Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PB-8 are identified based on functional equivalence across the following critical parameters:

• Number of Channels: 8 channels (functional requirement)
• Connector Type: Card Edge and Screw Terminal Blocks (interface compatibility)
• Mounting Type: Standoffs (mechanical compatibility)
• Style: Standard (form factor)

The 70RCK8 manufactured by Grayhill Inc. meets these core functional and mechanical requirements, establishing it as a valid substitute for the obsolete PB-8 in applications requiring 8-channel I/O module rack functionality with identical connector and mounting specifications.

Parameter Comparison

Engineering Selection Recommendations

The 70RCK8 serves as the primary substitute for the obsolete PB-8 based on functional and mechanical parameter alignment. Both components share identical channel count, connector configuration, and mounting methodology, ensuring direct compatibility in rack-mounted I/O applications.

Selection considerations include product status differential: the PB-8 is obsolete while the 70RCK8 remains in active production, supporting long-term availability and supply chain continuity. RoHS compliance status differs between the two parts; the PB-8 is RoHS Compliant while the 70RCK8 is RoHS non-compliant. This distinction requires evaluation against specific regulatory and procurement requirements applicable to the end application.

Both components carry identical ECCN classification (EAR99), indicating equivalent export control treatment.

Frequently Asked Questions (FAQ)

Q: Can the 70RCK8 directly replace the PB-8 in existing installations?

A: The 70RCK8 provides functional and mechanical equivalence to the PB-8 across all critical parameters: 8-channel configuration, card edge and screw terminal block connectors, and standoff mounting. Direct replacement is supported from a technical compatibility standpoint.

Q: What is the significance of the RoHS compliance difference between these parts?

A: The PB-8 is RoHS Compliant while the 70RCK8 is RoHS non-compliant. Applications subject to RoHS regulations or procurement policies requiring RoHS compliance must account for this distinction during component selection.

Q: Why is the PB-8 listed as obsolete?

A: Obsolete status indicates the PB-8 is no longer manufactured by Sensata-Crydom. The 70RCK8, maintained in active production by Grayhill Inc., provides continuity for applications requiring 8-channel I/O module rack functionality.

Q: Are there packaging differences between the PB-8 and 70RCK8?

A: The PB-8 packaging specification is not provided in available documentation. The 70RCK8 is supplied in Bulk packaging. Packaging requirements should be verified against specific procurement and logistics specifications.

Q: Do both parts share the same connector interface?

A: Yes. Both the PB-8 and 70RCK8 utilize Card Edge and Screw Terminal Block connectors, ensuring interface compatibility in applications designed for either component.
