Substitute Part Grouping Explanation

Substitution eligibility for the DF13-3P-1.25DS(77) is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Header with male pins, 3-position layout
• Pitch Specification: 0.049" (1.25mm) mating pitch
• Mounting Geometry: Through-hole, right-angle orientation
• Electrical Ratings: 1A current capacity and 150V voltage rating minimum
• Mechanical Compatibility: Shrouded 4-wall design, square contact shape, solder termination with detent lock fastening
• Material & Environmental Compliance: Polyamide (PA) nylon insulation, UL94 V-0 flammability rating, operating range -35°C to 85°C

The DF13-3P-1.25DS(25) meets all substitution criteria as an active product within the same DF13 series, maintaining identical mechanical and electrical specifications while differing only in contact finish material and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The DF13-3P-1.25DS(25) is the direct substitute for the obsolete DF13-3P-1.25DS(77). Both components are manufactured by Hirose Electric Co Ltd within the same DF13 series and maintain identical mechanical and electrical specifications. The primary distinction is the contact finish material: the original part features gold plating, while the substitute uses tin plating. Both finishes are suitable for solder termination applications.

The DF13-3P-1.25DS(25) holds active product status with improved compliance certification (ROHS3 versus RoHS Compliant) and is currently available in higher inventory quantities (1219 units versus 984 units for the obsolete variant). The substitute is packaged in tube format and carries REACH Unaffected status, providing additional regulatory clarity for international applications.

Frequently Asked Questions (FAQ)

Q: Can the DF13-3P-1.25DS(25) be used as a direct replacement for the DF13-3P-1.25DS(77)?

A: Yes. Both connectors share identical mechanical dimensions, electrical ratings, mounting configuration, and contact geometry. The substitution is valid for all applications where the original part was specified.

Q: What is the difference between the gold and tin contact finishes?

A: The DF13-3P-1.25DS(77) features gold-plated contacts (30.0µin thickness), while the DF13-3P-1.25DS(25) uses tin plating. Both finishes are compatible with solder termination and provide adequate corrosion resistance for the specified operating temperature range of -35°C to 85°C.

Q: Does the packaging difference affect compatibility?

A: No. The DF13-3P-1.25DS(77) is supplied without specified packaging, while the DF13-3P-1.25DS(25) is packaged in tube format. Packaging affects only handling and storage procedures, not the connector's functional or mechanical performance.

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

A: The DF13-3P-1.25DS(25) carries ROHS3 Compliant certification and REACH Unaffected status, providing enhanced regulatory documentation compared to the original RoHS Compliant designation. Both parts maintain UL94 V-0 flammability rating and identical electrical specifications.

Q: What is the current availability status?

A: The DF13-3P-1.25DS(77) is listed as obsolete. The DF13-3P-1.25DS(25) is an active product with 1219 units in stock, making it the recommended procurement choice for new designs and ongoing production support.
