Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF13-3P-1.25DSA(75) is determined by strict equivalence across the following critical parameters:

• Connector series and base product number (DF13)
• Number of positions (3)
• Mating pitch (0.049" / 1.25mm)
• Contact type and gender (Male Pin Header)
• Mounting method (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination type (Solder)
• Fastening mechanism (Detent Lock)
• Electrical ratings (1A current, 150V voltage)
• Operating temperature range (-35°C ~ 85°C)
• Material compliance (UL94 V-0, RoHS)

The DF13-3P-1.25DSA(25) meets all these criteria and is classified as an active product, making it a direct functional equivalent for the obsolete DF13-3P-1.25DSA(75).

Parameter Comparison

Engineering Selection Recommendations

The DF13-3P-1.25DSA(25) is the direct substitute for the obsolete DF13-3P-1.25DSA(75). Both components share identical mechanical and electrical specifications, with the primary distinction being product status and packaging format.

The substitute part is currently in active production with higher inventory availability (2572 Pcs vs. 936 Pcs for the original). The DF13-3P-1.25DSA(25) carries ROHS3 compliance, representing an updated regulatory certification compared to the original RoHS Compliant designation. Both parts maintain the same ECCN and HTSUS classifications.

From an engineering perspective, the DF13-3P-1.25DSA(25) provides equivalent performance across all electrical, mechanical, and thermal parameters. The packaging difference (Tube for the substitute vs. unspecified for the original) does not affect component functionality or board-level integration.

Frequently Asked Questions (FAQ)

Q: Can DF13-3P-1.25DSA(25) be used as a direct replacement for DF13-3P-1.25DSA(75)?

A: Yes. Both components are identical in connector type, position count, pitch, contact configuration, mounting method, and electrical ratings. The difference in part number suffix reflects packaging variation only.

Q: What is the significance of the part number suffix (75 vs. 25)?

A: The suffix indicates packaging specification. The DF13-3P-1.25DSA(25) is supplied in Tube packaging, while the original DF13-3P-1.25DSA(75) had unspecified packaging. This does not affect component performance or compatibility.

Q: Are there any compliance differences between the two parts?

A: The DF13-3P-1.25DSA(25) carries ROHS3 Compliant certification, while the original is listed as RoHS Compliant. Both meet the same electrical safety and environmental standards. The ROHS3 designation represents an updated compliance framework.

Q: What are the critical parameters for confirming substitution compatibility?

A: Verify that any replacement maintains: 3-position configuration, 1.25mm mating pitch, male pin header type, through-hole mounting, shrouded 4-wall design, solder termination, detent lock fastening, 1A current rating, 150V voltage rating, and -35°C to 85°C operating temperature range.

Q: Is the DF13-3P-1.25DSA(25) available in higher quantities?

A: Yes. Current inventory for the substitute is 2572 Pcs, compared to 936 Pcs for the obsolete original part, providing improved procurement availability.
