Substitute Part Grouping Explanation

Substitution for the TAP686M016SCS is determined by strict equivalence in the following parameters:

• Capacitance value: 68 µF (exact match required)
• Voltage rating: 16 V (exact match required)
• Type: Conformal coated tantalum (exact match required)
• Mounting configuration: Through hole radial (exact match required)
• Physical dimensions: 0.354" diameter, 0.492" maximum height, 0.098" lead spacing (exact match required)
• ESR: 1 Ohm (exact match required)
• Operating temperature range: -55°C to 125°C (exact match required)

The TAP686K016SCS qualifies as a direct substitute based on these parameters. The primary difference is tolerance specification: the substitute offers ±10% tolerance compared to the main part's ±20% tolerance, representing an upgrade in precision without affecting electrical or mechanical compatibility.

Engineering Selection Recommendations

Both the TAP686M016SCS and TAP686K016SCS maintain active product status and full ROHS3 compliance. Selection between these parts should be based on tolerance requirements for your specific application. The TAP686K016SCS provides tighter tolerance control (±10%) and may be preferred in circuits where capacitance precision directly impacts performance. Both components are suitable for applications requiring conformal coating protection and operate across the full military temperature range of -55°C to 125°C.

Frequently Asked Questions (FAQ)

Q: Can TAP686K016SCS replace TAP686M016SCS in my circuit?

A: Yes. Both parts are electrically and mechanically identical except for tolerance specification. The substitute offers improved tolerance (±10% versus ±20%) without any compatibility issues.

Q: Are the physical dimensions identical?

A: Yes. Both parts share identical radial package dimensions: 0.354" diameter, 0.492" maximum seated height, and 0.098" lead spacing. They are mechanically interchangeable on PCBs designed for either part.

Q: Do both parts meet the same compliance standards?

A: Yes. Both TAP686M016SCS and TAP686K016SCS are ROHS3 compliant and REACH unaffected, meeting equivalent environmental and regulatory requirements.

Q: What is the significance of the tolerance difference?

A: The TAP686K016SCS tolerance of ±10% provides tighter capacitance accuracy compared to the ±20% tolerance of the TAP686M016SCS. Applications requiring precise capacitance values benefit from the substitute part's improved tolerance specification.

Q: Are both parts available in the same packaging format?

A: Yes. Both components are supplied in bulk packaging as through-hole radial tantalum capacitors with identical lead configurations.
