SCA100T-D07-1 Equivalent & Substitute Parts
Part Overview
The SCA100T-D07-1 is a dual-axis accelerometer manufactured by Murata Electronics, designed for motion sensing applications requiring ±12g acceleration measurement across X and Y axes. This component features SPI digital output, operates across a 4.75V to 5.25V supply range, and is housed in a 12-SMD surface mount package with gull wing leads.
The SCA100T-D07-1 has reached obsolete product status. Identifying equivalent and substitute components is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production or maintenance requirements for systems utilizing this accelerometer.

Substitute Part Grouping Explanation
Substitution of the SCA100T-D07-1 is evaluated based on the following critical parameters that define functional and mechanical compatibility:
Primary Substitution Criteria:
- Output interface type (SPI digital communication)
- Surface mount packaging (12-SMD configuration)
- Acceleration measurement capability across multiple axes
- Supply voltage compatibility or tolerance
- Operating temperature range coverage
- Moisture sensitivity classification
The SCA3300-D01 is identified as a manufacturer-recommended substitute. This substitution is based on shared SPI output architecture, identical 12-SMD surface mount packaging, and common moisture sensitivity rating. Both components are manufactured by Murata Electronics and maintain compatibility within the motion sensor product category.

Engineering Selection Recommendations
SCA3300-D01 Substitution Considerations:
The SCA3300-D01 is an active product with current manufacturing support from Murata Electronics, providing supply chain continuity for applications transitioning from the obsolete SCA100T-D07-1.
Compatibility Factors:
- Both components utilize SPI digital output protocol
- Both employ 12-SMD surface mount packaging with identical moisture sensitivity classification
- The SCA3300-D01 provides tri-axial measurement (X, Y, Z) compared to the dual-axis configuration of the SCA100T-D07-1
- Supply voltage differs: SCA100T-D07-1 operates at 4.75V–5.25V, while SCA3300-D01 requires 3.3V
- Acceleration range differs: SCA100T-D07-1 measures ±12g; SCA3300-D01 offers selectable ranges of ±1.5g, ±3g, or ±6g
- Package lead style differs: SCA100T-D07-1 uses gull wing leads; SCA3300-D01 uses flat leads
Compliance Status: The SCA3300-D01 is RoHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.
Frequently Asked Questions (FAQ)
Q: Can the SCA3300-D01 directly replace the SCA100T-D07-1 without circuit modifications?
A: Direct replacement requires evaluation of three critical factors: supply voltage (3.3V vs. 4.75–5.25V), acceleration range requirements (±1.5g/3g/6g vs. ±12g), and package lead geometry (flat lead vs. gull wing). Circuit redesign may be necessary to accommodate voltage differences and lead configuration changes.
Q: What is the primary advantage of substituting to the SCA3300-D01?
A: The SCA3300-D01 is an active product with ongoing manufacturing support, ensuring long-term component availability and supply chain stability compared to the obsolete SCA100T-D07-1.
Q: Are both components compatible with the same PCB footprint?
A: Both components use 12-SMD surface mount packaging; however, the lead style differs (gull wing vs. flat lead). PCB footprint verification is required before substitution.
Q: Does the SCA3300-D01 provide equivalent acceleration measurement capability?
A: The SCA3300-D01 offers selectable acceleration ranges (±1.5g, ±3g, ±6g), which do not include the ±12g range of the SCA100T-D07-1. Applications requiring ±12g measurement must evaluate whether lower range options are functionally acceptable.
Q: What supply voltage considerations apply to substitution?
A: The SCA100T-D07-1 operates at 4.75V–5.25V, while the SCA3300-D01 requires 3.3V. Power supply redesign or voltage regulation modifications may be necessary to support the substitute component.
Q: Are both components classified under the same moisture sensitivity level?
A: Yes, both the SCA100T-D07-1 and SCA3300-D01 are classified as MSL 3 (168 Hours), indicating identical moisture handling and storage requirements.
