NKK Switches M2015LL2G40 Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The M2015LL2G40 is an obsolete toggle switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with 0.4VA current rating at 28V. This through-hole, right-angle vertical mount switch with locking lever actuator and PC pin termination is no longer in active production. Finding equivalent or substitute components is necessary for system maintenance, repair, and redesign applications where the original part is unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M2015LL2G40 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: SPDT
• Current rating: 0.4VA (AC/DC)
• Mounting type: Through Hole, Right Angle, Vertical
• Actuator type: Locking Lever
• Termination style: PC Pin
• Switch function: On-Mom

Allowable Variation Parameters:

• Voltage rating: The substitute must meet or exceed the 28V requirement
• Actuator length: Physical differences acceptable if mechanical fit permits
• Operating temperature range: Substitute range may differ if application requirements are met
• Product status: Active or obsolete status does not restrict substitution

The D22015LV meets all mandatory matching parameters and exceeds the voltage requirement at 48V, making it a valid substitute for applications operating at or below 28V.

Parameter Comparison

Engineering Selection Recommendations

The D22015LV is a valid substitute for the M2015LL2G40 based on the following engineering criteria:

Electrical Compatibility: Both parts share identical circuit configuration (SPDT), current rating (0.4VA AC/DC), and switch function (On-Mom). The D22015LV's higher voltage rating (48V) is compatible with applications designed for 28V operation, as the substitute can safely handle lower voltage levels.

Mechanical Compatibility: Both parts feature identical mounting type (through-hole, right-angle, vertical), actuator type (locking lever), and termination style (PC pin). The D22015LV actuator is 2.90mm longer (19.40mm vs. 16.50mm), requiring verification of mechanical clearance in the target application.

Compliance and Production Status: The D22015LV is ROHS3 compliant and currently in active production, ensuring long-term availability and supply chain reliability compared to the obsolete M2015LL2G40.

Application Constraints: The D22015LV operating temperature range (-10°C to 70°C) is narrower than the M2015LL2G40 (-30°C to 85°C). Applications requiring operation below -10°C or above 70°C must be evaluated against the substitute's specifications.

Frequently Asked Questions (FAQ)

Q: Can the D22015LV directly replace the M2015LL2G40 in all applications?

A: The D22015LV is electrically and functionally compatible with the M2015LL2G40 for applications operating within the substitute's temperature range (-10°C to 70°C) and with adequate mechanical clearance for the longer 19.40mm actuator. Applications requiring the full -30°C to 85°C temperature range of the original part require alternative solutions.

Q: What is the significance of the voltage rating difference between the two parts?

A: The M2015LL2G40 is rated for 28V (AC/DC), while the D22015LV is rated for 48V (AC/DC). A higher voltage rating indicates the component can safely operate at lower voltages. The D22015LV can be used in any application designed for 28V without electrical degradation.

Q: How does the 2.90mm difference in actuator length affect substitution?

A: The D22015LV actuator is 2.90mm longer than the M2015LL2G40. Physical fit must be verified in the target application, including panel cutout dimensions, surrounding component clearance, and operator access requirements. If mechanical constraints prevent installation, alternative parts must be evaluated.

Q: Are both parts RoHS compliant?

A: Yes, both the M2015LL2G40 and D22015LV are ROHS3 compliant, meeting environmental and regulatory requirements for electronic component manufacturing and use.

Q: What is the difference in product status between these parts?

A: The M2015LL2G40 is obsolete and no longer manufactured, while the D22015LV is active and currently in production. The active status of the D22015LV ensures continued availability and supply chain support for future procurement needs.

Q: Do both parts have the same electrical life rating?

A: Yes, both parts are rated for 50,000 electrical cycles, indicating identical mechanical durability and switch reliability under normal operating conditions.
