ECS-T1DX106R Equivalent & Substitute Parts

Part Overview

The ECS-T1DX106R is a 10 µF molded tantalum capacitor rated at 20 V, manufactured by Panasonic Electronic Components in the TE series. This component is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and production continuity. The part is housed in a 1411 (3528 Metric) surface mount package with ±20% capacitance tolerance and operates across the temperature range of -55°C to 125°C. Substitute parts must maintain electrical and mechanical compatibility while meeting current availability and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECS-T1DX106R is determined by strict alignment of the following electrical and mechanical parameters:

• Capacitance value: 10 µF (exact match required)
• Voltage rating: 20 V (exact match required)
• Package / Case: 1411 (3528 Metric) (exact match required)
• Mounting type: Surface Mount (exact match required)
• Operating temperature range: -55°C to 125°C (exact match required)
• Tolerance: ±20% or tighter (±10% is acceptable as a tighter specification)

Substitute parts are classified into two categories:

Direct Substitutes: Parts meeting all electrical and mechanical parameters with active product status and current RoHS compliance.

Similar Substitutes: Parts meeting all core electrical and mechanical parameters with active product status and current RoHS compliance, with minor variations in secondary specifications.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are suitable replacements for the obsolete ECS-T1DX106R based on electrical and mechanical parameter alignment. Selection should be based on the following criteria:

F931D106MBA (KYOCERA AVX): This direct substitute maintains the ±20% tolerance specification of the original part. It is ROHS3 compliant and actively manufactured. The seated height of 0.091" (2.30mm) is slightly elevated compared to the original 0.075" (1.90mm); PCB layout clearance must be verified.

TAJB106K020RNJ (KYOCERA AVX): This direct substitute offers improved tolerance specification at ±10%, providing tighter capacitance control. It is ROHS3 compliant and actively manufactured with high inventory availability. The seated height of 0.083" (2.10mm) is within acceptable variation. This part is available in both 1411 and 1210 package options.

293D106X9020B2TE3 (Vishay Sprague): This similar substitute offers ±10% tolerance specification and is ROHS3 compliant with active product status. The seated height of 0.083" (2.11mm) is within acceptable variation. This part is part of the TANTAMOUNT™ series.

All substitute parts are ROHS3 compliant, addressing the non-compliance status of the original part. All maintain MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard handling and storage procedures.

Frequently Asked Questions (FAQ)

Q: Can F931D106MBA be used as a direct replacement for ECS-T1DX106R?

A: Yes. F931D106MBA meets all core electrical parameters (10 µF, 20 V, ±20% tolerance) and mechanical specifications (1411 package, surface mount, -55°C to 125°C). The seated height difference of 0.016" (0.40mm) must be evaluated for PCB layout compatibility.

Q: What is the difference between the tolerance specifications of the substitute parts?

A: The original ECS-T1DX106R specifies ±20% tolerance. F931D106MBA maintains this ±20% specification. TAJB106K020RNJ and 293D106X9020B2TE3 both offer ±10% tolerance, which is a tighter specification and provides improved capacitance accuracy. Tighter tolerance does not prevent substitution; it represents an improvement in component specification.

Q: Are all substitute parts RoHS compliant?

A: Yes. All three substitute parts are ROHS3 compliant. The original ECS-T1DX106R is RoHS non-compliant. Substitution with any of these parts addresses RoHS compliance requirements for new designs or production updates.

Q: Does the package designation "1411 (3528 Metric)" differ between parts?

A: No. All parts use the identical 1411 (3528 Metric) package designation with matching footprint dimensions of 0.138" L x 0.110" W (4.60mm x 2.80mm). Seated height varies slightly between parts; maximum heights range from 0.075" to 0.091" (1.90mm to 2.30mm). PCB clearance must be verified for the specific substitute selected.

Q: Can TAJB106K020RNJ be used in applications requiring ±20% tolerance?

A: Yes. TAJB106K020RNJ specifies ±10% tolerance, which is tighter than the ±20% requirement. A component with tighter tolerance meets or exceeds the original specification and is suitable for use in applications designed for ±20% tolerance.

Q: What is the significance of ESR (Equivalent Series Resistance) in substitute selection?

A: The original ECS-T1DX106R does not specify ESR. All substitute parts specify 2.1Ohm ESR, providing defined electrical performance characteristics. This specification does not prevent substitution; it represents additional technical documentation available for the substitute parts.

Q: Are all substitute parts available in the same packaging format?

A: F931D106MBA is available in Tape & Reel (TR) packaging. TAJB106K020RNJ is available in Cut Tape (CT) & Digi-Reel® packaging and also supports 1210 package option. 293D106X9020B2TE3 is available in Cut Tape (CT) & Digi-Reel® packaging. Packaging format selection depends on production requirements and procurement preferences.
