DP4-52 Pressure Sensor Equivalent & Substitute Parts

Part Overview

The DP4-52 is a vented gauge pressure sensor manufactured by Panasonic Industrial Automation Sales, designed for industrial automation applications. It features NPN open collector output with an operating pressure range of 0 to 1 MPA (145.04 PSI) and operates across 12V to 24V supply voltage. The product is classified as obsolete, making identification of functionally equivalent active alternatives essential for system maintenance, component sourcing, and design continuity in industrial automation installations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DP4-52 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Pressure type classification (vented gauge)
• Output signal type (NPN open collector)
• Voltage supply range (12V ~ 24V)
• Port interface (Female M5 threaded)
• Operating pressure range capability (minimum 0 to 1 MPA)
• Operating temperature range (minimum 0°C ~ 50°C)

Identified Substitutes:

DP-102-N-P-J: Shares vented gauge pressure type, 12V ~ 24V supply voltage, Female M5 port, and threaded port style. However, features PNP output type (not NPN), extended operating pressure range (-0.1 to 1 MPA), and expanded temperature range (-10°C ~ 50°C). Output type difference requires circuit-level evaluation.

DP-002: Matches NPN open collector output type, 12V ~ 24V supply voltage, Female M5 port, threaded port style, and identical operating pressure range (0 to 1 MPA). Termination style differs (cable/wire leads versus connector). Product status is active with ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

DP-002 Substitution: This part represents the closest functional equivalent to the DP4-52. It maintains identical NPN open collector output type, matching operating pressure range (0 to 1 MPA), identical voltage supply specification (12V ~ 24V), and compatible port interface (Female M5 threaded). The primary difference is termination style (cable/wire leads instead of connector). The DP-002 is active product status with ROHS3 compliance, ensuring ongoing availability and regulatory alignment.

DP-102-N-P-J Substitution: This part shares the same manufacturer, vented gauge pressure type, voltage supply range, and port interface. However, the output type is PNP rather than NPN, which represents a fundamental signal logic difference. This substitution requires verification that the receiving circuit can accommodate PNP signal logic. The extended operating pressure range (-0.1 to 1 MPA) and expanded temperature range (-10°C ~ 50°C) provide additional operational margin. Product status is active with ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can DP-102-N-P-J directly replace DP4-52 in existing installations?

A: Direct replacement requires circuit-level compatibility assessment. The DP-102-N-P-J uses PNP output logic while the DP4-52 uses NPN output logic. If the receiving circuit is designed specifically for NPN input signals, the PNP output will not function correctly without circuit modification. Verify the input stage of your control system before substitution.

Q: What is the primary advantage of DP-002 as a substitute?

A: The DP-002 maintains identical output type (NPN open collector), operating pressure range (0 to 1 MPA), and voltage supply specification (12V ~ 24V) as the DP4-52. The only functional difference is termination style. If your installation uses cable/wire lead connections, the DP-002 provides direct functional equivalence with active product status.

Q: Does the extended temperature range of DP-102-N-P-J provide additional capability?

A: The DP-102-N-P-J operates from -10°C to 50°C compared to the DP4-52 range of 0°C to 50°C. This extended lower temperature limit provides operational capability in colder environments. However, this advantage is only relevant if your application requires operation below 0°C.

Q: Are there port interface compatibility considerations?

A: All three parts feature Female M5 threaded ports as the primary interface. The DP-102-N-P-J additionally offers a Male 1/8" NPT port option. Verify your existing pneumatic or hydraulic line connections use the Female M5 interface before substitution.

Q: What is the significance of product status differences?

A: The DP4-52 is classified as obsolete, indicating discontinued manufacturing and potential supply constraints. Both DP-002 and DP-102-N-P-J are active products with current manufacturing and established supply chains, ensuring long-term component availability for system maintenance and future orders.

Q: How do RoHS compliance levels affect substitution decisions?

A: The DP4-52 carries RoHS Compliant status, while both substitute parts carry ROHS3 Compliant status. ROHS3 represents a more recent compliance standard. Both substitute parts meet or exceed the regulatory requirements of the original part, making them suitable for applications with RoHS requirements.
