Frequently Asked Questions (FAQ)

Q: Are the DF13-2P-1.25DSA(75) and DF13-2P-1.25DSA(25) electrically identical?

A: Yes. Both parts maintain identical current rating (1A per contact), voltage rating (150V), operating temperature range (-35°C ~ 85°C), and contact material specifications (brass with tin finish).

Q: What is the difference between the two part numbers?

A: The primary difference is product status. The DF13-2P-1.25DSA(75) is obsolete, while the DF13-2P-1.25DSA(25) is active. The substitute part also reflects updated RoHS3 compliance classification and is supplied in tube packaging.

Q: Can the DF13-2P-1.25DSA(25) be used as a direct replacement in existing designs?

A: Yes. The substitute part is mechanically and electrically equivalent, with identical pitch (0.049" / 1.25mm), position count (2), mounting type (through hole), and termination method (solder).

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

A: Both parts meet UL94 V-0 flammability requirements and are classified under EAR99 export control. The substitute part carries ROHS3 compliance, representing an updated regulatory designation from the original RoHS Compliant status.

Q: What is the packaging difference?

A: The DF13-2P-1.25DSA(75) packaging is not specified. The DF13-2P-1.25DSA(25) is supplied in tube packaging, which is standard for component distribution and handling.
