DP2-42 Pressure Sensor Equivalent & Substitute Parts

Part Overview

The DP2-42 is a vented gauge pressure sensor manufactured by Panasonic Industrial Automation Sales, designed for industrial automation applications. It operates at 1 MPA (145.04 PSI) nominal pressure with analog voltage and NPN open collector output options. The product is currently obsolete, making identification of compatible substitute components essential for system maintenance and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

The DP-102-M qualifies as a substitute for the DP2-42 based on the following critical parameters:

Matching Parameters:

• Manufacturer: Panasonic Industrial Automation Sales (same source)
• Pressure Type: Vented Gauge (identical measurement principle)
• Voltage Supply: 12V ~ 24V (compatible power requirements)
• Port Style: Threaded (same mechanical interface type)
• Termination Style: Connector (same connection method)
• Operating Temperature: -10°C ~ 50°C (identical thermal range)
• Output Type: NPN - Open Collector (compatible signal output)
• RoHS Status: ROHS3 Compliant (meets regulatory requirements)
• ECCN: EAR99 (same export classification)

Functional Compatibility: The DP-102-M operates across an extended pressure range (-100 kPa to 1000 kPa) that encompasses the DP2-42 nominal operating point of 1000 kPa. The maximum pressure rating of 1500 kPa on the DP-102-M exceeds the DP2-42 maximum of 1470 kPa, providing equivalent or superior pressure handling capability.

Parameter Comparison

Engineering Selection Recommendations

The DP-102-M is an active product from the same manufacturer (Panasonic Industrial Automation Sales) and represents the current generation equivalent to the obsolete DP2-42. Selection of the DP-102-M is supported by:

• Active product status ensuring ongoing availability and supply chain continuity
• ROHS3 compliance, meeting current regulatory requirements
• Identical electrical and thermal operating parameters
• Equivalent or superior pressure handling specifications
• Compatible connector-based termination and threaded port interface
• Same export classification (EAR99)

The primary design consideration is port size: the DP2-42 uses Female 1/8" (3.18mm) BSPT, while the DP-102-M uses Female M5. Mechanical adapter solutions or port modification may be required depending on installation constraints.

Frequently Asked Questions (FAQ)

Q: Can the DP-102-M directly replace the DP2-42 without modification?

A: The DP-102-M provides equivalent electrical and functional performance. However, the port size differs (1/8" BSPT on DP2-42 versus M5 on DP-102-M), requiring mechanical adaptation or port modification for installation into existing manifolds or tubing systems.

Q: Are the output signals compatible between DP2-42 and DP-102-M?

A: Both sensors provide NPN open collector output compatible with industrial automation control systems. The DP2-42 also offers analog voltage output; verify that your system can operate with the DP-102-M's NPN open collector output alone.

Q: What is the pressure measurement range difference?

A: The DP2-42 operates at 1000 kPa nominal pressure. The DP-102-M operates across -100 kPa to 1000 kPa, providing extended range capability including vacuum measurement capability. Both sensors handle maximum pressures within 30 kPa of each other (1470 kPa vs. 1500 kPa).

Q: Are there compliance or certification differences?

A: The DP2-42 is RoHS Compliant. The DP-102-M is ROHS3 Compliant, meeting the current regulatory standard. Both carry EAR99 export classification.

Q: What packaging differences exist?

A: The DP2-42 is supplied in Module Box with Display packaging. The DP-102-M is supplied in Module Box packaging. Verify that display functionality, if required, is available through your system integration approach.
