Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TAP685M025SRW is determined by the following critical parameters:

• Capacitance Value: Must be 6.8 µF (no deviation)
• Voltage Rating: Must be 25 V or higher
• Mounting Type: Must be Through Hole Radial
• Physical Dimensions: Must match 0.197" Dia (5.00mm) and 0.354" (9.00mm) height
• Lead Spacing: Must be 0.098" (2.50mm)
• Type: Must be Conformal Coated Tantalum
• Operating Temperature Range: Must support -55°C to 125°C
• Compliance: Must maintain ROHS3 compliance

The TAP685K025SCS qualifies as a direct substitute based on identical capacitance, voltage rating, physical dimensions, lead spacing, temperature range, and compliance certifications. The primary difference is tolerance specification (±10% versus ±20%) and packaging format (Bulk versus Tape & Reel).

Parameter Comparison

Engineering Selection Recommendations

The TAP685K025SCS is a valid substitute for the TAP685M025SRW based on electrical and mechanical compatibility. Both components are manufactured by KYOCERA AVX, maintain Active product status, and satisfy ROHS3 compliance requirements. The substitute offers improved tolerance specification (±10% versus ±20%), which may provide enhanced precision in applications requiring tighter capacitance control. Packaging format differs (Bulk versus Tape & Reel), which may affect procurement and assembly workflows but does not impact electrical performance or physical fit. Both components support identical operating temperature ranges and maintain equivalent series resistance specifications.

Frequently Asked Questions (FAQ)

Q: Can TAP685K025SCS replace TAP685M025SRW in existing designs?

A: Yes. Both components share identical capacitance (6.8 µF), voltage rating (25 V), physical dimensions, lead spacing, and operating temperature range. The substitute is electrically and mechanically compatible for direct board-level replacement.

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

A: Tolerance defines the acceptable deviation from the nominal capacitance value. TAP685M025SRW allows ±20% deviation (5.44 µF to 8.16 µF), while TAP685K025SCS allows ±10% deviation (6.12 µF to 7.48 µF). Applications requiring tighter capacitance control should specify the ±10% variant.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel (TR) and Bulk packaging formats contain identical components. Packaging differences affect only procurement, storage, and automated assembly compatibility, not electrical characteristics or reliability.

Q: Are both parts RoHS compliant?

A: Yes. Both TAP685M025SRW and TAP685K025SCS are ROHS3 compliant and suitable for applications requiring regulatory compliance with hazardous substance restrictions.

Q: Can these parts be used interchangeably in high-reliability applications?

A: Both components are rated for identical operating temperature ranges (-55°C to 125°C) and lifetime specifications (1000 Hrs @ 85°C). Selection between them should be based on tolerance requirements and packaging availability rather than reliability considerations.
