MMA5124LWR2 Equivalent & Substitute Parts

Part Overview

The MMA5124LWR2 is a digital accelerometer sensor designed for single-axis (Z-axis) motion detection with a measurement range of ±240g. This component features PCM and SPI output interfaces, operates across a supply voltage range of 4.2V to 17V, and is qualified for automotive applications under AEC-Q100 standards. The part is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MMA5124LWR2 is determined by the following critical parameters:

• Manufacturer alignment (NXP USA Inc.)
• Base product family (MMA5124 series)
• Package compatibility (16-QFN 6x6 form factor)
• Compliance certifications (ROHS3, AEC-Q100 automotive qualification)
• Environmental ratings (MSL 3, operating temperature range)

The MMA5124LVWR2 qualifies as a manufacturer-recommended substitute based on shared base product designation (MMA5124), identical package specification, and equivalent compliance profile. While output interface differs (PSI5 versus PCM/SPI), both variants maintain the same physical footprint and automotive-grade qualification requirements.

Parameter Comparison

Engineering Selection Recommendations

The MMA5124LVWR2 is designated as the manufacturer-recommended substitute for the obsolete MMA5124LWR2. Selection of this alternative is supported by:

• Active product status, ensuring continued availability and supply chain stability
• Identical package footprint (16-QFN 6x6), enabling direct PCB compatibility without layout modification
• Maintained automotive-grade qualification and AEC-Q100 compliance
• Equivalent environmental and regulatory certifications (ROHS3, REACH Unaffected, EAR99 classification)
• Consistent MSL rating and handling requirements

Interface protocol differences (PSI5 output on substitute versus PCM/SPI on original) require firmware and signal conditioning circuit evaluation during integration.

Frequently Asked Questions (FAQ)

Q: Can the MMA5124LVWR2 be used as a direct drop-in replacement for the MMA5124LWR2?

A: Physical package compatibility is confirmed (16-QFN 6x6 form factor). However, the output interface differs (PSI5 versus PCM/SPI), requiring circuit and firmware modifications to accommodate the alternative communication protocol.

Q: Are compliance certifications equivalent between these parts?

A: Yes. Both components maintain ROHS3 compliance, REACH Unaffected status, and automotive-grade AEC-Q100 qualification. MSL ratings and handling requirements are identical.

Q: Why is the MMA5124LWR2 listed as obsolete?

A: Product status reflects manufacturer discontinuation. The MMA5124LVWR2 represents the active alternative within the same product family.

Q: What are the key differences between these accelerometer variants?

A: The primary distinction is output interface specification. The MMA5124LWR2 provides PCM and SPI outputs, while the MMA5124LVWR2 implements PSI5 protocol. Both share identical package geometry and automotive qualification.

Q: Are there any supply voltage or temperature rating differences?

A: Only parameters explicitly provided in the component datasheets apply. Consult manufacturer documentation for complete electrical and thermal specifications of the MMA5124LVWR2 to confirm operational compatibility with your system design.
