Substitute Part Grouping Explanation
Substitution of the TE Connectivity 1478607-2 is determined by the following critical parameters:
Primary Substitution Criteria:
- Circuit configuration (SPDT)
- Switch function (On-Mom)
- Current rating (16A AC minimum)
- Voltage rating (125V AC minimum)
- Mounting type (Chassis Mount)
- Termination style (Quick Connect - 0.250")
- Actuator type (Lever, Straight preferred for form factor compatibility)
Secondary Compatibility Factors:
- Operating force and release force ranges

Engineering Selection Recommendations
Recommended Primary Substitute: V7-1C17E9-002
The Honeywell V7-1C17E9-002 is the closest functional equivalent to the TE Connectivity 1478607-2. This part maintains identical circuit configuration (SPDT), switch function (On-Mom), actuator type (Lever, Straight), mounting type (Chassis Mount), and termination style (Quick Connect - 0.250"). The part is rated for 15A AC at 125V, which is within acceptable tolerance for 16A applications. The V7-1C17E9-002 is active in production status with RoHS compliance and 100,000 electrical cycle rating matching the original part. Operating temperature range is -40°C to 85°C, which covers the lower end of the original specification but may be limiting for applications requiring operation above 85°C.
Alternative Substitutes for Higher Voltage Applications: V15H16-CZ100-K and V15T16-CZ100-K
The Honeywell V15 series switches (V15H16-CZ100-K and V15T16-CZ100-K) provide 16A AC rating at 250V, offering enhanced voltage capability. Both parts feature chassis mount configuration with Quick Connect - 0.250" termination. The primary difference from the original part is the round pin plunger actuator instead of lever straight. These parts are suitable for applications where higher voltage rating is required and actuator form factor is not a constraint. Both are active production parts with RoHS compliance.
Alternative Substitute for Lower Operating Force Applications: LS0851501F100C1A
The E-Switch LS0851501F100C1A provides SPDT on-momentary operation at 15A AC, 125V with lever straight actuator and chassis mount. This part features Quick Connect - 0.187" termination, which differs from the original 0.250" specification and requires connector compatibility verification. Operating force is 100gf compared to the original 200gf, making this suitable for applications requiring lighter actuation. The part is ROHS3 compliant and active in production.
Consideration for Extended Temperature Range: V3L-3296
The Honeywell V3L-3296 provides 15A AC at 125V with lever straight actuator and chassis mount configuration. This part features solder lug termination rather than quick connect, requiring circuit board integration rather than connector-based installation. Operating temperature range is not specified in available data. This part is suitable only for applications where solder lug termination is acceptable.
All recommended substitutes are active production parts with current compliance certifications (RoHS, REACH Unaffected, EAR99).
Frequently Asked Questions (FAQ)
Q: Can the V7-1C17E9-002 directly replace the 1478607-2 in existing applications?
A: The V7-1C17E9-002 is functionally compatible for applications operating within -40°C to 85°C temperature range. The part maintains identical circuit configuration, actuator type, mounting type, and termination style. Current rating is 15A AC versus the original 16A AC, which is acceptable for most applications. Electrical life rating (100,000 cycles) matches the original specification. Verify that your application does not require operation above 85°C, as the V7-1C17E9-002 is limited to this upper temperature boundary.
Q: What is the difference between the V15H16-CZ100-K and V15T16-CZ100-K?
A: Both parts are rated for 16A AC at 250V with identical electrical and mechanical specifications. The primary difference is operating temperature range: V15H16-CZ100-K operates from -25°C to 150°C, while V15T16-CZ100-K operates from -25°C to 125°C. Both feature round pin plunger actuators instead of lever straight, requiring mechanical form factor evaluation for your application.
Q: Why does the LS0851501F100C1A have a different termination size (0.187" vs 0.250")?
A: The LS0851501F100C1A uses Quick Connect - 0.187" (4.7mm) termination, while the original 1478607-2 uses Quick Connect - 0.250" (6.3mm). These are different connector standards and are not interchangeable. Connector compatibility must be verified before selecting this substitute. The 0.187" connector is a smaller form factor commonly used in compact applications.
Q: Is the V3L-3296 suitable as a substitute?
A: The V3L-3296 is functionally compatible for SPDT on-momentary operation at 15A AC, 125V. However, this part uses solder lug termination instead of quick connect, requiring direct circuit board soldering rather than connector-based installation. This substitute is appropriate only for applications where solder lug termination is acceptable and the original quick connect interface is not required.
Q: What are the key parameters that determine substitution compatibility?
A: Substitution compatibility is determined by: (1) Circuit configuration (SPDT), (2) Switch function (On-Mom), (3) Current rating (minimum 16A AC or acceptable lower rating for your application), (4) Voltage rating (minimum 125V AC), (5) Mounting type (Chassis Mount), (6) Termination style (Quick Connect - 0.250" for direct replacement), and (7) Actuator type (Lever, Straight for form factor compatibility). Operating force, release force, and temperature range should be evaluated based on specific application requirements.
Q: Can I use a 15A rated switch in place of a 16A rated switch?
A: A 15A rated switch can be used in applications where the actual current draw does not exceed 15A. If your application requires the full 16A capacity, a 15A substitute is not appropriate. Verify actual circuit current requirements before selecting a lower-rated substitute.
Q: What is the significance of the operating temperature range difference?
A: The original 1478607-2 operates from -20°C to 130°C. The V7-1C17E9-002 operates from -40°C to 85°C. If your application requires operation above 85°C, the V7-1C17E9-002 is not suitable. The Honeywell V15 series switches extend to 150°C (V15H16-CZ100-K) or 125°C (V15T16-CZ100-K), making them appropriate for high-temperature applications.
Q: Are all substitute parts RoHS compliant?
A: Yes, all active production substitute parts listed (V7-1C17E9-002, V15H16-CZ100-K, V15T16-CZ100-K, LS0851501F100C1A, and V3L-3296) are RoHS compliant. The original 1478607-2 does not specify RoHS status due to its obsolete classification.
Q: What does "On-Mom" switch function mean?
A: "On-Mom" (On-Momentary) indicates that the switch maintains a closed contact in one position and returns to the open position when the actuator is released. This is standard momentary switch operation used in applications requiring temporary circuit activation.
