DF3-2P-2DS Equivalent & Substitute Parts

Part Overview

The DF3-2P-2DS is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for through-hole, right-angle board-to-board or cable applications. This 2-position connector operates at 3A current rating with a 2.00mm pitch and features shrouded 4-wall construction with push-pull fastening. The DF3-2P-2DS carries an obsolete product status, making identification of compatible alternatives essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF3-2P-2DS is determined by strict equivalence across the following critical parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 2
• Pitch - Mating: 0.079" (2.00mm)
• Mounting Type: Through Hole, Right Angle
• Shrouding: Shrouded - 4 Wall
• Current Rating: 3A
• Operating Temperature: -55°C ~ 105°C
• Material Flammability Rating: UL94 V-0
• Fastening Type: Push-Pull
• Contact Shape: Square
• Contact Material: Brass
• Insulation Material: Polyamide (PA), Nylon

The DF3A-2P-2DS meets all these criteria and is classified as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The DF3A-2P-2DS is the direct substitute for the DF3-2P-2DS. Both parts are manufactured by Hirose Electric Co Ltd and share identical electrical and mechanical specifications across all critical parameters.

The primary distinction is product lifecycle status: the DF3-2P-2DS is obsolete, while the DF3A-2P-2DS maintains active product status. Additionally, the DF3A-2P-2DS is ROHS3 compliant, whereas the DF3-2P-2DS is RoHS non-compliant. The DF3A-2P-2DS also demonstrates superior inventory availability with 2600 units in stock compared to 1195 units of the obsolete variant.

For new designs or ongoing procurement, the DF3A-2P-2DS is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can the DF3A-2P-2DS directly replace the DF3-2P-2DS in existing applications?

A: Yes. Both connectors are electrically and mechanically equivalent across all specified parameters, including pitch, position count, current rating, operating temperature range, and shrouding configuration.

Q: What is the difference between the DF3-2P-2DS and DF3A-2P-2DS?

A: The DF3A-2P-2DS is the active production variant with ROHS3 compliance. The DF3-2P-2DS is obsolete and RoHS non-compliant. All functional and dimensional specifications are identical.

Q: Why is the DF3-2P-2DS listed as obsolete?

A: Product obsolescence is determined by the manufacturer. The DF3A-2P-2DS serves as the current production replacement within the DF3 series.

Q: Are there any compatibility concerns when switching from DF3-2P-2DS to DF3A-2P-2DS?

A: No compatibility concerns exist. The connectors are pin-compatible and dimensionally equivalent. PCB footprints and mating connector designs require no modification.

Q: What is the significance of ROHS3 compliance on the DF3A-2P-2DS?

A: ROHS3 compliance indicates the DF3A-2P-2DS meets current regulatory requirements for restricted hazardous substances. This is relevant for applications subject to environmental and regulatory compliance mandates.
