PB-16C4 Equivalent & Substitute Parts

Part Overview

The PB-16C4 is a 16-channel I/O module rack manufactured by Sensata-Crydom, designed for industrial control and signal distribution applications. This product is classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and new installations where legacy component compatibility is required.

The primary reason for identifying substitute parts is the discontinued status of the PB-16C4. Organizations maintaining systems with this component require active alternatives to ensure supply chain continuity and system reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PB-16C4 is determined by the following critical parameters:

• Number of Channels: Must equal 16 channels
• Connector Type: Must support Header and Screw Terminal Blocks
• Mounting Type: Must use Standoffs
• Moisture Sensitivity Level: Must be MSL 1 (Unlimited) or equivalent
• Environmental Compliance: REACH Unaffected status required

The substitute part 70GRCK16-HL meets all mandatory substitution criteria. Both components provide identical channel count, connector configuration, and mounting methodology, enabling direct functional replacement in applications requiring 16-channel I/O module rack functionality.

Parameter Comparison

Engineering Selection Recommendations

The 70GRCK16-HL represents the qualified substitute for the PB-16C4 based on the following factors:

Product Status: The 70GRCK16-HL maintains active product status with current manufacturing support, whereas the PB-16C4 is obsolete. This ensures long-term availability and supply chain reliability.

Compliance Alignment: Both components share identical REACH and ECCN classifications, confirming regulatory equivalence for international distribution and use.

Functional Equivalence: Matching channel count (16), connector configuration (Header, Screw Terminal Blocks), and mounting methodology (Standoffs) establish direct functional compatibility.

Environmental Specifications: Identical MSL ratings (1 - Unlimited) confirm equivalent moisture handling and storage requirements.

Selection of the 70GRCK16-HL eliminates obsolescence risk while maintaining full electrical and mechanical compatibility with existing system designs.

Frequently Asked Questions (FAQ)

Q: Can the 70GRCK16-HL directly replace the PB-16C4 in existing installations?
