F380J106MMAAH2 Equivalent & Substitute Parts

Part Overview

The F380J106MMAAH2 is a 10 µF molded tantalum polymer capacitor rated at 6.3 V in 0603 (1608 Metric) surface mount package. This component is classified as Not For New Designs, indicating it has been superseded in the manufacturer's product line. Finding equivalent substitute parts is necessary for ongoing production support, maintenance applications, and legacy system repairs where this specific part number may no longer be readily available or where design flexibility permits component substitution.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the F380J106MMAAH2 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 10 µF (exact match required)
• Package / Case: 0603 (1608 Metric) (exact match required for PCB compatibility)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -55°C ~ 105°C (minimum requirement)
• Tolerance: ±20% (acceptable range)

Allowable Variation Parameters:

• Voltage - Rated: May be equal to or greater than 6.3 V (higher voltage rating provides design margin)
• ESR @ 100kHz: May be equal to or slightly higher than 200 mOhm (within acceptable performance limits for general purpose applications)
• Lifetime @ Temp.: Not a substitution-limiting factor if other parameters align
• Packaging Format: Cut Tape (CT) and Tape & Reel (TR) are both acceptable for procurement

The TCSOM1A106M8R-ZM1 from Rohm Semiconductor qualifies as a direct substitute based on these criteria.

Parameter Comparison

Engineering Selection Recommendations

The TCSOM1A106M8R-ZM1 is a qualified substitute for the F380J106MMAAH2 based on the following engineering criteria:

Compliance & Certification Alignment: Both components maintain ROHS3 compliance and identical MSL ratings (3, 168 Hours), ensuring compatibility with current manufacturing and storage requirements.

Product Status Advantage: The substitute part carries Active product status, whereas the original is designated Not For New Designs. This distinction is significant for long-term supply chain stability and technical support availability.

Electrical Performance: The substitute's higher voltage rating (10 V versus 6.3 V) provides additional design margin without compromising circuit functionality in applications originally specified for 6.3 V operation. The increased ESR (300 mOhm versus 200 mOhm) remains within acceptable limits for general purpose capacitor applications and does not introduce performance degradation in typical filtering and energy storage circuits.

Physical Compatibility: Both components share identical footprint dimensions (0603 / 1608 Metric) and mounting type. The substitute's maximum seated height of 0.039" (1.00mm) versus the original's 0.035" (0.90mm) represents a 0.10mm increase. This minor dimensional difference requires verification against PCB layout constraints and component clearance requirements in the specific application.

Frequently Asked Questions (FAQ)

Q: Can the TCSOM1A106M8R-ZM1 be used as a direct replacement for the F380J106MMAAH2 on existing PCBs?

A: Yes, the TCSOM1A106M8R-ZM1 is electrically and mechanically compatible for PCB replacement. Both components use the 0603 (1608 Metric) package with identical footprint dimensions. The substitute's maximum seated height of 1.00mm is 0.10mm taller than the original; verify this does not conflict with component placement or enclosure clearance in your specific assembly.

Q: Why is the substitute part rated at 10 V instead of 6.3 V?

A: Higher voltage ratings provide design margin and do not negatively impact circuit performance in applications originally specified for lower voltages. A 10 V rated capacitor operating at 6.3 V experiences reduced electrical stress and typically exhibits improved reliability characteristics.

Q: What is the significance of the "Not For New Designs" status on the original part?

A: This designation indicates the F380J106MMAAH2 has been superseded in the manufacturer's product line. While existing inventory may be available, the manufacturer does not recommend this part for new circuit designs. The substitute's Active status ensures ongoing availability and manufacturer technical support.

Q: Are there any performance differences in ESR between these two parts?

A: The substitute exhibits 300 mOhm ESR at 100kHz compared to the original's 200 mOhm. This 100 mOhm increase is within acceptable tolerances for general purpose tantalum polymer capacitor applications and does not introduce measurable performance degradation in typical filtering, decoupling, or energy storage circuits.

Q: Do both parts meet the same compliance and environmental standards?

A: Yes. Both the F380J106MMAAH2 and TCSOM1A106M8R-ZM1 are ROHS3 compliant, carry identical MSL ratings (3, 168 Hours), and operate across the same temperature range (-55°C ~ 105°C). They meet equivalent environmental and regulatory requirements for manufacturing and deployment.

Q: What packaging formats are available for the substitute part?

A: The TCSOM1A106M8R-ZM1 is supplied in Tape & Reel (TR) format. The original F380J106MMAAH2 is available in both Cut Tape (CT) and Digi-Reel® formats. Verify your procurement and assembly process requirements when selecting packaging format.
