Molex 0901220140 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0901220140 is an active-status rectangular connector header designed for through-hole, right-angle board-to-board or cable applications. This 40-position, 2-row connector with 0.100" (2.54mm) pitch serves general purpose and automotive applications. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when specific performance characteristics of alternative designs are required for system requirements.

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connectors in this category is determined by strict alignment of the following parameters:

Connector type (Header, Breakaway)
Contact type (Male Pin)
Position count and row configuration (40 positions, 2 rows)
Mating pitch and row spacing (0.100" / 2.54mm)
Mounting method (Through Hole, Right Angle)
Termination type (Solder)
Fastening mechanism (Push-Pull)
Contact geometry (Square)
Flammability compliance (UL94 V-0)
RoHS compliance status (ROHS3 Compliant)

The TE Connectivity AMP Connectors part number 2-826634-0 meets all mandatory substitution criteria. Variations in contact finish, insulation material, and dimensional tolerances within acceptable ranges do not preclude substitution eligibility.

Engineering Selection Recommendations

Both the Molex 0901220140 and TE Connectivity 2-826634-0 maintain active product status and full ROHS3 compliance. Selection between these parts should be based on:

Availability and lead time requirements
Contact finish requirements (tin versus gold mating surface)
Insulation material compatibility with application environment
Operating temperature range specifications (TE part rated -65°C ~ 105°C)
Current rating requirements (TE part rated 5A)
Packaging format preference (Molex supplied in Tray; TE supplied in Bulk)

Both connectors satisfy UL94 V-0 flammability requirements and unlimited moisture sensitivity classification, making them suitable for general purpose and automotive applications where specified.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 2-826634-0 be used as a direct replacement for the Molex 0901220140?

A: Yes, the TE Connectivity part meets all mandatory substitution criteria: identical position count, pitch, row configuration, mounting type, termination method, and fastening mechanism. Dimensional variations in contact length and insulation height are within acceptable tolerance ranges for this connector category.

Q: What are the differences in contact finish between these two parts?

A: The Molex part features tin plating on mating contacts, while the TE part features gold plating. Gold plating provides enhanced corrosion resistance and lower contact resistance, which may be beneficial in high-reliability or corrosive environments.

Q: Are there differences in insulation material?

A: Yes. The Molex part uses polyester with glass filler, while the TE part uses polybutylene terephthalate (PBT). Both materials meet UL94 V-0 flammability requirements. PBT offers superior chemical resistance and dimensional stability.

Q: What is the significance of the operating temperature range listed for the TE part?

A: The TE part specifies -65°C ~ 105°C operating temperature. The Molex part does not provide an explicit operating temperature specification in the available data. Applications requiring operation outside standard ambient conditions should reference the complete technical datasheets.

Q: Do packaging differences affect substitution eligibility?

A: Packaging format (Tray versus Bulk) does not affect electrical or mechanical compatibility. Selection should be based on procurement quantity requirements and inventory management practices.

Q: Are both parts suitable for automotive applications?

A: Yes, both parts list automotive applications in their specifications and maintain ROHS3 compliance required for automotive supply chains.
