DP3-80 Pressure Sensor Equivalent & Substitute Parts

Part Overview

The DP3-80 is a vacuum pressure sensor manufactured by Panasonic Industrial Automation Sales, designed for industrial automation applications. This sensor measures gauge pressure in the vacuum range with NPN open collector output and operates across a 12V to 24V supply voltage. The product is currently obsolete, making equivalent substitute parts necessary for system maintenance, repair, and new installations where legacy component compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DP3-80 is determined by the following critical parameters that must align between the main part and substitute:

• Pressure Type: Both must measure vacuum pressure
• Operating Pressure Range: Substitute must cover -14.65 PSI (-101 kPa) minimum
• Output Type: NPN open collector output is required for signal compatibility
• Voltage Supply: 12V to 24V supply voltage compatibility
• Port Configuration: Female M5 threaded port for mechanical fit
• Maximum Pressure Rating: Substitute must withstand at least -71.07 PSI (-490 kPa)
• Operating Temperature Range: Substitute must function within -10°C to 50°C
• Termination: Cable termination for direct integration

The E8F2-AN0C from Omron Automation and Safety meets these substitution criteria across all critical parameters.

Parameter Comparison

Engineering Selection Recommendations

The E8F2-AN0C is a direct functional substitute for the obsolete DP3-80 pressure sensor. Both components are RoHS compliant and share identical core specifications for pressure measurement, output signaling, and supply voltage requirements. The substitute maintains compatibility with existing M5 threaded port installations and cable termination configurations.

The E8F2-AN0C is currently in active production status, ensuring availability for immediate procurement and future supply chain continuity. This contrasts with the DP3-80, which is obsolete and subject to inventory depletion.

Minor parameter variations exist: the E8F2-AN0C specifies a 1 V to 5 V output range and ±3% accuracy, whereas the DP3-80 does not provide these specifications. The E8F2-AN0C's maximum pressure rating of -58.02 PSI (-400 kPa) is lower than the DP3-80's -71.07 PSI (-490 kPa), but remains adequate for the specified operating pressure of -14.65 PSI (-101 kPa). The E8F2-AN0C's operating temperature range begins at 0°C rather than -10°C; applications requiring operation below 0°C should be evaluated against actual system requirements.

Frequently Asked Questions (FAQ)

Q: Can the E8F2-AN0C directly replace the DP3-80 in existing installations?

A: Yes. Both sensors share identical pressure type (vacuum), operating pressure (-14.65 PSI / -101 kPa), output type (NPN open collector), supply voltage (12V to 24V), port configuration (Female M5 threaded), and termination style (cable). Mechanical and electrical integration is compatible.

Q: What is the difference in maximum pressure rating between these sensors?

A: The DP3-80 is rated to -71.07 PSI (-490 kPa) maximum, while the E8F2-AN0C is rated to -58.02 PSI (-400 kPa) maximum. For applications operating at the specified -14.65 PSI (-101 kPa) pressure, both ratings provide adequate safety margin. Applications approaching -60 PSI should verify the E8F2-AN0C's suitability.

Q: Does the E8F2-AN0C work in the same temperature range as the DP3-80?

A: The E8F2-AN0C operates from 0°C to 55°C, compared to the DP3-80's -10°C to 50°C range. The substitute covers the primary operating window but does not extend to -10°C. Systems requiring operation below 0°C must confirm compatibility with actual environmental conditions.

Q: Why does the E8F2-AN0C specify output voltage and accuracy while the DP3-80 does not?

A: The DP3-80 datasheet does not provide these specifications. The E8F2-AN0C provides defined output characteristics (1 V to 5 V) and accuracy (±3%), which are standard for modern NPN open collector pressure sensors. These specifications enable more precise system design and signal conditioning.

Q: Are both sensors RoHS compliant?

A: Yes. Both the DP3-80 and E8F2-AN0C are RoHS compliant, meeting environmental and regulatory requirements for industrial automation applications.

Q: What is the packaging difference between these parts?

A: The DP3-80 is supplied in a Module Box with Display. The E8F2-AN0C is supplied in Bulk packaging. Both are delivered as complete sensor units suitable for direct installation.
