DF3Z-4P-2H(21) Equivalent & Substitute Parts

Part Overview

The DF3Z-4P-2H(21) is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for surface mount, right-angle board-to-board or cable applications. This shrouded 4-position connector operates at 0.079" (2.00mm) pitch with a 3A current rating and operates across -55°C to 105°C. The part is discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

The DF3E-4P-2H(21) qualifies as a direct substitute based on the following critical parameters that determine functional compatibility:

• Identical series designation (DF3)
• Matching connector type (Header) and contact type (Male Pin)
• Identical position count (4) and mating pitch (0.079" / 2.00mm)
• Identical mounting configuration (Surface Mount, Right Angle)
• Matching shrouding design (Shrouded - 4 Wall)
• Identical termination method (Solder)
• Identical operating temperature range (-55°C ~ 105°C)
• Matching material flammability rating (UL94 V-0)
• Identical RoHS compliance status

The primary distinction is product status: DF3Z-4P-2H(21) is discontinued, while DF3E-4P-2H(21) is active with higher inventory availability.

Frequently Asked Questions (FAQ)

Q: Can DF3E-4P-2H(21) be used as a direct replacement for DF3Z-4P-2H(21)?

A: Yes. Both parts are identical in electrical and mechanical specifications, including connector type, position count, mating pitch, mounting configuration, operating temperature range, and current rating. The primary difference is product status and packaging format.

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

A: The DF3Z-4P-2H(21) is discontinued, while DF3E-4P-2H(21) is an active product from the same DF3 series. Both share identical functional specifications and are interchangeable for board-to-board or cable applications.

Q: Are there packaging considerations when switching from DF3Z to DF3E?

A: DF3E-4P-2H(21) is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. DF3Z-4P-2H(21) packaging format is not specified in available data. Verify packaging requirements for your production environment.

Q: Do both parts meet the same compliance standards?

A: Yes. Both DF3Z-4P-2H(21) and DF3E-4P-2H(21) are RoHS Compliant, carry UL94 V-0 flammability rating, and share identical MSL (1 - Unlimited) and ECCN (EAR99) classifications.

Q: What is the current rating for these connectors?

A: DF3Z-4P-2H(21) has a specified current rating of 3A. DF3E-4P-2H(21) current rating varies by wire gauge. Consult detailed specifications for wire gauge-dependent current ratings when selecting DF3E-4P-2H(21).
