Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF3-6S-2DSA(20) is determined by the following critical parameters:

• Connector Type & Position Count: Must be receptacle configuration with 6 positions
• Pitch Specification: Must maintain 0.079" (2.00mm) mating pitch
• Mounting & Termination: Must support through-hole solder termination
• Electrical Ratings: Must meet or exceed 3A current and 30VAC voltage requirements
• Mechanical Compatibility: Must maintain identical insulation height (0.232" / 5.90mm), contact length (0.118" / 3.00mm), and mating stacking heights (6.6mm, 7.5mm)
• Material & Contact Specifications: Must use phosphor bronze contacts with tin plating and polyamide insulation

The DF3-6S-2DSA(25) qualifies as a direct substitute, sharing all critical electrical, mechanical, and material specifications while offering improved product status and compliance certifications.

Parameter Comparison

Frequently Asked Questions (FAQ)

Q: Are DF3-6S-2DSA(20) and DF3-6S-2DSA(25) mechanically interchangeable?

A: Yes. Both connectors share identical pitch (0.079" / 2.00mm), insulation height (0.232" / 5.90mm), contact length (0.118" / 3.00mm), and mating stacking heights (6.6mm, 7.5mm). No PCB redesign or mechanical modification is required.

Q: What is the difference between DF3-6S-2DSA(20) and DF3-6S-2DSA(25)?

A: The primary differences are product status and compliance. DF3-6S-2DSA(20) is obsolete and RoHS non-compliant, while DF3-6S-2DSA(25) is an active product with ROHS3 compliance. Electrical and mechanical specifications are identical.

Q: Can DF3-6S-2DSA(25) be used in existing designs specified for DF3-6S-2DSA(20)?

A: Yes. The DF3-6S-2DSA(25) is a direct substitute with no design changes required. It maintains all electrical ratings (3A, 30VAC), operating temperature range (-30°C ~ 85°C), and mechanical dimensions.

Q: What packaging is available for the substitute part?

A: DF3-6S-2DSA(25) is supplied in tube packaging, suitable for both manual and automated assembly operations.

Q: Are there any compliance considerations when switching to DF3-6S-2DSA(25)?

A: The DF3-6S-2DSA(25) is ROHS3 compliant, which may be beneficial for systems requiring current regulatory compliance. Both parts are REACH unaffected and carry EAR99 ECCN classification.
