Key Parameters

Substitute Part Grouping Explanation

Substitution of the PB-8-C is determined by the following critical parameters:

• Number of Channels: Must equal 8 channels
• Connector Type: Must support both header and screw terminal block connections
• Mounting Type: Must use standoff mounting configuration
• Style: Must be standard style
• Moisture Sensitivity Level: Must be MSL 1 or equivalent (unlimited moisture sensitivity)

The 70RCK8-HL from Grayhill Inc. satisfies all substitution criteria based on these parameters. Both modules provide identical channel count, connector interface options, and mounting methodology, enabling direct functional replacement in applications previously specified for the PB-8-C.

Parameter Comparison

Engineering Selection Recommendations

The 70RCK8-HL is the qualified substitute for the PB-8-C based on functional parameter equivalence. The primary distinction is product status: the PB-8-C is obsolete while the 70RCK8-HL remains active in production. Both components maintain identical REACH and ECCN compliance classifications, ensuring regulatory consistency in applications requiring export or environmental compliance documentation.

Selection of the 70RCK8-HL provides the advantage of active manufacturer support and continued availability, addressing the supply constraints inherent to obsolete component replacement. The RoHS non-compliant status of the 70RCK8-HL should be evaluated against application-specific environmental requirements.

Frequently Asked Questions (FAQ)

Q: What makes the 70RCK8-HL a valid substitute for the PB-8-C?

A: Both modules share identical critical parameters: 8-channel configuration, header and screw terminal block connectors, standoff mounting, and MSL 1 moisture sensitivity rating. These parameters define functional equivalence for I/O module rack applications.

Q: Does the change in manufacturer from Sensata-Crydom to Grayhill Inc. affect compatibility?

A: Compatibility is determined by electrical and mechanical parameters, not manufacturer identity. The 70RCK8-HL meets all specified parameter requirements for direct substitution.

Q: What is the significance of the PB-8-C being obsolete?

A: Obsolete status indicates the component is no longer manufactured or supported by Sensata-Crydom. The 70RCK8-HL, being active, provides continued availability and manufacturer technical support.

Q: Are there packaging differences between these modules?

A: The PB-8-C is specified with dash packaging notation, while the 70RCK8-HL is supplied in bulk packaging. Packaging format does not affect functional performance or mechanical compatibility.

Q: How do REACH and ECCN classifications impact substitution?

A: Both components share identical REACH Unaffected and EAR99 ECCN classifications, ensuring regulatory compliance remains consistent when substituting the PB-8-C with the 70RCK8-HL.
