Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0845050003 is determined by strict alignment of the following critical parameters:

• Connector Type & Position Count: Plug housing with 31 positions (non-negotiable for mechanical and electrical compatibility)
• Shell Size Classification: 24-31 insert size (ensures proper mating with corresponding receptacle housings)
• Contact Specifications: Crimp contact type with size 16 (maintains signal integrity and current-carrying capacity)
• Mounting Configuration: Free-hanging (in-line) orientation with keyed design (preserves installation methodology)
• Fastening Mechanism: Bayonet lock coupling nut (ensures secure connection and repeatability)
• Environmental Rating: IP67 minimum ingress protection (maintains dust and moisture sealing requirements)
• Regulatory Compliance: RoHS3 and REACH compliance (ensures material and substance restrictions alignment)

The TE Connectivity Deutsch Connectors HDP26-24-31PE-L017 meets all substitution criteria while offering enhanced specifications in certain areas.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity Deutsch Connectors HDP26-24-31PE-L017 is a direct functional substitute for the obsolete Molex 0845050003. Both components maintain identical mechanical and electrical interface specifications across all critical parameters: 31-position configuration, 24-31 shell size, crimp contact type with size 16, free-hanging in-line mounting, bayonet lock fastening, and keyed orientation.

The substitute part offers enhanced environmental performance (IP68 versus IP67) and extended low-temperature operating range (-55°C versus -40°C), providing additional margin for demanding applications. Both parts maintain full RoHS3 and REACH compliance, ensuring regulatory alignment for current and future procurement requirements.

The TE Connectivity part is currently in active production status with confirmed inventory availability, eliminating supply chain risk associated with the obsolete Molex component.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity HDP26-24-31PE-L017 directly replace the Molex 0845050003 in existing assemblies?

A: Yes. Both components share identical mechanical and electrical interface specifications. The 31-position configuration, shell size 24-31, crimp contact type, bayonet lock fastening, and keyed orientation are functionally equivalent. The substitute part will mate with existing receptacle housings and maintain signal integrity and current-carrying capacity.

Q: What is the significance of the different shell materials (PBT versus PA66)?

A: Both polybutylene terephthalate (PBT) and polyamide 66 (PA66) are glass-filled engineering thermoplastics meeting UL94 flammability standards. The material difference does not affect electrical or mechanical compatibility. PA66 offers slightly different mechanical properties and chemical resistance characteristics, but both materials are suitable for the specified operating temperature range and environmental conditions.

Q: Why does the substitute part have IP68 rating instead of IP67?

A: The TE Connectivity part exceeds the original specification. IP68 provides complete dust protection and waterproofing under continuous immersion, whereas IP67 provides dust protection and waterproofing under temporary immersion. This represents an enhancement that maintains backward compatibility with IP67 requirements.

Q: Are there packaging differences between these components?

A: The Molex part is listed with unspecified packaging, while the TE Connectivity substitute is supplied in bulk packaging. Confirm packaging requirements with your procurement process to ensure compatibility with your assembly workflow.

Q: Do both parts require the same contact insertion specifications?

A: Yes. Both components use crimp contact type with size 16 specifications. Contact insertion, crimping procedures, and tooling requirements remain identical between the two parts.
