DF14-2S-1.25C Equivalent & Substitute Parts

Part Overview

The DF14-2S-1.25C is a 2-position rectangular connector housing manufactured by Hirose Electric Co Ltd. This receptacle connector features a 1.25mm pitch and is designed for crimp termination applications. The part is currently classified as obsolete, making equivalent and substitute parts necessary for ongoing procurement and system maintenance. Substitute parts must maintain electrical and mechanical compatibility while meeting the same functional requirements for 2-position, 1.25mm pitch receptacle housing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DF14-2S-1.25C are classified based on their alignment with the critical parameters that define functional compatibility:

MFR Recommended Substitutes maintain identical or superior specifications across all critical parameters: 2-position count, 1.25mm pitch, receptacle configuration, female socket contact type, crimp termination, free hanging mounting, and polyamide insulation. These parts are direct functional equivalents.

Parametric Equivalents satisfy the core electrical and mechanical requirements (2-position, 1.25mm pitch, receptacle, female socket, crimp termination, free hanging mounting) but may differ in secondary characteristics such as insulation material composition, color, operating temperature range, or fastening mechanism. These parts are suitable for applications where the primary functional parameters are the determining factors.

The critical parameters for substitution are: connector type (receptacle), contact type (female socket), number of positions (2), pitch (1.25mm), mounting type (free hanging in-line), and contact termination (crimp).

Parameter Comparison

Engineering Selection Recommendations

DF14-2S-1.25C(10) is the primary substitute for the obsolete DF14-2S-1.25C. This part is manufactured by the same supplier (Hirose Electric Co Ltd) and maintains identical electrical and mechanical specifications. The part carries Active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment. This substitute is recommended for direct replacement in existing designs.

125CH-D-02 (Adam Tech) is a MFR recommended substitute that satisfies all critical functional parameters. The part is Active and ROHS3 compliant. The operating temperature range is -25°C ~ 85°C, which is narrower than the original part's -35°C ~ 85°C specification. This substitute is suitable for applications where the lower temperature limit of -25°C is acceptable. The fastening type is specified as Friction Lock, which differs from the original part.

10114826-00002LF (Amphenol ICC / FCI) is a parametric equivalent that meets all core functional requirements. This part is Active and RoHS compliant with an extended operating temperature range of -40°C ~ 105°C, providing superior thermal performance. The insulation material is specified as Polyamide (PA66), Nylon 6/6, and the color is Natural rather than Beige. REACH status is listed as Affected. This substitute is suitable for applications requiring extended temperature performance or where color variation is acceptable.

Selection should prioritize DF14-2S-1.25C(10) for direct replacement. Alternative substitutes should be evaluated based on specific application requirements regarding operating temperature range, color specification, and regulatory compliance status.

Frequently Asked Questions (FAQ)

Q: Can DF14-2S-1.25C(10) be used as a direct replacement for DF14-2S-1.25C?

A: Yes. DF14-2S-1.25C(10) maintains identical specifications for all critical parameters: 2-position count, 1.25mm pitch, receptacle configuration, female socket contact type, crimp termination, free hanging mounting, and polyamide insulation. The part is manufactured by Hirose Electric Co Ltd and carries Active product status.

Q: What is the primary difference between 125CH-D-02 and the original DF14-2S-1.25C?

A: The 125CH-D-02 is manufactured by Adam Tech and features a narrower operating temperature range (-25°C ~ 85°C versus -35°C ~ 85°C). The fastening type is specified as Friction Lock. All other critical functional parameters are identical. This substitute is suitable for applications where the lower temperature limit is acceptable.

Q: Why does 10114826-00002LF have a different color (Natural vs. Beige)?

A: Color is a secondary characteristic that does not affect electrical or mechanical function. The 10114826-00002LF is a parametric equivalent that satisfies all core functional requirements. Color selection should be based on application-specific requirements or design preferences.

Q: Is the extended operating temperature range of 10114826-00002LF (-40°C ~ 105°C) compatible with the original design?

A: Yes. The extended temperature range of 10114826-00002LF is a superset of the original specification (-35°C ~ 85°C). This part is suitable for applications requiring enhanced thermal performance or operation in extended temperature environments.

Q: What does "Contacts Not Included" mean in the part specifications?

A: This indicates that the connector housing is supplied without pre-installed contacts. Contacts must be sourced separately and crimped into the housing during assembly. This is standard for receptacle housing components.

Q: Are all substitute parts RoHS compliant?

A: DF14-2S-1.25C(10) and 125CH-D-02 carry ROHS3 compliance. 10114826-00002LF carries RoHS compliance. All three substitutes meet RoHS regulatory requirements.

Q: What is the significance of Moisture Sensitivity Level (MSL) 1?

A: MSL 1 indicates unlimited shelf life with no special moisture control requirements during storage or handling. All listed parts, including the original and substitutes, carry MSL 1 classification.
