FXLS8964AFR3 Equivalent & Substitute Parts

Part Overview

The FXLS8964AFR3 is a digital 3-axis accelerometer manufactured by NXP USA Inc., designed for motion sensing applications requiring multi-axis acceleration measurement. This device operates across ±2g, 4g, 8g, and 16g acceleration ranges with a 1.6kHz bandwidth and supports both I2C and SPI digital output interfaces. The component is classified as Active product status and carries automotive-grade qualification under AEC-Q100 standards. Substitute parts are identified when equivalent electrical parameters, mechanical packaging, and compliance certifications align with the primary device specifications, enabling direct replacement in circuit designs without functional degradation.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FXLS8964AFR3 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Acceleration range: ±2g, 4g, 8g, 16g
• Sensitivity specification: 1024 (±2g) ~ 128 (±16g) LSB/g
• Bandwidth: 1.6kHz
• Output interface: I2C and SPI support
• Supply voltage range: 1.71V ~ 3.6V
• Operating temperature: -40°C ~ 105°C

Mechanical Equivalence Criteria:

• Package type: 10-VFDFN (10-DFN 2x2)
• Mounting type: Surface Mount
• Supplier device package: 10-DFN (2x2)

Compliance Equivalence Criteria:

• Manufacturer: NXP USA Inc.
• Product status: Active
• RoHS compliance: ROHS3 Compliant
• REACH status: REACH Unaffected
• Automotive grade qualification: AEC-Q100

All three substitute parts (FXLS8964AFR3, FXLS8967AFR3, FXLS8974CFR3) meet these core equivalence requirements. Differences in moisture sensitivity level (MSL) and inventory availability do not affect functional substitution capability.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain full electrical and mechanical compatibility with the FXLS8964AFR3 primary device. Selection between equivalent parts is based on the following factors:

FXLS8964AFR3 (Primary and Substitute): This part carries automotive-grade qualification under AEC-Q100 standards with MSL rating of 3 (168 Hours). Current inventory: 3400 pieces. This specification is appropriate for automotive and industrial applications requiring formal qualification documentation.

FXLS8967AFR3: This part provides equivalent electrical and mechanical specifications with improved moisture handling characteristics (MSL 1, Unlimited). No automotive-grade or AEC-Q100 qualification is specified. Current inventory: 11900 pieces. This part is suitable for non-automotive applications or environments with extended storage requirements prior to assembly.

FXLS8974CFR3: This part provides equivalent electrical and mechanical specifications with improved moisture handling characteristics (MSL 1, Unlimited). No automotive-grade or AEC-Q100 qualification is specified. Current inventory: 2300 pieces. This part is suitable for non-automotive applications or environments with extended storage requirements prior to assembly.

For automotive applications requiring AEC-Q100 compliance, the FXLS8964AFR3 remains the specified choice. For non-automotive applications, FXLS8967AFR3 and FXLS8974CFR3 offer equivalent performance with superior moisture tolerance.

Frequently Asked Questions (FAQ)

Q: Can FXLS8967AFR3 or FXLS8974CFR3 be used as direct replacements for FXLS8964AFR3 in automotive applications?

A: FXLS8967AFR3 and FXLS8974CFR3 provide identical electrical performance and mechanical packaging. However, these parts do not carry specified automotive-grade qualification or AEC-Q100 certification. For applications requiring automotive compliance documentation, FXLS8964AFR3 is the appropriate selection. For non-automotive applications, substitution is electrically and mechanically valid.

Q: What is the significance of the MSL (Moisture Sensitivity Level) difference between parts?

A: FXLS8964AFR3 carries MSL 3 (168 Hours), indicating moisture sensitivity requiring controlled storage and handling within 168 hours of package opening. FXLS8967AFR3 and FXLS8974CFR3 carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. MSL differences do not affect electrical performance but impact storage, handling, and assembly procedures.

Q: Are all substitute parts available in the same packaging format?

A: All parts are supplied in Cut Tape (CT) and Digi-Reel® packaging with identical 10-DFN (2x2) surface mount package specifications. Packaging format is consistent across all equivalent parts.

Q: Do the substitute parts support identical communication protocols?

A: All parts support both I2C and SPI digital output interfaces with identical bandwidth (1.6kHz), acceleration range (±2g, 4g, 8g, 16g), and sensitivity specifications (1024 to 128 LSB/g). Communication protocol compatibility is complete.

Q: What is the operating temperature range for all substitute parts?

A: All parts operate across -40°C to 105°C with identical supply voltage range of 1.71V to 3.6V. Operating conditions are equivalent across all substitute parts.

Q: Are there any differences in the features provided by each part?

A: All parts include adjustable bandwidth, sleep mode, and integrated temperature sensor functionality. Feature sets are identical across FXLS8964AFR3, FXLS8967AFR3, and FXLS8974CFR3.
