Key Parameters

Substitute Part Grouping Explanation

Substitution of the PUSB2X4DH is determined by the following critical parameters:

Package Compatibility: Both the main part and substitute must use the 6-TSOP (SC-74, SOT-457) surface mount package to ensure PCB footprint compatibility without redesign.

Channel Configuration: The 4-channel steering (rail-to-rail) topology must be maintained to preserve circuit protection architecture.

Voltage Ratings: The substitute must operate within the same voltage protection window. The PUSB2X4DH specifies a 6V minimum breakdown voltage and 4.3V typical clamping voltage. Substitutes with comparable voltage standoff and clamping characteristics ensure equivalent transient suppression performance.

Power Line Protection Capability: The substitute must retain power line protection functionality for general-purpose applications.

Compliance & Status: Active product status and ROHS3 compliance ensure long-term availability and regulatory alignment.

The IP4220CZ6,125 meets these substitution criteria through identical package geometry, matching channel count, compatible voltage ratings, and active product status from the same manufacturer.

Engineering Selection Recommendations

The IP4220CZ6,125 is the designated substitute for the obsolete PUSB2X4DH based on the following engineering criteria:

Product Status: The IP4220CZ6,125 maintains active product status, ensuring continued availability and manufacturer support. The PUSB2X4DH obsolescence necessitates transition to an actively produced alternative.

Regulatory Compliance: Both components are ROHS3 compliant and REACH unaffected, maintaining equivalent environmental and regulatory standing.

Package Equivalence: Identical 6-TSOP (SC-74, SOT-457) packaging enables direct PCB footprint compatibility without layout modification.

Functional Topology: Both devices employ 4-channel steering (rail-to-rail) TVS architecture for identical circuit protection application.

Voltage Operating Window: The IP4220CZ6,125 specifies a 5.5V maximum reverse standoff voltage, which aligns with the PUSB2X4DH 6V minimum breakdown voltage, ensuring compatible transient suppression performance within the same voltage protection band.

Moisture Sensitivity: Both components carry MSL 1 (Unlimited) rating, indicating equivalent handling and storage requirements.

Selection of the IP4220CZ6,125 eliminates obsolescence risk while maintaining functional and physical compatibility with existing PUSB2X4DH designs.

Frequently Asked Questions (FAQ)

Q: Can the IP4220CZ6,125 be used as a direct replacement for the PUSB2X4DH without PCB modifications?

A: Yes. Both components use the identical 6-TSOP (SC-74, SOT-457) surface mount package, enabling direct footprint compatibility. No PCB layout changes are required.

Q: What is the primary reason for substituting the PUSB2X4DH?

A: The PUSB2X4DH is classified as obsolete. The IP4220CZ6,125 is an active product from the same manufacturer with equivalent electrical and mechanical specifications, ensuring long-term component availability.

Q: Are the voltage ratings of these two devices compatible?

A: Yes. The PUSB2X4DH specifies 6V minimum breakdown voltage and 4.3V typical clamping voltage. The IP4220CZ6,125 specifies 5.5V maximum reverse standoff voltage. These ratings operate within the same voltage protection window for general-purpose transient suppression applications.

Q: Do both devices support power line protection?

A: Yes. Both the PUSB2X4DH and IP4220CZ6,125 are rated for power line protection and are suitable for general-purpose TVS applications.

Q: What is the difference in capacitance between these devices?

A: The PUSB2X4DH has 0.7pF capacitance at 1MHz, while the IP4220CZ6,125 has 1pF at 1MHz. This 0.3pF difference is negligible for most general-purpose protection circuits and does not affect substitution suitability.

Q: Are the operating temperature ranges identical?

A: Yes. Both devices operate across -40°C to 85°C (TA), ensuring equivalent thermal performance specifications.

Q: What is the moisture sensitivity level for both components?

A: Both devices carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions and identical handling requirements.

Q: Are both components ROHS3 compliant?

A: Yes. Both the PUSB2X4DH and IP4220CZ6,125 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.
