Key Parameters

Substitute Part Grouping Explanation

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

• Output Type: Both parts must provide NPN open collector output for direct circuit compatibility
• Voltage Supply Range: Compatible parts must operate within 12V to 24V supply voltage
• Operating Temperature Range: Substitute must maintain -10°C to 50°C operational capability
• Port Configuration: Threaded female connector interface for pneumatic coupling
• Pressure Measurement Type: Vacuum or gauge pressure measurement capability
• Regulatory Compliance: RoHS compliance status for environmental and procurement standards

The DP-101-M qualifies as a substitute based on matching output type, voltage supply range, operating temperature, threaded port style, and RoHS compliance. Differences in pressure type (vented gauge versus vacuum) and port size (M5 versus 1/8" BSPT) represent design variations that may require mechanical interface adaptation.

Parameter Comparison

Engineering Selection Recommendations

The DP-101-M is available as an active product with current manufacturing status, whereas the DP2-20 is obsolete. Both components share identical electrical interface specifications (NPN open collector output, 12V to 24V supply voltage, -10°C to 50°C operating temperature range) and equivalent moisture sensitivity ratings.

Selection of the DP-101-M as a replacement requires evaluation of pressure measurement requirements. The DP2-20 measures vacuum pressure, while the DP-101-M measures vented gauge pressure. These represent different measurement principles and may not be interchangeable in all applications. Additionally, port size differences (1/8" BSPT versus M5) necessitate mechanical interface adaptation through appropriate adapters or manifold modifications.

Both components meet RoHS compliance requirements, with the DP-101-M meeting the more recent ROHS3 standard. Procurement of the DP-101-M ensures access to active manufacturing support and supply chain availability.

Frequently Asked Questions (FAQ)

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

A: Direct replacement requires verification of pressure measurement type compatibility. The DP2-20 measures vacuum pressure while the DP-101-M measures vented gauge pressure. Port size differences (1/8" BSPT versus M5) require mechanical interface adaptation.

Q: Are the electrical outputs compatible between these parts?

A: Yes. Both components provide NPN open collector output and operate within the identical 12V to 24V supply voltage range, ensuring circuit-level compatibility.

Q: What is the significance of the pressure type difference?

A: Vacuum pressure sensors measure negative gauge pressure relative to atmospheric pressure. Vented gauge pressure sensors measure positive or negative pressure relative to atmospheric pressure. Application requirements determine which measurement type is appropriate.

Q: Do both parts meet current environmental compliance standards?

A: Yes. The DP2-20 is RoHS Compliant, and the DP-101-M meets ROHS3 Compliant standards. Both components satisfy current environmental and procurement requirements.

Q: What packaging differences exist between these components?

A: The DP2-20 is supplied in a Module Box with Display, while the DP-101-M is supplied in a Module package. Packaging differences do not affect electrical or functional performance.

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

A: The DP-101-M is designed for vented gauge pressure measurement. Applications requiring vacuum pressure measurement require pressure type verification before substitution.
