Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity ALCOSWITCH 1825082-1 is determined by strict alignment of the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Circuit configuration must be SPDT
• Contact timing must be non-shorting (BBM)
• Switch function must be on-on
• Voltage rating must support 125V AC operation
• Current rating must equal or exceed 500mA AC
• Mounting type must be through-hole compatible
• Contact material and finish must support equivalent electrical performance

Secondary Compatibility Factors:

• Operating temperature range must encompass or exceed -20°C to 85°C
• Mechanical and electrical life ratings should support equivalent application duty cycles
• Termination style compatibility with circuit board design

The NKK Switches CS12ANW03 meets the primary substitution criteria with equivalent SPDT non-shorting configuration and on-on switching function at 125V AC. The CS12ANW03 provides enhanced current capacity (3A AC versus 500mA AC) and superior mechanical life (50,000 cycles versus 10,000 cycles), making it suitable for direct substitution in applications requiring the original 1825082-1 performance envelope.

Parameter Comparison

Engineering Selection Recommendations

The NKK Switches CS12ANW03 is a direct functional substitute for the obsolete TE Connectivity ALCOSWITCH 1825082-1. Both components share identical circuit topology (SPDT), contact timing (non-shorting BBM), switching function (on-on), and voltage rating (125V AC). The CS12ANW03 provides superior electrical and mechanical performance characteristics, including higher current capacity (3A versus 500mA), extended mechanical life (50,000 versus 10,000 cycles), and extended electrical life (20,000 versus 6,000 cycles).

Product Status Consideration: The 1825082-1 is classified as obsolete, while the CS12ANW03 maintains active product status with full manufacturer support and availability. The CS12ANW03 is RoHS3 compliant and REACH unaffected, meeting current regulatory requirements for new designs and production.

Termination Compatibility: The primary design consideration is termination style. The original 1825082-1 uses solder turret termination, while the CS12ANW03 uses PC pin termination. Circuit board layout and pad design must accommodate the PC pin configuration. Both components are through-hole mounted and compatible with standard PCB assembly processes.

Thermal and Mechanical Envelope: The CS12ANW03 operates across an extended temperature range (-30°C to 85°C) compared to the 1825082-1 (-20°C to 85°C), providing additional margin for demanding thermal environments. Actuator length differs (5.10mm versus 3.20mm) and switch travel differs (2.20mm versus 2.69mm); mechanical clearance verification is required during board layout design.

Frequently Asked Questions (FAQ)

Q: Can the NKK Switches CS12ANW03 directly replace the TE Connectivity 1825082-1 in existing designs?

A: The CS12ANW03 provides electrical and functional equivalence for SPDT non-shorting on-on switching at 125V AC. However, termination style differs (PC pin versus solder turret), requiring circuit board pad redesign. Actuator dimensions also differ, necessitating mechanical clearance verification. Electrical performance is fully compatible.

Q: What is the significance of the higher current rating on the CS12ANW03?

A: The CS12ANW03 is rated for 3A AC compared to the 1825082-1 at 500mA AC. This higher rating provides design margin and allows the substitute to handle applications with current demands up to 3A without derating. Applications requiring only 500mA operate well within the CS12ANW03 performance envelope.

Q: Are there termination compatibility issues between these two switches?

A: Yes. The 1825082-1 uses solder turret termination designed for direct solder connection to PCB pads. The CS12ANW03 uses PC pin termination, which requires through-hole pads compatible with standard 0.032-inch diameter pins. PCB redesign is necessary to accommodate the different termination style.

Q: How do the mechanical life ratings compare?

A: The 1825082-1 is rated for 10,000 mechanical cycles, while the CS12ANW03 is rated for 50,000 cycles. The CS12ANW03 provides five times greater mechanical durability, making it suitable for high-cycle applications and providing extended service life in equivalent applications.

Q: What is the operating temperature difference between these components?

A: The 1825082-1 operates from -20°C to 85°C, while the CS12ANW03 operates from -30°C to 85°C. The CS12ANW03 provides an additional 10°C of low-temperature capability, making it suitable for cold-environment applications where the original component may not be rated.

Q: Are there regulatory compliance differences?

A: The 1825082-1 is obsolete with no current compliance certifications listed. The CS12ANW03 is active production with RoHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements for new product designs and manufacturing.

Q: What packaging differences exist between these switches?

A: The 1825082-1 packaging information is not specified in available data. The CS12ANW03 is supplied in tray packaging suitable for automated assembly processes. Packaging compatibility should be verified based on production assembly requirements.

Q: Can the CS12ANW03 be used in applications where the 1825082-1 was previously specified?

A: Electrical substitution is valid for applications requiring SPDT non-shorting on-on switching at 125V AC with current demands up to 500mA. Circuit board redesign is required to accommodate PC pin termination and different actuator dimensions. Mechanical clearance and electrical performance must be verified for the specific application.
