DPL05 Equivalent & Substitute Parts

Part Overview

The DPL05 is a 5-position DIP switch manufactured by APEM Inc., featuring a piano actuator with SPST circuit configuration rated for 50mA at 24VDC. This component is designed for through-hole, right-angle mounting applications with PC pin termination and gold-plated phosphor bronze contacts. The DPL05 is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DPL05 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration (SPST)
• Number of positions (5)
• Voltage rating (24VDC)
• Actuator type (Piano)
• Mounting type (Through Hole, Right Angle)
• Pitch (0.100" / 2.54mm)
• Termination style (PC Pin)

Allowable Variation Parameters:

• Current rating: Substitute parts may have lower current ratings if application requirements do not exceed the substitute's rating
• Mechanical and electrical life cycles: Variations acceptable based on application duty cycle
• Contact material and finish: Variations acceptable if electrical performance requirements are met
• Body material composition: Variations acceptable if mechanical and environmental requirements are met
• Physical dimensions (length, height): Minor variations acceptable within board layout constraints

The NDPL-05-V qualifies as a substitute based on matching all mandatory parameters. The primary difference is a reduced current rating of 25mA versus the original 50mA specification.

Parameter Comparison

Engineering Selection Recommendations

The NDPL-05-V is an active product substitute for the obsolete DPL05. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new designs and legacy system support.

Selection between these parts depends on application current requirements. The DPL05 supports 50mA switching capacity, while the NDPL-05-V is rated for 25mA. Applications requiring current switching below 25mA can utilize the NDPL-05-V without functional compromise. Applications requiring the full 50mA capacity of the original DPL05 must source alternative components outside this substitution group.

Both components share identical mechanical interfaces, pitch spacing, and mounting orientation, enabling direct PCB layout compatibility. The NDPL-05-V's active product status provides superior long-term availability and supply chain stability compared to the obsolete DPL05.

Frequently Asked Questions (FAQ)

Q: Can the NDPL-05-V directly replace the DPL05 in existing designs?

A: Direct replacement is possible only if the application circuit operates at or below 25mA. The NDPL-05-V maintains identical mechanical mounting, pitch, and electrical interface characteristics. If the original design requires the full 50mA switching capacity, the NDPL-05-V is not suitable.

Q: Are there physical footprint differences between DPL05 and NDPL-05-V?

A: Both components share identical pitch (0.100" / 2.54mm) and height above board (0.402" / 10.20mm). The NDPL-05-V length is 0.550" (13.97mm) versus the DPL05 at 0.561" (14.25mm), a difference of 0.011" that does not affect PCB layout compatibility for standard through-hole applications.

Q: What is the primary technical difference between these parts?

A: The current rating is the primary specification difference. The DPL05 is rated for 50mA switching current, while the NDPL-05-V is rated for 25mA. All other electrical parameters, including voltage rating, circuit configuration, and operating temperature range, are identical.

Q: Are both parts suitable for new designs?

A: The NDPL-05-V is recommended for new designs due to its active product status. The DPL05 is obsolete and subject to availability constraints. The NDPL-05-V provides equivalent functionality for applications within its 25mA current specification.

Q: Do these components have different contact materials?

A: The DPL05 specifies phosphor bronze contacts with gold finish. The NDPL-05-V contact material is not specified in available documentation but maintains gold finish. Both components provide gold-plated contact surfaces suitable for standard switching applications.
