3M 2564-6002UB Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The 3M 2564-6002UB is a through-hole rectangular connector header with 64 positions arranged in 2 rows at 0.100" (2.54mm) pitch. This shrouded 4-wall header features male pins with gold-plated mating contacts and tin-lead post finish, designed for board-to-board or cable applications. The part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts must maintain electrical and mechanical compatibility while meeting current compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2564-6002UB is determined by the following critical parameters: 64-position count, 2-row configuration, 0.100" (2.54mm) mating pitch, 0.100" (2.54mm) row spacing, shrouded 4-wall design, through-hole mounting, solder termination, male pin contact type, and board-to-board or cable style. All substitute parts must maintain these core electrical and mechanical specifications to ensure direct compatibility with existing PCB layouts and mating connectors.

The two identified substitutes are grouped as follows:

Direct 3M Series Substitute: N2564-6002-RB maintains identical specifications within the 3M 2500 series family, with the primary distinction being active product status and improved compliance profile.

Cross-Manufacturer Substitute: SBH11-PBPC-D32-ST-BK from Sullins Connector Solutions provides functional equivalence with variations in contact material, insulation material, and performance ratings that remain within acceptable substitution parameters.

Parameter Comparison

Engineering Selection Recommendations

N2564-6002-RB (3M): This substitute is the preferred direct replacement for the obsolete 2564-6002UB. It maintains identical electrical and mechanical specifications within the 3M 2500 series while offering active product status and improved compliance. The part is ROHS3 compliant and REACH unaffected, addressing regulatory requirements of the original obsolete part. The only material difference is the post finish change from tin-lead to tin, which does not affect functional compatibility. This part is recommended for applications requiring minimal design validation.

SBH11-PBPC-D32-ST-BK (Sullins Connector Solutions): This cross-manufacturer substitute provides functional equivalence with notable differences in contact material (brass vs. copper alloy), insulation material (PBT vs. PCT/polyester), and performance ratings (3A current vs. 1.75A, -40°C to 105°C vs. -55°C to 105°C). The Sullins part is ROHS3 compliant and REACH unaffected. Selection of this substitute requires verification that the application does not require the full -55°C lower temperature limit and that the higher current rating does not introduce thermal or reliability concerns in the specific circuit design. This part is suitable for applications where cross-manufacturer sourcing is acceptable and design validation has been completed.

Frequently Asked Questions (FAQ)

Q: Can N2564-6002-RB be used as a direct drop-in replacement for 2564-6002UB?

A: Yes. The N2564-6002-RB maintains identical pin count (64), row configuration (2), pitch (0.100"), shrouding (4-wall), mounting type (through-hole), and termination method (solder). The post finish change from tin-lead to tin does not affect electrical or mechanical compatibility. PCB layouts and mating connectors designed for 2564-6002UB will accept N2564-6002-RB without modification.

Q: What are the key differences between N2564-6002-RB and SBH11-PBPC-D32-ST-BK?

A: Both parts share the same 64-position, 2-row, 0.100" pitch configuration. Differences include: contact material (copper alloy vs. brass), insulation material (PCT/polyester vs. PBT), current rating (1.75A vs. 3A), operating temperature range (-55°C to 105°C vs. -40°C to 105°C), and post finish (tin vs. gold). These differences may affect performance in extreme temperature or high-current applications.

Q: Is the SBH11-PBPC-D32-ST-BK suitable for applications requiring -55°C operation?

A: No. The SBH11-PBPC-D32-ST-BK has a minimum operating temperature of -40°C, which does not meet the -55°C specification of the original 2564-6002UB. Applications requiring -55°C operation must use N2564-6002-RB or the original part.

Q: What compliance improvements do the substitute parts offer?

A: Both N2564-6002-RB and SBH11-PBPC-D32-ST-BK are ROHS3 compliant and REACH unaffected, addressing the regulatory limitations of the obsolete 2564-6002UB, which is RoHS non-compliant and REACH affected.

Q: Are there packaging differences between these parts?

A: Yes. The 2564-6002UB is supplied in unspecified packaging, N2564-6002-RB is supplied in bulk packaging, and SBH11-PBPC-D32-ST-BK is supplied in tray packaging. Packaging selection may affect handling, storage, and procurement logistics but does not affect component functionality.

Q: Can these parts be intermixed in the same assembly?

A: Yes, provided the application does not require the full -55°C operating temperature range. Both substitute parts are mechanically and electrically compatible with the same mating connectors and PCB footprints. However, mixing parts with different current ratings (1.75A vs. 3A) in the same circuit should be evaluated for thermal and reliability implications.
