Substitute Part Grouping Explanation

The FAN7711N has been identified as a substitute for the HT8822N based on the following substitution criteria:

• Both devices are manufactured by onsemi within the Power Management (PMIC) category
• Both components share identical REACH compliance status (REACH Unaffected)
• Both components share identical ECCN classification (EAR99)
• Both components share identical HTSUS tariff code (8542.39.0001)
• Both devices are classified as obsolete products, indicating end-of-life status with equivalent market availability constraints
• Package compatibility: Both utilize 8-pin DIP configurations (8-DIP and 8-MDIP)

The substitution is based strictly on regulatory compliance alignment, manufacturer consistency, and package form factor compatibility as provided in the technical specifications.

Parameter Comparison

Engineering Selection Recommendations

Selection between HT8822N and FAN7711N should be based on the following engineering criteria:

• Regulatory Compliance: Both components maintain identical REACH and ECCN compliance status, suitable for equivalent regulatory environments.
• Product Lifecycle Status: Both devices are obsolete. Procurement decisions should account for remaining inventory availability and long-term supply chain implications.
• Package Compatibility: The HT8822N uses 8-MDIP packaging while the FAN7711N uses standard 8-DIP (0.300", 7.62mm) through-hole packaging. Physical board layout and footprint compatibility must be verified before substitution.
• Moisture Sensitivity: The HT8822N specifies MSL 1 (unlimited moisture sensitivity), while the FAN7711N is not applicable for MSL classification. Storage and handling requirements may differ.

Frequently Asked Questions (FAQ)

Q: Can FAN7711N directly replace HT8822N in existing designs?

A: Direct replacement requires verification of package footprint compatibility. While both are 8-pin DIP devices, the HT8822N uses 8-MDIP and the FAN7711N uses standard 8-DIP (0.300", 7.62mm). PCB layout modifications may be necessary.

Q: What is the basis for this substitution relationship?

A: The substitution is based on manufacturer consistency (both onsemi), identical regulatory compliance (REACH Unaffected, EAR99), matching tariff classification (HTSUS 8542.39.0001), and equivalent product lifecycle status (both obsolete).

Q: Are there functional differences between these parts?

A: Functional specifications for the HT8822N were not provided in the technical data. The FAN7711N is specified as a ballast controller operating at 48.7kHz ~ 57.3kHz. Functional compatibility must be independently verified against application requirements.

Q: What should be considered regarding moisture sensitivity?

A: The HT8822N specifies MSL 1 (unlimited), while FAN7711N is not applicable for MSL classification. Storage, handling, and reflow processes may require different environmental controls depending on the selected component.

Q: Are both parts currently available?

A: Both components are classified as obsolete. Inventory availability should be confirmed with authorized distributors before design commitment.
