Molex 0513820804 Equivalent & Substitute Parts

Part Overview

The Molex 0513820804 is a 2.0mm pitch rectangular connector housing designed for 8-circuit applications in the WTB (Wire-to-Board) configuration. This component functions as a receptacle housing for the MicroClasp 51382 series connector family. The part is classified as Obsolete, necessitating identification of active equivalent components for ongoing procurement and design applications. Substitute parts must maintain electrical and mechanical compatibility within the rectangular connector housing category while meeting current manufacturing and compliance standards.

Substitute Part Grouping Explanation

The substitute part Molex 0513820800 is designated as the manufacturer-recommended equivalent for the obsolete 0513820804. Substitution eligibility is determined by the following critical parameters:

Substitution Criteria:

• Identical series designation (MicroClasp 51382)
• Matching pitch specification (0.079" / 2.00mm)
• Identical number of positions (8)
• Identical connector type (Receptacle)
• Identical contact type (Female Socket)
• Identical number of rows (1)
• Identical mounting type (Free Hanging In-Line)
• Identical contact termination method (Crimp)
• Identical fastening mechanism (Latch Lock)
• Compatible insulation material (Polyamide PA66 / Nylon 6/6)
• Overlapping operating temperature range (-40°C ~ 105°C)
• Equivalent or superior RoHS compliance status

The primary distinction between the main part and substitute is product status (Obsolete vs. Active) and housing color (Blue vs. White). Both components share the same base product number (051382) and are fully compatible within the MicroClasp connector ecosystem.

Engineering Selection Recommendations

Primary Recommendation: Molex 0513820800

The Molex 0513820800 is the manufacturer-designated substitute for the obsolete 0513820804. Selection of this component is supported by the following engineering factors:

Product Status Justification: The 0513820804 carries an Obsolete designation, indicating discontinued manufacturing and limited availability. The 0513820800 maintains Active product status with substantial inventory (80,156 pieces), ensuring long-term procurement viability and supply chain continuity.

Compliance and Certification: Both components maintain equivalent export control classification (EAR99). The substitute part carries ROHS3 Compliant certification, which supersedes the RoHS Compliant status of the main part, indicating enhanced environmental and regulatory alignment with current manufacturing standards.

Electrical and Mechanical Equivalence: All critical electrical parameters (pitch, number of positions, contact type, termination method) and mechanical specifications (mounting type, fastening mechanism, insulation material, operating temperature range) are identical between the main part and substitute. This equivalence ensures direct functional replacement without circuit redesign or mechanical rework.

Packaging Consideration: The substitute part is supplied in Bulk packaging, which is standard for high-volume procurement applications. The main part packaging designation is not specified in available documentation.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0513820800 be used as a direct replacement for the 0513820804 in existing designs?

A: Yes. The 0513820800 is the manufacturer-recommended substitute and maintains identical electrical and mechanical specifications. All critical parameters including pitch (2.00mm), position count (8), connector type (Receptacle), contact type (Female Socket), termination method (Crimp), and fastening mechanism (Latch Lock) are identical. Direct substitution is supported without design modification.

Q: What is the significance of the color difference between the blue 0513820804 and white 0513820800?

A: Color designation in rectangular connector housings is a cosmetic and identification feature that does not affect electrical or mechanical function. Both colors utilize identical Polyamide (PA66) insulation material and operate within the same temperature range (-40°C ~ 105°C). Color selection is determined by application requirements or design preference.

Q: Are the contacts included with these housing components?

A: No. Both the main part and substitute are housing-only components. The documentation explicitly states "Contacts Not Included." Contacts must be procured separately and crimped into the housing according to Molex specifications for the MicroClasp 51382 series.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: ROHS3 Compliant represents the current iteration of the Restriction of Hazardous Substances directive and includes expanded substance restrictions compared to earlier RoHS versions. The substitute part's ROHS3 certification indicates compliance with the most current environmental standards and is fully compatible with RoHS-compliant applications.

Q: Why is the 0513820804 listed as Obsolete?

A: Obsolete status indicates that the manufacturer has discontinued production of this component. The Molex 0513820800 was introduced as the active replacement, offering identical functionality with current manufacturing support and availability.

Q: What is the Moisture Sensitivity Level (MSL) for these components?

A: The main part (0513820804) lists MSL as Not Applicable. The substitute part (0513820800) carries MSL 1 (Unlimited), indicating minimal moisture sensitivity and no special storage or handling requirements during assembly.

Q: Are these components suitable for high-volume production?

A: Yes. The substitute part maintains substantial inventory (80,156 pieces) and Active product status, supporting high-volume manufacturing requirements. The main part, with 741 pieces in stock and Obsolete status, is not recommended for new production programs.

Q: What is the base product number, and why is it significant?

A: Both components share the base product number 051382, which identifies them as members of the MicroClasp 51382 connector series. This designation confirms their compatibility within the same connector ecosystem and interchangeability of associated contacts and accessories.
