Substitute Part Grouping Explanation

The DF13A-9P-1.25H(21) qualifies as a direct substitute based on the following critical parameters:

• Connector Type & Contact Configuration: Both parts are headers with male pin contacts
• Position Count & Pitch: Identical 9-position configuration at 0.049" (1.25mm) mating pitch
• Mounting & Orientation: Both feature surface mount, right-angle mounting
• Electrical Ratings: Matching 1A current rating and 150V voltage rating
• Shrouding & Mechanical Design: Identical shrouded 4-wall construction
• Termination Method: Both use solder termination with detent lock fastening
• Environmental & Compliance: Matching operating temperature range (-35°C ~ 85°C), UL94 V-0 flammability rating, and RoHS compliance

The primary distinction is product status: DF13-9P-1.25H(21) is obsolete, while DF13A-9P-1.25H(21) is active with superior inventory availability.

Parameter Comparison

Frequently Asked Questions (FAQ)

Q: Are DF13-9P-1.25H(21) and DF13A-9P-1.25H(21) electrically interchangeable?

A: Yes. Both parts share identical electrical ratings (1A current, 150V voltage), operating temperature range (-35°C ~ 85°C), and contact configuration. They are direct electrical equivalents.

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

A: The primary difference is product status. DF13-9P-1.25H(21) is obsolete, while DF13A-9P-1.25H(21) is active. The substitute part includes improved packaging (Tape & Reel) and higher inventory availability. All functional and mechanical specifications remain identical.

Q: Can I use DF13A-9P-1.25H(21) as a drop-in replacement in existing designs?

A: Yes. The DF13A-9P-1.25H(21) maintains identical mechanical dimensions, mounting type (surface mount, right-angle), shrouding configuration (4-wall), and termination method (solder). No design modifications are required.

Q: Are there any compliance or certification differences?

A: No. Both parts are RoHS compliant and carry UL94 V-0 flammability certification. Moisture sensitivity level is identical (MSL 1 - Unlimited) for both parts.

Q: What packaging options are available?

A: DF13-9P-1.25H(21) packaging is not specified. DF13A-9P-1.25H(21) is supplied in Tape & Reel (TR) format, which is standard for surface mount production environments.
