Substitute Part Grouping Explanation

The DF3-8S-2DSA(50) can be substituted with DF3-8S-2DSA(55) based on the following critical parameters that determine functional equivalence:

• Connector Type & Contact Configuration: Both are 8-position receptacles with female socket contacts
• Pitch Specification: Identical 0.079" (2.00mm) mating pitch ensures mechanical compatibility
• Electrical Ratings: Both support 3A current and 30VAC voltage specifications
• Mounting & Termination: Both use through-hole solder termination with friction lock fastening
• Operating Temperature Range: Identical -30°C ~ 85°C operating range
• Contact Material & Finish: Both use phosphor bronze contacts with gold mating finish and tin post finish
• Insulation Properties: Both feature polyamide (PA) nylon insulation with UL94 V-0 flammability rating

The primary distinction is product status: DF3-8S-2DSA(50) is obsolete, while DF3-8S-2DSA(55) is active with improved compliance documentation.

Parameter Comparison

Engineering Selection Recommendations

The DF3-8S-2DSA(55) is the direct substitute for DF3-8S-2DSA(50). Selection between these parts should be based on the following criteria:

Use DF3-8S-2DSA(55) when:

• New designs require ROHS3 compliance
• Active product support and ongoing availability are required
• Regulatory documentation and compliance certifications are necessary

Use DF3-8S-2DSA(50) when:

• Existing inventory must be consumed for legacy system maintenance
• RoHS compliance is not a design requirement
• Cost optimization for non-regulated applications is the priority

Both parts are electrically and mechanically equivalent for all functional parameters specified in this reference.

Frequently Asked Questions (FAQ)
