Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF13-2P-1.25DSA(76) is determined by strict equivalence across the following critical parameters:

• Connector series and base product number (DF13)
• Number of positions (2)
• Pitch specification (0.049" / 1.25mm)
• Contact type and gender (Male Pin)
• Mounting method (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall)
• Electrical ratings (1A current, 150V voltage)
• Operating temperature range (-35°C ~ 85°C)
• Material compliance (UL94 V-0, RoHS Compliant)

The DF13-2P-1.25DSA(55) meets all these criteria and is classified as an active product, making it a direct functional equivalent suitable for replacement in applications currently using the obsolete DF13-2P-1.25DSA(76).

Parameter Comparison

Engineering Selection Recommendations

The DF13-2P-1.25DSA(55) is the appropriate substitute for the obsolete DF13-2P-1.25DSA(76). Both parts maintain identical electrical and mechanical specifications across all critical parameters, including pitch, position count, current and voltage ratings, operating temperature range, and material compliance certifications.

The primary distinction between these parts is product status and contact post finish. The DF13-2P-1.25DSA(76) is obsolete with gold-plated posts, while the DF13-2P-1.25DSA(55) is an active product with tin-plated posts. Both finishes are compatible with standard solder termination processes and meet the same UL94 V-0 flammability and RoHS compliance requirements.

Selection of the DF13-2P-1.25DSA(55) ensures continued availability and supply chain support for applications currently specified with the DF13-2P-1.25DSA(76).

Frequently Asked Questions (FAQ)

Q: Can the DF13-2P-1.25DSA(55) be used as a direct replacement for the DF13-2P-1.25DSA(76)?

A: Yes. Both parts are identical in connector type, position count, pitch, electrical ratings, and mounting configuration. The DF13-2P-1.25DSA(55) is the active equivalent and suitable for direct substitution.

Q: What is the difference between the contact post finishes?

A: The DF13-2P-1.25DSA(76) features gold-plated posts, while the DF13-2P-1.25DSA(55) features tin-plated posts. Both finishes are compatible with solder termination and provide equivalent electrical performance in this application.

Q: Are there any compatibility concerns with PCB layouts or mating connectors?

A: No. The DF13-2P-1.25DSA(55) maintains identical mechanical dimensions, pitch spacing, and shrouding configuration. Existing PCB layouts and mating connectors designed for the DF13-2P-1.25DSA(76) are fully compatible.

Q: Why is the DF13-2P-1.25DSA(76) listed as obsolete?

A: The DF13-2P-1.25DSA(76) has been superseded by the DF13-2P-1.25DSA(55) in the manufacturer's active product line. The DF13-2P-1.25DSA(55) provides equivalent functionality with improved supply chain availability.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the DF13-2P-1.25DSA(76) and DF13-2P-1.25DSA(55) are RoHS Compliant, carry UL94 V-0 material flammability ratings, and share identical ECCN and HTSUS classifications.
