Engineering Selection Recommendations

The 5-146277-5 is the manufacturer-recommended substitute for the obsolete 102976-5. Both connectors share identical electrical and mechanical specifications across all critical parameters, including pitch, contact configuration, current rating, and operating temperature range.

The primary distinction is product status: the 102976-5 is obsolete with limited inventory availability, while the 5-146277-5 is active production with robust stock levels (6196 pcs available). Additionally, the 5-146277-5 achieves ROHS3 compliance, whereas the 102976-5 is RoHS non-compliant. The insulation material differs (Liquid Crystal Polymer vs. Thermoplastic), and the post finish is tin rather than tin-lead; these material changes do not affect functional compatibility for the specified application parameters.

For new designs or component replenishment, the 5-146277-5 is the appropriate selection. For legacy system maintenance requiring exact material matching, the 102976-5 remains available in current inventory.

Frequently Asked Questions (FAQ)

Q: Are the 102976-5 and 5-146277-5 electrically interchangeable?

A: Yes. Both connectors meet identical electrical specifications: 3A current rating, -65°C to 105°C operating temperature, 0.100" (2.54mm) pitch, and gold-plated mating contacts. They are functionally equivalent for electrical performance.

Q: What is the difference in insulation material, and does it affect compatibility?

A: The 102976-5 uses thermoplastic insulation, while the 5-146277-5 uses Liquid Crystal Polymer (LCP). Both materials achieve UL94 V-0 flammability rating and support the same operating temperature range. The material change does not affect mechanical or electrical compatibility.

Q: Why is the post finish different (tin-lead vs. tin)?

A: The 102976-5 features tin-lead plating on the solder posts, while the 5-146277-5 uses tin plating. Both finishes provide equivalent solderability and contact resistance for the specified 3A current rating. The tin finish in the 5-146277-5 reflects modern RoHS3 compliance requirements.

Q: Can I use the 5-146277-5 in place of the 102976-5 in existing designs?

A: Yes. The 5-146277-5 is the manufacturer-recommended substitute and maintains identical mechanical dimensions, pitch spacing, contact geometry, and electrical performance. No design modifications are required.

Q: What is the availability difference between these parts?

A: The 102976-5 is obsolete with 935 pcs in current inventory. The 5-146277-5 is active production with 6196 pcs available, ensuring long-term supply continuity.

Q: Does the RoHS compliance difference matter for my application?

A: The 5-146277-5 is ROHS3 compliant, while the 102976-5 is RoHS non-compliant. If your application or regulatory requirements mandate RoHS compliance, the 5-146277-5 is the required selection. For legacy systems without RoHS requirements, both parts are functionally suitable.
