DF3EA-2P-2H(20) Equivalent & Substitute Parts

Part Overview

The DF3EA-2P-2H(20) is a surface mount, right-angle rectangular connector header manufactured by Hirose Electric Co Ltd. This 2-position connector operates at 250VAC with a 2.00mm pitch and is designed for board-to-board or cable applications. The part is currently listed as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design and procurement requirements.

Key Parameters

Substitute Part Grouping Explanation

The DF3EA-2P-2H(24) qualifies as a direct substitute based on the following critical parameters:

• Same manufacturer (Hirose Electric Co Ltd) and base product number (DF3EA)
• Identical connector type, contact type, and number of positions (2-position header with male pins)
• Matching pitch specification (0.079" / 2.00mm)
• Identical mounting configuration (surface mount, right angle)
• Equivalent electrical ratings (250VAC, -55°C ~ 105°C operating range)
• Same material flammability rating (UL94 V-0)
• Identical shrouding design (shrouded - 4 wall) and fastening type (push-pull)
• Same contact material (brass) and finish (tin)

The primary difference is product status: DF3EA-2P-2H(24) is listed as Last Time Buy with RoHS compliance, whereas the main part is obsolete. Packaging differs (tube for the substitute versus unspecified for the main part).

Parameter Comparison

Engineering Selection Recommendations

The DF3EA-2P-2H(24) is the appropriate substitute for the obsolete DF3EA-2P-2H(20). Both parts share identical electrical and mechanical specifications, ensuring direct functional compatibility in existing designs. The substitute part carries RoHS compliance certification, providing regulatory advantage for new production runs. The Last Time Buy status of the substitute indicates limited availability; procurement planning should account for this constraint. Both parts maintain equivalent performance across all critical parameters including voltage rating, operating temperature range, and material flammability certification.

Frequently Asked Questions (FAQ)

Q: Are DF3EA-2P-2H(20) and DF3EA-2P-2H(24) mechanically interchangeable?

A: Yes. Both parts share identical mounting type (surface mount, right angle), pitch (2.00mm), number of positions (2), and shrouding configuration (shrouded - 4 wall). PCB footprints and mating interfaces are identical.

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

A: The primary differences are product status and packaging. DF3EA-2P-2H(20) is obsolete; DF3EA-2P-2H(24) is Last Time Buy with RoHS compliance and tube packaging. Electrical and mechanical specifications are identical.

Q: Can I use DF3EA-2P-2H(24) in place of DF3EA-2P-2H(20) in existing designs?

A: Yes. The substitute part meets all electrical and mechanical requirements of the original part. No design modifications are required.

Q: What does "Last Time Buy" status mean for DF3EA-2P-2H(24)?

A: Last Time Buy indicates the manufacturer will no longer produce this part after a specified date. Procurement should be completed within the available window to avoid future supply constraints.

Q: Are there any compliance differences between these parts?

A: DF3EA-2P-2H(24) is certified RoHS compliant, whereas RoHS status is not specified for DF3EA-2P-2H(20). Both parts carry UL94 V-0 flammability certification and operate within identical temperature and voltage ranges.

Q: Does packaging affect electrical performance?

A: No. Packaging (tube for the substitute) does not affect electrical or mechanical performance. It impacts only handling, storage, and logistics.
