Substitute Part Grouping Explanation

Substitution for the T86D685K035ESSL is determined by strict equivalence across the following parameters: capacitance value (6.8 µF), voltage rating (35 V), tolerance (±10%), package type (2917/7343 Metric), mounting configuration (surface mount), and operating temperature range (-55°C ~ 125°C). The identified substitute parts maintain these core electrical and mechanical specifications, ensuring functional compatibility in the target application.

The two substitute parts are grouped as follows:

Direct Substitute (Active Status): TAWD685K035R0600 from KYOCERA AVX maintains all critical parameters with an ESR specification of 600mOhm, representing a minor increase from the original 500mOhm specification. This part is currently in active production status.

Manufacturer-Recommended Substitute (Active Status): TBJD685K035LBSB0024 from KYOCERA AVX meets all core electrical and mechanical requirements. ESR specification is not provided for this variant. This part is also in active production status.

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Active Production: TAWD685K035R0600 is the preferred substitute. This part is in active production status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. The ESR specification of 600mOhm represents a 20% increase from the original 500mOhm; applications with strict ESR requirements should evaluate circuit performance impact.

For Legacy System Support: TBJD685K035LBSB0024 is available as an alternative when TAWD685K035R0600 is unavailable. This part maintains active production status and meets all core electrical and mechanical specifications. ESR is not specified for this variant; contact the manufacturer for detailed ESR data if circuit performance is ESR-dependent.

Compliance Considerations: TAWD685K035R0600 offers ROHS3 compliance, suitable for applications with regulatory requirements. Both TBJD685K035LBSB0024 and the original T86D685K035ESSL are RoHS non-compliant; applications requiring RoHS compliance should prioritize TAWD685K035R0600.

Frequently Asked Questions (FAQ)

Q: Can TAWD685K035R0600 be used as a direct replacement for T86D685K035ESSL?

A: Yes. Both parts share identical capacitance (6.8 µF), voltage rating (35 V), tolerance (±10%), package type (2917/7343 Metric), and operating temperature range (-55°C ~ 125°C). The ESR difference (600mOhm vs. 500mOhm) must be evaluated for applications where ESR is a critical performance parameter.

Q: What is the difference between TAWD685K035R0600 and TBJD685K035LBSB0024?

A: Both parts meet core electrical and mechanical specifications. TAWD685K035R0600 specifies 600mOhm ESR and carries ROHS3 compliance. TBJD685K035LBSB0024 does not specify ESR and is RoHS non-compliant. TAWD685K035R0600 is recommended for new designs requiring regulatory compliance.

Q: Are the physical dimensions identical across all three parts?

A: Yes. All three parts use the 2917 (7343 Metric) package with identical dimensions: 0.287" L x 0.169" W (7.30mm x 4.30mm) and maximum seated height of 0.122" (3.10mm). PCB layout and assembly tooling are interchangeable.

Q: Why is the original T86D685K035ESSL obsolete?

A: The part is listed as obsolete by the manufacturer. Substitute parts from KYOCERA AVX are in active production and provide equivalent functionality with improved compliance status.

Q: Does ESR affect circuit performance?

A: ESR impacts ripple current handling, transient response, and thermal characteristics. The 20% ESR increase in TAWD685K035R0600 (600mOhm vs. 500mOhm) should be evaluated in applications with high ripple current or stringent transient response requirements.

Q: What is the Moisture Sensitivity Level (MSL) rating?

A: All three parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
