PFS7325L PFC Controller IC Equivalent & Substitute Parts

Part Overview

The PFS7325L is a Power Factor Correction (PFC) controller IC manufactured by Power Integrations, operating in Continuous Conduction Mode (CCM). This device is designed for power management applications requiring PFC functionality in the HiperPFS™ series. The PFS7325L is classified as obsolete, which necessitates identification of active equivalent parts for new designs and ongoing production requirements. The part is mounted through-hole in a 16-SSIP package with exposed pad and formed leads.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PFS7325L is determined by the following critical parameters that must remain compatible:

Mandatory Compatibility Parameters:

• Functional Mode: Continuous Conduction (CCM) operation
• Package Type: 16-SSIP with eSIP-16G supplier designation
• Mounting Configuration: Through-hole with formed leads and exposed pad
• Manufacturer Series: HiperPFS™ family
• Supply Voltage Range: Minimum overlap with 10.2V ~ 13.2V requirement
• Operating Temperature: Minimum range of -40°C ~ 125°C

The PFS7525L qualifies as a direct substitute because it maintains identical package geometry, mounting type, operational mode, and manufacturer series. The PFS7525L extends the supply voltage range to 10.2V ~ 15V and operating temperature to -40°C ~ 150°C, providing enhanced operational envelope compatibility. Both parts are RoHS compliant with identical MSL ratings and REACH status.

Parameter Comparison

Engineering Selection Recommendations

The PFS7525L is the qualified substitute for the obsolete PFS7325L based on the following engineering criteria:

Product Status Alignment: The PFS7325L is classified as obsolete, making continued sourcing problematic for production and new designs. The PFS7525L maintains active product status with significantly higher inventory availability (3228 pcs vs. 881 pcs), ensuring supply chain continuity.

Regulatory Compliance: Both parts maintain identical RoHS compliance and REACH unaffected status, satisfying regulatory requirements for equivalent substitution. Both parts carry EAR99 ECCN classification and identical HTSUS codes (8542.39.0001).

Package and Mounting Compatibility: Identical 16-SSIP package configuration with eSIP-16G supplier designation ensures direct PCB compatibility without layout modifications. Through-hole mounting with formed leads and exposed pad maintains mechanical and thermal interface equivalence.

Operational Parameter Enhancement: The PFS7525L provides extended supply voltage range (10.2V ~ 15V versus 10.2V ~ 13.2V) and extended operating temperature range (-40°C ~ 150°C versus -40°C ~ 125°C), offering broader application flexibility while maintaining backward compatibility with PFS7325L design specifications.

Frequently Asked Questions (FAQ)

Q: Can PFS7525L be used as a direct replacement for PFS7325L in existing designs?

A: Yes. Both parts share identical package geometry (16-SSIP eSIP-16G), mounting type (through-hole), and operational mode (CCM). The PFS7525L supply voltage range (10.2V ~ 15V) encompasses the PFS7325L requirement (10.2V ~ 13.2V), and the extended temperature range (-40°C ~ 150°C) exceeds the original specification (-40°C ~ 125°C).

Q: What are the key differences between PFS7325L and PFS7525L?

A: The primary differences are product status (obsolete versus active), supply voltage upper limit (13.2V versus 15V), operating temperature upper limit (125°C versus 150°C), and switching frequency specification (not specified versus 22kHz ~ 123kHz). The PFS7525L provides enhanced operational envelope and active manufacturing status.

Q: Are there any package or pinout differences?

A: No. Both parts use identical 16-SSIP package with 13 leads, exposed pad, and formed leads. The eSIP-16G supplier designation is identical for both parts, ensuring PCB footprint and pinout compatibility.

Q: What is the inventory status for these parts?

A: PFS7325L has 881 pcs in stock (obsolete status). PFS7525L has 3228 pcs in stock (active status), providing superior supply chain availability for ongoing production requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both PFS7325L and PFS7525L are RoHS compliant with MSL rating of 1 (Unlimited) and REACH unaffected status, meeting equivalent regulatory requirements.
