Substitute Part Grouping Explanation

The Preci-Dip 853-83-090-20-001101 qualifies as a direct substitute for the M50-3204545 based on the following critical parameters:

• Position Count & Pitch: Both connectors feature 90 positions with 0.050" (1.27mm) mating pitch and 2-row configuration with 0.050" row spacing
• Mounting & Termination: Both employ through-hole, right-angle mounting with solder termination
• Contact Configuration: Both provide female socket contacts with gold-plated mating surfaces
• Fastening Mechanism: Both utilize push-pull fastening
• Electrical Rating: Both are rated for 1A current
• Compliance: Both meet UL94 V-0 flammability and ROHS3 compliance requirements

The substitute part is currently active in production, addressing the obsolescence of the original component while maintaining mechanical and electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The Preci-Dip 853-83-090-20-001101 is the appropriate selection for applications currently using or requiring the M50-3204545. The substitute part maintains all critical mechanical and electrical parameters while offering the advantage of active production status and extended operating temperature range (-55°C to 125°C versus -40°C to 105°C). Both components satisfy UL94 V-0 flammability requirements and ROHS3 compliance, ensuring regulatory alignment. The substitute's increased gold plating thickness (29.5µin versus 10.0µin) provides enhanced contact durability. Existing PCB layouts and mating connector designs require no modification for this substitution.

Frequently Asked Questions (FAQ)
