Substitute Part Grouping Explanation
The MA35-8P-2DS(51) qualifies as a direct substitute for the MA35-8P-2DS(71) based on the following critical parameters:
- Identical connector type, contact configuration, and pitch specifications (8 positions, 2 rows, 0.079" mating pitch)
- Matching electrical ratings (2A current, 200VAC voltage)
- Identical mechanical specifications (through-hole, right-angle mounting, kinked pin solder termination)
- Same operating temperature range (-55°C ~ 85°C)
- Identical contact materials, finishes, and insulation properties
- Same series designation (MA35) and base product number
The primary distinction is product status: MA35-8P-2DS(71) is obsolete, while MA35-8P-2DS(51) is active with RoHS compliance certification.
