Key Parameters

Substitute Part Grouping Explanation

Substitution of the SB265 is determined by the following critical parameters:

Mechanical Compatibility:

• Panel Mount, Rear configuration with circular 12.50mm panel cutout ensures physical fit within existing enclosures
• Solder lug termination maintains electrical connection compatibility with legacy PCB layouts

Electrical Compatibility:

• Minimum current rating of 6A at 125V AC is required to handle the original circuit load
• SPST or SPDT circuit configurations are acceptable, as SPDT provides additional switching capability while maintaining SPST functionality through single contact pair operation

Regulatory Compliance:

• ROHS3 compliance and REACH Unaffected status ensure environmental and regulatory alignment

The substitute part MB2065SB1W01 meets these criteria through identical mechanical mounting, equivalent or superior electrical ratings, and matching regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The MB2065SB1W01 serves as a direct substitute for the SB265 based on the following engineering criteria:

Electrical Equivalence: Both components maintain 6A at 125V AC rating, ensuring load compatibility. The MB2065SB1W01 SPDT configuration provides additional switching flexibility while remaining backward compatible with SPST circuit applications.

Mechanical Fit: Identical panel mount configuration and 12.50mm circular cutout dimensions ensure installation without enclosure modification.

Regulatory Compliance: Both components maintain ROHS3 compliance and REACH Unaffected status, satisfying environmental and regulatory requirements.

Enhanced Performance: The MB2065SB1W01 offers extended operating temperature range (-30°C to 85°C versus -10°C to 70°C), increased mechanical life (100,000 cycles versus 30,000 cycles), and improved electrical life (25,000 cycles versus 10,000 cycles), providing superior reliability in replacement applications.

Product Status: Both components are classified as Obsolete. Current inventory availability should be verified through authorized distributors prior to procurement.

Frequently Asked Questions (FAQ)

Q: Can MB2065SB1W01 replace SB265 in existing applications?

A: Yes. The MB2065SB1W01 maintains identical mechanical mounting (Panel Mount, Rear with 12.50mm circular cutout), equivalent AC electrical ratings (6A at 125V), and matching termination style (Solder Lug). The SPDT configuration is compatible with SPST circuit applications.

Q: What are the key differences between SB265 and MB2065SB1W01?

A: The primary difference is circuit configuration: SB265 is SPST (Single Pole Single Throw), while MB2065SB1W01 is SPDT (Single Pole Double Throw). MB2065SB1W01 provides extended operating temperature range, higher mechanical life (100,000 cycles versus 30,000 cycles), and greater electrical life (25,000 cycles versus 10,000 cycles).

Q: Are both components RoHS compliant?

A: Yes. Both SB265 and MB2065SB1W01 are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards.

Q: What is the panel cutout requirement for installation?

A: Both components require a circular panel cutout of 12.50mm diameter for Panel Mount, Rear installation.

Q: What termination method is used for both components?

A: Both components use Solder Lug termination, compatible with standard PCB soldering processes and legacy wiring harnesses.

Q: Are there inventory considerations for these Obsolete components?

A: Both SB265 and MB2065SB1W01 are classified as Obsolete. Availability is limited to existing distributor stock. Current inventory status should be confirmed with authorized suppliers before finalizing procurement decisions.
