Key Parameters

Substitute Part Grouping Explanation

The DF3EA-2P-2H(51) qualifies as a direct substitute based on the following critical parameters that determine functional compatibility:

• Identical series designation (DF3)
• Matching connector type (Header) and contact type (Male Pin)
• Identical number of positions (2) and mating pitch (0.079" / 2.00mm)
• Identical mounting configuration (Surface Mount, Right Angle)
• Matching shrouding design (Shrouded - 4 Wall)
• Identical termination method (Solder) and fastening type (Push-Pull)
• Identical operating temperature range (-55°C ~ 105°C)
• Matching material flammability rating (UL94 V-0)
• Identical moisture sensitivity level (MSL 1)

The substitute part maintains all core electrical and mechanical parameters required for direct replacement in the DF3 series connector family.

Parameter Comparison

Engineering Selection Recommendations

The DF3EA-2P-2H(51) is the appropriate substitute for the discontinued DF3DZ-2P-2H(73). Both parts maintain identical core specifications across all critical electrical and mechanical parameters. The substitute part carries active product status with confirmed inventory availability (27,430 pcs), ensuring supply chain continuity.

The DF3EA-2P-2H(51) meets ROHS3 compliance, which supersedes the RoHS compliance of the original part, providing enhanced regulatory alignment. The substitute includes solder retention features and gold contact finish (8.00µin / 0.203µm), which are enhancements over the original specification. Packaging is provided in Tape & Reel format, suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can DF3EA-2P-2H(51) be used as a direct replacement for DF3DZ-2P-2H(73)?

A: Yes. Both parts share identical connector type, position count, mating pitch, mounting configuration, and operating parameters. The substitute maintains full mechanical and electrical compatibility within the DF3 series.

Q: What are the key differences between these parts?

A: The primary differences are product status (active vs. discontinued), packaging format (Tape & Reel vs. unspecified), and contact finish specifications. The substitute includes gold plating on mating contacts and solder retention features, which are functional enhancements.

Q: Does the gold contact finish on DF3EA-2P-2H(51) affect compatibility?

A: No. Gold plating is a contact finish enhancement that improves corrosion resistance and contact reliability. It does not affect mechanical fit or electrical performance in this application.

Q: Are there any compliance differences?

A: The substitute carries ROHS3 compliance, which represents current regulatory standards and supersedes the RoHS compliance of the original part. Both parts maintain UL94 V-0 flammability rating and MSL 1 moisture sensitivity level.

Q: What is the impact of Tape & Reel packaging?

A: Tape & Reel packaging is standard for automated surface mount assembly. If manual assembly or alternative packaging is required, contact the manufacturer for alternative packaging options within the DF3 series.
