Key Parameters

Substitute Part Grouping Explanation

Substitution of the ESRE151M06R is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Capacitance value of 150 µF (no deviation)
• Voltage rating of 6.3 V (substitute must equal or exceed)
• Tolerance of ±20% (substitute must equal or be tighter)
• Package / Case designation of 2917 (7343 Metric) (physical footprint must be identical)
• Surface mount mounting type (assembly compatibility)
• Polymer capacitor type (electrical behavior consistency)

Performance Parameters:

• ESR must be within acceptable range for the application (12 mOhm baseline)
• Operating temperature range must cover the circuit's thermal requirements
• Ripple current rating must support the application's AC current demands
• RoHS3 compliance required for regulatory alignment

The KEMET A700X157M006ATE015 meets all critical matching parameters and is therefore classified as a direct equivalent substitute for the obsolete ESRE151M06R.

Parameter Comparison

Engineering Selection Recommendations

The KEMET A700X157M006ATE015 is a direct equivalent substitute for the obsolete Cornell Dubilier Electronics ESRE151M06R based on the following engineering criteria:

Electrical Equivalence: All critical electrical parameters match exactly: 150 µF capacitance, 6.3 V voltage rating, and ±20% tolerance. The ESR difference of 3 mOhm (12 mOhm vs. 15 mOhm) is within acceptable engineering tolerance for bypass and decoupling applications. The KEMET substitute provides superior ripple current capability (3.9 A vs. 3.3 A at 100 kHz), offering improved performance margin.

Physical Compatibility: Both components use the identical 2917 (7343 Metric) surface mount package with matching land pattern dimensions of 0.287" L x 0.169" W (7.30mm x 4.30mm). The seated height difference of 0.20mm (4.10mm vs. 4.30mm) is negligible for standard PCB assembly and does not affect board-level clearance in typical applications.

Regulatory and Compliance Status: Both components are ROHS3 compliant and carry identical Moisture Sensitivity Level (MSL) ratings of 3 (168 Hours). The KEMET substitute maintains full regulatory alignment with the original design specification.

Production Status: The KEMET A700X157M006ATE015 is in active production with confirmed inventory availability (2146 pieces in stock), ensuring long-term supply continuity compared to the obsolete ESRE151M06R. The KEMET component is packaged in Tape & Reel (TR) format, suitable for automated assembly processes.

Thermal Performance: The KEMET substitute provides an extended operating temperature range of -55°C ~ 125°C compared to the original -55°C ~ 105°C specification, offering additional thermal margin for demanding applications.

Frequently Asked Questions (FAQ)

Q: Can the KEMET A700X157M006ATE015 be used as a direct replacement for the ESRE151M06R without circuit modification?

A: Yes. The KEMET A700X157M006ATE015 is a direct equivalent substitute. All critical electrical parameters (capacitance, voltage rating, tolerance, and type) match exactly. The component uses the identical 2917 (7343 Metric) surface mount package with matching PCB land patterns. No circuit modifications are required.

Q: What is the significance of the 3 mOhm ESR difference between the two parts?

A: The ESRE151M06R has an ESR of 12 mOhm while the KEMET substitute has 15 mOhm. This 3 mOhm difference (25% increase) is within acceptable engineering tolerance for bypass and decoupling applications. The substitute's higher ripple current rating (3.9 A vs. 3.3 A) compensates for the slightly higher ESR, maintaining or improving overall circuit performance.

Q: Are there any height clearance issues due to the 0.20mm seated height difference?

A: No. The KEMET substitute has a maximum seated height of 0.169" (4.30mm) compared to the original 0.161" (4.10mm). This 0.20mm difference is negligible in standard PCB assembly and does not create clearance conflicts in typical board designs. Both components fit within standard component height envelopes.

Q: Does the KEMET substitute maintain the same moisture sensitivity requirements?

A: Yes. Both components carry identical Moisture Sensitivity Level (MSL) ratings of 3 (168 Hours). Handling, storage, and reflow procedures remain unchanged. No modifications to assembly process controls are required.

Q: Why does the KEMET substitute have a higher operating temperature maximum?

A: The KEMET A700X157M006ATE015 is rated for -55°C ~ 125°C compared to the original -55°C ~ 105°C. This extended upper temperature limit reflects the active production status and improved thermal design of the current KEMET polymer capacitor series. The substitute provides additional thermal margin without affecting compatibility with the original -55°C ~ 105°C design specification.

Q: Is the KEMET substitute available in the same packaging format?

A: The KEMET A700X157M006ATE015 is supplied in Tape & Reel (TR) packaging, which is standard for automated surface mount assembly. The original ESRE151M06R packaging format is not specified in the available data. Tape & Reel format is compatible with standard pick-and-place equipment and is the industry standard for high-volume production.

Q: What is the inventory status of the substitute part?

A: The KEMET A700X157M006ATE015 has confirmed inventory of 2146 pieces in stock as new original components. This ensures immediate availability for design transitions, prototype builds, and production orders. The original ESRE151M06R, being obsolete, has limited remaining inventory (3032 pieces) with no future production planned.

Q: Are both components RoHS3 compliant?

A: Yes. Both the ESRE151M06R and the KEMET A700X157M006ATE015 are ROHS3 compliant. No regulatory or environmental compliance issues arise from the substitution.
