Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2085SS1G01 is determined by strict equivalence across the following critical parameters:

• Circuit configuration (DPDT)
• Switch function (On-On)
• Current and voltage ratings (0.4VA at 28V AC/DC)
• Mounting type (Panel Mount, Rear)
• Termination style (Solder Lug)
• Mechanical and electrical life specifications
• RoHS compliance status

The EB2085G qualifies as a direct substitute based on matching all primary electrical and mechanical specifications. Both components share identical circuit topology, current/voltage ratings, mounting configuration, and termination method. Compliance certifications (ROHS3, REACH Unaffected, EAR99) are equivalent across both parts.

Parameter Comparison

Engineering Selection Recommendations

The EB2085G is qualified as a direct electrical and mechanical substitute for the MB2085SS1G01. Both components maintain identical DPDT circuit topology, current/voltage specifications, and mechanical life ratings. The EB2085G carries active product status from NKK Switches, ensuring ongoing availability and supply chain continuity compared to the obsolete MB2085SS1G01.

Both parts satisfy ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for equivalent component selection. The EB2085G is available in bulk packaging with 990 units in stock, supporting production requirements.

Physical integration considerations include panel cutout diameter variance (6.50mm for MB2085SS1G01 versus 6.35mm for EB2085G) and operating temperature range differences (-30°C to 85°C versus -10°C to 70°C). These dimensional and thermal specifications must be evaluated against specific application requirements prior to implementation.

Frequently Asked Questions (FAQ)

Q: What makes EB2085G a valid substitute for MB2085SS1G01?

A: The EB2085G matches all critical electrical parameters: DPDT circuit, On-On function, 0.4VA current rating, 28V AC/DC voltage rating, panel mount rear configuration, and solder lug termination. Mechanical life (100,000 cycles) and electrical life (50,000 cycles) specifications are identical. Both components are ROHS3 compliant.

Q: Are there dimensional differences between these parts?

A: Yes. The panel cutout diameter differs: MB2085SS1G01 requires 6.50mm circular cutout, while EB2085G requires 6.35mm circular cutout. Panel modifications may be necessary depending on existing mounting hole specifications.

Q: What is the operating temperature difference?

A: MB2085SS1G01 operates from -30°C to 85°C, while EB2085G operates from -10°C to 70°C. Applications requiring operation below -10°C or above 70°C must retain the original MB2085SS1G01 or identify alternative solutions.

Q: Why is the original part listed as obsolete?

A: MB2085SS1G01 is classified as obsolete by the manufacturer. The EB2085G represents the active product line equivalent, ensuring long-term component availability and supply chain reliability.

Q: What packaging options are available?

A: MB2085SS1G01 is supplied in standard packaging, while EB2085G is available in bulk packaging. Inventory availability is 869 units for the original part and 990 units for the substitute.
