DPL07T Equivalent & Substitute Parts

Part Overview

The DPL07T is a 7-position DIP switch manufactured by APEM Inc., featuring SPST (Single Pole Single Throw) circuitry with a piano actuator and through-hole right-angle mounting. This component is rated for 50mA at 24VDC and is designed for applications requiring reliable switching in compact form factors. The DPL07T is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DPL07T is determined by the following critical parameters that must remain consistent:

• Circuit configuration: SPST topology
• Number of positions: 7-position array
• Voltage rating: 24VDC minimum
• Actuator style: Piano type with raised level
• Mounting configuration: Through-hole, right-angle orientation
• Pitch spacing: 0.100" (2.54mm) full pitch
• Contact finish: Gold plating for reliability
• Operating temperature range: -20°C to 70°C minimum
• Termination: PC pin style

The NDPL-07T-V qualifies as a substitute based on matching these core parameters. However, the current rating differs: the substitute is rated for 25mA versus the original 50mA specification. This reduction in current capacity must be evaluated against actual application requirements.

Parameter Comparison

Engineering Selection Recommendations

The NDPL-07T-V is an active product from APEM Inc. and represents the current generation equivalent to the obsolete DPL07T. Both components maintain ROHS3 compliance and identical MSL ratings, ensuring compatibility with modern manufacturing and environmental standards.

The primary consideration for selection is the current rating differential. The DPL07T supports 50mA switching capacity, while the NDPL-07T-V is rated for 25mA. Applications operating at or below 25mA can directly substitute the NDPL-07T-V without circuit modification. Applications requiring the full 50mA capacity of the original part must either source remaining DPL07T inventory or redesign the switching circuit to accommodate the lower current rating of the substitute.

Both components share identical mechanical and electrical interface characteristics, including pitch, mounting orientation, actuator style, and operating temperature range, ensuring PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can the NDPL-07T-V directly replace the DPL07T in all applications?

A: Direct replacement is possible only when application current requirements do not exceed 25mA. The NDPL-07T-V is rated for 25mA versus the DPL07T's 50mA capacity. Verify your circuit's actual switching current before substitution.

Q: Are the physical dimensions identical between these parts?

A: The components share the same height above board (0.402"), pitch spacing (0.100"), and mounting configuration (through-hole, right-angle). Length differs slightly: DPL07T is 0.761" versus NDPL-07T-V at 0.750". This minor difference does not affect PCB layout compatibility.

Q: What is the difference in contact material specification?

A: The DPL07T specifies phosphor bronze contact material with gold finish. The NDPL-07T-V contact material is not specified in available documentation but maintains gold finish. Both achieve the same 2,000-cycle electrical life rating.

Q: Are both parts RoHS compliant?

A: Yes. Both the DPL07T and NDPL-07T-V are ROHS3 compliant and carry MSL rating 1 (unlimited moisture sensitivity level), suitable for standard manufacturing environments.

Q: What is the product status difference?

A: The DPL07T is classified as obsolete, indicating discontinued production. The NDPL-07T-V is active and currently manufactured, ensuring availability for new designs and ongoing support.
