TAP685M016SLZ Equivalent & Substitute Parts

Part Overview

The TAP685M016SLZ is a 6.8 µF conformal coated tantalum capacitor rated at 16 V with radial through-hole mounting. Manufactured by KYOCERA AVX, this component is part of the active TAP series and is designed for general-purpose applications requiring reliable energy storage in compact form factors. Finding equivalent or substitute parts may be necessary due to inventory constraints, design optimization requirements, or specific tolerance specifications for your application.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TAP685M016SLZ is permissible when the following critical parameters remain constant or are improved:

• Capacitance Value: Must remain 6.8 µF (no deviation)
• Voltage Rating: Must remain 16 V or higher
• Type: Must remain conformal coated tantalum
• Mounting Type: Must remain through-hole radial
• Physical Dimensions: Must match or fit within PCB layout constraints (0.197" Dia, 0.335" Max Height, 0.098" Lead Spacing)
• ESR: Must remain 4 Ohm or lower
• Operating Temperature Range: Must support -55°C ~ 125°C minimum
• Compliance: Must maintain ROHS3 compliance

The tolerance specification (±20% vs. ±10%) is the primary differentiator for the identified substitute. A tighter tolerance (±10%) represents an upgrade path and does not compromise compatibility with designs specified for ±20% tolerance.

Parameter Comparison

Engineering Selection Recommendations

Both TAP685M016SLZ and TAP685K016SCS are active products manufactured by KYOCERA AVX and maintain full ROHS3 compliance. The TAP685K016SCS represents a direct substitute with identical electrical and mechanical specifications, with the exception of improved tolerance performance (±10% versus ±20%).

Selection between these parts should be based on tolerance requirements for your specific application. If your circuit design requires tighter capacitance tolerance control, the TAP685K016SCS is the appropriate choice. If ±20% tolerance is acceptable, either part is functionally equivalent. Both parts share identical physical footprints, thermal characteristics, and compliance certifications, ensuring seamless integration into existing PCB designs.

Frequently Asked Questions (FAQ)

Q: Can TAP685K016SCS replace TAP685M016SLZ in my design?

A: Yes. The TAP685K016SCS is a direct substitute with identical capacitance, voltage rating, physical dimensions, and mounting configuration. The primary difference is improved tolerance (±10% vs. ±20%), which does not compromise compatibility.

Q: What is the difference between ±20% and ±10% tolerance?

A: Tolerance specifies the allowable deviation of the actual capacitance value from the nominal 6.8 µF specification. ±20% allows deviation between 5.44 µF and 8.16 µF. ±10% allows deviation between 6.12 µF and 7.48 µF. Tighter tolerance (±10%) provides more precise capacitance control for applications requiring strict value accuracy.

Q: Are the physical dimensions identical?

A: Yes. Both parts share identical radial package dimensions: 0.197" diameter, 0.335" maximum seated height, and 0.098" lead spacing. PCB layout and footprints are interchangeable.

Q: Do both parts meet the same compliance standards?

A: Yes. Both TAP685M016SLZ and TAP685K016SCS are ROHS3 compliant and REACH unaffected, meeting identical environmental and regulatory requirements.

Q: Which part should I select for new designs?

A: For new designs, the TAP685K016SCS is recommended due to its tighter tolerance specification, which provides improved capacitance accuracy without any compromise in cost, availability, or performance characteristics.
