Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PB24 are identified based on the following critical parameters that determine functional equivalence:

• Number of Channels: 24 channels (exact match required)
• Connector Type: Card Edge and Screw Terminal Blocks (both connector types must be present)
• Mounting Type: Standoffs (mechanical compatibility requirement)
• Style: Standard (form factor consistency)

The 70RCK24 manufactured by Grayhill Inc. meets all four core substitution criteria, establishing it as a functionally equivalent alternative to the obsolete PB24.

Parameter Comparison

Engineering Selection Recommendations

The 70RCK24 serves as the primary substitute for the obsolete PB24 based on matching channel count, connector configuration, and mechanical mounting specifications. The 70RCK24 is currently in active production status, ensuring availability for replacement applications.

A critical consideration exists regarding RoHS compliance: the PB24 is RoHS compliant, while the 70RCK24 is RoHS non-compliant. Applications subject to RoHS regulatory requirements must evaluate this compliance difference before substitution. Both parts share the same ECCN classification (EAR99), indicating equivalent export control status.

Frequently Asked Questions (FAQ)

Q: What makes the 70RCK24 a suitable substitute for the PB24?

A: The 70RCK24 matches the PB24 across all critical functional parameters: 24-channel configuration, card edge and screw terminal block connectors, and standoff mounting. These parameters define the mechanical and electrical interface requirements for system integration.

Q: Does the difference in RoHS compliance affect substitution?

A: RoHS compliance status must be evaluated within the context of the application's regulatory environment. The PB24 is RoHS compliant while the 70RCK24 is not. Applications operating under RoHS directives require compliance verification before substitution.

Q: Are there packaging differences between these parts?

A: The PB24 packaging specification is not detailed in available data. The 70RCK24 is supplied in bulk packaging. Packaging format may affect procurement, storage, and handling procedures.

Q: Why is the PB24 classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Sensata-Crydom. The 70RCK24, maintained in active production by Grayhill Inc., provides continuity for applications requiring 24-channel I/O module rack functionality.

Q: Are the connector types identical between both parts?

A: Both the PB24 and 70RCK24 feature card edge and screw terminal block connectors with standoff mounting, ensuring mechanical and electrical interface compatibility.
