DPL12UBT Equivalent & Substitute Parts

Part Overview

The DPL12UBT is a 12-position DIP switch manufactured by APEM Inc., featuring a piano actuator with SPST circuit configuration rated for 50mA at 24VDC. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations. The switch is designed for through-hole, right-angle mounting with PC pin termination and includes epoxy sealed terminals with tape seal protection.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DPL12UBT must maintain compatibility across the following critical parameters:

• Circuit configuration: SPST (Single Pole, Single Throw)
• Position count: 12 positions
• Voltage rating: 24VDC minimum
• Actuator type: Piano with raised level
• Mounting configuration: Through hole, right angle
• Pitch spacing: 0.100" (2.54mm)
• Termination style: PC pin
• Operating temperature range: -20°C to 70°C minimum

The NDPL-12T-V meets these core compatibility requirements. While the current rating differs (25mA versus 50mA), this represents a derating condition acceptable for applications where the original 50mA specification exceeds actual circuit requirements. Both parts share identical voltage ratings, actuator configurations, mounting styles, and pitch specifications.

Parameter Comparison

Engineering Selection Recommendations

The NDPL-12T-V is the primary substitute for the obsolete DPL12UBT. Both components are manufactured by APEM Inc. and maintain identical mechanical and electrical interface specifications. The NDPL-12T-V carries active product status, ensuring continued availability and supply chain support.

The reduced current rating of the NDPL-12T-V (25mA versus 50mA) is acceptable for applications where circuit current requirements do not exceed 25mA. For applications requiring the full 50mA capability of the original DPL12UBT, alternative sources must be evaluated or circuit redesign considered.

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

Frequently Asked Questions (FAQ)

Q: Can the NDPL-12T-V directly replace the DPL12UBT in existing designs?

A: Yes, for applications where the circuit current does not exceed 25mA. The NDPL-12T-V maintains identical mechanical mounting, pitch spacing, actuator configuration, and voltage rating. Verify that your application current requirement does not exceed the 25mA specification of the substitute part.

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

A: The current rating differs: DPL12UBT is rated for 50mA while NDPL-12T-V is rated for 25mA. All other electrical and mechanical parameters are equivalent.

Q: Are both parts RoHS compliant?

A: Yes, both the DPL12UBT and NDPL-12T-V are ROHS3 compliant and REACH unaffected, meeting current regulatory standards.

Q: What is the pitch spacing for these DIP switches?

A: Both parts use 0.100" (2.54mm) pitch spacing, standard for 12-position DIP switch configurations.

Q: Can I use the NDPL-12T-V in a new design?

A: Yes. The NDPL-12T-V carries active product status and is recommended for new designs requiring 12-position SPST DIP switch functionality at 24VDC with current requirements up to 25mA.

Q: Are the mounting footprints identical?

A: Yes, both parts feature through-hole, right-angle mounting with PC pin termination and identical height above board (0.402" / 10.20mm), ensuring direct PCB footprint compatibility.
