Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TAP684M035SLZ is determined by strict equivalence in the following critical parameters:

• Capacitance Value: 0.68 µF (exact match required)
• Voltage Rating: 35 V (exact match required)
• Type: Conformal Coated Tantalum (exact match required)
• ESR: 10 Ohm (exact match required)
• Mounting Type: Through Hole Radial (exact match required)
• Physical Dimensions: 0.177" Dia (4.50 mm), Height 0.276" (7.00 mm), Lead Spacing 0.098" (2.50 mm) (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Compliance: ROHS3 Compliant (exact match required)

The TAP684K035SCS qualifies as a direct substitute based on identical electrical and mechanical specifications. The tolerance specification differs (±10% versus ±20%), representing an upgrade in capacitance accuracy while maintaining all other critical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the TAP684M035SLZ and TAP684K035SCS are active production components manufactured by KYOCERA AVX with identical compliance certifications (ROHS3 Compliant, REACH Unaffected). Selection between these parts is based on tolerance requirements and inventory availability.

The TAP684M035SLZ provides ±20% capacitance tolerance and is suitable for applications where this tolerance band is acceptable. The TAP684K035SCS offers improved accuracy with ±10% tolerance while maintaining all other electrical and mechanical specifications. Both parts meet the same operating temperature range, lifetime specifications, and physical form factor requirements for direct board-level substitution.

Frequently Asked Questions (FAQ)

Q: Can TAP684K035SCS replace TAP684M035SLZ in existing designs?

A: Yes. The TAP684K035SCS is a direct substitute with identical electrical ratings, physical dimensions, and mounting characteristics. The difference is improved capacitance tolerance (±10% versus ±20%), which represents an upgrade in accuracy.

Q: Are there any physical compatibility issues between these parts?

A: No. Both parts share identical package specifications: 0.177" diameter (4.50 mm), 0.276" maximum seated height (7.00 mm), and 0.098" lead spacing (2.50 mm). They are mechanically interchangeable in radial through-hole applications.

Q: What is the significance of the tolerance difference?

A: The TAP684M035SLZ allows capacitance values between 0.544 µF and 0.816 µF (±20% of 0.68 µF). The TAP684K035SCS restricts this to 0.612 µF to 0.748 µF (±10% of 0.68 µF). Applications requiring tighter capacitance control benefit from the substitute part.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both parts are ROHS3 Compliant and REACH Unaffected, meeting identical environmental and regulatory standards.

Q: Is there a difference in reliability or lifetime between these parts?

A: No. Both parts specify 1000 hours lifetime at 85°C and operate across the same temperature range (-55°C to 125°C).
