Substitute Part Grouping Explanation

Substitution for the DF13-4P-1.25DSA is determined by strict alignment of the following critical parameters:

Connector type (Header)
Contact type (Male Pin)
Pitch specification (0.049" / 1.25mm)
Number of positions (4)
Number of rows (1)
Mounting method (Through Hole)
Shrouding configuration (Shrouded - 4 Wall)
Fastening mechanism (Detent Lock)
Termination method (Solder)
Contact material (Brass)
Insulation material (Polyamide/Nylon)
Electrical ratings (minimum 1A per contact, minimum 150V)
Flammability compliance (UL94 V-0)
RoHS compliance status

The identified substitutes meet these criteria and are available from active product lines, addressing the obsolescence of the original part.

Engineering Selection Recommendations

DF13-4P-1.25DSA(05) is the primary substitute, manufactured by Hirose Electric Co Ltd with active product status. This part maintains identical electrical and mechanical specifications to the original DF13-4P-1.25DSA, including voltage rating (150V), operating temperature range (-35°C ~ 85°C), and all dimensional parameters. The part carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements.

M30-6100446 from Harwin Inc. is an alternative substitute with active product status. This part matches all critical mechanical parameters and connector specifications. The voltage rating is 100V, which is lower than the original 150V specification. The operating temperature minimum is -25°C compared to -35°C for the original part. The insulation material is specified as Polyamide (PA66), Nylon 6/6, and packaging is provided in tube format rather than bulk. This part also carries ROHS3 compliance and REACH unaffected status.

Selection between DF13-4P-1.25DSA(05) and M30-6100446 depends on application voltage and temperature requirements. For applications requiring the full 150V rating or -35°C minimum operating temperature, DF13-4P-1.25DSA(05) is the appropriate choice. For applications within 100V and -25°C to 85°C operating range, M30-6100446 is functionally equivalent.

Frequently Asked Questions (FAQ)

Q: Why is the DF13-4P-1.25DSA listed as obsolete?

A: The DF13-4P-1.25DSA is no longer in active production. The DF13-4P-1.25DSA(05) variant is the current active product from Hirose Electric Co Ltd and serves as the direct replacement.

Q: Can DF13-4P-1.25DSA(05) be used as a direct replacement?

A: Yes. The DF13-4P-1.25DSA(05) maintains identical electrical ratings (1A per contact, 150V), mechanical dimensions, connector configuration (4-position, 1.25mm pitch, shrouded 4-wall, detent lock), and operating temperature range (-35°C ~ 85°C). No design modifications are required.

Q: What are the key differences between DF13-4P-1.25DSA(05) and M30-6100446?

A: Both parts share identical connector type, pitch, position count, mounting method, and shrouding. The M30-6100446 has a lower voltage rating (100V versus 150V), a higher minimum operating temperature (-25°C versus -35°C), and is packaged in tubes rather than bulk. The insulation material specification differs slightly (PA66 versus PA).

Q: Which substitute should I select for my application?

A: If your application operates at voltages up to 150V and temperatures as low as -35°C, use DF13-4P-1.25DSA(05). If your application operates within 100V and -25°C to 85°C, either part is suitable; M30-6100446 may be selected based on packaging preference or availability.

Q: Are both substitutes RoHS compliant?

A: Yes. Both DF13-4P-1.25DSA(05) and M30-6100446 carry ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements.

Q: What is the difference in packaging between the substitutes?

A: DF13-4P-1.25DSA(05) is supplied in bulk packaging. M30-6100446 is supplied in tube packaging. Packaging selection may affect procurement quantities and handling procedures but does not affect electrical or mechanical performance.

Q: Are the contact finishes identical across all three parts?

A: Yes. All three parts feature tin contact finish on both mating and post surfaces, with brass contact material and polyamide/nylon insulation.
