Key Parameters

Substitute Part Grouping Explanation

The DP-102-M qualifies as a substitute for the DP2-42N based on the following critical parameters:

Matching Parameters:

• Manufacturer: Panasonic Industrial Automation Sales (same manufacturer ensures design compatibility)
• Pressure Type: Vented Gauge (identical pressure measurement principle)
• Output Type: NPN - Open Collector (compatible signal output architecture)
• Voltage Supply: 12V ~ 24V (identical operating voltage range)
• Port Style: Threaded (compatible mechanical interface)
• Termination Style: Connector (same connection method)
• Operating Temperature: -10°C ~ 50°C (identical thermal operating range)
• RoHS Status: ROHS3 Compliant (meets environmental compliance requirements)
• ECCN: EAR99 (same export classification)
• HTSUS Code: 9026.20.4000 (same tariff classification)

Functional Compatibility: The DP-102-M operates within an extended pressure range (-14.5 PSI ~ 145.04 PSI operating, -21.76 PSI ~ 217.56 PSI maximum), which encompasses the DP2-42N operating envelope. This extended range ensures the substitute can handle all pressure conditions specified for the original component.

Engineering Selection Recommendations

The DP-102-M is suitable as a substitute for the DP2-42N based on the following engineering criteria:

Product Status Consideration: The DP2-42N is classified as obsolete, while the DP-102-M maintains active product status. This ensures ongoing availability and manufacturer support for the substitute component.

Compliance Alignment: Both components meet RoHS environmental compliance requirements. The DP-102-M carries ROHS3 certification, representing current compliance standards. Both components share identical ECCN (EAR99) and HTSUS (9026.20.4000) classifications, ensuring regulatory consistency.

Electrical and Mechanical Compatibility: Identical voltage supply ranges (12V ~ 24V), output signal architecture (NPN - Open Collector), and operating temperature specifications (-10°C ~ 50°C) ensure direct functional compatibility within existing system designs.

Pressure Range Coverage: The DP-102-M operating pressure range (-14.5 PSI ~ 145.04 PSI) fully encompasses the DP2-42N specification (145.04 PSI nominal), with extended maximum pressure capability (217.56 PSI vs. 213.21 PSI), providing equivalent or superior performance margins.

Frequently Asked Questions (FAQ)

Q: Can the DP-102-M directly replace the DP2-42N in existing installations?

A: Yes. Both components share identical voltage supply (12V ~ 24V), output type (NPN - Open Collector), operating temperature range (-10°C ~ 50°C), and port style (threaded connector). The DP-102-M pressure range encompasses the DP2-42N specification.

Q: What is the primary difference between these two models?

A: The DP2-42N is obsolete, while the DP-102-M is an active product. The DP-102-M operates across an extended pressure range (-14.5 PSI ~ 145.04 PSI operating, -21.76 PSI ~ 217.56 PSI maximum) compared to the DP2-42N (145.04 PSI operating, 213.21 PSI maximum).

Q: Are there port size differences between the DP2-42N and DP-102-M?

A: Yes. The DP2-42N uses Female - 1/8" (3.18 mm) NPT port, while the DP-102-M uses Female - M5 port. Port adapters may be required depending on system plumbing configuration.

Q: Do both components meet current environmental compliance standards?

A: Yes. The DP2-42N is RoHS Compliant, and the DP-102-M is ROHS3 Compliant. Both meet current environmental regulations. Both share identical ECCN (EAR99) and HTSUS (9026.20.4000) classifications.

Q: What is the moisture sensitivity level for these components?

A: Both the DP2-42N and DP-102-M carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.
