Key Parameters

Substitute Part Grouping Explanation

Substitution of the KSC411G 70 SH is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: SPST-NO topology must be maintained
• Electrical Rating: Contact rating of 0.05A @ 32VDC is mandatory
• Physical Dimensions: Outline of 6.20mm x 6.20mm and actuator height of 5.20mm ensure PCB layout compatibility
• Mounting and Termination: Surface mount with gull wing termination required for assembly process compatibility
• Actuator Characteristics: Top actuation, 140gf operating force, and 0.35mm switch travel must be preserved
• Environmental Specifications: IP67 ingress protection and -40°C to 85°C operating temperature range must be maintained
• Mechanical Durability: 1,000,000 cycle mechanical life specification must be met

The identified substitute maintains all electrical, mechanical, and environmental parameters while differing only in product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The KSC411G 70SH LFS is the direct functional equivalent of the KSC411G 70 SH. Both components are manufactured by C&K within the KSC series and maintain identical electrical, mechanical, and environmental specifications. The primary distinctions are:

Product Status: The KSC411G 70SH LFS carries Active status, ensuring continued availability and manufacturer support, whereas the original part is Obsolete.

Regulatory Compliance: The KSC411G 70SH LFS is ROHS3 compliant, meeting current environmental regulations. The original part is RoHS non-compliant.

Packaging Configuration: The substitute is supplied in Tape & Reel (TR) format, optimized for automated assembly processes, compared to bulk packaging of the original.

For new designs, production continuity, and regulatory compliance requirements, the KSC411G 70SH LFS is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Are the KSC411G 70 SH and KSC411G 70SH LFS electrically identical?

A: Yes. Both components feature SPST-NO configuration with 0.05A @ 32VDC contact rating, identical actuator specifications (140gf operating force, 0.35mm travel), and equivalent environmental ratings (IP67, -40°C to 85°C).

Q: What is the significance of the "LFS" designation in the substitute part number?

A: The "LFS" suffix indicates the part is supplied in Tape & Reel packaging format, suitable for automated pick-and-place assembly. This differs from the bulk packaging of the original part.

Q: Can the KSC411G 70SH LFS be used as a direct replacement in existing PCB designs?

A: Yes. The substitute maintains identical physical dimensions (6.20mm x 6.20mm outline, 5.20mm actuator height), gull wing termination, and top actuation orientation, ensuring compatibility with existing PCB layouts and assembly processes.

Q: Why is RoHS3 compliance important for the substitute part?

A: ROHS3 compliance ensures the component meets current environmental and hazardous substance restrictions mandated in many markets. The original part's RoHS non-compliant status may restrict its use in regulated applications and future procurement.

Q: Is there a difference in mechanical performance between the two parts?

A: No. Both components specify 1,000,000 cycle mechanical life and identical switch travel characteristics, ensuring equivalent durability and performance in tactile switch applications.
