Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0513820304 is determined by alignment with the following critical parameters:

• Manufacturer: Molex (same manufacturer ensures design compatibility within the MicroClasp 51382 series)
• Base Product Number: 051382 (indicates membership in the same connector family)
• Pitch: 0.079" (2.00mm) (electrical and mechanical interface standard)
• Number of Positions: 3 (circuit count requirement)
• Connector Type: Receptacle housing (functional role in the assembly)
• Contact Termination: Crimp (assembly method compatibility)
• Fastening Type: Latch Lock (mechanical engagement standard)
• Insulation Material: Polyamide (PA66), Nylon 6/6 (material specification)
• Operating Temperature Range: -40°C ~ 105°C (thermal performance envelope)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)

The substitute part maintains electrical and mechanical compatibility through shared series designation, pitch specification, position count, and termination method.

Engineering Selection Recommendations

Primary Substitute: Molex 0513820300

The Molex 0513820300 is the manufacturer-recommended substitute for the obsolete 0513820304. Both components share the same base product number (051382) and belong to the MicroClasp connector series. The substitute maintains the 3-position, 2.00mm pitch configuration required for electrical and mechanical compatibility.

Product Status Consideration: The 0513820304 is obsolete with limited remaining inventory (699 pcs). The 0513820300 is active-production with substantial inventory availability (72,764 pcs), ensuring long-term supply chain viability.

Compliance Status: Both parts meet RoHS requirements. The substitute carries ROHS3 compliance, representing current regulatory standards. Both components are classified under ECCN EAR99, maintaining export control consistency.

Packaging: The substitute is supplied in bulk packaging, suitable for manufacturing and assembly operations. The original part packaging specification was not provided.

Frequently Asked Questions (FAQ)

Q: Why is the Molex 0513820304 being discontinued?

A: The 0513820304 is designated as obsolete. Molex has transitioned to active-production alternatives within the MicroClasp 51382 series, including the 0513820300, which provides equivalent functionality with improved supply chain availability.

Q: Is the Molex 0513820300 a direct replacement for the 0513820304?

A: Yes. Both components share the same base product number (051382), maintain identical pitch (2.00mm) and position count (3), and are designed for the same connector family. The 0513820300 is the manufacturer-recommended substitute.

Q: What are the key compatibility parameters between these parts?

A: Compatibility is determined by: manufacturer (Molex), base product series (051382), pitch specification (2.00mm), position count (3), connector type (receptacle housing), contact termination method (crimp), and fastening mechanism (latch lock). Both parts meet these criteria.

Q: Does the substitute part require different contacts or termination methods?

A: No. The 0513820300 uses the same crimp termination method as the original part. Contacts are not included with either housing and must be sourced separately. Existing contact inventory remains compatible.

Q: Are there any temperature or environmental differences between the parts?

A: The substitute specifies an operating temperature range of -40°C to 105°C. The original part's temperature specification was not provided. The substitute's moisture sensitivity level is rated as MSL 1 (unlimited), indicating no moisture-related handling restrictions during storage or assembly.

Q: What is the inventory status for each part?

A: The original 0513820304 has 699 pieces available. The substitute 0513820300 has 72,764 pieces in stock, providing significantly greater availability for current and future production requirements.

Q: Are both parts RoHS compliant?

A: Yes. The original part is RoHS compliant. The substitute carries ROHS3 compliance, representing the current regulatory standard. Both parts are classified under ECCN EAR99 for export control purposes.
