Substitute Part Grouping Explanation
Substitution eligibility for the LP2S-16S-559-Z is determined by strict alignment with the following critical parameters:
- Circuit Configuration: SPDT topology must be maintained
- Switch Function: On-Momentary operation required
- Voltage Ratings: Minimum 125V AC and 30V DC capability
- Current Rating: Minimum 3A AC/DC capacity
- Mounting Interface: Panel Mount, Snap-In with 16.20mm x 16.20mm square cutout
- Illumination: LED, Green color at 2.1VDC nominal
- Termination: Solder Lug connection
- Regulatory Compliance: ROHS3 Compliant
The substitute part UB15KKW015F-FF (NKK Switches) meets all mandatory substitution criteria. This part maintains identical circuit topology, switch function, voltage ratings, mounting configuration, panel cutout dimensions, illumination specification, termination style, and regulatory compliance status. The substitute part exceeds the current rating requirement (5A versus 3A), which represents an acceptable design margin for electrical performance.

Engineering Selection Recommendations
The UB15KKW015F-FF qualifies as a direct functional substitute for the LP2S-16S-559-Z based on electrical and mechanical parameter alignment. Both parts maintain ROHS3 compliance and are suitable for equivalent circuit implementations.
The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity compared to the obsolete main part. The higher current rating (5A versus 3A) provides additional electrical margin without affecting circuit compatibility.
Temperature range consideration: The substitute part operates to -25°C (5°C lower minimum) but is limited to 50°C maximum versus 60°C for the main part. Applications requiring operation above 50°C require thermal performance evaluation.
Electrical life specification: The main part is rated for 30,000 cycles while the substitute is rated for 10,000 cycles. Applications with high cycle count requirements should account for this difference in maintenance planning.
Frequently Asked Questions (FAQ)
Q: Can UB15KKW015F-FF be used as a direct replacement for LP2S-16S-559-Z in existing designs?
A: Yes, for applications operating within the substitute part's temperature range (-25°C to 50°C) and cycle life requirements (10,000 cycles). The identical panel cutout dimensions, SPDT circuit topology, On-Momentary function, voltage ratings, illumination specification, and solder lug termination enable direct mechanical and electrical substitution.
Q: What is the impact of the higher current rating on the substitute part?
A: The UB15KKW015F-FF is rated for 5A compared to the main part's 3A rating. This represents a design margin increase and does not create compatibility issues. The substitute part will function correctly in circuits designed for 3A operation.
Q: Are there temperature limitations when using the substitute part?
A: The substitute part operates from -25°C to 50°C, compared to the main part's -15°C to 60°C range. Applications requiring operation above 50°C or below -25°C must use the original part or identify alternative substitutes with matching temperature specifications.
Q: How does the electrical life difference affect part selection?
A: The main part is rated for 30,000 cycles while the substitute is rated for 10,000 cycles. For applications with cycle counts exceeding 10,000, maintenance intervals or part replacement schedules should be adjusted accordingly.
Q: Are both parts RoHS compliant?
A: Yes, both LP2S-16S-559-Z and UB15KKW015F-FF are ROHS3 compliant, meeting environmental and regulatory requirements for equivalent use.
Q: What is the packaging difference between these parts?
A: The main part is supplied in standard packaging, while the substitute part is supplied in Bulk packaging. This affects order quantities and handling but does not impact functional performance.
