PB-24-V I/O Module Rack 24 Channel Equivalent & Substitute Parts

Part Overview

The PB-24-V is a 24-channel I/O module rack manufactured by Sensata Technologies. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and component procurement. The PB-24-V serves as an interface module for industrial control and data acquisition applications requiring multi-channel input/output connectivity with screw terminal block termination.

Key Parameters

Substitute Part Grouping Explanation

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

• Channel Count: 24 channels (exact match required)
• Connector Type: Screw terminal blocks (primary termination method)
• Mounting Type: Standoffs (mechanical interface)
• Moisture Sensitivity Level: MSL 1 (Unlimited)
• Compliance: REACH Unaffected and EAR99 classification

The substitute part 70RCK24 meets the core functional requirements of 24-channel I/O module architecture with screw terminal block connectivity and standoff mounting. Both parts maintain identical MSL ratings and export compliance classifications, establishing electrical and mechanical compatibility within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

The 70RCK24 (Grayhill Inc.) qualifies as a functional substitute for the obsolete PB-24-V based on matching channel count, mounting architecture, and compliance certifications. The primary distinction is connector interface configuration: the PB-24-V incorporates header connectors in addition to screw terminal blocks, while the 70RCK24 uses card edge connectors with screw terminal blocks. Both parts maintain identical MSL ratings and export compliance status.

The 70RCK24 carries active product status, ensuring ongoing availability and supply chain continuity. The RoHS non-compliance designation for the 70RCK24 should be evaluated against system-level environmental and regulatory requirements prior to implementation.

Frequently Asked Questions (FAQ)

Q: What makes the 70RCK24 a valid substitute for the PB-24-V?

A: Both parts share identical channel count (24), mounting type (standoffs), MSL rating (1), and compliance classifications (REACH Unaffected, EAR99). These parameters define functional equivalence for 24-channel I/O module rack applications.

Q: Are there connector compatibility considerations between these parts?

A: The PB-24-V includes header connectors alongside screw terminal blocks, while the 70RCK24 uses card edge connectors with screw terminal blocks. System integration must account for the specific connector interface requirements of the host equipment.

Q: Does the RoHS non-compliance of the 70RCK24 affect substitution eligibility?

A: RoHS compliance is a regulatory and environmental consideration separate from functional substitution parameters. Systems operating under RoHS-restricted environments must evaluate the 70RCK24 against applicable regulatory requirements before deployment.

Q: Why is the PB-24-V classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Sensata Technologies. The 70RCK24 provides an active alternative with equivalent functional specifications.

Q: Are packaging differences relevant to substitution?

A: The PB-24-V is specified with dash packaging, while the 70RCK24 uses bulk packaging. Packaging format does not affect electrical or mechanical compatibility; it reflects procurement and inventory handling methods.
