CTS Electrocomponents 194-3MS DIP Switch Equivalent & Substitute Parts

Part Overview

The CTS Electrocomponents 194-3MS is a 3-position DIP switch with SPST circuit configuration, rated for 50mA at 24VDC. This through-hole, right-angle mounted component features a piano actuator and gold-plated contacts, designed for applications requiring reliable switching in industrial and commercial environments. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are identified when equivalent functional performance can be achieved within the allowed electrical and mechanical parameter ranges for DIP switch applications.

Key Parameters

Substitute Part Grouping Explanation

The Grayhill Inc. 76PSB03T qualifies as a substitute for the CTS 194-3MS based on the following alignment of critical parameters:

• Circuit Configuration: Both parts are SPST switches
• Position Count: Both provide 3-position switching
• Actuator Type: Both feature piano-type raised actuators
• Mounting Configuration: Both are through-hole, right-angle mounted
• Pitch Spacing: Both maintain 0.100" (2.54mm) pitch
• Contact Finish: Both utilize gold-plated contacts
• Operating Temperature: Both operate across -40°C to 85°C
• Compliance: Both are ROHS3 compliant with unlimited MSL rating

The 76PSB03T provides higher electrical ratings (150mA at 30VDC) compared to the 194-3MS (50mA at 24VDC), making it suitable for applications requiring greater current or voltage capacity while maintaining mechanical and functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the CTS 194-3MS and Grayhill 76PSB03T are active production components with full ROHS3 compliance and unlimited moisture sensitivity ratings, making either suitable for new designs and production environments.

The CTS 194-3MS is the primary choice when the application operates within 50mA at 24VDC specifications and when the higher electrical life rating of 7,000 cycles is required.

The Grayhill 76PSB03T serves as a substitute when higher current capacity (150mA) or voltage margin (30VDC) is needed, or when the 2,000-cycle electrical life rating is acceptable for the application. The mechanical dimensions are comparable, with negligible differences in height and length that do not impact standard PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can the Grayhill 76PSB03T directly replace the CTS 194-3MS in existing designs?

A: Yes, from a mechanical and functional standpoint. Both parts share identical circuit configuration (SPST), position count (3), actuator type (piano, raised), mounting method (through-hole, right-angle), and pitch spacing (0.100"). The height and length differences are minimal and do not affect standard PCB footprints. However, verify that your application does not depend on the specific electrical life rating of 7,000 cycles, as the 76PSB03T is rated for 2,000 cycles.

Q: What are the key differences between these two parts?

A: The primary differences are electrical ratings and cycle life. The 76PSB03T provides higher current capacity (150mA versus 50mA) and voltage rating (30VDC versus 24VDC), making it suitable for higher-power applications. The CTS 194-3MS offers superior electrical life (7,000 cycles versus 2,000 cycles), beneficial for high-frequency switching environments.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the CTS 194-3MS and Grayhill 76PSB03T are ROHS3 compliant, REACH unaffected, and carry unlimited moisture sensitivity ratings (MSL 1), making them suitable for current manufacturing and environmental requirements.

Q: Does the slight difference in physical dimensions affect PCB layout?

A: No. The height difference of 0.010" (0.25mm) and length difference of 0.006" (0.15mm) are within standard PCB design tolerances and do not require layout modifications for standard applications.

Q: Which part should I select for a new design?

A: Base your selection on your application's electrical requirements. If your circuit operates at or below 50mA and 24VDC with frequent switching cycles, the CTS 194-3MS is appropriate. If your application requires higher current or voltage capacity, or if cycle life is not a limiting factor, the Grayhill 76PSB03T is suitable.
