KSC323G Equivalent & Substitute Parts

Part Overview

The KSC323G is a tactile switch manufactured by C&K, classified as SPST-NO (Single Pole Single Throw - Normally Open) with a contact rating of 0.01A at 32VDC. This surface mount component features top actuation, gull wing termination, and IP67 ingress protection suitable for dust-tight and waterproof applications. The KSC323G is currently listed as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KSC323G is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: SPST-NO topology must be maintained
• Contact Rating: 0.01A @ 32VDC electrical specification
• Mounting Type: Surface mount requirement
• Actuator Geometry: 4.60mm vertical height, top actuation, 6.20mm x 6.20mm outline
• Termination: Gull wing leads for PCB compatibility
• Mechanical Characteristics: 200gf operating force, 0.20mm travel, 300,000 cycle life
• Environmental Rating: IP67 ingress protection
• Temperature Range: -40°C to 125°C operational limits

The KSC323GLFG meets all these parameters identically, establishing it as a direct functional equivalent. The primary distinction is packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The KSC323GLFG is the direct substitute for the obsolete KSC323G. Both components share identical electrical and mechanical specifications, ensuring functional interchangeability in circuit designs. The KSC323GLFG offers the following advantages:

• Active Product Status: Currently manufactured and supported by C&K, ensuring long-term availability and supply chain continuity
• RoHS3 Compliance: Meets current environmental and regulatory requirements, whereas the KSC323G is RoHS non-compliant
• Tape & Reel Packaging: Suitable for automated assembly processes, improving manufacturing efficiency compared to bulk packaging

Selection of KSC323GLFG eliminates obsolescence risk and aligns designs with current compliance standards while maintaining complete electrical and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Are KSC323G and KSC323GLFG electrically identical?

A: Yes. Both components feature SPST-NO configuration with 0.01A @ 32VDC contact rating, identical operating force (200gf), switch travel (0.20mm), and mechanical life (300,000 cycles).

Q: What is the primary difference between these parts?

A: The KSC323GLFG is packaged in Tape & Reel format and maintains active product status with ROHS3 compliance. The KSC323G is obsolete and supplied in bulk packaging with RoHS non-compliance.

Q: Can KSC323GLFG be used as a direct replacement on existing PCBs designed for KSC323G?

A: Yes. Identical outline dimensions (6.20mm x 6.20mm), actuator height (4.60mm), termination style (gull wing), and mounting type (surface mount) ensure direct PCB compatibility without layout modifications.

Q: Does packaging format affect component performance?

A: No. Tape & Reel and bulk packaging formats contain identical components. Packaging selection is determined by assembly process requirements and volume considerations.

Q: Are there environmental or temperature limitations when substituting KSC323GLFG for KSC323G?

A: No. Both components operate across -40°C to 125°C and maintain IP67 ingress protection across the full temperature range.
