Substitute Part Grouping Explanation

The CPC1967J qualifies as a manufacturer-recommended substitute for the CPC1767J based on the following substitution criteria:

Common Electrical & Mechanical Parameters:

• Identical package format: i4-Pac™-4, Isolated
• Identical supplier device package: i4-PAC™
• Identical moisture sensitivity level: MSL 1 (Unlimited)
• Identical ECCN classification: EAR99
• Compatible voltage load range: 0V to 400V (encompasses the 400VDC rating)
• Identical isolation architecture and pin configuration

Substitution Logic: The CPC1967J maintains the same physical footprint, isolation characteristics, and regulatory compliance profile as the CPC1767J. Both components utilize the i4-Pac™-4 isolated package, ensuring mechanical and electrical compatibility at the board level. The CPC1967J's load voltage range of 0V to 400V directly supports the CPC1767J's 400VDC application requirement.

Engineering Selection Recommendations

Primary Substitute: CPC1967J

The CPC1967J is the manufacturer-recommended substitute for the obsolete CPC1767J. Selection of this component is justified by:

• Active Product Status: The CPC1967J is in active production, ensuring long-term availability and supply chain stability.
• Identical Package Compatibility: Both components use the i4-Pac™-4 isolated package, enabling direct board-level substitution without layout modifications.
• Regulatory Compliance: The CPC1967J achieves ROHS3 compliance and REACH Unaffected status, providing superior environmental and regulatory positioning compared to the REACH Affected CPC1767J.
• Voltage Specification Alignment: The CPC1967J's 0V to 400V load voltage range directly satisfies the CPC1767J's 400VDC application requirement.
• Consistent Isolation Architecture: Both components maintain identical MSL ratings and isolation characteristics, preserving system reliability and thermal performance.

Frequently Asked Questions (FAQ)

Q: Can the CPC1967J be used as a direct replacement for the CPC1767J without PCB modifications?

A: Yes. Both components share the identical i4-Pac™-4 isolated package and i4-PAC™ supplier device package, enabling direct pin-for-pin substitution without PCB layout changes.

Q: What is the primary reason for substituting the CPC1767J?

A: The CPC1767J is obsolete and no longer manufactured. The CPC1967J is the manufacturer-recommended active substitute that maintains equivalent package, isolation, and voltage specifications.

Q: Are there compliance differences between the CPC1767J and CPC1967J?

A: Yes. The CPC1967J is ROHS3 compliant and REACH Unaffected, whereas the CPC1767J is REACH Affected. The CPC1967J provides improved regulatory compliance for new designs and long-term supply chain management.

Q: What is the load current rating of the CPC1967J?

A: The CPC1967J is rated for a maximum load current of 1.35A with a maximum on-state resistance of 850 mOhms.

Q: Are the input voltage specifications identical between the two components?

A: The CPC1767J input voltage specification is not provided in the available documentation. The CPC1967J requires a 1.2VDC input signal for control operation.

Q: What mounting configuration does the CPC1967J use?

A: The CPC1967J is configured for through-hole mounting with PC pin termination, consistent with the i4-Pac™-4 package standard.

Q: Is the CPC1967J suitable for both AC and DC load applications?

A: Yes. The CPC1967J output type supports both AC and DC loads within the 0V to 400V voltage range.
