F970J106MBA Equivalent & Substitute Parts

Part Overview

The F970J106MBA is a 10 µF molded tantalum capacitor manufactured by KYOCERA AVX, rated for 6.3 V operation in a 1411 (3528 Metric) surface mount package. This component is classified as Active product status and is designed for applications requiring reliable energy storage in compact form factors. Substitute parts are identified when equivalent electrical and mechanical specifications can be met by alternative manufacturers while maintaining functional compatibility within the same package envelope and electrical rating parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the F970J106MBA is determined by strict equivalence across the following parameters:

• Capacitance value: 10 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage rating: 6.3 V (exact match required)
• Package / Case: 1411 (3528 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match or wider range acceptable)
• RoHS Compliance: ROHS3 Compliant (compliance status must be maintained)

The substitute part T491B106M006AT meets all mandatory electrical and mechanical parameters. Variations in ESR (Equivalent Series Resistance), MSL (Moisture Sensitivity Level), and physical height do not disqualify substitution when all primary parameters align.

Parameter Comparison

Engineering Selection Recommendations

Both the F970J106MBA and T491B106M006AT are Active product status components with ROHS3 compliance and REACH Unaffected status. Selection between these parts should be based on:

• Circuit performance requirements related to ESR: The F970J106MBA exhibits lower ESR (2.1 Ohm) compared to the T491B106M006AT (4.6 Ohm). Applications sensitive to impedance characteristics should account for this 1.4 Ohm difference.
• Moisture handling requirements: The T491B106M006AT provides superior moisture resistance with MSL 1 (Unlimited) versus MSL 3 (168 Hours) for the F970J106MBA. High-humidity or extended storage environments favor the KEMET substitute.
• Physical height constraints: The T491B106M006AT seated height is 0.083" (2.10mm) versus 0.091" (2.30mm) for the KYOCERA AVX part. Space-constrained PCB layouts may benefit from the lower profile substitute.
• Availability and supply chain: Both parts are Active status with documented inventory. Selection may be driven by procurement lead times and supplier availability.

Frequently Asked Questions (FAQ)

Q: Can T491B106M006AT replace F970J106MBA in any application?

A: Direct substitution is valid when circuit design does not impose strict ESR requirements below 4.6 Ohm. The electrical ratings (10 µF, ±20%, 6.3 V) and package dimensions (1411 / 3528 Metric) are identical. Verify ESR tolerance in high-frequency or low-impedance applications before substitution.

Q: What is the significance of the different MSL ratings?

A: MSL 3 (168 Hours) for the F970J106MBA indicates moisture absorption limits during storage and handling. MSL 1 (Unlimited) for the T491B106M006AT provides greater flexibility in warehouse conditions and extended shelf life without bake-out procedures. For standard manufacturing environments, both are acceptable.

Q: Are the physical dimensions truly equivalent?

A: Footprint dimensions are identical (0.138" L x 0.110" W / 4.60mm x 2.80mm). The seated height differs by 0.008" (0.20mm), with the KEMET part being lower profile. This difference is negligible for most applications but may be critical in space-constrained designs.

Q: Do both parts meet automotive and high-reliability standards?

A: The F970J106MBA carries AEC-Q200 rating with Automotive and High Reliability features. The T491B106M006AT is classified as General Purpose. Applications requiring automotive qualification should verify compliance requirements before substitution.

Q: What packaging formats are available for each part?

A: F970J106MBA is supplied in Tape & Reel (TR) format. T491B106M006AT is available in Cut Tape (CT) & Digi-Reel® format. Procurement and assembly processes should account for these packaging differences.
