Molex 0511630486 Rectangular Connector Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0511630486 is a 4-position receptacle housing for the Mini-Lock 51163 connector series, designed for applications requiring 2.50mm pitch rectangular connections. This component features a green polybutylene terephthalate (PBT) insulation body with crimp-type female socket contacts and latch lock fastening. The part is classified as obsolete, necessitating identification of active equivalent alternatives to maintain supply chain continuity and ensure long-term component availability for new designs and legacy system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0511630486 is determined by strict equivalence across the following critical parameters:

• Connector type (receptacle housing)
• Contact type (female socket)
• Position count (4 positions)
• Pitch specification (2.50mm)
• Row configuration (single row)
• Mounting method (free hanging, in-line)
• Termination method (crimp)
• Fastening mechanism (latch lock)
• Insulation material (PBT)
• Operating temperature range (-40°C to 105°C)
• Series designation (Mini-Lock 51163)

The Molex 0511630486 has one manufacturer-recommended substitute: the 0511630400. Both parts share identical electrical and mechanical specifications within the Mini-Lock 51163 series. The primary distinction is product status and color designation, with the substitute part being active and available in natural color versus the obsolete green variant.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0511630400 is the direct substitute for the obsolete 0511630486. Both parts maintain identical electrical and mechanical specifications within the Mini-Lock 51163 connector series, ensuring functional compatibility in applications currently using the 0511630486.

The 0511630400 offers the following advantages for new designs and component replenishment:

• Active product status with established supply chain availability
• ROHS3 compliance certification
• REACH unaffected status
• Defined moisture sensitivity level (MSL 1 - Unlimited)
• Significantly higher inventory availability (58,165 units versus 732 units)

The only functional difference is the housing color (natural versus green). This distinction is cosmetic and does not affect electrical or mechanical performance. Color selection should be based on application-specific requirements or design preferences only.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0511630400 directly replace the 0511630486 in existing applications?

A: Yes. Both parts are identical in all electrical and mechanical specifications. They share the same connector type, contact configuration, pitch, mounting method, termination type, and operating temperature range within the Mini-Lock 51163 series. The only difference is housing color and product status.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: The 0511630486 is classified as obsolete, indicating Molex has discontinued production and support. The 0511630400 is active, meaning it is currently manufactured and supported by Molex with established supply channels. For new designs and long-term component sourcing, the active part is the appropriate choice.

Q: Does the color difference (Green vs. Natural) affect connector performance?

A: No. The color difference is purely cosmetic and does not impact electrical performance, mechanical fit, or thermal characteristics. Selection between green and natural housing should be based on application aesthetics or design specifications only.

Q: Are there any compliance differences between these parts?

A: The 0511630400 provides explicit ROHS3 compliance and REACH unaffected certification. The 0511630486 does not specify these certifications. For applications requiring regulatory compliance documentation, the 0511630400 is the appropriate selection.

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

A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life under standard storage conditions and requires no special moisture control measures during handling or storage. This is the least restrictive MSL classification.

Q: Are the contacts included with these housing parts?

A: No. Both the 0511630486 and 0511630400 are housing components only. Contacts must be sourced separately and crimped into the housing according to Molex specifications.
