Key Parameters

Substitute Part Grouping Explanation

The SCA3300-D01-1 qualifies as a functional substitute based on the following criteria:

Shared Electrical Characteristics:

• Identical operating temperature range (-40°C ~ 125°C)
• Same manufacturer (Murata Electronics)
• Identical moisture sensitivity classification (MSL 3, 168 Hours)
• Identical ECCN and HTSUS classifications

Functional Compatibility:

• Both components provide SPI digital output capability
• Both are surface mount accelerometers within the motion sensor category
• Both support the required temperature operating envelope

Key Substitution Parameters:

• Acceleration range compatibility (±1.7g operation within SCA3300-D01-1's selectable ±1.5g, 3g, 6g range)
• SPI interface availability on both components
• Surface mount package compatibility for PCB integration

Parameter Comparison

Engineering Selection Recommendations

The SCA3300-D01-1 is the designated manufacturer substitute for the obsolete SCA1000-D01-1. Selection of this component is supported by:

• Active product status ensuring continued availability and supply chain support
• ROHS3 compliance certification meeting current regulatory requirements
• Identical operating temperature range and moisture sensitivity classification
• SPI interface compatibility with existing digital signal processing architectures
• Selectable acceleration range accommodating ±1.7g operation within the ±1.5g configuration

Design integration requires verification of supply voltage compatibility, as the SCA3300-D01-1 operates at 3V ~ 3.6V compared to the SCA1000-D01-1's 4.75V ~ 5.25V specification. The SCA3300-D01-1 provides three-axis measurement capability, adding Z-axis functionality not present in the original two-axis design.

Frequently Asked Questions (FAQ)

Q: Can the SCA3300-D01-1 directly replace the SCA1000-D01-1 without circuit modifications?

A: The SCA3300-D01-1 requires supply voltage circuit adjustment. The original component operates at 4.75V ~ 5.25V, while the substitute requires 3V ~ 3.6V. SPI interface compatibility is maintained. Analog output functionality is not available on the substitute; designs dependent on analog output require alternative solutions.

Q: What is the primary reason for substitution?

A: The SCA1000-D01-1 is classified as obsolete. The SCA3300-D01-1 is the active equivalent from the same manufacturer, ensuring continued component availability and regulatory compliance.

Q: Does the SCA3300-D01-1 support the same acceleration range?

A: The SCA3300-D01-1 provides selectable acceleration ranges of ±1.5g, 3g, and 6g. The original ±1.7g operation falls within the ±1.5g selectable configuration of the substitute.

Q: Are there package compatibility considerations?

A: Both components are surface mount devices. The SCA1000-D01-1 uses a 12-SMD package, while the SCA3300-D01-1 uses a nonstandard package. PCB layout verification is required to confirm physical fit and pin alignment.

Q: What certifications apply to the substitute component?

A: The SCA3300-D01-1 holds ROHS3 compliance and REACH unaffected status. Both components share identical ECCN (EAR99) and HTSUS (9031.80.8085) classifications.
