Key Parameters

Substitute Part Grouping Explanation

Substitution for the Molex 0513820303 is determined by the following critical parameters:

Pitch Specification: 0.079" (2.0mm) — The connector pitch must match exactly to ensure proper mating with corresponding contact assemblies and cable terminations.

Number of Positions: 3-position configuration — The housing must accommodate exactly three circuits to maintain electrical and mechanical compatibility.

Connector Category: Rectangular Connectors - Housings — The substitute must be a housing component within the same rectangular connector family.

Manufacturer Consistency: Molex — Maintaining the same manufacturer ensures design compatibility and performance characteristics aligned with the original specification.

Series Compatibility: MicroClasp 51382 series — The substitute part belongs to the same product series, ensuring mechanical and electrical interchangeability.

The substitute part Molex 0513820303 meets all these criteria while offering the advantage of Active product status with significantly higher inventory availability.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The original part 0513820303 carries an Obsolete designation, indicating discontinued production and limited future availability. The substitute part 0513820300 maintains Active status with 72,764 units in current inventory, providing reliable long-term supply assurance.

Compliance Alignment: Both parts maintain EAR99 export classification. The substitute part carries ROHS3 Compliant certification, representing current regulatory compliance standards, while the original part is RoHS Compliant. This upgrade in compliance status supports modern manufacturing and environmental requirements.

Series Continuity: Both parts share the base product number 051382 and belong to the MicroClasp 51382 series, confirming mechanical and electrical interchangeability within the Molex rectangular connector housing portfolio.

Specification Matching: The substitute part 0513820300 matches the critical electrical parameters of the original part: 2.0mm pitch and 3-position configuration. These parameters determine connector mating compatibility and circuit capacity.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0513820300 directly replace the 0513820303 in existing designs?

A: Yes. Both parts share identical pitch (2.0mm) and position count (3), which are the primary parameters determining mechanical and electrical compatibility. Both belong to the same MicroClasp 51382 series and are manufactured by Molex.

Q: What is the primary reason for substitution?

A: The original part 0513820303 is Obsolete and no longer in production. The substitute 0513820300 is Active with substantial inventory availability, ensuring supply chain continuity.

Q: Are there packaging differences between these parts?

A: The original part packaging is not specified in the documentation. The substitute part 0513820300 is supplied in Bulk packaging, which is standard for rectangular connector housings.

Q: Do both parts meet current regulatory requirements?

A: Both parts are RoHS compliant. The substitute part carries ROHS3 Compliant certification, representing the current regulatory standard. Both maintain EAR99 export classification.

Q: What is the inventory status difference?

A: The original part has 936 units in stock. The substitute part has 72,764 units in current inventory, providing significantly greater availability for immediate and future procurement needs.

Q: Are the operating temperature ranges specified for both parts?

A: The original part operating temperature is not specified in the documentation. The substitute part operates across -40°C to 105°C, which covers standard industrial and commercial temperature ranges.

Q: Do these parts require contacts to be purchased separately?

A: Yes. The substitute part documentation explicitly notes that contacts are not included with the housing. Contacts must be procured separately and selected based on the specific circuit requirements and termination method.
