TE Connectivity ALCOSWITCH 1478612-5 Equivalent & Substitute Parts

Part Overview

The TE Connectivity ALCOSWITCH 1478612-5 is a snap-action switch with SPST-NC (Single Pole Single Throw - Normally Closed) circuit configuration, rated for 16A at 125V AC. This switch features a lever roller actuator and chassis mount termination using quick connect 0.250" (6.3mm) terminals. The product is classified as obsolete, making identification of equivalent substitute parts necessary for ongoing system maintenance and new design implementations where this switch type is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1478612-5 is determined by the following critical parameters that must remain consistent or be compatible with the original application:

Core Compatibility Parameters:

• Circuit configuration: SPST-NC
• Switch function: On-Mom (momentary operation)
• Current rating: 16A (AC) minimum
• Actuator type: Lever with roller mechanism
• Mounting type: Chassis mount
• Termination style: Quick connect 0.250" (6.3mm) terminals

Allowable Variations:

• Voltage rating may exceed 125V (higher voltage rating provides backward compatibility)
• Operating temperature range may differ if it encompasses the original range
• Electrical and mechanical life cycles may vary based on application duty cycle requirements
• Product status may transition from obsolete to active

The substitute part Honeywell V15T16-CC100A05-K satisfies all core compatibility parameters while providing enhanced voltage rating (250V) and active product status.

Engineering Selection Recommendations

Primary Substitute: Honeywell V15T16-CC100A05-K

The Honeywell V15T16-CC100A05-K is the qualified substitute for the obsolete TE Connectivity 1478612-5. Selection of this substitute is supported by the following engineering factors:

Product Status Alignment: The Honeywell part maintains active manufacturing status, ensuring long-term availability and supply chain continuity compared to the obsolete TE Connectivity original.

Electrical Compliance: Both parts carry identical ECCN (EAR99) and HTSUS (8536.50.9040) classifications, confirming regulatory equivalence for export and tariff purposes.

Functional Compatibility: The substitute maintains identical circuit configuration (SPST-NC), switch function (On-Mom), current rating (16A AC), actuator type (lever roller), mounting type (chassis mount), and termination style (quick connect 0.250"). These parameters ensure direct functional replacement in existing applications.

Voltage Rating Enhancement: The substitute's 250V AC rating exceeds the original 125V specification, providing backward compatibility for 125V applications while enabling use in higher voltage systems.

Mechanical Characteristics: Operating position, pretravel, differential travel, and overtravel measurements are effectively identical between the two parts, confirming mechanical interchangeability.

Compliance Certification: The Honeywell substitute is RoHS compliant, meeting modern environmental and regulatory standards not specified for the obsolete TE Connectivity original.

Operational Considerations: The substitute requires lower operating force (120gf versus 140gf), which may reduce actuator fatigue in high-cycle applications. The electrical life (50,000 cycles) and mechanical life (5,000,000 cycles) are rated at 50% of the original specification; application duty cycle analysis is required to confirm suitability for specific use cases.

Frequently Asked Questions (FAQ)

Q: Can the Honeywell V15T16-CC100A05-K directly replace the TE Connectivity 1478612-5 in existing assemblies?

A: Yes. Both switches share identical circuit configuration (SPST-NC), current rating (16A AC), actuator type (lever roller), mounting type (chassis mount), and termination style (quick connect 0.250"). The mechanical dimensions are effectively equivalent, enabling direct substitution in existing mechanical and electrical designs.

Q: What is the significance of the voltage rating difference (125V versus 250V)?

A: The Honeywell substitute's higher voltage rating (250V) is compatible with the original 125V application. A higher voltage rating indicates the switch can safely operate at the original voltage level with additional margin. No circuit modifications are required when substituting into a 125V system.

Q: How do the operating force differences affect application suitability?

A: The Honeywell substitute requires 120gf operating force compared to the original 140gf. This 20gf reduction may benefit applications requiring lighter actuation, but does not affect electrical performance. Mechanical linkage or actuator design must accommodate this force difference if precise actuation characteristics are critical.

Q: Are there packaging differences between these parts?

A: The TE Connectivity original is packaged in standard format (packaging not specified). The Honeywell substitute is supplied in trays. Packaging differences do not affect electrical or mechanical compatibility; they impact only handling, storage, and inventory management procedures.

Q: What is the impact of the electrical life rating difference (100,000 versus 50,000 cycles)?

A: The Honeywell substitute is rated for 50,000 electrical cycles compared to the original 100,000 cycles. Application duty cycle analysis is required to confirm suitability. For applications operating below 50,000 cycles over the product lifetime, this difference is not limiting. For higher-cycle applications, alternative parts or design modifications may be necessary.

Q: Does the operating temperature range difference affect compatibility?

A: The Honeywell substitute operates from -25°C to 125°C compared to the original -20°C to 130°C. The substitute's lower temperature limit extends 5°C below the original, while the upper limit is 5°C lower. For applications operating within -20°C to 125°C, the substitute is fully compatible. Applications requiring operation above 125°C or below -25°C require alternative solutions.

Q: Is the Honeywell V15T16-CC100A05-K RoHS compliant?

A: Yes. The Honeywell substitute is RoHS compliant, meeting Restriction of Hazardous Substances requirements. The original TE Connectivity part's RoHS status is not specified. For applications requiring RoHS compliance, the Honeywell substitute satisfies this requirement.

Q: What is the inventory status of these parts?

A: The TE Connectivity 1478612-5 has 824 pieces in stock as new original inventory. The Honeywell V15T16-CC100A05-K has 1,149 pieces in stock. Both parts are available for immediate procurement.
