Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1478614-5 is determined by the following critical parameters that must remain consistent or be compatible with the original application:

Critical Matching Parameters:

• Circuit configuration: SPST-NC
• Switch function: On-Mom (Momentary)
• Current rating: 16A (AC)
• Actuator type: Lever, Roller
• Mounting type: Chassis Mount
• Termination style: Quick Connect - 0.250" (6.3mm)

Compatible Variation Parameters:

• Voltage rating: The substitute may exceed the original 125V rating, provided the application does not require voltage derating
• Operating temperature range: Substitute range must encompass or exceed the application requirements
• Electrical and mechanical life cycles: Substitute ratings must meet or exceed application duty cycle requirements

The Honeywell Sensing and Productivity Solutions V15T16-CC100A05-K qualifies as a substitute based on matching circuit configuration, current rating, actuator type, mounting configuration, and termination style. The substitute provides higher voltage rating (250V), lower operating force characteristics, and active product status.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The TE Connectivity 1478614-5 is classified as obsolete. The Honeywell V15T16-CC100A05-K is an active product currently in production, ensuring long-term availability and supply chain continuity.

Compliance and Certification: The Honeywell substitute is RoHS Compliant, meeting current environmental and regulatory standards. Both parts share identical ECCN (EAR99) and HTSUS (8536.50.9040) classifications, indicating equivalent regulatory treatment.

Electrical Performance: Both switches maintain identical circuit configuration (SPST-NC), current rating (16A AC), and momentary function. The substitute's higher voltage rating (250V versus 125V) provides design margin for 125V applications without derating.

Mechanical Compatibility: Mounting type, termination style, and physical dimensions are functionally equivalent. Operating position, pretravel, differential travel, and overtravel measurements are identical or negligibly different (0.003" variance in operating position).

Operational Characteristics: The substitute exhibits lower operating force (120gf versus 350gf) and lower release force (20gf versus 70gf). Applications requiring specific actuation force characteristics must evaluate this difference against system requirements.

Life Cycle Ratings: The substitute provides 50% of the electrical life (50,000 versus 100,000 cycles) and 50% of the mechanical life (5,000,000 versus 10,000,000 cycles). Applications with high-cycle duty requirements must confirm the substitute meets expected service life.

Temperature Range: The substitute's operating range (-25°C to 125°C) differs slightly from the original (-20°C to 130°C). Applications operating at temperatures below -25°C or above 125°C require the original specification or alternative sourcing.

Frequently Asked Questions (FAQ)

Q: Can the Honeywell V15T16-CC100A05-K directly replace the TE Connectivity 1478614-5 in existing designs?

A: Direct mechanical and electrical replacement is possible for applications operating within the substitute's specifications. The identical circuit configuration, current rating, actuator type, mounting configuration, and termination style ensure physical and functional compatibility. However, applications must verify that lower operating force requirements, reduced life cycle ratings, and slightly different temperature range limits do not conflict with system requirements.

Q: What is the primary difference in operating force between these two switches?

A: The TE Connectivity 1478614-5 requires 350gf operating force and 70gf release force. The Honeywell V15T16-CC100A05-K requires 120gf operating force and 20gf release force. Applications with mechanical linkages or actuators designed for specific force characteristics must evaluate this difference to ensure proper switch engagement and release.

Q: Are the electrical ratings compatible for 125V AC applications?

A: Yes. The Honeywell substitute is rated for 250V AC, which exceeds the original 125V AC requirement. A 250V-rated switch operates safely at 125V without derating. Both switches maintain identical 16A AC current rating.

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

A: The TE Connectivity 1478614-5 provides 100,000 electrical cycles and 10,000,000 mechanical cycles. The Honeywell substitute provides 50,000 electrical cycles and 5,000,000 mechanical cycles. Applications with high-frequency switching or extended service life requirements must confirm the substitute's reduced cycle ratings meet expected duty cycle demands.

Q: How do the temperature operating ranges differ?

A: The TE Connectivity 1478614-5 operates from -20°C to 130°C. The Honeywell V15T16-CC100A05-K operates from -25°C to 125°C. The substitute extends the lower temperature limit by 5°C but reduces the upper temperature limit by 5°C. Applications operating at extreme temperatures must verify compatibility with the substitute's range.

Q: Is the Honeywell substitute RoHS compliant?

A: Yes. The Honeywell V15T16-CC100A05-K is RoHS Compliant. The TE Connectivity 1478614-5 RoHS status is not specified. For applications requiring RoHS compliance, the Honeywell substitute meets this requirement.

Q: Are the physical dimensions and mounting interfaces identical?

A: Operating position, pretravel, differential travel, and overtravel measurements are identical or functionally equivalent (maximum variance 0.003"). Both switches use chassis mount configuration with Quick Connect 0.250" (6.3mm) termination. Physical compatibility is confirmed for direct substitution in existing mechanical assemblies.

Q: What is the packaging difference between these parts?

A: The TE Connectivity 1478614-5 packaging is not specified. The Honeywell V15T16-CC100A05-K is supplied in Tray packaging. Packaging differences do not affect functional compatibility but may impact receiving, storage, and handling procedures.

Q: Why is the TE Connectivity part listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The Honeywell V15T16-CC100A05-K maintains active product status, ensuring continued availability, technical support, and supply chain reliability for new designs and ongoing maintenance applications.
