Panasonic DP2-40N Digital Pressure Sensor - Equivalent & Substitute Parts

Part Overview

The Panasonic DP2-40N is a digital pressure sensor designed for industrial automation applications, specifically configured for vacuum pressure measurement with NPN open collector output. This sensor features a vacuum operating range of -14.65PSI (-101kPa) and operates across a supply voltage range of 12V to 24V. The product is currently classified as obsolete, making identification of suitable substitute components essential for system maintenance and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete DP2-40N requires evaluation of the following critical parameters that determine functional equivalence:

Output Signal Compatibility: Both the main part and substitute must provide NPN open collector output to maintain compatibility with existing control circuits and signal processing equipment.

Supply Voltage Range: The substitute must operate within the 12V to 24V supply voltage specification to ensure direct integration into existing power distribution systems without additional conditioning or regulation.

Pressure Measurement Range: The substitute must accommodate the operating pressure specification of -14.65PSI (-101kPa) and maximum pressure rating of -71.07PSI (-490kPa) for vacuum applications.

Port Interface: The substitute must feature a threaded female port configuration compatible with standard industrial pneumatic connections.

Operating Temperature Range: The substitute must maintain functionality across the -10°C to 50°C operating temperature envelope.

Environmental Compliance: The substitute must meet RoHS compliance requirements and maintain MSL rating of 1 (Unlimited) for storage and handling compatibility.

The Panasonic DP-101-M is identified as a substitute component based on shared output type (NPN open collector), identical supply voltage range (12V ~ 24V), compatible operating temperature range (-10°C ~ 50°C), threaded female port configuration, and equivalent environmental compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The Panasonic DP-101-M is available as an active product with current manufacturing status, providing supply chain continuity for applications previously served by the obsolete DP2-40N. Both components share identical supply voltage specifications (12V ~ 24V), output signal type (NPN open collector), operating temperature range (-10°C ~ 50°C), and environmental compliance certifications (RoHS and MSL 1).

The DP-101-M maintains equivalent electrical interface characteristics and connector compatibility through threaded female port configuration. Both components meet ROHS3 compliance requirements and carry unlimited moisture sensitivity ratings, ensuring compatibility with standard industrial automation storage and handling protocols.

The primary design consideration involves pressure measurement type differentiation: the DP2-40N operates as a vacuum sensor with negative pressure range, while the DP-101-M functions as a vented gauge sensor with bidirectional pressure measurement capability. This distinction requires evaluation of the specific application pressure profile to determine functional suitability.

Frequently Asked Questions (FAQ)

Q: Can the DP-101-M directly replace the DP2-40N in existing installations?

A: Direct replacement requires verification that the application pressure profile is compatible with the DP-101-M's vented gauge measurement type. The DP2-40N measures vacuum (negative) pressure, while the DP-101-M measures gauge pressure (positive and negative relative to atmospheric). If the system requires vacuum measurement specifically, alternative components may be necessary.

Q: Are the electrical connectors compatible between these two sensors?

A: Both components feature NPN open collector output and identical 12V to 24V supply voltage specifications. Signal-level compatibility is maintained. Physical connector compatibility depends on the specific termination interface used in the existing installation.

Q: What is the difference between the port sizes on these two sensors?

A: The DP2-40N features a 1/8" (3.18mm) NPT female port, while the DP-101-M uses an M5 female port. Both are threaded configurations but require different adapter specifications for pneumatic line connection.

Q: Does the DP-101-M include a display like the DP2-40N?

A: The DP2-40N is packaged as a Module Box with Display, while the DP-101-M is packaged as a Module without integrated display. Display functionality must be evaluated separately if required for the application.

Q: Are both sensors RoHS compliant?

A: Yes. The DP2-40N meets RoHS Compliant specification, and the DP-101-M meets ROHS3 Compliant specification. Both satisfy current environmental compliance requirements for industrial automation applications.

Q: What is the inventory status for these components?

A: The DP2-40N (obsolete) has 836 pieces available as new original stock. The DP-101-M (active product) has 1037 pieces available as new original stock, providing greater long-term supply availability.
