Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF3-5S-2DSA(20) is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: Receptacle, 5-position, board-to-board or cable style
• Electrical Specifications: 3A current rating, 30VAC voltage rating
• Mechanical Interface: 0.079" (2.00mm) pitch, through-hole mounting, solder termination
• Environmental & Material Compliance: UL94 V-0 flammability rating, operating temperature range -30°C to 85°C
• Contact Properties: Tin-plated female socket contacts, phosphor bronze material

The DF3-5S-2DSA(25) qualifies as a direct substitute, maintaining identical electrical, mechanical, and environmental specifications while differing only in packaging format and product lifecycle status.

Parameter Comparison

Engineering Selection Recommendations

The DF3-5S-2DSA(25) is the direct functional equivalent for the obsolete DF3-5S-2DSA(20). Both parts maintain identical electrical performance (3A, 30VAC), mechanical interface (0.079" pitch, through-hole solder termination), and environmental specifications (UL94 V-0, -30°C to 85°C operating range).

Key differentiation factors:

• Product Lifecycle: DF3-5S-2DSA(20) is obsolete; DF3-5S-2DSA(25) is Last Time Buy status, providing extended procurement window
• Regulatory Compliance: DF3-5S-2DSA(25) achieves ROHS3 compliance, whereas DF3-5S-2DSA(20) is non-compliant
• Packaging: DF3-5S-2DSA(25) is supplied in tube packaging

For new designs or ongoing production requiring RoHS compliance, DF3-5S-2DSA(25) is the appropriate selection. For legacy systems where RoHS compliance is not mandated, both parts are electrically and mechanically interchangeable.

Frequently Asked Questions (FAQ)

Q: Are DF3-5S-2DSA(20) and DF3-5S-2DSA(25) pin-compatible?

A: Yes. Both connectors feature identical 5-position, 0.079" (2.00mm) pitch receptacle configurations with matching contact geometry, insulation height, and mating stacking heights (6.6mm, 7.5mm). They are directly interchangeable at the board level.

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

A: The primary differences are product status, RoHS compliance, and packaging. DF3-5S-2DSA(20) is obsolete and RoHS non-compliant, while DF3-5S-2DSA(25) is Last Time Buy status and ROHS3 compliant. Both maintain identical electrical and mechanical specifications.

Q: Can DF3-5S-2DSA(25) be used as a direct replacement in existing assemblies?

A: Yes. The DF3-5S-2DSA(25) is a direct substitute with no design modifications required. Electrical performance (3A, 30VAC), operating temperature range (-30°C to 85°C), and physical dimensions are identical.

Q: Does the packaging difference affect compatibility?

A: No. Packaging format (tube for DF3-5S-2DSA(25)) affects only handling and storage logistics, not electrical or mechanical performance. The connector itself is identical.

Q: Which part should be selected for new designs?

A: DF3-5S-2DSA(25) is recommended for new designs due to Last Time Buy availability and ROHS3 compliance. DF3-5S-2DSA(20) should not be selected for new applications given its obsolete status.
