MRMS211L Equivalent & Substitute Parts

Part Overview

The MRMS211L is a magnetoresistive unipolar switch sensor manufactured by Murata Electronics, designed for digital switching applications with push-pull output configuration. This component operates across a supply voltage range of 1.6V to 4.6V with a maximum supply current of 12µA and features temperature compensation for stable operation across -40°C to 85°C. The product is currently obsolete, making identification of compatible substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MRMS211L is determined by compatibility across the following critical parameters:

• Package Compatibility: Both main and substitute parts must use the same physical package (TO-236-3, SC-59, SOT-23-3) to ensure PCB footprint alignment
• Voltage Supply Range: Substitute must operate within or encompass the 1.6V ~ 4.6V supply voltage specification
• Current Consumption: Supply current must not exceed the 12µA maximum specification
• Operating Temperature Range: Substitute must support the full -40°C ~ 85°C operating window
• Mounting Type: Surface mount configuration must be maintained
• Technology Platform: Magnetoresistive technology ensures consistent sensor behavior and response characteristics
• Base Product Series: Both parts belong to the MRMS2 base product family, confirming design lineage and compatibility

The MRMS201A-001 qualifies as a substitute based on these parameters. While it functions as a latch switch rather than a unipolar switch, and detects both north and south pole magnetization, it maintains electrical and mechanical compatibility across all critical substitution criteria.

Engineering Selection Recommendations

The MRMS201A-001 is the manufacturer-recommended substitute for the obsolete MRMS211L. Selection of this substitute is supported by the following factors:

• Product Status: The MRMS201A-001 maintains active product status with current manufacturing and distribution, ensuring long-term availability and supply chain continuity
• Regulatory Compliance: Both components share identical REACH and ECCN classifications, confirming equivalent regulatory standing
• Electrical Compatibility: Matching supply voltage range (1.6V ~ 4.6V), maximum supply current (12µA), and operating temperature range (-40°C ~ 85°C) ensure direct functional replacement in existing circuit designs
• Physical Compatibility: Identical package specifications (TO-236-3, SC-59, SOT-23-3) and surface mount configuration enable direct PCB placement without layout modifications
• Supply Availability: The MRMS201A-001 is available in high inventory quantities (16,462 pcs) in tape and reel packaging, supporting both prototype and production-volume requirements

Frequently Asked Questions (FAQ)

Q: Can the MRMS201A-001 directly replace the MRMS211L in existing designs?

A: Yes. Both components share identical electrical specifications (supply voltage, current consumption, operating temperature) and physical packaging (TO-236-3, SC-59, SOT-23-3). The primary functional difference is that the MRMS211L operates as a unipolar switch detecting south pole magnetization, while the MRMS201A-001 functions as a latch switch detecting both north and south pole magnetization. Circuit designs must account for this functional difference in application logic.

Q: What are the key differences between these two parts?

A: The MRMS211L is a unipolar switch with push-pull output, while the MRMS201A-001 is a latch switch with digital output. The MRMS211L detects only south pole magnetization with a 2.6mT trip threshold and 1.2mT release threshold. The MRMS201A-001 detects both north and south pole magnetization with a 2.5mT trip threshold and 0.5mT release threshold. Both maintain identical electrical and mechanical compatibility.

Q: Are there packaging differences between these parts?

A: Both components use the same physical package (TO-236-3, SC-59, SOT-23-3). The MRMS211L is supplied in standard packaging, while the MRMS201A-001 is available in tape and reel (TR) format, which is standard for production quantities.

Q: What compliance certifications apply to both parts?

A: Both the MRMS211L and MRMS201A-001 are REACH Unaffected, classified under ECCN EAR99, and share the same HTSUS code (8536.41.0030). Both have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions.

Q: Why is the MRMS211L obsolete?

A: The MRMS211L has been discontinued by Murata Electronics. The MRMS201A-001 is the active replacement product within the MRMS2 product family, offering equivalent electrical and mechanical specifications with enhanced functionality through latch-mode operation.
