SPA2629LR5H-B Equivalent & Substitute Parts

Part Overview

The SPA2629LR5H-B is an active MEMS analog omnidirectional microphone manufactured by Knowles, part of the SiSonic™ Zero-Height Mic™ series. This component operates across a frequency range of 100 Hz to 10 kHz with a sensitivity of -38dB ±3dB @ 94dB SPL and supports supply voltages from 1.5 V to 3.6 V. The device is classified as Active product status and is RoHS Compliant with MSL 1 (Unlimited moisture sensitivity level). Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances for this MEMS microphone category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPA2629LR5H-B is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Output Type: Analog (required match)
• Direction: Omnidirectional (required match)
• Type: MEMS (Silicon) (required match)
• Frequency Range: Must encompass or overlap the 100 Hz ~ 10 kHz range
• Sensitivity: Within acceptable tolerance for the application
• Voltage Range: Must support operation within the 1.5 V ~ 3.6 V envelope or be compatible with the system supply voltage
• Port Location: Bottom (required match for PCB integration)

Compliance & Environmental Requirements:

• RoHS Status: Compliant designation required
• MSL: Level 1 (Unlimited) preferred for manufacturing compatibility
• REACH Status: REACH Unaffected designation required

The substitute part SPV08A0LR5H-1 meets these criteria as an equivalent MEMS analog omnidirectional microphone from Knowles with compatible electrical characteristics and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the SPA2629LR5H-B and SPV08A0LR5H-1 are Active product status components from Knowles with full RoHS and REACH compliance. Selection between these parts depends on system-level requirements:

The SPA2629LR5H-B operates with a lower minimum supply voltage (1.5 V) and lower supply current (165 µA), making it suitable for battery-powered or low-power applications with voltage constraints below 2.3 V.

The SPV08A0LR5H-1 provides an extended lower frequency response (20 Hz vs. 100 Hz) and tighter sensitivity tolerance (±1dB vs. ±3dB), with slightly higher supply current (200 µA). This part is suitable for applications requiring enhanced low-frequency capture or stricter sensitivity specifications, provided the system supply voltage is 2.3 V or higher.

Both components maintain MSL 1 (Unlimited) classification and are suitable for standard manufacturing environments without special moisture control requirements.

Frequently Asked Questions (FAQ)

Q: Can SPV08A0LR5H-1 replace SPA2629LR5H-B in all applications?

A: Substitution is valid when the system supply voltage is 2.3 V or higher. If your application requires operation below 2.3 V, the SPA2629LR5H-B is the only suitable option. Additionally, the SPV08A0LR5H-1 has a lower frequency range floor (20 Hz vs. 100 Hz), which may affect applications requiring rejection of frequencies below 100 Hz.

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

A: The primary differences are voltage range (SPA2629LR5H-B: 1.5 V ~ 3.6 V; SPV08A0LR5H-1: 2.3 V ~ 3.6 V), sensitivity specification (SPA2629LR5H-B: -38dB ±3dB; SPV08A0LR5H-1: -42dB ±1dB), and supply current (SPA2629LR5H-B: 165 µA; SPV08A0LR5H-1: 200 µA).

Q: Are there packaging differences between these parts?

A: The SPA2629LR5H-B uses standard packaging, while the SPV08A0LR5H-1 is supplied in Tape & Reel (TR) format with solder pads. Both maintain identical port location (Bottom) and physical compatibility for PCB integration.

Q: Do both parts meet the same compliance standards?

A: Both parts are RoHS Compliant, REACH Unaffected, and classified as MSL 1 (Unlimited). The SPV08A0LR5H-1 carries ROHS3 designation, which represents a more recent RoHS compliance standard. Both are suitable for standard manufacturing environments.

Q: Which part should I select for low-power applications?

A: The SPA2629LR5H-B is the preferred choice for low-power applications due to its lower minimum supply voltage (1.5 V) and lower supply current (165 µA). The SPV08A0LR5H-1 requires a minimum of 2.3 V and draws 200 µA.
