Key Parameters

Substitute Part Grouping Explanation

Substitution for the DF3Z-2P-2H(21) is based on strict equivalence across the following critical parameters:

• Series alignment within DF3 family
• Identical connector type (Header) and contact type (Male Pin)
• Matching position count (2 positions) and mating pitch (2.00mm)
• Identical mounting configuration (Surface Mount, Right Angle)
• Matching shrouding design (Shrouded - 4 Wall)
• Equivalent termination method (Solder)
• Identical fastening type (Push-Pull)
• Operating temperature range compatibility (-55°C ~ 105°C)
• Equivalent material flammability rating (UL94 V-0)
• RoHS compliance status

The DF3E-2P-2H(21) qualifies as a direct substitute based on these parameters, with the primary distinction being packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The DF3E-2P-2H(21) offers the advantage of active product status with higher inventory availability (5664 pcs vs. 711 pcs), ensuring supply chain continuity. The DF3E variant includes ROHS3 compliance certification, providing enhanced regulatory coverage. Packaging is supplied in Tape & Reel format, suitable for automated assembly processes. No functional or performance differences exist between these parts for equivalent applications.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts are identical in connector type, position count, mating pitch, mounting configuration, shrouding design, termination method, and operating specifications. The DF3E variant is the active production equivalent.

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

A: The DF3Z and DF3E are both members of the DF3 series from Hirose Electric. The DF3E represents the current production variant, while the DF3Z is discontinued. Functionally and mechanically, they are equivalent for this 2-position configuration.

Q: Does packaging format affect compatibility?

A: Packaging format (Tape & Reel vs. bulk) does not affect electrical or mechanical compatibility. The DF3E-2P-2H(21) is supplied in Tape & Reel format, which is standard for automated assembly. Component functionality remains identical.

Q: Are there any compliance differences between the two parts?

A: Both parts are RoHS compliant. The DF3E-2P-2H(21) carries ROHS3 certification, providing updated regulatory alignment. Both maintain UL94 V-0 flammability rating and MSL 1 moisture sensitivity level.

Q: What is the current availability status?

A: The DF3Z-2P-2H(21) is discontinued at DiGi Electronics with 711 pcs remaining in stock. The DF3E-2P-2H(21) is active with 5664 pcs in stock, ensuring reliable supply for new designs and production runs.
