TAP685M050SCS Equivalent & Substitute Parts

Part Overview

The TAP685M050SCS is a 6.8 µF conformal coated tantalum capacitor rated for 50 V operation in a radial through-hole package. This component is manufactured by KYOCERA AVX and maintains Active product status with full RoHS3 compliance. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, design optimization, or application-specific tolerance requirements.

Substitute Part Grouping Explanation

Substitution of the TAP685M050SCS is permissible when the following criteria are maintained:

• Capacitance value remains 6.8 µF
• Voltage rating remains 50 V or higher
• ESR remains 2 Ohm
• Operating temperature range remains -55°C to 125°C
• Package type remains radial through-hole with identical lead spacing (0.098")
• Physical dimensions remain within the specified envelope
• Conformal coating is maintained
• RoHS3 compliance is maintained

The TAP685K050SCS qualifies as a direct substitute based on these criteria. The primary distinction is tolerance specification: the substitute offers ±10% tolerance compared to the main part's ±20% tolerance, representing an upgrade in capacitance accuracy while maintaining all other electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the TAP685M050SCS and TAP685K050SCS maintain Active product status and full ROHS3 compliance. Selection between these parts is determined by tolerance requirements:

• Use TAP685M050SCS when ±20% capacitance tolerance is acceptable for the application.
• Use TAP685K050SCS when tighter ±10% capacitance tolerance is required for improved circuit performance or when inventory availability favors this variant.

Both parts are electrically and mechanically interchangeable within their respective tolerance specifications. No design modifications are required for substitution.

Frequently Asked Questions (FAQ)

Q: Can TAP685K050SCS replace TAP685M050SCS in existing designs?

A: Yes. Both parts share identical electrical ratings (6.8 µF, 50 V, 2 Ohm ESR), operating temperature range, and physical dimensions. The substitute offers improved tolerance (±10% vs ±20%), making it a direct replacement without circuit modifications.

Q: What is the primary difference between these two parts?

A: The tolerance specification differs. TAP685M050SCS carries ±20% tolerance, while TAP685K050SCS carries ±10% tolerance. All other parameters—capacitance, voltage, ESR, temperature range, and package dimensions—are identical.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the same radial through-hole package with 0.276" diameter (7.00mm), 0.413" maximum seated height (10.50mm), and 0.098" lead spacing (2.50mm). PCB layout modifications are not required.

Q: Do both parts meet RoHS requirements?

A: Yes. Both TAP685M050SCS and TAP685K050SCS are ROHS3 compliant and REACH unaffected.

Q: What is the ESR specification, and is it identical between parts?

A: Both parts specify 2 Ohm ESR. This parameter is critical for high-frequency filtering and transient response applications and remains constant across both variants.
