Key Parameters

Substitute Part Grouping Explanation

The DF3EA-4P-2H(21) qualifies as a direct substitute based on the following critical parameters that determine functional compatibility:

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

The primary distinction is product status: DF3DZ-4P-2H(75) is discontinued, while DF3EA-4P-2H(21) is active with significantly higher inventory availability (20,974 pcs vs. 759 pcs).

Frequently Asked Questions (FAQ)

Q: Are DF3DZ-4P-2H(75) and DF3EA-4P-2H(21) electrically interchangeable?

A: Yes. Both connectors share identical electrical specifications including 3A current rating, operating temperature range (-55°C ~ 105°C), and contact material (brass). They are functionally equivalent for all electrical applications.

Q: What are the mechanical differences between these parts?

A: There are no functional mechanical differences. Both feature 4-position, 0.079" (2.00mm) pitch, surface mount right-angle configuration with shrouded 4-wall design and solder termination.

Q: Why does the substitute part have different packaging?

A: DF3EA-4P-2H(21) is supplied in Tape & Reel (TR) packaging, which is standard for active production parts and optimized for automated assembly. The original DF3DZ-4P-2H(75) packaging information was not specified. This packaging difference does not affect electrical or mechanical compatibility.

Q: Is the RoHS3 compliance of the substitute part compatible with RoHS applications?

A: Yes. ROHS3 compliance is an enhanced version of RoHS compliance and is fully backward compatible. Applications requiring RoHS Compliant components can use ROHS3 Compliant substitutes without restriction.

Q: Can I use DF3EA-4P-2H(21) in existing designs specified for DF3DZ-4P-2H(75)?

A: Yes. The substitute part maintains identical form factor, pin configuration, pitch, and electrical ratings. No design modifications are required for direct substitution in PCB layouts or cable assemblies.

Q: What is the moisture sensitivity level, and does it affect handling?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling procedures apply without special moisture control requirements.
