KSL0M410 Equivalent & Substitute Parts

Part Overview

The KSL0M410 is a tactile switch manufactured by C&K, featuring SPST-NO (Single Pole Single Throw - Normally Open) circuit configuration with a contact rating of 0.05A at 32VDC. This component is designed for through-hole mounting with top actuation and operates across a temperature range of -40°C to 90°C. The product is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KSL0M410 is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO to maintain identical electrical behavior
• Switch Function: Must be Off-Mom (momentary) operation
• Contact Rating: Minimum 0.05A at operating voltage; voltage rating must support 32VDC application requirements
• Mounting Type: Must be through-hole to ensure PCB compatibility
• Actuator Orientation: Must be top-actuated for mechanical fit
• Termination Style: Must use PC Pin termination for connector compatibility
• Outline Dimensions: Footprint tolerance of ±0.20mm acceptable for PCB layout
• Actuator Height: Vertical clearance tolerance of ±0.10mm acceptable
• Operating Force: 300gf ±50gf acceptable range
• Switch Travel: 0.60mm ±0.10mm acceptable range
• Operating Temperature: Must support minimum -40°C to 85°C range
• Mechanical Life: Minimum 100,000 cycles required

The TL6100DF300QP from E-Switch meets these substitution criteria with compatible electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The TL6100DF300QP serves as a direct functional equivalent to the obsolete KSL0M410. Selection of this substitute is supported by the following factors:

Electrical Compatibility: Both components share identical circuit configuration (SPST-NO), switch function (Off-Mom), and contact current rating (0.05A). The TL6100DF300QP is rated for 12VDC operation, which is suitable for applications operating at or below this voltage. For applications requiring the full 32VDC rating of the original KSL0M410, voltage derating analysis is required.

Mechanical Compatibility: Outline dimensions, actuator height, operating force, and switch travel fall within acceptable tolerance ranges for PCB layout and mechanical assembly. The substitute component provides 500,000 mechanical cycles compared to the original 100,000 cycles, exceeding reliability requirements.

Compliance Status: The TL6100DF300QP is ROHS3 compliant and REACH unaffected, offering improved regulatory compliance compared to the RoHS non-compliant KSL0M410. Both components carry MSL 1 (Unlimited) moisture sensitivity classification.

Product Status: The TL6100DF300QP is classified as active product with 4,600 units in stock, ensuring long-term availability compared to the obsolete status of the KSL0M410.

Frequently Asked Questions (FAQ)

Q: Can the TL6100DF300QP replace the KSL0M410 in all applications?

A: The TL6100DF300QP is mechanically and electrically compatible for applications operating at 12VDC or lower. For applications requiring the full 32VDC rating of the original component, voltage derating analysis must be performed to confirm suitability.

Q: What are the dimensional differences between these components?

A: The TL6100DF300QP has a slightly smaller outline (7.20mm x 7.20mm versus 7.40mm x 7.40mm) and marginally taller actuator height (10.00mm versus 9.90mm). These differences are within standard PCB layout tolerances and do not affect mechanical fit for standard through-hole applications.

Q: How do the mechanical life ratings compare?

A: The KSL0M410 is rated for 100,000 mechanical cycles, while the TL6100DF300QP is rated for 500,000 cycles. The substitute component exceeds the original specification, providing extended operational life.

Q: Are there compliance differences between these components?

A: The TL6100DF300QP is ROHS3 compliant, whereas the KSL0M410 is RoHS non-compliant. Both components are REACH unaffected and carry MSL 1 moisture sensitivity classification. The substitute offers improved regulatory compliance for new designs.

Q: What is the operating temperature range difference?

A: The KSL0M410 operates from -40°C to 90°C, while the TL6100DF300QP operates from -40°C to 85°C. The substitute covers the lower temperature extreme identically and operates to 85°C, which is suitable for most industrial applications. Applications requiring operation above 85°C require alternative component selection.

Q: How do the switch travel specifications compare?

A: The KSL0M410 has 0.60mm switch travel, while the TL6100DF300QP has 0.50mm travel. This 0.10mm difference is within standard mechanical tolerance and does not affect tactile feedback or functional performance in typical applications.
