Key Parameters

Substitute Part Grouping Explanation

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

• Output Type: Both sensors provide PNP open collector output, ensuring electrical compatibility with existing control circuits
• Voltage Supply: Both operate within the 12V to 24V DC range, allowing direct integration into current power systems
• Pressure Type: Both are vented gauge pressure sensors, maintaining identical measurement methodology
• Operating Temperature Range: Both function across -10°C to 50°C, preserving thermal operating envelope
• Port Style: Both feature threaded connections for pneumatic integration
• Termination Style: Both use connector-based termination
• RoHS Compliance: Both meet environmental regulatory requirements
• Manufacturer: Both are manufactured by Panasonic Industrial Automation Sales

The DP-102-M-P operates across an extended pressure range (-14.5 PSI to 145.04 PSI operating; -21.76 PSI to 217.56 PSI maximum) compared to the DP2-42E, providing broader measurement capability within the same electrical and mechanical framework.

Engineering Selection Recommendations

The DP-102-M-P is the designated substitute for the obsolete DP2-42E. Selection is justified on the following basis:

• Product Status Alignment: The DP-102-M-P is active production status, ensuring ongoing availability and supply chain continuity
• Regulatory Compliance: The DP-102-M-P meets ROHS3 compliance, exceeding the RoHS compliance of the original part and satisfying current environmental standards
• Electrical Compatibility: Identical output type (PNP open collector) and voltage supply range (12V ~ 24V DC) ensure direct circuit integration without modification
• Mechanical Compatibility: Both sensors feature threaded port connections and connector-based termination, supporting existing pneumatic and electrical infrastructure
• Operational Envelope: The DP-102-M-P maintains the same operating temperature range and extends pressure measurement capability, providing equivalent or enhanced functionality

Frequently Asked Questions (FAQ)

Q: Can the DP-102-M-P directly replace the DP2-42E without circuit modifications?

A: Yes. Both sensors provide identical output type (PNP open collector), voltage supply range (12V ~ 24V DC), and termination style (connector). Direct electrical substitution is supported.

Q: What is the primary difference between the DP2-42E and DP-102-M-P?

A: The DP-102-M-P operates across an extended pressure range, including negative gauge pressures (-14.5 PSI to 145.04 PSI operating; -21.76 PSI to 217.56 PSI maximum), compared to the DP2-42E which operates at positive gauge pressures only (145.04 PSI operating; 213.21 PSI maximum). Both maintain identical electrical characteristics and operating temperature envelope.

Q: Are there port size differences between these sensors?

A: Yes. The DP2-42E features a Female 1/8" (3.18 mm) BSPP port, while the DP-102-M-P features a Female M5 port. Pneumatic connection adapters may be required depending on system configuration.

Q: Does the DP-102-M-P meet current environmental compliance standards?

A: Yes. The DP-102-M-P is ROHS3 compliant, meeting current environmental regulatory requirements. The original DP2-42E is RoHS compliant, representing an earlier compliance standard.

Q: What is the packaging difference?

A: The DP2-42E is supplied in Module Box with Display packaging. The DP-102-M-P is supplied in Bulk packaging. Both use identical connector-based termination.
