DP2-21F-P Pressure Sensor: Equivalent & Substitute Parts

Part Overview

The DP2-21F-P is a vented gauge pressure sensor manufactured by Panasonic Industrial Automation Sales, designed for industrial automation applications. This sensor operates at 100 kPa (14.5 PSI) nominal pressure with analog voltage and PNP open collector output capabilities. The product is currently obsolete, making identification of compatible substitute components essential for system maintenance, repair, and continued operation in existing installations.

Key Parameters

Substitute Part Grouping Explanation

The DP-101-N-P qualifies as a substitute for the DP2-21F-P based on the following critical parameters:

Matching Parameters:

• Pressure type: Both are vented gauge sensors
• Operating pressure range: Both operate at ±14.5 PSI (±100 kPa) nominal
• Output type: Both provide PNP open collector output
• Supply voltage: Both operate on 12V ~ 24V
• Port style: Both use threaded connections
• Termination: Both use connector-based termination
• Operating temperature range: Both function across -10°C ~ 50°C
• RoHS compliance: Both meet regulatory requirements

Functional Equivalence: The DP-101-N-P represents an active product from the DP-100 series, providing direct functional replacement for the obsolete DP2-21F-P. Both sensors share identical electrical interface specifications and pressure measurement capabilities within their respective operating ranges.

Parameter Comparison

Engineering Selection Recommendations

The DP-101-N-P is the designated substitute for the obsolete DP2-21F-P. Selection is based on:

Product Status: The DP2-21F-P is obsolete and no longer manufactured. The DP-101-N-P is an active product with current manufacturing support and availability.

Regulatory Compliance: Both components meet RoHS requirements. The DP-101-N-P carries ROHS3 certification, representing the current regulatory standard.

Electrical Compatibility: Identical supply voltage range (12V ~ 24V) and output type (PNP open collector) ensure direct integration into existing control circuits without modification.

Pressure Specifications: The DP-101-N-P maximum pressure rating (±72.52 PSI / ±500 kPa) exceeds the DP2-21F-P (71.07 PSI / 490 kPa), providing equivalent or superior performance envelope.

Port Configuration: The DP-101-N-P provides dual port options (M5 and 1/8" NPT), offering installation flexibility. The 1/8" NPT option maintains compatibility with existing DP2-21F-P installations.

Frequently Asked Questions (FAQ)

Q: Can the DP-101-N-P directly replace the DP2-21F-P in existing installations?

A: Yes. Both sensors share identical electrical specifications (12V ~ 24V supply, PNP open collector output), operating pressure range (100 kPa nominal), and threaded port configuration. The DP-101-N-P's 1/8" NPT port option provides mechanical compatibility with existing DP2-21F-P installations.

Q: What is the difference between the port configurations?

A: The DP2-21F-P provides a single Female 1/8" NPT port. The DP-101-N-P offers dual port options: Female M5 and Male 1/8" NPT. For direct replacement, use the 1/8" NPT connection.

Q: Are there differences in pressure measurement accuracy?

A: Accuracy specifications are not provided in the technical data for either component. Both sensors operate within the same pressure type classification (vented gauge) and nominal operating range (100 kPa).

Q: What is the significance of the ±14.5 PSI specification on the DP-101-N-P?

A: The ± notation indicates bidirectional pressure measurement capability. The DP-101-N-P can measure both positive and negative pressure deviations from atmospheric reference, while the DP2-21F-P specification indicates unidirectional measurement. Both operate at the same nominal 100 kPa pressure point.

Q: Are there packaging differences between these components?

A: The DP2-21F-P is supplied in a Module Box with Display. The DP-101-N-P is supplied in a standard Module Box. Both use connector-based termination and are rated MSL 1 (Unlimited moisture sensitivity).

Q: What certifications apply to the DP-101-N-P?

A: The DP-101-N-P is ROHS3 compliant, RoHS certified, and classified under ECCN EAR99 with HTSUS code 9026.20.4000, matching the regulatory classification of the DP2-21F-P.
