SDP1000-L05 Equivalent & Substitute Parts

Part Overview

The SDP1000-L05 is a differential pressure sensor manufactured by Sensirion AG, designed for board mount applications with a measurement range of -0.001PSI to 0.013PSI (-0.005kPa to 0.125kPa). The sensor features analog voltage output (0.25V to 4V), temperature compensation, and a barbed male connection for 0.2" (5.2mm) tubing. However, this part is classified as Not For New Designs, making identification of functionally equivalent alternatives essential for ongoing system support and new product development initiatives.

Key Parameters

Substitute Part Grouping Explanation

The SDP816-500PA qualifies as a substitute for the SDP1000-L05 based on the following critical parameters:

Mechanical Compatibility: Both sensors feature identical port configurations (Male - 0.2" (5.2mm) Tube, Dual with Barbed style), enabling direct physical integration into existing tubing systems without adapter modifications.

Functional Characteristics: Both sensors provide differential pressure measurement with analog voltage output, temperature compensation, and identical maximum pressure ratings (14.5PSI / 100kPa). Both are classified as board mount applications and packaged as modules.

Electrical Interface: Both sensors operate within overlapping supply voltage ranges and produce analog voltage outputs suitable for standard signal conditioning circuits.

Compliance & Certification: Both parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment for industrial and commercial applications.

Key Substitution Constraints: The SDP816-500PA operates at a higher pressure sensitivity range (-0.07PSI ~ 0.07PSI versus -0.001PSI ~ 0.013PSI) and exhibits reduced accuracy (±3% versus ±0.3%). These differences require application-level validation to confirm suitability for specific pressure measurement requirements.

Parameter Comparison

Engineering Selection Recommendations

The SDP816-500PA represents the primary substitute option for the SDP1000-L05, supported by active product status and extended operational temperature range (-20°C to 85°C versus -10°C to 60°C). Both components maintain equivalent regulatory compliance through ROHS3 certification and REACH Unaffected designation.

Selection between these components depends on application-specific pressure measurement requirements. The SDP1000-L05 provides superior accuracy (±0.3%) and operates within a narrower, lower-range pressure band suitable for ultra-low differential pressure applications. The SDP816-500PA accommodates broader pressure ranges and wider supply voltage tolerance (3V to 5.5V), offering greater flexibility for systems with variable power supply conditions.

The SDP816-500PA's active product status ensures long-term availability and manufacturing support, whereas the SDP1000-L05's Not For New Designs classification indicates limited future availability. For new system development or long-term production planning, the SDP816-500PA is the preferred selection.

Frequently Asked Questions (FAQ)

Q: Can the SDP816-500PA directly replace the SDP1000-L05 in existing installations?

A: Physical and electrical compatibility is confirmed through identical port configurations (Male - 0.2" barbed tubing) and compatible analog voltage output interfaces. However, the SDP816-500PA operates at a higher pressure sensitivity range (-0.07PSI to 0.07PSI) with reduced accuracy (±3% versus ±0.3%). Substitution validity depends on whether the application's pressure measurement requirements fall within the SDP816-500PA's operating range and can tolerate the reduced accuracy specification.

Q: What are the key differences in electrical interface between these sensors?

A: Both sensors provide analog voltage output with overlapping supply voltage ranges. The SDP1000-L05 requires 4.75V to 5.25V supply, while the SDP816-500PA accepts 3V to 5.5V. Output voltage ranges differ slightly (0.25V to 4V versus 0.5V to 4.5V), requiring signal conditioning circuit validation to confirm compatibility with downstream analog-to-digital conversion stages.

Q: Why does the SDP816-500PA have lower accuracy than the SDP1000-L05?

A: The SDP816-500PA is designed for broader pressure measurement applications with a five-fold larger operating range (-0.07PSI to 0.07PSI). This expanded measurement span inherently results in reduced accuracy specification (±3%) compared to the SDP1000-L05's narrower, specialized range (±0.001PSI to 0.013PSI) with ±0.3% accuracy. Accuracy specifications reflect the sensor's design optimization for its intended pressure measurement band.

Q: Are there packaging or moisture sensitivity considerations for substitution?

A: Both components are supplied in Module packaging with identical mechanical form factors. The SDP1000-L05 lists Moisture Sensitivity Level as Not Applicable, while the SDP816-500PA specifies MSL 1 (Unlimited). This difference does not impact substitution feasibility for standard industrial applications but may require consideration in high-humidity storage or tropical deployment scenarios.

Q: What is the significance of the SDP1000-L05's Not For New Designs status?

A: This classification indicates that Sensirion AG is not recommending this component for new product development initiatives. While existing inventory remains available (954 pieces in stock), the manufacturer is directing customers toward alternative solutions for new designs. The SDP816-500PA's Active status confirms ongoing manufacturing support and long-term availability, making it the recommended choice for systems requiring extended production lifecycles.
