NKK Switches S114/C Toggle Switch DPST 5A 125V Equivalent & Substitute Parts

Part Overview

The NKK Switches S114/C is a panel-mounted toggle switch with DPST (Double Pole Single Throw) circuit configuration, rated for 5A at 125V AC and 30V DC. This component features a standard round actuator with solder lug termination and operates across a temperature range of -10°C to 70°C. The S114/C is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design requirements and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

The NKK Switches S331/C qualifies as a substitute for the S114/C based on the following alignment of critical parameters:

Matching Parameters:

• Circuit configuration: DPST
• Switch function: On-Off
• Voltage rating - AC: 125V
• Voltage rating - DC: 30V
• Mounting type: Panel Mount
• Actuator type: Standard Round
• Termination style: Solder Lug
• Panel cutout dimensions: Circular - 12.50mm Dia
• Bushing thread: M12 x 1
• Operating temperature range: -10°C ~ 70°C
• Actuator material: Brass, Chrome Plated
• RoHS compliance: ROHS3 Compliant

Differing Parameters:

• Current rating: S331/C rated for 25A versus S114/C rated for 5A
• Actuator length: S331/C 17.50mm versus S114/C 18.00mm
• Electrical life: S331/C 15,000 cycles versus S114/C 10,000 cycles
• Product status: S331/C is Last Time Buy versus S114/C is Obsolete

The S331/C provides enhanced electrical performance with higher current capacity and extended cycle life while maintaining mechanical and electrical compatibility through identical mounting interfaces and voltage specifications.

Parameter Comparison

Engineering Selection Recommendations

The S331/C is suitable as a substitute for the S114/C in applications where the circuit topology, voltage specifications, and mounting interface are primary design constraints. Both components maintain ROHS3 compliance and identical mechanical mounting characteristics through the M12 x 1 bushing thread and 12.50mm circular panel cutout.

The S331/C offers increased current capacity (25A versus 5A) and extended electrical life (15,000 versus 10,000 cycles), providing design margin for applications operating at or near the S114/C current rating. The 0.50mm reduction in actuator length (17.50mm versus 18.00mm) must be evaluated against panel geometry and operator interface requirements.

The S331/C status as Last Time Buy indicates limited future availability, requiring procurement planning aligned with component lifecycle management strategies.

Frequently Asked Questions (FAQ)

Q: Can the S331/C directly replace the S114/C in existing designs?

A: The S331/C maintains identical circuit configuration (DPST), voltage ratings (125V AC / 30V DC), mounting interface (M12 x 1 bushing, 12.50mm panel cutout), and termination style (solder lug). Substitution is mechanically and electrically compatible. The 0.50mm actuator length difference and increased current rating (25A versus 5A) must be verified against specific panel geometry and circuit requirements.

Q: What are the key differences between these parts?

A: The primary differences are current rating (S331/C 25A versus S114/C 5A), actuator length (S331/C 17.50mm versus S114/C 18.00mm), electrical life (S331/C 15,000 cycles versus S114/C 10,000 cycles), and product status (S331/C Last Time Buy versus S114/C Obsolete).

Q: Are both parts RoHS compliant?

A: Yes, both the S114/C and S331/C are ROHS3 compliant.

Q: What is the significance of the product status difference?

A: The S114/C is classified as obsolete, indicating discontinued production and limited availability. The S331/C is Last Time Buy status, indicating a final production run with defined availability window. Both statuses require procurement planning for long-term supply chain management.

Q: Does the actuator length difference affect panel mounting?

A: The 0.50mm difference in actuator length (S331/C 17.50mm versus S114/C 18.00mm) must be evaluated against panel thickness, operator interface clearance, and aesthetic requirements. The identical panel cutout dimensions and bushing thread ensure mechanical mounting compatibility.
