Molex 0901220140 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0901220140 is a right-angle rectangular connector header designed for through-hole mounting applications. This 40-position, 2-row connector with 0.100" (2.54mm) pitch is classified as an active product with full inventory availability. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design flexibility permits component interchange based on electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector headers is determined by strict alignment of core mating and mechanical parameters. The following criteria establish functional interchangeability:

Critical Parameters for Substitution:

• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 40
• Number of Rows: 2
• Row Spacing - Mating: 0.100" (2.54mm)
• Contact Type: Male Pin
• Mounting Type: Through Hole, Right Angle
• Termination: Solder
• Connector Type: Header, Breakaway

The substitute part TE Connectivity AMP Connectors 2-826634-0 meets all critical mating and mechanical parameters, establishing direct functional equivalence for board-to-board or cable applications requiring 40-position, 2.54mm pitch header connectivity.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0901220140 and TE Connectivity 2-826634-0 are active products with ROHS3 compliance and UL94 V-0 flammability ratings. Selection between these parts should be based on:

Compliance and Certification: Both parts meet identical regulatory requirements (ROHS3, UL94 V-0, MSL 1). No compliance-based differentiation exists.

Mechanical Fit: Minor dimensional variations exist in contact length and insulation height. The TE Connectivity substitute exhibits a 0.002" (0.05mm) shorter mating contact length and 0.023" (0.58mm) lower insulation height. These variations remain within typical connector tolerance ranges for standard board-to-board applications.

Contact Finish: The Molex part features tin-plated mating contacts, while the TE Connectivity substitute uses gold-plated mating contacts. Gold plating provides enhanced corrosion resistance and contact reliability in high-reliability applications.

Insulation Material: The Molex part uses polyester with glass fill; the TE Connectivity part uses PBT. Both materials provide equivalent mechanical and thermal performance for standard applications.

Inventory Availability: The TE Connectivity substitute (2820 pcs) offers higher stock availability compared to the Molex part (1042 pcs).

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 2-826634-0 directly replace the Molex 0901220140 in existing designs?

A: Yes. Both connectors share identical mating pitch (0.100"), position count (40), row configuration (2 rows), and mounting orientation (through-hole, right-angle). The connectors are mechanically and electrically interchangeable for standard board-to-board applications.

Q: What are the dimensional differences between these connectors?

A: The TE Connectivity substitute has a mating contact length of 0.264" (6.70mm) versus 0.266" (6.75mm) for the Molex part, and an insulation height of 0.219" (5.56mm) versus 0.242" (6.14mm). These differences are minor and do not affect standard PCB mounting or mating operations.

Q: Does the gold plating on the TE Connectivity connector provide any performance advantage?

A: Gold-plated contacts offer improved corrosion resistance and contact reliability compared to tin plating, particularly in environments with elevated humidity or corrosive atmospheres. For standard indoor applications, both finishes provide equivalent performance.

Q: Are both connectors RoHS compliant?

A: Yes. Both the Molex 0901220140 and TE Connectivity 2-826634-0 are ROHS3 compliant and carry UL94 V-0 flammability ratings.

Q: What is the difference in insulation material between these connectors?

A: The Molex part uses polyester with glass fill, while the TE Connectivity substitute uses PBT (polybutylene terephthalate). Both materials provide equivalent mechanical strength and thermal performance for standard applications.

Q: Can these connectors be used interchangeably in high-temperature applications?

A: Operating temperature data is not provided for the Molex part. The TE Connectivity substitute is rated for -65°C to 105°C. Verify the Molex part's temperature rating against your application requirements before selecting either connector.
