Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity ALCOSWITCH 1825162-1 is based on electrical and mechanical compatibility within the following critical parameters:

Electrical Compatibility Requirements:

• Circuit configuration: SP3T
• Contact timing: Shorting (MBB)
• Switch function: On-On-On
• Current rating: 300mA AC minimum
• Voltage rating: 125V AC minimum

Mechanical Compatibility Requirements:

• Mounting type: Through Hole, Right Angle
• Termination style: PC Pin
• Contact material: Copper Alloy with Silver finish
• Actuator material: Polyoxymethylene (Acetal)

The substitute part TE Connectivity ALCOSWITCH 1825260-1 meets all electrical and mechanical compatibility criteria. Both components share identical circuit topology, current and voltage ratings, contact materials, and mounting configurations. Differences in actuator length, switch travel, operating force, and mechanical life do not preclude substitution when the application requirements fall within the specified operating parameters of both components.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity ALCOSWITCH 1825162-1 and 1825260-1 are classified as obsolete products. Selection between these components should be based on the following engineering criteria:

Electrical Performance: Both parts are electrically equivalent for SP3T switching applications at 300mA AC and 125V AC ratings. No electrical performance differentiation exists.

Mechanical Considerations: The substitute part 1825260-1 features a longer actuator (8.50mm versus 4.00mm), higher operating force (600gf versus 250gf), and reduced switch travel (2.00mm versus 2.50mm). These differences require verification against specific mechanical interface requirements and user actuation preferences in the target application.

Environmental and Compliance: The substitute part 1825260-1 provides extended operating temperature range (-20°C to 85°C versus -10°C to 60°C) and ROHS3 compliance certification. Applications requiring enhanced environmental performance or regulatory compliance benefit from the substitute part specifications.

Reliability: The substitute part 1825260-1 demonstrates superior mechanical life rating (15,000 cycles versus 10,000 cycles) and includes specified electrical life rating (15,000 cycles), providing enhanced reliability metrics for high-cycle applications.

Frequently Asked Questions (FAQ)

Q: Can the 1825260-1 directly replace the 1825162-1 in existing designs?

A: Direct replacement is possible from an electrical standpoint, as both parts share identical SP3T circuit configuration, 300mA AC current rating, and 125V AC voltage rating. However, mechanical interface compatibility must be verified. The substitute part features a longer actuator (8.50mm versus 4.00mm) and higher operating force (600gf versus 250gf), which may require design modifications to accommodate the different physical characteristics and actuation requirements.

Q: What are the key electrical parameters that define substitution compatibility?

A: Electrical substitution compatibility is determined by circuit configuration (SP3T), contact timing (Shorting MBB), switch function (On-On-On), current rating (300mA AC minimum), and voltage rating (125V AC minimum). Both parts meet these criteria identically.

Q: Are there differences in contact material or finish between these parts?

A: No. Both parts utilize copper alloy contacts with silver finish, ensuring identical electrical contact characteristics and corrosion resistance properties.

Q: What packaging differences exist between these parts?

A: The main part 1825162-1 is specified with standard packaging, while the substitute part 1825260-1 is supplied in bulk packaging. This distinction affects inventory management and component handling but does not impact electrical or mechanical performance.

Q: How do the operating temperature ranges differ?

A: The main part operates within -10°C to 60°C, while the substitute part operates within -20°C to 85°C. Applications requiring extended temperature performance benefit from the substitute part's wider operating range.

Q: What is the significance of the different mechanical life ratings?

A: The main part specifies 10,000 mechanical cycles, while the substitute part specifies 15,000 mechanical cycles. Applications requiring extended operational life or frequent actuation cycles benefit from the substitute part's enhanced mechanical life rating.

Q: Does the substitute part include electrical life specification?

A: Yes. The substitute part 1825260-1 specifies 15,000 cycles electrical life, while the main part does not provide this specification. This additional rating provides enhanced reliability documentation for electrical switching performance.

Q: Is RoHS compliance a factor in substitution decisions?

A: The substitute part 1825260-1 carries ROHS3 compliance certification, while the main part does not specify RoHS status. Applications subject to RoHS regulatory requirements should utilize the substitute part to ensure compliance.
