Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0511630488 is determined by strict equivalence across the following critical parameters:

• Series Compatibility: Both parts must belong to the Mini-Lock 51163 connector series
• Connector Configuration: Receptacle housing with 4 positions
• Electrical Interface: 0.098" (2.50mm) pitch with female socket contacts
• Mechanical Interface: Free hanging (in-line) mounting with crimp termination and latch lock fastening
• Material Specification: Polybutylene Terephthalate (PBT) insulation
• Thermal Performance: Operating temperature range of -40°C to 105°C

The substitute part 0511630488 meets all these criteria, with the primary distinction being product status (active versus obsolete) and color variation (natural versus orange).

Parameter Comparison

Engineering Selection Recommendations

The Molex 0511630400 is the direct functional equivalent for the obsolete 0511630488. Both housings are electrically and mechanically identical across all critical interface parameters. The 0511630400 is the manufacturer-recommended substitute, offering the following advantages:

• Active Product Status: The 0511630400 maintains active production status with established supply chain availability (58,165 units in stock versus 928 for the obsolete part)
• Regulatory Compliance: The substitute carries ROHS3 compliance certification and REACH unaffected status, meeting current environmental and regulatory requirements
• Moisture Sensitivity: Defined MSL rating (Level 1, Unlimited) versus vendor-undefined specification on the original part
• Color Differentiation: The natural color of the substitute part does not affect electrical or mechanical function; color selection should be based on application-specific requirements or assembly documentation

Selection of the 0511630400 is appropriate for new designs, system upgrades, and replacement applications where the obsolete 0511630488 is no longer procurable.

Frequently Asked Questions (FAQ)

Q: Are the 0511630488 and 0511630400 electrically interchangeable?

A: Yes. Both housings feature identical electrical specifications: 4-position receptacle configuration, 0.098" (2.50mm) pitch, female socket contacts, and -40°C to 105°C operating range. They are designed for the same mating connector interfaces within the Mini-Lock 51163 series.

Q: Does the color difference between orange (0511630488) and natural (0511630400) affect compatibility?

A: No. Color is a visual identifier only and does not affect electrical performance, mechanical fit, or thermal characteristics. Color selection should follow application documentation or assembly requirements.

Q: What is the significance of the product status difference?

A: The 0511630488 is classified as obsolete, indicating discontinued production and limited remaining inventory. The 0511630400 maintains active status with ongoing manufacturing support. For new procurements and long-term supply assurance, the active part is the appropriate choice.

Q: Why does the 0511630400 have a defined MSL rating while the 0511630488 does not?

A: The MSL (Moisture Sensitivity Level) specification reflects current manufacturing and documentation standards. The 0511630400's Level 1 rating (Unlimited) indicates the component has minimal moisture sensitivity and requires no special handling precautions. This represents standard practice for modern connector housings.

Q: Can the 0511630400 be used as a direct replacement in existing assemblies?

A: Yes, provided the application does not have specific color-coding requirements. The mechanical and electrical interfaces are identical, allowing direct substitution in PCB assemblies, harnesses, and connector systems designed for the Mini-Lock 51163 series.
