BP10YT DIP Switch SPST 10 Position Equivalent & Substitute Parts

Part Overview

The BP10YT is a slide-actuated DIP switch manufactured by C&K, configured as a single-pole single-throw (SPST) switch with 10 positions. It is rated for 100mA at 5VDC and designed for through-hole, right-angle mounting with PC pin termination. The BP10YT is currently listed as obsolete, making identification of functionally equivalent substitute parts essential for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BP10YT must maintain the following core electrical and mechanical parameters:

• Circuit configuration: SPST
• Number of positions: 10
• Mounting type: Through hole, right angle
• Pitch: 0.100" (2.54mm)
• Termination style: PC pin
• Washable design: Yes

Current rating and voltage rating define the electrical operating envelope. Substitute parts may differ in actuator type (slide versus piano), contact material, contact finish, and body material, provided the electrical ratings meet or exceed the application requirements. Operating temperature range and product status (active versus obsolete) are secondary considerations for component selection.

Parameter Comparison

Engineering Selection Recommendations

BPA10B (C&K) is the primary substitute for BP10YT. Both parts are manufactured by C&K, share identical electrical ratings (100mA, 5VDC), and maintain the same 10-position SPST configuration with 0.100" pitch and PC pin termination. The BPA10B features a piano actuator instead of a slide actuator and is constructed with polyphenylene sulfide (PPS) body material and beryllium copper contacts with gold finish. The BPA10B is currently in active production status and carries ROHS3 compliance certification. Operating temperature range extends to 85°C, providing improved thermal margin over the obsolete BP10YT.

195-10MST (CTS Electrocomponents) is a secondary substitute option. This part maintains the 10-position SPST configuration, through-hole right-angle mounting, 0.100" pitch, and PC pin termination. However, the 195-10MST is rated for 50mA at 24VDC, which differs from the BP10YT electrical envelope. This part is suitable only for applications where the lower current rating (50mA) and higher voltage rating (24VDC) are compatible with the circuit design. The 195-10MST is in active production and carries ROHS3 compliance certification.

Frequently Asked Questions (FAQ)

Q: Can BPA10B directly replace BP10YT in existing designs?

A: BPA10B maintains electrical compatibility (100mA, 5VDC, SPST, 10 positions) and mechanical compatibility (through-hole right angle, 0.100" pitch, PC pin termination). The primary difference is actuator type: BPA10B uses a piano actuator versus the slide actuator on BP10YT. Physical height above board differs by 0.028" (0.70mm). PCB layout and mechanical clearance must be verified before substitution.

Q: Is 195-10MST suitable for 5VDC applications?

A: 195-10MST is rated for 24VDC operation. While the part will function at 5VDC from an electrical standpoint, the current rating is limited to 50mA, compared to 100mA for BP10YT and BPA10B. Substitution is valid only if the application circuit operates at or below 50mA.

Q: What is the difference between slide and piano actuators?

A: Slide actuators (BP10YT) use a linear sliding motion for position selection. Piano actuators (BPA10B, 195-10MST) use individual push-button mechanisms for each position. Actuator type affects user interface, mechanical feel, and physical profile. Selection depends on application requirements and PCB layout constraints.

Q: Are all three parts RoHS compliant?

A: BP10YT carries RoHS Compliant certification. BPA10B and 195-10MST carry ROHS3 Compliant certification, which represents a more recent regulatory standard. All three parts are REACH Unaffected and carry EAR99 export classification.

Q: What is the packaging format for each part?

A: BP10YT is supplied with standard packaging (not specified). BPA10B and 195-10MST are supplied in tube packaging, which is standard for DIP switch components and facilitates automated assembly processes.
