Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECS-T1AY106R is determined by strict equivalence across the following parameters:

• Capacitance: 10 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage Rating: 10 V (exact match required)
• Package / Case: 1206 (3216 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

All identified substitute parts meet these core electrical and mechanical parameters. Secondary parameters such as ESR (Equivalent Series Resistance), product status, and compliance certifications are provided for engineering evaluation but do not disqualify substitution based on functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts satisfy the core electrical and mechanical requirements for direct replacement of the ECS-T1AY106R. Selection among active alternatives should be based on the following factors:

Product Status and Availability: F931A106MAA, TAJA106M010RNJ, 293D106X0010A2TE3, and T491A106M010AT are all classified as active products with current manufacturing status, ensuring long-term supply chain viability compared to the obsolete ECS-T1AY106R.

Compliance Requirements: All substitute parts are ROHS3 compliant, whereas the original ECS-T1AY106R is RoHS non-compliant. For applications subject to RoHS directives, substitution with any of the four alternatives is necessary.

Physical Dimensions: The substitute parts exhibit a maximum seated height of 0.071" (1.80mm) compared to the original 0.063" (1.60mm). PCB layout and component clearance must accommodate this 0.008" (0.20mm) height increase.

Packaging Options: F931A106MAA is supplied in Tape & Reel (TR) format; TAJA106M010RNJ and T491A106M010AT are supplied in Cut Tape (CT) & Digi-Reel® format; 293D106X0010A2TE3 is supplied in Tape & Reel (TR) format. Selection should align with production assembly requirements.

Frequently Asked Questions (FAQ)

Q: Can any of these substitute parts be used interchangeably with the ECS-T1AY106R?

A: Yes. All four substitute parts meet the core electrical specifications (10 µF, ±20%, 10 V) and mechanical requirements (1206 package, surface mount, -55°C ~ 125°C operating range). Physical height differences must be evaluated for PCB layout compatibility.

Q: What is the significance of the height difference between the original and substitute parts?

A: The ECS-T1AY106R has a maximum seated height of 0.063" (1.60mm), while all substitutes are 0.071" (1.80mm). This 0.008" (0.20mm) increase may affect component placement in space-constrained designs. PCB layout review is necessary to confirm clearance.

Q: Why is RoHS compliance important for this substitution?

A: The original ECS-T1AY106R is RoHS non-compliant. All substitute parts are ROHS3 compliant, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution in regulated markets.

Q: Does ESR (Equivalent Series Resistance) affect substitution suitability?

A: ESR values for the substitutes range from 3Ohm to 3.8Ohm, while the original part does not specify ESR. These values are within typical ranges for molded tantalum capacitors in this class. Application-specific ESR requirements should be evaluated against the provided specifications.

Q: What packaging formats are available for these substitutes?

A: F931A106MAA and 293D106X0010A2TE3 are supplied in Tape & Reel (TR) format. TAJA106M010RNJ and T491A106M010AT are supplied in Cut Tape (CT) & Digi-Reel® format. Selection should align with production assembly equipment and processes.

Q: Are all substitute parts currently in stock?

A: Inventory status at the time of data collection: F931A106MAA (35,300 pcs), TAJA106M010RNJ (35,200 pcs), 293D106X0010A2TE3 (5,400 pcs), T491A106M010AT (1,532 pcs). Current availability should be confirmed with component distributors.
