Substitute Part Grouping Explanation

Substitution eligibility for the MA35-12P-2DS(71) is determined by strict equivalence across the following critical parameters:

• Connector Series & Type: Must be MA35 series header connector
• Position Configuration: 12 positions in 2-row arrangement
• Pitch Specification: 0.079" (2.00mm) mating pitch and row spacing
• Mounting & Orientation: Through-hole, right-angle mounting
• Contact Characteristics: Male pin contacts with kinked pin solder termination
• Electrical Ratings: 2A current rating and 200VAC voltage rating
• Operating Temperature Range: -55°C to 85°C
• Material & Compliance: Brass contacts with tin finish, polyamide insulation, UL94 V-0 flammability rating

The MA35-12P-2DS(51) meets all these criteria and is classified as an active product, providing direct functional equivalence with improved availability and current manufacturing status.

Parameter Comparison
