Key Parameters

Substitute Part Grouping Explanation

The UB16SKW035D-DD from NKK Switches qualifies as a functional substitute based on the following critical parameters:

Matching Parameters:

• Circuit configuration: SPDT
• Switch function: On-On
• Voltage rating - AC: 125V
• Voltage rating - DC: 30V
• Mounting type: Through Hole
• Actuator type: Square, Button
• Illumination type: LED
• Termination style: PC Pin
• RoHS compliance: ROHS3 Compliant
• MSL rating: 1 (Unlimited)

Differing Parameters:

• Current rating: 5A (UB16SKW035D-DD) versus 3A (LP1S-17S-889-Z)
• Illumination color: Amber (UB16SKW035D-DD) versus Yellow (LP1S-17S-889-Z)
• Illumination voltage: 2 VDC (UB16SKW035D-DD) versus 2.2 VDC (LP1S-17S-889-Z)
• Operating temperature: -25°C to 50°C (UB16SKW035D-DD) versus -15°C to 60°C (LP1S-17S-889-Z)
• Mechanical life: 200,000 cycles (UB16SKW035D-DD) versus not specified (LP1S-17S-889-Z)
• Electrical life: 10,000 cycles (UB16SKW035D-DD) versus 30,000 cycles (LP1S-17S-889-Z)
• Product status: Active (UB16SKW035D-DD) versus Obsolete (LP1S-17S-889-Z)

Parameter Comparison

Engineering Selection Recommendations

The UB16SKW035D-DD is suitable as a substitute for the obsolete LP1S-17S-889-Z in applications where the following conditions are met:

1. Current Capacity: The UB16SKW035D-DD supports 5A, exceeding the original 3A requirement. This provides additional margin for current-carrying capacity.

2. Voltage Compatibility: Both parts maintain identical AC (125V) and DC (30V) voltage ratings, ensuring direct electrical compatibility.

3. Regulatory Compliance: Both parts are ROHS3 Compliant with MSL rating 1 (Unlimited), meeting environmental and moisture sensitivity requirements.

4. Active Product Status: The UB16SKW035D-DD is an active product from NKK Switches, ensuring ongoing availability and supply chain continuity.

5. Illumination Considerations: The UB16SKW035D-DD uses amber LED illumination at 2 VDC versus the original yellow LED at 2.2 VDC. Visual indicator color and voltage differences must be evaluated against system requirements.

6. Operating Temperature: The UB16SKW035D-DD operates within -25°C to 50°C, which is narrower than the original -15°C to 60°C range. Applications requiring operation above 50°C or below -25°C require alternative evaluation.

7. Electrical Life: The UB16SKW035D-DD specifies 10,000 electrical cycles versus the original 30,000 cycles. Applications with high cycle count requirements should assess this difference.

Frequently Asked Questions (FAQ)

Q: Can the UB16SKW035D-DD directly replace the LP1S-17S-889-Z without PCB modifications?

A: Yes, both parts share identical mounting type (Through Hole), actuator type (Square, Button), and termination style (PC Pin). No PCB layout changes are required. However, illumination color and voltage differences must be considered for system integration.

Q: What is the impact of the higher current rating on the UB16SKW035D-DD?

A: The 5A rating of the UB16SKW035D-DD exceeds the original 3A requirement. This provides additional safety margin and does not create compatibility issues in circuits designed for 3A operation.

Q: Are there any temperature range limitations when substituting?

A: The UB16SKW035D-DD operates within -25°C to 50°C, which is narrower than the original -15°C to 60°C range. Applications requiring operation above 50°C or below -25°C must be evaluated separately.

Q: How does the illumination voltage difference affect circuit design?

A: The UB16SKW035D-DD requires 2 VDC illumination versus the original 2.2 VDC. Existing illumination circuits must be verified for compatibility. The 0.2 VDC difference may require minor adjustments to current-limiting resistors.

Q: What is the significance of the electrical life difference?

A: The UB16SKW035D-DD specifies 10,000 electrical cycles versus the original 30,000 cycles. Applications with high switching frequency or extended operational life requirements should assess whether this reduced cycle rating meets system specifications.

Q: Does the amber illumination color affect system functionality?

A: Illumination color is a visual indicator characteristic. The amber LED of the UB16SKW035D-DD differs from the original yellow LED. System requirements for indicator color must be evaluated independently.

Q: Are both parts RoHS compliant?

A: Yes, both the LP1S-17S-889-Z and UB16SKW035D-DD are ROHS3 Compliant with MSL rating 1 (Unlimited), meeting environmental and regulatory requirements.
