DP2-61 Pressure Sensor Equivalent & Substitute Parts

Part Overview

The DP2-61 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 NPN open collector output options. The product is currently obsolete, making equivalent substitute parts necessary for system maintenance, repair, and component sourcing in ongoing industrial applications.

Key Parameters

Substitute Part Grouping Explanation

The PG-30-102R-N from Nidec Components Corporation qualifies as a functional substitute for the DP2-61 based on the following critical parameters:

Matching Parameters:

• Port size and style: Female - 1/8" (3.18 mm) BSPT threaded connection
• Output type: NPN - Open Collector
• Operating temperature range: -10°C ~ 50°C
• Package configuration: Module Box with Display
• Moisture sensitivity level: 1 (Unlimited)
• RoHS compliance status: Both parts meet RoHS standards

Allowable Variations:

• Pressure type: DP2-61 is vented gauge; PG-30-102R-N is compound gauge. Compound gauges measure both positive and negative pressure differentials, providing broader measurement capability.
• Operating pressure: DP2-61 operates at 14.5 PSI (100 kPa); PG-30-102R-N operates at ±14.5 PSI (±100 kPa). The substitute accommodates the original specification within its range.
• Voltage supply: DP2-61 requires 12V ~ 24V; PG-30-102R-N accepts 10.8V ~ 30V. The substitute's wider voltage range encompasses the original requirement.
• Maximum pressure: DP2-61 rated to 71.07 PSI (490 kPa); PG-30-102R-N rated to ±200 PSI (±1378.95 kPa). The substitute provides higher pressure tolerance.
• Output signal: DP2-61 provides 1V ~ 5V output range; PG-30-102R-N also provides 1V ~ 5V output range.
• Termination: DP2-61 uses connector termination; PG-30-102R-N uses cable termination. Both are standard industrial configurations.

Engineering Selection Recommendations

The PG-30-102R-N is an active product from Nidec Components Corporation and represents a viable substitute for the obsolete DP2-61. Selection should be based on the following engineering criteria:

Product Status Consideration: The DP2-61 is obsolete, while the PG-30-102R-N is active and currently in production. This ensures long-term availability and supply chain continuity for replacement and new installations.

Compliance Alignment: Both parts meet RoHS standards and share identical ECCN and HTSUS classifications, ensuring regulatory and export compliance equivalence.

Mechanical Interface: Identical port specifications (Female - 1/8" BSPT threaded) allow direct mechanical substitution without adapter requirements.

Electrical Interface: Both sensors provide NPN open collector output with identical signal ranges, ensuring compatibility with existing control circuits and signal conditioning equipment.

Operational Envelope: The PG-30-102R-N's wider voltage supply range (10.8V ~ 30V) and higher maximum pressure rating (±200 PSI) provide operational margin beyond the original DP2-61 specifications.

Termination Difference: The DP2-61 uses connector termination while the PG-30-102R-N uses cable termination. System integration must account for this difference in wiring methodology.

Frequently Asked Questions (FAQ)

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

A: The PG-30-102R-N is electrically compatible with the DP2-61 in terms of output type, signal range, and voltage supply requirements. However, the termination style differs: the DP2-61 uses connector termination while the PG-30-102R-N uses cable termination. Integration requires appropriate wiring accommodation for the cable connection method.

Q: What is the difference between vented gauge and compound pressure measurement?

A: The DP2-61 measures vented gauge pressure, which references atmospheric pressure as zero. The PG-30-102R-N measures compound pressure, capable of measuring both positive and negative pressure differentials. For applications requiring only positive gauge pressure measurement, the PG-30-102R-N operates within the DP2-61's specification range.

Q: Are the port connections identical between these sensors?

A: Yes. Both sensors feature Female - 1/8" (3.18 mm) BSPT threaded ports, allowing direct mechanical substitution without adapter fittings.

Q: Does the wider voltage supply range of the PG-30-102R-N affect system compatibility?

A: No. The PG-30-102R-N accepts 10.8V ~ 30V, which encompasses the DP2-61's 12V ~ 24V requirement. Systems powered within the original voltage range will operate the substitute sensor without modification.

Q: What is the significance of the higher maximum pressure rating on the PG-30-102R-N?

A: The PG-30-102R-N is rated to ±200 PSI (±1378.95 kPa) compared to the DP2-61's 71.07 PSI (490 kPa). This provides additional safety margin and allows the substitute to be used in applications with higher transient pressure spikes without sensor damage.

Q: Are both sensors RoHS compliant?

A: Yes. The DP2-61 is RoHS Compliant, and the PG-30-102R-N is ROHS3 Compliant. Both meet current RoHS standards for hazardous substance restrictions.

Q: What is the difference in termination style, and does it affect installation?

A: The DP2-61 uses connector termination (plug-in connection), while the PG-30-102R-N uses cable termination (direct wire connection). Installation methodology differs, but both are standard industrial configurations. System design must accommodate the cable connection approach of the substitute.
