Key Parameters

Substitute Part Grouping Explanation

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

• Channel Count: 16 channels (exact match required)
• Connector Type: Card edge and screw terminal block interfaces
• Mounting Configuration: Standoff-based mounting system
• Form Factor: Mini style packaging
• Environmental Rating: MSL 1 (Unlimited) moisture sensitivity

The 70MRCK16-HL from Grayhill Inc. qualifies as a functional substitute based on matching channel count, mounting type, style classification, and environmental rating. Both components support 16-channel I/O functionality with standoff mounting in a mini form factor and identical MSL ratings.

Parameter Comparison

Engineering Selection Recommendations

The 70MRCK16-HL is available as an active product with current manufacturing support, whereas the PB-16SM is obsolete. Both components maintain identical MSL ratings and REACH compliance status, supporting equivalent environmental handling requirements. The primary design consideration is connector interface compatibility: the PB-16SM uses card edge connectors while the 70MRCK16-HL uses header connectors. System integration must account for this connector type difference during mechanical and electrical interface design.

Frequently Asked Questions (FAQ)

Q: What makes the 70MRCK16-HL a valid substitute for the PB-16SM?

A: Both components provide 16-channel I/O functionality with standoff mounting in mini form factor packaging. They share identical MSL ratings (1 - Unlimited) and REACH compliance status, meeting the core environmental and regulatory requirements for this product category.

Q: Are there connector compatibility concerns between these parts?

A: Yes. The PB-16SM uses card edge connectors while the 70MRCK16-HL uses header connectors. System designs must accommodate this interface difference during PCB layout and mechanical assembly planning.

Q: Does the active product status of the 70MRCK16-HL affect substitution validity?

A: No. Active product status indicates current manufacturing availability and supply chain support, which is advantageous for new designs and long-term system maintenance. Substitution validity is determined by functional and environmental parameter matching, not product lifecycle status.

Q: Are there differences in regulatory compliance between these parts?

A: Both components share identical REACH status (REACH Unaffected) and ECCN classification (EAR99). No additional compliance considerations apply to substitution between these parts.
