Key Parameters

Substitute Part Grouping Explanation

Substitution of the 4-146285-0 is determined by strict equivalence across the following critical parameters: connector type (Header, Breakaway), contact type (Male Pin), number of positions (40), mating pitch (0.100"/2.54mm), mounting type (Through Hole), termination method (Solder), fastening type (Push-Pull), current rating (3A), and flammability rating (UL94 V-0).

The primary substitute, TE Connectivity 9-146285-0, maintains identical electrical and mechanical specifications while offering active product status and improved compliance characteristics. Secondary substitutes from alternative manufacturers (3M 2340-6111TG and Sullins Connector Solutions PREC040SAFN-RC) provide functional equivalence with variations in contact post length, insulation material composition, and operating temperature range that remain within acceptable parameters for board-to-board and cable connector applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TE Connectivity 9-146285-0

The 9-146285-0 is the direct equivalent of the obsolete 4-146285-0, maintaining identical electrical and mechanical specifications across all critical parameters. This part offers active product status with improved regulatory compliance, including RoHS Compliant certification and REACH Unaffected status. The contact finish on the post is tin rather than tin-lead, eliminating lead content while preserving electrical performance. This substitute is the preferred selection for direct replacement in existing designs.

Secondary Substitute: 3M 2340-6111TG

The 2340-6111TG provides functional equivalence with variations in contact post length (0.120" versus 0.090"), overall contact length (0.450" versus 0.410"), and insulation height (0.100" versus 0.090"). The operating temperature range is reduced to -55°C ~ 105°C. This part maintains active product status and UL94 V-0 flammability rating. Selection of this substitute requires verification that the increased contact post length and modified insulation dimensions are compatible with the target PCB layout and mating connector specifications.

Tertiary Substitute: Sullins Connector Solutions PREC040SAFN-RC

The PREC040SAFN-RC offers functional equivalence with significant variations in contact post length (0.620" versus 0.090"), overall contact length (0.948" versus 0.410"), and insulation material (PBT versus LCP). The mating contact finish is tin rather than gold. The operating temperature range is reduced to -40°C ~ 105°C. This part provides active product status with ROHS3 Compliant and REACH Unaffected certifications. Selection of this substitute requires confirmation that the extended contact post length accommodates the application's PCB thickness and mating connector design.

Frequently Asked Questions (FAQ)

Q: Can the 9-146285-0 be used as a direct replacement for the 4-146285-0?

A: Yes. The 9-146285-0 maintains identical electrical and mechanical specifications with the 4-146285-0 across all critical parameters including connector type, contact type, number of positions, mating pitch, mounting type, termination method, and current rating. The primary difference is product status (Active versus Obsolete) and improved regulatory compliance.

Q: What are the key differences between the TE Connectivity 9-146285-0 and the 3M 2340-6111TG?

A: Both parts share identical mating pitch (0.100"/2.54mm), number of positions (40), and current rating (3A). The 2340-6111TG differs in contact post length (0.120" versus 0.090"), overall contact length (0.450" versus 0.410"), insulation height (0.100" versus 0.090"), insulation material (Thermoplastic, Glass Filled versus LCP), and operating temperature range (-55°C ~ 105°C versus -65°C ~ 105°C). These differences may affect PCB layout compatibility and thermal performance in extreme cold environments.

Q: Why does the Sullins PREC040SAFN-RC have a significantly longer contact post?

A: The PREC040SAFN-RC is designed for applications requiring deeper PCB penetration or thicker substrate materials. The 0.620" post length accommodates PCB thicknesses up to approximately 0.500" with adequate solder joint formation. This extended length is not compatible with standard 0.062" PCB applications without modification to the mating connector or PCB design.

Q: Are there compliance differences between these substitutes?

A: Yes. The 4-146285-0 is RoHS non-compliant and REACH Affected. The 9-146285-0 is RoHS Compliant and REACH Unaffected. The 2340-6111TG is RoHS non-compliant and REACH Affected. The PREC040SAFN-RC is ROHS3 Compliant and REACH Unaffected. Selection should consider regulatory requirements for the target application and end-use market.

Q: Can the mating contact finish differences affect connector performance?

A: The 4-146285-0 and 9-146285-0 feature gold-plated mating contacts (30.0µin thickness). The 2340-6111TG also features gold-plated mating contacts (10.0µin thickness). The PREC040SAFN-RC features tin-plated mating contacts. Gold plating provides superior corrosion resistance and lower contact resistance. Tin plating is acceptable for standard applications but may exhibit higher contact resistance in high-reliability or high-frequency applications.

Q: What packaging options are available?

A: The 4-146285-0 is supplied in standard packaging. The 9-146285-0, 2340-6111TG, and PREC040SAFN-RC are supplied in Bulk packaging, suitable for high-volume production and automated assembly processes.

Q: Which substitute is recommended for new designs?

A: For new designs requiring maximum compatibility with existing connector ecosystems and regulatory compliance, the TE Connectivity 9-146285-0 is the recommended selection. It provides active product status, identical mechanical and electrical specifications, and improved compliance certifications. Alternative substitutes should be selected only when specific application requirements (such as extended contact post length or alternative insulation materials) necessitate their use.
