DPL12T Equivalent & Substitute Parts

Part Overview

The DPL12T is a 12-position DIP switch manufactured by APEM Inc., designed for through-hole, right-angle mounting applications requiring SPST switching at 24VDC with a 50mA current rating. This component features a piano actuator with gold-plated phosphor bronze contacts and is sealed with epoxy terminals for environmental protection.

The DPL12T is classified as obsolete. Identifying equivalent and substitute parts is necessary to support ongoing maintenance, repair, and new design requirements where original inventory becomes depleted or unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DPL12T is determined by the following critical parameters:

• Circuit Configuration: Must be SPST (Single Pole, Single Throw)
• Number of Positions: Must be 12
• Voltage Rating: Must be 24VDC
• Actuator Type: Must be Piano with raised actuator level
• Mounting Type: Must be Through Hole, Right Angle
• Pitch: Must be 0.100" (2.54mm)
• Termination Style: Must be PC Pin
• Operating Temperature Range: Must support -20°C to 70°C minimum

The NDPL-12T-V meets all mandatory substitution criteria. The primary difference is a reduced current rating of 25mA versus the original 50mA specification. This reduction represents a functional constraint that must be evaluated against application requirements.

Engineering Selection Recommendations

The NDPL-12T-V is an active product from the same manufacturer (APEM Inc.) and maintains full compliance with ROHS3 and REACH requirements. It preserves all mechanical and electrical interface characteristics of the DPL12T, including mounting footprint, pitch, and actuator geometry.

Selection of the NDPL-12T-V requires verification that the application current demand does not exceed 25mA per switch position. Applications operating at or below this threshold can proceed with direct substitution. Applications requiring the full 50mA capability of the original DPL12T must identify alternative solutions outside this substitute group.

Frequently Asked Questions (FAQ)

Q: Can the NDPL-12T-V be used as a direct replacement for the DPL12T in all applications?

A: Direct substitution is possible only if the application current requirement does not exceed 25mA per switch position. The NDPL-12T-V is rated for 25mA maximum, compared to the DPL12T's 50mA rating. Circuit analysis must confirm that the load current remains within this limit.

Q: Are the physical dimensions and mounting footprints identical?

A: Yes. Both parts share the same 0.100" (2.54mm) pitch, 0.402" (10.20mm) height above board, and through-hole right-angle mounting configuration. PCB layout modifications are not required.

Q: What is the difference in product status between these parts?

A: The DPL12T is classified as obsolete, while the NDPL-12T-V is an active product. The NDPL-12T-V represents the current manufacturing offering from APEM Inc. for this switch category and benefits from ongoing production support and availability.

Q: Are compliance certifications equivalent?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected. Moisture sensitivity level is identical at MSL 1 (unlimited). No compliance-related restrictions apply to substitution.

Q: What is the mechanical life difference?

A: The DPL12T specifies 5,000 mechanical cycles, while the NDPL-12T-V does not provide a published mechanical life specification. Both parts specify 2,000 electrical cycles. Application duty cycle requirements should be evaluated against available data.
