Key Parameters

Substitute Part Grouping Explanation

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

• Identical connector type, contact type, and male pin configuration
• Matching pitch specification of 0.079" (2.00mm)
• Identical number of positions (2) and row configuration (1 row)
• Identical mounting type (Surface Mount) and shrouding design (Shrouded - 4 Wall)
• Matching termination method (Solder) and fastening type (Push-Pull)
• Identical voltage rating (250VAC) and operating temperature range (-55°C ~ 105°C)
• Identical material flammability rating (UL94 V-0)
• Same base product number (DF3) and series designation (DF3)
• Identical MSL classification (1 - Unlimited)

The primary distinction is product status: DF3E-2P-2V(50) is Obsolete, while DF3E-2P-2V(54) is Last Time Buy with significantly higher inventory availability (4790 Pcs vs 783 Pcs).

Parameter Comparison

Engineering Selection Recommendations

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

Product Status Consideration: DF3E-2P-2V(50) carries Obsolete status, indicating end-of-life classification. DF3E-2P-2V(54) is designated Last Time Buy, providing a defined procurement window before discontinuation.

Compliance and Certification: Both parts meet identical electrical and mechanical specifications, including UL94 V-0 flammability rating and MSL 1 classification. DF3E-2P-2V(54) includes explicit RoHS Compliance certification.

Inventory Availability: DF3E-2P-2V(54) offers substantially higher stock levels (4790 Pcs vs 783 Pcs), supporting extended production runs and supply chain continuity.

Physical Differentiation: Insulation color differs (Beige vs Black) and packaging is specified as Tube for DF3E-2P-2V(54). These are cosmetic and logistical variations with no impact on electrical or mechanical function.

Frequently Asked Questions (FAQ)

Q: Are DF3E-2P-2V(50) and DF3E-2P-2V(54) electrically interchangeable?

A: Yes. Both parts share identical electrical specifications including 250VAC voltage rating, operating temperature range (-55°C ~ 105°C), contact material (Brass with Gold finish), and current rating variation by wire gauge. They are direct electrical equivalents.

Q: What is the significance of the different insulation colors (Beige vs Black)?

A: Insulation color is a cosmetic specification with no functional impact on connector performance. Selection between Beige and Black is determined by design aesthetics or internal documentation requirements only.

Q: Does the packaging difference (unspecified vs Tube) affect compatibility?

A: No. Packaging format affects logistics and handling only. The connector itself is identical regardless of whether it arrives in Tube packaging or alternative formats. Packaging does not influence electrical or mechanical function.

Q: Why is DF3E-2P-2V(54) marked as Last Time Buy while DF3E-2P-2V(50) is Obsolete?

A: Last Time Buy designation indicates a defined final procurement period before manufacturer discontinuation. Obsolete status indicates the part has already reached end-of-life. DF3E-2P-2V(54) provides a transition path for designs currently using DF3E-2P-2V(50).

Q: Is RoHS compliance a functional requirement for substitution?

A: RoHS compliance is a regulatory and environmental specification. DF3E-2P-2V(54) explicitly states RoHS Compliance. If RoHS compliance is mandated by your application or regional requirements, DF3E-2P-2V(54) satisfies this requirement. DF3E-2P-2V(50) does not specify RoHS status.

Q: Can I use DF3E-2P-2V(54) as a direct replacement in existing PCB designs?

A: Yes. Identical pitch (2.00mm), mounting type (Surface Mount), position count (2), and mechanical envelope ensure direct PCB footprint compatibility. No design modification is required.
