DP2-61E Pressure Sensor Equivalent & Substitute Parts

Part Overview

The DP2-61E is a vented gauge pressure sensor manufactured by Panasonic Industrial Automation Sales, designed for industrial automation applications. This sensor measures pressure up to 100 kPa (14.5 PSI) with analog voltage and PNP open collector output options. The product is currently obsolete, making equivalent substitute parts necessary for system maintenance, repair, and component replacement in existing installations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DP2-61E are identified based on the following critical parameters that determine functional compatibility:

Pressure Measurement Range: Operating pressure of 14.5 PSI (100 kPa) with maximum pressure capability of at least 71.07 PSI (490 kPa) ensures the substitute can handle the same pressure conditions.

Output Type: PNP open collector output is required to maintain signal compatibility with existing control systems and wiring configurations.

Voltage Supply Range: Supply voltage between 12V and 24V ensures the substitute operates within the same power distribution infrastructure.

Port Configuration: Female threaded port at 1/8" (3.18 mm) ensures mechanical compatibility with existing pneumatic/hydraulic connections.

Operating Temperature Range: -10°C to 50°C defines the environmental operating envelope.

Pressure Type: Gauge pressure measurement capability is essential for the intended application.

The PG-30-102R-P meets these core substitution criteria while offering enhanced specifications in certain areas.

Parameter Comparison

Engineering Selection Recommendations

The PG-30-102R-P from Nidec Components Corporation is a functional substitute for the obsolete DP2-61E. Both sensors share identical operating pressure ratings, temperature ranges, and package configurations. The PG-30-102R-P is currently in active production status, ensuring availability for replacement applications.

Compliance Considerations: Both parts meet RoHS requirements and carry identical MSL ratings, supporting use in regulated industrial environments.

Specification Enhancements: The PG-30-102R-P provides extended maximum pressure capability (±200 PSI vs 71.07 PSI) and includes temperature compensation, offering improved performance margins in industrial automation applications.

Interface Differences: Two implementation considerations exist:

Port thread standard difference (BSPP on DP2-61E vs BSPT on PG-30-102R-P) may require thread adapter or port modification depending on existing installation configuration.

Termination style difference (connector on DP2-61E vs cable on PG-30-102R-P) requires electrical interface adaptation during installation.

These differences are manageable through standard industrial adapters and do not affect core sensor functionality.

Frequently Asked Questions (FAQ)

Q: Can the PG-30-102R-P directly replace the DP2-61E without modifications?

A: The PG-30-102R-P is functionally equivalent for pressure measurement and signal output. However, two interface differences exist: the port thread standard (BSPP vs BSPT) and termination style (connector vs cable). These require appropriate adapters or interface modifications during installation.

Q: What is the difference between BSPP and BSPT port threads?

A: BSPP (British Standard Pipe Parallel) and BSPT (British Standard Pipe Tapered) are different thread standards. Both are 1/8" ports but use different thread profiles. Adapters are available to connect these different standards.

Q: Does the PG-30-102R-P output the same signal as the DP2-61E?

A: Both sensors provide PNP open collector output. The PG-30-102R-P specifies 1 V ~ 5 V output range. The DP2-61E also supports analog voltage output, though the specific range is not documented. The PNP open collector output is compatible with standard industrial control systems.

Q: Why does the PG-30-102R-P have a higher maximum pressure rating?

A: The PG-30-102R-P is designed as a compound pressure sensor with ±200 PSI maximum capability, compared to the DP2-61E at 71.07 PSI. This provides additional safety margin and allows use in higher-pressure applications while maintaining the same 14.5 PSI operating point.

Q: Are both sensors RoHS compliant?

A: Yes. The DP2-61E is RoHS Compliant, and the PG-30-102R-P is ROHS3 Compliant. Both meet regulatory requirements for industrial automation applications.

Q: What does "Temperature Compensated" mean on the PG-30-102R-P?

A: Temperature compensation adjusts sensor output to account for temperature-related measurement drift. This feature improves accuracy across the -10°C to 50°C operating range compared to uncompensated sensors.

Q: Can I use the PG-30-102R-P in the same mounting location as the DP2-61E?

A: Both sensors use identical 1/8" female threaded ports and Module Box with Display packaging. Physical mounting compatibility exists, but the port thread standard difference (BSPP vs BSPT) requires adapter consideration for the pneumatic/hydraulic connection.
