Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0511630489 is determined by strict equivalence across the following critical parameters:

• Series compatibility: Mini-Lock 51163
• Connector type: Receptacle housing
• Contact type: Female socket
• Position count: 4 positions
• Pitch specification: 0.098" (2.50mm)
• Row configuration: Single row
• Mounting configuration: Free hanging (in-line)
• Contact termination method: Crimp
• Fastening mechanism: Latch lock
• Insulation material: Polybutylene terephthalate (PBT)
• Operating temperature range: -40°C to 105°C minimum
• Regulatory compliance: Glow wire compliant

The primary substitute identified is the Molex 0511630400, which maintains identical electrical and mechanical specifications while differing only in housing color and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0511630400 is the direct functional equivalent for the obsolete 0511630489. Both components share identical electrical and mechanical specifications within the Mini-Lock 51163 series, including connector type, contact configuration, pitch, mounting method, and operating temperature range.

The primary distinction is product lifecycle status: the 0511630489 is classified as obsolete, while the 0511630400 maintains active production status. The 0511630400 additionally provides documented RoHS3 compliance and defined moisture sensitivity level (MSL 1), offering improved regulatory documentation and supply chain availability.

Housing color differs between the two parts (violet versus natural), which is a cosmetic variation without functional impact on electrical or mechanical performance. Selection between these parts should be based on supply availability, regulatory requirements, and any application-specific color specifications.

Frequently Asked Questions (FAQ)

Q: Can the 0511630400 directly replace the 0511630489 in existing designs?

A: Yes. Both parts are functionally equivalent across all electrical and mechanical parameters. They share identical pitch, position count, contact type, termination method, and operating temperature specifications. The housing color difference is cosmetic and does not affect connector performance or compatibility.

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

A: The 0511630489 is classified as obsolete, indicating discontinued production. The 0511630400 is active production, ensuring ongoing availability and supply chain support. For new designs or long-term procurement, the active part is preferred.

Q: Does the housing color affect electrical performance?

A: No. Housing color is a cosmetic attribute determined by the insulation material pigmentation. Both violet and natural housings use identical polybutylene terephthalate (PBT) material with equivalent electrical and thermal properties.

Q: Are there compliance differences between these parts?

A: The 0511630400 provides documented RoHS3 compliance and defined MSL rating (1 - Unlimited), while the 0511630489 lists these as vendor undefined or unspecified. For applications requiring regulatory documentation, the 0511630400 offers superior compliance traceability.

Q: What does MSL 1 (Unlimited) mean for the 0511630400?

A: MSL 1 indicates the component has unlimited shelf life without moisture bake-out requirements. This simplifies storage and handling procedures compared to higher MSL ratings.

Q: Are contacts included with these housings?

A: No. Both the 0511630489 and 0511630400 are housings only. Contacts must be procured separately and crimped into the housing according to Molex specifications.
