MB2065SS1G01-CC Equivalent & Substitute Parts

Part Overview

The MB2065SS1G01-CC is an obsolete pushbutton switch manufactured by NKK Switches, classified as SPDT (Single Pole Double Throw) with On-On switching function. This component is rated for 0.4VA at 28V AC/DC operation and features a red round button actuator with solder lug termination for panel mount, rear installation. With 1,088 units currently in stock, this part remains available despite its obsolete status. Due to the product's obsolescence, identifying functionally equivalent alternatives is essential for system redesign, long-term supply chain planning, and new production runs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2065SS1G01-CC is determined by the following critical parameters:

Circuit Configuration & Function: The substitute must maintain SPDT topology with On-On switching capability to preserve electrical behavior in the host system.

Termination Style: Solder lug termination is required for direct PCB or panel integration without adapter components.

Mounting Configuration: Panel mount, rear installation ensures mechanical compatibility with existing enclosure cutouts and assembly procedures.

Voltage & Current Ratings: The substitute must support operation at or above the specified 28V AC/DC and 0.4VA ratings. Higher ratings provide operational margin and are acceptable; lower ratings are not.

Environmental Compliance: RoHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity ensure regulatory alignment and storage flexibility.

The identified substitute, TE Connectivity ALCOSWITCH 1977739-1, meets these core substitution criteria while offering enhanced electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution: The 1977739-1 is suitable as a functional equivalent where the host system can accommodate the higher voltage (125V AC) and current (3A AC) ratings. The substitute's active product status ensures long-term availability and supply chain continuity, addressing the primary limitation of the obsolete MB2065SS1G01-CC.

Compliance Alignment: Both parts maintain ROHS3 compliance and MSL Level 1 moisture sensitivity, ensuring regulatory and storage compatibility with existing supply chain processes.

Performance Trade-offs: The substitute provides enhanced electrical performance (higher voltage and current capacity) but operates within a slightly narrower temperature range (-20°C to 80°C versus -30°C to 85°C). The electrical life specification of the substitute (25,000 cycles) is lower than the main part (50,000 cycles); this difference is acceptable for applications where cycle count does not approach these limits.

Mechanical Compatibility: Both parts feature panel mount, rear installation with solder lug termination. Verification of panel cutout dimensions is recommended, as the main part specifies a circular 6.50mm diameter cutout while the substitute does not provide this specification.

Frequently Asked Questions (FAQ)

Q: Can the 1977739-1 directly replace the MB2065SS1G01-CC in all applications?

A: The 1977739-1 is functionally equivalent for SPDT On-On switching applications. However, the host system must tolerate the substitute's higher voltage (125V AC) and current (3A AC) ratings. If the system is designed specifically for 28V operation, the substitute will function correctly but will not operate at its rated capacity. Panel cutout dimensions must be verified for mechanical fit.

Q: What is the primary reason for seeking a substitute?

A: The MB2065SS1G01-CC is classified as obsolete. The 1977739-1 is an active product with confirmed long-term availability, making it suitable for new production runs and systems requiring extended supply chain support.

Q: Are there compliance or environmental concerns with substitution?

A: Both parts are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity ratings. No compliance barriers exist for substitution. Both parts are classified under ECCN EAR99 and HTSUS 8536.50.9033.

Q: How do the electrical life specifications compare?

A: The main part specifies 50,000 electrical cycles; the substitute specifies 25,000 cycles. For applications operating below 25,000 cycles, this difference is not a limiting factor. Applications approaching or exceeding 25,000 cycles require evaluation of actual duty cycle requirements.

Q: What is the difference in operating temperature range?

A: The main part operates from -30°C to 85°C; the substitute operates from -20°C to 80°C. The substitute's range is narrower by 10°C at the lower end and 5°C at the upper end. Applications operating within -20°C to 80°C experience no limitation.

Q: Does the substitute include the same actuator type?

A: No. The main part features a round button actuator with no marking; the substitute features a plunger for cap design. This mechanical difference may affect user interface feel and panel aesthetics but does not impact electrical function or compatibility.
