Substitute Part Grouping Explanation

Substitution eligibility for the DF14-6S-1.25C is determined by the following critical parameters: connector type (receptacle), contact type (female socket), number of positions (6), pitch (1.25mm), number of rows (1), mounting type (free hanging in-line), and contact termination method (crimp). All identified substitutes maintain these core electrical and mechanical specifications.

The substitute parts are categorized as follows:

MFR Recommended Substitutes: Parts that maintain identical specifications and are recommended by the original manufacturer or equivalent manufacturers for direct replacement.

Parametric Equivalents: Parts that satisfy all critical electrical and mechanical parameters but may differ in secondary characteristics such as color, fastening type, or temperature range extensions.

Engineering Selection Recommendations

DF14-6S-1.25C(10) is the primary recommended substitute. Manufactured by Hirose Electric Co Ltd, this part maintains identical electrical and mechanical specifications to the original DF14-6S-1.25C while offering active product status. It provides ROHS3 compliance and is available in higher inventory quantities (1521 pcs), ensuring supply continuity.

125CH-D-06 serves as an alternative MFR-recommended substitute from Adam Tech. This part satisfies all critical connector parameters and maintains active product status with ROHS3 compliance. The inclusion of friction lock fastening provides enhanced mechanical retention. The operating temperature minimum is -25°C, which is acceptable for applications not requiring the full -35°C lower limit of the original part.

10114826-00006LF functions as a parametric equivalent from Amphenol ICC (FCI). This part meets all core electrical and mechanical requirements and offers an extended operating temperature range (-40°C to 105°C), providing greater thermal flexibility. The natural color differs from the beige original specification. REACH status is affected, requiring verification for applications subject to REACH regulations. Inventory availability is significantly higher (16967 pcs).

Selection should prioritize DF14-6S-1.25C(10) for direct replacement applications requiring identical specifications and Hirose sourcing. Alternative substitutes are suitable when extended temperature performance, enhanced mechanical features, or alternative sourcing is required.

Frequently Asked Questions (FAQ)

Q: Can DF14-6S-1.25C(10) be used as a direct replacement for DF14-6S-1.25C?

A: Yes. DF14-6S-1.25C(10) maintains identical electrical and mechanical specifications including connector type, contact type, position count, pitch, mounting type, and termination method. The primary difference is product status (active vs. obsolete) and updated RoHS certification level.

Q: What is the significance of the pitch specification in connector substitution?

A: Pitch (0.049" or 1.25mm) defines the center-to-center spacing between contact positions. All substitute parts maintain this specification, ensuring mechanical and electrical compatibility with mating connectors and PCB layouts designed for the original DF14-6S-1.25C.

Q: Are there temperature range differences between substitutes?

A: Yes. The original DF14-6S-1.25C operates from -35°C to 85°C. DF14-6S-1.25C(10) matches this range. 125CH-D-06 operates from -25°C to 85°C (higher minimum temperature). 10114826-00006LF operates from -40°C to 105°C (extended range). Selection depends on application thermal requirements.

Q: What does "Contacts Not Included" mean?

A: The connector housing is supplied without pre-installed contacts. Contacts must be procured separately and crimped into the housing during assembly. This is standard for this connector category.

Q: How does insulation material differ between substitutes?

A: The original DF14-6S-1.25C uses Polyamide (PA) Nylon. Substitutes 125CH-D-06 and 10114826-00006LF use Polyamide (PA66) Nylon 6/6, which offers enhanced mechanical and thermal properties. Both materials are suitable for the specified operating conditions.

Q: What is the difference between RoHS and ROHS3 compliance?

A: Both indicate RoHS compliance. ROHS3 represents the current RoHS 3 directive standard. Both certifications satisfy RoHS requirements; ROHS3 reflects updated regulatory alignment.

Q: Does color difference affect electrical performance?

A: No. Color is a cosmetic specification. The beige color of DF14-6S-1.25C and 125CH-D-06 versus the natural color of 10114826-00006LF does not affect electrical function or mechanical compatibility. Selection should be based on application visual requirements.

Q: What does "REACH Affected" status mean for 10114826-00006LF?

A: REACH Affected indicates the part may contain substances regulated under REACH (Registration, Evaluation, Authorization and Restriction of Chemicals). Applications subject to REACH compliance requirements should verify regulatory status before selection.

Q: Are all substitutes available in the same packaging format?

A: No. DF14-6S-1.25C, DF14-6S-1.25C(10), and 125CH-D-06 are supplied in bulk packaging. 10114826-00006LF is supplied in bag packaging. Packaging format does not affect component function but may influence handling and storage procedures.
