Engineering Selection Recommendations
MB2411A2G40 (NKK Switches MB2400 Series)
This substitute maintains full electrical and mechanical compatibility with the original MB2011SS2G40-CA. Both components are manufactured by NKK Switches and share identical voltage ratings (28V AC/DC), current capacity (0.4VA), and operating temperature range (-30°C to 85°C). The MB2411A2G40 demonstrates superior performance characteristics with doubled mechanical life (200,000 cycles versus 100,000 cycles) and doubled electrical life (100,000 cycles versus 50,000 cycles). Both parts carry ROHS3 compliance and identical HTSUS classification. The primary distinction is the actuator configuration: MB2411A2G40 uses a plunger-type actuator versus the round button of the original. Both are classified as obsolete products.
8168SH9AV2BE2 (C&K 8060 Series)
This substitute provides electrical and mechanical compatibility with functional equivalence, though with operational constraints. The C&K component maintains SPDT circuit configuration, 0.4VA current rating, On-Mom switch function, through-hole right-angle vertical mounting, and PC pin termination. Critical limitation: voltage rating is 20V (AC/DC) versus the original 28V specification. Operating temperature range is restricted to -30°C to 65°C, narrower than the original -30°C to 85°C range. Electrical life matches the original at 50,000 cycles. Mechanical life is not specified. The 8168SH9AV2BE2 is classified as an active product with ROHS3 compliance. REACH status differs: this component is REACH Affected, whereas the original is REACH Unaffected. The round black button actuator matches the original configuration.
Selection Criteria:
For applications requiring full parameter equivalence and identical voltage/temperature specifications, MB2411A2G40 is the primary substitute. For applications operating at or below 20V with maximum operating temperatures not exceeding 65°C, 8168SH9AV2BE2 is acceptable, with the advantage of active product status and current availability.
Frequently Asked Questions (FAQ)
Q: Can MB2411A2G40 be used as a direct replacement for MB2011SS2G40-CA?
A: Yes. Both components share identical electrical specifications (SPDT, 0.4VA, 28V AC/DC), identical operating temperature range (-30°C to 85°C), identical mounting configuration (through-hole right-angle vertical), and identical termination style (PC pin). The MB2411A2G40 offers enhanced mechanical and electrical life ratings. The actuator type differs (plunger versus round button), which may affect panel aesthetics but does not impact electrical function.
Q: What is the voltage limitation of the 8168SH9AV2BE2 substitute?
A: The 8168SH9AV2BE2 is rated for 20V (AC/DC) maximum, compared to the original 28V specification. This component is suitable only for applications operating at 20V or below. Use in 28V circuits will exceed the component's voltage rating and is not permitted.
Q: Does the operating temperature range difference affect substitution suitability?
A: The 8168SH9AV2BE2 operates within -30°C to 65°C, versus the original -30°C to 85°C range. Applications requiring operation above 65°C must use MB2411A2G40 or the original component. For applications with maximum operating temperatures at or below 65°C, the C&K component is acceptable.
Q: What is the significance of product status (Obsolete versus Active)?
A: The MB2011SS2G40-CA and MB2411A2G40 are both classified as obsolete, indicating discontinued manufacturing. The 8168SH9AV2BE2 is classified as active, indicating current production and ongoing availability. For long-term supply chain planning, the active status of the C&K component may provide procurement advantages, provided voltage and temperature specifications align with application requirements.
Q: Are there packaging differences between these substitutes?
A: Yes. MB2011SS2G40-CA is packaged in standard format (packaging not specified). MB2411A2G40 is supplied in bulk packaging. 8168SH9AV2BE2 is supplied in tray packaging. Packaging format does not affect electrical or mechanical function but may influence procurement quantities and handling procedures.
Q: How do the mechanical and electrical life ratings compare?
A: MB2011SS2G40-CA: 100,000 mechanical cycles, 50,000 electrical cycles. MB2411A2G40: 200,000 mechanical cycles, 100,000 electrical cycles (superior performance). 8168SH9AV2BE2: Mechanical life not specified, 50,000 electrical cycles (matches original electrical life). For applications with high cycle count requirements, MB2411A2G40 provides extended service life.
Q: Are all three components RoHS compliant?
A: Yes. MB2011SS2G40-CA, MB2411A2G40, and 8168SH9AV2BE2 are all ROHS3 compliant. REACH status differs: the original and MB2411A2G40 are REACH Unaffected, while 8168SH9AV2BE2 is REACH Affected. Regulatory requirements for your application region should be verified.
