DP3-22 Pressure Sensor Equivalent & Substitute Parts

Part Overview

The DP3-22 is an obsolete pressure sensor manufactured by Panasonic Industrial Automation Sales, designed for industrial automation applications requiring vented gauge pressure measurement. The sensor operates at 1 MPA (145.04 PSI) nominal pressure with NPN open collector output and dual voltage supply compatibility (12V ~ 24V). Due to its obsolete product status, identifying functionally equivalent active alternatives is essential for system maintenance, redesign, and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

The DP-102 qualifies as a functional substitute for the DP3-22 based on the following critical parameters:

Matching Parameters:

• Pressure type: Vented gauge (both sensors)
• Output type: NPN - Open Collector (identical signal interface)
• Voltage supply: 12V ~ 24V (compatible power requirements)
• Port style: Threaded (mechanical interface compatibility)
• Operating temperature range: -10°C ~ 50°C (identical thermal operating window)
• RoHS compliance: Both meet environmental standards
• ECCN and HTSUS classifications: Identical regulatory codes

Functional Compatibility: The DP-102 operates across an extended pressure range (-14.5 PSI ~ 145.04 PSI / -100 kPa ~ 1000 kPa), which encompasses the DP3-22 nominal operating pressure of 145.04 PSI (1000 kPa). The maximum pressure rating of the DP-102 (217.56 PSI / 1500 kPa) exceeds the DP3-22 maximum (213.21 PSI / 1470 kPa), providing equivalent or superior pressure handling capability.

Port Configuration: The DP-102 offers dual port options (Female M5 and Male 1/8" BSPT), providing mechanical flexibility. The Male 1/8" BSPT port directly matches the DP3-22 Female 1/8" BSPT port configuration for threaded connection compatibility.

Parameter Comparison

Engineering Selection Recommendations

The DP-102 is the designated substitute for the obsolete DP3-22 based on functional equivalence and regulatory compliance alignment.

Product Status Consideration: The DP3-22 is classified as obsolete, making long-term procurement and support unavailable. The DP-102 maintains active product status with Panasonic Industrial Automation Sales, ensuring continued availability, technical support, and supply chain reliability.

Compliance and Certification: Both sensors meet RoHS environmental standards. The DP-102 carries ROHS3 certification, representing the current regulatory requirement level. Both components share identical ECCN (EAR99) and HTSUS (9026.20.4000) classifications, confirming equivalent export and tariff treatment.

Electrical and Mechanical Compatibility: Identical voltage supply ranges (12V ~ 24V), output signal types (NPN - Open Collector), and operating temperature windows (-10°C ~ 50°C) ensure direct integration into existing control circuits without modification. The threaded port interface and 1/8" BSPT male connector on the DP-102 provide direct mechanical compatibility with the DP3-22 female port.

Pressure Range Coverage: The DP-102 operating range (-100 kPa ~ 1000 kPa) fully encompasses the DP3-22 nominal operating point (1000 kPa). The extended maximum pressure rating (1500 kPa vs. 1470 kPa) provides equivalent or superior pressure handling without performance degradation.

Frequently Asked Questions (FAQ)

Q: Can the DP-102 directly replace the DP3-22 in existing installations?

A: Yes. The DP-102 provides electrical and mechanical compatibility through matching NPN open collector output, identical voltage supply range (12V ~ 24V), and compatible threaded port configuration (1/8" BSPT). No circuit modifications are required.

Q: What is the primary difference between the DP3-22 and DP-102?

A: The DP3-22 is obsolete; the DP-102 is an active product. The DP-102 offers an extended pressure measurement range (-100 kPa ~ 1000 kPa) compared to the DP3-22 fixed nominal rating (1000 kPa), providing additional measurement flexibility. The DP-102 also features dual port options (M5 and 1/8" BSPT) versus the single 1/8" BSPT port on the DP3-22.

Q: Are there packaging differences between these sensors?

A: Yes. The DP3-22 is supplied in a Module Box with Display configuration, while the DP-102 is packaged as a Module. Both maintain identical moisture sensitivity levels (MSL 1 - Unlimited) and environmental compliance ratings.

Q: Do both sensors operate across the same temperature range?

A: Yes. Both the DP3-22 and DP-102 operate within -10°C ~ 50°C, ensuring thermal compatibility in equivalent industrial automation environments.

Q: What regulatory certifications apply to both sensors?

A: Both sensors are RoHS compliant and share identical ECCN (EAR99) and HTSUS (9026.20.4000) classifications. The DP-102 carries current ROHS3 certification. Both meet the same export control and tariff requirements.
