Key Parameters

Substitute Part Grouping Explanation

The MA302GQ-Z qualifies as a direct substitute for the MA300GQ-Z based on the following critical parameters that determine functional and mechanical compatibility:

Electrical Compatibility Parameters:

• Hall Effect technology foundation
• SPI output interface
• 3V ~ 3.6V supply voltage range
• External magnet actuator requirement
• Operating temperature range: -40°C ~ 125°C

Mechanical Compatibility Parameters:

• Identical package type: 16-VFQFN Exposed Pad
• Identical supplier device package: 16-QFN (3x3)
• Surface mount mounting type
• Same MSL rating: 1 (Unlimited)

Regulatory Compliance Parameters:

• ROHS3 Compliant
• REACH Unaffected
• EAR99 ECCN classification
• HTSUS code: 8542.39.0001

The MA302GQ-Z maintains all critical electrical and mechanical specifications required for direct substitution while offering the advantage of active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The MA302GQ-Z is the designated substitute for the obsolete MA300GQ-Z. Both components share identical electrical specifications, mechanical packaging, and regulatory compliance certifications. The transition from MA300GQ-Z to MA302GQ-Z is supported by:

• Identical pinout and package footprint (16-QFN 3x3)
• Matching supply voltage and operating temperature specifications
• Equivalent SPI interface protocol
• Identical RoHS3 and REACH compliance status
• Active product status with established supply chain availability

The primary distinction is packaging format: MA300GQ-Z is supplied in Tape & Reel format, while MA302GQ-Z is available in Cut Tape and Digi-Reel formats. This difference does not affect electrical or mechanical compatibility and reflects current manufacturing and distribution practices.

Frequently Asked Questions (FAQ)

Q: Can MA302GQ-Z directly replace MA300GQ-Z on existing PCB designs?

A: Yes. The MA302GQ-Z maintains identical pinout, package footprint (16-QFN 3x3), and electrical specifications. No PCB redesign is required.

Q: Are the SPI interface protocols identical between MA300GQ-Z and MA302GQ-Z?

A: Yes. Both components implement the same SPI output interface and operate within the identical 3V ~ 3.6V supply voltage range.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging supplies components on continuous tape in reel format for automated assembly. Cut Tape and Digi-Reel formats provide components in tape segments or alternative reel configurations. All formats contain identical components; the difference is in delivery and handling method.

Q: Do both parts require the same external magnet specifications?

A: Yes. Both MA300GQ-Z and MA302GQ-Z are external magnet sensors with identical actuator requirements. The external magnet is not included with either component.

Q: Are there any temperature or compliance differences between these parts?

A: No. Both components operate across -40°C ~ 125°C and maintain identical ROHS3 and REACH compliance status.

Q: What is the MSL rating and why does it matter?

A: Both components have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These parts can be stored indefinitely without special moisture control measures.
