Molex 0003096021 Rectangular Connector Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0003096021 is a 2-position rectangular connector receptacle housing with a 0.248" (6.30mm) pitch, designed for panel mount and snap-in applications. This component is part of the 1545 series and is actively manufactured. The housing accepts crimp-terminated contacts and features a locking ramp fastening mechanism. Finding equivalent substitute parts may be necessary due to inventory availability, lead time requirements, or specific application constraints while maintaining identical electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitute parts for the Molex 0003096021 are determined by strict equivalence across the following critical parameters:

• Connector Type: Receptacle housing only
• Number of Positions: Exactly 2 positions
• Pitch: 0.248" (6.30mm) contact spacing
• Series: 1545 series compatibility
• Mounting Configuration: Panel mount with snap-in capability
• Contact Termination: Crimp-style termination
• Fastening Mechanism: Locking ramp design
• Insulation Material: Polyamide (PA66) / Nylon 6/6
• Operating Temperature: -40°C to 105°C range
• Regulatory Compliance: ROHS3 compliant, REACH unaffected

The substitute part 0003091027 maintains identical electrical and mechanical specifications across all critical parameters. The only difference is the housing color (Natural versus Black), which does not affect functional compatibility or electrical performance.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0003096021 and 0003091027 are active products with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on:

Inventory Availability: The 0003091027 (Natural color) maintains higher stock levels (12,566 pcs) compared to the 0003096021 (Black color, 2,385 pcs), making it suitable for applications where lead time is a critical factor.

Color Specification: If the application design specifies Black housing for aesthetic or identification purposes, the 0003096021 is the required selection. If color is not a functional requirement, the 0003091027 provides an equivalent alternative.

Regulatory Compliance: Both parts meet identical compliance requirements and are suitable for applications requiring ROHS3 certification.

Frequently Asked Questions (FAQ)

Q: Can the 0003091027 (Natural) be used as a direct replacement for the 0003096021 (Black)?

A: Yes, the 0003091027 is a direct functional equivalent. All electrical and mechanical parameters are identical. The only difference is housing color. Substitution is valid unless the application specifically requires Black housing for design or identification purposes.

Q: Are the contact compatibility and mating characteristics identical between these parts?

A: Yes. Both housings are 1545 series, 2-position, 0.248" (6.30mm) pitch receptacles with crimp termination and locking ramp fastening. They accept identical contact sets and mate with the same plug connectors.

Q: What is the significance of the color difference?

A: Color is a cosmetic parameter only and does not affect electrical performance, mechanical fit, or thermal characteristics. Both Black and Natural housings are manufactured from the same Polyamide (PA66) material with identical operating temperature ranges (-40°C to 105°C).

Q: Are both parts suitable for the same environmental conditions?

A: Yes. Both parts have identical MSL ratings (1 - Unlimited), operating temperature ranges (-40°C to 105°C), and regulatory compliance status. They are suitable for identical environmental applications.

Q: Why would I choose one part over the other if they are functionally equivalent?

A: Selection is based on inventory availability, lead time requirements, and design specifications. The 0003091027 offers higher stock availability. The 0003096021 should be selected if Black housing is a design requirement.
