Key Parameters

Substitute Part Grouping Explanation

Substitution of the MRMS215L is determined by strict equivalence across 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

The MRMS205A-001 meets all these core substitution criteria. Variations in sensing range parameters (trip and release thresholds) do not preclude substitution when the application tolerates the specified sensing characteristics of the alternative component.

Parameter Comparison

Engineering Selection Recommendations

The MRMS205A-001 is the designated manufacturer substitute for the obsolete MRMS215L. Both components share identical electrical and mechanical specifications across all critical parameters, including supply voltage, current consumption, operating temperature range, and package form factor.

The MRMS205A-001 offers the advantage of active product status, ensuring continued availability and manufacturing support. This component carries ROHS3 compliance certification, meeting current regulatory requirements for electronic component manufacturing and distribution.

The primary technical difference between the two parts lies in sensing range characteristics: the MRMS205A-001 specifies a 3mT trip threshold and 0.2mT release threshold, compared to the MRMS215L's 2.6mT trip and 1.2mT release. Application circuits must accommodate these sensing range variations to ensure proper system operation.

Frequently Asked Questions (FAQ)

Q: Can MRMS205A-001 directly replace MRMS215L in existing designs?

A: Yes, the MRMS205A-001 is electrically and mechanically compatible with the MRMS215L across all core parameters: supply voltage, current consumption, operating temperature, output type, and package configuration. Circuit validation is required to confirm that the different sensing range thresholds are acceptable for the specific application.

Q: What is the primary reason for substitution?

A: The MRMS215L is classified as obsolete. The MRMS205A-001 is the active equivalent component from the same manufacturer, ensuring continued component availability and manufacturing support.

Q: Are there packaging differences between these parts?

A: No. Both components use identical packaging: TO-236-3, SC-59, SOT-23-3 case styles with 3-MM supplier device package designation. Surface mount assembly processes remain unchanged.

Q: How do the sensing range differences affect substitution?

A: The MRMS205A-001 has a higher trip threshold (3mT vs. 2.6mT) and lower release threshold (0.2mT vs. 1.2mT). Applications must be evaluated to confirm these sensing characteristics are compatible with the intended magnetic field environment and switching requirements.

Q: What compliance certifications apply to the substitute part?

A: The MRMS205A-001 is ROHS3 compliant and REACH unaffected. Both components carry MSL 1 (Unlimited) moisture sensitivity rating, indicating no special moisture control requirements during storage or assembly.

Q: Is the supply current identical between both parts?

A: Yes. Both the MRMS215L and MRMS205A-001 specify maximum supply current of 15µA, ensuring equivalent power consumption characteristics in system designs.
