Key Parameters

Substitute Part Grouping Explanation

The substitute part 3-1825010-8 (TE Connectivity ALCOSWITCH Switches) is identified as an equivalent option based on the following substitution criteria:

Common Electrical Parameters:

• Mounting Type: Through Hole
• Termination Style: PC Pin
• RoHS3 Compliance: Both parts meet ROHS3 requirements
• REACH Status: Both parts are REACH Unaffected
• ECCN Classification: Both classified as EAR99

Substitution Limitations: The 3-1825010-8 operates under significantly different electrical constraints. This part features 6PDT circuit configuration with 0.4VA rating at 20V AC/DC, which represents a lower voltage and current capacity compared to the S202091MS02Q. Substitution is valid only when application requirements align with the reduced electrical specifications of the alternative component.

Parameter Comparison

Engineering Selection Recommendations

Both the S202091MS02Q and 3-1825010-8 maintain Active product status and full ROHS3 compliance, ensuring regulatory alignment for current applications. Selection between these components must be determined by application voltage and current requirements. The S202091MS02Q supports higher voltage (125V) and current (6A AC) specifications, making it suitable for standard industrial switching applications. The 3-1825010-8 is restricted to 20V operation with 0.4VA capacity, limiting its use to low-voltage control circuits. Substitution is only valid when the application operates within the electrical constraints of the alternative component.

Frequently Asked Questions (FAQ)

Q: Can the 3-1825010-8 replace the S202091MS02Q in all applications?

A: No. The 3-1825010-8 operates at maximum 20V with 0.4VA capacity, while the S202091MS02Q is rated for 125V at 6A AC. Substitution is valid only for applications operating within the lower voltage and current specifications of the 3-1825010-8.

Q: What are the key differences in circuit configuration?

A: The S202091MS02Q uses DPDT (Double Pole Double Throw) configuration, while the 3-1825010-8 uses 6PDT (Six Pole Double Throw). The 6PDT provides additional switching poles but operates at reduced electrical ratings.

Q: Are both parts through-hole mounted?

A: Yes. Both components use through-hole mounting with PC pin termination, ensuring mechanical compatibility in PCB applications.

Q: Do both parts meet current compliance standards?

A: Yes. Both the S202091MS02Q and 3-1825010-8 are ROHS3 compliant and REACH Unaffected, meeting current regulatory requirements.

Q: What is the operating temperature difference?

A: The S202091MS02Q operates from -30°C to 65°C, while the 3-1825010-8 operates from -40°C to 80°C. The 3-1825010-8 provides extended low-temperature capability and higher maximum temperature rating.

Q: How do electrical life ratings compare?

A: The S202091MS02Q is rated for 10,000 electrical cycles, while the 3-1825010-8 is rated for 15,000 electrical cycles. The 3-1825010-8 provides extended cycle life under its specified electrical parameters.
