Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity ALCOSWITCH 1825405-2 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Circuit configuration: SPST-NO
• Current rating: 3A (AC) minimum
• Voltage rating: 125V AC minimum
• Switch function: Off-Mom (momentary operation)

Mechanical Equivalence Requirements:

• Mounting type: Panel Mount, Rear
• Termination style: Solder Lug
• Actuator type: Round, Button
• Actuator color: Red
• Panel cutout: Circular configuration

Compliance Requirements:

• REACH Status: REACH Unaffected
• ECCN: EAR99

The E-Switch PS1024ALRED satisfies all critical electrical and mechanical parameters, with documented active product status and full compliance certification. Dimensional variations in panel cutout diameter (7.20mm versus 6.35mm) and operating temperature range extensions represent design improvements in the substitute component.

Parameter Comparison

Engineering Selection Recommendations

The E-Switch PS1024ALRED serves as the functional equivalent for the obsolete TE Connectivity ALCOSWITCH 1825405-2. Selection of this substitute is supported by the following engineering factors:

Product Status Alignment: The PS1024ALRED maintains active production status, ensuring long-term component availability and supply chain continuity. The original 1825405-2 is classified as obsolete, making transition to an active equivalent necessary for ongoing procurement.

Electrical Performance: Both components deliver identical electrical specifications: SPST-NO circuit, 3A AC current rating, and 125V AC voltage rating. Momentary switch function is preserved across both designs.

Mechanical Compatibility: Panel mount rear configuration with solder lug termination is maintained. Red round button actuator specifications are identical. Panel cutout diameter increases from 6.35mm to 7.20mm, requiring panel modification or use of adapter hardware in existing installations.

Compliance Certification: Both components carry REACH Unaffected status and EAR99 ECCN classification. The PS1024ALRED includes RoHS3 compliance certification, providing enhanced environmental regulatory alignment.

Operating Envelope: The PS1024ALRED extends the operating temperature range to -20°C to 65°C, providing improved performance in temperature-extreme applications. Electrical life specification decreases from 20,000 cycles to 6,000 cycles; application duty cycle assessment is required to confirm adequacy for intended use.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch PS1024ALRED directly replace the TE Connectivity 1825405-2 without modification?

A: Electrical and functional replacement is direct. Mechanical installation requires panel cutout diameter adjustment from 6.35mm to 7.20mm. Existing panel openings must be enlarged or adapter hardware must be employed.

Q: What is the primary reason for substitution?

A: The TE Connectivity ALCOSWITCH 1825405-2 is classified as obsolete. The E-Switch PS1024ALRED is an active production component with equivalent electrical and mechanical specifications, ensuring continued component availability.

Q: Are the electrical ratings identical between these components?

A: Yes. Both components are rated for 3A AC at 125V AC with SPST-NO circuit configuration and momentary (Off-Mom) switch function.

Q: What is the significance of the electrical life difference?

A: The original component specifies 20,000 electrical cycles; the substitute specifies 6,000 cycles. Application duty cycle must be evaluated to confirm the substitute meets operational requirements. Lower cycle ratings are acceptable for applications with infrequent actuation.

Q: Does the extended operating temperature range of the PS1024ALRED provide any advantage?

A: The PS1024ALRED operates from -20°C to 65°C compared to the original -10°C to 60°C range. This extended envelope provides improved performance in temperature-extreme environments, though both ranges are suitable for standard industrial applications.

Q: Are there compliance or certification differences?

A: Both components are REACH Unaffected and classified as EAR99. The PS1024ALRED includes RoHS3 compliance certification, providing additional environmental regulatory alignment not specified for the original component.

Q: What packaging format is available for the PS1024ALRED?

A: The E-Switch PS1024ALRED is supplied in bulk packaging, with 4,684 pieces currently in stock inventory.
