Key Parameters

Substitute Part Grouping Explanation

Substitution of the HR24-9DRA-4S(77) is determined by the following critical parameters:

• Number of Positions: Must be 4 positions to maintain pin count compatibility
• Connector Type: Must be a receptacle with female sockets to match mating interface requirements
• Termination Method: Must use solder cup termination for PCB assembly compatibility
• Category: Must remain within circular connectors classification
• Shell Size: Must accommodate M8-4 or equivalent dimensional specifications

The substitute part 855-004-203R004 from NorComp Inc. meets these criteria as a 4-position circular connector plug with female sockets and solder cup termination, classified within the VULCON™ series. Both parts are designed for industrial and medical applications with equivalent environmental protection ratings.

Parameter Comparison

Engineering Selection Recommendations

The 855-004-203R004 from NorComp Inc. is an active product with ROHS3 compliance and REACH unaffected status, making it suitable for applications requiring regulatory adherence. The substitute part carries IP67 ingress protection rating and operates across -40°C to 85°C, supporting industrial and medical applications. Both parts maintain 4-position solder cup termination architecture, ensuring mechanical and electrical compatibility in equivalent circuit designs.

Selection between these parts should be based on availability, lead time requirements, and specific application environmental conditions. The NorComp substitute provides documented electrical specifications (3A current rating, 60V voltage rating) and material certifications (UL94 V-0 flammability rating) suitable for regulated environments.

Frequently Asked Questions (FAQ)

Q: What makes 855-004-203R004 a valid substitute for HR24-9DRA-4S(77)?

A: Both connectors share the same critical functional parameters: 4-position configuration, female socket termination, and solder cup connection method. These parameters ensure mechanical fit and electrical compatibility in equivalent applications.

Q: Are there differences in connector orientation or mounting between these parts?

A: The NorComp substitute specifies panel mount configuration with bulkhead front-side nut fastening. The HR24 part specifications for mounting type are not provided in the available data. Physical verification of mounting compatibility is necessary before final selection.

Q: What is the significance of the M8-4 shell size specification?

A: M8-4 indicates the shell diameter and position count. This specification ensures proper mating with corresponding plugs and receptacles within the same connector family. Verify that mating components are compatible with this shell size.

Q: Do both parts meet the same environmental protection standards?

A: The NorComp substitute carries IP67 rating (dust tight, waterproof). The HR24 part environmental protection rating is not specified in available documentation. Applications requiring specific ingress protection levels should reference complete technical datasheets.

Q: What packaging considerations apply to these parts?

A: The HR24-9DRA-4S(77) packaging type is not specified. The NorComp substitute is supplied in tray packaging. Verify packaging compatibility with assembly and storage requirements.

Q: Are both parts RoHS compliant?

A: The NorComp substitute is ROHS3 compliant and REACH unaffected. The HR24 part RoHS status is not specified in available data. Regulatory compliance verification is required for applications in restricted markets.
