TCFGA1D105M8R Equivalent & Substitute Parts

Part Overview

The TCFGA1D105M8R is a 1 µF molded tantalum capacitor rated at 20 V in a 1206 (3216 Metric) surface mount package, manufactured by Rohm Semiconductor. This component is classified as obsolete, making identification of suitable equivalent parts essential for ongoing design support and production continuity. The part features a fail-safe design with built-in fuse protection and operates across the temperature range of -55°C to 125°C. Due to its obsolete status, active equivalent parts from other manufacturers are available to maintain supply chain reliability.

Substitute Part Grouping Explanation

Substitution of the TCFGA1D105M8R is determined by strict equivalence across the following parameters:

• Capacitance: 1 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage Rating: 20 V (exact match required)
• Package: 1206 (3216 Metric) (exact match required)
• Physical Dimensions: 0.126" L x 0.063" W, Height 0.071" max (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• Mounting Type: Surface Mount (exact match required)
• RoHS3 Compliance: Required
• MSL Rating: 1 (Unlimited) (exact match required)

The identified substitute parts TPSA105M020R3000 and TRJA105M020RRJ from KYOCERA AVX meet all mandatory electrical and mechanical parameters. Both parts are classified as active products, ensuring long-term availability and supply chain stability.

Parameter Comparison

Engineering Selection Recommendations

Both TPSA105M020R3000 and TRJA105M020RRJ are suitable replacements for the obsolete TCFGA1D105M8R based on complete electrical and mechanical parameter equivalence. Selection between the two substitute parts should be based on ESR requirements for the specific application:

TPSA105M020R3000 features an ESR of 3 Ohm and is classified as active with 2509 units in stock, providing superior availability and lower series resistance characteristics.

TRJA105M020RRJ features an ESR of 6.63 Ohm and is classified as active with 1357 units in stock, suitable for applications where higher ESR is acceptable.

Both parts maintain ROHS3 compliance and MSL 1 (Unlimited) rating, ensuring compatibility with modern manufacturing processes and long-term reliability in storage and deployment.

Frequently Asked Questions (FAQ)

Q: Can TPSA105M020R3000 or TRJA105M020RRJ be used as direct replacements for TCFGA1D105M8R?

A: Yes. Both parts meet all mandatory electrical and mechanical specifications: 1 µF capacitance, ±20% tolerance, 20 V rating, 1206 package, identical physical dimensions, -55°C to 125°C operating range, and ROHS3 compliance. The obsolete TCFGA1D105M8R can be directly substituted with either part without circuit redesign.

Q: What is the difference between TPSA105M020R3000 and TRJA105M020RRJ?
