Molex 0901200773 Equivalent & Substitute Parts

Part Overview

The Molex 0901200773 is an active rectangular connector header designed for through-hole mounting applications. This 13-position, 2.54mm pitch connector is commonly used in board-to-board and cable interconnect applications across automotive and general-purpose electronics. Substitute parts may be required due to inventory constraints, design revisions, or application-specific performance requirements while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following critical parameters:

Number of Positions: Must be 13
Pitch - Mating: Must be 0.100" (2.54mm)
Connector Type: Header configuration
Contact Type: Male Pin
Mounting Type: Through Hole
Termination: Solder
Material Flammability Rating: UL94 V-0

The substitute parts listed below meet these core electrical and mechanical requirements. Parts with differing position counts or pitch specifications are not interchangeable and are excluded from this analysis.

Engineering Selection Recommendations

All listed substitute parts maintain active product status and meet UL94 V-0 flammability requirements. Selection between the Molex 0901200773 and its substitutes should be based on the following considerations:

TE Connectivity 1-826629-3: Maintains gold mating contact finish consistent with the primary part. Operating temperature range is reduced to -65°C ~ 105°C. Suitable for applications within this thermal envelope.

Harwin M20-9991345 and M20-9991346: Both feature cuttable header design with identical 13-position, 2.54mm pitch configuration. M20-9991345 provides gold mating contact finish; M20-9991346 provides tin mating contact finish. Operating temperature range is -40°C ~ 105°C. Both are ROHS3 compliant and carry 3A per contact current rating.

All substitute parts are ROHS compliant and maintain Moisture Sensitivity Level 1 (Unlimited). Selection should account for specific thermal requirements and contact finish specifications of the target application.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-826629-3 be used as a direct replacement for the Molex 0901200773?

A: The TE Connectivity 1-826629-3 meets the core electrical and mechanical substitution criteria: 13 positions, 2.54mm pitch, male pin header, through-hole solder termination, and UL94 V-0 rating. However, the operating temperature range is reduced from -55°C ~ 125°C to -65°C ~ 105°C. Verify that your application operates within the -65°C ~ 105°C window before substitution.

Q: What is the difference between the Harwin M20-9991345 and M20-9991346?

A: Both parts are mechanically and electrically identical 13-position, 2.54mm pitch headers with identical dimensions and current ratings. The primary difference is contact finish: M20-9991345 features gold mating contact finish, while M20-9991346 features tin mating contact finish. Select based on your application's contact finish requirements.

Q: Why is the TE Connectivity 9-146280-0 not listed as a substitute?

A: The TE Connectivity 9-146280-0 is a 40-position connector header, not a 13-position header. Position count is a critical non-negotiable parameter for substitution. This part is not interchangeable with the Molex 0901200773.

Q: Are all substitute parts available in the same packaging as the Molex 0901200773?

A: The Molex 0901200773 is supplied in Tray packaging. TE Connectivity 1-826629-3 and both Harwin M20 parts are supplied in Bulk packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Do all substitute parts meet the same compliance standards?

A: All listed substitutes are UL94 V-0 rated and RoHS compliant. The Molex 0901200773, Harwin M20-9991345, and Harwin M20-9991346 are ROHS3 compliant. The TE Connectivity 1-826629-3 is RoHS compliant. All parts carry Moisture Sensitivity Level 1 (Unlimited). Verify compliance requirements for your specific application and region.
