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

Part Overview

The PB-24SM-BV is a 24-channel I/O module rack manufactured by Sensata-Crydom in the PB series. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for system maintenance, repair, and component sourcing. The module features mini-style construction with header and screw terminal block connectors, designed for rack-mounted I/O applications requiring 24 independent channels.

Key Parameters

Substitute Part Grouping Explanation

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

• Number of Channels: Must equal 24 channels
• Connector Type: Must support Header and Screw Terminal Blocks
• Mounting Type: Must use Standoffs
• Style: Must be Mini configuration
• Moisture Sensitivity Level: Must be MSL 1 (Unlimited) or equivalent

The substitute part 70MRCK24-HL meets all these core electrical and mechanical requirements, enabling direct functional equivalence for I/O module rack applications.

Parameter Comparison

Engineering Selection Recommendations

The 70MRCK24-HL serves as a direct functional equivalent to the PB-24SM-BV for 24-channel I/O module rack applications. Both components share identical channel count, connector configuration, mounting methodology, and environmental specifications. The substitute part maintains REACH compliance and EAR99 export classification consistency.

The primary distinction is product status: the PB-24SM-BV is obsolete while the 70MRCK24-HL is active. For new designs or system replacements, the 70MRCK24-HL is the appropriate selection. The 70MRCK24-HL is RoHS non-compliant; this compliance status should be evaluated against system requirements.

Frequently Asked Questions (FAQ)

Q: Can the 70MRCK24-HL directly replace the PB-24SM-BV in existing systems?

A: Yes. Both components feature 24 channels, identical connector types (Header and Screw Terminal Blocks), standoff mounting, and mini-style construction. Mechanical and electrical compatibility is established through these matching parameters.

Q: What is the significance of the obsolete status of the PB-24SM-BV?

A: Obsolete status indicates the part is no longer manufactured by Sensata-Crydom. The 70MRCK24-HL, classified as active, represents the current available alternative for equivalent functionality.

Q: Are there compliance differences between these parts?

A: Both parts maintain REACH Unaffected status and EAR99 export classification. The 70MRCK24-HL is RoHS non-compliant, whereas the PB-24SM-BV compliance status was not specified. System compliance requirements should be evaluated independently.

Q: Does packaging affect substitution eligibility?

A: Packaging format (bulk versus other configurations) does not affect functional or mechanical compatibility. Selection should be based on procurement and inventory requirements.

Q: Are the MSL ratings equivalent?

A: Yes. Both components are rated MSL 1 (Unlimited), indicating identical moisture sensitivity and storage requirements.
