Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF3E-4P-2V(20) is based on strict electrical and mechanical parameter matching within the DF3 series. The substitute part DF3E-4P-2V(24) maintains identical specifications across all critical parameters: 4-position configuration, 2.00mm pitch, surface mount technology, 250VAC voltage rating, -55°C to 105°C operating temperature range, and UL94 V-0 flammability compliance. Both parts share the same connector type (Header), contact material (Brass with Tin finish), shrouding design (Shrouded - 4 Wall), and fastening mechanism (Push-Pull). The substitution is valid based on these matching electrical and mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The DF3E-4P-2V(24) is a direct functional equivalent to the DF3E-4P-2V(20) for all electrical and mechanical applications. Both parts meet identical voltage, temperature, and flammability requirements. The primary distinction is product lifecycle status: the DF3E-4P-2V(20) is Obsolete, while the DF3E-4P-2V(24) carries Last Time Buy status, indicating extended availability for procurement. The DF3E-4P-2V(24) includes RoHS Compliance certification, providing regulatory advantage for applications subject to RoHS requirements. Insulation color differs (Beige versus Black), which does not affect electrical or mechanical performance. The DF3E-4P-2V(24) is the appropriate selection for new designs and ongoing production requiring this connector specification.

Frequently Asked Questions (FAQ)

Q: Are DF3E-4P-2V(20) and DF3E-4P-2V(24) electrically interchangeable?

A: Yes. Both parts share identical electrical specifications: 250VAC voltage rating, -55°C to 105°C operating temperature range, and equivalent contact materials and finishes. They are electrically interchangeable in all applications.

Q: What is the significance of the different product status designations?

A: DF3E-4P-2V(20) is classified as Obsolete, indicating discontinued production. DF3E-4P-2V(24) is Last Time Buy status, meaning limited future availability. For new designs, DF3E-4P-2V(24) is the recommended selection due to extended procurement window.

Q: Does the insulation color difference affect compatibility?

A: No. Insulation color is a cosmetic parameter and does not affect electrical performance, mechanical fit, or functional compatibility. Both Beige and Black insulation materials are identical polyamide (PA) nylon compositions.

Q: What is the mechanical compatibility between these parts?

A: Both parts are mechanically identical. They share the same 4-position configuration, 2.00mm pitch, surface mount footprint, shrouded design, and push-pull fastening mechanism. PCB layouts and mating connectors are fully compatible.

Q: Is RoHS compliance a factor in selecting between these parts?

A: DF3E-4P-2V(24) is explicitly RoHS Compliant, while DF3E-4P-2V(20) compliance status is not specified. For applications requiring RoHS certification, DF3E-4P-2V(24) is the appropriate choice.

Q: Are there packaging differences between these parts?

A: DF3E-4P-2V(20) packaging is not specified. DF3E-4P-2V(24) is supplied in Tube packaging. Packaging format does not affect component performance or compatibility.
