KSC343G Equivalent & Substitute Parts

Part Overview

The KSC343G 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 KSC343G 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 KSC343G is determined by strict equivalence across electrical and mechanical parameters. The following criteria establish direct substitutability:

• Circuit configuration must remain SPST-NO
• Contact rating must match 0.01A @ 32VDC
• Mounting type must be Surface Mount
• Actuator height must be 4.60mm vertical
• Actuator orientation must be Top Actuated
• Termination style must be Gull Wing
• Outline dimensions must be 6.20mm x 6.20mm
• Operating force must be 300gf
• Ingress protection must be IP67
• Operating temperature range must be -40°C ~ 125°C
• Switch travel must be 0.20mm
• Mechanical life must be 300,000 Cycles

The KSC343GLFG meets all these parameters and qualifies as a direct equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The KSC343GLFG is the direct functional equivalent of the obsolete KSC343G. Both components share identical electrical specifications, mechanical dimensions, and performance characteristics across all critical parameters.

The primary distinction between these parts is product status and regulatory compliance. The KSC343G is obsolete and RoHS non-compliant, while the KSC343GLFG is active and ROHS3 compliant. For new designs or ongoing production requiring RoHS compliance, the KSC343GLFG is the appropriate selection. The KSC343GLFG is supplied in Tape & Reel packaging, suitable for automated assembly processes.

Both parts maintain identical moisture sensitivity levels, REACH status, and export classification, ensuring no additional compliance considerations arise from substitution.

Frequently Asked Questions (FAQ)

Q: Can KSC343GLFG be used as a direct replacement for KSC343G?

A: Yes. The KSC343GLFG meets all electrical and mechanical specifications of the KSC343G, including circuit configuration, contact rating, mounting type, actuator dimensions, operating force, ingress protection, temperature range, and mechanical life.

Q: What is the primary difference between KSC343G and KSC343GLFG?

A: The KSC343G is obsolete and RoHS non-compliant, while the KSC343GLFG is active production and ROHS3 compliant. The KSC343GLFG is supplied in Tape & Reel packaging.

Q: Are there packaging considerations when switching to KSC343GLFG?

A: The KSC343GLFG is supplied in Tape & Reel format, which is standard for automated surface mount assembly. If the original KSC343G was supplied in alternative packaging, procurement should confirm the Tape & Reel format is compatible with assembly equipment.

Q: Do compliance certifications differ between these parts?

A: Both parts share identical REACH status, ECCN classification, and HTSUS codes. The KSC343GLFG provides ROHS3 compliance, which the KSC343G does not offer.

Q: Is the moisture sensitivity level the same for both parts?

A: Yes. Both KSC343G and KSC343GLFG have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions.
