Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF3DZ-7P-2H(20) is determined by strict equivalence across the following critical parameters:

• Series Compatibility: Both parts belong to the DF3 series
• Connector Configuration: 7-position, single-row header with 0.079" (2.00mm) pitch
• Mounting and Orientation: Surface mount, right-angle configuration
• Mechanical Interface: Shrouded 4-wall construction with push-pull fastening
• Electrical Performance: Operating temperature range -55°C ~ 105°C, UL94 V-0 flammability rating
• Contact System: Male pin contacts with circular shape, brass material, tin finish

The DF3EA-7P-2H(51) meets all these criteria while offering active product status and enhanced specifications.

Parameter Comparison

Engineering Selection Recommendations

The DF3EA-7P-2H(51) is the direct active equivalent for the obsolete DF3DZ-7P-2H(20). Selection is based on the following engineering criteria:

Product Status: The DF3EA-7P-2H(51) carries active product status, ensuring continued availability, manufacturing support, and compliance with current regulatory requirements. The DF3DZ-7P-2H(20) is obsolete and subject to discontinuation.

Regulatory Compliance: The DF3EA-7P-2H(51) is RoHS Compliant, meeting current environmental and hazardous substance restrictions. Both parts maintain UL94 V-0 flammability rating and REACH Unaffected status.

Contact Finish Enhancement: The DF3EA-7P-2H(51) features gold-plated mating contacts (8.00µin / 0.203µm) compared to tin finish on the DF3DZ-7P-2H(20), providing improved corrosion resistance and contact reliability.

Packaging: The DF3EA-7P-2H(51) is supplied in Tape & Reel (TR) format, supporting automated assembly processes.

Mechanical and Electrical Equivalence: All critical parameters including connector configuration, pitch, mounting type, shrouding, fastening mechanism, operating temperature range, and flammability rating are identical between the two parts.

Frequently Asked Questions (FAQ)

Q: Can the DF3EA-7P-2H(51) be used as a direct replacement for the DF3DZ-7P-2H(20)?

A: Yes. Both connectors share identical mechanical and electrical specifications across all critical parameters: 7-position, 0.079" (2.00mm) pitch, surface mount right-angle configuration, shrouded 4-wall construction, push-pull fastening, and -55°C ~ 105°C operating temperature range. The DF3EA-7P-2H(51) is the active equivalent.

Q: What are the differences between these two parts?

A: The primary differences are product status, contact finish, and compliance certifications. The DF3EA-7P-2H(51) is active (versus obsolete), features gold-plated mating contacts (versus tin), is RoHS Compliant, and is supplied in Tape & Reel packaging. These differences represent enhancements rather than functional changes.

Q: Are there any compatibility concerns when substituting the DF3DZ-7P-2H(20) with the DF3EA-7P-2H(51)?

A: No compatibility concerns exist. Both parts are mechanically and electrically equivalent. The gold contact finish on the DF3EA-7P-2H(51) provides superior performance characteristics compared to tin finish.

Q: What is the significance of the contact finish difference?

A: The DF3EA-7P-2H(51) uses gold plating (8.00µin / 0.203µm) on mating contacts, which provides enhanced corrosion resistance and improved contact reliability compared to the tin finish on the DF3DZ-7P-2H(20). This is a performance enhancement.

Q: Does the packaging format affect electrical or mechanical performance?

A: No. Packaging format (Tape & Reel for the DF3EA-7P-2H(51)) affects only handling, storage, and assembly processes. Electrical and mechanical performance are identical.

Q: Are both parts compliant with current environmental regulations?

A: The DF3EA-7P-2H(51) is RoHS Compliant. Both parts maintain REACH Unaffected status and UL94 V-0 flammability rating. For new designs, the DF3EA-7P-2H(51) is recommended due to active RoHS compliance.
