Key Parameters

Substitute Part Grouping Explanation

The DP-101-M has been identified as a substitute for the DP2-20Z based on the following critical parameters:

Matching Parameters:

• Voltage supply range: 12V ~ 24V (identical)
• Output type: NPN - Open Collector (identical)
• Operating temperature range: -10°C ~ 50°C (identical)
• Port style: Threaded connector termination (identical)
• Manufacturer: Panasonic Industrial Automation Sales (identical)
• RoHS compliance: Both compliant (DP2-20Z: RoHS Compliant; DP-101-M: ROHS3 Compliant)

Functional Differences: The DP-101-M operates as a vented gauge pressure sensor with ±14.5 PSI (±100 kPa) operating pressure and ±72.52 PSI (±500 kPa) maximum pressure, whereas the DP2-20Z is a vacuum sensor. The DP-101-M represents an active product from the DP-100 series, ensuring ongoing availability and support.

Parameter Comparison

Engineering Selection Recommendations

The DP-101-M is suitable as a substitute for the DP2-20Z in applications where the pressure measurement range and type can be adapted to vented gauge operation. Both sensors maintain identical supply voltage specifications (12V ~ 24V), output type (NPN - Open Collector), and operating temperature range (-10°C ~ 50°C), ensuring electrical compatibility in control circuits.

The DP-101-M carries active product status with ROHS3 compliance, providing superior long-term availability compared to the obsolete DP2-20Z. Port interface differences (1/8" BSPT versus M5) require mechanical adapter consideration during integration.

Frequently Asked Questions (FAQ)

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

A: Electrical compatibility is maintained through identical voltage supply ranges and output types. However, the pressure measurement principle differs: DP2-20Z measures vacuum pressure, while DP-101-M measures vented gauge pressure. Application-specific pressure range requirements must be evaluated before substitution.

Q: What are the port interface differences between these sensors?

A: The DP2-20Z uses a Female 1/8" (3.18mm) BSPT threaded port, while the DP-101-M uses a Female M5 threaded port. Mechanical adapters or port modifications are necessary for physical installation compatibility.

Q: Are both sensors RoHS compliant?

A: Yes. The DP2-20Z is RoHS Compliant, and the DP-101-M is ROHS3 Compliant. Both meet environmental compliance requirements for industrial automation applications.

Q: Why is the DP2-20Z listed as obsolete?

A: The DP2-20Z has reached end-of-life status. The DP-101-M from the active DP-100 series represents Panasonic's current pressure sensor offering for similar industrial automation applications.

Q: What is the maximum pressure rating difference between these sensors?

A: The DP2-20Z maximum pressure is -71.07 PSI (-490 kPa) in the vacuum range, while the DP-101-M maximum pressure is ±72.52 PSI (±500 kPa) in the gauge pressure range. These represent equivalent absolute pressure handling capabilities within their respective measurement types.
