SCA1000-D10 Equivalent & Substitute Parts

Part Overview

The SCA1000-D10 is a dual-axis accelerometer manufactured by Murata Electronics, designed for motion sensing applications requiring analog and SPI digital output. This 12-SMD surface mount device operates at ±1.7g acceleration range with 50Hz bandwidth and 1200mV/g sensitivity. The product is currently obsolete, necessitating identification of functionally compatible alternatives for ongoing design requirements and component procurement.

Key Parameters

Substitute Part Grouping Explanation

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

Common Functional Parameters:

• Manufacturer: Murata Electronics (same manufacturer ensures design continuity and support)
• Category: Motion Sensors (identical application domain)
• Mounting Type: Surface Mount (compatible with existing PCB assembly processes)
• MSL Rating: 3 (168 Hours) (equivalent moisture sensitivity handling)

Substitution Logic: The SCA3300-D01-1 provides digital SPI output, which directly replaces the SPI capability of the SCA1000-D10. While the SCA3300-D01-1 offers tri-axis (X, Y, Z) measurement versus the dual-axis (Y, Z) configuration of the original part, the Y and Z axes remain functionally equivalent. The acceleration range options (±1.5g, ±3g, ±6g) include the ±1.5g setting, which provides comparable sensitivity to the original ±1.7g specification for applications not requiring the exact 1.7g threshold.

Key Differences Requiring Design Review:

• Supply voltage: SCA3300-D01-1 operates at 3V ~ 3.6V versus SCA1000-D10 at 4.75V ~ 5.25V
• Output type: SCA3300-D01-1 is digital-only (SPI); analog output is not available
• Package form: SCA3300-D01-1 uses nonstandard package versus 12-SMD gull wing

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The SCA3300-D01-1 is suitable as a substitute for the obsolete SCA1000-D10 when the following conditions are met:

1. Voltage Supply Redesign: The design must accommodate a 3V ~ 3.6V supply instead of 4.75V ~ 5.25V. This requires power supply modification or voltage regulation circuitry.

2. Digital-Only Output: Applications currently using the analog output of the SCA1000-D10 must transition to SPI digital interface. Existing analog signal conditioning circuits will require replacement with SPI communication firmware.

3. Acceleration Range Selection: The ±1.5g selectable scale on the SCA3300-D01-1 provides the closest functional match to the ±1.7g specification. Applications requiring the exact 1.7g threshold must evaluate whether ±1.5g or ±3g modes meet performance requirements.

4. Compliance Status: The SCA3300-D01-1 is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The obsolete status of the SCA1000-D10 makes substitution necessary for new production and long-term supply assurance.

5. Tri-Axis Capability: The additional X-axis measurement on the SCA3300-D01-1 provides enhanced motion sensing capability without additional cost or board space.

Frequently Asked Questions (FAQ)

Q: Can the SCA3300-D01-1 directly replace the SCA1000-D10 without PCB modifications?

A: No. The SCA3300-D01-1 requires PCB-level changes: voltage supply modification (3V ~ 3.6V instead of 4.75V ~ 5.25V), removal of analog signal conditioning circuits, and implementation of SPI communication interface. Package form differences may also require footprint adjustment.

Q: What is the closest acceleration range match between these parts?

A: The SCA3300-D01-1 offers selectable acceleration ranges of ±1.5g, ±3g, and ±6g. The ±1.5g setting provides the closest functional match to the original ±1.7g specification. Applications must verify that ±1.5g sensitivity meets performance requirements.

Q: Is the SCA3300-D01-1 available in the same 12-SMD package?

A: No. The SCA3300-D01-1 uses a nonstandard package form, differing from the 12-SMD gull wing package of the SCA1000-D10. PCB footprint redesign is required.

Q: Can I use only the Y and Z axes of the SCA3300-D01-1 and ignore the X-axis?

A: Yes. The SCA3300-D01-1 provides tri-axis measurement capability, but firmware can be configured to use only Y and Z axis data, effectively matching the dual-axis configuration of the original part.

Q: What are the compliance differences between these parts?

A: The SCA1000-D10 is obsolete with no current compliance status. The SCA3300-D01-1 is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards required for new product designs and manufacturing.

Q: Does the SCA3300-D01-1 include a temperature sensor like the original part?

A: The provided specifications do not indicate a temperature sensor feature on the SCA3300-D01-1. Verify with the manufacturer datasheet if temperature measurement capability is required for your application.
