Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2085SS2G30-CA is determined by the following critical parameters:

Circuit Configuration: Both the main part and substitute must maintain DPDT topology to preserve electrical functionality within the host system.

Switch Function: On-On operation must be preserved to ensure identical switching behavior.

Mounting Type: Through-hole, right-angle configuration is mandatory for mechanical compatibility with existing PCB layouts.

Termination Style: PC pin termination is required for direct connection compatibility.

Voltage Rating - DC: The substitute must support a minimum of 28V DC to meet the electrical requirements of the application.

Current Rating: The substitute must support a minimum of 0.4VA to handle the specified load.

Actuator Type: Round button actuators ensure consistent user interface and mechanical fit.

Environmental Compliance: RoHS3 compliance is required for regulatory alignment.

The identified substitute part 8261LH9A3QE2 satisfies all mandatory substitution criteria within the allowed parameter set.

Parameter Comparison

Engineering Selection Recommendations

The 8261LH9A3QE2 is functionally equivalent to the MB2085SS2G30-CA for applications operating within the specified parameter constraints. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity compared to the obsolete main part.

Both components maintain identical DPDT circuit topology, On-On switching function, PC pin termination, and RoHS3 compliance. The substitute part exceeds the current rating requirement (6A versus 0.4VA) and maintains DC voltage compatibility at 28V.

The operating temperature range of the substitute part (-30°C to 65°C) is narrower than the main part (-30°C to 85°C). Applications requiring operation above 65°C must evaluate thermal performance requirements independently.

Frequently Asked Questions (FAQ)

Q: Can the 8261LH9A3QE2 directly replace the MB2085SS2G30-CA in existing designs?

A: Yes, provided the application operates within the temperature range of -30°C to 65°C. Both components share identical circuit topology (DPDT), switch function (On-On), mounting configuration (through-hole, right-angle), and termination style (PC pin). The substitute part's higher current rating (6A) and AC voltage rating (120V) do not create compatibility issues in applications designed for 0.4VA at 28V.

Q: What are the key differences between these two parts?

A: The primary differences are product status (obsolete versus active), manufacturer (NKK Switches versus C&K), operating temperature upper limit (85°C versus 65°C), and current/voltage ratings. The substitute part provides higher electrical capacity and active production status.

Q: Are there any compliance or certification concerns with substitution?

A: Both parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity ratings. The substitute part is REACH Affected, whereas the main part is REACH Unaffected. Applications subject to REACH regulations must evaluate this distinction independently.

Q: Does packaging differ between these components?

A: The main part packaging is listed as standard through-hole format. The substitute part is supplied in tray packaging. PCB assembly processes must accommodate the tray packaging format accordingly.
