Substitute Part Grouping Explanation

Substitution for the T86D685K035EASL is determined by strict equivalence across the following parameters:

• Capacitance: 6.8 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating: 35 V (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• Moisture Sensitivity Level: 1 (exact match required)

The identified substitutes meet all core electrical and mechanical parameters. Variations in ESR and product status are noted but do not preclude functional equivalence within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

Both TAWD685K035R0600 and TBJD685K035LBSB0024 satisfy the core electrical and mechanical equivalence criteria for the obsolete T86D685K035EASL.

TAWD685K035R0600 is an active product with ROHS3 compliance, making it suitable for applications requiring current regulatory alignment. The ESR specification of 600mOhm represents a 20% increase over the original part; this variance remains within acceptable limits for most circuit applications but should be evaluated against specific ripple current and thermal performance requirements.

TBJD685K035LBSB0024 is an active product designated as manufacturer-recommended by KYOCERA AVX. RoHS compliance status matches the original part. ESR is not specified for this variant.

Selection between these substitutes depends on regulatory requirements, packaging preference (Tape & Reel versus Bulk), and ESR tolerance in the target application.

Frequently Asked Questions (FAQ)

Q: Can TAWD685K035R0600 and TBJD685K035LBSB0024 be used interchangeably with T86D685K035EASL?

A: Both parts meet the specified electrical and mechanical parameters: 6.8 µF capacitance, ±10% tolerance, 35 V rating, 2917 package, and -55°C to 125°C operating range. Functional equivalence is established within these parameters. ESR differences should be evaluated for specific circuit requirements.

Q: What is the significance of the ESR difference between T86D685K035EASL (500mOhm) and TAWD685K035R0600 (600mOhm)?

A: ESR affects ripple current handling and thermal performance. The 20% increase in ESR for TAWD685K035R0600 may impact high-frequency or high-current applications. Circuit simulation or thermal analysis is appropriate for applications with stringent ripple current specifications.

Q: Why is TBJD685K035LBSB0024 listed without ESR specification?

A: ESR data was not provided in the component documentation. Contact the manufacturer for ESR specifications if this parameter is critical to your application.

Q: Does RoHS compliance affect substitution eligibility?

A: RoHS compliance is a regulatory and supply chain consideration, not an electrical equivalence criterion. TAWD685K035R0600 offers ROHS3 compliance for applications requiring this certification. TBJD685K035LBSB0024 matches the original RoHS status.

Q: What packaging options are available?

A: TAWD685K035R0600 is supplied in Tape & Reel format. TBJD685K035LBSB0024 is supplied in Bulk format. Both are surface mount compatible with the 2917 package footprint.
