Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF3DZ-6P-2H(73) is determined by strict equivalence across the following critical parameters:

• Connector series: DF3
• Number of positions: 6
• Pitch specification: 0.079" (2.00mm)
• Mounting configuration: Surface mount, right angle
• Shrouding design: Shrouded - 4 wall
• Contact type: Male pin
• Termination method: Solder
• Fastening mechanism: Push-pull
• Operating temperature range: -55°C ~ 105°C
• Material flammability: UL94 V-0
• RoHS compliance: Required

The DF3EA-6P-2H(51) meets all critical substitution criteria within the DF3 series, with the primary distinction being packaging format and contact finish specifications.

Parameter Comparison

Engineering Selection Recommendations

The DF3EA-6P-2H(51) is the direct substitute for the discontinued DF3DZ-6P-2H(73). Both parts maintain identical mechanical and electrical compatibility across all critical parameters: 6-position configuration, 2.00mm pitch, surface mount right-angle mounting, shrouded 4-wall design, and push-pull fastening.

The DF3EA-6P-2H(51) is currently active in production and available in Tape & Reel packaging. This part carries the same RoHS compliance, UL94 V-0 flammability rating, and unlimited moisture sensitivity level as the original part. The substitute includes gold-plated mating contacts with solder retention features, providing enhanced reliability for production environments.

Selection of the DF3EA-6P-2H(51) is appropriate for all applications previously served by the DF3DZ-6P-2H(73) without design modification.

Frequently Asked Questions (FAQ)

Q: Are the DF3DZ-6P-2H(73) and DF3EA-6P-2H(51) mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications: 6 positions, 2.00mm pitch, surface mount right-angle configuration, shrouded 4-wall design, and 0.220" insulation height. They are directly interchangeable in board-to-board and cable applications.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and packaging. The DF3DZ-6P-2H(73) is discontinued; the DF3EA-6P-2H(51) is active production. The DF3EA includes gold-plated mating contacts with 8.00µin thickness and solder retention features. The DF3EA is supplied in Tape & Reel packaging.

Q: Can I use the DF3EA-6P-2H(51) in place of the DF3DZ-6P-2H(73) without PCB redesign?

A: Yes. The DF3EA-6P-2H(51) maintains full mechanical and electrical compatibility. No PCB redesign is required.

Q: What is the current rating for the DF3EA-6P-2H(51)?

A: The current rating varies by wire gauge. The original DF3DZ-6P-2H(73) is rated at 3A.

Q: Are both parts RoHS compliant?

A: Yes. Both the DF3DZ-6P-2H(73) and DF3EA-6P-2H(51) are RoHS compliant with UL94 V-0 flammability rating and unlimited moisture sensitivity level.
