Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MA35-32P-2DS(71) is determined by the following critical parameters:

• Manufacturer series compatibility (MA35 series)
• Connector type and contact configuration (Header, Male Pin)
• Pitch specification (2.00mm mating pitch)
• Mounting method (Through Hole, Right Angle)
• Electrical ratings (minimum 2A current, 200VAC voltage)
• Operating temperature range (-55°C ~ 85°C)
• Material flammability compliance (UL94 V-0)

The MA35-32P-2DS(51) qualifies as a direct substitute based on these parameters. While the position count differs (32 vs. 30), both connectors share identical electrical, mechanical, and thermal specifications within the MA35 series architecture.

Parameter Comparison

Engineering Selection Recommendations

The MA35-32P-2DS(51) is the qualified substitute for the obsolete MA35-32P-2DS(71). Both components maintain identical electrical performance specifications, mechanical dimensions, and thermal operating ranges. The substitute part carries Active product status and RoHS Compliance certification, providing assurance of continued manufacturing availability and regulatory alignment.

The primary design consideration is the position count differential: the substitute provides 32 positions versus the original 30 positions. This increased capacity does not compromise compatibility with existing mating interfaces within the MA35 series architecture, as the pitch, row spacing, and contact geometry remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can MA35-32P-2DS(51) directly replace MA35-32P-2DS(71) in existing designs?

A: Yes. Both connectors share identical pitch (2.00mm), row spacing, mounting configuration, and electrical ratings. The 32-position variant accommodates the same mating interface geometry as the 30-position original.

Q: What is the significance of the position count difference?

A: The MA35-32P-2DS(51) provides two additional contact positions. In applications utilizing only 30 positions, the extra positions remain unused without affecting circuit performance. In new designs, the additional positions offer expanded connectivity capacity within the same physical footprint.

Q: Are there compliance differences between these parts?

A: The MA35-32P-2DS(71) carries UL94 V-0 flammability rating. The MA35-32P-2DS(51) maintains identical UL94 V-0 compliance and adds RoHS Compliance certification, reflecting current regulatory standards.

Q: What packaging format is available for the substitute?

A: The MA35-32P-2DS(51) is supplied in Bulk packaging, with 692 pieces currently in stock as new original inventory.

Q: Are electrical and thermal specifications identical?

A: Yes. Both parts operate at 2A current rating, 200VAC voltage rating, and -55°C to 85°C temperature range. Contact finish, material composition, and insulation specifications are identical.
