Key Parameters

Substitute Part Grouping Explanation

Substitute components for the HMC6352-TR are identified based on the following critical parameters that define functional equivalence within the magnetoresistive sensor category:

Primary Substitution Criteria:

• Manufacturer: Honeywell Aerospace (same manufacturer ensures design compatibility and quality standards)
• Technology: Magnetoresistive (identical sensing technology)
• Axis Configuration: X, Y dual-axis measurement capability
• Sensing Range: ±0.2mT or ±0.6mT (compatible measurement ranges for magnetic field detection)
• Surface Mount Packaging: Ensures PCB integration compatibility

Secondary Compatibility Factors:

• Supply Voltage Range: Overlap or containment within system power budget
• Operating Temperature Range: Minimum coverage of -20°C to 70°C
• Product Status: Active status preferred for long-term availability

The substitute parts listed (HMC1002-TR, HMC1022-TR, HMC1052L-TR) share the core magnetoresistive technology and dual-axis configuration. However, they differ in output interface type (Wheatstone Bridge analog output versus I2C digital output), package form factor, and electrical specifications. These differences require circuit-level design modifications and are not pin-compatible drop-in replacements.

Parameter Comparison

Engineering Selection Recommendations

HMC1002-TR Selection Criteria:

• Active product status ensures current manufacturing and long-term availability
• Identical sensing range (±0.2mT) matches HMC6352-TR specifications
• ROHS3 compliance exceeds original RoHS requirement
• MSL rating of 1 (Unlimited) provides superior moisture handling compared to HMC6352-TR MSL 3
• Wheatstone Bridge output requires analog signal conditioning and ADC conversion instead of I2C interface
• Supply voltage range (5V ~ 12V) requires verification against system power architecture
• Extended operating temperature range (-40°C ~ 85°C) exceeds HMC6352-TR minimum requirement

HMC1022-TR Selection Criteria:

• Active product status with established supply chain
• Wider sensing range (±0.6mT) accommodates higher magnetic field environments
• Broadest supply voltage range (2V ~ 25V) provides maximum design flexibility
• Extended operating temperature range (-40°C ~ 125°C) supports demanding thermal environments
• Smaller package footprint (16-SOIC, 0.154" width) reduces PCB area
• Wheatstone Bridge output requires analog signal path redesign
• RoHS compliance maintained

HMC1052L-TR Selection Criteria:

• Active product status with continuous manufacturing support
• Identical sensing range to HMC1022-TR (±0.6mT)
• Lowest minimum supply voltage (1.8V) enables low-power applications
• Extended operating temperature range (-40°C ~ 125°C) matches HMC1022-TR
• ROHS3 compliance with REACH Unaffected status
• 16-LCC package with exposed pad offers thermal management advantages
• Wheatstone Bridge output requires analog signal conditioning

All substitute parts require circuit redesign due to output interface conversion from I2C digital to Wheatstone Bridge analog. Selection should prioritize product status (all substitutes are Active), compliance certifications, and compatibility with system power supply and signal processing architecture.

Frequently Asked Questions (FAQ)

Q: Can HMC1002-TR, HMC1022-TR, or HMC1052L-TR be used as direct pin-compatible replacements for HMC6352-TR?

A: No. While all components share magnetoresistive technology and dual-axis (X, Y) configuration, they are not pin-compatible. The HMC6352-TR provides I2C digital output, whereas the substitute parts provide Wheatstone Bridge analog output. Package types differ (24-LCC versus 20-SOIC, 16-SOIC, or 16-LCC), requiring PCB redesign and signal conditioning circuit modifications.

Q: What is the primary reason for seeking substitutes for HMC6352-TR?

A: The HMC6352-TR is classified as obsolete, meaning Honeywell Aerospace no longer manufactures this component. All three substitute parts (HMC1002-TR, HMC1022-TR, HMC1052L-TR) maintain Active product status, ensuring continued availability and manufacturing support.

Q: How do the sensing ranges compare between HMC6352-TR and the substitutes?

A: HMC6352-TR and HMC1002-TR both specify ±0.2mT sensing range. HMC1022-TR and HMC1052L-TR specify ±0.6mT, providing three times greater measurement range. Selection depends on the magnetic field strength in the target application.

Q: What are the key differences in supply voltage requirements?

A: HMC6352-TR operates at 2.7V ~ 5.2V. HMC1002-TR requires 5V ~ 12V (narrower, higher range). HMC1022-TR accepts 2V ~ 25V (widest range). HMC1052L-TR accepts 1.8V ~ 20V (lowest minimum voltage). System power architecture must be verified for each candidate.

Q: Which substitute offers the best moisture handling characteristics?

A: HMC1002-TR, HMC1022-TR, and HMC1052L-TR all feature MSL rating of 1 (Unlimited), compared to HMC6352-TR MSL 3 (168 Hours). All substitutes provide superior moisture sensitivity performance, reducing risk in humid storage and operational environments.

Q: Are there temperature range limitations with the substitutes?

A: HMC6352-TR operates -20°C ~ 70°C. HMC1002-TR extends to -40°C ~ 85°C. HMC1022-TR and HMC1052L-TR both extend to -40°C ~ 125°C. All substitutes meet or exceed the original temperature range, with HMC1022-TR and HMC1052L-TR providing the widest thermal operating window.

Q: What is the significance of the Wheatstone Bridge output in the substitute parts?

A: Wheatstone Bridge output is an analog ratiometric interface that requires external signal conditioning, amplification, and analog-to-digital conversion. This differs fundamentally from the HMC6352-TR I2C digital interface, which provides direct digital data over a two-wire serial bus. Circuit redesign is mandatory.

Q: Which substitute part offers the smallest physical footprint?

A: HMC1022-TR in 16-SOIC package (0.154" width, 3.90mm) provides the smallest footprint. HMC1052L-TR in 16-LCC Exposed Pad offers comparable size with thermal management benefits. HMC1002-TR in 20-SOIC (0.295" width, 7.50mm) is larger. PCB layout constraints should guide package selection.

Q: Do all substitutes maintain RoHS compliance?

A: Yes. HMC6352-TR is RoHS Compliant. HMC1002-TR and HMC1052L-TR are ROHS3 Compliant (enhanced standard). HMC1022-TR is RoHS Compliant. All meet regulatory requirements for lead-free manufacturing and hazardous substance restrictions.

Q: What is the bandwidth specification and why does it matter?

A: HMC1002-TR, HMC1022-TR, and HMC1052L-TR all specify 5MHz bandwidth. HMC6352-TR bandwidth is not specified. Bandwidth defines the maximum rate of magnetic field variation the sensor can accurately measure. The 5MHz specification in substitutes supports high-speed magnetic field monitoring applications.
