Substitute Part Grouping Explanation

The Molex 1120955040 has one manufacturer-recommended substitute: 1120955137. This substitution is valid based on the following alignment of critical parameters:

• Base Product Series: Both parts share the same base product number (112095), indicating they belong to the Brad HarshIO connector family
• Environmental Protection: Both maintain IP67 rating, ensuring equivalent dust-tight and waterproof performance
• Form Factor: Both use 60MM dimensions, ensuring mechanical compatibility with existing mounting infrastructure
• Connector Configuration: Both feature 8-position, 4-contact architecture
• Channel Architecture: Both support 16-channel input capability
• Material Composition: Both utilize Polybutylene Terephthalate (PBT) for shell construction
• Shell Size: Both specify M12 insert size

The primary distinction is that the substitute part (1120955137) is in Active production status with current inventory availability, whereas the original part is Obsolete.

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Ongoing Production: Specify Molex 1120955137 as the primary component. This part is in Active production status, ensuring long-term supply chain reliability and compliance with current manufacturing standards (ECCN: EAR99, HTSUS: 8537.10.9170).

For Legacy System Maintenance: The Molex 1120955040 remains functionally equivalent to 1120955137 for repair and replacement applications where existing inventory is available. However, transition to the Active substitute part is recommended to avoid future supply constraints.

Compliance Considerations: Both parts are classified under HTSUS code 8537.10.9170 (electrical apparatus for making/breaking circuits) and carry appropriate export classifications. The substitute part carries standard EAR99 classification suitable for general commercial distribution.

Frequently Asked Questions (FAQ)

Q: Can Molex 1120955137 directly replace Molex 1120955040 in existing installations?

A: Yes. Both parts share identical environmental protection (IP67), form factor (60MM), connector configuration (8P4), and channel architecture (16-channel input). The substitute part is mechanically and functionally compatible with systems designed for the original part.

Q: What is the primary reason for substitution?

A: The original part (1120955040) is Obsolete and no longer manufactured. The substitute (1120955137) is in Active production status, providing assured supply availability and compliance with current manufacturing standards.

Q: Are there differences in output logic between these parts?

A: The original part specifies PNP output logic. The substitute part description lists "16I" (16 Input) without explicit PNP designation in the provided data. Verify output logic compatibility with your application requirements before final selection.

Q: What packaging options are available?

A: The original part uses standard packaging (indicated as "-"). The substitute part is supplied in Bulk packaging, suitable for production environments and OEM integration.

Q: Are both parts suitable for IP67-rated applications?

A: Yes. Both parts carry IP67 environmental rating, indicating dust-tight and waterproof performance suitable for harsh industrial environments.

Q: What is the material composition of the connector shell?

A: The substitute part (1120955137) uses Polybutylene Terephthalate (PBT) for shell construction, providing chemical resistance and mechanical durability. Material specification for the original part is not provided in available documentation.
