KAC04LGGT Equivalent & Substitute Parts

Part Overview

The KAC04LGGT is a 4-position DIP switch manufactured by E-Switch, featuring a piano actuator with SPST circuit configuration. This component is rated for 25mA at 24VDC and is designed for surface mount, right-angle applications. The part maintains Active product status and is RoHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent functional performance can be achieved within the allowed electrical and mechanical parameter ranges for DIP switch applications, particularly when original inventory is unavailable or when alternative actuator types and contact materials meet application requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the KAC04LGGT is determined by the following critical parameters:

Core Functional Requirements:

Circuit configuration: SPST (Single Pole, Single Throw)
Number of positions: 4
Mounting type: Surface Mount with Gull Wing termination
Pitch spacing: 0.100" (2.54mm)
Voltage rating: 24VDC or higher
Current rating: 25mA or higher

Allowed Variations:

Actuator type: Piano or Slide (Standard) actuators are functionally equivalent for SPST DIP switch applications
Contact material: Gold-plated contacts on Beryllium Copper or equivalent materials maintain electrical performance
Height above board: Variations within 0.170" to 0.201" are acceptable for surface mount applications
Operating temperature range: Minimum -20°C and maximum 85°C or broader
Mechanical life: 2,000 cycles or higher

The identified substitutes meet these criteria while maintaining SPST 4-position configuration, surface mount gull wing termination, and gold contact finish specifications.

Engineering Selection Recommendations

219-4MSTRF (CTS Electrocomponents): This substitute provides higher current capacity (100mA versus 25mA) and extended low-temperature operating range (-55°C). However, the voltage rating is 20VDC, which is below the KAC04LGGT specification of 24VDC. This part is suitable only for applications operating at 20VDC or lower. The slide actuator differs from the piano actuator of the original part. RoHS3 compliance and MSL 1 rating are maintained.

JS0204AP4 (NKK Switches): This substitute maintains identical electrical specifications (25mA at 24VDC) and mechanical life rating (2,000 cycles). The slide actuator replaces the piano actuator, and the height above board is reduced to 0.170". The operating temperature range is -20°C to 70°C, which is narrower than the original part at the upper limit (70°C versus 85°C). RoHS3 compliance and MSL 1 rating are maintained. This part is directly compatible for applications within the -20°C to 70°C temperature window.

Both substitutes maintain ROHS3 compliance, REACH unaffected status, and unlimited moisture sensitivity rating. Product status is Active for all three parts.

Frequently Asked Questions (FAQ)

Q: Can the 219-4MSTRF be used in a 24VDC application? A: No. The 219-4MSTRF is rated for 20VDC maximum. Using this part in a 24VDC circuit exceeds its voltage specification and is not permitted.

Q: What is the functional difference between piano and slide actuators in DIP switches? A: Both actuator types perform the same SPST switching function. The piano actuator uses a raised lever mechanism, while the slide actuator uses a sliding toggle. The electrical performance and switching characteristics are equivalent for SPST applications.

Q: Is the JS0204AP4 suitable for applications requiring operation above 70°C? A: No. The JS0204AP4 operating temperature range is -20°C to 70°C. The KAC04LGGT supports operation to 85°C. For applications requiring temperatures between 70°C and 85°C, the JS0204AP4 is not suitable.

Q: Are all three parts RoHS3 compliant? A: Yes. The KAC04LGGT, 219-4MSTRF, and JS0204AP4 are all RoHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating.

Q: Does the difference in height above board affect PCB layout compatibility? A: The KAC04LGGT has a height of 0.201" (5.10mm), while both substitutes measure 0.170" (4.33mm). This 0.031" difference must be evaluated against PCB clearance requirements and component placement constraints in the specific application.

Q: What is the pitch specification and is it consistent across all parts? A: All three parts maintain a 0.100" (2.54mm) full pitch spacing, ensuring consistent footprint compatibility for the 4-position configuration.
