DP09T DIP Switch Equivalent & Substitute Parts

Part Overview

The DP09T is a 9-position DIP switch manufactured by APEM Inc., configured as a single-pole single-throw (SPST) switch with piano actuator. This component is rated for 50mA at 24VDC and features through-hole, right-angle mounting with gold-plated phosphor bronze contacts. The DP09T is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DP09T is determined by the following critical parameters:

• Circuit configuration (SPST)
• Number of positions (9)
• Voltage rating (24VDC)
• Actuator type (Piano)
• Mounting type (Through Hole, Right Angle)
• Pitch spacing (0.100" / 2.54mm)
• Height above board (0.402" / 10.20mm)
• Contact finish (Gold)
• Operating temperature range (-20°C to 70°C)
• RoHS3 compliance

The NDP-09T-V meets all critical mechanical and electrical compatibility criteria. The primary difference is a reduced current rating of 25mA versus the original 50mA specification. This substitute is suitable for applications where the lower current rating satisfies system requirements.

Parameter Comparison

Engineering Selection Recommendations

The NDP-09T-V is an active product from APEM Inc. and maintains full mechanical and electrical compatibility with the DP09T across all critical interface parameters. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Selection of the NDP-09T-V as a substitute requires verification that the application current demand does not exceed 25mA. For applications requiring the full 50mA current capacity of the original DP09T, alternative substitutes within the APEM DIP switch portfolio should be evaluated.

The NDP-09T-V is available in active inventory status, providing supply chain continuity for the obsolete DP09T.

Frequently Asked Questions (FAQ)

Q: Can the NDP-09T-V directly replace the DP09T in existing designs?

A: The NDP-09T-V is mechanically and electrically compatible with the DP09T for all interface parameters including mounting, pitch, height, and voltage rating. Substitution is valid provided the application current requirement does not exceed 25mA.

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

A: The current rating differs: DP09T is rated for 50mA while NDP-09T-V is rated for 25mA. All other electrical and mechanical specifications are equivalent.

Q: Are both parts RoHS compliant?

A: Yes, both the DP09T and NDP-09T-V are ROHS3 compliant and REACH unaffected.

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

A: Both components use 0.100" (2.54mm) pitch spacing, standard for 9-position DIP switch configurations.

Q: Can I use the NDP-09T-V in a high-current application originally designed for the DP09T?

A: No. If the application requires current handling above 25mA, the NDP-09T-V is not suitable. The original DP09T specification of 50mA must be maintained.

Q: What is the operating temperature range for these switches?

A: Both components operate across -20°C to 70°C, providing equivalent thermal performance.
