Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF3Z-4P-2V(21) is determined by strict equivalence across the following critical parameters:

• Connector Series & Pitch: Both parts belong to the Hirose DF3 series with identical 2.00mm mating pitch
• Position Count & Configuration: 4-position, single-row header configuration maintained
• Mounting & Termination: Surface mount with solder termination required
• Shrouding & Fastening: Shrouded 4-wall construction with push-pull fastening mechanism
• Environmental & Compliance: Operating temperature range, UL94 V-0 flammability rating, and RoHS compliance must be maintained
• Moisture Sensitivity: MSL 1 rating preserved for unlimited shelf life

The DF3E-4P-2V(21) qualifies as a direct substitute based on these parameters. The primary distinction is product status: the DF3Z variant is discontinued, while the DF3E variant remains active in production.

Parameter Comparison

Engineering Selection Recommendations

The DF3E-4P-2V(21) is the direct equivalent for the discontinued DF3Z-4P-2V(21). Both parts maintain identical electrical and mechanical specifications, including connector pitch, position count, shrouding configuration, and operating temperature range. Both are RoHS compliant with UL94 V-0 flammability certification and MSL 1 moisture sensitivity rating.

The primary advantage of selecting the DF3E variant is active product status and availability. The DF3E-4P-2V(21) is supplied in Tape & Reel packaging, suitable for automated assembly processes. No design modifications or PCB layout changes are required for this substitution.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts are Hirose DF3 series headers with identical 4-position, 2.00mm pitch configuration, surface mount solder termination, and shrouded 4-wall construction. Electrical and mechanical compatibility is complete.

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

A: The DF3Z variant is discontinued. The DF3E variant is the active production equivalent with identical specifications. The DF3E is supplied in Tape & Reel packaging for high-volume automated assembly.

Q: Are there any PCB layout or assembly changes required when switching from DF3Z to DF3E?

A: No. Both parts share identical footprints, mating heights, and solder termination requirements. No PCB redesign is necessary.

Q: Do both parts meet the same compliance and environmental standards?

A: Yes. Both the DF3Z-4P-2V(21) and DF3E-4P-2V(21) are RoHS compliant, carry UL94 V-0 flammability certification, and operate across the -55°C to 105°C temperature range with MSL 1 moisture sensitivity rating.

Q: What packaging options are available for the substitute part?

A: The DF3E-4P-2V(21) is supplied in Tape & Reel (TR) packaging, standard for surface mount connector production and automated placement.
