DP2-22 Pressure Sensor Equivalent & Substitute Parts

Part Overview

The DP2-22 is an NPN open collector pressure sensor manufactured by Panasonic Industrial Automation Sales, designed for industrial automation applications requiring vented gauge pressure measurement. This sensor operates within a 12V to 24V DC supply range and features a female 1/8" BSPT threaded port connection. The DP2-22 is classified as obsolete, making identification of functionally equivalent substitute components essential for system maintenance, repair, and new design implementations where legacy component replacement is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the DP2-22 must satisfy the following critical parameters to ensure functional equivalence:

Mandatory Matching Criteria:

• Pressure type: Vented gauge
• Output type: NPN - Open Collector
• Voltage supply range: 12V ~ 24V DC
• Operating temperature range: -10°C ~ 50°C
• Termination style: Connector
• Manufacturer: Panasonic Industrial Automation Sales
• RoHS compliance status

Allowable Variation Parameters:

• Port size and style (mechanical interface adaptation may be required)
• Maximum pressure rating (substitute must meet or exceed the DP2-22 maximum of 213.21 PSI / 1470 kPa)
• Operating pressure range (substitute range may be broader)

The DP-102-M qualifies as a substitute based on matching output type, voltage supply, operating temperature, termination style, and RoHS compliance. Port size differs (M5 versus 1/8" BSPT), requiring mechanical adapter consideration during integration.

Parameter Comparison

Engineering Selection Recommendations

The DP-102-M is the designated substitute for the obsolete DP2-22 based on the following engineering criteria:

Functional Equivalence: Both sensors share identical output topology (NPN - Open Collector), voltage supply specifications (12V ~ 24V DC), operating temperature range (-10°C ~ 50°C), and pressure measurement type (vented gauge). Signal conditioning and control interface compatibility is maintained.

Compliance Status: The DP-102-M meets current ROHS3 compliance requirements, exceeding the RoHS compliance of the DP2-22. Both sensors carry unlimited moisture sensitivity rating (MSL 1), indicating no special handling requirements during storage or assembly.

Pressure Rating Compatibility: The DP-102-M maximum pressure specification (217.56 PSI / 1500 kPa) exceeds the DP2-22 maximum (213.21 PSI / 1470 kPa), ensuring adequate safety margin. The DP-102-M operating range extends into negative gauge pressure (-14.5 PSI / -100 kPa), providing broader measurement capability than the DP2-22 positive-only range.

Integration Consideration: Port connection differs between models. The DP2-22 uses 1/8" BSPT female threading, while the DP-102-M uses M5 female threading. System integration requires mechanical adapter specification to accommodate this dimensional difference.

Active Production Status: The DP-102-M is classified as active product, ensuring continued availability and supply chain stability for new installations and ongoing maintenance requirements.

Frequently Asked Questions (FAQ)

Q: Can the DP-102-M directly replace the DP2-22 without modification?

A: Electrical and signal compatibility is direct. Mechanical port connection requires adaptation due to thread standard difference (1/8" BSPT versus M5). Specify appropriate threaded adapter for pressure line integration.

Q: What is the significance of the DP-102-M broader pressure range?

A: The DP-102-M operating range (-14.5 PSI ~ 145.04 PSI) includes negative gauge pressure measurement capability absent in the DP2-22 (145.04 PSI positive only). For applications requiring only positive gauge measurement, both sensors perform identically within the overlapping range.

Q: Are there differences in connector termination between these sensors?

A: Both sensors use connector termination style. Verify connector type and pin configuration match your existing wiring harness or control interface before installation.

Q: Why is the DP2-22 classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The DP-102-M represents the current active equivalent within the Panasonic DP series product line.

Q: Does the DP-102-M require different power supply specifications?

A: No. Both sensors operate identically on 12V ~ 24V DC supply. Existing power infrastructure requires no modification.

Q: What packaging differences exist between these sensors?

A: The DP2-22 ships in module box with display packaging. The DP-102-M uses standard module packaging. Verify display functionality requirements for your application before substitution.
