FXLS8964AFR1 Equivalent & Substitute Parts

Part Overview

The FXLS8964AFR1 is a digital 3-axis accelerometer manufactured by NXP USA Inc., designed for motion sensing applications requiring multi-axis acceleration measurement. This component operates across ±2g, 4g, 8g, and 16g acceleration ranges with a 1.6kHz bandwidth and supports both I2C and SPI digital output interfaces. The device is classified as Active product status and carries automotive-grade qualification under AEC-Q100 standards. Substitute parts are identified when equivalent electrical and mechanical parameters are required for design flexibility, inventory optimization, or supply chain continuity while maintaining functional compatibility within the application circuit.

Substitute Part Grouping Explanation

Substitute parts for the FXLS8964AFR1 are qualified based on strict electrical and mechanical parameter equivalence. All identified substitutes maintain identical specifications across the following critical parameters: 3-axis acceleration measurement capability, ±2g through ±16g selectable acceleration ranges, 1.6kHz bandwidth, I2C and SPI digital output interfaces, 1.71V to 3.6V supply voltage operation, -40°C to 105°C operating temperature range, automotive-grade classification, AEC-Q100 qualification, and 10-DFN (2x2) surface mount package configuration. Substitution is valid when these parameters are matched across all candidate parts. Differences in packaging format (Cut Tape versus Digi-Reel), moisture sensitivity level (MSL), and inventory availability do not affect functional equivalence but may influence procurement and handling procedures.

Engineering Selection Recommendations

All substitute parts listed—FXLS8964AFR3, FXLS8967AFR3, and FXLS8974CFR3—are functionally equivalent to the FXLS8964AFR1 based on electrical and mechanical parameter matching. Each substitute maintains Active product status, automotive-grade classification, and AEC-Q100 qualification. All parts are RoHS3 compliant and REACH unaffected, satisfying regulatory requirements for automotive and industrial applications.

Selection between the main part and substitutes should be based on availability and packaging format requirements. The FXLS8964AFR1 is supplied in standard packaging with MSL 1 (Unlimited moisture sensitivity level). The FXLS8964AFR3 and FXLS8974CFR3 are supplied in Cut Tape and Digi-Reel formats with MSL 1 (Unlimited). The FXLS8967AFR3 is supplied in Cut Tape and Digi-Reel formats with MSL 1 (Unlimited). All parts support identical circuit integration and firmware implementation without modification.

Frequently Asked Questions (FAQ)

Q: Can FXLS8964AFR3 be used as a direct replacement for FXLS8964AFR1 in production?

A: Yes. Both parts are electrically and mechanically equivalent across all specified parameters. The primary difference is packaging format. FXLS8964AFR3 is supplied in Cut Tape and Digi-Reel formats, while FXLS8964AFR1 uses standard packaging. No circuit redesign or firmware changes are required.

Q: What is the difference between FXLS8967AFR3 and FXLS8974CFR3?

A: Both parts are parametrically equivalent to FXLS8964AFR1 across all electrical and mechanical specifications. Differences exist only in part numbering and internal device architecture, which do not affect functional performance in applications requiring 3-axis acceleration measurement with ±2g to ±16g ranges, 1.6kHz bandwidth, and I2C/SPI interfaces.

Q: Are all substitute parts automotive-qualified?

A: Yes. All substitute parts carry automotive-grade classification and AEC-Q100 qualification, matching the FXLS8964AFR1 specification. All are suitable for automotive and industrial applications requiring automotive-level reliability standards.

Q: Does moisture sensitivity level (MSL) affect circuit performance?

A: No. MSL classification affects component handling, storage, and soldering procedures but does not impact electrical performance or functional operation. MSL 1 (Unlimited) parts require standard moisture control during storage and assembly. MSL 3 (168 Hours) parts require more stringent moisture control protocols.

Q: Can these parts be used interchangeably in the same PCB assembly?

A: Yes. All substitute parts use identical 10-DFN (2x2) surface mount packages with matching pin configurations. PCB layout, footprint, and solder reflow profiles remain unchanged across all equivalent parts.

Q: What compliance certifications apply to all substitute parts?

A: All parts are RoHS3 compliant and REACH unaffected. These certifications apply uniformly across FXLS8964AFR1, FXLS8964AFR3, FXLS8967AFR3, and FXLS8974CFR3.
