Key Parameters

Substitute Part Grouping Explanation

Substitution for the DF3-3S-2DSA(20) is determined by strict equivalence across the following critical parameters:

• Connector type: Receptacle
• Number of positions: 3
• Pitch specification: 0.079" (2.00mm)
• Mounting method: Through hole
• Termination type: Solder
• Current rating: 3A minimum
• Voltage rating: 30VAC minimum
• Operating temperature range: -30°C to 85°C minimum
• Series compatibility: DF3

The DF3-3S-2DSA(25) meets all substitution criteria within the DF3 series, with identical electrical and mechanical specifications. The primary distinction is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The DF3-3S-2DSA(25) is the direct substitute for the obsolete DF3-3S-2DSA(20). Both parts are electrically and mechanically identical across all functional parameters. The DF3-3S-2DSA(25) carries active product status and ROHS3 compliance certification, whereas the DF3-3S-2DSA(20) is obsolete and RoHS non-compliant. For new designs or ongoing production requiring regulatory compliance, the DF3-3S-2DSA(25) is the appropriate selection. Inventory availability is higher for the substitute part (1063 pcs vs. 736 pcs).

Frequently Asked Questions (FAQ)

Q: Are DF3-3S-2DSA(20) and DF3-3S-2DSA(25) mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including pitch, mounting type, insulation height, contact length, and stacking heights. Direct substitution is possible without PCB redesign.

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

A: The primary differences are product status (obsolete vs. active), RoHS compliance certification (non-compliant vs. ROHS3 compliant), and packaging format. Electrical and mechanical performance are equivalent.

Q: Can DF3-3S-2DSA(25) be used in existing designs originally specified for DF3-3S-2DSA(20)?

A: Yes. The substitute part meets all electrical and mechanical requirements of the original specification. No circuit modifications are required.

Q: What is the significance of the packaging difference?

A: DF3-3S-2DSA(20) has unspecified packaging, while DF3-3S-2DSA(25) is supplied in tube packaging. This affects handling and storage procedures but does not impact connector performance or compatibility.

Q: Why is RoHS compliance important for this substitution?

A: ROHS3 compliance ensures the connector meets current environmental and regulatory standards for lead-free manufacturing. This is critical for products destined for markets with RoHS requirements.
