Key Parameters

Substitute Part Grouping Explanation

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

• Channel Count: 16 channels (mandatory match)
• Mounting Configuration: Standoffs (mandatory match)
• Style: Standard (mandatory match)
• Moisture Sensitivity Level: MSL 1 (Unlimited) or equivalent
• Connector Interface: Header and/or screw terminal block connectivity

The 70RCK16 manufactured by Grayhill Inc. satisfies these core substitution criteria. While connector type variations exist (Card Edge vs. Header), both designs accommodate screw terminal block integration, enabling functional equivalence in standard I/O rack applications.

Parameter Comparison

Engineering Selection Recommendations

The 70RCK16 is the identified substitute for the obsolete PB-16-C. Selection should be based on the following factors:

Product Status: The 70RCK16 maintains active production status, ensuring long-term availability and supply chain reliability compared to the obsolete PB-16-C.

Regulatory Compliance: Both parts share identical REACH and ECCN classifications (REACH Unaffected, EAR99), confirming equivalent compliance posture for export and environmental regulations.

Connector Compatibility: The primary distinction is connector interface design. The PB-16-C features header connectors, while the 70RCK16 uses card edge connectors. Both support screw terminal block integration, which is the standard interface for I/O rack applications. System integration feasibility depends on existing backplane or interconnect specifications.

Moisture Sensitivity: Both parts carry MSL 1 (Unlimited) ratings, indicating equivalent environmental tolerance for storage and handling.

Frequently Asked Questions (FAQ)

Q: Can the 70RCK16 directly replace the PB-16-C in existing installations?

A: Functional replacement is possible if the system backplane or interconnect accommodates card edge connectors. The 16-channel configuration, standoff mounting, and screw terminal block support ensure electrical and mechanical compatibility. Physical connector interface verification is required before installation.

Q: What is the significance of the connector type difference?

A: The PB-16-C uses header connectors while the 70RCK16 uses card edge connectors. Both designs support screw terminal block termination for signal distribution. The choice between them depends on the existing backplane design and interconnect infrastructure in the target system.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts share identical REACH and ECCN classifications, confirming equivalent regulatory status for industrial applications and international trade.

Q: Why is the PB-16-C classified as obsolete?

A: Obsolescence reflects discontinuation of production by Sensata-Crydom. The 70RCK16 remains in active production, making it the preferred choice for new sourcing and system maintenance.

Q: What is the inventory status for these parts?

A: The PB-16-C has 730 units in stock (new original). The 70RCK16 has 1004 units in stock (new original, bulk packaging), providing greater availability for immediate procurement.
