Engineering Selection Recommendations

Both N2534-6002-RB and D2534-6002-AR are active production alternatives to the obsolete 2534-6002UG, with identical core electrical and mechanical specifications.

N2534-6002-RB is the direct functional equivalent within the 2500 series. It maintains all critical parameters including connector geometry, contact configuration, and operating characteristics. This part carries ROHS3 compliance and REACH unaffected status, addressing modern regulatory requirements. Bulk packaging is suitable for high-volume applications.

D2534-6002-AR represents the manufacturer-recommended alternative from the D2500 series. While maintaining identical mating pitch, row spacing, and electrical ratings, this variant features a reduced insulation height (0.253" versus 0.390") and brass contact material instead of copper alloy. This configuration is optimized for board-to-cable/wire applications. RoHS compliance and REACH unaffected status align with current environmental regulations. Tube packaging supports controlled component handling.

Selection between these substitutes depends on application requirements: N2534-6002-RB for board-to-board configurations matching the original design intent, or D2534-6002-AR for board-to-cable/wire applications with the manufacturer's recommended geometry.

Frequently Asked Questions (FAQ)

Q: Can N2534-6002-RB directly replace 2534-6002UG in existing designs?

A: Yes. N2534-6002-RB maintains identical mating pitch (0.100" / 2.54mm), row spacing, position count (34 positions, 2 rows), shrouding configuration, mounting method, and electrical ratings. The primary differences are product status (active versus obsolete), regulatory compliance (ROHS3 and REACH unaffected), and packaging format (bulk).

Q: What is the significance of the insulation height difference between N2534-6002-RB and D2534-6002-AR?

A: N2534-6002-RB maintains the original insulation height of 0.390" (9.91mm), suitable for board-to-board applications. D2534-6002-AR features a reduced insulation height of 0.253" (6.43mm), optimized for board-to-cable/wire configurations. This geometric difference affects mating stack height and connector profile in the application.

Q: Are there contact material differences between the substitutes?

A: Yes. The 2534-6002UG and N2534-6002-RB use copper alloy contacts, while D2534-6002-AR uses brass contacts. Both materials support the specified 1.75A current rating and -55°C to 105°C operating temperature range. Contact finish specifications (gold mating surface, tin or tin-lead post finish) remain consistent across all variants.

Q: What packaging options are available?

A: N2534-6002-RB is supplied in bulk packaging, suitable for high-volume procurement. D2534-6002-AR is supplied in tube packaging, providing organized component presentation and controlled handling. Packaging selection depends on assembly process requirements and inventory management practices.

Q: How do regulatory compliance statuses differ?

A: The original 2534-6002UG is RoHS non-compliant and REACH affected. Both substitutes (N2534-6002-RB and D2534-6002-AR) are RoHS compliant and REACH unaffected, meeting current environmental and regulatory standards for new designs and procurement.

Q: Are the contact finish specifications identical across all three parts?

A: Mating contact finish is gold across all variants. Post contact finish differs: the 2534-6002UG uses tin-lead, while N2534-6002-RB and D2534-6002-AR use tin. Contact finish thickness also varies: mating contact thickness ranges from 10.0µin to 30.0µin, and post contact thickness ranges from 39.4µin to 200.0µin across the three parts.
