Key Parameters

Substitute Part Grouping Explanation

The DF3E-4P-2V(54) qualifies as a direct substitute based on the following critical parameters:

• Connector Series & Type: Both parts belong to the DF3 series and function as shrouded 4-wall header connectors
• Electrical Specifications: Identical pitch (2.00mm), position count (4), contact type (male pin), voltage rating (250VAC), and operating temperature range (-55°C ~ 105°C)
• Mechanical Configuration: Both feature surface mount termination, push-pull fastening, and identical insulation height (5.90mm)
• Material & Compliance: Both use brass contacts with gold finish, polyamide/nylon insulation, and UL94 V-0 flammability rating
• Moisture Sensitivity: Both rated MSL 1 (Unlimited)

The primary distinction is packaging format and product status: DF3E-4P-2V(50) is Obsolete with beige insulation, while DF3E-4P-2V(54) is Last Time Buy with black insulation and Tube packaging.

Parameter Comparison

Engineering Selection Recommendations

The DF3E-4P-2V(54) is the direct functional equivalent for DF3E-4P-2V(50) applications. Selection between these parts should be based on the following factors:

Product Status Consideration: DF3E-4P-2V(50) is Obsolete, indicating discontinued manufacturing and limited availability. DF3E-4P-2V(54) carries Last Time Buy status, providing a defined procurement window before full discontinuation.

Compliance & Certification: Both parts meet UL94 V-0 flammability requirements and carry identical electrical and mechanical specifications. DF3E-4P-2V(54) explicitly documents RoHS Compliance, providing additional regulatory assurance for new designs.

Physical Differentiation: Insulation color differs (Beige vs. Black). This distinction is cosmetic and does not affect electrical or mechanical performance. Packaging format differs (unspecified vs. Tube), which may impact procurement logistics but not functional compatibility.

Inventory & Availability: DF3E-4P-2V(54) shows higher inventory availability (1296 Pcs) compared to DF3E-4P-2V(50) (949 Pcs), supporting procurement reliability.

Frequently Asked Questions (FAQ)

Q: Can DF3E-4P-2V(54) directly replace DF3E-4P-2V(50) in existing designs?

A: Yes. Both parts share identical electrical ratings (250VAC), mechanical dimensions (4-position, 2.00mm pitch, 5.90mm insulation height), contact configuration (male pin, circular, gold-plated brass), and operating temperature range (-55°C ~ 105°C). The connector type, shrouding style (4-wall), fastening mechanism (push-pull), and termination method (solder) are identical.

Q: What is the significance of the insulation color difference?

A: Insulation color (Beige vs. Black) is a visual identifier only and does not affect electrical performance, mechanical fit, or functional compatibility. Selection may be based on design aesthetics or internal documentation standards.

Q: Why does DF3E-4P-2V(54) specify RoHS Compliance while DF3E-4P-2V(50) does not?

A: DF3E-4P-2V(50) is classified as Obsolete, predating comprehensive RoHS documentation practices. DF3E-4P-2V(54), classified as Last Time Buy, includes explicit RoHS Compliance certification, reflecting current regulatory documentation standards.

Q: Does packaging format affect connector performance?

A: No. Packaging format (Tube for DF3E-4P-2V(54)) affects handling, storage, and procurement logistics but does not influence electrical or mechanical performance. Both parts are functionally identical when installed.

Q: Are there any temperature or voltage limitations when substituting these parts?

A: No. Both parts operate identically across the full temperature range (-55°C ~ 105°C) and voltage rating (250VAC). Electrical and thermal performance characteristics are equivalent.
