BP07YT DIP Switch SPST 7 Position Equivalent & Substitute Parts

Part Overview

The BP07YT is a slide-actuated DIP switch manufactured by C&K, configured as a single-pole single-throw (SPST) switch with 7 positions. This component is rated for 100mA at 5VDC and features through-hole, right-angle mounting with PC pin termination. The BP07YT is currently classified as obsolete, making identification of functionally equivalent substitute components necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BP07YT is determined by the following critical parameters:

• Circuit Configuration: Must be SPST to maintain single-switch functionality
• Number of Positions: Must be 7 to match the multi-position switching capability
• Mounting Type & Pitch: Must be through-hole, right-angle with 0.100" (2.54mm) pitch to ensure PCB compatibility
• Termination Style: Must be PC pin for direct board insertion
• Electrical Characteristics: Current and voltage ratings must meet or exceed the application requirements

The CTS Electrocomponents 195-7MST satisfies these core substitution criteria. While it features a piano actuator instead of a slide actuator and operates at a higher voltage rating (24VDC vs. 5VDC), it maintains identical circuit configuration, position count, mounting geometry, and pitch specifications. The higher voltage rating provides design flexibility for applications operating at elevated supply voltages.

Parameter Comparison

Engineering Selection Recommendations

The 195-7MST is an active product with current manufacturing support, whereas the BP07YT is obsolete. Both components are RoHS compliant and REACH unaffected, meeting modern regulatory requirements.

The 195-7MST provides extended operating temperature range (-40°C to 85°C vs. -20°C to 60°C) and increased electrical life (2,000 cycles vs. 1,000 cycles), offering improved reliability margins for long-term applications. The piano actuator differs mechanically from the slide actuator, requiring user interface evaluation for specific applications.

Current rating consideration: The 195-7MST is rated at 50mA, which is lower than the BP07YT's 100mA rating. Applications requiring currents exceeding 50mA must verify alternative substitutes or confirm that actual circuit current demands remain within the 195-7MST specification.

Frequently Asked Questions (FAQ)

Q: Can the 195-7MST directly replace the BP07YT in existing designs?

A: Mechanical and electrical compatibility is confirmed for the core switching function. The pitch, mounting type, and termination style are identical. However, the actuator type differs (piano vs. slide), which may affect user interaction and panel layout. Verify that the 50mA current rating is sufficient for your application.

Q: What is the significance of the voltage rating difference (5VDC vs. 24VDC)?

A: The 195-7MST's higher voltage rating indicates it can safely operate at elevated supply voltages. For applications using 5VDC, the 195-7MST operates well within its rated specification. The voltage rating does not limit operation at lower voltages.

Q: Are there any compliance differences between these parts?

A: Both components are RoHS compliant and REACH unaffected. The 195-7MST carries ROHS3 certification, representing the current RoHS standard revision. Both meet EAR99 export classification.

Q: How do the actuator types affect substitution?

A: The slide actuator (BP07YT) and piano actuator (195-7MST) provide different mechanical interfaces. Slide actuators typically require linear motion along the switch axis, while piano actuators use a rocker mechanism. Panel cutout geometry and user interface design must accommodate the selected actuator type.

Q: What should be verified before implementing the 195-7MST as a substitute?

A: Confirm that circuit current requirements do not exceed 50mA. Verify that the piano actuator's mechanical interface is compatible with the intended application's user interaction model. Validate that the extended operating temperature range (-40°C to 85°C) meets or exceeds application requirements.
