Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0334720809 is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Receptacle housing with female socket contacts
• Electrical Interface: 8-position arrangement with 0.138" (4.60mm) pitch and 2-row configuration
• Mechanical Interface: Free-hanging in-line mounting with crimp termination and latch holder fastening
• Functional Features: Connector Position Assurance (CPA) and sealed design
• Series Compatibility: MX150 33472 series designation
• Regulatory Compliance: ROHS3 compliance and MSL 1 rating

The substitute part Molex 0334724807 maintains identical electrical and mechanical specifications across all these parameters, with the primary distinction being housing color (gray versus green) and active product status, making it a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0334724807 is the direct functional equivalent for the obsolete Molex 0334720809. Both parts maintain identical electrical and mechanical specifications within the MX150 33472 series, ensuring pin-for-pin and form-factor compatibility.

Selection of the 0334724807 is supported by:

• Active Product Status: The substitute maintains active manufacturing status, ensuring reliable long-term supply availability and continued manufacturer support
• Regulatory Compliance: Both parts maintain ROHS3 compliance and MSL 1 rating, meeting current environmental and reliability standards
• Functional Equivalence: All critical parameters—connector type, contact configuration, pitch, mounting interface, and fastening mechanism—are identical
• Housing Color Distinction: The gray housing of the 0334724807 differs from the green housing of the 0334720809; this distinction is cosmetic and does not affect electrical or mechanical function

For applications where housing color is a design or identification requirement, color compatibility must be evaluated independently. In all other applications, the 0334724807 provides direct substitution without functional compromise.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0334724807 be used as a direct replacement for the 0334720809 in existing assemblies?

A: Yes. The 0334724807 maintains identical electrical and mechanical specifications, including connector type, contact configuration, pitch, mounting interface, and fastening mechanism. Direct substitution is functionally compatible.

Q: What is the difference between the green housing of the 0334720809 and the gray housing of the 0334724807?

A: Housing color is a cosmetic distinction with no impact on electrical or mechanical performance. Both housings are constructed from polyamide (PA) nylon with glass filling and syndiotatic polystyrene (SPS), maintaining identical material properties and operating characteristics across the -40°C to 150°C temperature range.

Q: Why is the 0334720809 classified as obsolete?

A: Obsolescence reflects manufacturer discontinuation of production. The 0334724807 remains in active production within the same MX150 33472 series, providing continued availability and manufacturer support.

Q: Are the contact termination methods identical between these parts?

A: Yes. Both parts use crimp termination with latch holder fastening, ensuring compatibility with existing contact tooling and assembly processes.

Q: Do both parts support Connector Position Assurance (CPA)?

A: Yes. Both the 0334720809 and 0334724807 incorporate CPA functionality and sealed design, maintaining identical protective features.

Q: What is the packaging difference between these parts?

A: The 0334720809 is listed with unspecified packaging, while the 0334724807 is supplied in bulk packaging. Packaging format does not affect component function or compatibility.
