Key Parameters

Substitute Part Grouping Explanation

Substitution of the MRMS215M is determined by strict alignment of the following critical parameters:

• Function: Unipolar Switch operation
• Technology: Magnetoresistive sensing
• Polarization: South Pole detection
• Output Type: Push-Pull configuration
• Voltage Supply Range: 3V ~ 5.5V compatibility
• Operating Temperature Range: -40°C ~ 85°C
• Mounting Type: Surface Mount
• Package / Case: TO-236-3, SC-59, SOT-23-3 form factor
• Supplier Device Package: 3-MM dimensions

The MRMS205A-001 meets all these core substitution criteria. While sensing range specifications differ between the main part and substitute, both components maintain identical electrical interfaces, supply requirements, output characteristics, and physical packaging, enabling direct functional replacement in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The MRMS205A-001 is the manufacturer-recommended substitute for the obsolete MRMS215M. Both components share identical electrical specifications, supply voltage requirements, output characteristics, and physical packaging. The substitute part maintains active product status with ROHS3 compliance certification, ensuring long-term availability and regulatory alignment for new designs and legacy system support.

The primary technical distinction between these components is the sensing range specification. The MRMS205A-001 operates with a 3mT trip threshold and 0.2mT release threshold, compared to the MRMS215M's 2.1mT trip and 0.9mT release specifications. This difference must be evaluated against specific application magnetic field requirements to ensure functional compatibility within the target system.

Frequently Asked Questions (FAQ)

Q: Can the MRMS205A-001 directly replace the MRMS215M in existing designs?

A: The MRMS205A-001 provides electrical and mechanical compatibility with identical supply voltage ranges, output types, operating temperature ranges, and physical packaging. However, the different sensing range thresholds require application-level verification to confirm functional equivalence for your specific magnetic field environment.

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

A: Both components are magnetoresistive unipolar switch sensors with push-pull output and identical electrical interfaces. The primary difference is the sensing range: MRMS215M operates at 2.1mT trip / 0.9mT release, while MRMS205A-001 operates at 3mT trip / 0.2mT release. Both maintain the same 3V to 5.5V supply voltage, 15µA maximum supply current, and -40°C to 85°C operating temperature range.

Q: Why is the MRMS215M classified as obsolete?

A: The MRMS215M has been discontinued by the manufacturer. The MRMS205A-001 represents the active product line continuation within the MRMS2 base product family, offering equivalent functionality with modern compliance certifications.

Q: Are there packaging differences between these parts?

A: Both components use identical packaging: TO-236-3, SC-59, SOT-23-3 case styles with 3-MM supplier device package dimensions. The MRMS205A-001 is supplied in Tape & Reel (TR) format, while the MRMS215M packaging format is not specified.

Q: What compliance certifications apply to the substitute part?

A: The MRMS205A-001 is ROHS3 compliant and REACH unaffected. Both components carry EAR99 ECCN classification and 8536.41.0030 HTSUS code with Moisture Sensitivity Level 1 (Unlimited).
