Key Parameters

Substitute Part Grouping Explanation

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

• Channel Count: 24 channels (exact match required)
• Connector Type: Header and screw terminal blocks (functional equivalence)
• Mounting Configuration: Standoff-based mounting (mechanical compatibility)
• Form Factor: Mini style (physical space constraints)
• Moisture Sensitivity: MSL 1 (Unlimited) or equivalent environmental rating
• Regulatory Compliance: REACH Unaffected status (no hazardous substance restrictions)

The substitute part 70MRCK24-HL meets all critical substitution criteria, maintaining identical channel architecture, connector interface, and mounting methodology while originating from an active product line.

Parameter Comparison

Engineering Selection Recommendations

The 70MRCK24-HL represents a direct functional substitute for the obsolete PB-24SM-V. Both components share identical channel configuration, connector architecture, and mounting methodology. The substitute part maintains equivalent environmental ratings (MSL 1) and regulatory compliance (REACH Unaffected, EAR99 classification).

The primary distinction is product lifecycle status: the PB-24SM-V is obsolete while the 70MRCK24-HL remains in active production through Grayhill Inc. This active status ensures ongoing availability and supply chain continuity. The 70MRCK24-HL is sourced from the System 50 product series, which provides long-term component accessibility for replacement and maintenance applications.

Note: The 70MRCK24-HL carries RoHS non-compliant status, whereas the PB-24SM-V RoHS classification is not specified in available documentation. System designers must evaluate RoHS compliance requirements within their specific application context.

Frequently Asked Questions (FAQ)

Q: What makes the 70MRCK24-HL a valid substitute for the PB-24SM-V?

A: Both components maintain identical channel count (24), connector type (header and screw terminal blocks), mounting configuration (standoffs), and form factor (mini style). Environmental ratings and regulatory classifications are equivalent, ensuring functional and mechanical compatibility.

Q: Are there physical dimension differences between these components?

A: Both parts utilize mini style configuration with standoff mounting. Physical compatibility is maintained across the substitute relationship. Specific dimensional data should be cross-referenced with manufacturer datasheets for installation verification.

Q: What is the significance of the PB-24SM-V being obsolete?

A: Obsolete status indicates the component is no longer manufactured by Sensata-Crydom. The 70MRCK24-HL, maintained in active production status, provides a sourcing solution for replacement and new system designs requiring 24-channel I/O module rack functionality.

Q: Does the RoHS non-compliant status of the 70MRCK24-HL affect substitution eligibility?

A: RoHS compliance requirements are application-specific and determined by end-use regulations and customer specifications. The RoHS status difference between components must be evaluated within the context of the target system's regulatory environment. Both components maintain REACH Unaffected status.

Q: Are connector pin configurations identical between these parts?

A: Both components utilize header and screw terminal block connectors. Detailed pinout verification should be performed using manufacturer technical documentation to ensure signal routing compatibility within the target application.

Q: What inventory considerations apply to these components?

A: The PB-24SM-V has 770 units available as new original stock. The 70MRCK24-HL has 985 units available as new original stock in bulk packaging. Inventory levels should be confirmed with suppliers for current availability.
