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

Part Overview

The PB-24M-C is a 24-channel I/O module rack manufactured by Sensata Technologies, designed for industrial control and signal distribution applications. This component features a mini-style form factor with header and screw terminal block connectors, enabling flexible mounting via standoffs in rack-based systems.

The PB-24M-C carries an obsolete product status. Identifying qualified substitute components ensures system continuity and supports procurement planning for legacy equipment maintenance and new installations requiring compatible I/O module functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PB-24M-C are qualified based on the following critical parameters that determine functional and mechanical compatibility:

• Number of Channels: 24 channels (exact match required)
• Connector Type: Header and Screw Terminal Blocks (exact match required)
• Mounting Type: Standoffs (exact match required)
• Style: Mini form factor (exact match required)
• Moisture Sensitivity Level: MSL 1 (Unlimited) (exact match required)
• REACH Status: REACH Unaffected (compliance maintained)
• ECCN Classification: EAR99 (export control consistency)

The substitute parts 70MRCK24-HL and 70MRCQ24-HL, both manufactured by Grayhill Inc., satisfy all critical electrical and mechanical parameters. Both components are active products with current manufacturing support, providing long-term availability advantages over the obsolete PB-24M-C.

Parameter Comparison

Engineering Selection Recommendations

Both 70MRCK24-HL and 70MRCQ24-HL qualify as direct functional equivalents to the PB-24M-C based on matching electrical and mechanical specifications. The primary advantage of these Grayhill alternatives is their active product status, ensuring ongoing manufacturing support and component availability.

Selection between the two Grayhill options should be based on application-specific requirements and procurement lead times, as both components satisfy identical parameter requirements for the PB-24M-C replacement function.

Frequently Asked Questions (FAQ)

Q: Can 70MRCK24-HL and 70MRCQ24-HL be used interchangeably as replacements for PB-24M-C?

A: Yes. Both components match all critical parameters: 24-channel configuration, mini style, header and screw terminal block connectors, standoff mounting, and MSL 1 rating. Both are active products from Grayhill Inc. with current manufacturing support.

Q: What is the primary reason to transition from PB-24M-C to a substitute part?

A: The PB-24M-C carries obsolete product status. The Grayhill alternatives (70MRCK24-HL and 70MRCQ24-HL) are active products, providing assured long-term availability and manufacturing continuity.

Q: Are there packaging differences between the main part and substitute parts?

A: The PB-24M-C is packaged as standard, while both Grayhill substitutes are supplied in bulk packaging. This does not affect functional or mechanical compatibility.

Q: Do the substitute parts maintain the same compliance certifications?

A: Yes. All three components share identical REACH Status (REACH Unaffected) and ECCN classification (EAR99), ensuring consistent regulatory compliance across substitution.

Q: What are the key parameters that must match for substitution eligibility?

A: Channel count (24), connector type (header and screw terminal blocks), mounting method (standoffs), form factor (mini style), and moisture sensitivity level (MSL 1) must remain constant. All substitute parts satisfy these requirements.
