SDP1000-R Equivalent & Substitute Parts

Part Overview

The SDP1000-R is a differential pressure sensor manufactured by Sensirion AG, designed for board mount applications with a measurement range of -0.003PSI to 0.072PSI (-0.02kPa to 0.5kPa). The sensor features analog voltage output (0.25V to 4V), temperature compensation, and barbed male connectors for 0.2" (5.2mm) tubing. The SDP1000-R is classified as obsolete, necessitating identification of equivalent substitute components for ongoing system support and new design considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SDP1000-R are identified based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Pressure measurement range compatibility (-0.003PSI ~ 0.072PSI)
• Analog voltage output type (0.25V ~ 4V)
• Supply voltage compatibility (4.75V ~ 5.25V nominal)
• Port configuration (Male - 0.2" barbed connectors, dual)
• Temperature compensation feature
• Module package type
• Differential pressure sensing capability

Identified Substitute Parts:

SDP1000-L (Direct Manufacturer Substitute): Maintains identical pressure range, output characteristics, and mechanical interface. Differs in packaging (Tray vs. Module designation) and accuracy specification (±0.2% vs. ±0.3%). Product status is "Not For New Designs."

SDP1108-R (Manufacturer Recommended Substitute): Provides equivalent pressure measurement capability at 0.07PSI (0.5kPa) nominal, matching the upper operating range of the SDP1000-R. Maintains identical output voltage range, port configuration, and temperature compensation. Extends operating temperature range to -40°C ~ 80°C and supply voltage to 5V nominal. Accuracy specification is ±0.4%. Product status is "Not For New Designs."

Parameter Comparison

Engineering Selection Recommendations

SDP1000-L Selection Criteria: The SDP1000-L is a direct equivalent within the SDP1000 series, maintaining identical pressure measurement specifications and mechanical interfaces. This part is suitable for applications requiring the exact -0.003PSI to 0.072PSI range with no temperature extremes beyond -10°C to 60°C. The improved accuracy specification (±0.2%) provides enhanced measurement precision compared to the original SDP1000-R. Both parts carry ROHS3 compliance and equivalent regulatory status. The SDP1000-L is classified as "Not For New Designs," indicating limited long-term availability.

SDP1108-R Selection Criteria: The SDP1108-R is the manufacturer-recommended substitute, offering extended operating temperature range (-40°C to 80°C) suitable for applications with broader environmental requirements. The nominal pressure specification of 0.07PSI (0.5kPa) aligns with the upper measurement boundary of the SDP1000-R, ensuring compatibility for systems operating near maximum pressure thresholds. The SDP1108-R maintains identical output voltage characteristics, port configuration, and temperature compensation features. Supply voltage specification is 5V nominal, which falls within the SDP1000-R tolerance band. Accuracy specification is ±0.4%, representing a trade-off for extended temperature performance. This part also carries ROHS3 compliance and is classified as "Not For New Designs."

Frequently Asked Questions (FAQ)

Q: Can SDP1000-L be used as a direct replacement for SDP1000-R?

A: Yes. Both parts operate within the identical pressure range (-0.003PSI to 0.072PSI), provide 0.25V to 4V analog output, and feature barbed male connectors for 0.2" tubing. The primary difference is packaging designation and accuracy specification (±0.2% vs. ±0.3%). Electrical and mechanical interfaces are equivalent.

Q: What is the key difference between SDP1000-L and SDP1108-R?

A: The SDP1000-L maintains the exact pressure range of the original SDP1000-R (-0.003PSI to 0.072PSI). The SDP1108-R specifies a nominal pressure of 0.07PSI (0.5kPa), representing the upper measurement boundary. The SDP1108-R extends operating temperature range to -40°C to 80°C, compared to -10°C to 60°C for both SDP1000-R and SDP1000-L.

Q: Are all three parts ROHS3 compliant?

A: Yes. SDP1000-R, SDP1000-L, and SDP1108-R all carry ROHS3 compliance certification.

Q: Which substitute is recommended for applications with extreme temperature requirements?

A: The SDP1108-R is suitable for applications requiring operation beyond -10°C to 60°C, as it supports -40°C to 80°C operating range. The SDP1000-L maintains the original temperature specification of -10°C to 60°C.

Q: Do the substitute parts require different supply voltage?

A: The SDP1000-L operates on 4.75V to 5.25V, identical to the SDP1000-R. The SDP1108-R specifies 5V nominal supply voltage, which falls within the SDP1000-R tolerance band and is compatible with standard 5V power supplies.

Q: Are there any accuracy differences between the parts?

A: Yes. SDP1000-R specifies ±0.3% accuracy, SDP1000-L specifies ±0.2% (improved), and SDP1108-R specifies ±0.4%. Applications requiring the highest precision should prioritize SDP1000-L.

Q: Can these parts be used interchangeably in existing designs?

A: Mechanical and electrical interfaces are compatible. However, accuracy and temperature range specifications differ. System validation is necessary to confirm performance requirements are met by the selected substitute.
