CTS Electrocomponents 194-10MST DIP Switch Equivalent & Substitute Parts

Part Overview

The CTS Electrocomponents 194-10MST is a 10-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.

Equivalent and substitute parts are identified when design requirements allow for higher electrical ratings, alternative mechanical configurations, or when primary inventory is unavailable while maintaining functional compatibility within specified operating parameters.

Key Parameters

Substitute Part Grouping Explanation

The Grayhill Inc. 76PSB10ST qualifies as a functional substitute for the 194-10MST based on the following alignment of critical parameters:

Matching Parameters:

• SPST circuit configuration
• 10-position switch array
• Piano actuator with raised level
• Through-hole, right-angle mounting
• 0.100" (2.54mm) pitch spacing
• Gold-plated contacts
• Operating temperature range: -40°C to 85°C
• RoHS3 compliance
• Unlimited moisture sensitivity (MSL 1)

Elevated Electrical Ratings: The 76PSB10ST provides higher current capacity (150mA versus 50mA) and voltage rating (30VDC versus 24VDC), making it suitable for applications where the 194-10MST specifications are met or exceeded by the design requirements.

Parameter Comparison

Engineering Selection Recommendations

The 76PSB10ST from Grayhill Inc. is a valid substitute for the 194-10MST when design specifications permit operation at the higher electrical ratings. Both components maintain ROHS3 compliance and identical moisture sensitivity classification, ensuring regulatory and environmental compatibility.

Selection between these parts should be based on:

• Circuit current requirements: The 194-10MST is suitable for applications up to 50mA; the 76PSB10ST accommodates up to 150mA
• Circuit voltage requirements: The 194-10MST operates at 24VDC maximum; the 76PSB10ST at 30VDC maximum
• Physical space constraints: The 76PSB10ST has marginally reduced height (0.010" lower) and length (0.006" shorter), which may be advantageous in compact layouts
• Inventory availability: Both parts are currently in active production with stock availability

Frequently Asked Questions (FAQ)

Q: Can the 76PSB10ST replace the 194-10MST in a 24VDC, 50mA application?

A: Yes. The 76PSB10ST is rated for 30VDC and 150mA, exceeding the 194-10MST specifications. It will function correctly in applications designed for the lower ratings.

Q: Are the mechanical dimensions compatible for PCB mounting?

A: The pitch spacing (0.100" / 2.54mm) is identical, ensuring compatible PCB footprints. The 76PSB10ST is marginally smaller in height and length, which does not affect mounting compatibility but may provide layout advantages.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the 194-10MST and 76PSB10ST are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating, meeting identical environmental and regulatory standards.

Q: What is the difference in electrical life between these parts?

A: The 194-10MST is rated for 7,000 electrical cycles. The 76PSB10ST is rated for 2,000 electrical cycles. Application duty cycle requirements should be evaluated when selecting between these parts.

Q: Are the contact materials different?

A: The 194-10MST contact material is not specified in the data provided. The 76PSB10ST uses copper alloy contacts with gold plating. Both feature gold contact finish.
