INMP510ACEZ-R0 Equivalent & Substitute Parts

Part Overview

The INMP510ACEZ-R0 is a MEMS analog omnidirectional microphone manufactured by TDK InvenSense, designed for applications requiring 60 Hz to 20 kHz frequency response with -38dB sensitivity at 94dB SPL. The device operates across a 1.5 V to 3.63 V supply range and delivers 65dB signal-to-noise ratio performance in a compact 3.35mm × 2.50mm form factor with bottom-mounted solder pad termination.

This part carries a "Not For New Designs" product status, necessitating identification of active alternative components that maintain functional and mechanical compatibility for ongoing production and design requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the INMP510ACEZ-R0 is determined by strict alignment across the following critical parameters:

Mechanical Compatibility: Identical package dimensions (3.35mm × 2.50mm), height (1.10mm maximum), rectangular shape, bottom port location, and solder pad termination ensure direct PCB footprint compatibility.

Electrical Compatibility: MEMS silicon construction with analog output, omnidirectional pickup pattern, and nominal -38dB sensitivity at 94dB SPL establish functional equivalence. Voltage supply range must accommodate the original operating window or provide overlap. Current consumption and impedance characteristics must remain within acceptable operational margins.

Frequency Response: The substitute must cover the 60 Hz to 20 kHz range or extend beyond it without performance degradation in the critical audio band.

Compliance & Status: Active product status ensures ongoing availability and manufacturing support. RoHS3 compliance and REACH unaffected status maintain regulatory alignment with the original component.

Parameter Comparison

Engineering Selection Recommendations

The MP23AB02TR from STMicroelectronics qualifies as a direct substitute for the INMP510ACEZ-R0 based on mechanical and electrical parameter alignment. Both components share identical package dimensions, height, port location, and solder pad termination, enabling direct PCB footprint compatibility without layout modification.

Electrical performance remains functionally equivalent: both deliver -38dB nominal sensitivity at 94dB SPL with omnidirectional MEMS silicon construction and analog output. The MP23AB02TR operates within the INMP510ACEZ-R0 supply voltage range (1.8 V rated falls within 1.5 V to 3.63 V specification) and demonstrates lower supply current (220 µA versus 250 µA), providing favorable power consumption characteristics.

The MP23AB02TR carries Active product status with ongoing manufacturing support, addressing the obsolescence concern of the INMP510ACEZ-R0 "Not For New Designs" designation. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity.

Moisture sensitivity level differs: the MP23AB02TR requires MSL 3 handling (168-hour floor life) compared to the INMP510ACEZ-R0 MSL 1 (unlimited). This necessitates implementation of appropriate moisture control procedures during component storage and assembly operations.

Frequently Asked Questions (FAQ)

Q: Can the MP23AB02TR replace the INMP510ACEZ-R0 without PCB modifications?

A: Yes. Both components share identical package dimensions (3.35mm × 2.50mm), height (1.10mm), rectangular shape, bottom port location, and solder pad termination. Direct footprint compatibility is confirmed; no PCB layout changes are required.

Q: What are the key electrical differences between these microphones?

A: Both deliver -38dB nominal sensitivity at 94dB SPL with omnidirectional MEMS construction. The MP23AB02TR extends lower frequency response (20 Hz versus 60 Hz minimum) and operates at slightly lower supply current (220 µA versus 250 µA). Signal-to-noise ratio differs by 1dB (64dB versus 65dB), which remains within acceptable audio performance margins.

Q: Does the MP23AB02TR operate at the same supply voltage as the INMP510ACEZ-R0?

A: The MP23AB02TR is rated at 1.8 V, which falls within the INMP510ACEZ-R0 operating range of 1.5 V to 3.63 V. Designs operating at 1.8 V supply voltage experience direct compatibility. Designs requiring operation at the extremes of the INMP510 range (below 1.8 V or above 3.63 V) require circuit evaluation.

Q: What is the impact of the different moisture sensitivity levels?

A: The INMP510ACEZ-R0 carries MSL 1 (unlimited floor life), while the MP23AB02TR requires MSL 3 handling (168-hour floor life after moisture exposure). Assembly operations must implement appropriate desiccant storage and bake-out procedures for the MP23AB02TR to prevent moisture-induced solder joint degradation.

Q: Are both components RoHS and REACH compliant?

A: Yes. Both the INMP510ACEZ-R0 and MP23AB02TR are ROHS3 compliant and REACH unaffected, maintaining identical regulatory status for applications subject to these requirements.

Q: Why is the INMP510ACEZ-R0 marked "Not For New Designs"?

A: This designation indicates the component is in end-of-life phase with no new production planned. The MP23AB02TR carries Active status, confirming ongoing manufacturing availability and long-term supply continuity for new and existing production programs.
