Key Parameters

Substitute Part Grouping Explanation

Substitution of the PFS7325H is determined by strict alignment of the following critical parameters:

Package Compatibility: Both the main part and substitute must utilize the 16-SSIP eSIP-16D package format with 13 leads, exposed pad, and formed leads to ensure mechanical and electrical compatibility with existing PCB layouts and through-hole mounting infrastructure.

Electrical Compatibility: The substitute part must operate within the PFC controller functional category and support continuous conduction (CCM) mode operation. Supply voltage ranges must overlap or extend the original specification to ensure proper circuit operation.

Operating Temperature Range: The substitute must maintain the -40°C ~ 150°C junction temperature operating range to support the thermal requirements of the original application.

Regulatory Compliance: Both parts must maintain RoHS compliance and MSL Level 1 classification to satisfy manufacturing and environmental standards.

The PFS7525H qualifies as a direct substitute based on these criteria. It maintains identical package geometry, supports CCM operation, extends the supply voltage range (10.2V ~ 15V), preserves the operating temperature specification, and maintains all regulatory compliance requirements. The PFS7525H is classified as an active product with current manufacturing support.

Engineering Selection Recommendations

Primary Substitute: PFS7525H

The PFS7525H is the manufacturer-recommended substitute for the obsolete PFS7325H. Selection of the PFS7525H is supported by the following engineering factors:

Product Status: The PFS7525H maintains active product status with current manufacturing support from Power Integrations, ensuring long-term supply chain availability and technical support continuity.

Regulatory Compliance: The PFS7525H maintains full RoHS compliance and REACH unaffected status, satisfying all environmental and regulatory requirements equivalent to the original part.

Package Compatibility: Identical 16-SSIP eSIP-16D package format ensures direct mechanical and electrical compatibility with existing PCB designs without layout modifications.

Electrical Specification Alignment: The PFS7525H extends the supply voltage operating range to 10.2V ~ 15V, providing enhanced flexibility for applications while maintaining the original 10.2V ~ 12V specification window. The operating temperature range remains unchanged at -40°C ~ 150°C.

Functional Equivalence: Both parts operate as PFC controllers in continuous conduction mode, maintaining functional equivalence for power factor correction applications.

Frequently Asked Questions (FAQ)

Q: Can the PFS7525H be used as a direct replacement for the PFS7325H without PCB modifications?

A: Yes. The PFS7525H utilizes the identical 16-SSIP eSIP-16D package format with matching lead configuration, pad layout, and through-hole mounting requirements. No PCB layout changes are required for mechanical compatibility.

Q: What is the primary difference between the PFS7325H and PFS7525H?

A: The PFS7525H extends the supply voltage operating range to 10.2V ~ 15V compared to the PFS7325H specification of 10.2V ~ 12V. The PFS7525H also includes switching frequency specification (22kHz ~ 123kHz) and maintains active product status, whereas the PFS7325H is obsolete.

Q: Are there any thermal or operating temperature differences between these parts?

A: No. Both parts maintain identical operating temperature specifications of -40°C ~ 150°C junction temperature, ensuring equivalent thermal performance in the application.

Q: Does the PFS7525H maintain the same regulatory compliance as the PFS7325H?

A: Yes. The PFS7525H maintains RoHS compliance, MSL Level 1 classification, and identical ECCN (EAR99) and HTSUS (8542.39.0001) codes as the original part.

Q: Why is the PFS7325H classified as obsolete?

A: The PFS7325H has been discontinued by Power Integrations. The PFS7525H represents the active product line continuation for PFC controller applications in this package format.

Q: Is the PFS7525H available in the same packaging format (Tube)?

A: The PFS7525H is supplied in tube packaging, which is standard for through-hole component distribution and is compatible with automated assembly processes.

Q: What is the switching frequency range of the PFS7525H?

A: The PFS7525H operates at a switching frequency range of 22kHz ~ 123kHz in continuous conduction mode.
