Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TFS10ST2040C are identified based on the following electrical and mechanical compatibility criteria:

Primary Substitution Parameters:

• Circuit configuration: SPDT maintained across all substitutes
• Switch function: On-Mom maintained across all substitutes
• Actuator type: Lever, Straight maintained across all substitutes
• Mounting type: Chassis Mount maintained across all substitutes
• Current and voltage ratings: Substitutes rated at 16A AC / 250V AC, which exceeds the original 10A AC / 125V AC specification, providing upward compatibility

Secondary Compatibility Parameters:

• Termination style: Quick Connect maintained, with connector size variation (0.250" vs 0.187")
• Operating temperature range: Substitutes support extended ranges (-25°C to 150°C or -25°C to 125°C)
• Mechanical life: Substitutes rated at 5,000,000 cycles, which is lower than the original 10,000,000 cycles
• RoHS compliance: All substitutes maintain RoHS compliance

The V15H16-CZ300A02-K and V15T16-CZ100A02-K from Honeywell Sensing and Productivity Solutions are functionally equivalent within the allowed parameter tolerances for SPDT snap action switches in chassis mount configurations.

Parameter Comparison

Engineering Selection Recommendations

Both Honeywell substitute parts maintain Active product status with full RoHS compliance and REACH unaffected designation, matching the compliance profile of the TFS10ST2040C.

V15H16-CZ300A02-K Selection Criteria:

• Higher operating force (180gf) and release force (30gf) compared to the original specification
• Extended upper operating temperature limit to 150°C
• Electrical life rating of 50,000 cycles
• Suitable for applications requiring higher actuation force and extended thermal performance

V15T16-CZ100A02-K Selection Criteria:

• Lower operating force (60gf) compared to the original specification
• Release force matches the original 10gf specification
• Operating temperature range to 125°C
• Electrical life rating of 50,000 cycles
• Suitable for applications requiring lower actuation force with maintained release characteristics

Both substitutes provide uprated current and voltage specifications (16A AC / 250V AC), delivering enhanced electrical capacity beyond the original 10A AC / 125V AC rating. Termination connector size differs (0.250" vs 0.187"), requiring mechanical interface verification during integration.

Frequently Asked Questions (FAQ)

Q: Can V15H16-CZ300A02-K or V15T16-CZ100A02-K directly replace TFS10ST2040C without modification?

A: Both Honeywell parts maintain SPDT circuit configuration, On-Mom switch function, Lever Straight actuator, and Chassis Mount configuration. However, termination connector size differs (0.250" vs 0.187"), requiring mechanical interface assessment. Electrical specifications are uprated, providing compatibility within the original application envelope.

Q: What is the primary difference between the two Honeywell substitute options?

A: The V15H16-CZ300A02-K features higher operating force (180gf) and extended temperature range to 150°C. The V15T16-CZ100A02-K features lower operating force (60gf) matching the original release force specification of 10gf. Selection depends on actuation force requirements and thermal operating environment.

Q: How do the mechanical life ratings compare?

A: The original TFS10ST2040C is rated for 10,000,000 mechanical cycles. Both Honeywell substitutes are rated for 5,000,000 mechanical cycles, representing a 50% reduction in cycle life specification. Application duty cycle requirements must be evaluated against this parameter.

Q: Are all parts RoHS compliant?

A: Yes. The TFS10ST2040C is RoHS3 Compliant. Both V15H16-CZ300A02-K and V15T16-CZ100A02-K are RoHS Compliant. All parts maintain REACH unaffected designation.

Q: What packaging considerations apply to these substitutes?

A: The TFS10ST2040C is supplied in Box packaging. Both Honeywell substitutes are supplied in Tray packaging. Inventory availability is 1189 pcs (TFS10ST2040C), 1596 pcs (V15H16-CZ300A02-K), and 856 pcs (V15T16-CZ100A02-K).
