Key Parameters

Substitute Part Grouping Explanation

The DF3EA-4P-2H(24) qualifies as a direct substitute based on the following critical parameters that determine functional compatibility:

• Identical connector type, contact type, and male pin configuration
• Matching 4-position, single-row layout with 2.00mm pitch
• Identical mounting method: surface mount, right-angle orientation
• Matching shrouding design: shrouded 4-wall construction
• Identical electrical ratings: 250VAC voltage, -55°C to 105°C operating temperature range
• Identical material specifications: brass contacts with tin finish, polyamide (PA) nylon insulation
• Matching flammability rating: UL94 V-0
• Identical fastening type: push-pull mechanism
• Identical termination method: solder

The primary difference is packaging format and product status, with the substitute part available in tube packaging and classified as Last Time Buy rather than obsolete.

Parameter Comparison

Engineering Selection Recommendations

The DF3EA-4P-2H(24) is the appropriate substitute for the obsolete DF3EA-4P-2H(20). All critical electrical, mechanical, and functional parameters are identical. The substitute part is available in higher inventory quantities and carries Last Time Buy status, providing better procurement accessibility than the obsolete original.

The DF3EA-4P-2H(24) includes RoHS compliance certification, which may be advantageous for applications subject to environmental regulations. The insulation color difference (black versus beige) is cosmetic and does not affect electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Are the DF3EA-4P-2H(20) and DF3EA-4P-2H(24) mechanically interchangeable?

A: Yes. Both connectors share identical mounting type (surface mount, right angle), pitch (2.00mm), position count (4), and shrouding design (4-wall). They mount identically on PCBs and mate with the same receptacle connectors.

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

A: The primary differences are packaging format and product lifecycle status. The DF3EA-4P-2H(24) is supplied in tube packaging and classified as Last Time Buy, while the DF3EA-4P-2H(20) is obsolete. The DF3EA-4P-2H(24) also includes RoHS compliance certification and features black insulation instead of beige.

Q: Can I use the DF3EA-4P-2H(24) in existing designs specified for the DF3EA-4P-2H(20)?

A: Yes. The electrical ratings (250VAC), operating temperature range (-55°C to 105°C), contact materials (brass with tin finish), and all functional specifications are identical. The substitute part is a direct replacement.

Q: Does the insulation color change affect performance?

A: No. Insulation color is a cosmetic attribute and does not impact electrical performance, mechanical fit, or thermal characteristics.

Q: What is the inventory status for the substitute part?

A: The DF3EA-4P-2H(24) is available in higher quantities (2109 pcs) compared to the original part (960 pcs) and is classified as Last Time Buy, indicating continued but limited availability.
