HV7331K6-G Equivalent & Substitute Parts

Part Overview

The HV7331K6-G is an ultrasound driver pulse generator PMIC manufactured by Microchip Technology, housed in a 64-QFN-EP (9x9) surface mount package with exposed pad. This component is classified as active product status and is designed for pulse generation applications. The device operates within a supply voltage range of 4.85V to 5.15V and is ROHS3 compliant with MSL 3 rating (168 hours moisture sensitivity).

Identifying equivalent and substitute parts is necessary when the primary part number becomes unavailable, when inventory constraints require alternative sourcing, or when design flexibility permits functional equivalents that meet application requirements.

Key Parameters

Substitute Part Grouping Explanation

The HV7321K6-G is identified as a manufacturer-recommended substitute for the HV7331K6-G. Substitution eligibility is determined by the following critical parameters:

• Identical manufacturer (Microchip Technology)
• Identical functional category (Power Management PMIC)
• Identical package type (64-VFQFN Exposed Pad)
• Compatible package dimensions (64-QFN 9x9)
• Identical mounting technology (Surface Mount)
• Overlapping supply voltage range (4.75V ~ 5.25V encompasses the primary part's 4.85V ~ 5.15V range)
• Identical regulatory compliance (ROHS3, REACH Unaffected)
• Identical application classification (Pulse Generator)

Parameter Comparison

Engineering Selection Recommendations

Both the HV7331K6-G and HV7321K6-G maintain active product status with Microchip Technology, ensuring continued manufacturer support and availability. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

The HV7321K6-G substitute demonstrates improved moisture sensitivity characteristics (MSL 1 versus MSL 3), indicating lower moisture absorption risk during storage and handling. The substitute part specifies a supply current of 30µA and operating temperature range of 0°C to 85°C, parameters not provided for the main part. The substitute's supply voltage range (4.75V ~ 5.25V) provides broader tolerance margins compared to the main part's 4.85V ~ 5.15V specification.

Selection between these parts should be based on application-specific requirements regarding moisture sensitivity, supply voltage tolerance margins, and thermal operating conditions.

Frequently Asked Questions (FAQ)

Q: Are the HV7331K6-G and HV7321K6-G pin-compatible?

A: Both components use the 64-VFQFN Exposed Pad package with 9x9mm dimensions. Pin compatibility must be verified against the specific device datasheets, as package type alone does not guarantee identical pinout.

Q: What is the significance of the MSL rating difference?

A: The HV7331K6-G carries MSL 3 (168 hours), while the HV7321K6-G carries MSL 1 (unlimited). MSL rating indicates moisture sensitivity during storage. MSL 1 components have lower moisture absorption risk and do not require time-limited storage conditions.

Q: Can the HV7321K6-G be used in applications designed for the HV7331K6-G?

A: The substitute part meets the primary part's supply voltage range within its broader 4.75V ~ 5.25V specification. Functional compatibility depends on circuit design parameters and application-specific requirements not provided in this reference.

Q: Are both parts available from the same manufacturer?

A: Yes, both the HV7331K6-G and HV7321K6-G are manufactured by Microchip Technology and carry identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Q: What packaging format is used for these components?

A: Both parts are supplied in tray packaging as surface mount components in 64-QFN format with 9x9mm dimensions and exposed pad configuration.
