PFS710EG Power Factor Correction Controller Equivalent & Substitute Parts

Part Overview

The PFS710EG 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 in the 24kHz to 95kHz switching frequency range and is housed in a 7-lead eSIP package with through-hole mounting.

The PFS710EG has reached obsolete product status. Identifying equivalent and 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 PFS710EG is determined by the following critical parameters:

Functional Compatibility Criteria:

• Operating mode must be Continuous Conduction (CCM)
• Manufacturer must be Power Integrations to ensure design compatibility within the HiperPFS™ architecture
• Supply voltage range must encompass or overlap with the original 10V ~ 12V specification
• Switching frequency range must support the application's operational requirements
• Operating temperature range must meet or exceed -40°C ~ 125°C

Physical and Compliance Criteria:

• Mounting type must be through-hole compatible
• RoHS compliance status must be maintained
• Moisture sensitivity level must be acceptable for storage and handling

The PFS7626H and PFS7626H/L are identified as substitute parts within the Power Integrations HiperPFS™ product family, offering enhanced specifications while maintaining CCM operation and through-hole mounting compatibility.

Parameter Comparison

Engineering Selection Recommendations

PFS7626H Substitution:

The PFS7626H is an active product within the Power Integrations HiperPFS™ family and represents a direct functional substitute for the obsolete PFS710EG. This device maintains CCM operation and through-hole mounting compatibility. The PFS7626H offers an extended supply voltage range (10.2V ~ 15V) and broader switching frequency capability (22kHz ~ 123kHz), providing design flexibility for applications previously constrained by PFS710EG specifications.

The PFS7626H is packaged in a 16-SSIP configuration with 13 leads, which differs from the 7-lead eSIP-7G package of the PFS710EG. PCB layout modifications are required to accommodate the larger package footprint and increased lead count. Both devices maintain identical RoHS compliance and moisture sensitivity ratings.

PFS7626H/L Substitution:

The PFS7626H/L is an active product variant within the HiperPFS™ family. Detailed electrical and package specifications are not provided in the available data. This part should be evaluated only when complete technical documentation is available to confirm compatibility with the original PFS710EG application requirements.

Supply Chain Availability:

Current inventory status indicates PFS7626H availability at 1256 units and PFS7626H/L availability at 817 units, compared to 5285 units of the obsolete PFS710EG. Selection should prioritize active products to ensure long-term supply continuity.

Frequently Asked Questions (FAQ)

Q: Can the PFS7626H directly replace the PFS710EG without PCB modifications?

A: No. The PFS7626H uses a 16-SSIP package with 13 leads, while the PFS710EG uses a 7-SSIP package with 6 leads. PCB layout changes are required to accommodate the different package footprint and lead configuration. Pin-to-pin compatibility must be verified against detailed datasheets before implementation.

Q: What are the key electrical differences between PFS710EG and PFS7626H?

A: The PFS7626H operates with a wider supply voltage range (10.2V ~ 15V versus 10V ~ 12V) and supports a broader switching frequency range (22kHz ~ 123kHz versus 24kHz ~ 95kHz). Both devices maintain identical operating temperature ranges (-40°C ~ 125°C) and CCM operation mode.

Q: Are both substitute parts RoHS compliant?

A: Yes. The PFS7626H and PFS7626H/L are both RoHS compliant with moisture sensitivity level 1 (unlimited), matching the compliance profile of the PFS710EG.

Q: Which substitute part should be selected for new designs?

A: The PFS7626H is recommended for new designs as it is an active product with complete technical specifications available. The PFS7626H/L should only be selected when full electrical and package documentation confirms suitability for the specific application.

Q: Does the PFS7626H support the same frequency range as the PFS710EG?

A: The PFS7626H supports a broader frequency range (22kHz ~ 123kHz) that encompasses the PFS710EG operating range (24kHz ~ 95kHz). Applications designed for the PFS710EG frequency band will operate within the PFS7626H capability envelope.

Q: What is the impact of the larger package size on thermal management?

A: The 16-SSIP package of the PFS7626H provides a larger exposed pad compared to the 7-SSIP package of the PFS710EG. Thermal performance characteristics must be evaluated against specific application power dissipation requirements using detailed thermal data from the manufacturer.
