Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4-146280-0 is determined by the following critical parameters: connector type (header with breakaway capability), contact type (male pin), number of positions (40), mating pitch (0.100" / 2.54mm), mounting method (through hole), termination type (solder), current rating (3A), and operating temperature range (-65°C ~ 105°C). Additional compatibility factors include contact finish (gold mating surface), insulation material properties, and flammability certification (UL94 V-0).

The substitute parts identified maintain these core electrical and mechanical specifications. Variations in secondary parameters such as contact finish thickness on the post, insulation height, and overall contact length do not preclude functional substitution when these variations remain within standard manufacturing tolerances and do not affect mating interface geometry or electrical performance.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TE Connectivity 9-146280-0

The 9-146280-0 represents the direct active equivalent to the obsolete 4-146280-0. Both components are manufactured by TE Connectivity within the AMPMODU Mod II series and maintain identical electrical and mechanical specifications. The 9-146280-0 is currently in active production status with significantly higher inventory availability (2880 pieces). This part achieves RoHS compliance and REACH unaffected status, addressing regulatory requirements that the original part does not satisfy. The contact finish on the post differs only in composition (Tin versus Tin-Lead), which does not affect functional compatibility. This substitute is the preferred selection for new designs and ongoing procurement.

Secondary Substitute: 3M 2340-6111TG

The 2340-6111TG from 3M's 2300 series provides functional equivalence with measurable differences in secondary parameters. This connector maintains the same 40-position, 0.100" pitch configuration with identical contact types, mounting method, and current rating. The operating temperature range is reduced to -55°C ~ 105°C (versus -65°C ~ 105°C), which may be acceptable depending on application requirements. The insulation material differs (thermoplastic, glass filled versus liquid crystal polymer), and the overall contact length is 0.450" (11.43mm) compared to 0.440" (11.18mm). The insulation height is 0.100" (2.54mm) versus 0.090" (2.29mm). These dimensional variations require verification of PCB layout compatibility and mating interface clearances. The 2340-6111TG maintains UL94 V-0 flammability certification and unlimited moisture sensitivity rating. This part is suitable for applications where the reduced temperature range and alternative insulation material are acceptable.

Frequently Asked Questions (FAQ)

Q: Can the 9-146280-0 be used as a direct replacement for the 4-146280-0 without PCB modifications?

A: Yes. The 9-146280-0 maintains identical mating contact geometry, pitch, number of positions, and mounting hole pattern. No PCB layout modifications are required for substitution.

Q: What is the significance of the RoHS compliance difference between 4-146280-0 and 9-146280-0?

A: The 9-146280-0 is RoHS compliant, indicating the elimination of restricted substances (lead, cadmium, hexavalent chromium, and others) from the component composition. The 4-146280-0 is RoHS non-compliant due to the presence of lead in the tin-lead contact finish. For applications subject to RoHS regulations or customer requirements, the 9-146280-0 is the appropriate selection.

Q: Are there any electrical performance differences between the TE Connectivity and 3M substitutes?

A: Both substitutes maintain the same 3A current rating, gold mating contact finish, and copper alloy contact material. Electrical performance is equivalent for standard applications. The 3M 2340-6111TG uses a different insulation material (thermoplastic, glass filled) compared to the liquid crystal polymer used in TE Connectivity parts, but this does not affect electrical performance within the specified operating parameters.

Q: What is the impact of the operating temperature range difference in the 3M 2340-6111TG?

A: The 3M part operates from -55°C to 105°C, whereas the TE Connectivity parts operate from -65°C to 105°C. The 3M substitute cannot be used in applications requiring operation below -55°C. For applications with minimum operating temperatures at or above -55°C, the 3M part is suitable.

Q: How do the dimensional differences in the 3M 2340-6111TG affect compatibility?

A: The 3M part has an overall contact length of 0.450" (11.43mm) and insulation height of 0.100" (2.54mm), compared to 0.440" (11.18mm) and 0.090" (2.29mm) respectively for the TE Connectivity parts. These differences may affect mating interface clearances and stacking height in multi-connector applications. PCB layout and mating connector specifications must be reviewed to confirm compatibility.

Q: What is the difference between the contact finish specifications listed for the post?

A: The 4-146280-0 and 2340-6111TG use tin-lead finish on the post, while the 9-146280-0 uses tin finish. Both finishes provide equivalent solderability and electrical performance. The tin finish in the 9-146280-0 contributes to its RoHS compliance status.

Q: Is the 9-146280-0 available in the same packaging as the original 4-146280-0?

A: The 9-146280-0 is supplied in bulk packaging, whereas the original part packaging is not specified in the available data. Confirm packaging requirements with the supplier to ensure compatibility with assembly processes.

Q: Can these connectors be used interchangeably in existing assemblies?

A: The 9-146280-0 is fully interchangeable with the 4-146280-0 in existing assemblies. The 3M 2340-6111TG requires verification of dimensional compatibility with the mating connector and PCB layout before implementation in existing designs.
