M2113LCFG03 Equivalent & Substitute Parts

Part Overview

The M2113LCFG03 is an illuminated toggle switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuitry with On-Off-On switching function. This panel-mount component is rated for 0.4VA at 28V AC/DC with LED illumination in green/red. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations where this switch type is required.

Key Parameters

Substitute Part Grouping Explanation

The A121K12KCG-M8 from Electroswitch qualifies as a functional substitute based on the following critical parameters:

Matching Parameters (Substitution Basis):

• Circuit configuration: SPDT
• Switch function: On-Off-On
• Mounting type: Panel Mount
• Termination style: PC Pin
• Bushing thread: 1/4-40
• DC voltage rating: 28V (meets minimum requirement)
• Epoxy sealed terminals (environmental protection equivalent)

Parameter Differences (Design Considerations):

• Current rating: A121K12KCG-M8 rated 6A versus M2113LCFG03 rated 0.4VA (higher capacity in substitute)
• AC voltage rating: A121K12KCG-M8 rated 125V versus M2113LCFG03 rated 28V (higher capacity in substitute)
• Illumination: M2113LCFG03 includes LED illumination; A121K12KCG-M8 is non-illuminated
• Actuator type: M2113LCFG03 uses standard round; A121K12KCG-M8 uses locking lever
• Operating temperature: A121K12KCG-M8 range -30°C to 90°C versus M2113LCFG03 range -10°C to 55°C (wider range in substitute)
• Electrical life: A121K12KCG-M8 rated 60,000 cycles versus M2113LCFG03 rated 25,000 cycles (higher endurance in substitute)

Parameter Comparison

Engineering Selection Recommendations

The A121K12KCG-M8 is available as an active product from Electroswitch, addressing the obsolescence status of the M2113LCFG03. Both components maintain RoHS compliance and feature epoxy sealed terminals for environmental protection.

The substitute part exceeds the electrical specifications of the original component across current rating, AC voltage rating, and electrical life cycle count. The wider operating temperature range of the A121K12KCG-M8 provides additional thermal margin for applications operating outside the original -10°C to 55°C specification.

Design integration requires consideration of the following differences: the A121K12KCG-M8 lacks integrated LED illumination present in the M2113LCFG03, and features a locking lever actuator instead of a standard round actuator. Panel cutout dimensions for the A121K12KCG-M8 are not specified in available documentation; confirmation of mechanical compatibility with existing panel openings is necessary before implementation.

Frequently Asked Questions (FAQ)

Q: Can the A121K12KCG-M8 directly replace the M2113LCFG03 in existing applications?

A: Electrical substitution is valid based on matching SPDT circuit configuration, On-Off-On function, 28V DC rating, PC pin termination, and 1/4-40 bushing thread. Mechanical compatibility requires verification of panel cutout dimensions and actuator clearance, as the substitute uses a locking lever actuator versus the original standard round type. The absence of integrated LED illumination in the substitute must be addressed separately if indicator functionality is required.

Q: What are the key parameters that determine substitution eligibility?

A: Critical parameters for toggle switch SPDT substitution include circuit configuration (SPDT), switch function (On-Off-On), mounting type (Panel Mount), termination style (PC Pin), bushing thread specification (1/4-40), and minimum voltage rating compatibility (28V DC). The substitute must meet or exceed the original component's electrical ratings in the application's operating conditions.

Q: Does the higher current rating of the A121K12KCG-M8 affect compatibility?

A: No. The 6A rating of the substitute exceeds the 0.4VA requirement of the original application, providing additional design margin. The component will function correctly in circuits designed for the lower current specification of the M2113LCFG03.

Q: Are there compliance differences between the two components?

A: Both components are RoHS compliant. The M2113LCFG03 carries ROHS3 certification, while the A121K12KCG-M8 is RoHS compliant. Both components are classified under ECCN EAR99 and share the same HTSUS code (8536.50.9065).

Q: What should be considered regarding the illumination difference?

A: The M2113LCFG03 includes integrated LED illumination (green/red, 1.7-2VDC), while the A121K12KCG-M8 is non-illuminated. If panel indication is required, external LED assemblies or alternative illuminated switch models must be evaluated separately.
