DPL05T Equivalent & Substitute Parts

Part Overview

The DPL05T is a piano-type DIP switch manufactured by APEM Inc., configured as a 5-position SPST (Single Pole Single Throw) through-hole component rated for 50mA at 24VDC. This part is classified as obsolete, making identification of suitable alternatives necessary for ongoing design support and production continuity. The component features a raised piano actuator, gold-plated phosphor bronze contacts, and is sealed with epoxy terminals and tape seal for environmental protection.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DPL05T is determined by the following critical parameters:

• Circuit Configuration: Must be SPST
• Number of Positions: Must be 5
• Voltage Rating: Must be 24VDC
• Actuator Type: Must be Piano with Raised level
• Mounting Type: Must be Through Hole, Right Angle
• Pitch: Must be 0.100" (2.54mm)
• Height Above Board: Must be 0.402" (10.20mm)
• Contact Finish: Must be Gold
• Operating Temperature Range: Must support -20°C to 70°C
• RoHS Compliance: Must be ROHS3 Compliant

The NDPL-05T-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 design constraint that must be evaluated against actual circuit requirements. The NDPL-05T-V maintains identical mechanical dimensions, electrical configuration, environmental sealing, and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The NDPL-05T-V is the qualified substitute for the obsolete DPL05T. Both components are manufactured by APEM Inc. and maintain identical mechanical and electrical interface specifications. The NDPL-05T-V carries Active product status, ensuring continued availability and supply chain support.

Selection of the NDPL-05T-V requires verification that circuit current requirements do not exceed 25mA. If the application demands the full 50mA current capacity of the original DPL05T, the NDPL-05T-V is not suitable. In such cases, alternative component families from APEM Inc. or other manufacturers meeting the 50mA specification at 24VDC with identical mechanical form factor must be evaluated.

Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating, supporting deployment in standard industrial and commercial environments within the specified temperature range.

Frequently Asked Questions (FAQ)

Q: Can the NDPL-05T-V be used as a direct replacement for the DPL05T?

A: The NDPL-05T-V is mechanically and electrically compatible with the DPL05T for all interface parameters. However, the reduced current rating of 25mA versus 50mA must be confirmed as acceptable for the specific application before substitution.

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

A: The current rating differs: DPL05T is rated for 50mA, while NDPL-05T-V is rated for 25mA. All other specifications, including voltage, configuration, dimensions, and environmental ratings, are identical.

Q: Are both parts RoHS compliant?

A: Yes, both the DPL05T and NDPL-05T-V are ROHS3 compliant and suitable for applications requiring RoHS certification.

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

A: Both components feature a 0.100" (2.54mm) pitch, which is the standard spacing for through-hole DIP switch arrays.

Q: Can these parts be used in high-temperature applications?

A: Both components are rated for operation from -20°C to 70°C. Applications requiring operation outside this range require alternative component selection.

Q: Are there any differences in mechanical life between these parts?

A: The DPL05T specifies 5,000 mechanical cycles. The NDPL-05T-V does not provide a mechanical life specification in the available data. Both specify 2,000 electrical cycles.
