ZW50F15FD1-Z Equivalent & Substitute Parts

Part Overview

The ZW50F15FD1-Z is a snap action SPDT (Single Pole Double Throw) switch manufactured by Honeywell Sensing and Productivity Solutions. This chassis-mounted switch is rated for 5A at 125V AC and features a lever roller actuator with solder lug termination. The product is classified as obsolete, making identification of equivalent and substitute parts essential for system maintenance, repair, and redesign applications where continued component availability is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ZW50F15FD1-Z is determined by strict alignment of the following core electrical and mechanical parameters:

Critical Matching Parameters:

• Circuit configuration (SPDT)
• Switch function (On-Momentary)
• Current rating (5A AC minimum)
• Voltage rating (125V AC minimum)
• Actuator type (Lever, Roller)
• Mounting type (Chassis Mount)
• Termination style (Solder Lug)

The MS0850505F075S1A from E-Switch satisfies all critical matching parameters. Both switches are SPDT snap action devices with identical electrical ratings, actuator configurations, and mounting specifications. Both feature solder lug termination suitable for direct circuit board integration.

Parameter Comparison

Engineering Selection Recommendations

The MS0850505F075S1A is a direct functional substitute for the obsolete ZW50F15FD1-Z. Both switches meet identical electrical specifications (5A at 125V AC, SPDT configuration, On-Momentary function) and share compatible mechanical interfaces (chassis mount, solder lug termination, lever roller actuator).

The MS0850505F075S1A carries active product status from E-Switch, ensuring ongoing availability and supply chain continuity. Both parts maintain RoHS compliance and unlimited moisture sensitivity ratings (MSL 1), supporting modern manufacturing and environmental standards.

Minor variations exist in operating characteristics. The MS0850505F075S1A exhibits slightly higher operating force (75gf versus 72gf) and release force (25gf versus 15gf), with marginally different operating position and pretravel specifications. The E-Switch substitute provides extended electrical life (50,000 cycles versus 10,000 cycles), supporting applications requiring higher cycle counts.

The ZW50F15FD1-Z operates across a wider temperature range (-40°C to 120°C) compared to the MS0850505F075S1A (-25°C to 85°C). Applications requiring operation below -25°C or above 85°C require evaluation of the narrower operating window of the substitute part.

Frequently Asked Questions (FAQ)

Q: Can the MS0850505F075S1A directly replace the ZW50F15FD1-Z in existing circuits?

A: Yes. Both switches share identical circuit configurations (SPDT), electrical ratings (5A at 125V AC), switch functions (On-Momentary), actuator types (lever roller), mounting methods (chassis mount), and termination styles (solder lug). Direct substitution is supported from an electrical and mechanical standpoint.

Q: What are the key differences between these two switches?

A: The primary differences are operating force (75gf versus 72gf), release force (25gf versus 15gf), operating position (0.587" versus 0.571"), pretravel (0.157" versus 0.170"), operating temperature range (-25°C to 85°C versus -40°C to 120°C), electrical life (50,000 versus 10,000 cycles), and mechanical life (1,000,000 versus 2,000,000 cycles). The MS0850505F075S1A provides higher electrical cycle endurance.

Q: Is the MS0850505F075S1A suitable for applications requiring operation below -25°C?

A: No. The MS0850505F075S1A is rated for operation from -25°C to 85°C. Applications requiring operation below -25°C must retain the ZW50F15FD1-Z or identify alternative components with extended low-temperature specifications.

Q: Are both switches RoHS compliant?

A: Yes. The ZW50F15FD1-Z is RoHS Compliant, and the MS0850505F075S1A is ROHS3 Compliant. Both meet current environmental and regulatory requirements for electronic component manufacturing.

Q: What is the packaging difference between these parts?

A: The ZW50F15FD1-Z is supplied in standard packaging, while the MS0850505F075S1A is supplied in bulk packaging. Bulk packaging typically accommodates higher-volume procurement and may affect minimum order quantities and lead times.

Q: Which switch has longer operational life?

A: The MS0850505F075S1A provides superior electrical life (50,000 cycles versus 10,000 cycles), making it suitable for applications with higher switching frequency requirements. The ZW50F15FD1-Z offers higher mechanical life (2,000,000 cycles versus 1,000,000 cycles).
