Key Parameters

Substitute Part Grouping Explanation

Substitution of the KXCNL-1010-PR is determined by the following critical parameters:

Interface Compatibility: Both the main part and substitute must support I2C digital communication protocol.

Axis Configuration: Three-axis (X, Y, Z) acceleration measurement capability is required.

Supply Voltage Range: Operating voltage must encompass or be compatible with 1.71V ~ 3.6V.

Operating Temperature Range: The substitute must support -40°C ~ 85°C operation.

Acceleration Range Overlap: The substitute must support at least the ±2g and ±8g ranges present in the main part.

Mounting and Package: Surface mount technology with compatible LGA packaging.

Regulatory Compliance: ROHS3 compliance and equivalent MSL rating.

The KXTJ3-1057 meets these substitution criteria through identical I2C interface, three-axis configuration, matching voltage supply range, equivalent temperature range, overlapping acceleration ranges (±2g through ±16g), surface mount LGA packaging, and equivalent regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

The KXTJ3-1057 is suitable as a substitute for the obsolete KXCNL-1010-PR based on the following engineering criteria:

Product Status: The KXTJ3-1057 maintains active product status with Kionix Inc., ensuring continued availability, technical support, and supply chain reliability compared to the obsolete KXCNL-1010-PR.

Regulatory Compliance: Both devices maintain ROHS3 compliance and equivalent MSL ratings, satisfying environmental and manufacturing process requirements.

Functional Equivalence: Identical I2C interface, three-axis configuration, supply voltage range, and operating temperature range ensure functional compatibility at the system level.

Acceleration Range: The KXTJ3-1057 provides extended acceleration range capability (±2g through ±16g) while maintaining full overlap with the KXCNL-1010-PR's operational ranges (±2g, ±4g, ±8g).

Physical Considerations: The package footprint differs (16-VFLGA 3x3 versus 12-VFLGA 2x2), requiring PCB layout modification and re-qualification of the physical implementation.

Frequently Asked Questions (FAQ)

Q: Can the KXTJ3-1057 directly replace the KXCNL-1010-PR without firmware changes?

A: The I2C interface and register structure are compatible, but firmware validation is required due to differences in acceleration range options and bandwidth characteristics. The KXTJ3-1057 operates at a fixed 800Hz bandwidth, whereas the KXCNL-1010-PR supports adjustable bandwidth from 1.56Hz to 800Hz.

Q: What is the primary difference between these two accelerometers?

A: The KXCNL-1010-PR features adjustable bandwidth (1.56Hz ~ 800Hz) and a 16-pin package, while the KXTJ3-1057 provides fixed 800Hz bandwidth, extended acceleration range (±16g maximum), and a smaller 12-pin package footprint.

Q: Are there PCB layout considerations when substituting these parts?

A: Yes. The package footprint differs significantly (16-VFLGA 3x3 versus 12-VFLGA 2x2). PCB redesign is necessary, and the smaller footprint of the KXTJ3-1057 may reduce board space requirements.

Q: Do both devices support the same supply voltage range?

A: Yes. Both the KXCNL-1010-PR and KXTJ3-1057 operate across 1.71V to 3.6V, ensuring compatibility with existing power supply designs.

Q: What acceleration ranges are common to both devices?

A: Both devices support ±2g, ±4g, and ±8g acceleration ranges. The KXTJ3-1057 additionally supports ±16g, which is not available on the KXCNL-1010-PR.

Q: Are both devices RoHS compliant?

A: Yes. Both the KXCNL-1010-PR and KXTJ3-1057 are ROHS3 compliant with identical MSL ratings of 3 (168 Hours).
