Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PB-16SM-V are identified based on the following critical parameters that determine functional equivalence:

• Number of Channels: 16 channels (exact match required)
• Style: Mini form factor (exact match required)
• Mounting Type: Standoffs (exact match required)
• Connector Type: Header and/or Screw Terminal Blocks (must support both or equivalent interface)
• Moisture Sensitivity Level: MSL 1 (Unlimited) (exact match required)
• Regulatory Compliance: REACH Unaffected and ECCN EAR99 status (must maintain compliance)

The Grayhill Inc. System 50 series parts 70MRCK16-EC and 70MRCK16-HL meet these core substitution criteria. Both maintain the 16-channel configuration, mini style, standoff mounting, MSL 1 rating, and regulatory compliance required for direct functional replacement.

Parameter Comparison

Engineering Selection Recommendations

70MRCK16-HL is the primary substitute for PB-16SM-V. This part maintains identical connector type configuration (Header, Screw Terminal Blocks) and is currently in active production status with confirmed inventory availability. The part is REACH compliant and carries EAR99 classification, matching the regulatory profile of the original component.

70MRCK16-EC serves as an alternative substitute with the same channel count, style, and mounting configuration. This part features card edge connectors in addition to screw terminal blocks, providing a different interface option. It is also active in production with confirmed inventory and maintains equivalent regulatory compliance.

Both Grayhill substitutes provide active product status, ensuring long-term availability and support compared to the obsolete PB-16SM-V.

Frequently Asked Questions (FAQ)

Q: Can 70MRCK16-HL directly replace PB-16SM-V in existing applications?

A: Yes. Both parts maintain 16 channels, mini style, standoff mounting, identical connector types (Header, Screw Terminal Blocks), and MSL 1 rating. The 70MRCK16-HL is the functionally equivalent substitute.

Q: What is the difference between 70MRCK16-EC and 70MRCK16-HL?

A: The primary difference is connector type. The 70MRCK16-EC includes card edge connectors alongside screw terminal blocks, while 70MRCK16-HL uses header and screw terminal block connectors. Both maintain all other critical parameters for substitution.

Q: Are there RoHS compliance differences between the substitutes?

A: Yes. The 70MRCK16-HL is RoHS non-compliant, while 70MRCK16-EC is RoHS compliant. Selection should account for system-level RoHS requirements.

Q: Why is PB-16SM-V classified as obsolete?

A: The product status reflects that Sensata-Crydom has discontinued this part. Active alternatives from Grayhill Inc. are available to support ongoing procurement needs.

Q: Do the substitute parts have the same packaging?

A: The 70MRCK16-HL is supplied in bulk packaging. Packaging specifications should be verified against procurement requirements.
