Substitute Part Grouping Explanation

Substitution eligibility for the DF13-3P-1.25V(20) is determined by the following critical parameters:

Connector type (Header), contact type (Male Pin), and pitch (1.25mm)
Number of positions (3) and rows (1)
Mounting type (Surface Mount) and termination method (Solder)
Electrical ratings: 1A current, 150V voltage
Operating temperature range compatibility
Fastening mechanism (Detent Lock)
Shrouding configuration and insulation material

The identified substitutes maintain these core specifications while differing in secondary attributes such as shrouding wall count, packaging format, and product status.

Engineering Selection Recommendations

DF13-3P-1.25V(75) serves as a direct Hirose Electric equivalent with identical electrical and mechanical specifications. This part maintains the same pitch, position count, current/voltage ratings, and operating temperature range. The primary difference is shrouding configuration (3-wall versus 4-wall) and product status (Last Time Buy). This variant is suitable for applications where the reduced shrouding does not impact mechanical requirements. RoHS compliance is confirmed for this variant.

M30-6000346 (Harwin Inc.) is the manufacturer-recommended alternative, offering active product status and full ROHS3 compliance. This part maintains all critical electrical parameters and mechanical compatibility. Differences include insulation material composition (PA6T versus standard PA), operating temperature lower limit (-25°C versus -35°C), and packaging format (Bulk). The M30-6000346 is appropriate for new designs and applications where extended low-temperature operation below -25°C is not required.

Selection between substitutes depends on procurement timeline, compliance requirements, and thermal operating envelope. The M30-6000346 is preferred for new production due to active status and enhanced compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can DF13-3P-1.25V(75) be used as a direct replacement for DF13-3P-1.25V(20)?

A: Yes. Both parts share identical pitch (1.25mm), position count (3), electrical ratings (1A/150V), operating temperature range (-35°C to 85°C), and mounting specifications. The difference in shrouding wall count (3 versus 4) does not affect electrical function or mating compatibility.

Q: What is the primary difference between the Hirose and Harwin alternatives?

A: The M30-6000346 (Harwin) differs in product status (Active versus Last Time Buy), compliance certifications (ROHS3 versus RoHS), insulation material (PA6T versus PA), and operating temperature lower limit (-25°C versus -35°C). Electrical and mechanical compatibility remain equivalent.

Q: Is the M30-6000346 suitable for applications requiring -35°C operation?

A: No. The M30-6000346 operating temperature range begins at -25°C. For applications requiring -35°C minimum operation, the DF13-3P-1.25V(75) is the appropriate choice.

Q: What packaging formats are available for these substitutes?

A: DF13-3P-1.25V(20) is supplied in standard packaging (not specified). DF13-3P-1.25V(75) is packaged in Tube format. M30-6000346 is supplied in Bulk packaging.

Q: Are all three parts RoHS compliant?

A: DF13-3P-1.25V(75) is RoHS Compliant. M30-6000346 is ROHS3 Compliant. RoHS status for DF13-3P-1.25V(20) is not specified in available documentation.
