Molex 2026542021 Rectangular Connector Housing - Equivalent & Substitute Parts

Part Overview

The Molex 2026542021 is a 2-position receptacle housing for the Pico-EZmate Slim 202654 series rectangular connector system. This component features a 1.20mm pitch, friction lock fastening, and crimp contact termination. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and procurement planning. Substitute parts must maintain identical electrical and mechanical specifications to ensure direct compatibility in existing applications.

Substitute Part Grouping Explanation

Substitute parts for the Molex 2026542021 are identified based on strict equivalence across the following critical parameters:

Connector Type & Contact Configuration: Receptacle housing with female socket contacts
Position Count & Pitch: 2-position arrangement at 0.047" (1.20mm) pitch
Mechanical Interface: Single-row, free hanging in-line mounting with friction lock fastening
Termination Method: Crimp contact termination
Physical Characteristics: Black color housing
Regulatory Compliance: ROHS3 compliance required

The Cvilux USA CI6302S0000 meets all mandatory substitution criteria. Both parts share identical connector topology, position configuration, pitch specification, mounting characteristics, and termination method. Both are ROHS3 compliant and rated for MSL 1 (unlimited moisture sensitivity).

Engineering Selection Recommendations

The Cvilux USA CI6302S0000 is a direct functional equivalent to the obsolete Molex 2026542021. Both parts satisfy identical electrical and mechanical requirements for 2-position, 1.20mm pitch receptacle housing applications with crimp termination and friction lock fastening.

Compliance Status: Both parts maintain ROHS3 compliance and MSL 1 rating, meeting regulatory requirements for equivalent component substitution.

Availability Advantage: The CI6302S0000 is classified as active product status with current inventory availability (3045 pcs), whereas the Molex part is obsolete. This substitution ensures continued procurement capability for new production and field service applications.

Material Consideration: The Cvilux part uses Liquid Crystal Polymer (LCP) insulation versus the Molex polyamide (PA) nylon specification. Both materials are standard for this connector class and maintain equivalent functional performance within the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can the Cvilux USA CI6302S0000 directly replace the Molex 2026542021 in existing assemblies?

A: Yes. Both parts are mechanically and electrically equivalent across all critical parameters: 2-position configuration, 1.20mm pitch, friction lock fastening, crimp termination, and free hanging in-line mounting. Direct substitution is supported.

Q: What is the difference in insulation material between these parts?

A: The Molex part uses polyamide (PA) nylon insulation, while the Cvilux part uses Liquid Crystal Polymer (LCP). Both materials are standard for rectangular connector housings in this pitch class and provide equivalent performance within the operating temperature range of -10°C to 35°C.

Q: Why is the Molex part listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The Cvilux USA CI6302S0000 provides an active, in-stock alternative that maintains full functional equivalence.

Q: Are there any packaging differences between these parts?

A: The Molex part is supplied in bulk packaging, while the Cvilux part is supplied in bag packaging. This difference does not affect component functionality or compatibility.

Q: Do both parts require the same contact specifications?

A: Yes. Both housings are designed for crimp-terminated female socket contacts at 1.20mm pitch. Contact compatibility is determined by pitch and termination method, which are identical across both parts.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.
