Key Parameters

Substitute Part Grouping Explanation

Substitution of the MRMS215H is determined by strict alignment of the following critical parameters:

• Unipolar switch function with south pole polarization
• Magnetoresistive sensing technology
• Push-pull output configuration
• Surface mount package in TO-236-3 / SC-59 / SOT-23-3 form factor
• Supply voltage range of 3V to 5.5V
• Maximum supply current of 15µA
• Operating temperature range of -40°C to 85°C
• MSL rating of 1 (Unlimited)

The MRMS205A-001 qualifies as a direct substitute based on these parameters. While sensing range specifications differ between the main part and substitute, both components maintain identical electrical interfaces, mechanical packaging, and environmental operating conditions required for functional equivalence in circuit applications.

Engineering Selection Recommendations

The MRMS205A-001 is the qualified substitute for the obsolete MRMS215H. Selection of this substitute is supported by:

• Active product status ensuring continued availability and manufacturing support
• ROHS3 compliance certification for regulatory alignment with current environmental standards
• Identical electrical and mechanical specifications across all critical interface parameters
• Equivalent MSL rating and environmental operating conditions
• Same base product family (MRMS2) confirming design lineage and compatibility

Frequently Asked Questions (FAQ)

Q: Can the MRMS205A-001 directly replace the MRMS215H in existing designs?

A: Yes. Both components share identical supply voltage ranges, current specifications, output configurations, operating temperature ranges, and physical packaging. The components are pin-compatible and functionally equivalent for circuit-level integration.

Q: What is the difference in sensing range between these parts?

A: The MRMS215H specifies a trip threshold of 1.6mT with 0.6mT release, while the MRMS205A-001 specifies 3mT trip with 0.2mT release. Application designs must account for these magnetic field sensitivity differences during component selection.

Q: Is the MRMS205A-001 available in the same package format?

A: Yes. Both parts use the TO-236-3 / SC-59 / SOT-23-3 surface mount package. The MRMS205A-001 is supplied in Tape & Reel (TR) packaging format, standard for production volume applications.

Q: What compliance certifications apply to the substitute part?

A: The MRMS205A-001 carries ROHS3 compliance certification and maintains REACH Unaffected status, consistent with current regulatory requirements for electronic components.

Q: Are there any thermal or environmental limitations when substituting this component?

A: No. Both parts operate across the identical temperature range of -40°C to 85°C and maintain MSL 1 (Unlimited) moisture sensitivity ratings, ensuring equivalent performance in all specified environmental conditions.
