DPL02T Equivalent & Substitute Parts

Part Overview

The DPL02T is a piano DIP switch manufactured by APEM Inc., designed for through-hole, right-angle mounting applications requiring SPST (Single Pole Single Throw) switching at 24VDC with a 50mA current rating. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement planning. The DPL02T features a 2-position configuration with gold-plated phosphor bronze contacts, epoxy sealed terminals, and a raised piano actuator suitable for manual switching operations.

Substitute Part Grouping Explanation

Substitute part identification for the DPL02T is based on the following critical parameters that define functional equivalence:

• Circuit Configuration: SPST topology must be maintained
• Number of Positions: 2-position requirement
• Voltage Rating: 24VDC operation
• Actuator Type & Level: Piano actuator with raised profile for consistent user interface
• Mounting Configuration: Through-hole, right-angle orientation with 0.100" (2.54mm) pitch
• Height Above Board: 0.402" (10.20mm) to ensure PCB layout compatibility
• Contact Finish: Gold plating for corrosion resistance and reliable electrical contact
• Operating Temperature: -20°C to 70°C range
• Compliance: ROHS3 and REACH compliance for regulatory alignment

The NDPL-02T-V from APEM Inc. meets all critical substitution criteria with one exception: current rating is reduced to 25mA versus the original 50mA specification. This substitution is valid only for applications where the circuit load does not exceed 25mA.

Parameter Comparison

Engineering Selection Recommendations

The NDPL-02T-V is the primary substitute for the obsolete DPL02T. Both components are manufactured by APEM Inc. and maintain identical mechanical and electrical interfaces for through-hole PCB assembly. The NDPL-02T-V carries active product status, ensuring long-term availability and supply chain continuity.

Selection of the NDPL-02T-V requires verification that circuit current requirements do not exceed 25mA. Applications designed for the full 50mA capability of the DPL02T will require circuit redesign or alternative component sourcing.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and commercial applications. The identical operating temperature range (-20°C to 70°C) and electrical life rating (2,000 cycles) ensure functional parity in standard operating environments.

Frequently Asked Questions (FAQ)

Q: Can the NDPL-02T-V directly replace the DPL02T in all applications?

A: Direct replacement is possible only if circuit current does not exceed 25mA. The NDPL-02T-V has a reduced current rating (25mA) compared to the DPL02T (50mA). Applications requiring the full 50mA capability require alternative sourcing or circuit modification.

Q: Are the mechanical dimensions identical between DPL02T and NDPL-02T-V?

A: Yes. Both components share identical height above board (0.402"), pitch (0.100"), and through-hole right-angle mounting configuration, ensuring PCB layout compatibility without modification.

Q: What is the primary reason for substitution?

A: The DPL02T is classified as obsolete. The NDPL-02T-V is an active product from the same manufacturer, providing continued availability and supply chain support.

Q: Are there compliance differences between the two parts?

A: No. Both components are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements.

Q: What is the contact material specification for the NDPL-02T-V?

A: Contact material specification is not provided in the available technical data for the NDPL-02T-V. Both parts feature gold-plated contacts suitable for 24VDC switching applications.
