DF14-7S-1.25C Equivalent & Substitute Parts

Part Overview

The DF14-7S-1.25C is a 7-position rectangular connector housing manufactured by Hirose Electric Co Ltd, designed for applications requiring a 0.049" (1.25mm) pitch receptacle with crimp termination. This part is classified as Obsolete, making identification of functionally equivalent alternatives essential for ongoing production support and design continuity. Substitute parts must maintain identical electrical and mechanical specifications to ensure direct interchangeability without circuit redesign or mechanical modification.

Engineering Selection Recommendations

DF14-7S-1.25C(10) is the primary substitute. This part is manufactured by Hirose Electric Co Ltd, the original equipment manufacturer, and maintains identical electrical and mechanical specifications to the obsolete DF14-7S-1.25C. The only difference is packaging format (Bulk) and product status (Active). This part carries ROHS3 compliance and is currently in active production with 942 units in stock.

125CH-D-07 is an alternative substitute manufactured by Adam Tech. This part meets all critical substitution parameters with the following distinctions: it employs Polyamide (PA66) Nylon 6/6 insulation material versus the original Polyamide (PA) Nylon composition, operates across a reduced temperature range (-25°C ~ 85°C versus -35°C ~ 85°C), and includes a Friction Lock fastening feature not specified in the original part. This part is Active and carries ROHS3 compliance with 2010 units in stock.

Frequently Asked Questions (FAQ)

Q: Can DF14-7S-1.25C(10) be used as a direct replacement for DF14-7S-1.25C?

A: Yes. DF14-7S-1.25C(10) is electrically and mechanically equivalent to DF14-7S-1.25C. Both parts share identical connector type, contact configuration, pitch, mounting method, and operating temperature range. The primary difference is product status (Active versus Obsolete) and packaging format.

Q: What are the key differences between the two substitute options?

A: DF14-7S-1.25C(10) is the OEM substitute from Hirose Electric Co Ltd with identical specifications. 125CH-D-07 is a cross-manufacturer alternative from Adam Tech with three notable differences: insulation material composition (PA66 versus PA), minimum operating temperature (-25°C versus -35°C), and inclusion of a Friction Lock fastening feature. Selection depends on application temperature requirements and fastening method compatibility.

Q: Is the 125CH-D-07 suitable for applications requiring -35°C operation?

A: No. The 125CH-D-07 operates from -25°C to 85°C, which does not meet the original specification of -35°C to 85°C. Applications requiring -35°C minimum operating temperature must use DF14-7S-1.25C(10).

Q: Are all three parts RoHS compliant?

A: Yes. DF14-7S-1.25C carries RoHS compliance. Both DF14-7S-1.25C(10) and 125CH-D-07 carry ROHS3 compliance, which represents a higher standard of environmental and hazardous substance restriction.

Q: Do these parts include contacts?

A: No. Both the original DF14-7S-1.25C and substitute 125CH-D-07 are specified as housings without included contacts. Contacts must be sourced separately and crimped into the housing.
