Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PFS7327H is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Operational mode: Continuous Conduction (CCM)
• Package type: 16-SSIP, 13 Leads, Exposed Pad, Formed Leads (eSIP-16D)
• Mounting type: Through Hole
• Manufacturer series: HiperPFS™
• Supply voltage range: Must encompass or be compatible with 10.2V ~ 13.2V

Compliance Requirements:

• RoHS Compliant status
• REACH Unaffected classification
• Moisture Sensitivity Level 1 (Unlimited)

The PFS7527H qualifies as a direct substitute based on these parameters. Both devices share identical package specifications, mounting methodology, and compliance certifications. The PFS7527H maintains the same eSIP-16D package configuration and through-hole mounting, ensuring mechanical and electrical compatibility with existing PCB designs.

Engineering Selection Recommendations

PFS7527H as Primary Substitute:

The PFS7527H is the qualified substitute for the obsolete PFS7327H. Selection of the PFS7527H is based on the following engineering factors:

Product Status Alignment: The PFS7527H maintains Active product status, ensuring ongoing manufacturer support, availability, and supply chain continuity. The PFS7327H is classified as Obsolete, making the transition to an active part essential for long-term design sustainability.

Compliance and Certification: Both parts maintain identical RoHS Compliant status and REACH Unaffected classification. Both are assigned ECCN EAR99 and HTSUS 8542.39.0001, ensuring regulatory equivalence for export and procurement purposes.

Package and Mounting Compatibility: Identical package specifications (16-SSIP, 13 Leads, Exposed Pad, Formed Leads) and eSIP-16D supplier device package ensure direct PCB compatibility without layout modifications. Through-hole mounting type remains unchanged.

Electrical Parameter Compatibility: The PFS7527H supply voltage range (10.2V ~ 15V) encompasses the PFS7327H requirement (10.2V ~ 13.2V), ensuring functional compatibility in existing applications. The extended operating temperature range (-40°C ~ 150°C versus -40°C ~ 125°C) provides enhanced thermal margin.

Moisture Sensitivity: Both parts maintain MSL 1 (Unlimited) classification, indicating identical handling and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can the PFS7527H be used as a direct replacement for the PFS7327H in existing designs?

A: Yes. The PFS7527H is mechanically and electrically compatible with the PFS7327H. Both devices use identical 16-SSIP eSIP-16D packages with through-hole mounting. No PCB modifications are required for substitution.

Q: What are the key differences between PFS7327H and PFS7527H?

A: The primary differences are product status and electrical specifications. The PFS7327H is obsolete; the PFS7527H is active. The PFS7527H has an 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). The PFS7527H specifies switching frequency capability (22kHz ~ 123kHz), which is not specified for the PFS7327H.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS Compliant status, REACH Unaffected classification, MSL 1 rating, ECCN EAR99 designation, and HTSUS 8542.39.0001 classification.

Q: Does the extended temperature range of the PFS7527H affect compatibility?

A: No. The extended operating temperature range of the PFS7527H (-40°C ~ 150°C) is a superset of the PFS7327H range (-40°C ~ 125°C). This provides additional thermal margin without affecting compatibility in applications operating within the original temperature specification.

Q: Is the extended supply voltage range of the PFS7527H a concern?

A: No. The PFS7527H supply voltage range (10.2V ~ 15V) fully encompasses the PFS7327H requirement (10.2V ~ 13.2V). Applications designed for the PFS7327H will operate within the compatible voltage window of the PFS7527H.

Q: What is the packaging difference between the two parts?

A: There is no packaging difference. Both the PFS7327H and PFS7527H use the 16-SSIP package with 13 leads, exposed pad, and formed leads (eSIP-16D supplier device package). Both are through-hole mounted components.

Q: Are there inventory considerations for the substitution?

A: The PFS7327H is obsolete with limited remaining inventory (840 pcs). The PFS7527H is an active product with higher current availability (1176 pcs). For new designs or ongoing production, the PFS7527H is the recommended selection to ensure supply chain continuity.
