DP2-21Z Pressure Sensor Equivalent & Substitute Parts

Part Overview

The DP2-21Z is a vented gauge pressure sensor manufactured by Panasonic Industrial Automation Sales, designed for industrial automation applications. This sensor operates at 100 kPa (14.5 PSI) with analog voltage and NPN open collector output capabilities. The product is currently obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and component sourcing in ongoing industrial applications.

Key Parameters

Substitute Part Grouping Explanation

The E8F2-D10C from Omron Automation and Safety qualifies as a functional substitute based on the following critical parameters:

Matching Parameters:

• Pressure Type: Vented Gauge (identical)
• Output Type: NPN - Open Collector (identical)
• Voltage Supply: 12V ~ 24V (identical)
• Port Style: Threaded (identical)
• Port Size: Female - 1/8" (3.18mm) BSPT available (compatible)
• RoHS Status: RoHS Compliant (identical)
• Application Category: Industrial Automation (identical)

Allowable Differences:

• Operating Pressure: E8F2-D10C operates at 145 PSI (999.74 kPa), which exceeds the DP2-21Z operating pressure of 100 kPa. Higher pressure rating allows operation within the original sensor's range.
• Output Signal: E8F2-D10C provides 1V ~ 5V analog output, compatible with NPN open collector systems.
• Accuracy: E8F2-D10C specifies ±3% accuracy, providing defined performance metrics.
• Operating Temperature: E8F2-D10C range of 0°C ~ 55°C encompasses the DP2-21Z range of -10°C ~ 50°C with partial overlap.
• Termination Style: E8F2-D10C uses cable termination versus connector termination on DP2-21Z; both are standard industrial configurations.

Parameter Comparison

Engineering Selection Recommendations

The E8F2-D10C is an active product from Omron Automation and Safety and serves as a functional equivalent for DP2-21Z applications. Both components maintain RoHS compliance and operate within the 12V ~ 24V supply range required by industrial automation systems.

Selection of E8F2-D10C is appropriate when:

• Operating pressure does not exceed 145 PSI (999.74 kPa)
• Operating temperature range remains between 0°C and 55°C
• NPN open collector output is compatible with existing control circuitry
• Cable termination can be integrated into the system design, or adapter solutions are available
• Vented gauge pressure measurement is the required sensing mode

The higher pressure rating of E8F2-D10C (145 PSI versus 100 kPa operating pressure) provides operational margin within the DP2-21Z application envelope. The specified ±3% accuracy of E8F2-D10C establishes defined performance characteristics for systems where the original DP2-21Z accuracy was not documented.

Frequently Asked Questions (FAQ)

Q: Can the E8F2-D10C directly replace the DP2-21Z in all applications?

A: The E8F2-D10C is functionally equivalent for applications operating between 0°C and 55°C. If the original system operates below 0°C, the E8F2-D10C temperature range does not extend to -10°C. Termination style differs; the E8F2-D10C uses cable termination while the DP2-21Z uses connector termination, requiring interface consideration.

Q: What are the key compatibility parameters?

A: Critical matching parameters are pressure type (vented gauge), output type (NPN open collector), supply voltage (12V ~ 24V), and port style (threaded). The E8F2-D10C meets all these requirements. Port size compatibility is confirmed for the 1/8" BSPT configuration.

Q: Does the higher pressure rating of E8F2-D10C affect compatibility?

A: No. The E8F2-D10C maximum pressure rating of 145 PSI exceeds the DP2-21Z operating pressure of 100 kPa (14.5 PSI). A higher pressure rating does not compromise operation at lower pressures and provides additional safety margin.

Q: Are there temperature range limitations?

A: The E8F2-D10C operates from 0°C to 55°C. The DP2-21Z operates from -10°C to 50°C. If the application requires operation below 0°C, the E8F2-D10C does not meet this requirement.

Q: What is the difference between connector and cable termination?

A: The DP2-21Z uses connector termination for plug-and-socket connection. The E8F2-D10C uses cable termination with direct wire leads. System integration requires appropriate wiring or adapter solutions.

Q: Are both components RoHS compliant?

A: Yes. Both the DP2-21Z and E8F2-D10C are RoHS compliant, meeting environmental and regulatory requirements for industrial automation applications.
