SDP616 Equivalent & Substitute Parts

Part Overview

The SDP616 is a differential pressure sensor manufactured by Sensirion AG, designed for board mount applications with a barbed male port configuration (0.2" / 5.2mm tube, dual). This sensor operates at ±0.07PSI (±0.5kPa) differential pressure with 16-bit I2C output and temperature compensation. The SDP616 is classified as obsolete, making identification of active equivalent parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

The SDP810-500PA qualifies as a manufacturer-recommended substitute based on the following alignment criteria:

Matching Parameters:

• Differential pressure sensor type
• Identical pressure measurement range: ±0.07PSI (±0.5kPa)
• I2C digital output interface
• 16-bit output resolution
• ±3% accuracy specification
• Male barbed port configuration: 0.2" (5.2mm) tube, dual
• Temperature compensation feature
• ROHS3 compliance
• Same HTSUS classification (9026.20.4000)

Series Transition: The SDP810-500PA represents the active-production equivalent within Sensirion's SDP800 series, replacing the obsolete SDP600 series (SDP616). This transition maintains functional and electrical compatibility while providing improved supply availability and extended product lifecycle support.

Parameter Comparison

Engineering Selection Recommendations

The SDP810-500PA is the appropriate substitute for the obsolete SDP616 based on the following engineering criteria:

Product Lifecycle Status: The SDP616 is obsolete with no ongoing manufacturing support. The SDP810-500PA is in active production status, ensuring long-term component availability, supply chain stability, and manufacturer technical support.

Functional Equivalence: Both sensors maintain identical pressure measurement specifications (±0.07PSI / ±0.5kPa differential), I2C output protocol, 16-bit resolution, and ±3% accuracy. Port geometry and barbed connector configuration are identical, supporting direct mechanical integration.

Electrical Compatibility: The SDP810-500PA supply voltage range (3V ~ 5.5V) encompasses the SDP616 operating range (2.7V ~ 3.3V). Systems powered within the SDP616 specification will operate the SDP810-500PA without modification. The extended upper voltage limit provides additional design flexibility for new implementations.

Environmental Performance: The SDP810-500PA extends the upper operating temperature limit to 85°C (versus 80°C for SDP616), providing improved thermal margin in applications approaching the SDP616 specification boundary.

Regulatory Compliance: Both components maintain ROHS3 compliance and identical HTSUS classification, ensuring regulatory continuity for existing product certifications and supply chain documentation.

Frequently Asked Questions (FAQ)

Q: Can the SDP810-500PA directly replace the SDP616 in existing designs?

A: Yes. The SDP810-500PA maintains identical pressure measurement range, I2C protocol, output resolution, accuracy, and port configuration. Existing PCB layouts, firmware implementations, and mechanical assemblies require no modification. The SDP810-500PA supply voltage range (3V ~ 5.5V) is compatible with SDP616 power supplies operating at 2.7V ~ 3.3V.

Q: What are the key differences between SDP616 and SDP810-500PA?

A: The primary differences are product status (obsolete versus active production), series designation (SDP600 versus SDP800), supply voltage range (2.7V ~ 3.3V versus 3V ~ 5.5V), and maximum operating temperature (80°C versus 85°C). All functional pressure measurement parameters remain identical.

Q: Are there any firmware or software changes required when switching from SDP616 to SDP810-500PA?

A: No. Both sensors use identical I2C communication protocol and 16-bit output format. Existing firmware and software implementations require no modification.

Q: What is the packaging difference between these two parts?

A: The SDP616 is specified as 4-SIP Module with PC Pin termination. The SDP810-500PA is specified as Module with standard termination. Both are module-based form factors compatible with through-hole mounting applications. Verify mechanical fit with your specific PCB layout.

Q: Is the SDP810-500PA available in the same quantities as the SDP616?

A: The SDP810-500PA is in active production with significantly higher inventory availability (24,838 pieces in stock versus 683 pieces for the obsolete SDP616). This ensures reliable supply for both replacement and new production requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both the SDP616 and SDP810-500PA are ROHS3 compliant and maintain identical regulatory classification for supply chain and certification purposes.
