DP08T DIP Switch Equivalent & Substitute Parts

Part Overview

The DP08T is an 8-position DIP switch manufactured by APEM Inc., designed for through-hole, right-angle mounting applications requiring low-current switching at 24VDC. This component features a piano actuator with flush, recessed actuation and gold-plated phosphor bronze contacts. The DP08T 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 DP08T is determined by the following critical parameters:

• Circuit Configuration: Must be SPST to maintain single-pole switching functionality
• Number of Positions: Must be 8 to ensure PCB layout compatibility
• Voltage Rating: Must be rated for 24VDC operation
• Mounting Type: Must be through-hole, right-angle to fit existing board footprints
• Pitch: Must maintain 0.100" (2.54mm) spacing for PCB pad alignment
• Actuator Type: Must be piano actuator for consistent user interface
• Height Above Board: Must be within tolerance of 0.402" (10.20mm) to avoid mechanical interference

The NDP-08T-V meets all critical substitution criteria. The primary difference is a reduced current rating of 25mA versus the original 50mA specification. This reduction is acceptable in applications where the circuit current demand does not exceed 25mA.

Parameter Comparison

Engineering Selection Recommendations

The NDP-08T-V is a direct functional substitute for the DP08T in applications where circuit current does not exceed 25mA. Both components maintain identical mechanical footprints, electrical interfaces, and environmental ratings. The NDP-08T-V offers the advantage of active product status, ensuring continued availability and manufacturing support. Both parts carry ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement.

Selection of the NDP-08T-V is appropriate for new designs and legacy system updates where the reduced current rating aligns with circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can the NDP-08T-V replace the DP08T in existing designs?

A: Yes, provided the circuit current does not exceed 25mA. The mechanical footprint, mounting configuration, and electrical interface are identical. The primary difference is the current rating reduction from 50mA to 25mA.

Q: Are the PCB footprints identical between DP08T and NDP-08T-V?

A: Yes. Both components use 0.100" (2.54mm) pitch, through-hole PC pin termination, and 0.402" (10.20mm) height above board. No PCB layout modifications are required.

Q: What is the significance of the DP08T being obsolete?

A: Obsolete status indicates the DP08T is no longer manufactured. The NDP-08T-V, classified as active, is the current production equivalent and is recommended for new procurement and design implementations.

Q: Are there any compliance differences between the two parts?

A: No. Both the DP08T and NDP-08T-V are ROHS3 compliant, REACH unaffected, and carry identical MSL ratings of 1 (Unlimited).

Q: What is the maximum current the NDP-08T-V can safely switch?

A: The NDP-08T-V is rated for 25mA maximum continuous current at 24VDC. Applications requiring higher current switching should retain the DP08T specification or identify alternative components with higher current ratings.
