Key Parameters

Substitute Part Grouping Explanation

The DF3EA-12P-2H(21) qualifies as a direct substitute for the DF3DZ-12P-2H(21) based on the following critical parameters:

• Connector Series: Both parts belong to the DF3 series from Hirose Electric Co Ltd
• Contact Configuration: Identical 12-position, male pin header design
• Pitch Specification: Both maintain 0.079" (2.00mm) mating pitch
• Mounting Method: Both are surface mount, right-angle connectors
• Shrouding Design: Both feature shrouded 4-wall construction
• Fastening Mechanism: Both utilize push-pull fastening
• Termination Type: Both use solder termination
• Operating Temperature Range: Both rated -55°C ~ 105°C
• Insulation Material: Both use Polyamide (PA), Nylon
• Insulation Height: Both measure 0.220" (5.60mm)
• Contact Material: Both use brass with tin finish
• Flammability Rating: Both meet UL94 V-0

The primary distinction is product status: DF3DZ-12P-2H(21) is obsolete while DF3EA-12P-2H(21) is active, with improved availability (2807 pcs in stock versus 994 pcs).
