SCA1020-D08 Equivalent & Substitute Parts

Part Overview

The SCA1020-D08 is a dual-axis accelerometer manufactured by Murata Electronics, designed for motion sensing applications requiring Y and Z axis acceleration measurement at ±1.7g range with analog and SPI output options. This component is classified as obsolete, necessitating identification of active equivalent parts for new designs and production continuity. The SCA1020-D08 operates at 4.75V to 5.25V supply voltage with 50Hz bandwidth and includes an integrated temperature sensor in a 12-SMD surface mount package.

Key Parameters

Substitute Part Grouping Explanation

The SCA3300-D01-1 is identified as the manufacturer-recommended substitute for the SCA1020-D08. Substitution eligibility is determined by the following criteria:

Functional Compatibility Parameters:

• Acceleration measurement capability across multiple axes
• Digital output interface (SPI) for data communication
• Surface mount technology for PCB integration
• Moisture sensitivity classification alignment

Key Differences Requiring Design Consideration:

• Axis configuration: SCA1020-D08 measures Y, Z axes; SCA3300-D01-1 measures X, Y, Z axes (tri-axial)
• Acceleration range: SCA1020-D08 fixed at ±1.7g; SCA3300-D01-1 selectable (±1.5g, ±3g, ±6g)
• Output type: SCA1020-D08 supports analog and SPI; SCA3300-D01-1 SPI only
• Supply voltage: SCA1020-D08 requires 4.75V ~ 5.25V; SCA3300-D01-1 operates at 3V ~ 3.6V
• Product status: SCA1020-D08 obsolete; SCA3300-D01-1 active

Parameter Comparison

Engineering Selection Recommendations

The SCA3300-D01-1 is the active equivalent for the obsolete SCA1020-D08. Selection of this substitute requires verification of the following design parameters:

Voltage Supply Compatibility: The SCA3300-D01-1 operates at 3V ~ 3.6V, which differs from the SCA1020-D08 supply range of 4.75V ~ 5.25V. Power supply redesign or voltage regulation may be necessary.

Output Interface: The SCA3300-D01-1 provides SPI output only, eliminating analog output capability. Applications requiring analog signal output require alternative component selection or signal conditioning circuitry.

Axis Configuration: The SCA3300-D01-1 provides tri-axial measurement (X, Y, Z), whereas the SCA1020-D08 provides dual-axis measurement (Y, Z). Applications utilizing only Y and Z axes can operate with the additional X-axis data unused.

Acceleration Range Selection: The SCA3300-D01-1 offers selectable acceleration ranges (±1.5g, ±3g, ±6g). Applications requiring ±1.7g measurement must select the ±3g or ±6g range, with corresponding sensitivity adjustments.

Compliance Status: The SCA3300-D01-1 carries ROHS3 compliance and REACH unaffected status, supporting modern regulatory requirements. The SCA1020-D08 compliance status is not specified.

Frequently Asked Questions (FAQ)

Q: Can the SCA3300-D01-1 directly replace the SCA1020-D08 without circuit modifications?

A: Direct replacement is not possible without circuit modifications. The SCA3300-D01-1 requires 3V ~ 3.6V supply voltage compared to the SCA1020-D08 requirement of 4.75V ~ 5.25V. Additionally, the SCA3300-D01-1 provides SPI output only, eliminating analog output capability present in the SCA1020-D08.

Q: What is the sensitivity difference between these parts?

A: The SCA1020-D08 provides fixed sensitivity of 1200 mV/g. The SCA3300-D01-1 provides variable sensitivity dependent on selected acceleration range: 5400 LSB/g at ±1.5g, down to 1350 LSB/g at ±6g. Direct mV/g sensitivity is not specified for the SCA3300-D01-1.

Q: Does the SCA3300-D01-1 measure the same axes as the SCA1020-D08?

A: The SCA1020-D08 measures Y and Z axes only. The SCA3300-D01-1 measures X, Y, and Z axes. Applications requiring only Y and Z axis data can utilize the SCA3300-D01-1 with X-axis data disregarded in firmware processing.

Q: What packaging differences exist between these parts?

A: The SCA1020-D08 uses 12-SMD Gull Wing package. The SCA3300-D01-1 uses a nonstandard package configuration. Physical footprint verification is required before PCB layout modification.

Q: Are both parts available in the same moisture sensitivity classification?

A: Yes, both the SCA1020-D08 and SCA3300-D01-1 carry Moisture Sensitivity Level 3 (168 Hours) classification, indicating equivalent handling and storage requirements.

Q: What is the bandwidth difference?

A: The SCA1020-D08 specifies 50Hz bandwidth. The SCA3300-D01-1 bandwidth is not specified in the provided parameters. Bandwidth verification is required for applications with specific frequency response requirements.
