Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the INMP510ACEZ-R7 is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• MEMS silicon-based analog microphone architecture
• Omnidirectional pickup pattern
• Sensitivity within -38dB range at 94dB SPL
• Solder pad termination on bottom port location
• Rectangular form factor matching 3.35mm × 2.50mm footprint and 1.10mm maximum height
• Analog output type

Operational Compatibility Criteria:

• Frequency response spanning minimum 60 Hz to 20 kHz
• Supply voltage compatibility within specified operating range
• Signal-to-noise ratio performance ≥64dB

The MP23AB02TR from STMicroelectronics satisfies all mandatory compatibility criteria and maintains operational performance within acceptable engineering tolerances for direct substitution in existing designs.

Parameter Comparison

Engineering Selection Recommendations

The MP23AB02TR qualifies as a direct substitute for the INMP510ACEZ-R7 based on the following engineering criteria:

Functional Equivalence: Both components deliver identical omnidirectional MEMS analog microphone functionality with matching -38dB sensitivity specifications, solder pad termination, and physical form factor. The MP23AB02TR maintains the same 3.35mm × 2.50mm footprint and 1.10mm height, enabling direct PCB layout compatibility without redesign.

Compliance Alignment: Both parts maintain ROHS3 compliance and carry identical ECCN and HTSUS classifications, ensuring regulatory and supply chain continuity.

Product Status Advantage: The MP23AB02TR carries "Active" product status, providing long-term availability and manufacturing support for ongoing production requirements, whereas the INMP510ACEZ-R7 is designated "Not For New Designs."

Performance Tolerance: The MP23AB02TR operates within acceptable engineering margins across all critical parameters. The 1dB variance in S/N ratio (64dB vs. 65dB) and ±1dB sensitivity tolerance expansion remain within typical application requirements for analog microphone systems.

Supply Considerations: The MP23AB02TR demonstrates lower supply current consumption (220 µA vs. 250 µA), providing marginal power efficiency benefits in battery-powered applications.

Frequently Asked Questions (FAQ)

Q: Can the MP23AB02TR be used as a direct PCB replacement for the INMP510ACEZ-R7?

A: Yes. Both components share identical footprint dimensions (3.35mm × 2.50mm), height (1.10mm), and solder pad termination configuration. No PCB layout modifications are required for mechanical or electrical substitution.

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

A: The primary differences are product status (MP23AB02TR is active; INMP510ACEZ-R7 is not for new designs), frequency response lower limit (MP23AB02TR extends to 20 Hz vs. 60 Hz), S/N ratio (64dB vs. 65dB), and supply current (220 µA vs. 250 µA). Sensitivity specifications remain equivalent at -38dB ±tolerance @ 94dB SPL.

Q: Is the MP23AB02TR compatible with existing circuit designs using the INMP510ACEZ-R7?

A: Yes. The MP23AB02TR operates within the INMP510ACEZ-R7 supply voltage range (1.8 V falls within 1.5 V ~ 3.63 V specification) and maintains analog output compatibility. No circuit modifications are necessary for functional substitution.

Q: What is the MSL (Moisture Sensitivity Level) difference, and does it affect handling?

A: The INMP510ACEZ-R7 carries MSL 1 (unlimited shelf life), while the MP23AB02TR carries MSL 3 (168-hour floor life limit). The MP23AB02TR requires standard moisture control handling procedures during storage and assembly, consistent with industry MSL 3 component protocols.

Q: Are both components RoHS compliant?

A: Yes. Both the INMP510ACEZ-R7 and MP23AB02TR are ROHS3 compliant and carry identical REACH unaffected status, ensuring regulatory alignment for EU and global markets.

Q: Which component should be selected for new product designs?

A: The MP23AB02TR is the appropriate selection for new designs due to its active product status and long-term manufacturing support. The INMP510ACEZ-R7 is designated "Not For New Designs" and should be reserved for legacy product support only.
