Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF3DZ-7P-2V(21) is determined by strict equivalence across the following critical parameters:

• Manufacturer series consistency (DF3 series)
• Identical connector type, contact type, and position count (Header, Male Pin, 7 positions)
• Matching pitch specification (2.00mm)
• Identical shrouding configuration (Shrouded - 4 Wall)
• Matching mounting type (Surface Mount)
• Identical fastening mechanism (Push-Pull)
• Equivalent termination method (Solder)
• Compliance with material flammability standards (UL94 V-0)

The DF3EA-7P-2V(21) meets all substitution criteria as an active product within the DF3 series, providing direct functional and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The DF3EA-7P-2V(21) is the direct active substitute for the discontinued DF3DZ-7P-2V(21). Both parts maintain identical mechanical and electrical interface specifications, ensuring pin-for-pin compatibility in board-level applications.

The DF3EA-7P-2V(21) provides enhanced compliance status (ROHS3 Compliant versus RoHS Compliant) and an extended operating temperature range (-55°C ~ 105°C versus -30°C ~ 85°C), making it suitable for applications requiring broader environmental performance. The substitute part is available in Tape & Reel packaging, supporting high-volume production requirements.

Selection of the DF3EA-7P-2V(21) is appropriate for new designs and production continuity where the DF3DZ-7P-2V(21) is no longer available.

Frequently Asked Questions (FAQ)

Q: Are the DF3DZ-7P-2V(21) and DF3EA-7P-2V(21) mechanically interchangeable?

A: Yes. Both connectors share identical pitch (2.00mm), position count (7), shrouding configuration (4-wall), and mounting type (surface mount), ensuring direct mechanical compatibility in PCB layouts.

Q: What is the primary difference between these two parts?

A: The DF3EA-7P-2V(21) is an active product with extended operating temperature range (-55°C ~ 105°C) and updated RoHS3 compliance, whereas the DF3DZ-7P-2V(21) is discontinued with a narrower operating range (-30°C ~ 85°C).

Q: Can the DF3EA-7P-2V(21) be used in applications originally designed for the DF3DZ-7P-2V(21)?

A: Yes, provided the application's operating temperature requirements fall within the DF3EA-7P-2V(21) specification range. The extended temperature capability of the substitute part does not create compatibility issues.

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

A: The DF3EA-7P-2V(21) is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.

Q: Are there any electrical parameter differences between these connectors?

A: Both parts maintain identical contact material (brass), contact finish (tin), and solder retention features. The DF3EA-7P-2V(21) specifies current rating as "Varies by Wire Gauge" and includes a 250VAC voltage rating, providing additional electrical specification clarity for design applications.
