Equivalent & Substitute Parts for ECS-H1ED106R

Part Overview

The ECS-H1ED106R is a 10 µF molded tantalum capacitor rated at 25 V in a 2917 (7343 Metric) surface mount package, manufactured by Panasonic Electronic Components as part of the TEH series. 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 electrical compatibility across capacitance, voltage rating, tolerance, and physical dimensions while meeting modern compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECS-H1ED106R is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Capacitance: 10 µF (exact match required)
• Voltage Rating: 25 V minimum (equal or higher acceptable)
• Tolerance: ±20% or tighter (±10% acceptable as improvement)
• Package / Case: 2917 (7343 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature: -55°C ~ 125°C (exact match required)
• Physical Dimensions: 0.287" L x 0.169" W (7.30mm x 4.30mm) (exact match required)

Substitute Classification:

• Direct Equivalents: Parts meeting all primary criteria with identical or superior electrical specifications
• Similar Parts: Parts meeting all primary criteria with minor parameter variations (tolerance tightening, voltage rating increase) that do not compromise circuit functionality

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Recommended for Direct Replacement):

F971E106MNC and 293D106X0025D2TE3 provide direct electrical equivalence to the ECS-H1ED106R with identical capacitance (10 µF), tolerance (±20%), and voltage rating (25 V). Both parts are in active production status and ROHS3 compliant, addressing the obsolescence and compliance limitations of the original part. F971E106MNC carries AEC-Q200 automotive qualification, suitable for applications requiring high reliability standards.

Compatible Alternatives (Acceptable with Design Verification):

TAJD106M025RNJ maintains electrical equivalence with a marginal increase in ESR (1.2 Ohm versus 1 Ohm for alternatives) and is ROHS3 compliant and active. This part is suitable where ESR tolerance permits.

293D106X9025D2TE3 offers improved tolerance (±10% versus ±20%) at the same voltage and capacitance ratings, providing tighter performance specifications. This part is ROHS3 compliant and active.

TAJD106K035RNJ provides a higher voltage rating (35 V versus 25 V) with improved tolerance (±10%), making it suitable for applications where voltage margin enhancement is beneficial. This part is ROHS3 compliant and active.

All substitute parts maintain the 2917 (7343 Metric) package footprint, surface mount configuration, and -55°C ~ 125°C operating temperature range required for direct board-level compatibility.

Frequently Asked Questions (FAQ)

Q: Can F971E106MNC replace ECS-H1ED106R directly?

A: Yes. F971E106MNC matches all critical electrical parameters (10 µF, ±20%, 25 V) and physical dimensions (2917 package, surface mount). It is active in production and ROHS3 compliant, addressing the obsolescence of the original part.

Q: What is the difference between the KYOCERA AVX and Vishay Sprague options?

A: Both manufacturers provide equivalent parts meeting the 10 µF, ±20%, 25 V specification. KYOCERA AVX F971E106MNC includes AEC-Q200 automotive qualification. Vishay Sprague 293D106X0025D2TE3 is a general-purpose equivalent. Selection depends on application requirements and supply chain preferences.

Q: Can TAJD106K035RNJ be used instead of ECS-H1ED106R?

A: Yes, with design consideration. TAJD106K035RNJ provides the same 10 µF capacitance and 2917 package but with a higher 35 V rating and tighter ±10% tolerance. The increased voltage rating provides additional design margin and does not compromise circuit functionality in applications rated for 25 V operation.

Q: What does the tolerance difference between ±20% and ±10% mean for circuit performance?

A: Tolerance defines the allowable deviation from the nominal capacitance value. A ±20% tolerance permits capacitance between 8 µF and 12 µF, while ±10% permits 9 µF to 11 µF. Tighter tolerance (±10%) provides more predictable performance in applications sensitive to capacitance variation.

Q: Are there packaging format differences I should consider?

A: Yes. F971E106MNC and 293D106X0025D2TE3 are supplied in Tape & Reel (TR) format for automated assembly. TAJD106M025RNJ, 293D106X9025D2TE3, and TAJD106K035RNJ are supplied in Cut Tape (CT) & Digi-Reel® format. Packaging selection depends on production volume and assembly equipment compatibility.

Q: Is the ESR (Equivalent Series Resistance) specification critical for substitution?

A: ESR is provided for reference but is not a primary substitution criterion for this part category. The original ECS-H1ED106R does not specify ESR. Substitute parts with ESR values of 1 Ohm to 1.2 Ohm are functionally equivalent for general-purpose applications.
