Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 48ASSP3S1M2RAT is determined by the following critical parameters:

Circuit Configuration: SPDT topology is mandatory for functional equivalence.

Mounting Type: Panel mount configuration must be maintained.

Termination Style: PC pin termination is required for PCB compatibility.

Actuator Specifications: Actuator length of 5.08mm and switch travel of 2.16mm establish mechanical compatibility with panel cutouts and mechanical interfaces.

Electrical Parameters: Current and voltage ratings must meet or exceed the application requirements. The 48ASSP3S1M2RAT operates at 0.4VA/20V; substitute parts with higher ratings remain compatible for lower-demand applications.

Environmental Compliance: RoHS3 compliance and REACH unaffected status are mandatory for regulatory alignment.

The substitute part 1103M1S3CQE2 from C&K meets these criteria with matching circuit configuration, mounting type, termination style, and actuator dimensions, while providing enhanced electrical ratings (6A/120V AC, 28V DC) and extended electrical life (40,000 cycles).

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (48ASSP3S1M2RAT): Select this part when the application requires the specific thermal performance range of -30°C to 85°C and when the 0.4VA/20V rating matches exact circuit requirements. This component is Active status with full ROHS3 compliance and REACH unaffected designation.

Substitute Selection (1103M1S3CQE2): Select this C&K equivalent when higher electrical ratings are acceptable or beneficial for the application. The 6A/120V AC and 28V DC capability provides design margin for applications operating below these thresholds. Extended electrical life of 40,000 cycles offers improved longevity. Both parts maintain identical mechanical interfaces (5.08mm actuator length, 2.16mm travel, panel mount, PC pin termination). Note that the operating temperature range is reduced to -30°C to 65°C; verify this limitation against application requirements.

Both parts are Active status products with ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current and future applications.

Frequently Asked Questions (FAQ)

Q: Can the 1103M1S3CQE2 directly replace the 48ASSP3S1M2RAT in existing designs?

A: Direct mechanical and electrical substitution is possible when the application operates within the 1103M1S3CQE2 specifications. The identical actuator length (5.08mm), switch travel (2.16mm), panel mount configuration, and PC pin termination ensure mechanical compatibility. Verify that the operating temperature range of -30°C to 65°C satisfies application requirements, as this is narrower than the 48ASSP3S1M2RAT range.

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

A: The primary differences are electrical ratings and operating temperature range. The 1103M1S3CQE2 provides higher current capacity (6A versus 0.4VA) and higher AC voltage rating (120V versus 20V), with extended electrical life (40,000 versus 30,000 cycles). The 48ASSP3S1M2RAT supports higher maximum operating temperature (85°C versus 65°C). Contact finish differs: gold on the 48ASSP3S1M2RAT versus silver on the 1103M1S3CQE2.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both the 48ASSP3S1M2RAT and 1103M1S3CQE2 are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic components.

Q: What is the significance of the different contact finishes?

A: The 48ASSP3S1M2RAT uses gold-plated contacts, while the 1103M1S3CQE2 uses silver-plated contacts. Both finishes provide reliable electrical contact and corrosion resistance. Gold plating typically offers superior performance in low-current, low-voltage applications and provides better long-term reliability in humid environments. Silver plating is suitable for general-purpose switching applications and is cost-effective for higher-current applications.

Q: Can I use the 1103M1S3CQE2 in applications requiring the full -30°C to 85°C temperature range?

A: No. The 1103M1S3CQE2 is rated only to 65°C maximum operating temperature. If the application requires operation above 65°C, the 48ASSP3S1M2RAT must be used.

Q: What is the inventory status for these parts?

A: The 48ASSP3S1M2RAT has 879 pieces in stock. The 1103M1S3CQE2 has 798 pieces in stock. Both are available as new original components in bulk packaging.
