Engineering Selection Recommendations

Primary Recommendation: TE Connectivity 5-146257-7

The 5-146257-7 is the direct active equivalent from the original manufacturer TE Connectivity. This part maintains identical electrical and mechanical specifications to the obsolete 4-146257-6, including contact length dimensions, pitch spacing, and row configuration. The primary difference is the contact finish on the post, which changes from Tin-Lead to Tin. This change aligns with RoHS3 compliance requirements and represents standard industry practice for lead-free manufacturing. The 5-146257-7 is classified as Active with 5155 units in stock, ensuring supply continuity.

Secondary Recommendations: Molex C-Grid 70280 Series

The Molex C-Grid 70280 series (part numbers 0010897140, 0010897141, 0010897142, 0702800595, 0702800635, 0702800675) provides functionally equivalent alternatives. These parts maintain identical mating pitch, position count, row spacing, and fastening characteristics. Variations exist in contact length dimensions and contact finish specifications. The 0010897140 and 0010897142 variants with gold mating finish provide closest alignment to the original specification. All C-Grid 70280 parts are ROHS3 Compliant with MSL 1 rating and are classified as Active.

Tertiary Recommendations: Molex C-Grid 70287 Series

The Molex C-Grid 70287 series (part numbers 0702871005, 0702871103, 0702871201) offers substitution with kinked pin termination in addition to solder termination. These parts maintain identical mating pitch and position configuration but feature different contact post lengths (0.125" versus 0.120" in the original). The 0702871103 and 0702871201 variants with gold mating finish provide closest alignment to the original specification. All C-Grid 70287 parts are ROHS3 Compliant with MSL 1 rating and are classified as Active.

Compliance Considerations

All recommended substitutes are ROHS3 Compliant, meeting current regulatory requirements. The transition from Tin-Lead to Tin post finish in the 5-146257-7 reflects mandatory lead-free manufacturing standards. All substitute parts maintain UL94 V-0 flammability rating and Moisture Sensitivity Level 1 classification, ensuring compatibility with existing design requirements.

Frequently Asked Questions (FAQ)

Q: Can the 5-146257-7 directly replace the obsolete 4-146257-6 without PCB modifications?

A: Yes. The 5-146257-7 maintains identical mating pitch (0.100"), position count (14), row spacing (0.100"), and mounting type (through hole). Contact length dimensions are identical. The only material change is the post finish from Tin-Lead to Tin, which does not affect mechanical fit or electrical performance in standard solder joint applications.

Q: What is the difference between the TE Connectivity 5-146257-7 and the Molex C-Grid 70280 alternatives?

A: The 5-146257-7 is the direct manufacturer upgrade from TE Connectivity with identical contact length specifications. Molex C-Grid 70280 parts feature slightly longer mating contact length (0.240" versus 0.230") and shorter post length (0.107" versus 0.120"). These dimensional differences do not affect mating compatibility but may impact board layout considerations for post-side clearance.

Q: Are the Molex C-Grid 70287 parts with kinked pin termination compatible with standard PCB designs?

A: The C-Grid 70287 series maintains identical mating pitch and position configuration, ensuring mating compatibility. The kinked pin termination provides additional mechanical retention during soldering. Post length is 0.125", which differs from the original 0.120". This 0.005" difference is within typical PCB tolerance ranges but should be verified for applications with tight clearance requirements.

Q: What contact finish options are available among the substitutes?

A: The primary substitute (5-146257-7) and most Molex alternatives offer gold mating finish with tin post finish. Specific variants include: gold mating finish (0010897140, 0010897142, 0702800635, 0702800675, 0702871103, 0702871201) and tin mating finish (0010897141, 0702800595, 0702871005). Gold mating finish provides superior corrosion resistance and is recommended for applications requiring extended shelf life or harsh environmental exposure.

Q: Are all substitute parts RoHS compliant?

A: Yes. All recommended substitutes are ROHS3 Compliant. The original 4-146257-6 is RoHS Compliant. The transition to ROHS3 Compliant parts reflects current regulatory standards and eliminates lead from post finishes, aligning with mandatory lead-free manufacturing requirements.

Q: What is the Moisture Sensitivity Level (MSL) for all substitute parts?

A: All substitute parts, including the original 4-146257-6, are classified as MSL 1 (Unlimited). This classification indicates no moisture sensitivity restrictions and no special storage or handling requirements prior to soldering.

Q: Can I mix different substitute part numbers in the same assembly?

A: All recommended substitutes maintain identical mating pitch, position count, and row spacing, allowing mechanical interchangeability. However, mixing parts with different contact finish specifications or post lengths within the same assembly is not recommended. Maintain consistency within a single design to ensure uniform electrical and mechanical performance.

Q: What is the current rating for the Molex substitute parts?

A: The Molex C-Grid 70280 and C-Grid 70287 series do not specify current rating in the provided documentation. The original TE Connectivity 4-146257-6 and 5-146257-7 are rated at 3A per contact. For applications requiring current rating verification, contact the manufacturer directly or consult detailed product datasheets.

Q: Are there any operating temperature differences between the original and substitute parts?

A: The original TE Connectivity 4-146257-6 and 5-146257-7 specify operating temperature range of -65°C to 105°C. The Molex C-Grid 70280 and C-Grid 70287 series do not specify operating temperature in the provided documentation. For temperature-critical applications, verify Molex specifications with the manufacturer or use the TE Connectivity 5-146257-7 to maintain documented temperature performance.
