PB-16M-C I/O Module Rack 16 Channel Equivalent & Substitute Parts

Part Overview

The PB-16M-C is a 16-channel I/O module rack manufactured by Sensata-Crydom, designed for industrial control and signal distribution applications. This component features a mini-style form factor with header and screw terminal block connectors, supporting standoff-based mounting configurations. The product is currently classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and component sourcing in legacy equipment applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PB-16M-C are identified based on strict equivalence of the following critical parameters:

• Number of Channels: 16 channels (exact match required)
• Style: Mini form factor (exact match required)
• Connector Type: Header and screw terminal blocks (exact match required)
• Mounting Type: Standoffs (exact match required)
• Moisture Sensitivity Level: MSL 1 (Unlimited) (exact match required)

The substitute parts listed below meet all these criteria and are therefore functionally equivalent for direct replacement in applications requiring 16-channel I/O module rack functionality with identical physical and electrical interface specifications.

Parameter Comparison

Engineering Selection Recommendations

Both 70MRCK16-HL and 70MRCK16-HS manufactured by Grayhill Inc. are direct functional equivalents to the obsolete PB-16M-C. The primary distinction between these substitute options is their active product status, ensuring ongoing availability and supply chain continuity.

The 70MRCK16-HL and 70MRCK16-HS are both classified as active products, providing superior long-term sourcing reliability compared to the obsolete PB-16M-C. Both substitute parts maintain identical electrical and mechanical interface specifications, including 16-channel configuration, mini form factor, header and screw terminal block connectors, standoff mounting, and MSL 1 moisture sensitivity rating.

Both substitute parts carry identical export classification (ECCN: EAR99) and REACH compliance status (REACH Unaffected) as the original component, ensuring regulatory equivalence for applications subject to these compliance frameworks.

Frequently Asked Questions (FAQ)

Q: Can 70MRCK16-HL and 70MRCK16-HS be used interchangeably with PB-16M-C?

A: Yes. Both Grayhill parts meet all critical substitution parameters: 16 channels, mini style, header and screw terminal block connectors, standoff mounting, and MSL 1 rating. They are direct functional equivalents.

Q: What is the primary advantage of using 70MRCK16-HL or 70MRCK16-HS over PB-16M-C?

A: Both substitute parts are classified as active products, ensuring current manufacturing and availability. The PB-16M-C is obsolete and subject to supply discontinuation.

Q: Are there any compliance differences between PB-16M-C and the substitute parts?

A: No. All three parts share identical REACH status (REACH Unaffected) and export classification (ECCN: EAR99).

Q: Do the substitute parts require any modifications to existing mounting or connector interfaces?

A: No. The substitute parts maintain identical mounting type (standoffs) and connector specifications (header and screw terminal blocks), enabling direct physical and electrical replacement.

Q: What is the difference between 70MRCK16-HL and 70MRCK16-HS?

A: Both parts are functionally equivalent with identical electrical and mechanical specifications. The designation suffix indicates variant configurations within the Grayhill System 50 series, but both meet all substitution criteria for PB-16M-C replacement.
