Substitute Part Grouping Explanation

Substitution of the DF13-7P-1.25DSA(75) is determined by strict equivalence across the following critical parameters:

• Series and Base Product Number: Both parts belong to the DF13 series
• Number of Positions: 7 positions maintained
• Pitch - Mating: 0.049" (1.25mm) pitch maintained
• Contact Type: Male pin configuration maintained
• Mounting Type: Through hole maintained
• Shrouding: Shrouded - 4 wall design maintained
• Electrical Ratings: 1A current and 150V voltage maintained
• Operating Temperature Range: -35°C ~ 85°C maintained
• Material Flammability: UL94 V-0 maintained
• Insulation Material: Polyamide (PA), Nylon maintained
• Contact Material: Brass maintained
• Contact Finish: Tin maintained

The primary distinction between the main part and its substitute is product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The DF13-7P-1.25DSA(25) is the direct functional equivalent for the obsolete DF13-7P-1.25DSA(75). Both parts maintain identical electrical and mechanical specifications across all critical parameters including pitch, position count, current and voltage ratings, operating temperature range, and flammability classification.

The DF13-7P-1.25DSA(25) carries active product status and is currently in stock, providing supply continuity for applications previously using the DF13-7P-1.25DSA(75). The substitute part meets ROHS3 compliance and carries an MSL rating of 1 (Unlimited), indicating superior moisture handling characteristics compared to the original part designation.

Packaging is supplied in tube format for the active equivalent, compared to the original part specification.

Frequently Asked Questions (FAQ)

Q: Can DF13-7P-1.25DSA(25) be used as a direct replacement for DF13-7P-1.25DSA(75)?

A: Yes. Both parts are functionally equivalent across all electrical and mechanical parameters. The connector maintains the same 7-position configuration, 0.049" (1.25mm) pitch, 1A current rating, 150V voltage rating, through-hole mounting, and shrouded 4-wall design.

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

A: The primary differences are product status and packaging. The DF13-7P-1.25DSA(75) is obsolete, while the DF13-7P-1.25DSA(25) is active. The substitute part is supplied in tube packaging and carries ROHS3 compliance with an MSL rating of 1 (Unlimited).

Q: Are there any compatibility concerns when substituting these parts?

A: No compatibility concerns exist. The parts are mechanically and electrically interchangeable within the same application context, maintaining identical mating pitch, contact configuration, and electrical performance specifications.

Q: What is the significance of the MSL rating difference?

A: The DF13-7P-1.25DSA(25) carries an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling, compared to the original part designation.
