Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2085LS1W03-CA is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: DPDT
• Switch function: On-On
• Voltage rating: 125V AC minimum / 30V DC minimum
• Current rating: 6A AC minimum / 3A DC minimum
• Mounting type: Panel Mount, Rear
• Panel cutout dimensions: Circular 6.50mm Dia
• Termination style: PC Pin
• Operating temperature range: -30°C ~ 85°C or broader
• RoHS3 compliance

Identified Substitutes:

MBN22LS1W03-CA (NKK Switches): Classified as MFR Recommended substitute. Maintains identical circuit configuration, voltage/current ratings, mounting specifications, and termination style. Active product status ensures ongoing availability.

8N2012-Z (Nidec Components Corporation): Classified as Similar substitute. Meets all mandatory electrical parameters (DPDT, On-On, 125V AC, 30V DC, 6A AC, 4A DC). Maintains identical mounting type, panel cutout dimensions, termination style, and operating temperature range. Active product status with enhanced electrical life rating (40,000 cycles vs. 25,000 cycles).

Parameter Comparison

Engineering Selection Recommendations

MBN22LS1W03-CA: Designated as the MFR Recommended substitute by the original manufacturer. Active product status ensures supply chain continuity and technical support availability. ROHS3 compliance maintained. Selection of this part eliminates obsolescence risk while preserving design compatibility.

8N2012-Z: Active product from alternative manufacturer (Nidec Components Corporation). Meets all mandatory electrical and mechanical parameters. Provides enhanced electrical life specification (40,000 cycles vs. 25,000 cycles), offering extended operational durability. DC current rating increased to 4A, providing additional margin in DC applications. ROHS3 compliance and MSL 1 rating maintained. Suitable for applications requiring extended component lifecycle or higher DC current capacity.

Both substitutes maintain identical panel cutout dimensions (6.50mm Dia), enabling direct mechanical replacement without enclosure modification. PC Pin termination compatibility ensures electrical connection without redesign.

Frequently Asked Questions (FAQ)

Q: Can MBN22LS1W03-CA directly replace MB2085LS1W03-CA?

A: MBN22LS1W03-CA is designated as the MFR Recommended substitute. Both components are manufactured by NKK Switches and maintain identical circuit configuration (DPDT), switch function (On-On), and termination style (PC Pin). Panel cutout dimensions are compatible (6.50mm Dia circular). Direct mechanical and electrical replacement is supported.

Q: What are the key differences between 8N2012-Z and the original MB2085LS1W03-CA?

A: 8N2012-Z is manufactured by Nidec Components Corporation rather than NKK Switches. Electrical specifications are equivalent or superior: AC current rating matches at 6A, DC current rating increases from 3A to 4A, voltage ratings remain identical (125V AC / 30V DC). Electrical life is enhanced to 40,000 cycles versus 25,000 cycles. Panel cutout dimensions and mounting type are identical. Both components are ROHS3 compliant with MSL 1 rating.

Q: Are there any mechanical compatibility concerns with these substitutes?

A: Both substitute parts maintain the identical panel cutout dimension specification (Circular 6.50mm Dia) and Panel Mount, Rear mounting type. No enclosure modification is required. PC Pin termination is consistent across all three components, eliminating connector redesign requirements.

Q: Which substitute should be selected for new designs?

A: For new designs, either active substitute is acceptable. MBN22LS1W03-CA maintains manufacturer continuity with NKK Switches. 8N2012-Z offers enhanced electrical life (40,000 cycles) and increased DC current capacity (4A), providing additional design margin. Selection depends on supply chain preference and performance requirements specific to the application.

Q: Are compliance certifications maintained across all substitutes?

A: All three components maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating. ECCN and HTSUS classifications are identical (EAR99 and 8536.50.9035 respectively), ensuring regulatory consistency for procurement and export documentation.
