Engineering Selection Recommendations

The DF13-9P-1.25DSA(55) is the manufacturer-recommended substitute for the obsolete DF13-9P-1.25DSA(76). Both parts maintain identical electrical specifications, mechanical dimensions, and compliance certifications. The substitute part carries active product status, ensuring ongoing availability and supply chain continuity.

The primary difference between the two parts is the contact finish material on the post: the main part uses gold plating, while the substitute uses tin plating. Both finishes meet the specified electrical and mechanical requirements for this connector category. The substitute part also carries an MSL rating of 1 (Unlimited), indicating superior moisture handling characteristics compared to the main part's Not Applicable designation.

Both parts are RoHS compliant and carry identical ECCN and HTSUS classifications, supporting regulatory and trade compliance requirements.

Frequently Asked Questions (FAQ)

Q: Are DF13-9P-1.25DSA(76) and DF13-9P-1.25DSA(55) mechanically interchangeable?

A: Yes. Both connectors share identical mechanical dimensions, mounting type (through-hole), shrouding configuration (4-wall), and contact positioning. They are direct mechanical substitutes.

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

A: The main part uses gold plating on the post, while the substitute uses tin plating. Both finishes provide adequate electrical conductivity and corrosion resistance for this application. The choice between them depends on specific soldering process requirements and long-term reliability expectations in your application environment.

Q: Why is the main part marked as obsolete?

A: Product obsolescence is determined by the manufacturer based on production discontinuation. The substitute part DF13-9P-1.25DSA(55) remains in active production, making it the recommended choice for new designs and ongoing component procurement.

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

A: Both parts are RoHS compliant, carry identical UL94 V-0 flammability ratings, and share the same ECCN and HTSUS classifications. No compliance barriers exist for substitution.

Q: What does MSL 1 (Unlimited) mean on the substitute part?

A: MSL 1 indicates the component has unlimited shelf life under standard storage conditions without requiring baking before soldering. This represents superior moisture handling compared to the main part's Not Applicable designation.

Q: Can I use these connectors in high-temperature applications?

A: Both parts operate within the -35°C to 85°C temperature range. Applications requiring operation outside this range require alternative connector selection.
