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

Part Overview

The PB-16 is a 16-channel I/O module rack manufactured by Sensata-Crydom, designed for industrial control and signal distribution applications. This component features card edge and screw terminal block connectors with standoff mounting, supporting up to 16 independent channels in a mini form factor.

The PB-16 has reached obsolete product status. Identifying equivalent substitute parts is necessary to maintain system compatibility and ensure continued availability for replacement, repair, and new installations where this functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PB-16 are identified based on functional equivalence across the following critical parameters:

• Number of Channels: 16 channels (exact match required)
• Connector Type: Card edge and screw terminal blocks (functional compatibility)
• Mounting Type: Standoffs (mechanical compatibility)
• Style: Mini or standard form factor (physical accommodation)
• Moisture Sensitivity Level: MSL 1 (Unlimited) (environmental tolerance)
• REACH and ECCN Compliance: REACH Unaffected, EAR99 classification (regulatory alignment)

Two substitute parts meet these criteria: the Grayhill Inc. 70MRCK16-EC and 70RCK16, both from the System 50 series with active product status.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain functional and mechanical compatibility with the PB-16 across all critical parameters. Selection between the two Grayhill options depends on specific application requirements:

70MRCK16-EC: This substitute maintains the mini form factor of the original PB-16 and carries RoHS Compliant certification. It is suitable for applications requiring environmental compliance and space-constrained installations.

70RCK16: This substitute uses a standard form factor rather than mini, providing a larger physical footprint. It is RoHS non-compliant but remains functionally equivalent across all electrical and connector specifications. This option is suitable for applications where form factor constraints are not critical.

Both parts are active products with current manufacturing status, ensuring long-term availability compared to the obsolete PB-16.

Frequently Asked Questions (FAQ)

Q: Can the 70MRCK16-EC or 70RCK16 directly replace the PB-16 in existing installations?

A: Both parts share identical channel count (16), connector types (card edge and screw terminal blocks), mounting method (standoffs), and environmental ratings (MSL 1). Physical form factor differences exist: the 70MRCK16-EC maintains mini styling, while the 70RCK16 uses standard styling. Mechanical fit must be verified against the specific mounting space available in your application.

Q: What is the difference between the two Grayhill substitutes?

A: The primary differences are form factor (mini vs. standard) and RoHS compliance status. The 70MRCK16-EC is RoHS Compliant, while the 70RCK16 is RoHS non-compliant. Both maintain identical electrical specifications and connector configurations.

Q: Are there any regulatory or compliance considerations when switching from PB-16 to a substitute?

A: All three parts share REACH Unaffected status and EAR99 ECCN classification. If your application requires RoHS compliance, the 70MRCK16-EC is the appropriate choice. The 70RCK16 does not meet RoHS requirements.

Q: How do I verify mechanical compatibility with my existing system?

A: Confirm that the mounting space accommodates the selected form factor (mini for 70MRCK16-EC, standard for 70RCK16) and that the standoff mounting points align with your installation. Connector positioning and terminal block accessibility should be verified against your system layout.

Q: What inventory status should I expect for these substitutes?

A: The 70MRCK16-EC has 868 units in stock, and the 70RCK16 has 1004 units in stock, both available as new original components. The PB-16 is obsolete with 1034 units remaining in inventory.
