Key Parameters

Substitute Part Grouping Explanation

The DF3E-3P-2V(24) qualifies as a direct substitute based on the following critical parameters that remain identical:

• Connector type, contact type, and fastening mechanism (Header, Male Pin, Push-Pull)
• Electrical specifications (250VAC voltage rating, -55°C ~ 105°C operating temperature)
• Physical dimensions and mating interface (3 positions, 2.00mm pitch, shrouded 4-wall construction)
• Material composition and flammability compliance (Brass contacts, Polyamide insulation, UL94 V-0)
• Contact finish specifications (Tin plating, 39.4µin thickness on mating surface)
• Moisture sensitivity level (MSL 1 - Unlimited)

The primary differences are packaging format (Tube vs. standard packaging) and insulation color (Black vs. Beige), which do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The DF3E-3P-2V(24) is a direct functional equivalent to the DF3E-3P-2V(20). Selection between these parts should be based on the following factors:

Product Status Consideration: The DF3E-3P-2V(20) is obsolete, while the DF3E-3P-2V(24) carries Last Time Buy status. For new designs or long-term production requirements, the DF3E-3P-2V(24) provides extended availability.

Compliance and Certification: Both parts maintain identical UL94 V-0 flammability ratings and RoHS compliance status (DF3E-3P-2V(24) explicitly confirmed as RoHS Compliant). Both are rated for identical electrical and thermal specifications.

Packaging and Inventory: The DF3E-3P-2V(24) is available in Tube packaging with significantly higher inventory (2329 Pcs vs. 763 Pcs), supporting higher-volume procurement requirements.

Visual Differentiation: The insulation color difference (Black vs. Beige) does not affect electrical or mechanical performance and may be relevant only for visual identification or assembly documentation purposes.

Frequently Asked Questions (FAQ)

Q: Can DF3E-3P-2V(24) be used as a direct replacement for DF3E-3P-2V(20) in existing designs?

A: Yes. All critical electrical, mechanical, and thermal parameters are identical. The parts are mechanically and electrically interchangeable. The insulation color difference and packaging format do not affect functional compatibility.

Q: What is the significance of the product status difference (Obsolete vs. Last Time Buy)?

A: Obsolete status indicates the DF3E-3P-2V(20) is no longer manufactured and existing inventory is limited. Last Time Buy status for the DF3E-3P-2V(24) indicates this is the final production run before discontinuation. For ongoing production, the DF3E-3P-2V(24) should be selected to ensure supply continuity.

Q: Does the insulation color change from Beige to Black affect performance?

A: No. Insulation color is a cosmetic attribute and does not impact electrical performance, thermal characteristics, or mechanical compatibility. Selection may depend on assembly documentation or visual identification requirements.

Q: Are both parts RoHS compliant?

A: The DF3E-3P-2V(24) is explicitly confirmed as RoHS Compliant. Both parts share identical material composition (Brass contacts, Polyamide insulation) and flammability ratings (UL94 V-0), supporting equivalent regulatory compliance.

Q: What is the difference between standard packaging and Tube packaging?

A: Tube packaging (DF3E-3P-2V(24)) provides organized component storage and handling for automated assembly processes. Standard packaging (DF3E-3P-2V(20)) refers to the original packaging format. Both formats contain identical components with no functional difference.

Q: Are the moisture sensitivity levels identical?

A: Yes. Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
