3M 2560-6002UB Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The 3M 2560-6002UB is a through-hole rectangular connector header with 60 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 finishes, designed for board-to-board or cable applications. The part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Active alternatives from multiple manufacturers provide functional equivalence while offering improved compliance status and availability.

Substitute Part Grouping Explanation

Substitution eligibility for the 2560-6002UB is determined by strict equivalence across the following critical parameters:

Connector Type & Contact Configuration: Header with male pins, 60 positions in 2 rows
Pitch Specification: 0.100" (2.54mm) mating pitch and 0.100" row spacing
Shrouding & Mounting: Shrouded 4-wall design with through-hole solder termination
Fastening Mechanism: Push-pull fastening type
Contact Geometry: Square contact shape with gold mating finish
Environmental Rating: UL94 V-0 flammability compliance and MSL 1 rating

All identified substitutes meet these core electrical and mechanical parameters. Variations in contact material, insulation material, post finish specifications, and compliance status are secondary considerations that do not affect functional interchangeability in standard applications.

Engineering Selection Recommendations

Primary Recommendation: N2560-6002-RB (3M)

The N2560-6002-RB is the direct active equivalent from the original manufacturer. It maintains identical electrical and mechanical specifications to the 2560-6002UB while offering ROHS3 compliance and active product status. The only material difference is the post finish specification (tin versus tin-lead), which does not affect functional interchangeability. This part provides the lowest risk substitution path for existing designs.

Secondary Recommendations for Multi-Source Strategy:

HIF3FB-60PA-2.54DSA(71) (Hirose) and SBH11-PBPC-D30-ST-BK (Sullins) are both ROHS3-compliant active parts meeting all core parameters. Both offer higher current ratings (1A and 3A respectively) compared to the original 1.75A specification, providing design margin for power delivery applications.

1-5103308-2 (TE Connectivity) is an active ROHS3-compliant alternative with extended operating temperature range (-65°C to 105°C) suitable for military or aerospace applications requiring broader thermal performance.

0878346011 (Molex) provides ROHS3 compliance and active status with board guide features, though insulation material differs (polyamide versus PCT/polyester).

Parts to Avoid for New Designs:

66506-057 and 78280-460 (both Amphenol ICC) retain RoHS non-compliance status matching the original part. These are suitable only for legacy system maintenance where RoHS compliance is not required.

Frequently Asked Questions (FAQ)

Q: Can I directly replace 2560-6002UB with N2560-6002-RB without PCB modifications?

A: Yes. The N2560-6002-RB maintains identical footprint, pitch, shrouding, and mounting specifications. No PCB layout changes are required. The tin post finish on N2560-6002-RB is compatible with standard solder reflow processes.

Q: What is the difference between the original 2560-6002UB and its substitutes in terms of contact material?

A: The original uses copper alloy contacts. Substitutes vary: N2560-6002-RB uses copper alloy; Molex 0878346011 uses copper alloy; TE 1-5103308-2 uses brass; Amphenol parts use phosphor bronze; Hirose and Sullins use brass. All materials are compatible with standard PCB assembly and provide equivalent electrical performance for this connector class.

Q: Are all substitute parts RoHS compliant?

A: No. N2560-6002-RB, 0878346011, 1-5103308-2, HIF3FB-60PA-2.54DSA(71), and SBH11-PBPC-D30-ST-BK are ROHS3 compliant. The Amphenol parts (66506-057 and 78280-460) are RoHS non-compliant. For new designs targeting EU or regulated markets, select only ROHS3-compliant alternatives.

Q: What packaging options are available for these substitutes?

A: N2560-6002-RB ships in bulk packaging. Molex 0878346011 has unspecified packaging. TE 1-5103308-2 comes in tube. Amphenol 66506-057 is in tray; 78280-460 is in bulk. Hirose HIF3FB-60PA-2.54DSA(71) and Sullins SBH11-PBPC-D30-ST-BK are both in tray. Verify packaging requirements with your procurement process.

Q: Do these connectors support the same current rating?

A: The original 2560-6002UB is rated at 1.75A per contact. N2560-6002-RB maintains this rating. TE 1-5103308-2 is rated at 1A per contact. Hirose HIF3FB-60PA-2.54DSA(71) is rated at 1A. Sullins SBH11-PBPC-D30-ST-BK is rated at 3A. Amphenol and Molex parts do not specify current ratings. For applications requiring 1.75A or higher, confirm the selected substitute meets your current requirements.

Q: What is the operating temperature range for each substitute?

A: The original 2560-6002UB operates from -55°C to 105°C. N2560-6002-RB maintains this range. TE 1-5103308-2 extends to -65°C to 105°C. Hirose HIF3FB-60PA-2.54DSA(71) operates -55°C to 85°C, which is narrower. Sullins SBH11-PBPC-D30-ST-BK operates -40°C to 105°C. Amphenol and Molex parts do not specify operating temperature. Verify thermal requirements before selection.

Q: Are all these parts available in the same quantity?

A: Inventory levels vary. Current stock includes: 2560-6002UB (1022 pcs), N2560-6002-RB (2239 pcs), Molex 0878346011 (627 pcs), TE 1-5103308-2 (951 pcs), Amphenol 66506-057 (783 pcs), Amphenol 78280-460 (874 pcs), Hirose HIF3FB-60PA-2.54DSA(71) (931 pcs), and Sullins SBH11-PBPC-D30-ST-BK (642 pcs).
