DP07T DIP Switch Piano Actuator Equivalent & Substitute Parts

Part Overview

The DP07T is a 7-position DIP switch manufactured by APEM Inc., featuring a piano actuator mechanism with SPST (Single Pole Single Throw) circuit configuration. Rated for 50mA at 24VDC, this component is designed for through-hole, right-angle mounting applications with gold-plated phosphor bronze contacts. The DP07T is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DP07T is determined by the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: SPST
• Number of positions: 7
• Voltage rating: 24VDC
• Actuator type: Piano
• Mounting type: Through Hole, Right Angle
• Pitch: 0.100" (2.54mm)
• Height above board: 0.402" (10.20mm)

Allowable Variation Parameters:

• Current rating: May be lower than 50mA if application requirements permit
• Product status: Active parts are preferred for obsolete replacements
• Contact material and finish specifications
• Mechanical life cycles
• Body material composition

The NDP-07T-V meets all mandatory matching parameters and qualifies as a direct substitute. The primary difference is a reduced current rating of 25mA compared to the original 50mA specification, which is acceptable for applications operating within the lower current envelope.

Parameter Comparison

Engineering Selection Recommendations

The NDP-07T-V is the qualified substitute for the obsolete DP07T. Both components maintain identical mechanical and electrical interface specifications, ensuring direct PCB compatibility without layout modifications.

Selection of the NDP-07T-V is supported by:

• Active product status, ensuring long-term availability and supply chain continuity
• ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements
• Identical operating temperature range and electrical life cycle rating
• Matching actuator geometry and mounting footprint
• Gold-plated contact finish for reliable signal integrity

The reduced current rating of 25mA in the NDP-07T-V requires verification that application circuit loads do not exceed this specification. For applications requiring the full 50mA current capacity of the original DP07T, alternative active DIP switch models with matching mechanical specifications and higher current ratings must be evaluated.

Frequently Asked Questions (FAQ)

Q: Can the NDP-07T-V be used as a direct replacement for the DP07T without PCB modifications?

A: Yes. Both components share identical pitch (0.100"), height above board (0.402"), mounting type (through-hole right angle), and termination style (PC pin). No PCB layout changes are required.

Q: What is the primary difference between the DP07T and NDP-07T-V?

A: The NDP-07T-V has a reduced current rating of 25mA compared to the DP07T's 50mA specification. The NDP-07T-V is also an active product, whereas the DP07T is obsolete.

Q: Is the NDP-07T-V suitable for all applications using the DP07T?

A: The NDP-07T-V is suitable only for applications where the circuit current does not exceed 25mA. Applications requiring higher current capacity must identify alternative substitute parts with matching mechanical specifications and appropriate current ratings.

Q: Are there compliance or regulatory differences between these parts?

A: Both components are ROHS3 compliant and REACH unaffected. No regulatory barriers exist to substitution.

Q: What is the mechanical life difference between these parts?

A: The DP07T specifies 5,000 mechanical cycles. The NDP-07T-V does not provide a mechanical life specification in available documentation. Both specify 2,000 electrical life cycles.
