Engineering Selection Recommendations

DF13-6P-1.25V(75) (Hirose Electric Co Ltd): This direct Hirose equivalent maintains identical electrical and mechanical specifications to the DF13-6P-1.25V(20). The primary difference is shrouding configuration (3-wall versus 4-wall) and product status (Last Time Buy). This part is suitable for applications where the reduced shrouding does not impact mechanical requirements. RoHS Compliance status is confirmed.

M30-6000646 (Harwin Inc.): This manufacturer-recommended substitute provides active product status with full ROHS3 and REACH compliance. The M30 series maintains the same pitch, position count, electrical ratings, and core mechanical interface. Differences include insulation material composition (PA6T versus standard PA) and operating temperature lower limit (-25°C versus -35°C). This part is appropriate for new designs and applications requiring long-term component availability.

Selection between DF13-6P-1.25V(75) and M30-6000646 depends on application requirements: choose DF13-6P-1.25V(75) for direct Hirose continuity; select M30-6000646 for active product status and extended supply chain assurance.

Frequently Asked Questions (FAQ)

Q: Can DF13-6P-1.25V(75) be used as a direct replacement for DF13-6P-1.25V(20)?

A: Yes. Both parts share identical pitch (1.25mm), position count (6), electrical ratings (1A/150V), mounting type (surface mount), and termination method (solder with detent lock). The difference in shrouding design (3-wall versus 4-wall) does not affect electrical compatibility. Mechanical fit must be verified against the mating connector design.

Q: What is the significance of the shrouding difference between the DF13-6P-1.25V(20) and DF13-6P-1.25V(75)?

A: Shrouding provides mechanical guidance and polarization. The 4-wall design on DF13-6P-1.25V(20) offers greater mechanical constraint than the 3-wall design on DF13-6P-1.25V(75). Selection depends on the mating connector's shrouding compatibility and application mechanical requirements.

Q: Is M30-6000646 electrically compatible with DF13-6P-1.25V(20)?

A: Yes. Both parts meet the same electrical specifications: 1A current rating, 150V voltage rating, and identical pitch/position configuration. The M30-6000646 uses PA6T insulation material instead of standard PA, which provides enhanced thermal and chemical resistance. Operating temperature range differs at the lower limit (-25°C versus -35°C).

Q: Why is M30-6000646 recommended as a manufacturer substitute?

A: M30-6000646 is an active product with confirmed ROHS3 and REACH compliance, ensuring long-term availability and regulatory alignment. It maintains all critical electrical and mechanical parameters while offering superior product lifecycle status compared to the Obsolete DF13-6P-1.25V(20).

Q: What packaging options are available for these substitute parts?

A: DF13-6P-1.25V(75) is supplied in Tube packaging. M30-6000646 is supplied in Tube packaging. Packaging format does not affect component functionality or electrical performance.

Q: Are there temperature range limitations when substituting M30-6000646?

A: M30-6000646 operates from -25°C to 85°C, compared to DF13-6P-1.25V(20) at -35°C to 85°C. Applications requiring operation below -25°C must retain the original Hirose part or verify M30-6000646 suitability through thermal testing.
