DP2-20-C5 Equivalent & Substitute Parts

Part Overview

The DP2-20-C5 is a vacuum pressure sensor manufactured by Panasonic Industrial Automation Sales, designed for industrial automation applications. This sensor operates in the negative pressure range (-101 kPa gauge) and provides analog voltage output through NPN open collector configuration. The product is currently obsolete, making equivalent substitute parts necessary for system maintenance, repair, and component sourcing in ongoing industrial applications.

Substitute Part Grouping Explanation

Substitution of the DP2-20-C5 is determined by the following critical parameters:

Pressure Type & Operating Range: The DP2-20-C5 operates as a vacuum (negative gauge) sensor at -101 kPa. Substitute parts must accommodate negative pressure measurement within compatible ranges.
Output Configuration: NPN open collector output type must be maintained for circuit compatibility.
Supply Voltage: 12V ~ 24V supply voltage range must be supported.
Port Interface: Threaded female port connection must be compatible with existing system plumbing.
Operating Temperature: -10°C ~ 50°C operating range must be met or exceeded.
Compliance & Status: Active product status with current RoHS certification ensures ongoing availability and regulatory compliance.

The DP-101-M from the DP-100 series is identified as a substitute based on matching output type, supply voltage, operating temperature range, port style, and manufacturer continuity within the Panasonic Industrial Automation Sales product line.

Engineering Selection Recommendations

The DP-101-M serves as an active substitute for the obsolete DP2-20-C5 based on the following engineering criteria:

Product Availability: The DP-101-M is an active product with current inventory (1037 pcs), whereas the DP2-20-C5 is obsolete. This ensures long-term component sourcing and supply chain continuity.
Regulatory Compliance: Both parts meet RoHS requirements. The DP-101-M carries ROHS3 certification, representing current compliance standards.
Electrical Compatibility: Identical supply voltage range (12V ~ 24V) and NPN open collector output configuration ensure direct integration into existing control circuits.
Environmental Operating Range: Both sensors operate across -10°C ~ 50°C, maintaining thermal performance consistency.
Mechanical Interface: Both employ threaded female connectors for system integration, though port sizes differ (1/8" BSPT vs. M5).

Selection of the DP-101-M requires verification that the M5 port interface is compatible with existing system plumbing connections. Additionally, the shift from vacuum pressure measurement to vented gauge measurement must be evaluated against application requirements.

Frequently Asked Questions (FAQ)

Q: Can the DP-101-M directly replace the DP2-20-C5 without modifications?

A: Electrical and thermal compatibility is established through matching supply voltage, output type, and operating temperature range. However, the port size difference (1/8" BSPT vs. M5) and pressure measurement type difference (vacuum vs. vented gauge) require mechanical and functional assessment before installation.

Q: What is the primary difference between the DP2-20-C5 and DP-101-M?

A: The DP2-20-C5 measures vacuum (negative gauge) pressure at -101 kPa, while the DP-101-M measures vented gauge pressure at ±100 kPa. This functional difference affects application suitability and must be evaluated against system requirements.

Q: Are both sensors compatible with 24V DC supply systems?

A: Yes. Both the DP2-20-C5 and DP-101-M support 12V ~ 24V supply voltage range, making them compatible with standard industrial control voltage systems.

Q: What connector type is used on both sensors?

A: Both sensors employ connector-based termination style. The specific connector type and pin configuration should be verified against system documentation for proper integration.

Q: Is the DP-101-M suitable for applications requiring vacuum pressure measurement?

A: The DP-101-M is configured for vented gauge pressure measurement, not vacuum measurement. Applications requiring negative pressure sensing should confirm functional compatibility before substitution.

Q: What is the inventory status of these parts?

A: The DP2-20-C5 has 1060 pcs in stock but is obsolete. The DP-101-M has 1037 pcs in stock and is an active product, ensuring ongoing availability.
