CTS Electrocomponents 194-4MS DIP Switch Equivalent & Substitute Parts

Part Overview

The CTS Electrocomponents 194-4MS is a 4-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 may be required due to inventory constraints, end-of-life considerations, or application-specific performance requirements that exceed the original specification.

Key Parameters

Substitute Part Grouping Explanation

The Grayhill Inc. 76PSB04T qualifies as a functional substitute for the 194-4MS based on the following critical parameters:

Matching Parameters:

• SPST circuit configuration
• 4-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 rating (MSL 1)

Exceeding Parameters:

• Current rating: 150mA (vs. 50mA original)
• Voltage rating: 30VDC (vs. 24VDC original)

The 76PSB04T provides higher electrical ratings while maintaining mechanical and environmental compatibility, making it suitable for applications where the original specification is met or where increased headroom is beneficial.

Parameter Comparison

Engineering Selection Recommendations

Both the 194-4MS and 76PSB04T are active production components with full RoHS3 compliance and REACH unaffected status. The 194-4MS offers superior electrical life cycling (7,000 cycles vs. 2,000 cycles), making it preferable for high-cycle switching applications. The 76PSB04T provides elevated current and voltage ratings, suitable for applications requiring operational margin above the original 50mA/24VDC specification. Mechanical compatibility is confirmed through matching pitch, mounting style, and actuator configuration. Selection should be based on application cycle requirements and electrical load specifications.

Frequently Asked Questions (FAQ)

Q: Can the 76PSB04T directly replace the 194-4MS in existing designs?

A: Yes, from a mechanical and environmental standpoint. The 0.100" pitch, through-hole right-angle mounting, and identical actuator configuration ensure PCB compatibility. Electrical compatibility is confirmed for applications operating at or below 50mA and 24VDC. Applications requiring the full 150mA/30VDC capability of the 76PSB04T will operate within specification.

Q: What is the primary difference between these two parts?

A: The 76PSB04T provides higher electrical ratings (150mA at 30VDC vs. 50mA at 24VDC) but has reduced electrical life (2,000 cycles vs. 7,000 cycles). The 194-4MS is optimized for extended-cycle applications, while the 76PSB04T offers higher power handling capacity.

Q: Are there any physical dimension concerns when substituting?

A: Dimensions are nearly identical. The 76PSB04T is marginally shorter (0.480" vs. 0.486" length) and slightly lower above board (0.301" vs. 0.311" height). These differences are negligible for standard PCB layouts and do not affect functionality or clearance in typical applications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are RoHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity ratings. Environmental and regulatory requirements are equivalent.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. For high-cycle switching (>2,000 cycles), the 194-4MS is recommended. For applications requiring higher electrical margins or where load specifications exceed 50mA/24VDC, the 76PSB04T is appropriate. Both are active production parts suitable for new designs.
