Substitute Part Grouping Explanation

Substitution of the DF13-7P-1.25H(21) is based on strict equivalence of the following critical parameters:

• Connector Type & Contact Configuration: Header with male pins, 7 positions
• Pitch Specification: 0.049" (1.25mm) mating pitch
• Mounting & Orientation: Surface mount, right-angle configuration
• Electrical Ratings: 1A current rating, 150V voltage rating
• Mechanical Compatibility: Shrouded 4-wall design, solder termination with detent lock fastening
• Environmental & Compliance: Operating temperature range -35°C ~ 85°C, UL94 V-0 flammability rating, RoHS compliant, MSL 1

The substitute part DF13A-7P-1.25H(21) maintains all critical electrical and mechanical parameters. The primary difference is packaging format (Cut Tape vs. Tape & Reel) and product status (Obsolete vs. Active).

Parameter Comparison

Engineering Selection Recommendations

The DF13A-7P-1.25H(21) is the direct functional equivalent for the obsolete DF13-7P-1.25H(21). Both parts are manufactured by Hirose Electric Co Ltd and maintain identical electrical specifications, mechanical dimensions, and compliance certifications.

Product Status Consideration: The DF13-7P-1.25H(21) is obsolete, while the DF13A-7P-1.25H(21) maintains active product status. This distinction is significant for long-term supply chain planning and design continuity.

Compliance & Certification: Both parts are RoHS compliant, carry UL94 V-0 flammability rating, and maintain MSL 1 moisture sensitivity level. No compliance gaps exist between the two parts.

Packaging Difference: The primary distinction is packaging format. The original part is supplied in Cut Tape format, while the substitute is supplied in Tape & Reel format. This difference affects procurement quantities and handling but does not impact component functionality or performance.

Availability: The substitute part (DF13A-7P-1.25H(21)) demonstrates significantly higher inventory availability, supporting consistent procurement and production scheduling.

Frequently Asked Questions (FAQ)

Q: Are DF13-7P-1.25H(21) and DF13A-7P-1.25H(21) electrically identical?

A: Yes. Both parts have identical electrical ratings (1A current, 150V voltage), operating temperature range (-35°C ~ 85°C), and contact specifications (tin-plated brass, square shape).

Q: Can DF13A-7P-1.25H(21) be used as a direct replacement in existing designs?

A: Yes. The substitute part maintains identical mechanical dimensions, pitch (1.25mm), mounting type (surface mount right-angle), and connector configuration (7-position shrouded header). No PCB redesign or connector interface modification is required.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) packaging supplies components in smaller quantities on individual tape segments, suitable for lower-volume orders. Tape & Reel (TR) packaging supplies components on continuous reels, optimized for high-volume automated assembly. Both formats contain identical components; the difference is in handling and procurement quantity.

Q: Why is the original part listed as obsolete?

A: Product obsolescence typically reflects manufacturer decisions regarding production continuation. The DF13A variant remains in active production, providing a direct path for design continuity and supply chain management.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical certifications: RoHS compliant, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity level. No additional testing or qualification is required for substitution.

Q: What is the mating pitch, and why is it important for substitution?

A: The mating pitch is 0.049" (1.25mm), which defines the spacing between connector positions. This specification must remain identical for mechanical compatibility with mating connectors and PCB layouts. Both parts maintain this specification.
