DF3E-3P-2V(50) Equivalent & Substitute Parts

Part Overview

The DF3E-3P-2V(50) is a surface mount rectangular connector header manufactured by Hirose Electric Co Ltd, designed for board-to-board or cable applications. This 3-position connector operates at 250VAC with a 2.00mm pitch and features shrouded 4-wall construction with solder termination and push-pull fastening. The part is currently marked as obsolete, making equivalent substitutes necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

The DF3E-3P-2V(54) qualifies as a direct substitute for the DF3E-3P-2V(50) based on the following critical parameters:

• Identical manufacturer (Hirose Electric Co Ltd) and series (DF3)
• Matching connector type, contact type, and number of positions (3)
• Identical pitch specification (0.079" / 2.00mm)
• Identical mounting type (Surface Mount), shrouding (Shrouded - 4 Wall), and termination method (Solder)
• Identical fastening type (Push-Pull)
• Matching voltage rating (250VAC) and operating temperature range (-55°C ~ 105°C)
• Identical material flammability rating (UL94 V-0) and MSL classification (1)

The substitute part maintains full electrical and mechanical compatibility with the original specification while offering improved availability and current product status.

Parameter Comparison

Engineering Selection Recommendations

The DF3E-3P-2V(54) is the appropriate substitute for the obsolete DF3E-3P-2V(50). Both parts maintain identical electrical and mechanical specifications across all critical parameters including pitch, voltage rating, operating temperature range, and flammability certification. The substitute part offers the advantage of Last Time Buy status with significantly higher inventory availability (2298 units versus 696 units), ensuring procurement continuity.

The DF3E-3P-2V(54) carries RoHS Compliance certification, providing additional environmental compliance benefits. The only non-functional differences are insulation color (Black versus Beige) and packaging format (Tube), neither of which affects electrical or mechanical performance in board-to-board or cable applications.

Frequently Asked Questions (FAQ)

Q: Are DF3E-3P-2V(50) and DF3E-3P-2V(54) electrically interchangeable?

A: Yes. Both parts share identical electrical specifications including 250VAC voltage rating, operating temperature range of -55°C to 105°C, contact material (Brass with Gold finish), and current rating characteristics based on wire gauge.

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

A: The primary differences are product status (Obsolete versus Last Time Buy), insulation color (Beige versus Black), packaging format (unspecified versus Tube), and RoHS compliance documentation. All electrical and mechanical parameters are identical.

Q: Can I use DF3E-3P-2V(54) in existing designs specified for DF3E-3P-2V(50)?

A: Yes. The substitute part maintains full compatibility with the original specification. The 2.00mm pitch, 3-position configuration, surface mount termination, and push-pull fastening are identical, ensuring direct board-level compatibility.

Q: Does the insulation color difference affect performance?

A: No. Insulation color is a cosmetic specification that does not affect electrical performance, mechanical fit, or thermal characteristics. Both Beige and Black insulation materials are Polyamide (PA) Nylon with identical UL94 V-0 flammability ratings.

Q: What is the significance of RoHS Compliance on the DF3E-3P-2V(54)?

A: RoHS Compliance indicates the part meets Restriction of Hazardous Substances directives, restricting lead and other hazardous materials. This provides environmental and regulatory compliance benefits for applications subject to RoHS requirements.

Q: Is the packaging difference significant for my application?

A: Packaging format (Tube for the substitute) affects handling, storage, and automated assembly processes but does not impact the connector's electrical or mechanical function. Verify compatibility with your procurement and assembly workflows.
