Key Parameters

Substitute Part Grouping Explanation

Substitution of the LP1S-17S-559-Z is determined by strict alignment of the following critical parameters:

• Circuit Configuration: SPDT (Single Pole Double Throw) with On-On switching function
• Voltage Ratings: Minimum 125V AC and 30V DC capability
• Current Rating: Minimum 3A AC/DC capacity
• Mounting Interface: Through Hole with PC Pin termination
• Actuator Specification: Square button configuration with green color
• Illumination: LED type with green color and 2.1 VDC nominal voltage
• Environmental Compliance: ROHS3 compliance and MSL 1 rating

The substitute part UB16SKW035F-FF from NKK Switches meets all mandatory substitution criteria. This part maintains electrical equivalence while offering enhanced mechanical durability and active product status.

Parameter Comparison

Engineering Selection Recommendations

The UB16SKW035F-FF qualifies as a direct substitute for the obsolete LP1S-17S-559-Z based on electrical and mechanical equivalence across all critical parameters. Both components maintain identical voltage ratings (125V AC / 30V DC), SPDT circuit configuration, and illumination specifications (LED, green, 2.1 VDC).

The substitute part offers superior current capacity (5A versus 3A), providing design margin for applications operating at or near the original component's rated current. The UB16SKW035F-FF maintains active product status with established supply availability, eliminating obsolescence risk.

Both components satisfy ROHS3 compliance and MSL 1 moisture sensitivity requirements. The substitute's process-sealed design and extended mechanical life (200,000 cycles) support long-term reliability in industrial control applications.

Frequently Asked Questions (FAQ)

Q: Can the UB16SKW035F-FF directly replace the LP1S-17S-559-Z in existing designs?

A: Yes. Both components share identical SPDT circuit configuration, voltage ratings (125V AC / 30V DC), illumination specifications (LED, green, 2.1 VDC), and PC Pin through-hole termination. Physical mounting and electrical interface compatibility is maintained.

Q: What are the differences in electrical life ratings?

A: The LP1S-17S-559-Z specifies 30,000 electrical cycles, while the UB16SKW035F-FF specifies 10,000 electrical cycles. However, the substitute provides 200,000 mechanical cycles compared to the main part's unspecified mechanical life, indicating enhanced overall durability for mechanical switching operations.

Q: Does the higher current rating of the substitute affect compatibility?

A: No. The UB16SKW035F-FF's 5A rating exceeds the original 3A requirement, providing additional design margin without affecting circuit operation. Applications designed for 3A operation remain fully compatible.

Q: Are there temperature range considerations for substitution?

A: The LP1S-17S-559-Z operates from -15°C to 60°C, while the UB16SKW035F-FF operates from -25°C to 50°C. The substitute provides extended low-temperature capability but reduced high-temperature range. Verify application operating conditions fall within -25°C to 50°C for full compatibility.

Q: What packaging differences exist between these components?

A: The LP1S-17S-559-Z packaging is not specified. The UB16SKW035F-FF is supplied in Tray packaging. Verify tray packaging compatibility with assembly and handling processes.

Q: Are both components RoHS compliant?

A: Yes. Both the LP1S-17S-559-Z and UB16SKW035F-FF are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting environmental and regulatory requirements for industrial applications.
