatibility?

A: No. Insulation color (beige vs. white) is a visual identifier only and does not affect electrical or mechanical performance in board-to-cable/wire applications.

Q: Are there any applications where 1877285-7 cannot substitute for DF7C-7P-3.96DSA(25)?

A: Substitution is valid for all standard board-to-cable/wire connector applications. The extended temperature range and specified electrical ratings of 1877285-7 make it suitable for general purpose, industrial, and lighting applications.
