Substitute Part Grouping Explanation

Substitution of the F970J156MBA is permissible with the F970J156KBA based on the following criteria:

Identical Parameters:

• Capacitance: 15 µF (exact match)
• Voltage Rating: 6.3 V (exact match)
• Type: Molded Tantalum (exact match)
• ESR: 2 Ohm (exact match)
• Package / Case: 1411 (3528 Metric) (exact match)
• Mounting Type: Surface Mount (exact match)
• Operating Temperature Range: -55°C ~ 125°C (exact match)
• AEC-Q200 Certification (exact match)
• ROHS3 Compliance (exact match)
• MSL Rating: 3 (168 Hours) (exact match)

Allowable Variation:

• Tolerance: F970J156MBA specifies ±20%; F970J156KBA specifies ±10%. The substitute part exhibits tighter tolerance, which is acceptable for applications where the original ±20% tolerance is specified, as ±10% tolerance remains within the acceptable operating window.

Parameter Comparison

Engineering Selection Recommendations

The F970J156KBA is a direct substitute for the F970J156MBA in applications where the original part is unavailable. Both parts maintain identical electrical and mechanical specifications with the exception of capacitance tolerance. The substitute part's ±10% tolerance is superior to the original ±20% specification and does not introduce any compatibility issues. Both parts carry AEC-Q200 automotive qualification and ROHS3 compliance, ensuring suitability for high-reliability applications. The identical package footprint, thermal operating range, and ESR characteristics ensure drop-in compatibility without circuit redesign or PCB layout modification.

Frequently Asked Questions (FAQ)

Q: Can F970J156KBA be used as a direct replacement for F970J156MBA?

A: Yes. The F970J156KBA is a direct substitute. All electrical parameters, package dimensions, and certifications are identical. The only difference is the capacitance tolerance specification, where the substitute part offers ±10% versus the original ±20%, which is acceptable for all applications designed for the original part.

Q: Are there any PCB layout or footprint changes required when substituting F970J156KBA for F970J156MBA?

A: No. Both parts use the identical 1411 (3528 Metric) package with matching dimensions of 0.138" L x 0.110" W and maximum seated height of 0.091". No PCB layout modifications are necessary.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both F970J156MBA and F970J156KBA carry AEC-Q200 certification and are suitable for automotive and high-reliability applications.

Q: What is the significance of the tolerance difference between these parts?

A: The F970J156MBA specifies ±20% tolerance, while F970J156KBA specifies ±10% tolerance. The substitute part's tighter tolerance means capacitance values will be closer to the nominal 15 µF specification. This is advantageous and does not create compatibility issues for circuits designed with the original ±20% tolerance part.

Q: Are moisture sensitivity levels identical?

A: Yes. Both parts are rated MSL 3 (168 Hours), indicating identical moisture handling and storage requirements.
