Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF3Z-2P-2V(21) is determined by strict alignment of the following critical parameters:

• Series Compatibility: Both parts must belong to the DF3 series
• Connector Configuration: 2-position header with male pin contacts
• Pitch Specification: 0.079" (2.00mm) mating pitch
• Mounting Method: Surface mount technology
• Shrouding Design: Shrouded - 4 wall construction
• Termination Type: Solder termination
• Fastening Mechanism: Push-pull fastening
• Temperature Range: -55°C ~ 105°C operating window
• Flammability Standard: UL94 V-0 rating
• Insulation Material: Polyamide (PA), Nylon
• Contact Material: Brass with tin finish

The DF3E-2P-2V(21) meets all these criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The DF3E-2P-2V(21) is the direct substitute for the discontinued DF3Z-2P-2V(21). Both connectors share identical electrical and mechanical specifications across all critical parameters. The DF3E-2P-2V(21) offers the advantage of active product status with confirmed inventory availability (8774 Pcs New Original In Stock), ensuring supply chain continuity. The DF3E variant includes standardized Tape & Reel packaging suitable for automated assembly processes. Both parts maintain equivalent RoHS compliance and REACH status, with the DF3E meeting ROHS3 standards. No design modifications are required for substitution.

Frequently Asked Questions (FAQ)

Q: Can the DF3E-2P-2V(21) be used as a direct replacement for the DF3Z-2P-2V(21)?

A: Yes. Both connectors are identical in electrical and mechanical specifications, including pitch, position count, shrouding design, termination method, and operating temperature range. The DF3E-2P-2V(21) is the active equivalent.

Q: What is the difference between the DF3Z and DF3E variants?

A: The primary difference is product status. The DF3Z-2P-2V(21) is discontinued, while the DF3E-2P-2V(21) is active. The DF3E is supplied in Tape & Reel packaging, which is standard for production environments. All functional and electrical parameters are identical.

Q: Are there any compatibility concerns when switching from DF3Z to DF3E?

A: No compatibility concerns exist. The connectors are mechanically and electrically interchangeable. PCB footprints, mating interfaces, and electrical performance remain unchanged.

Q: What is the current rating for these connectors?

A: The DF3Z-2P-2V(21) is rated at 3A. The DF3E-2P-2V(21) current rating varies by wire gauge. Verify wire gauge specifications for your application to confirm current capacity.

Q: Are both parts RoHS compliant?

A: Yes. The DF3Z-2P-2V(21) is RoHS Compliant. The DF3E-2P-2V(21) meets ROHS3 Compliant standards, which represents an updated compliance certification.

Q: What is the moisture sensitivity level for these connectors?

A: Both connectors have a Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
