Key Parameters

Substitute Part Grouping Explanation

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

• Number of Channels: Must be 8 channels
• Mounting Type: Must use standoffs
• Style: Must be standard configuration
• Moisture Sensitivity Level: Must be MSL 1 (Unlimited)
• Connector Type: Must include screw terminal blocks; header connector is acceptable as primary or secondary interface

The substitute parts 70RCK8 and 70RCK8-HL, both manufactured by Grayhill Inc., meet these core electrical and mechanical requirements. Both are active products with current manufacturing status, providing long-term availability compared to the obsolete PB-8-V.

Parameter Comparison

Engineering Selection Recommendations

70RCK8-HL is the primary substitute for PB-8-V applications. This part maintains identical connector type configuration (header and screw terminal blocks), ensuring direct compatibility with existing wiring harnesses and PCB layouts. The 70RCK8-HL is an active product with current manufacturing support, providing superior long-term availability and supply chain stability compared to the obsolete PB-8-V.

70RCK8 serves as an alternative substitute where connector interface differences are acceptable. This part uses a card edge connector in place of the header connector, requiring interface adaptation. The 70RCK8 remains an active product with established supply channels.

Both substitute parts comply with REACH regulations and carry EAR99 export classification, matching the regulatory profile of the original PB-8-V. Selection between 70RCK8-HL and 70RCK8 depends on connector interface requirements within the target application.

Frequently Asked Questions (FAQ)

Q: Can 70RCK8-HL directly replace PB-8-V without modification?

A: Yes. The 70RCK8-HL maintains the same 8-channel configuration, header connector, screw terminal block interface, standoff mounting, and MSL rating as the PB-8-V. No mechanical or electrical adaptation is required.

Q: What is the primary difference between 70RCK8 and 70RCK8-HL?

A: The 70RCK8 uses a card edge connector, while the 70RCK8-HL uses a header connector. Both include screw terminal blocks. The 70RCK8-HL matches the PB-8-V connector configuration more closely.

Q: Are there supply chain advantages to using Grayhill substitutes?

A: Yes. Both 70RCK8 and 70RCK8-HL are active products with current manufacturing status. The PB-8-V is obsolete, making new stock procurement difficult. Grayhill parts offer established distribution channels and ongoing production support.

Q: Do the substitute parts meet the same regulatory requirements as PB-8-V?

A: Yes. Both 70RCK8 and 70RCK8-HL are REACH Unaffected and carry EAR99 classification, matching the regulatory compliance profile of the PB-8-V.

Q: What packaging is available for substitute parts?

A: Both 70RCK8 and 70RCK8-HL are supplied in bulk packaging. Consult with the distributor for specific packaging options and minimum order quantities.
