DPL02 Equivalent & Substitute Parts

Part Overview

The DPL02 is a piano DIP switch manufactured by APEM Inc., configured as a single-pole single-throw (SPST) switch with 2 positions. It is rated for 50mA at 24VDC and features a through-hole, right-angle mounting with PC pin termination. The DPL02 is classified as obsolete, making identification of equivalent and substitute parts necessary for ongoing system maintenance and new design implementations where this component is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DPL02 is determined by the following critical parameters:

• Circuit Configuration: SPST topology must be maintained
• Number of Positions: 2-position requirement
• Voltage Rating: 24VDC operation
• Mounting Type: Through-hole, right-angle configuration
• Termination Style: PC pin connection
• Pitch: 0.100" (2.54mm) spacing
• Actuator Type: Piano-style raised actuator
• Contact Finish: Gold plating

The NDPL-02-V qualifies as a substitute part based on matching all critical parameters. However, the current rating differs: the NDPL-02-V is rated for 25mA versus the DPL02's 50mA. This reduction in current capacity must be evaluated against the application's actual current draw requirements.

Parameter Comparison

Engineering Selection Recommendations

The NDPL-02-V is an active product from APEM Inc. and maintains full compliance with ROHS3 and REACH requirements, matching the DPL02's regulatory status. Both parts share identical mechanical dimensions, mounting configuration, and electrical life ratings.

The primary consideration for substitution is the current rating differential. The NDPL-02-V operates at 25mA maximum, compared to the DPL02's 50mA rating. Selection of the NDPL-02-V is appropriate when the application's actual current draw does not exceed 25mA. For applications requiring the full 50mA capacity of the original DPL02, alternative parts with higher current ratings must be sourced.

The NDPL-02-V's active product status provides supply chain continuity and ongoing manufacturer support, addressing the obsolescence of the DPL02.

Frequently Asked Questions (FAQ)

Q: Can the NDPL-02-V directly replace the DPL02 in all applications?

A: Direct replacement is possible only when the application's actual current draw does not exceed 25mA. The NDPL-02-V is rated for 25mA maximum, while the DPL02 is rated for 50mA. If the circuit requires current above 25mA, the NDPL-02-V will not provide adequate current capacity.

Q: Are the physical dimensions identical between DPL02 and NDPL-02-V?

A: The height above board (0.402" / 10.20mm), pitch (0.100" / 2.54mm), and mounting configuration are identical. The NDPL-02-V length is 0.250" (6.35mm) versus the DPL02's 0.261" (6.63mm), a difference of 0.011" that does not affect PCB layout compatibility for through-hole, right-angle mounting.

Q: What is the difference in contact material between these parts?

A: The DPL02 specifies phosphor bronze contact material with gold finish. The NDPL-02-V contact material is not specified in the provided data. Both parts feature gold contact finish.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the DPL02 and NDPL-02-V are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Why is the DPL02 obsolete?

A: The DPL02 is classified as obsolete by the manufacturer. The NDPL-02-V represents the active product line continuation from APEM Inc. for this switch category.
