TE Connectivity 146308-6 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 146308-6 is a rectangular connector header manufactured under the AMPMODU Mod II series. This through-hole, right-angle connector features 12 positions across 2 rows with 0.100" (2.54mm) pitch spacing and is designed for board-to-board or cable applications. The part is classified as obsolete, which necessitates identification of active equivalent and substitute components for ongoing design and procurement requirements. Equivalent parts maintain functional compatibility while substitute parts offer alternative solutions with comparable electrical and mechanical characteristics.

Engineering Selection Recommendations

Primary Equivalent (Same Manufacturer):

The TE Connectivity 5-146308-6 is the direct equivalent replacement for the obsolete 146308-6. Both parts share identical electrical and mechanical specifications within the AMPMODU Mod II series. The 5-146308-6 is currently in active production status with 974 units in stock. The primary distinction is RoHS compliance: the 5-146308-6 is RoHS Compliant, whereas the original 146308-6 is RoHS non-compliant. This upgrade path is recommended for new designs and legacy system updates requiring regulatory compliance.

Cross-Manufacturer Alternatives:

For applications where multi-source qualification is required or where TE Connectivity parts are unavailable, the following active alternatives meet the core functional parameters:

Amphenol ICC (FCI) 79257-112HLF (BERGSTIK® II series) provides direct functional compatibility with identical contact length specifications and gold mating finish. This part is RoHS Compliant and operates across an extended temperature range (-65°C to 130°C). The insulation height is reduced to 0.190" (4.83mm), which may affect board layout compatibility in space-constrained applications.

Sullins Connector Solutions PBC06DBAN and PEC06DBAN offer active alternatives with ROHS3 Compliance. Both parts feature identical contact mating length (0.230") and current rating (3A). The PBC06DBAN uses gold mating finish with tin post finish, while PEC06DBAN uses tin for both mating and post finishes. Contact post length is reduced to 0.100" (2.54mm) compared to the original 0.120" (3.05mm), requiring verification of PCB hole depth compatibility.

Molex 0901220126 (C-Grid III 90122 series) is an active alternative with ROHS3 Compliance. This part features a longer mating contact length (0.266" vs. 0.230") and tin mating finish. Operating temperature range is not specified in available documentation. Brass contact material differs from the copper alloy specification of the original part.

3M 2312-5121TG maintains identical contact specifications and gold mating finish but is RoHS non-compliant, limiting its use in new designs subject to regulatory requirements. Operating temperature range is -55°C to 105°C, which does not extend to the full -65°C lower limit of the original specification.

Compliance Considerations:

For applications requiring RoHS compliance, the TE Connectivity 5-146308-6, Amphenol ICC 79257-112HLF, and Sullins PBC06DBAN/PEC06DBAN are qualified selections. For legacy systems without RoHS requirements, the 3M 2312-5121TG and original 146308-6 remain functionally equivalent.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5-146308-6 be used as a direct replacement for the obsolete 146308-6?

A: Yes. The 5-146308-6 is the direct equivalent with identical electrical and mechanical specifications. The primary difference is RoHS compliance status. Both parts are compatible with the same mating connectors and PCB layouts. The 5-146308-6 is currently in active production.

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

A: Contact post length determines the depth of solder engagement in PCB holes. The original 146308-6 specifies 0.120" (3.05mm) post length. Substitute parts with shorter post lengths (such as Sullins PBC06DBAN at 0.100") require verification that PCB hole depth accommodates the reduced engagement length. Insufficient hole depth may result in inadequate solder joint formation.

Q: Are all substitute parts compatible with the same mating connectors as the 146308-6?

A: Compatibility depends on pitch and row spacing alignment. All listed substitutes maintain 0.100" (2.54mm) pitch and 2-row configuration, ensuring mechanical mating compatibility. However, variations in insulation height and contact length may affect electrical performance in specific applications. Physical fit testing is recommended for critical applications.

Q: What is the difference between the Sullins PBC06DBAN and PEC06DBAN parts?

A: Both parts are functionally equivalent with identical dimensions and current ratings. The primary difference is contact finish: PBC06DBAN features gold mating finish with tin post finish, while PEC06DBAN uses tin for both mating and post finishes. Gold mating finish provides superior corrosion resistance and is recommended for applications with extended shelf life or harsh environmental exposure.

Q: Does the Amphenol ICC 79257-112HLF reduced insulation height (0.190" vs. 0.238") affect compatibility?

A: The reduced insulation height may impact board layout compatibility, particularly in applications with tight vertical spacing constraints. The lower profile may allow closer component placement but requires verification that the mating connector and surrounding components do not create mechanical interference. Electrical performance is not affected by this dimensional variation.

Q: Which substitute part offers the best compliance profile for new designs?

A: The TE Connectivity 5-146308-6 is the recommended selection for new designs, as it is the direct equivalent with RoHS Compliance and active production status. For multi-source qualification, the Sullins PBC06DBAN and PEC06DBAN (ROHS3 Compliant) and Amphenol ICC 79257-112HLF (RoHS Compliant) are qualified alternatives.

Q: Are there any temperature range limitations when substituting the 146308-6?

A: The original 146308-6 operates from -65°C to 105°C. Most substitute parts meet or exceed this range. The 3M 2312-5121TG has a lower limit of -55°C, which does not meet the full specification. The Amphenol ICC 79257-112HLF and Sullins alternatives extend to 125°C or 130°C, providing additional thermal margin.

Q: What packaging options are available for the substitute parts?

A: The TE Connectivity 5-146308-6 is supplied in Tray packaging. Amphenol ICC 79257-112HLF is supplied in Bag packaging. Sullins alternatives (PBC06DBAN, PEC06DBAN) are supplied in Bulk packaging. Packaging selection may affect procurement lead times and handling requirements but does not impact electrical or mechanical performance.

Q: Is the Molex 0901220126 a suitable substitute despite the longer contact mating length?

A: The Molex 0901220126 is functionally compatible but features a longer mating contact length (0.266" vs. 0.230"). This variation may affect mating force and electrical contact pressure characteristics. The part is suitable for applications where the extended contact length does not create mechanical interference with the mating connector or surrounding components. Verification testing is recommended for critical applications.
