Engineering Selection Recommendations
Both MPA106F and MPE106F are suitable substitutes for the obsolete MB2011LD3W01-BC based on the following factors:
Product Status: Both substitute parts carry active product status from TE Connectivity ALCOSWITCH Switches, ensuring long-term availability and supply chain stability compared to the obsolete NKK Switches original.
Compliance & Certifications: All three parts maintain ROHS3 compliance. The MPE106F carries REACH Affected status, while MPA106F shows Vendor Undefined REACH status. The original MB2011LD3W01-BC is REACH Unaffected. Design teams must confirm REACH compliance requirements for their specific application.
Electrical Performance: Both substitutes exceed the original part's electrical life specification (50,000 cycles versus 25,000 cycles), providing enhanced durability. DC current ratings of 4A exceed the original 3A specification. DC voltage ratings of 28V are marginally lower than the original 30V and require application-level verification if DC operation approaches 30V.
Mechanical Compatibility: Panel cutout diameter differs by 0.15mm (6.35mm versus 6.50mm). This reduction requires mechanical panel layout review to confirm adequate clearance and mounting stability.
Environmental Performance: Operating temperature range narrows from -30°C to 85°C to -20°C to 80°C. Applications requiring operation below -20°C or above 80°C must be evaluated against actual system requirements. MPE106F provides Splash Proof ingress protection; MPA106F ingress protection is not specified.
Frequently Asked Questions (FAQ)
Q: Can MPA106F and MPE106F be used interchangeably as substitutes for MB2011LD3W01-BC?
A: Both parts meet the core electrical and mechanical requirements for substitution. Selection between them depends on ingress protection requirements. MPE106F provides Splash Proof protection; MPA106F does not specify ingress protection. For applications requiring environmental sealing, MPE106F is the preferred choice.
Q: What is the impact of the 0.15mm panel cutout diameter difference?
A: The substitute parts require a 6.35mm diameter cutout versus the original 6.50mm specification. Panel designs must accommodate this smaller diameter. Existing panels designed for 6.50mm cutouts may require modification or use of adapter hardware.
Q: Are there temperature range limitations with the substitute parts?
A: Yes. Both MPA106F and MPE106F operate from -20°C to 80°C, compared to the original -30°C to 85°C range. Applications requiring operation below -20°C or above 80°C cannot use these substitutes without additional thermal management or alternative component selection.
Q: Do the substitute parts maintain the same DC voltage rating?
A: No. Substitute parts are rated 28V DC versus the original 30V DC. Applications operating at or near 30V DC require circuit-level analysis to confirm adequate safety margin with the reduced rating.
Q: What is the advantage of the higher electrical life rating in the substitute parts?
A: Both MPA106F and MPE106F are rated for 50,000 electrical cycles compared to 25,000 cycles for the original part. This doubling of electrical life extends component service life and reduces replacement frequency in high-cycle applications.
Q: Are compliance certifications identical across all three parts?
A: All three parts are ROHS3 compliant. REACH status differs: MB2011LD3W01-BC is REACH Unaffected, MPA106F shows Vendor Undefined, and MPE106F is REACH Affected. Design teams must verify REACH compliance requirements for their target markets.
