KS-00Q-01 Equivalent & Substitute Parts

Part Overview

The KS-00Q-01 is a pushbutton switch manufactured by E-Switch, configured as a Standard SPST-NO (Single Pole Single Throw - Normally Open) through-hole component. This part is rated for 10mA DC at 35V with a square black button actuator and PC pin termination. The product is currently obsolete, necessitating identification of functionally compatible alternatives for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KS-00Q-01 is determined by the following critical parameters:

Circuit configuration must remain SPST-NO to maintain identical electrical function. Mounting type must be through-hole to ensure PCB compatibility without redesign. Termination style must be PC pin for direct footprint compatibility. Actuator type (square button) and color (black) ensure mechanical and aesthetic consistency.

Electrical ratings form the substitution boundary: the substitute part must support the application's maximum voltage (35V) and current (10mA) requirements. Operating temperature range must encompass the application environment. Mechanical and electrical life specifications must meet or exceed the original part's performance expectations.

The 330E11BLK meets all substitution criteria: identical circuit configuration (SPST-NO), mounting type (through-hole), termination style (PC pin), and actuator characteristics (square black button). Its electrical ratings (25mA at 50V) exceed the KS-00Q-01 requirements, providing design margin. Enhanced mechanical life (1,000,000 cycles) and electrical life (1,000,000 cycles) represent improved durability. The substitute part is active in production, ensuring long-term availability.

Parameter Comparison

Engineering Selection Recommendations

The 330E11BLK is the qualified substitute for the obsolete KS-00Q-01. Both parts are manufactured by E-Switch and maintain identical electrical function, mechanical interface, and regulatory compliance (ROHS3).

The substitute part provides superior electrical and mechanical performance: current and voltage ratings exceed application requirements, and mechanical/electrical life specifications are doubled. Both parts operate within the -20°C to 70°C range, which covers the majority of industrial and commercial applications. Applications requiring operation above 70°C must evaluate the narrower temperature range of the 330E11BLK against specific environmental requirements.

Active production status of the 330E11BLK ensures component availability and supply chain continuity, eliminating obsolescence risk associated with the original part.

Frequently Asked Questions (FAQ)

Q: Can the 330E11BLK directly replace the KS-00Q-01 without PCB modification?

A: Yes. Both parts share identical mounting type (through-hole), termination style (PC pin), and actuator configuration (square black button). No PCB redesign is required.

Q: Are the electrical ratings of the 330E11BLK sufficient for applications designed for the KS-00Q-01?

A: Yes. The 330E11BLK is rated for 25mA at 50V, exceeding the KS-00Q-01 specification of 10mA at 35V. The substitute part operates safely within all original application parameters.

Q: What is the impact of the narrower operating temperature range of the 330E11BLK?

A: The 330E11BLK operates from -20°C to 70°C, compared to the KS-00Q-01 range of -20°C to 85°C. Applications operating above 70°C must confirm compatibility with the substitute part's upper temperature limit.

Q: Does the 330E11BLK provide improved reliability compared to the KS-00Q-01?

A: Yes. The 330E11BLK specifies 1,000,000 mechanical cycles and 1,000,000 electrical cycles, compared to 500,000 and 250,000 cycles respectively for the KS-00Q-01. Enhanced life ratings indicate improved durability for extended-use applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the KS-00Q-01 and 330E11BLK are ROHS3 compliant, meeting environmental and regulatory requirements for electronic component manufacturing and use.

Q: What is the packaging difference between these parts?

A: The KS-00Q-01 is supplied in standard packaging, while the 330E11BLK is supplied in bulk packaging. Bulk packaging does not affect component functionality or electrical performance.
