ECS-T1EC106R Equivalent & Substitute Parts

Part Overview

The ECS-T1EC106R is a 10 µF molded tantalum capacitor rated at 25 V in a 2312 (6032 Metric) surface mount package, manufactured by Panasonic Electronic Components. This component is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and production continuity. Substitute parts must maintain identical electrical specifications and mechanical compatibility to ensure direct replacement without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECS-T1EC106R is determined by the following mandatory parameters:

• Capacitance: 10 µF (exact match required)
• Voltage Rating: 25 V (exact match required)
• Package / Case: 2312 (6032 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (minimum requirement)

The substitute parts identified below meet these core electrical and mechanical requirements. Tolerance variations (±20% vs. ±10%) and ESR specifications are secondary parameters that may differ while maintaining functional compatibility. All substitute parts are manufactured by KYOCERA AVX and are available in active product status.

Parameter Comparison

Engineering Selection Recommendations

F931E106MCC is the primary substitute for the ECS-T1EC106R. This part maintains identical electrical specifications (10 µF, ±20%, 25 V) and mechanical compatibility (2312 package, surface mount). F931E106MCC is in active production status and carries ROHS3 compliance certification, making it suitable for new designs and production environments with RoHS requirements. The ESR specification of 1.5 Ohm @ 100kHz is lower than the other alternatives, providing improved performance characteristics.

TAJC106K025RNJ offers tighter tolerance (±10%) compared to the original part (±20%), which may be beneficial in applications requiring higher capacitance accuracy. This part is in active production status and ROHS3 compliant. The ESR specification is 1.8 Ohm.

TAJC106M025HNJ maintains the original tolerance specification (±20%) and is in active production status. However, this part carries RoHS non-compliant status, matching the original part's compliance profile. This option is suitable for legacy system support where RoHS compliance is not a requirement.

All three substitute parts are manufactured by KYOCERA AVX and are available in active product status, ensuring long-term supply chain reliability compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can F931E106MCC be used as a direct replacement for ECS-T1EC106R?

A: Yes. F931E106MCC meets all mandatory substitution criteria: 10 µF capacitance, 25 V voltage rating, 2312 (6032 Metric) package, and surface mount configuration. Both parts operate across the -55°C to 125°C temperature range and are mechanically compatible.

Q: What is the difference between TAJC106K025RNJ and TAJC106M025HNJ?

A: The primary difference is tolerance specification. TAJC106K025RNJ has ±10% tolerance, while TAJC106M025HNJ has ±20% tolerance (matching the original part). Both parts are electrically and mechanically equivalent otherwise. Selection depends on application requirements for capacitance accuracy.

Q: Does the height difference between the original part (0.098") and substitute parts (0.110") affect compatibility?

A: The substitute parts have a maximum seated height of 0.110" compared to the original 0.098". This 0.012" (0.30mm) difference must be evaluated against PCB layout constraints and clearance requirements. Verify that the increased height does not interfere with adjacent components or enclosure design before implementation.

Q: Are all substitute parts RoHS compliant?

A: F931E106MCC and TAJC106K025RNJ are ROHS3 compliant. TAJC106M025HNJ is RoHS non-compliant, matching the original part's compliance status. Selection should align with your product's regulatory requirements.

Q: What is the significance of ESR specifications in the substitute parts?

A: ESR (Equivalent Series Resistance) affects capacitor performance in high-frequency applications and ripple current handling. F931E106MCC has the lowest ESR at 1.5 Ohm @ 100kHz, while both TAJ variants specify 1.8 Ohm. The original part does not specify ESR. For applications sensitive to ESR performance, F931E106MCC is the preferred choice.

Q: Are these substitute parts available in different packaging options?

A: F931E106MCC and TAJC106K025RNJ are available in Cut Tape (CT) & Digi-Reel® packaging. TAJC106M025HNJ is available in Tape & Reel (TR) packaging. Packaging selection depends on your procurement and assembly process requirements.
