TAJS685K010RNJ Equivalent & Substitute Parts

Part Overview

The TAJS685K010RNJ is a 6.8 µF molded tantalum capacitor manufactured by KYOCERA AVX, rated for 10 V operation in a 1206 (3216 Metric) surface mount package. This component is classified as Active product status and is ROHS3 compliant. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same capacitance, voltage rating, tolerance, and package footprint.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence in the following parameters: capacitance (6.8 µF), voltage rating (10 V), tolerance (±10%), package footprint (1206 / 3216 Metric), mounting type (Surface Mount), and compliance certifications (ROHS3, REACH Unaffected). All identified substitute parts maintain these core electrical and mechanical specifications. Variations in ESR (Equivalent Series Resistance), height-seated maximum, and packaging format (Tape & Reel vs. Cut Tape) do not disqualify substitution when the primary functional parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and ROHS3 compliance. Selection between TAJS685K010RNJ and its equivalents should be based on packaging format availability, inventory requirements, and PCB layout constraints related to component height. TAJA685K010RNJ offers the highest inventory availability (2400 Pcs) with identical electrical specifications but differs in packaging format and seated height. TPSA685K010R1800 provides lower ESR (1.8 Ohm) compared to the main part (4 Ohm), which may be advantageous in applications requiring reduced impedance. The Vishay Sprague 293D685X9010A2TE3 and KEMET T491A685K010AT provide cross-manufacturer alternatives with equivalent electrical performance and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can TAJA685K010RNJ be used as a direct replacement for TAJS685K010RNJ? A: Yes. Both parts are manufactured by KYOCERA AVX with identical capacitance (6.8 µF), voltage rating (10 V), tolerance (±10%), package footprint (1206), and ESR (4 Ohm). The primary difference is packaging format (Cut Tape vs. Tape & Reel) and seated height (1.80mm vs. 1.20mm). Verify PCB layout clearance for the increased height before substitution.

Q: What is the significance of ESR variation among substitute parts? A: ESR (Equivalent Series Resistance) affects impedance characteristics and ripple current handling. TPSA685K010R1800 features 1.8 Ohm ESR compared to 4 Ohm in TAJS685K010RNJ and TAJA685K010RNJ. Lower ESR may improve performance in high-frequency or high-ripple-current applications but does not affect basic capacitance or voltage rating equivalence.

Q: Are cross-manufacturer substitutes (Vishay Sprague, KEMET) fully compatible? A: Yes, for electrical function. 293D685X9010A2TE3 (Vishay Sprague) and T491A685K010AT (KEMET) maintain identical capacitance, voltage, tolerance, package, and compliance specifications. Verify manufacturer datasheets for any application-specific performance characteristics before final selection.

Q: Does packaging format affect electrical performance? A: No. Tape & Reel (TR) and Cut Tape (CT) formats are handling and delivery methods only. Electrical specifications remain identical. Selection should be based on assembly equipment compatibility and inventory management requirements.

Q: What compliance certifications apply to all substitute parts? A: All parts listed are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component use.
