PFS713EG Power Factor Correction Controller - Equivalent & Substitute Parts

Part Overview

The PFS713EG is a Power Factor Correction (PFC) controller IC manufactured by Power Integrations, designed for continuous conduction mode (CCM) operation in power management applications. This device operates at switching frequencies between 24kHz and 95kHz and is packaged in a 7-lead eSIP format with through-hole mounting.

The PFS713EG has reached obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this PFC controller architecture.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PFS713EG is determined by the following critical parameters:

Functional Compatibility Criteria:

• Continuous Conduction Mode (CCM) operation requirement
• Power Factor Correction controller functionality
• Through-hole mounting capability
• Operating temperature range: -40°C ~ 125°C minimum
• RoHS and REACH compliance status

Electrical Parameter Constraints:

• Supply voltage range must encompass or exceed the original 10V ~ 12V specification
• Switching frequency range must support the application's operational bandwidth
• eSIP package family compatibility

The PFS7628H and PFS7628H/L are identified as substitute parts within the HiperPFS™ product family, sharing the same functional architecture and compliance certifications while offering enhanced electrical specifications and active product status.

Parameter Comparison

Engineering Selection Recommendations

PFS7628H Selection Criteria:

The PFS7628H is an active product within the HiperPFS™-4 series and represents the primary substitute for the obsolete PFS713EG. This device maintains CCM operation and identical temperature range specifications. The PFS7628H provides an extended supply voltage range (10.2V ~ 15V) that encompasses the original 10V ~ 12V requirement and an expanded switching frequency range (22kHz ~ 123kHz) that covers the original 24kHz ~ 95kHz bandwidth.

The PFS7628H is packaged in a 16-SSIP eSIP-16D format with 13 leads and exposed pad, representing a package upgrade from the 7-lead eSIP-7G configuration. This package change requires PCB layout modification and may necessitate design review for thermal management and signal routing.

Both devices maintain RoHS compliance, MSL 1 rating, and REACH unaffected status, ensuring regulatory continuity.

PFS7628H/L Selection Criteria:

The PFS7628H/L is an active product variant within the HiperPFS™ series. Detailed electrical specifications for this variant are not provided in the available documentation. Selection of this part requires verification of application-specific requirements against the manufacturer's complete datasheet.

Frequently Asked Questions (FAQ)

Q: Can the PFS7628H directly replace the PFS713EG without PCB modifications?

A: No. The PFS7628H uses a 16-SSIP eSIP-16D package with 13 leads, while the PFS713EG uses a 7-SSIP eSIP-7G package with 6 leads. PCB layout redesign is required, including pad configuration, lead spacing, and thermal management provisions.

Q: Are the electrical operating ranges compatible between PFS713EG and PFS7628H?

A: The PFS7628H supply voltage range (10.2V ~ 15V) encompasses the PFS713EG requirement (10V ~ 12V). The PFS7628H switching frequency range (22kHz ~ 123kHz) covers the PFS713EG range (24kHz ~ 95kHz). Both devices operate across the identical temperature range (-40°C ~ 125°C).

Q: What is the significance of the product status change from Obsolete to Active?

A: Active product status indicates ongoing manufacturing, technical support availability, and long-term supply chain reliability. The PFS7628H and PFS7628H/L provide sustained availability compared to the obsolete PFS713EG.

Q: Do all substitute parts maintain the same compliance certifications?

A: Yes. The PFS713EG, PFS7628H, and PFS7628H/L are all RoHS Compliant, MSL 1 (Unlimited), and REACH Unaffected. Regulatory compliance is maintained across all substitute options.

Q: What information is missing for the PFS7628H/L variant?

A: The PFS7628H/L datasheet entry does not include switching frequency range, supply voltage range, operating temperature range, mounting type, or package specifications. Complete technical documentation from Power Integrations is required before design implementation.

Q: How does the package lead count increase affect circuit design?

A: The increase from 6 leads (PFS713EG) to 13 leads (PFS7628H) provides additional functional pins for enhanced control and monitoring capabilities. Circuit schematic redesign and PCB layout modification are mandatory. Thermal pad design and exposed pad connection strategy must be reviewed for the eSIP-16D package.
