Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PB-24-C is determined by the following critical parameters:

• Channel Count: 24 channels (exact match required)
• Connector Type: Header and screw terminal blocks (functional equivalence)
• Mounting Type: Standoffs (mechanical compatibility)
• Moisture Sensitivity Level: MSL 1 or better (environmental tolerance)
• REACH and Export Compliance: REACH Unaffected status and EAR99 classification

The 70RCK24-HS from Grayhill Inc. meets all substitution criteria, providing functional equivalence across electrical and mechanical interfaces while maintaining compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

The 70RCK24-HS is a direct functional substitute for the PB-24-C. Both components share identical channel configuration, connector interface, and mounting specifications. The 70RCK24-HS maintains active product status with current manufacturing support, whereas the PB-24-C is obsolete. Both components satisfy REACH compliance requirements and export classification standards. The transition from PB-24-C to 70RCK24-HS does not introduce compliance or regulatory constraints for applications requiring equivalent I/O module rack functionality.

Frequently Asked Questions (FAQ)

Q: What makes the 70RCK24-HS a suitable substitute for the PB-24-C?

A: Both components provide 24-channel I/O module rack functionality with identical connector types (header and screw terminal blocks) and mounting methods (standoffs). Electrical and mechanical interfaces are equivalent, and both maintain MSL 1 moisture sensitivity ratings and REACH compliance.

Q: Are there physical or dimensional differences between these components?

A: The provided specifications confirm matching mounting type (standoffs) and connector configuration. Physical dimensions are not included in the available parameters; mechanical drawings should be consulted for precise installation verification.

Q: Does the active product status of the 70RCK24-HS affect compatibility?

A: No. Active product status indicates current manufacturing availability and technical support. This does not alter electrical or mechanical compatibility with applications designed for the obsolete PB-24-C.

Q: Are there compliance or regulatory differences?

A: Both components are REACH Unaffected and classified as EAR99 for export purposes. No compliance barriers exist for substitution in regulated applications.

Q: Should I verify connector pin assignments before substitution?

A: Connector type specifications are identical (header and screw terminal blocks). Detailed pinout documentation should be reviewed to confirm signal mapping compatibility with existing system designs.
