Molex 0901200796 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Molex 0901200796 is a vertical through-hole rectangular connector header with 36 positions at 2.54mm pitch, designed for board-to-board or cable applications. This connector features male pins with gold-plated mating contacts and tin-plated posts, housed in a polyester glass-filled insulation body rated UL94 V-0. The part is currently active in production with 874 units in stock.

Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design requirements permit alternative connector series that maintain electrical and mechanical compatibility within specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0901200796 is determined by strict adherence to the following critical parameters:

Primary Compatibility Criteria:

• Number of Positions: 36 (exact match required)
• Pitch - Mating: 0.100" (2.54mm) (exact match required)
• Contact Type: Male Pin (exact match required)
• Mounting Type: Through Hole (exact match required)
• Termination: Solder (exact match required)
• Connector Style: Board to Board or Cable (exact match required)

Secondary Compatibility Parameters:

• Operating Temperature Range: Must encompass or equal the original specification
• Material Flammability Rating: UL94 V-0 (exact match required)
• RoHS Compliance Status: ROHS3 Compliant or equivalent regulatory compliance
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Parts that deviate from these parameters—including position count, pitch spacing, contact configuration, or temperature range—are not suitable substitutes and do not meet the electrical and mechanical requirements for direct replacement.

Parameter Comparison

Engineering Selection Recommendations

Recommended Primary Substitutes (36-Position, Active Status):

TE Connectivity 3-826629-6 is the preferred substitute when supply of the Molex 0901200796 is constrained. This part maintains 36-position configuration, 2.54mm pitch, and through-hole solder termination. Both parts are ROHS3 compliant and carry UL94 V-0 flammability ratings. The TE Connectivity part operates across -65°C to 105°C, which encompasses the lower temperature bound of the original specification but does not extend to the original 125°C maximum. Design applications requiring operation above 105°C must retain the Molex part.

Harwin M20-9993645 and M20-9993646 are functionally equivalent alternatives with identical 36-position, 2.54mm pitch configuration. Both are ROHS3 compliant and UL94 V-0 rated. The M20-9993645 features gold-plated mating contacts matching the original specification, while the M20-9993646 uses tin plating. Both operate to 105°C maximum, limiting use in applications requiring the original -55°C to 125°C range. The Harwin M20-9733646 provides identical electrical and mechanical compatibility with tin-plated mating contacts and equivalent temperature performance.

Not Recommended:

TE Connectivity 4-103185-0 deviates from the primary specification with 40 positions instead of 36, making it unsuitable for direct replacement. Additionally, this part carries obsolete product status and lacks current RoHS compliance documentation, presenting supply and regulatory risk.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 3-826629-6 replace the Molex 0901200796 in all applications?

A: The TE Connectivity 3-826629-6 is mechanically and electrically compatible for applications operating within -65°C to 105°C. Applications requiring operation above 105°C or below -65°C must use the original Molex part or verify thermal performance requirements with the connector manufacturer.

Q: What is the difference between the Harwin M20-9993645 and M20-9993646?

A: Both parts are identical in electrical and mechanical configuration with 36 positions at 2.54mm pitch. The primary difference is contact finish: M20-9993645 features gold-plated mating contacts, while M20-9993646 uses tin-plated mating contacts. Selection depends on application requirements for contact resistance and corrosion performance.

Q: Why is the TE Connectivity 4-103185-0 listed as a substitute if it has 40 positions?

A: The TE Connectivity 4-103185-0 is not a suitable substitute due to the 40-position configuration, which does not match the 36-position requirement of the original part. This part is included in the reference data but does not meet substitution criteria.

Q: Are all substitute parts RoHS compliant?

A: The Molex 0901200796, TE Connectivity 3-826629-6, and all Harwin M20 series parts are RoHS compliant. The TE Connectivity 4-103185-0 carries "Not applicable" RoHS status and should not be used in applications requiring RoHS compliance documentation.

Q: What is the moisture sensitivity level for these connectors?

A: All listed parts, including the main part and all substitutes, carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
