Molex 0845110004 Circular Connector Receptacle Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0845110004 is a 31-position circular connector receptacle housing designed for panel mount applications in the Extra Rugged Circular (XRC) series. This component functions as a housing for male pins with bayonet lock fastening and keyed orientation, rated for IP67 ingress protection. The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance, repair, and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the Molex 0845110004 is determined by the following critical parameters:

• Position Count: 31 positions (exact match required)
• Connector Type: Receptacle housing for male pins (exact match required)
• Shell Size: 24-31 insert size (exact match required)
• Contact Configuration: Crimp contact type, size 16 (exact match required)
• Mounting: Panel mount with bayonet lock fastening (exact match required)
• Orientation: Keyed (exact match required)
• Ingress Protection: IP67 minimum (equal or higher acceptable)
• Operating Temperature: -40°C ~ 125°C minimum range (equal or wider acceptable)

The TE Connectivity Deutsch Connectors HDP24-24-31PE meets all critical substitution criteria while offering enhanced environmental protection and active product status.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity Deutsch Connectors HDP24-24-31PE is a direct functional substitute for the obsolete Molex 0845110004. Both components share identical electrical and mechanical specifications for the 31-position circular connector receptacle housing configuration.

The HDP24-24-31PE offers the following advantages:

• Active product status with established supply chain and manufacturing continuity
• Enhanced ingress protection rating (IP68 versus IP67), providing superior dust and water resistance
• Extended lower operating temperature limit (-55°C versus -40°C), expanding operational envelope
• ROHS3 compliance maintained
• Identical contact configuration, mounting interface, and fastening mechanism

Both components are ROHS3 compliant and carry EAR99 ECCN classification. The substitute part is suitable for direct replacement in applications where the Molex 0845110004 was originally specified.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity HDP24-24-31PE be used as a direct replacement for the Molex 0845110004?

A: Yes. Both components share identical specifications for position count (31), connector type (receptacle housing for male pins), shell size (24-31), contact configuration (crimp, size 16), mounting type (panel mount), fastening mechanism (bayonet lock), and orientation (keyed). The substitute meets or exceeds all environmental and temperature specifications.

Q: What are the key differences between these two parts?

A: The primary differences are product status and environmental ratings. The Molex 0845110004 is obsolete, while the TE Connectivity HDP24-24-31PE is actively manufactured. The substitute provides IP68 ingress protection (versus IP67) and operates across a wider temperature range (-55°C to 125°C versus -40°C to 125°C). Shell material differs (polyamide versus polybutylene terephthalate), and the substitute includes a dust cap feature.

Q: Are the contact pins interchangeable between these housings?

A: Both housings accept crimp contacts of size 16. Contact compatibility depends on the specific contact part numbers used in your application. Verify contact specifications separately from housing specifications.

Q: What is the significance of the IP68 rating on the substitute part?

A: IP68 provides complete dust protection and waterproof operation under continuous immersion conditions, exceeding the IP67 specification of the original part. This represents an enhancement for applications requiring higher environmental protection.

Q: Are both parts RoHS compliant?

A: Yes. Both the Molex 0845110004 and TE Connectivity HDP24-24-31PE are ROHS3 compliant, meeting current environmental and hazardous substance restrictions.
