DPL03T Equivalent & Substitute Parts

Part Overview

The DPL03T is a piano DIP switch manufactured by APEM Inc., configured as a single-pole single-throw (SPST) switch with 3 positions. This component is rated for 50mA at 24VDC and features a through-hole, right-angle mounting configuration with gold-plated phosphor bronze contacts. The DPL03T is currently classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DPL03T is determined by the following critical parameters:

• Circuit Configuration: SPST topology must be maintained
• Number of Positions: 3-position requirement must be preserved
• Voltage Rating: 24VDC operation is mandatory
• Mounting Type: Through-hole, right-angle configuration required
• Pitch: 0.100" (2.54mm) standard pitch must be matched
• Actuator Type: Piano actuator style required
• Current Rating: Substitute must support minimum 50mA operation

The NDPL-03T-V qualifies as a substitute based on matching all critical parameters. However, the current rating differs at 25mA versus the original 50mA specification, which represents a functional limitation in maximum current handling capacity.

Parameter Comparison

Engineering Selection Recommendations

The NDPL-03T-V is an active production substitute for the obsolete DPL03T. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new designs and legacy system support.

The primary consideration for selection is current rating. The DPL03T supports 50mA operation, while the NDPL-03T-V is rated for 25mA. Applications requiring current levels between 25mA and 50mA must evaluate whether the NDPL-03T-V current rating is sufficient for the intended circuit function. Applications operating below 25mA are fully compatible with the substitute.

All other electrical and mechanical parameters are equivalent, including voltage rating, circuit topology, mounting configuration, and operating temperature range. The NDPL-03T-V maintains the same physical footprint and pitch spacing, enabling direct board-level substitution where current requirements permit.

Frequently Asked Questions (FAQ)

Q: Can the NDPL-03T-V directly replace the DPL03T in existing designs?

A: Direct substitution is possible if the application current requirement does not exceed 25mA. The NDPL-03T-V is rated for 25mA maximum, compared to the DPL03T's 50mA rating. All other electrical and mechanical parameters are equivalent.

Q: What are the key differences between these two parts?

A: The primary difference is current rating: DPL03T supports 50mA, while NDPL-03T-V supports 25mA. The NDPL-03T-V is an active production part, whereas the DPL03T is obsolete. All other specifications, including voltage, circuit configuration, mounting type, and pitch, are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both the DPL03T and NDPL-03T-V are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: What is the physical compatibility between these parts?

A: Both parts share identical mounting specifications: through-hole, right-angle configuration with 0.100" (2.54mm) pitch and 0.402" (10.20mm) height above board. Board-level substitution is mechanically feasible.

Q: Why is the DPL03T obsolete?

A: The DPL03T is classified as obsolete by the manufacturer. The NDPL-03T-V represents the active production alternative within the APEM Inc. DIP switch portfolio.
