Key Parameters

Substitute Part Grouping Explanation

Substitution of the T598B686M006ATE0707280 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 68 µF (exact match required)
• Voltage rating: 6.3 V (exact match required)
• ESR specification: 70 mOhm @ 100kHz (exact match required)
• Tolerance: ±20% (exact match required)

Mechanical Parameters:

• Package format: 1411 (3528 Metric) (exact match required)
• Mounting type: Surface Mount (exact match required)
• Physical dimensions: 0.138" L × 0.110" W × 0.083" H maximum (exact match required)

Compliance & Qualification:

• Series: KO-CAP® T598 (same manufacturer series)
• AEC-Q200 automotive qualification (maintained)
• RoHS3 compliance (maintained)
• MSL rating: 3 (168 Hours) (maintained)

The substitute part T598B686M006ATE070 meets all these criteria and is therefore classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the T598B686M006ATE0707280 and T598B686M006ATE070 are active production parts from KEMET's KO-CAP® T598 series with identical electrical, mechanical, and compliance specifications. Selection between these parts should be based on:

Availability & Inventory: The T598B686M006ATE070 variant currently maintains higher inventory levels (8771 pieces) compared to the T598B686M006ATE0707280 (864 pieces), making it the preferred choice for high-volume procurement or extended lead-time mitigation.

Compliance Assurance: Both parts maintain AEC-Q200 automotive qualification, ROHS3 compliance, and identical MSL ratings, ensuring suitability for automotive and industrial applications without additional qualification requirements.

Design Continuity: Direct substitution is permissible without circuit redesign, PCB layout modification, or thermal management recalculation, as all critical parameters remain constant.

Frequently Asked Questions (FAQ)

Q: Can T598B686M006ATE070 be used as a direct replacement for T598B686M006ATE0707280 in existing designs?

A: Yes. Both parts are parametric equivalents with identical capacitance (68 µF), voltage rating (6.3 V), ESR (70 mOhm @ 100kHz), package format (1411/3528 Metric), and compliance certifications. Direct substitution requires no design changes.

Q: Are there any differences in the part numbers that affect compatibility?

A: The part numbers differ only in their trailing suffix designations (0707280 versus 070). These suffixes represent internal KEMET manufacturing or packaging batch identifiers and do not affect electrical performance, mechanical fit, or functional characteristics.

Q: What are the critical parameters that must match for substitution?

A: Capacitance value, voltage rating, ESR specification, package format, and mounting type must be identical. Additionally, compliance ratings (AEC-Q200, RoHS3) and MSL classification must be maintained for automotive and moisture-sensitive applications.

Q: Can these parts be used interchangeably in high-frequency or high-temperature applications?

A: Yes. Both parts share identical operating temperature ranges (-55°C to 125°C), lifetime specifications (2000 hours @ 125°C), and ESR characteristics (70 mOhm @ 100kHz), making them suitable for equivalent performance in demanding thermal and frequency environments.

Q: Is there any risk in switching between these two part numbers during production?

A: No additional risk exists beyond standard component procurement practices. Both parts are active production items from the same manufacturer series with identical specifications and certifications. Standard incoming inspection and testing protocols apply equally to both variants.
