Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AXO215 is determined by the following critical parameters:

• Package compatibility: 28-CLCC (J-Lead) surface mount configuration
• Interface compatibility: SPI digital output
• Functional similarity: Single-axis (X-axis) digital accelerometer
• Electrical compatibility: 5V supply voltage operation
• Bandwidth: 300Hz minimum bandwidth requirement
• Temperature range: Operating temperature envelope

The AXO315 qualifies as a substitute based on matching package type, interface protocol, axis configuration, bandwidth specification, and supply voltage compatibility. Both devices operate within overlapping temperature ranges and maintain the same physical footprint for PCB integration.

Parameter Comparison

Engineering Selection Recommendations

The AXO315 is the designated substitute for the obsolete AXO215 based on the following engineering criteria:

Package and Interface Compatibility: Both devices utilize the identical 28-CLCC (J-Lead) surface mount package, ensuring direct PCB footprint compatibility without layout modifications.

Functional Equivalence: Both accelerometers provide single-axis (X-axis) digital motion sensing with 300Hz bandwidth and SPI output interface, maintaining signal acquisition and data transmission compatibility.

Electrical Compatibility: The AXO315 operates at 5V, which falls within the AXO215's supply voltage range of 4.75 ~ 5.25V, ensuring compatibility with existing power distribution circuits.

Product Availability: The AXO315 maintains active product status with documented inventory availability, addressing the supply discontinuation of the obsolete AXO215.

Acceleration Range Consideration: The AXO315 specifies ±14g acceleration range compared to the AXO215's ±15g. This substitution is valid for applications where the measurement range does not require the full ±15g specification. Applications requiring the complete ±15g range must verify that system acceleration profiles remain within ±14g limits.

Temperature Range: The AXO315 provides an extended operating temperature range (-55°C ~ 105°C) compared to the AXO215 (-40°C ~ 85°C), offering improved thermal performance for demanding environments.

Frequently Asked Questions (FAQ)

Q: Can the AXO315 directly replace the AXO215 without PCB modifications?

A: Yes. Both devices share the identical 28-CLCC (J-Lead) package footprint and surface mount configuration. No PCB layout changes are required for physical integration.

Q: What is the primary difference between the AXO215 and AXO315?

A: The AXO315 specifies a ±14g acceleration range versus the AXO215's ±15g range. The AXO315 also offers an extended operating temperature range (-55°C ~ 105°C) and maintains active product status. Both devices maintain identical package type, SPI interface, 300Hz bandwidth, and X-axis configuration.

Q: Is the AXO315 suitable for applications requiring ±15g measurement capability?

A: The AXO315 is suitable only if system acceleration profiles remain within the ±14g specification. Applications requiring full ±15g measurement capability must verify that actual acceleration values do not exceed ±14g during operation.

Q: Are there any firmware or software changes required when substituting the AXO315 for the AXO215?

A: Both devices utilize identical SPI interface protocols and X-axis output configuration. Existing firmware and software implementations designed for the AXO215 are compatible with the AXO315 without modification, provided the acceleration range limitation is addressed in system design.

Q: What is the supply voltage requirement for the AXO315?

A: The AXO315 operates at 5V fixed supply voltage. This is compatible with the AXO215's nominal supply voltage of 5V (within the 4.75 ~ 5.25V range). Verify that existing power supply circuits provide stable 5V output.

Q: Does the AXO315 maintain RoHS compliance?

A: RoHS compliance status for the AXO315 is not specified in the provided technical data. Confirm RoHS certification status with the component supplier if regulatory compliance is required for your application.
