HMC1052 Magnetoresistive Sensor Equivalent & Substitute Parts

Part Overview

The HMC1052 is a magnetoresistive sensor manufactured by Honeywell Aerospace, designed for dual-axis (X, Y) magnetic field detection using Wheatstone Bridge output configuration. This component operates across a wide supply voltage range and is suitable for applications requiring precise magnetic sensing in compact surface-mount packages.

The HMC1052 is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term product availability for existing applications and new designs requiring compatible functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HMC1052 are identified based on strict electrical and mechanical parameter compatibility. The following criteria determine valid substitution:

Core Electrical Parameters:

• Magnetoresistive technology platform
• Dual-axis (X, Y) sensing capability
• Wheatstone Bridge output configuration
• Identical sensing range (±0.6mT)
• Matching supply voltage range (1.8V ~ 20V)
• Equivalent bandwidth (5MHz)
• Identical operating temperature range (-40°C ~ 125°C)

Mechanical & Compliance Parameters:

• Surface-mount packaging
• RoHS compliance status
• MSL rating of 1 or lower
• ECCN classification EAR99

The HMC1052L-TR meets all substitution criteria while offering active product status and improved supply availability.

Parameter Comparison

Engineering Selection Recommendations

HMC1052L-TR as Primary Substitute:

The HMC1052L-TR is the qualified substitute for the obsolete HMC1052. Both components share identical electrical specifications across all critical parameters: magnetoresistive technology, dual-axis sensing, Wheatstone Bridge output, ±0.6mT sensing range, 1.8V ~ 20V supply voltage, 5MHz bandwidth, and -40°C ~ 125°C operating temperature range.

Compliance & Availability Advantages:

The HMC1052L-TR carries active product status from Honeywell Aerospace, ensuring continued manufacturing support and supply chain availability. Both components maintain equivalent RoHS compliance (RoHS3 for HMC1052L-TR represents enhanced compliance over the original RoHS standard). MSL ratings are identical at Level 1, indicating unlimited moisture sensitivity protection.

Package Consideration:

The primary difference is packaging: HMC1052 uses 10-MSOP while HMC1052L-TR uses 16-LCC. Both are surface-mount packages with exposed pad configurations. PCB layout and footprint redesign is required for implementation. The Tape & Reel packaging format of HMC1052L-TR supports automated assembly processes.

Selection Criteria:

For new designs or redesigns of existing applications, HMC1052L-TR is the appropriate selection. For applications where 10-MSOP package geometry is mandatory, alternative magnetoresistive sensors with identical electrical specifications and 10-MSOP packaging should be evaluated from the Honeywell Aerospace product portfolio.

Frequently Asked Questions (FAQ)

Q: Can HMC1052L-TR directly replace HMC1052 without circuit modification?

A: Electrical substitution is valid. All electrical parameters are identical. However, package geometry differs (10-MSOP vs. 16-LCC), requiring PCB footprint and layout redesign. Pin configuration must be verified against application schematics.

Q: What is the difference between 10-MSOP and 16-LCC packages?

A: 10-MSOP (Micro Small Outline Package) is a 10-pin package with 0.118" width. 16-LCC (Leadless Ceramic Chip Carrier) is a 16-pin package with exposed pad. Both are surface-mount technologies suitable for automated assembly. Package selection depends on PCB space constraints and thermal management requirements.

Q: Are there supply chain advantages to using HMC1052L-TR?

A: Yes. HMC1052L-TR maintains active product status with Honeywell Aerospace, ensuring continued manufacturing and distribution. HMC1052 is obsolete, with limited remaining inventory. HMC1052L-TR is available in Tape & Reel format, supporting high-volume automated assembly.

Q: Do both parts meet the same compliance standards?

A: Both components are RoHS compliant and carry MSL Level 1 rating. HMC1052L-TR specifies ROHS3 compliance, representing current regulatory alignment. Both carry EAR99 ECCN classification. REACH status for HMC1052L-TR is listed as REACH Unaffected.

Q: What is the sensing range specification, and does it apply to both parts?

A: Both HMC1052 and HMC1052L-TR specify ±0.6mT sensing range. This represents the magnetic field detection capability across both X and Y axes. Sensing range is identical and does not vary between the two part numbers.

Q: Can HMC1052L-TR be used in applications originally designed for HMC1052?

A: Electrical compatibility is confirmed. Mechanical compatibility requires PCB redesign due to package differences. Thermal performance and signal integrity must be re-evaluated in the new package configuration. Design validation testing is required before production implementation.
