FXLS8965AFR1 Equivalent & Substitute Parts

Part Overview

The FXLS8965AFR1 is a single-axis digital accelerometer manufactured by NXP USA Inc., designed to measure acceleration along the X-axis with selectable ranges of ±2g, ±4g, ±8g, or ±16g. The device is packaged in a 10-VFDFN (2x2mm) surface mount package and is ROHS3 compliant with MSL 1 rating.

This part has reached obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FXLS8965AFR1 are identified based on the following critical parameters that determine functional and mechanical compatibility:

Primary Substitution Criteria:

• Acceleration range capability: ±2g, ±4g, ±8g, ±16g (selectable)
• Package type: 10-VFDFN (2x2mm) surface mount
• Manufacturer: NXP USA Inc.
• Digital output interface compatibility
• RoHS3 compliance and environmental ratings

Direct Substitute: The FXLS8964AFR3 is identified as a direct manufacturer substitute. While this part extends functionality to three axes (X, Y, Z) compared to the single-axis FXLS8965AFR1, it maintains identical acceleration range selection, package form factor, and mounting specifications. The expanded axis capability does not preclude its use as a substitute, as single-axis operation can be achieved through firmware configuration.

Similar Substitute: The FXLS8964AFR1 provides an alternative with identical multi-axis capability and acceleration range as the FXLS8964AFR3, with the distinction of MSL 1 rating (matching the original part) versus MSL 3 for the AFR3 variant.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (FXLS8964AFR3): This part is actively manufactured and maintains full compatibility with the FXLS8965AFR1 acceleration range and package specifications. The addition of Y and Z axis sensing does not compromise single-axis operation. MSL 3 rating requires standard moisture control during storage and assembly. Automotive grade qualification (AEC-Q100) provides enhanced reliability assurance.

For Moisture-Sensitive Applications (FXLS8964AFR1): When MSL 1 (unlimited) moisture sensitivity rating is a design requirement, the FXLS8964AFR1 provides an active alternative with identical environmental specifications to the obsolete FXLS8965AFR1. This variant maintains the same multi-axis capability and acceleration range as the FXLS8964AFR3.

Both substitute parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Frequently Asked Questions (FAQ)

Q: Can the FXLS8964AFR3 directly replace the FXLS8965AFR1 in existing designs? A: Yes. Both parts share identical acceleration range selection (±2g through ±16g), package form factor (10-VFDFN 2x2mm), and surface mount configuration. The FXLS8964AFR3 provides additional X, Y, Z axis capability; designs requiring only X-axis data can operate the substitute in single-axis mode.

Q: What is the difference between FXLS8964AFR3 and FXLS8964AFR1? A: The primary difference is moisture sensitivity level: FXLS8964AFR3 has MSL 3 (168-hour limit), while FXLS8964AFR1 has MSL 1 (unlimited). Both are active products with identical acceleration ranges, bandwidth, output interfaces, and operating temperature specifications. Selection depends on moisture control requirements during component storage and assembly.

Q: Are there any package compatibility concerns when substituting? A: No. All three parts use the 10-VFDFN (2x2mm) surface mount package. PCB footprints and reflow profiles remain identical, requiring no design modifications.

Q: Does the FXLS8964 series maintain the same sensitivity specifications? A: The FXLS8964AFR3 and FXLS8964AFR1 both specify sensitivity as 1024 LSB/g at ±2g and 128 LSB/g at ±16g. The original FXLS8965AFR1 does not provide sensitivity specifications in available documentation.

Q: What compliance certifications apply to substitute parts? A: Both FXLS8964AFR3 and FXLS8964AFR1 are ROHS3 compliant and REACH unaffected. The FXLS8964AFR3 carries AEC-Q100 automotive qualification, providing additional reliability assurance for automotive applications.
