Molex 0511030201 Rectangular Connector Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0511030201 is a 2-position rectangular connector receptacle housing with 2.50mm pitch, designed for free-hanging in-line applications. This part operates across the -40°C to 105°C temperature range and features crimp contact termination with latch lock fastening. The product is currently obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

Substitute parts for the Molex 0511030201 are qualified based on the following critical parameters that ensure functional and mechanical compatibility:

Connector Type & Contact Configuration: Receptacle housing with female socket contacts
Position Count & Pitch: 2-position arrangement at 0.098" (2.50mm) pitch
Mounting & Termination: Free-hanging in-line mounting with crimp contact termination
Fastening Mechanism: Latch lock fastening type
Electrical & Environmental Ratings: Operating temperature range and moisture sensitivity classification

The identified substitute parts maintain these core parameters, enabling direct functional replacement in applications originally designed for the 0511030201.

Engineering Selection Recommendations

Molex 0511630200 is the manufacturer-recommended substitute. This part maintains identical electrical and mechanical specifications to the 0511030201 while offering active product status with current manufacturing support. The 0511630200 carries ROHS3 compliance and glow wire compliance certification, providing enhanced regulatory alignment for new designs and ongoing production requirements.

TE Connectivity 2338183-2 serves as a parametric equivalent alternative. This part matches all critical functional parameters including connector type, position count, pitch, mounting configuration, and contact termination. The 2338183-2 is actively manufactured and ROHS3 compliant. The primary distinction is the polyamide insulation material versus the polybutylene terephthalate used in the Molex options, and the absence of specified operating temperature range documentation.

For applications requiring documented temperature range specifications and PBT insulation material consistency, the Molex 0511630200 is the preferred selection. The TE Connectivity 2338183-2 is suitable where polyamide insulation material is acceptable and temperature range specifications are not critical design constraints.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0511630200 directly replace the obsolete 0511030201?

A: Yes. The 0511630200 maintains identical electrical and mechanical parameters including connector type, position count, pitch, mounting type, contact termination, and fastening mechanism. The primary difference is product status (active versus obsolete) and color variation (natural versus black).

Q: What is the functional difference between the Molex and TE Connectivity substitutes?

A: Both parts meet the core functional requirements of 2-position receptacle housings with 2.50mm pitch and crimp latch lock termination. The Molex 0511630200 specifies PBT insulation material and -40°C to 105°C operating temperature range. The TE Connectivity 2338183-2 uses polyamide insulation and does not provide documented operating temperature specifications.

Q: Are there packaging differences between these parts?

A: The Molex 0511030201 is supplied in standard packaging. The Molex 0511630200 and TE Connectivity 2338183-2 are both supplied in bulk packaging, which may affect procurement and handling procedures.

Q: Does the color difference between parts affect compatibility?

A: Color is a cosmetic parameter and does not affect electrical or mechanical compatibility. The black (0511030201), natural (0511630200), and red (2338183-2) housings are functionally interchangeable in applications where color is not a design requirement.

Q: What compliance certifications should I verify for new designs?

A: The Molex 0511630200 carries ROHS3 compliance and glow wire compliance certification. The TE Connectivity 2338183-2 carries ROHS3 compliance. Verify that selected substitutes meet all applicable regulatory requirements for your specific application and market region.
