Key Parameters

Substitute Part Grouping Explanation

Substitution for the DF3Z-3P-2V(21) is determined by strict equivalence across the following critical parameters:

• Series Compatibility: Both parts belong to the Hirose DF3 series
• Position Count: Identical 3-position configuration
• Pitch Specification: Matching 0.079" (2.00mm) mating pitch
• Mounting Method: Surface mount technology maintained
• Shrouding Configuration: 4-wall shrouded design preserved
• Fastening Mechanism: Push-pull fastening type consistent
• Temperature Range: Operating range -55°C ~ 105°C maintained
• Flammability Rating: UL94 V-0 compliance retained
• RoHS Compliance: Environmental standards met

The DF3E-3P-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 with higher inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The DF3E-3P-2V(21) is the appropriate substitute for the discontinued DF3Z-3P-2V(21). Both parts maintain identical electrical and mechanical specifications across all critical parameters. The DF3E variant offers the advantage of active product status with significantly higher inventory availability (3622 pcs vs. 639 pcs). The DF3E achieves ROHS3 compliance, representing a more current environmental certification standard. Tape & Reel packaging for the DF3E variant supports automated assembly processes. No design modifications or board layout changes are required for this substitution.

Frequently Asked Questions (FAQ)

Q: Are the DF3Z-3P-2V(21) and DF3E-3P-2V(21) mechanically interchangeable?

A: Yes. Both connectors share identical pitch (2.00mm), position count (3), shrouding configuration (4-wall), and mounting type (surface mount). No PCB layout modifications are necessary.

Q: What is the primary reason for substitution?

A: The DF3Z-3P-2V(21) is discontinued at DiGi Electronics. The DF3E-3P-2V(21) provides equivalent functionality with active product status and improved supply availability.

Q: Do the operating temperature ranges differ?

A: No. Both parts operate across -55°C to 105°C, maintaining identical thermal performance specifications.

Q: What packaging differences exist between these parts?

A: The DF3Z-3P-2V(21) packaging is unspecified. The DF3E-3P-2V(21) is supplied in Tape & Reel (TR) format, which is standard for automated assembly operations.

Q: Are there compliance differences?

A: Both parts are RoHS compliant. The DF3E-3P-2V(21) carries ROHS3 certification, representing the current compliance standard. Both maintain UL94 V-0 flammability rating and MSL 1 moisture sensitivity level.

Q: Can these connectors be used in high-temperature applications?

A: Both parts are rated for continuous operation up to 105°C, suitable for standard industrial and consumer electronics applications within this temperature envelope.
