Engineering Selection Recommendations

Primary Recommendation: 3M D2524-6002-AR

The D2524-6002-AR is the manufacturer-recommended direct substitute from 3M. It maintains identical electrical and mechanical specifications to the 2524-6002UG while offering active product status and RoHS compliance. The D2500 series design provides equivalent performance with improved regulatory standing. This part is suitable for new designs and production continuity.

Secondary Recommendation: 3M N2524-6002-RB

The N2524-6002-RB remains within the 3M 2500 series family with ROHS3 compliance and active status. It provides functional equivalence with the original part and maintains the same insulation height and contact geometry. This option is appropriate for applications requiring 3M ecosystem consistency.

Alternative Recommendation: Sullins SBH11-NBPC-D12-ST-BK

The Sullins SBH11-NBPC-D12-ST-BK offers ROHS3 compliance and active product status with enhanced current rating (3A versus 1.75A). The SBH11 series provides equivalent mechanical and electrical interchangeability. This option is suitable for applications with higher current requirements or where multi-source qualification is required.

Cross-Manufacturer Options: Molex 0878342441 and TE Connectivity 1-5103308-3

Both the Molex C-Grid 87834 series (0878342441) and TE Connectivity AMP-Latch series (1-5103308-3) provide functional equivalence with ROHS3 compliance and active status. These options support multi-source supply chain strategies. The TE Connectivity part offers extended operating temperature range (-65°C to 105°C) compared to the original specification.

Frequently Asked Questions (FAQ)

Q: Can the 2524-6002UG be directly replaced with any of these substitute parts?

A: Yes. All listed substitute parts maintain the critical parameters: 24-position, 2-row configuration at 0.100" (2.54mm) pitch, shrouded 4-wall design, through-hole mounting, solder termination, and push-pull fastening. Functional interchangeability is confirmed within the specified parameter envelope.

Q: What is the primary difference between the main part and its substitutes?

A: The 2524-6002UG is obsolete with RoHS non-compliance status. All substitute parts are active products with ROHS3 compliance, ensuring regulatory alignment for current production and new designs.

Q: Are there differences in contact material between substitutes?

A: Yes. The main part uses copper alloy contacts, while D2524-6002-AR uses brass, and SBH11-NBPC-D12-ST-BK uses brass. These material variations do not affect electrical performance within the specified current and voltage parameters.

Q: Does the post finish difference (tin-lead versus tin) affect compatibility?

A: No. Both tin-lead and tin post finishes are compatible with standard solder assembly processes. The change from tin-lead to tin reflects RoHS compliance requirements and does not impact functional performance.

Q: Which substitute offers the best thermal performance?

A: The TE Connectivity 1-5103308-3 specifies an extended operating temperature range of -65°C to 105°C, compared to the original -55°C to 105°C specification. This provides additional thermal margin for demanding applications.

Q: Are packaging differences significant for component selection?

A: Packaging format (tray, tube, or bulk) affects handling and assembly logistics but does not impact electrical or mechanical performance. Select based on production volume and assembly line requirements.

Q: Can I use the Sullins SBH11-NBPC-D12-ST-BK in place of the original part?

A: Yes. The SBH11 series provides full functional equivalence with identical pitch, position count, and mounting specifications. The higher current rating (3A) provides additional design margin without compromising compatibility.

Q: What compliance certifications should I verify for my application?

A: All substitute parts carry UL94 V-0 flammability certification and ROHS3 compliance. Verify REACH status requirements for your specific application region. The original part is REACH-affected; all substitutes are REACH-unaffected or vendor-undefined.
