DP4-50P Vacuum Pressure Sensor - Equivalent & Substitute Parts

Part Overview

The DP4-50P is a vacuum pressure sensor manufactured by Panasonic Industrial Automation Sales, designed for industrial automation applications requiring vacuum pressure measurement in the 0 to -101.3 kPa range. This sensor features PNP open collector output and operates across 12V to 24V supply voltage with a threaded female M5 port connection.

The DP4-50P is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system functionality and ensure continued availability for replacement, repair, and new installations where this sensor specification is required.

Key Parameters

Substitute Part Grouping Explanation

The E8F2-AN0B from Omron Automation and Safety qualifies as a substitute for the DP4-50P based on the following critical parameters:

Matching Parameters (Substitution Basis):

• Pressure Type: Both measure vacuum pressure
• Operating Pressure Range: Both operate at -14.65 PSI (-101 kPa)
• Output Type: Both feature PNP - Open Collector output
• Voltage Supply: Both operate on 12V ~ 24V
• Port Style: Both use threaded connections
• RoHS Compliance: Both are RoHS Compliant
• Moisture Sensitivity Level: Both rated at MSL 1 (Unlimited)

Differences to Consider:

• Port Size: DP4-50P uses Female M5; E8F2-AN0B offers Female M5 and Male 1/8" BSPT options
• Output Signal: DP4-50P provides no specified output voltage; E8F2-AN0B provides 1V ~ 5V output
• Accuracy: DP4-50P accuracy not specified; E8F2-AN0B provides ±3% accuracy
• Maximum Pressure: DP4-50P rated to -71.07 PSI; E8F2-AN0B rated to -58.02 PSI
• Operating Temperature: DP4-50P operates 0°C ~ 50°C; E8F2-AN0B operates 0°C ~ 55°C
• Termination Style: DP4-50P uses Connector; E8F2-AN0B uses Cable

Parameter Comparison

Engineering Selection Recommendations

The E8F2-AN0B is an active product from Omron Automation and Safety and serves as a functional substitute for the obsolete DP4-50P. Both sensors meet identical vacuum pressure measurement requirements, operate within the same supply voltage range, and share PNP open collector output architecture.

Selection of the E8F2-AN0B over the DP4-50P is supported by:

• Active product status ensuring ongoing availability and supply chain reliability
• RoHS compliance matching the original specification
• Identical operating pressure range and output type
• Expanded operating temperature range (0°C ~ 55°C vs. 0°C ~ 50°C)
• Specified output signal (1V ~ 5V) and accuracy (±3%) providing measurable performance characteristics

Integration considerations include port connection compatibility (M5 female available on E8F2-AN0B) and termination style transition from connector to cable, which may require interface adaptation depending on system design.

Frequently Asked Questions (FAQ)

Q: Can the E8F2-AN0B directly replace the DP4-50P without modifications?

A: The E8F2-AN0B matches the DP4-50P on core functional parameters: vacuum pressure measurement, operating pressure range, PNP output type, and supply voltage. However, the termination style differs (connector vs. cable), requiring interface adaptation. Port size compatibility exists with the M5 female option on the E8F2-AN0B.

Q: What are the critical parameters for substitution between these sensors?

A: Substitution is valid when the following parameters align: pressure type (vacuum), operating pressure range (-101 kPa), output type (PNP - Open Collector), supply voltage (12V ~ 24V), and port style (threaded). These parameters define functional equivalence for industrial automation applications.

Q: Does the E8F2-AN0B have a lower maximum pressure rating than the DP4-50P?

A: Yes. The DP4-50P is rated to -71.07 PSI (-490 kPa) maximum pressure, while the E8F2-AN0B is rated to -58.02 PSI (-400 kPa). Applications requiring operation beyond -400 kPa must account for this difference.

Q: Are both sensors RoHS compliant?

A: Yes. Both the DP4-50P and E8F2-AN0B are RoHS Compliant with MSL 1 (Unlimited) moisture sensitivity level.

Q: What is the difference in operating temperature range?

A: The DP4-50P operates from 0°C to 50°C, while the E8F2-AN0B operates from 0°C to 55°C. The E8F2-AN0B provides a 5°C extended upper temperature range.

Q: Does the E8F2-AN0B provide output signal specifications?

A: Yes. The E8F2-AN0B provides a 1V ~ 5V output signal with ±3% accuracy. The DP4-50P does not specify output voltage or accuracy characteristics.
