Key Parameters

Substitute Part Grouping Explanation

The DF3E-8P-2V(21) qualifies as a direct substitute based on the following critical parameters that determine functional equivalence:

• Series alignment: Both parts belong to the DF3 series
• Connector configuration: 8-position header with 2.00mm pitch
• Mounting method: Surface mount technology
• Mechanical design: Shrouded 4-wall construction with push-pull fastening
• Environmental compliance: UL94 V-0 flammability rating, RoHS compliant, MSL 1
• Operating temperature range: -55°C ~ 105°C
• Contact material and finish: Brass with tin plating
• Insulation material: Polyamide (PA), Nylon
• Termination method: Solder

The primary distinction is product status: the DF3Z variant is discontinued, while the DF3E variant remains active with higher inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The DF3E-8P-2V(21) is the direct equivalent for the discontinued DF3Z-8P-2V(21). Both parts maintain identical electrical and mechanical specifications, including connector configuration, operating temperature range, and compliance certifications. The DF3E variant is currently in active production status with higher inventory availability (2154 pcs vs. 881 pcs), making it the preferred selection for new designs and component replenishment. Both parts satisfy RoHS compliance and UL94 V-0 flammability requirements for equivalent application contexts.

Frequently Asked Questions (FAQ)

Q: Can the DF3E-8P-2V(21) be used as a direct replacement for the DF3Z-8P-2V(21)?

A: Yes. Both connectors share identical electrical and mechanical specifications, including 8-position configuration, 2.00mm pitch, surface mount design, and operating temperature range. The primary difference is product status and packaging format.

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

A: The DF3Z is discontinued, while the DF3E remains in active production. Both belong to the DF3 series and maintain the same connector specifications. The DF3E is supplied in Tape & Reel packaging, whereas the DF3Z packaging format is not specified.

Q: Are there any compatibility concerns when substituting these parts?

A: No compatibility concerns exist. Both parts feature identical shrouded 4-wall construction, push-pull fastening, solder termination, and contact materials. PCB footprints and mating interface specifications are equivalent.

Q: What certifications apply to both parts?

A: Both the DF3Z-8P-2V(21) and DF3E-8P-2V(21) are RoHS compliant, carry UL94 V-0 flammability rating, and have MSL 1 (Unlimited) moisture sensitivity classification.

Q: Are there any current rating differences?

A: The DF3Z-8P-2V(21) specifies 3A current rating. The DF3E-8P-2V(21) current rating varies by wire gauge. Verify wire gauge requirements for your specific application to ensure adequate current capacity.
