Key Parameters

Substitute Part Grouping Explanation

The UB16SKW03N-F qualifies as a direct functional equivalent to the UB16SKW03F based on the following critical parameters:

Electrical Compatibility:

• Identical circuit configuration (SPDT)
• Identical switch function (On-On)
• Identical current rating (5A AC/DC)
• Identical voltage ratings (125V AC, 30V DC)

Mechanical Compatibility:

• Identical mounting type (Through Hole)
• Identical actuator type (Square, Button)
• Identical actuator color (Green)
• Identical termination style (PC Pin)

Environmental & Operational Compatibility:

• Identical operating temperature range (-20°C to 70°C)
• Identical mechanical life (200,000 Cycles)
• Identical electrical life (10,000 Cycles)
• Identical sealing features (Process Sealed)
• Identical moisture sensitivity level (MSL 1)

The primary distinction between these parts is product status: UB16SKW03F is obsolete while UB16SKW03N-F is active, and packaging format (tape/reel versus bulk).

Parameter Comparison

Engineering Selection Recommendations

The UB16SKW03N-F is the direct substitute for the obsolete UB16SKW03F. All electrical, mechanical, and environmental parameters are identical. The UB16SKW03N-F carries active product status and ROHS3 compliance certification, making it the appropriate selection for new designs and replacement applications.

For applications requiring the UB16SKW03F, transition to UB16SKW03N-F without modification to circuit design or PCB layout. Both parts share identical pin configuration, mounting footprint, and operational characteristics.

Frequently Asked Questions (FAQ)

Q: Can UB16SKW03N-F directly replace UB16SKW03F in existing designs?

A: Yes. All electrical ratings, mechanical dimensions, and operational parameters are identical. No circuit or layout modifications are required.

Q: What is the difference between UB16SKW03F and UB16SKW03N-F?

A: The primary differences are product status (obsolete versus active) and packaging format. The UB16SKW03N-F is ROHS3 compliant. All functional specifications are identical.

Q: Are there packaging differences between these parts?

A: UB16SKW03F is supplied in tape/reel packaging, while UB16SKW03N-F is supplied in bulk packaging. This affects procurement and handling but does not impact electrical or mechanical performance.

Q: What are the critical parameters for substitution?

A: Circuit configuration (SPDT), current rating (5A), voltage ratings (125V AC / 30V DC), mounting type (Through Hole), actuator type (Square Button), and termination style (PC Pin) must remain constant for functional equivalence.

Q: Is UB16SKW03N-F suitable for new product designs?

A: Yes. UB16SKW03N-F is the active product with current manufacturer support and ROHS3 compliance, making it the appropriate choice for new designs.
