Engineering Selection Recommendations

Primary Substitutes (Molex C-Grid 70280 and 70287 Series):

The Molex C-Grid 70280 and 70287 series connectors (part numbers 0010897140, 0010897141, 0010897142, 0702800595, 0702800635, 0702800675, 0702871005, 0702871103, 0702871201) are active products with ROHS3 compliance and REACH unaffected status. These parts maintain full mechanical and electrical compatibility with the 146255-7 across all critical parameters: 14-position, 2-row, 2.54mm pitch configuration, unshrouded breakaway headers with square contacts, LCP insulation material, UL94 V-0 flammability rating, and solder termination with push-pull fastening.

Selection within the Molex C-Grid series depends on contact post length requirements:

Standard post length (0.107" to 0.125"): Parts 0010897140, 0010897141, 0010897142, 0702871005, 0702871103, 0702871201
Extended post length (0.175"): Parts 0702800595, 0702800635, 0702800675

Contact finish selection (Gold or Tin) and contact finish thickness variations are available across all Molex options to accommodate specific application requirements.

Alternative Substitute (Preci-Dip 450 Series):

The Preci-Dip 450-V3-214-00-006101 is an active product with ROHS3 compliance and REACH unaffected status. This part maintains the 14-position, 2-row, 2.54mm pitch configuration and solder termination. Differences include circular contact shape (versus square), PCT/Polyester/Glass Filled insulation material (versus LCP), higher voltage rating (150VDC versus 30VAC), and extended operating temperature range (-55°C to 125°C versus -65°C to 105°C). The Preci-Dip option is suitable for applications requiring enhanced voltage performance and wider temperature operation.

Compliance Considerations:

All substitute parts listed are active products with current manufacturing status. The Molex C-Grid series provides ROHS3 compliance and REACH unaffected certification. The Preci-Dip 450 series also provides ROHS3 compliance and REACH unaffected certification. Selection of any substitute part eliminates the RoHS non-compliance status of the obsolete 146255-7.

Frequently Asked Questions (FAQ)

Q: Can Molex C-Grid 70280 and 70287 series connectors directly replace the TE Connectivity 146255-7?

A: Yes. The Molex C-Grid 70280 and 70287 series maintain full compatibility with the 146255-7 across all critical parameters: 14-position, 2-row, 2.54mm pitch, unshrouded breakaway headers, male pin contacts, square contact shape, LCP insulation, UL94 V-0 rating, solder termination, and push-pull fastening. These parts are mechanically and electrically interchangeable with the obsolete TE Connectivity component.

Q: What is the difference between Molex C-Grid 70280 and 70287 series?

A: The primary difference is contact post length. The C-Grid 70280 series offers standard post lengths of 0.107" to 0.175", while the C-Grid 70287 series provides a post length of 0.125". Selection depends on the specific through-hole depth and solder pad configuration of the target circuit board. Both series maintain identical mating contact length (0.240"), pitch, and position count.

Q: How do contact finish options affect substitution?

A: Contact finish (Gold or Tin) and contact finish thickness variations are available across multiple Molex options. Gold-finished contacts (0010897140, 0010897142, 0702800635, 0702800675, 0702871103, 0702871201) provide enhanced corrosion resistance and are suitable for applications requiring long-term reliability in corrosive environments. Tin-finished contacts (0010897141, 0702800595, 0702871005) are suitable for standard applications. Selection should align with the mating connector specification and environmental requirements.

Q: Is the Preci-Dip 450-V3-214-00-006101 a suitable substitute?

A: The Preci-Dip 450-V3-214-00-006101 maintains the 14-position, 2-row, 2.54mm pitch configuration and is mechanically compatible. However, it features circular contacts (versus square), PCT/Polyester insulation (versus LCP), and higher voltage rating (150VDC versus 30VAC). This part is suitable for applications requiring enhanced voltage performance and extended operating temperature range (-55°C to 125°C). Verify that the mating connector accepts circular contacts before selection.

Q: What is the significance of the contact post length variation?

A: Contact post length determines the depth of solder penetration into the circuit board through-hole. Standard post lengths (0.107" to 0.125") are suitable for standard PCB thickness and through-hole depth. Extended post lengths (0.175") accommodate thicker circuit boards or deeper through-hole requirements. Measure the target circuit board through-hole depth and select the appropriate post length to ensure proper solder joint formation and mechanical retention.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed (Molex C-Grid 70280, 70287, and Preci-Dip 450 series) are ROHS3 compliant. The original TE Connectivity 146255-7 is RoHS non-compliant. Selection of any substitute part eliminates RoHS compliance issues for new designs or product updates.

Q: What is the inventory status of substitute parts?

A: All substitute parts listed are active products with current manufacturing status and available inventory. Molex C-Grid 70280 series parts range from 835 to 6964 pieces in stock. Molex C-Grid 70287 series parts range from 671 to 1491 pieces in stock. Preci-Dip 450 series has 804 pieces in stock. Verify current availability with component suppliers before final procurement decisions.

Q: Can the 146255-7 be used in new designs?

A: No. The 146255-7 is classified as obsolete and is RoHS non-compliant. New designs should specify active substitute parts from the Molex C-Grid 70280 or 70287 series, or the Preci-Dip 450 series, depending on specific application requirements. This approach ensures long-term component availability, regulatory compliance, and manufacturing continuity.
