Molex 0009501033 Rectangular Connector Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0009501033 is a 3-position receptacle housing for rectangular connectors with a 0.156" (3.96mm) pitch, designed for free-hanging in-line applications. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing production and maintenance requirements. The housing accommodates female socket contacts with crimp termination and friction lock fastening, operating across a temperature range of -40°C to 105°C.

Substitute Part Grouping Explanation

Substitution of the Molex 0009501033 is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Receptacle housing with female socket contacts
• Position Count & Pitch: 3 positions at 0.156" (3.96mm) pitch
• Mounting & Termination: Free-hanging in-line mounting with crimp contact termination
• Insulation Material: Polyamide-based nylon construction
• Environmental Compliance: RoHS compliance and MSL rating

The TE Connectivity AMP Connectors part number 640250-3 satisfies all substitution criteria. While the fastening mechanism differs (locking ramp versus friction lock), both mechanisms provide equivalent functional retention for crimp-terminated contacts in this connector class. The substitute maintains identical position count, pitch, mounting configuration, and material composition.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 640250-3 is the direct functional equivalent for the obsolete Molex 0009501033. Selection of this substitute is supported by:

• Active Product Status: The substitute maintains active production status, ensuring long-term availability and supply chain continuity.
• Compliance Alignment: Both parts maintain equivalent RoHS and MSL certifications, satisfying regulatory requirements.
• Thermal Performance: The substitute's operating temperature range (-55°C to 105°C) exceeds the original specification, providing enhanced performance margin in low-temperature environments.
• Mechanical Compatibility: Identical pitch, position count, and mounting configuration ensure direct mechanical fit within existing connector assemblies.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 640250-3 directly replace the Molex 0009501033 in existing assemblies?

A: Yes. Both housings accommodate identical 3-position, 0.156" pitch crimp-terminated female socket contacts in a single-row, free-hanging configuration. The housing dimensions and contact interface are functionally equivalent.

Q: What is the difference between friction lock and locking ramp fastening?

A: Both fastening mechanisms provide positive retention of crimp-terminated contacts within the housing. Friction lock uses contact pressure, while locking ramp uses a mechanical ramped surface. Both are suitable for this connector class and do not affect contact compatibility.

Q: Are the insulation materials equivalent?

A: Yes. Both parts use polyamide-based nylon construction. The Molex part specifies PA66 (Nylon 6/6), while the TE Connectivity part specifies PA (Nylon). Both materials provide equivalent electrical insulation and mechanical properties for this application.

Q: Does the substitute require different contact specifications?

A: No. Both housings are designed for identical crimp-terminated female socket contacts. Existing contact inventory is compatible with the substitute housing.

Q: What is the inventory status of the substitute?

A: The TE Connectivity 640250-3 is in active production with 1314 pieces available in bulk packaging, providing reliable supply availability.
