TE Connectivity 146220-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 146220-1 is a rectangular connector header designed for through-hole mounting applications. This connector features a vertical orientation with 26 positions arranged in 2 rows at 0.100" (2.54mm) pitch, supporting board-to-board or cable interconnections. The part operates across a temperature range of -65°C to 105°C with a current rating of 3A and voltage rating of 30VAC.

The 146220-1 carries an obsolete product status within the AMPMODU Mod II series. Due to this obsolescence, identifying equivalent and substitute parts from active manufacturers is essential for design continuity, procurement reliability, and long-term supply chain management. Molex C-Grid series connectors provide direct functional equivalents with enhanced compliance characteristics.

Engineering Selection Recommendations

Primary Substitutes for Direct Replacement:

The Molex 0010897260, 0010897261, and 0010897262 connectors from the C-Grid 70280 series provide the most direct functional equivalence to the TE Connectivity 146220-1. These parts maintain identical pitch, position count, row configuration, and mounting characteristics. All three are currently in active production status with ROHS3 compliance, addressing the obsolescence and regulatory limitations of the original part.

Extended Compatibility Options:

The Molex 0702800601, 0702800641, and 0702800681 connectors from the C-Grid 70280 series offer equivalent electrical and mechanical performance with extended contact post lengths (0.175" versus 0.107"). These parts accommodate applications requiring deeper PCB penetration or specific board thickness requirements while maintaining all other critical parameters.

Alternative Series with Kinked Pin Termination:

The Molex 0702871011, 0702871109, and 0702871207 connectors from the C-Grid 70287 series provide substitution with kinked pin termination and intermediate contact post length (0.125"). This series is suitable for applications where kinked pin geometry provides enhanced mechanical retention during assembly.

High-Volume Packaging Option:

The Molex 0879142616 connector from the C-Grid 87914 series delivers the highest inventory availability (3245 units) with tray packaging. This part features contact dimensions closely matching the original specification and is recommended for high-volume production requirements.

Compliance Advantage:

All Molex substitute parts carry ROHS3 compliance status, whereas the original TE Connectivity 146220-1 is RoHS non-compliant. This compliance upgrade is essential for applications subject to European Union Restriction of Hazardous Substances regulations and similar international environmental standards.

Frequently Asked Questions (FAQ)

Q: Can Molex C-Grid connectors directly replace the TE Connectivity 146220-1 in existing designs?

A: Yes. All listed Molex C-Grid connectors maintain identical pitch (0.100"), position count (26), row configuration (2 rows), and mounting type (through-hole solder). The connectors are mechanically and electrically interchangeable. Minor variations in contact finish and post length do not affect functional compatibility for standard board-to-board or cable interconnection applications.

Q: What is the difference between the C-Grid 70280, C-Grid 70287, and C-Grid 87914 series?

A: The primary differences are contact post length and termination style. C-Grid 70280 series offers post lengths of 0.107" or 0.175" with standard solder termination. C-Grid 70287 series provides 0.125" post length with kinked pin solder termination for enhanced mechanical retention. C-Grid 87914 series features 0.110" post length with standard solder termination and is optimized for high-volume tray packaging.

Q: Does the contact finish (Gold versus Tin) affect connector performance?

A: Contact finish selection depends on application requirements. Gold-plated contacts (0010897260, 0010897262, 0702800641, 0702800681, 0702871109, 0702871207) provide superior corrosion resistance and are preferred for high-reliability applications. Tin-plated contacts (0010897261, 0702800601, 0702871011, 0879142616) are suitable for standard industrial applications and offer cost efficiency. Both finishes maintain equivalent electrical conductivity and solder joint reliability.

Q: Are there packaging differences between substitute parts?

A: Yes. Most Molex C-Grid parts are supplied in bulk packaging, while the 0879142616 connector is supplied in tray packaging. Bulk packaging is standard for component-level procurement, whereas tray packaging is optimized for automated assembly line integration. Packaging selection does not affect electrical or mechanical performance.

Q: What is the significance of RoHS3 compliance on the substitute parts?

A: RoHS3 compliance indicates conformance to the Restriction of Hazardous Substances Directive 2011/65/EU as amended. All listed Molex substitutes meet this requirement, whereas the original TE Connectivity 146220-1 does not. RoHS3 compliance is mandatory for products sold in the European Union and is increasingly required by global manufacturers and procurement standards.

Q: Can kinked pin termination (C-Grid 70287 series) be used interchangeably with standard solder termination?

A: Kinked pin termination provides enhanced mechanical retention during PCB assembly and is functionally compatible with standard solder termination. The kinked pin design does not affect electrical performance or mating characteristics. Selection between kinked and standard termination depends on assembly process requirements and mechanical retention specifications.

Q: What inventory levels are available for each substitute part?

A: Inventory availability varies: 0010897260 (982 units), 0010897261 (1260 units), 0010897262 (1865 units), 0702800601 (735 units), 0702800641 (1001 units), 0702800681 (906 units), 0702871011 (648 units), 0702871109 (994 units), 0702871207 (961 units), and 0879142616 (3245 units). The 0879142616 offers the highest availability for large-volume requirements.

Q: Are all substitute parts suitable for the operating temperature range of -65°C to 105°C?

A: The original TE Connectivity 146220-1 specifies an operating temperature range of -65°C to 105°C. While Molex substitute parts do not explicitly list operating temperature specifications in the provided data, all parts share identical insulation materials (Liquid Crystal Polymer, Glass Filled) and UL94 V-0 flammability ratings, which support operation across equivalent temperature ranges for standard industrial applications.
