Key Parameters

Substitute Part Grouping Explanation

The MA35-50P-2DS(51) qualifies as a direct substitute based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Identical series designation (MA35)
• Identical number of positions (50) and row configuration (2 rows)
• Identical pitch specifications (0.079" / 2.00mm mating pitch and row spacing)
• Identical contact type (Male Pin), mounting type (Through Hole, Right Angle), and termination method (Kinked Pin, Solder)
• Identical electrical ratings (2A current, 200VAC voltage)
• Identical operating temperature range (-55°C ~ 85°C)
• Identical material specifications (Brass contacts, Polyamide/Nylon insulation, Tin finish)
• Identical flammability rating (UL94 V-0)

The primary distinction is product status: MA35-50P-2DS(71) is obsolete, while MA35-50P-2DS(51) is active and RoHS Compliant.

Parameter Comparison

Engineering Selection Recommendations

The MA35-50P-2DS(51) is the direct functional equivalent of the MA35-50P-2DS(71). All electrical, mechanical, and material specifications are identical. The MA35-50P-2DS(51) is the preferred selection for new designs and ongoing production due to its active product status and RoHS Compliance certification. The obsolete status of MA35-50P-2DS(71) indicates end-of-life designation by the manufacturer, making MA35-50P-2DS(51) the appropriate long-term solution for component sourcing.

Frequently Asked Questions (FAQ)

Q: Can MA35-50P-2DS(51) be used as a direct replacement for MA35-50P-2DS(71)?

A: Yes. Both parts share identical electrical ratings (2A, 200VAC), mechanical dimensions (50 positions, 2 rows, 2.00mm pitch), contact specifications (Male Pin, Brass, Tin finish), and operating temperature range (-55°C ~ 85°C). Physical and functional compatibility is complete.

Q: What is the difference between these two part numbers?

A: The primary difference is product lifecycle status. MA35-50P-2DS(71) is obsolete, while MA35-50P-2DS(51) is active and carries RoHS Compliance certification. The connector specifications are otherwise identical.

Q: Are there packaging differences between these parts?

A: MA35-50P-2DS(71) packaging is not specified in available documentation. MA35-50P-2DS(51) is supplied in bulk packaging. Confirm packaging requirements with your procurement department.

Q: Is RoHS Compliance a requirement for my application?

A: RoHS Compliance is mandatory for products sold in the European Union and many other markets. MA35-50P-2DS(51) meets this requirement. If RoHS Compliance is required for your application, MA35-50P-2DS(51) is the appropriate selection.

Q: Can I use MA35-50P-2DS(51) in existing designs originally specified for MA35-50P-2DS(71)?

A: Yes. Identical electrical and mechanical parameters ensure full compatibility with existing PCB layouts, mating connectors, and circuit designs. No design modifications are required.
