Substitute Part Grouping Explanation

Substitution eligibility for the TPSB686M010R0600 is determined by the following critical parameters:

Electrical Equivalence Requirements:

• Capacitance: 68 µF (exact match required)
• Voltage Rating: 10 V (exact match required)
• Tolerance: ±20% or tighter (±10% is acceptable as upgrade)
• ESR: 600mOhm or lower (lower ESR is acceptable as upgrade)

Mechanical Compatibility Requirements:

• Package / Case: 1411 (3528 Metric), 1210 (exact match required)
• Physical Dimensions: 0.138" L x 0.110" W / 4.60mm x 2.80mm (exact match required)
• Height - Seated (Max): 0.083" (2.10mm) (exact match required)
• Mounting Type: Surface Mount (exact match required)

Environmental & Compliance Requirements:

• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Two substitute parts meet these criteria: TPSB686K010R0600 (tolerance upgrade) and TAJB686M010RNJ (ESR upgrade).

Parameter Comparison

Engineering Selection Recommendations

TPSB686K010R0600 (Tolerance Upgrade): This substitute offers improved tolerance specification (±10% versus ±20%) while maintaining identical ESR, package, and all environmental parameters. Selection of this part provides tighter capacitance accuracy for applications requiring enhanced performance margins. All compliance certifications (ROHS3, MSL 1) remain equivalent.

TAJB686M010RNJ (ESR Upgrade): This substitute, from the TAJ series, provides significantly lower ESR (1.4Ohm versus 600mOhm) while maintaining the original ±20% tolerance and all package specifications. Lower ESR reduces impedance and heat generation in high-frequency or high-ripple-current applications. All compliance certifications (ROHS3, MSL 1) remain equivalent. This part is manufacturer-recommended for applications benefiting from improved ESR performance.

Both substitutes maintain active product status and full regulatory compliance with the original specification.

Frequently Asked Questions (FAQ)

Q: Can TPSB686K010R0600 be used as a direct replacement for TPSB686M010R0600?

A: Yes. TPSB686K010R0600 is electrically and mechanically compatible. The ±10% tolerance is tighter than the original ±20%, making it suitable for direct substitution. ESR, package dimensions, voltage rating, and all environmental specifications are identical.

Q: What is the primary difference between TPSB686M010R0600 and TAJB686M010RNJ?

A: The primary difference is ESR: TAJB686M010RNJ has 1.4Ohm ESR compared to 600mOhm in the original part. Both maintain 68 µF capacitance, 10 V rating, ±20% tolerance, and identical package specifications. Lower ESR in the TAJ series reduces impedance in high-frequency applications.

Q: Are all three parts in the same physical package?

A: Yes. All three parts use the 1411 (3528 Metric) package with identical dimensions (0.138" L x 0.110" W / 4.60mm x 2.80mm) and maximum seated height (0.083" / 2.10mm), ensuring PCB layout compatibility.

Q: Do substitute parts maintain the same compliance certifications?

A: Yes. Both TPSB686K010R0600 and TAJB686M010RNJ are ROHS3 Compliant with MSL 1 (Unlimited) rating, matching the original part's environmental and regulatory status.

Q: Which substitute should be selected for high-ripple-current applications?

A: TAJB686M010RNJ is the appropriate selection for high-ripple-current applications due to its significantly lower ESR (1.4Ohm), which reduces impedance and heat dissipation compared to the 600mOhm ESR of the original part.
