NKK Switches S116R Toggle Switch DPDT 5A 125V Equivalent & Substitute Parts

Part Overview

The NKK Switches S116R is a panel-mount toggle switch with DPDT (Double Pole Double Throw) configuration rated for 5A at 125V AC and 30V DC. This switch features a paddle actuator and non-illuminated design with solder lug termination. The product is classified as obsolete, making identification of equivalent substitute parts essential for ongoing maintenance, repair, and system upgrades where this component is specified.

Key Parameters

Substitute Part Grouping Explanation

The NKK Switches S332R qualifies as a substitute for the S116R based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters:

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

Differing Parameters:

• Current rating: S332R is rated for 20A (AC/DC), exceeding the S116R's 5A rating
• Actuator type: S332R uses flatted actuator versus S116R's paddle actuator
• Actuator length: S332R measures 27.00mm versus S116R's 29.00mm
• Electrical life: S332R rated for 15,000 cycles versus S116R's 10,000 cycles
• Actuator material: S332R uses PBT versus S116R's polyamide (PA)
• Product status: S332R is active versus S116R's obsolete status

Parameter Comparison

Engineering Selection Recommendations

The S332R is suitable as a substitute for the S116R in applications where the following conditions are met:

The S332R maintains identical electrical specifications for voltage ratings (125V AC / 30V DC) and circuit topology (DPDT On-On configuration). Both parts share identical mechanical mounting characteristics, including panel cutout dimensions (12.50mm circular), bushing thread (M12 x 1), and solder lug termination. Both components operate within the same temperature range (-10°C ~ 70°C) and maintain ROHS3 compliance.

The S332R's higher current rating (20A versus 5A) and extended electrical life (15,000 versus 10,000 cycles) represent performance enhancements suitable for applications requiring greater current capacity or extended operational cycles. The S332R's active product status ensures ongoing availability and supply chain continuity, addressing the obsolescence of the original S116R.

Physical differences in actuator design (flatted versus paddle) and actuator length (27.00mm versus 29.00mm) require verification of mechanical fit within the specific panel or enclosure design. The change in actuator material from polyamide to PBT does not affect electrical performance but may influence tactile feedback and long-term durability characteristics.

Frequently Asked Questions (FAQ)

Q: Can the S332R directly replace the S116R in all applications?

A: The S332R maintains identical electrical ratings and mechanical mounting specifications. However, the difference in actuator type (flatted versus paddle) and length (27.00mm versus 29.00mm) requires physical verification within the specific installation environment to confirm clearance and operational fit.

Q: What is the significance of the higher current rating on the S332R?

A: The S332R is rated for 20A compared to the S116R's 5A rating. This higher rating provides additional capacity margin in applications operating at or near the original 5A specification. Applications operating below 5A are fully compatible with the S332R.

Q: Are both parts compliant with current regulatory standards?

A: Both the S116R and S332R are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: Why is the S116R classified as obsolete?

A: The S116R is listed as obsolete by the manufacturer. The S332R, classified as active, represents the current production equivalent within the NKK Switches S-series toggle switch portfolio.

Q: What is the difference in electrical life between these parts?

A: The S116R is rated for 10,000 electrical cycles, while the S332R is rated for 15,000 cycles. This extended cycle rating on the S332R indicates enhanced durability for applications with frequent switching operations.

Q: Are the termination styles identical?

A: Both parts use solder lug termination, ensuring compatibility with existing PCB layouts and wiring harness connections designed for the S116R.
