Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF13-7P-1.25DSA(76) is determined by strict equivalence across the following critical parameters:

• Connector type (Header), contact type (Male Pin), and number of positions (7)
• Mating pitch (0.049" / 1.25mm) and mounting method (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall) and termination method (Solder)
• Electrical ratings: Current (1A), Voltage (150V), and operating temperature range (-35°C ~ 85°C)
• Material compliance: UL94 V-0 flammability rating and RoHS compliance

The DF13-7P-1.25DSA(55) meets all these criteria and is classified as an active product, making it a direct functional equivalent suitable for replacement applications.

Parameter Comparison

Engineering Selection Recommendations

The DF13-7P-1.25DSA(55) is the recommended substitute for the obsolete DF13-7P-1.25DSA(76). Both components are manufactured by Hirose Electric Co Ltd within the DF13 series and maintain identical mechanical and electrical specifications across all critical parameters. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

Both parts carry RoHS compliance certification and UL94 V-0 flammability rating, meeting regulatory requirements for industrial and consumer applications. The primary distinction between the two variants is the contact finish on the post termination: the main part uses gold plating while the substitute uses tin plating. This difference does not affect functional compatibility or electrical performance within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can DF13-7P-1.25DSA(55) be used as a direct replacement for DF13-7P-1.25DSA(76)?
