Substitute Part Grouping Explanation

The SFM3003-300-CE is identified as the manufacturer-recommended substitute for the SFM3000-200. Substitution eligibility is determined by the following parameters:

Common Substitution Criteria:

• Manufacturer: Both parts are manufactured by Sensirion AG
• Flow Sensor Type: Both are gas flow sensors
• Port Size: Both feature Male, 0.8661" (22mm) connectors
• Communication Interface: Both support digital communication protocols
• Compliance: Both are ROHS3 Compliant and REACH Unaffected
• Voltage Compatibility: SFM3003-300-CE operates at 2.7V ~ 5.5V, which encompasses the SFM3000-200's 5V requirement

Key Differences Affecting Substitution:

• Sensing Range: SFM3000-200 operates 0 ~ 1.25 mbar; SFM3003-300-CE operates -150 ~ +300 SLPM (different measurement units and ranges)
• Material - Body: SFM3000-200 uses Plastic; SFM3003-300-CE uses Steel
• Operating Temperature: SFM3000-200 operates -20°C ~ 80°C; SFM3003-300-CE operates -20°C ~ 85°C
• Product Status: SFM3000-200 is "Not For New Designs"; SFM3003-300-CE is "Active"

Parameter Comparison

Engineering Selection Recommendations

The SFM3003-300-CE is the manufacturer-recommended substitute for the SFM3000-200. Selection of this substitute is supported by the following factors:

• Active Product Status: The SFM3003-300-CE is classified as "Active," ensuring ongoing manufacturer support, availability, and compliance updates, whereas the SFM3000-200 is "Not For New Designs."
• Regulatory Compliance: Both parts maintain ROHS3 Compliance and REACH Unaffected status, meeting current environmental and regulatory requirements.
• Voltage Compatibility: The SFM3003-300-CE's input voltage range of 2.7V ~ 5.5V is compatible with the SFM3000-200's 5V requirement.
• Mechanical Compatibility: Identical port size (Male, 0.8661" / 22mm) ensures direct mechanical fit in existing installations.
• Manufacturer Endorsement: Sensirion AG explicitly identifies this part as the recommended substitute.

Applications requiring the SFM3000-200 should transition to the SFM3003-300-CE for new designs and ongoing production. Existing installations using the SFM3000-200 may continue operation; however, long-term availability of the legacy part cannot be guaranteed.

Frequently Asked Questions (FAQ)

Q: Can the SFM3003-300-CE directly replace the SFM3000-200 in existing designs?

A: Mechanical and electrical compatibility is confirmed through identical port sizes and compatible voltage ranges. However, the sensing range differs significantly (0 ~ 1.25 mbar versus -150 ~ +300 SLPM), and the body material changes from Plastic to Steel. Application-specific validation is required to confirm functional equivalence for your measurement requirements.

Q: What is the difference between the sensing ranges of these two parts?

A: The SFM3000-200 operates within 0 ~ 1.25 mbar, while the SFM3003-300-CE operates within -150 ~ +300 SLPM. These represent different measurement units and pressure/flow ranges. Confirm that the SFM3003-300-CE's range accommodates your application's requirements.

Q: Are there any temperature operating differences?

A: The SFM3000-200 operates from -20°C to 80°C, while the SFM3003-300-CE operates from -20°C to 85°C. The SFM3003-300-CE provides a 5°C extended upper temperature limit.

Q: Does the material change from Plastic to Steel affect performance?

A: The body material change from Plastic to Steel may affect thermal properties, durability, and environmental resistance. Evaluate whether the Steel construction is compatible with your application's environmental conditions and mechanical requirements.

Q: Are both parts available in the same packaging?

A: Yes, both the SFM3000-200 and SFM3003-300-CE are supplied in Tray packaging, ensuring consistent handling and storage requirements.

Q: What is the communication interface for the SFM3003-300-CE?

A: The SFM3003-300-CE supports digital communication; however, the specific protocol designation differs from the SFM3000-200's I2C interface. Verify protocol compatibility with your system architecture before implementation.
