Key Parameters

Substitute Part Grouping Explanation

The MA102GQ-Z qualifies as a direct substitute for the MA120GQ-Z based on the following alignment of critical parameters:

Mechanical Compatibility:

• Identical package format: 16-VFQFN Exposed Pad with 16-QFN (3x3) supplier device package
• Matching mounting type: Surface Mount with SMD (SMT) Tab termination
• Both components maintain the same physical footprint and land pattern requirements

Electrical Compatibility:

• Identical functional category: Angle measurement sensor
• Matching technology platform: Hall Effect sensing
• Compatible supply voltage: MA102GQ-Z operates at 3.3V, which falls within the MA120GQ-Z supply range of 3V to 3.6V
• Identical output interface: SPI protocol
• Matching thermal operating range: -40°C to 125°C

Regulatory & Environmental Compliance:

• Both components are ROHS3 Compliant
• Both maintain REACH Unaffected status
• Identical MSL rating: 1 (Unlimited)
• Matching ECCN and HTSUS classifications

Product Lifecycle Status: The MA102GQ-Z is classified as Active, providing long-term availability and supply chain continuity compared to the obsolete MA120GQ-Z.

Parameter Comparison

Engineering Selection Recommendations

The MA102GQ-Z is the manufacturer-recommended substitute for the obsolete MA120GQ-Z. Selection of the MA102GQ-Z is supported by:

Product Lifecycle Continuity: The MA102GQ-Z maintains Active product status, ensuring sustained manufacturing support, documentation availability, and long-term supply chain reliability. The MA120GQ-Z obsolete classification necessitates transition to an alternative component for new designs and ongoing production support.

Regulatory Compliance Alignment: Both components satisfy identical compliance requirements, including ROHS3 Compliant status and REACH Unaffected designation, eliminating regulatory barriers to substitution.

Physical and Electrical Interface Compatibility: Identical package geometry (16-VFQFN Exposed Pad), mounting methodology (Surface Mount), and termination style (SMD Tab) ensure direct PCB compatibility without layout modifications. The 3.3V supply voltage of the MA102GQ-Z operates within the 3V to 3.6V specification window of the MA120GQ-Z, maintaining electrical compatibility.

Thermal Performance Equivalence: Matching operating temperature range (-40°C to 125°C) ensures equivalent thermal performance across all application environments.

Supply Chain Availability: The MA102GQ-Z demonstrates significantly higher inventory levels (15200 Pcs) compared to the MA120GQ-Z (5904 Pcs), providing improved procurement reliability and lead time predictability.

Frequently Asked Questions (FAQ)

Q: Can the MA102GQ-Z be used as a direct replacement for the MA120GQ-Z without PCB modifications?

A: Yes. Both components share identical package specifications (16-VFQFN Exposed Pad), mounting type (Surface Mount), and termination style (SMD Tab). No PCB layout changes are required for substitution.

Q: What is the voltage compatibility between these components?

A: The MA120GQ-Z operates at 3V to 3.6V supply voltage. The MA102GQ-Z operates at 3.3V, which falls within this range. Both components are electrically compatible at the specified supply voltage.

Q: Are there differences in output signal characteristics?

A: The MA120GQ-Z provides SPI output with unspecified output signal characteristics. The MA102GQ-Z provides SPI output with programmable output signal capability. This additional programmability in the MA102GQ-Z does not prevent substitution and may provide enhanced flexibility for system configuration.

Q: Why is the MA120GQ-Z classified as obsolete?

A: The MA120GQ-Z is listed as obsolete by the manufacturer. The MA102GQ-Z is the active equivalent, indicating manufacturer transition to this model for ongoing production and support.

Q: Are the packaging formats compatible for procurement?

A: The MA120GQ-Z packaging format is not specified in available documentation. The MA102GQ-Z is supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly. Confirm packaging requirements with your procurement process.

Q: Do both components meet the same environmental and compliance standards?

A: Yes. Both components are ROHS3 Compliant, REACH Unaffected, and maintain identical Moisture Sensitivity Level (MSL) ratings of 1 (Unlimited). Compliance requirements are equivalent.

Q: What is the operating temperature range for both components?

A: Both the MA120GQ-Z and MA102GQ-Z operate across -40°C to 125°C, providing identical thermal performance specifications.
