Key Parameters

Substitute Part Grouping Explanation

Substitution of the KMZ51,115 is determined by the following critical parameters:

Mechanical Compatibility: Package type (8-SOIC), mounting type (surface mount), and physical dimensions must match to ensure PCB layout compatibility without redesign.

Electrical Compatibility: Technology (magnetoresistive), axis configuration (single), and operating temperature range (-40°C ~ 125°C) establish functional equivalence for magnetic field sensing applications.

Supply Voltage Consideration: The KMZ51,115 operates within 5V ~ 8V. Substitute parts must support this voltage range or be compatible through standard voltage regulation in the application circuit.

Regulatory Compliance: RoHS3 compliance and MSL rating ensure the substitute meets the same environmental and handling standards as the original component.

The HMC1021S-TR meets these substitution criteria through matching package geometry, magnetoresistive technology, single-axis configuration, identical operating temperature range, and equivalent regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The HMC1021S-TR is a direct substitute for the KMZ51,115 based on the following engineering criteria:

Package and Mechanical Fit: Both components use identical 8-SOIC packaging with 0.154" width and 3.90mm dimensions, ensuring drop-in compatibility on existing PCB layouts without modification.

Functional Equivalence: Both sensors employ magnetoresistive technology for single-axis magnetic field detection and share the same operating temperature range (-40°C ~ 125°C), maintaining performance characteristics across the full application temperature envelope.

Regulatory Compliance: The HMC1021S-TR maintains ROHS3 compliance and MSL Level 1 rating, meeting the same environmental and handling requirements as the original component.

Supply Voltage Advantage: The HMC1021S-TR supports a wider supply voltage range (2V ~ 12V) compared to the KMZ51,115 (5V ~ 8V), providing greater design flexibility and compatibility with various power supply configurations.

Product Availability: The HMC1021S-TR is classified as active product status with substantial inventory availability, ensuring long-term procurement reliability compared to the obsolete KMZ51,115.

Frequently Asked Questions (FAQ)

Q: Can the HMC1021S-TR replace the KMZ51,115 without PCB modifications?

A: Yes. Both components use identical 8-SOIC packaging with matching physical dimensions (0.154" width, 3.90mm). Pin-to-pin compatibility and footprint alignment enable direct substitution without PCB redesign.

Q: What is the primary difference between these two sensors?

A: The main difference is output type. The KMZ51,115 provides analog voltage output, while the HMC1021S-TR uses a Wheatstone bridge output configuration. Circuit design must accommodate this output topology difference.

Q: Is the HMC1021S-TR compatible with the 5V ~ 8V supply range of the original design?

A: Yes. The HMC1021S-TR supports 2V ~ 12V supply voltage, which encompasses the original 5V ~ 8V operating range. Existing power supply configurations will function without modification.

Q: Are both components suitable for the same temperature operating range?

A: Yes. Both the KMZ51,115 and HMC1021S-TR operate across -40°C ~ 125°C, ensuring equivalent thermal performance in the application environment.

Q: Do both components meet the same regulatory compliance standards?

A: Yes. Both sensors are ROHS3 compliant with MSL Level 1 rating, meeting identical environmental and handling requirements for manufacturing and deployment.

Q: What is the sensing range difference between these components?

A: The HMC1021S-TR specifies a sensing range of ±0.6mT. The KMZ51,115 sensing range is not provided in the available specifications. Application requirements must be evaluated against the HMC1021S-TR specification.
