Substitute Part Grouping Explanation

Substitute parts for the MIC803-30D2VC3-TR are qualified based on the following electrical and mechanical parameters:

• Functional Type: Simple Reset/Power-On Reset supervisor with single-channel voltage monitoring
• Output Configuration: Open Drain or Open Collector output
• Reset Logic: Active Low
• Package Compatibility: SC-70, SOT-323 surface mount package
• Voltage Threshold Range: Threshold values within acceptable operating margins for 3V monitoring applications
• Reset Timeout: Minimum timeout specifications suitable for power-on reset sequencing
• Operating Temperature: -40°C ~ 125°C range
• Compliance: ROHS3 Compliant, REACH Unaffected, MSL 1

The substitute parts MAX803SEXR/V+T and MAX803TEXR/V+T meet these criteria and are manufactured by Analog Devices Inc./Maxim Integrated.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and ROHS3 compliance. The MIC803-30D2VC3-TR operates with a 20ms minimum reset timeout, while both MAX803 variants specify 140ms minimum reset timeout. Voltage threshold values are closely matched: MIC803-30D2VC3-TR at 3V, MAX803SEXR/V+T at 2.93V, and MAX803TEXR/V+T at 3.08V.

The MAX803SEXR/V+T and MAX803TEXR/V+T are qualified to AEC-Q100 automotive standards, whereas the MIC803-30D2VC3-TR does not specify automotive qualification. Both substitute parts are manufactured by Analog Devices Inc./Maxim Integrated and are available in higher inventory quantities (7781 Pcs and 847 Pcs respectively) compared to the primary part (2100 Pcs).

Frequently Asked Questions (FAQ)

Q: Can MAX803SEXR/V+T and MAX803TEXR/V+T be used interchangeably with MIC803-30D2VC3-TR?

A: Both parts share identical functional type, output configuration, reset logic, package, and operating temperature range. Voltage thresholds are within 0.08V of the primary part. The primary difference is reset timeout specification: substitute parts specify 140ms minimum versus 20ms minimum for the MIC803-30D2VC3-TR. Application-specific reset timing requirements must be evaluated.

Q: What is the difference between MAX803SEXR/V+T and MAX803TEXR/V+T?

A: Both parts are functionally equivalent with identical reset timeout (140ms minimum) and operating temperature range. The voltage threshold differs: MAX803SEXR/V+T at 2.93V and MAX803TEXR/V+T at 3.08V. Selection depends on the specific voltage monitoring requirement within the application.

Q: Are the substitute parts compatible with the same PCB layout?

A: Yes. All three parts use SC-70, SOT-323 surface mount package with identical pinout and footprint requirements.

Q: Do the substitute parts meet the same compliance standards?

A: All three parts are ROHS3 compliant, REACH unaffected, and have MSL 1 rating. The substitute parts carry additional AEC-Q100 automotive qualification, which the primary part does not specify.

Q: What inventory considerations apply to these parts?

A: The MIC803-30D2VC3-TR has 2100 Pcs in stock. MAX803SEXR/V+T has 7781 Pcs available, and MAX803TEXR/V+T has 847 Pcs available. Substitute parts offer higher availability for the MAX803SEXR/V+T variant.
