Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity ALCOSWITCH 1478620-5 is determined by strict alignment of the following critical parameters:

Circuit and Function Compatibility: The substitute part must maintain SPST-NO circuit configuration with Off-Mom switch function to ensure electrical behavior equivalence in the application.

Electrical Ratings: The substitute part must support the required current and voltage specifications. The 1478620-5 operates at 16A AC and 125V AC. Substitute parts must meet or exceed these electrical requirements to function within the original application envelope.

Mechanical Interface: Chassis mount configuration with lever roller actuator type is required for physical compatibility. Operating position of 0.815" (20.7mm) establishes the mechanical stroke requirement.

Termination Compatibility: Quick connect termination style must be compatible with existing connector infrastructure. The 0.250" (6.3mm) terminal size defines the physical connection interface.

Environmental and Lifecycle Parameters: Operating temperature range, electrical life cycles, and mechanical life cycles establish the durability and reliability envelope for the substitute component.

The E-Switch LS085R105F250C1C is identified as a substitute part; however, critical parameter deviations exist that must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The E-Switch LS085R105F250C1C presents significant electrical and mechanical parameter deviations from the TE Connectivity ALCOSWITCH 1478620-5 that preclude direct substitution in applications requiring the original specifications.

Critical Incompatibilities:

The substitute part operates at 0.4VA (AC/DC) with a maximum voltage rating of 20V AC, substantially below the original 16A at 125V AC requirement. This electrical rating reduction eliminates compatibility with standard 125V AC line voltage applications.

The quick connect termination size differs from 0.250" (6.3mm) to 0.187" (4.7mm), creating a physical interface mismatch with existing connector infrastructure.

The operating temperature upper limit of 85°C is reduced from the original 130°C specification, restricting thermal operating envelope.

Electrical life is reduced to 50,000 cycles from 100,000 cycles, and mechanical life is reduced to 1,000,000 cycles from 10,000,000 cycles, indicating substantially lower durability characteristics.

Product Status Consideration:

The TE Connectivity ALCOSWITCH 1478620-5 is classified as obsolete. The E-Switch LS085R105F250C1C maintains active product status with RoHS3 compliance and REACH unaffected certification, indicating current manufacturing availability and regulatory alignment.

For applications where the original electrical and mechanical specifications are mandatory, direct substitution is not feasible. Component redesign or alternative sourcing strategies are required.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch LS085R105F250C1C directly replace the TE Connectivity ALCOSWITCH 1478620-5 in existing applications?

A: No. The E-Switch substitute part has insufficient electrical ratings (0.4VA at 20V versus 16A at 125V), incompatible termination size (0.187" versus 0.250"), reduced operating temperature range (85°C maximum versus 130°C), and reduced cycle life specifications. Direct substitution is not feasible for applications requiring the original electrical and mechanical parameters.

Q: What are the primary compatibility barriers between these two parts?

A: The primary incompatibilities are: (1) electrical rating mismatch—the substitute supports only 0.4VA at 20V compared to 16A at 125V; (2) termination size difference—0.187" (4.7mm) versus 0.250" (6.3mm) quick connect terminals; (3) thermal operating range reduction—maximum 85°C versus 130°C; (4) reduced cycle life—50,000 electrical cycles and 1,000,000 mechanical cycles versus 100,000 and 10,000,000 respectively.

Q: Are the mechanical interfaces compatible between these parts?

A: Partial mechanical compatibility exists. Both parts feature lever roller actuators, chassis mount configuration, and identical 0.815" (20.7mm) operating position. However, the quick connect termination sizes are different (0.250" versus 0.187"), preventing direct physical substitution without connector modification.

Q: What is the significance of the product status difference?

A: The TE Connectivity ALCOSWITCH 1478620-5 is obsolete, indicating discontinued manufacturing and limited availability. The E-Switch LS085R105F250C1C is active with current production and regulatory compliance (RoHS3, REACH unaffected), ensuring ongoing availability and support. However, active status does not address the electrical and mechanical parameter incompatibilities.

Q: Can the operating force difference (350gf versus 250gf) affect application performance?

A: Yes. The reduced operating force requirement of the substitute part (250gf versus 350gf) indicates different actuation characteristics. Applications designed for the original 350gf operating force may experience unintended actuation with the lower-force substitute, particularly in environments with vibration or mechanical stress.

Q: What compliance certifications are relevant for substitution decisions?

A: The E-Switch LS085R105F250C1C holds RoHS3 compliance and REACH unaffected certification, indicating regulatory alignment with current environmental standards. The TE Connectivity ALCOSWITCH 1478620-5 lists REACH unaffected status. Both parts carry EAR99 ECCN classification. Compliance certifications do not override electrical and mechanical parameter incompatibilities.
