DP4-57P Pressure Sensor: Equivalent & Substitute Parts

Part Overview

The DP4-57P is a compound pressure sensor manufactured by Panasonic Industrial Automation Sales, designed for industrial automation applications. It features PNP open collector output with a 12V to 24V supply voltage and operates within a ±14.5PSI (±100kPa) pressure range. The product is currently obsolete, making identification of functionally equivalent alternatives essential for system maintenance and component replacement in existing installations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DP4-57P is determined by the following critical parameters:

Primary Matching Criteria:

• Output Type: PNP - Open Collector (mandatory match)
• Voltage Supply: 12V ~ 24V (mandatory match)
• Operating Pressure: ±14.5PSI (±100kPa) (mandatory match)
• Port Size: Female - M5 (mandatory match)
• Port Style: Threaded (mandatory match)

Secondary Compatibility Factors:

• Pressure Type: Compound (preferred but not absolute)
• Maximum Pressure: Must equal or exceed ±71.07PSI (±490kPa)
• Operating Temperature: Must encompass or exceed 0°C ~ 50°C range
• RoHS Compliance: Required for regulatory alignment

Both identified substitute parts meet the primary matching criteria and maintain compatibility with the original DP4-57P electrical and mechanical interface requirements.

Engineering Selection Recommendations

DP-101-N-P (Panasonic Industrial Automation Sales)

This substitute maintains Panasonic manufacturing continuity and is currently in active production status. It matches all primary electrical and mechanical interface requirements. The DP-101-N-P offers an extended operating temperature range (-10°C to 50°C) and marginally higher maximum pressure rating (±72.52PSI vs. ±71.07PSI). The pressure type differs (vented gauge vs. compound), which may affect performance in specific pressure measurement scenarios. ROHS3 compliance exceeds the original RoHS requirement. Port configuration includes both M5 female and 1/8" NPT male options, providing installation flexibility.

PS30-102R-P (Nidec Components Corporation)

This substitute provides cross-manufacturer compatibility while maintaining all critical electrical and mechanical specifications. The PS30-102R-P features a significantly higher maximum pressure rating (±200PSI), temperature compensated design, and extended operating temperature range (-10°C to 50°C). Pressure type remains compound, matching the original specification. Termination style differs (cable vs. connector), requiring evaluation of integration requirements. ROHS3 compliance and identical moisture sensitivity rating ensure regulatory alignment. Accuracy specification (±1%) is provided for this substitute.

Both substitutes are currently in active production with adequate inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the DP-101-N-P directly replace the DP4-57P in existing installations?

A: Yes, provided the pressure measurement type (vented gauge vs. compound) is compatible with your application. The DP-101-N-P matches all electrical interface requirements (PNP open collector, 12V-24V supply) and mechanical port specifications (Female M5 threaded). Verify that the vented gauge configuration does not conflict with your pressure measurement requirements.

Q: What is the primary difference between the DP-101-N-P and PS30-102R-P substitutes?

A: The DP-101-N-P maintains Panasonic manufacturing and vented gauge pressure type. The PS30-102R-P is manufactured by Nidec Components Corporation, retains compound pressure type, includes temperature compensation, and features a substantially higher maximum pressure rating (±200PSI vs. ±72.52PSI). Termination style also differs: DP-101-N-P uses connector termination while PS30-102R-P uses cable termination.

Q: Are both substitutes RoHS compliant?

A: Yes. Both DP-101-N-P and PS30-102R-P are ROHS3 compliant, exceeding the original DP4-57P RoHS compliance requirement.

Q: Does the extended operating temperature range of the substitutes affect compatibility?

A: No. Both substitutes support the original 0°C to 50°C operating range and extend it further (-10°C to 50°C). This provides enhanced operational flexibility without compromising compatibility with the original specification.

Q: What is the significance of the "temperature compensated" feature in the PS30-102R-P?

A: Temperature compensation adjusts sensor output to account for temperature-induced variations in pressure readings. This feature improves measurement accuracy across the operating temperature range but is not present in the original DP4-57P specification.

Q: Can I use the PS30-102R-P if my system requires connector termination?

A: The PS30-102R-P uses cable termination rather than connector termination. If your installation requires connector termination, the DP-101-N-P is the appropriate choice. Adapter solutions may be available but require separate evaluation.
