Molex 0901310783 Equivalent & Substitute Parts

Part Overview

The Molex 0901310783 is a rectangular connector header designed for through-hole mounting applications. This C-Grid III 90131 series component features 46 positions arranged in 2 rows with 0.100" (2.54mm) pitch spacing. The connector is actively manufactured and widely used in automotive and general-purpose applications where board-to-cable or board-to-board interconnection is required. Substitute parts may be necessary due to inventory constraints, lead time considerations, or specific application requirements that align with alternative connector specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0901310783 is determined by the following critical parameters:

Primary Matching Criteria:

• Pitch - Mating: 0.100" (2.54mm)
• Number of Rows: 2
• Row Spacing - Mating: 0.100" (2.54mm)
• Connector Type: Header with breakaway or cuttable capability
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

Position Flexibility: The main part specifies 46 positions. Substitute parts may vary in position count while maintaining all other electrical and mechanical parameters, provided the connector maintains the same row configuration and pitch spacing. This allows for application-specific position requirements.

Contact Finish Variations: Substitute parts may differ in contact finish specifications (gold vs. tin mating surfaces) while maintaining compatibility with the core mechanical and electrical interface.

Three substitute parts meet these criteria and are listed below.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active product status and full ROHS3 compliance, ensuring regulatory alignment with the original Molex 0901310783.

Harwin M20-9982345 and M20-9982346 are direct position-count equivalents to the main part, both featuring 46 positions in a 2-row configuration. These parts differ primarily in contact finish specification: M20-9982345 features gold mating contacts, while M20-9982346 features tin mating contacts. Both are manufactured from brass with polyamide insulation and maintain the same pitch and row spacing. Operating temperature range extends to -40°C ~ 105°C with a 3A per contact current rating.

TE Connectivity 9-146256-0 provides an 80-position alternative within the same connector family. This part maintains identical pitch and row spacing but accommodates applications requiring higher position density. The contact material is specified as copper alloy with liquid crystal polymer insulation. Operating temperature range is -65°C ~ 105°C with a 3A current rating.

Selection between these substitutes depends on specific application requirements regarding position count, contact finish preference, and insulation material compatibility.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 9-146256-0 with 80 positions be used as a direct replacement for the 46-position Molex connector?

A: The TE Connectivity part maintains the same pitch (0.100"), row spacing (0.100"), and row count (2) as the main part. However, the increased position count (80 vs. 46) means the overall connector length differs. This part is suitable only for applications where the additional positions can be accommodated or left unused on the PCB layout.

Q: What is the difference between the two Harwin M20 substitutes?

A: Both M20-9982345 and M20-9982346 are identical except for contact finish specification. M20-9982345 features gold mating contacts, while M20-9982346 features tin mating contacts. Both maintain the same 46-position configuration, brass contact material, and polyamide insulation.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and maintain the same regulatory status as the original Molex 0901310783.

Q: What insulation materials are used in the substitute parts?

A: The Molex original uses polyester with glass filling. Harwin substitutes use polyamide (PA6T) nylon 6T. TE Connectivity uses liquid crystal polymer (LCP). All materials maintain UL94 V-0 flammability rating.

Q: Do all parts support the same mounting and termination methods?

A: Yes. All parts are through-hole mounted with solder termination and push-pull fastening type, maintaining mechanical compatibility with the original design.
