Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PB-8H are identified based on the following critical parameters that determine functional equivalence:

• Number of Channels: 8 channels (exact match required)
• Connector Type: Header and screw terminal blocks (exact match required)
• Mounting Type: Standoffs (exact match required)
• Style: Standard form factor
• Moisture Sensitivity Level: MSL 1 (Unlimited)

The 70RCK8-HL manufactured by Grayhill Inc. meets all these substitution criteria, providing equivalent electrical and mechanical interface compatibility with the PB-8H.

Engineering Selection Recommendations

The 70RCK8-HL is the qualified substitute for the PB-8H based on matching electrical and mechanical specifications. Key considerations for component selection:

• The 70RCK8-HL maintains active product status with Grayhill Inc., ensuring ongoing availability and supply chain reliability compared to the obsolete PB-8H.
• Both parts comply with REACH regulations and carry EAR99 export classification, supporting equivalent regulatory requirements.
• The 70RCK8-HL is RoHS non-compliant; applications requiring RoHS compliance must evaluate this status against system requirements.
• Identical channel count, connector configuration, and mounting methodology ensure direct functional substitution in existing designs.

Frequently Asked Questions (FAQ)

Q: Can the 70RCK8-HL directly replace the PB-8H in existing applications?

A: Yes. Both parts share identical channel count (8), connector type (header and screw terminal blocks), mounting type (standoffs), and moisture sensitivity rating (MSL 1). These parameters define functional compatibility for I/O module rack applications.

Q: What is the significance of the PB-8H being obsolete?

A: Obsolete status indicates the PB-8H is no longer manufactured by Sensata-Crydom. The 70RCK8-HL, maintained as an active product by Grayhill Inc., provides continued component availability for system repairs and new installations.

Q: Are there compliance differences between these parts?

A: Both parts are REACH Unaffected and classified as EAR99. The 70RCK8-HL is RoHS non-compliant, whereas the PB-8H compliance status is not specified. Applications with RoHS requirements must verify compatibility with the 70RCK8-HL's non-compliant status.

Q: What packaging options are available?

A: The PB-8H is available in standard packaging. The 70RCK8-HL is supplied in bulk packaging. Verify packaging requirements for your procurement process.

Q: Are there inventory considerations for component selection?

A: The PB-8H has 806 pieces in stock as new original inventory. The 70RCK8-HL has 1010 pieces available. Inventory levels may vary; confirm current availability with your supplier.
