Key Parameters

Substitute Part Grouping Explanation

Substitution for the PB-24SM-C 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: Standoffs (mechanical compatibility)
• Form Factor: Mini style (physical envelope constraint)
• Moisture Sensitivity: MSL 1 (environmental tolerance)
• Regulatory Compliance: REACH Unaffected and EAR99 classification

The substitute part 70MRCK24-HL from Grayhill Inc. meets all critical substitution criteria, maintaining identical channel count, connector types, mounting method, and environmental specifications.

Parameter Comparison

Engineering Selection Recommendations

The 70MRCK24-HL serves as a direct functional substitute for the obsolete PB-24SM-C. Both parts maintain identical electrical and mechanical specifications across all critical parameters. The 70MRCK24-HL offers the advantage of active product status, ensuring continued availability and supply chain reliability. Both parts comply with REACH regulations and carry EAR99 export classification. The RoHS non-compliant status of the 70MRCK24-HL should be evaluated against system-level compliance requirements if applicable.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts share identical channel count (24), connector types (header and screw terminal blocks), mounting method (standoffs), form factor (Mini), and environmental specifications (MSL 1). Physical and electrical compatibility is maintained.
