TE Connectivity 146305-2 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 146305-2 is a rectangular connector header, right-angle configuration, with 2 positions at 0.100" (2.54mm) pitch. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing design and procurement requirements. The connector features through-hole solder termination, unshrouded design, and male pin contacts suitable for board-to-board or cable applications. Due to its obsolete status, substitute parts with equivalent electrical and mechanical characteristics are required for new production and maintenance applications.

Engineering Selection Recommendations

Molex 0901210122 and 0901210762 (C-Grid III 90121 Series)

Both Molex parts are active products with current inventory availability. These connectors meet all primary matching criteria for the TE Connectivity 146305-2. The Molex parts feature ROHS3 compliance and REACH unaffected status, providing regulatory advantages over the obsolete TE part. Contact length variations in the mating interface (0.266" versus 0.318") represent minor dimensional differences that do not affect functional compatibility in standard board-to-board applications. The 0901210122 is packaged in trays, while 0901210762 is supplied in bulk. Selection between these two Molex variants depends on packaging and inventory requirements.

Sullins PBC02SGAN, PBC02SGBN, PEC02SGAN, and PEC02SGBN

All four Sullins parts are active products with ROHS3 compliance and REACH unaffected status. These connectors provide direct functional equivalence to the TE Connectivity 146305-2 across all primary matching parameters. The Sullins parts feature phosphor bronze contact material and polybutylene terephthalate (PBT) insulation, with operating temperature ranges extending to 125°C, exceeding the original part specification. Contact post length variations (0.100" or 0.200") accommodate different PCB thickness requirements. Selection among Sullins variants depends on specific contact finish requirements (gold or tin mating surface) and post length specifications for the application.

Compliance Considerations

All substitute parts are ROHS3 compliant and REACH unaffected, providing regulatory compliance advantages for new designs and production. The original TE Connectivity 146305-2 is RoHS non-compliant and REACH affected, making transition to compliant alternatives necessary for ongoing procurement and design requirements.

Frequently Asked Questions (FAQ)

Q: Can Molex 0901210122 and 0901210762 be used interchangeably with TE Connectivity 146305-2?

A: Both Molex parts meet all primary matching criteria for connector type, contact configuration, pitch, position count, mounting type, and termination method. The primary difference is contact length in the mating interface (0.266" for Molex versus 0.318" for TE). This dimensional variation does not affect functional compatibility in standard board-to-board applications. Selection between the two Molex variants depends on packaging requirements: 0901210122 is supplied in trays, while 0901210762 is supplied in bulk.

Q: What are the key differences between Sullins PBC02SGAN and PBC02SGBN?

A: Both parts are functionally equivalent across all primary matching parameters. The primary difference is contact post length: PBC02SGAN features 0.100" (2.54mm) post length, while PBC02SGBN features 0.200" (5.08mm) post length. Selection depends on PCB thickness and application requirements. Both parts feature gold mating contact finish and tin post finish.

Q: What are the key differences between Sullins PEC02SGAN and PEC02SGBN?

A: Both parts are functionally equivalent across all primary matching parameters. The primary difference is contact post length: PEC02SGAN features 0.100" (2.54mm) post length, while PEC02SGBN features 0.200" (5.08mm) post length. Selection depends on PCB thickness and application requirements. Both parts feature tin mating contact finish and tin post finish.

Q: How do Sullins parts differ from Molex parts?

A: All Sullins and Molex parts meet the primary matching criteria for substitution. Key differences include contact material (Molex uses brass; Sullins uses phosphor bronze), insulation material (Molex uses polyester; Sullins uses PBT), and contact length in the mating interface (Molex 0.266" versus Sullins 0.318"). Sullins parts offer extended operating temperature range to 125°C compared to Molex parts with unspecified temperature ratings. All parts are ROHS3 compliant and REACH unaffected.

Q: What is the significance of contact finish differences (gold versus tin)?

A: Contact finish affects corrosion resistance and electrical performance characteristics. Gold-plated contacts (PBC02SGAN, PBC02SGBN, 0901210762) provide enhanced corrosion resistance and are suitable for applications requiring superior long-term reliability. Tin-plated contacts (PEC02SGAN, PEC02SGBN, 0901210122) are suitable for general-purpose applications with standard environmental conditions. Selection depends on application environment and reliability requirements.

Q: Are all substitute parts available in current inventory?

A: All identified substitute parts are active products with current inventory availability. Molex 0901210122 has 17,424 pieces in stock (tray packaging). Molex 0901210762 has 3,786 pieces in stock (bulk packaging). Sullins parts have inventory ranging from 972 to 1,283 pieces in stock (bulk packaging). Availability should be confirmed with component suppliers for specific procurement timelines.

Q: What compliance advantages do substitute parts offer over the original TE Connectivity 146305-2?

A: All substitute parts are ROHS3 compliant and REACH unaffected, compared to the original part which is RoHS non-compliant and REACH affected. This provides regulatory compliance for new designs and production in jurisdictions with RoHS and REACH requirements. Transition to compliant alternatives is necessary for ongoing procurement and design requirements.
