MMA6813BKW Equivalent & Substitute Parts

Part Overview

The MMA6813BKW is a digital accelerometer designed for motion sensing applications requiring dual-axis (X, Y) acceleration measurement. This device operates with a ±50g acceleration range and communicates via SPI interface, making it suitable for automotive-grade applications. The MMA6813BKW carries a "Not For New Designs" product status, indicating it has been superseded in the manufacturer's product line. Identifying equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and access components with active production status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MMA6813BKW is determined by strict alignment across the following critical parameters:

• Acceleration Range: ±50g (exact match required)
• Axis Configuration: X, Y dual-axis (exact match required)
• Output Interface: SPI (exact match required)
• Sensitivity (LSB/g): 9.766 (exact match required)
• Supply Voltage Range: 3.135V ~ 5.25V (exact match required)
• Operating Temperature Range: -40°C ~ 105°C (exact match required)
• Package / Case: 16-QFN Exposed Pad (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Grade: Automotive (exact match required)
• Qualification: AEC-Q100 (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level (MSL): 3 (168 Hours) (exact match required)

The MMA6813BKCWR2 meets all substitution criteria as a direct equivalent. The primary distinction is product status: MMA6813BKW is classified as "Not For New Designs," while MMA6813BKCWR2 maintains "Active" status with higher inventory availability (5496 Pcs vs. 737 Pcs).

Parameter Comparison

Engineering Selection Recommendations

The MMA6813BKCWR2 is the direct equivalent substitute for the MMA6813BKW. Both components are manufactured by NXP USA Inc. and maintain identical electrical and mechanical specifications across all critical parameters. The MMA6813BKCWR2 is preferred for new designs and ongoing production due to its "Active" product status, ensuring long-term availability and manufacturer support. Both parts satisfy automotive-grade requirements with AEC-Q100 qualification and ROHS3 compliance, making them suitable for automotive motion sensing applications operating across the -40°C to 105°C temperature range.

Frequently Asked Questions (FAQ)

Q: Can MMA6813BKCWR2 be used as a direct replacement for MMA6813BKW?

A: Yes. The MMA6813BKCWR2 is a direct equivalent substitute. All electrical parameters (acceleration range, sensitivity, output interface, supply voltage, operating temperature), mechanical specifications (package type, mounting configuration), and compliance certifications (AEC-Q100, ROHS3) are identical between the two part numbers.

Q: Why is MMA6813BKW marked as "Not For New Designs"?

A: The "Not For New Designs" status indicates that NXP USA Inc. has transitioned this component to end-of-life in their product portfolio. The MMA6813BKCWR2 represents the active production equivalent. For new designs, MMA6813BKCWR2 should be specified to ensure supply chain continuity and manufacturer support.

Q: Are there any package or pinout differences between these parts?

A: No. Both the MMA6813BKW and MMA6813BKCWR2 use the 16-QFN Exposed Pad package with identical pinout and mechanical dimensions. PCB layout and footprint designs are interchangeable.

Q: What is the difference in inventory availability?

A: MMA6813BKW has 737 pieces in stock, while MMA6813BKCWR2 has 5496 pieces available. The higher inventory of the active part number reflects ongoing production and supply chain prioritization.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the MMA6813BKW and MMA6813BKCWR2 carry automotive-grade classification with AEC-Q100 qualification, meeting automotive industry reliability and quality standards for motion sensing applications.

Q: What is the Moisture Sensitivity Level (MSL) rating?

A: Both parts have an MSL rating of 3 with a floor life of 168 hours. This indicates standard moisture sensitivity handling requirements for surface mount assembly processes.
