Key Parameters

Substitute Part Grouping Explanation

The DF3EA-9P-2H(21) qualifies as a direct substitute based on the following critical parameters:

• Connector Series: Both parts belong to the DF3 series from Hirose Electric Co Ltd
• Position Count & Pitch: Identical 9-position configuration with 0.079" (2.00mm) mating pitch
• Mounting & Orientation: Both are surface mount, right-angle headers
• Shrouding Configuration: Both feature shrouded 4-wall design
• Contact Type & Material: Both use male pin contacts with brass material and tin finish
• Insulation Material & Color: Both use polyamide (PA) nylon with beige insulation
• Electrical & Environmental Ratings: Both operate across -55°C ~ 105°C and maintain UL94 V-0 flammability rating
• Compliance: Both are RoHS compliant with MSL 1 (Unlimited)

The primary distinction is product status: DF3DZ-9P-2H(21) is discontinued, while DF3EA-9P-2H(21) is active with current inventory availability.

Frequently Asked Questions (FAQ)

Q: Can DF3EA-9P-2H(21) be used as a direct replacement for DF3DZ-9P-2H(21)?

A: Yes. Both connectors share identical electrical and mechanical specifications, including 9-position configuration, 2.00mm pitch, surface mount right-angle mounting, and operating temperature range of -55°C to 105°C. The primary difference is product status: DF3EA-9P-2H(21) is active with current availability.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution is based on matching connector series (DF3), position count (9), mating pitch (2.00mm), mounting type (surface mount right-angle), shrouding configuration (4-wall), contact type (male pin), and operating temperature range (-55°C ~ 105°C).

Q: Does packaging differ between these parts?

A: Yes. DF3DZ-9P-2H(21) packaging is not specified, while DF3EA-9P-2H(21) is supplied in Tape & Reel (TR) format, which is standard for automated surface mount assembly.

Q: Are both parts RoHS compliant?

A: Yes. Both DF3DZ-9P-2H(21) and DF3EA-9P-2H(21) are RoHS compliant with MSL 1 (Unlimited) moisture sensitivity level.

Q: What is the current rating for these connectors?

A: The DF3DZ-9P-2H(21) is rated at 3A. The DF3EA-9P-2H(21) current rating varies by wire gauge.
