Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2-1825142-1 toggle switch is determined by electrical and mechanical compatibility across the following critical parameters:

Primary Substitution Criteria:

• Circuit configuration (SPDT required)
• Switch function (On-On operation)
• Mounting type (Through Hole)
• Termination style (PC Pin)
• Actuator type (Standard Round)
• Ingress protection level (IP67 or equivalent)

Electrical Compatibility Parameters:

• Current rating must equal or exceed 5A (AC/DC)
• Voltage rating must support minimum 120V AC and 28V DC
• Operating temperature range must encompass -30°C to 85°C

Mechanical Compatibility Parameters:

• Actuator length tolerance around 12.70mm
• Bushing thread type (Unthreaded)
• PC Pin termination for circuit board mounting

Substitute parts are grouped into two categories: MFR Recommended (direct replacement from TE Connectivity) and Similar (functionally equivalent from alternative manufacturers). Parts within each category maintain the specified electrical and mechanical parameters while accommodating minor variations in actuator length, electrical life, and ingress protection ratings.

Parameter Comparison

Engineering Selection Recommendations

MFR Recommended Substitute: 1-1825142-6

The 1-1825142-6 from TE Connectivity ALCOSWITCH is the primary substitute for the obsolete 2-1825142-1. This part maintains identical electrical specifications (5A at 120V AC and 28V DC), identical actuator length (12.70mm), identical operating temperature range (-30°C to 85°C), and identical electrical life (6,000 cycles). Both parts are ROHS3 compliant and REACH affected. The primary difference is the mounting configuration: the 1-1825142-6 features right-angle through-hole mounting compared to the standard through-hole orientation of the original part. This substitution is appropriate for applications where the right-angle mounting geometry accommodates the circuit board layout. The part is currently active with 864 units in stock.

Similar Substitutes for Electrical Equivalency:

The E101SD1CGE and E101SD1CQE from C&K provide higher current capacity (7.5A) and extended electrical life (40,000 cycles) while maintaining the 120V AC and 28V DC voltage specifications. These parts feature IP57 ingress protection (dust protected, waterproof) compared to the IP67 rating of the original. Both are ROHS3 compliant and REACH affected. The actuator length matches at 12.70mm. These substitutes are suitable for applications requiring enhanced durability and cycle life.

The A123L21D9CQ from Electroswitch offers 6A current capacity at 125V AC with extended electrical life (60,000 cycles). The actuator length is 13.97mm, representing a 1.27mm increase. This part is RoHS compliant with vendor-undefined REACH status. Selection of this substitute requires verification that the increased actuator length accommodates the panel cutout geometry.

Lower-Rated Alternatives:

The A123S1Y9CB (0.5VA at 28V) and E101SD1CBE (0.4VA at 20V) provide reduced electrical ratings and are suitable only for low-power applications. These parts are not recommended as direct substitutes for the 2-1825142-1 in applications requiring 5A at 120V AC operation.

Frequently Asked Questions (FAQ)

Q: Can the 1-1825142-6 directly replace the 2-1825142-1 in existing circuit board designs?

A: The 1-1825142-6 maintains identical electrical specifications and actuator length. However, the right-angle mounting configuration differs from the standard through-hole orientation of the original part. Circuit board layout and panel cutout geometry must accommodate this mounting difference. If the existing design requires standard through-hole orientation, the 1-1825142-6 is not a direct mechanical replacement.

Q: What is the difference between IP67 and IP57 ingress protection ratings?

A: IP67 provides dust-tight and waterproof protection, while IP57 provides dust protection and waterproof protection. The 2-1825142-1 specifies IP67. Substitute parts E101SD1CGE and E101SD1CQE feature IP57 rating. Applications requiring full dust-tight protection should maintain IP67 specification or confirm that IP57 protection is acceptable for the intended environment.

Q: Are the Electroswitch A123 series parts suitable replacements for high-current applications?

A: The A123L21D9CQ provides 6A current capacity, exceeding the 5A rating of the original part. However, the actuator length is 13.97mm compared to 12.70mm for the 2-1825142-1. Panel cutout dimensions and mechanical clearances must accommodate this 1.27mm increase. The A123S1Y9CB is rated for only 0.5VA and is not suitable for applications requiring 5A operation.

Q: What is the significance of electrical life ratings in substitute selection?

A: The 2-1825142-1 specifies 6,000 electrical cycles. Substitute parts from C&K (E101SD1CGE, E101SD1CQE) provide 40,000 cycles, and Electroswitch parts (A123L21D9CQ, A123S1Y9CB) provide 60,000 cycles. Higher electrical life indicates extended operational durability and reduced maintenance requirements. Selection of higher-rated alternatives extends component service life in applications with frequent switching operations.

Q: Are all substitute parts RoHS and REACH compliant?

A: The 2-1825142-1, 1-1825142-6, E101SD1CBE, E101SD1CGE, and E101SD1CQE are ROHS3 compliant and REACH affected. The Electroswitch parts (A123L21D9CQ, A123S1Y9CB) are RoHS compliant with vendor-undefined REACH status. Applications subject to REACH compliance requirements should prioritize parts with confirmed REACH affected status or obtain vendor documentation for Electroswitch components.

Q: Can the lower-rated C&K E101SD1CBE substitute for the 2-1825142-1?

A: The E101SD1CBE is rated for 0.4VA at 20V AC, significantly below the 5A at 120V AC specification of the 2-1825142-1. This part is suitable only for low-power signal switching applications and is not a functional substitute for the original part in standard 5A applications.

Q: What packaging options are available for substitute parts?

A: The 1-1825142-6 is supplied in bulk packaging. The E101SD1CBE and E101SD1CGE are supplied in tray packaging. The Electroswitch A123L21D9CQ is supplied in bulk packaging, while A123S1Y9CB is supplied in bulk packaging. Packaging selection affects inventory management and component handling procedures.
