DPL08T Equivalent & Substitute Parts

Part Overview

The DPL08T is an 8-position DIP switch manufactured by APEM Inc., configured as a single-pole single-throw (SPST) through-hole component with piano actuator. This switch is rated for 50mA at 24VDC and features phosphor bronze contacts with gold finish, designed for applications requiring reliable switching in industrial and control systems. The DPL08T is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DPL08T is determined by the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration (SPST)
• Number of positions (8)
• Voltage rating (24VDC)
• Actuator type (Piano)
• Mounting type (Through Hole, Right Angle)
• Pitch (0.100" / 2.54mm)
• Contact finish (Gold)
• Operating temperature range (-20°C to 70°C)

Allowable Variation Parameters:

• Current rating: Substitutes must meet or exceed the application requirement; lower current ratings are acceptable only if the application current demand does not exceed the substitute's rating
• Mechanical and electrical life specifications: Variations permitted based on application cycle requirements
• Contact material composition: Variations permitted if electrical performance is maintained
• Body material specifications: Variations permitted if mechanical and environmental performance is maintained

The NDPL-08T-V qualifies as a substitute based on matching all mandatory parameters. However, the current rating differential (25mA vs. 50mA) requires application-level verification to ensure the substitute's current capacity is sufficient for the intended circuit.

Parameter Comparison

Engineering Selection Recommendations

The NDPL-08T-V is an active production substitute for the obsolete DPL08T. Both components are manufactured by APEM Inc. and maintain identical mechanical form factors, electrical configurations, and regulatory compliance certifications (ROHS3, REACH Unaffected, EAR99).

The primary distinction between these components is the current rating specification: the DPL08T is rated for 50mA, while the NDPL-08T-V is rated for 25mA. Selection between these components depends on the actual current requirements of the application circuit. If the application circuit operates at or below 25mA, the NDPL-08T-V provides a direct functional replacement with the advantage of active product status and current inventory availability. If the application circuit requires current capacity exceeding 25mA, the DPL08T specifications must be maintained or alternative components with higher current ratings must be evaluated.

Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Frequently Asked Questions (FAQ)

Q: Can the NDPL-08T-V directly replace the DPL08T in all applications?

A: Direct replacement is possible only if the application circuit current does not exceed 25mA. The NDPL-08T-V is rated for 25mA maximum, compared to the DPL08T's 50mA rating. Verify the actual circuit current requirement before substitution.

Q: Why is the DPL08T classified as obsolete?

A: The DPL08T has been discontinued by APEM Inc. The NDPL-08T-V represents the active production alternative within the APEM DIP switch product line.

Q: Are the mechanical dimensions identical between DPL08T and NDPL-08T-V?

A: Yes. Both components share identical height above board (0.402" / 10.20mm), pitch (0.100" / 2.54mm), mounting type (through hole, right angle), and termination style (PC pin). Length specifications differ slightly (0.861" vs. 0.850"), but this variation does not affect PCB layout compatibility.

Q: Do both components meet current regulatory compliance requirements?

A: Yes. Both the DPL08T and NDPL-08T-V are ROHS3 compliant and REACH unaffected, meeting current electronic component regulatory standards.

Q: What is the difference in contact material between these components?

A: The DPL08T specifies phosphor bronze contacts with gold finish. The NDPL-08T-V contact material is not specified in available documentation but maintains gold finish. Both components are rated for identical voltage (24VDC) and electrical life (2,000 cycles).

Q: Are there differences in mechanical life between these components?

A: The DPL08T specifies 5,000 mechanical cycles. The NDPL-08T-V mechanical life specification is not provided in available documentation. Electrical life is identical at 2,000 cycles for both components.
