ECS-T1AC226R Equivalent & Substitute Parts

Part Overview

The ECS-T1AC226R is a 22 µF molded tantalum capacitor rated at 10 V with ±20% tolerance, manufactured by Panasonic Electronic Components in the 2312 (6032 Metric) package. This part is classified as obsolete, making equivalent and substitute components necessary for ongoing design support and procurement.

Molded tantalum capacitors in this specification are used in general-purpose applications requiring compact surface-mount solutions with stable performance across the -55°C to 125°C operating temperature range. The obsolete status of the ECS-T1AC226R necessitates identification of active alternative components that maintain electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECS-T1AC226R is determined by the following criteria:

Primary Compatibility Parameters:

• Capacitance: 22 µF (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)

Secondary Compatibility Parameters:

• Voltage - Rated: 10 V or higher (equal or greater voltage rating acceptable)
• Tolerance: ±20% or tighter (equal or tighter tolerance acceptable)
• Type: Molded tantalum (exact match required)

Substitute parts are grouped into two categories:

Direct Equivalents (Identical Electrical Specifications): Parts matching 22 µF, ±20% tolerance, 10 V rating, and 2312 package with active product status.

Functional Substitutes (Higher Voltage or Tighter Tolerance): Parts with 22 µF capacitance, 2312 package, and voltage ratings of 16 V or 20 V, which provide enhanced performance margins while maintaining mechanical and thermal compatibility.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications):

TAJC226M010RNJ and 293D226X0010C2TE3 are direct electrical equivalents to the ECS-T1AC226R, maintaining 22 µF capacitance, ±20% tolerance, and 10 V rating. Both parts are active products with ROHS3 compliance, addressing the obsolescence and RoHS non-compliance of the original part. The 293D226X0010C2TE3 offers lower ESR (1.5Ohm versus 1.8Ohm), which may provide marginal performance benefits in high-frequency applications.

For Enhanced Performance Margin:

F931C226MCC provides a 16 V rating with the same 22 µF capacitance and ±20% tolerance, offering increased voltage headroom. The 1.1Ohm ESR is the lowest among all substitutes, suitable for applications requiring reduced impedance.

TAJC226K020RNJ provides a 20 V rating with tighter ±10% tolerance and 22 µF capacitance, delivering maximum voltage margin and improved capacitance stability. This part is appropriate for designs requiring enhanced reliability or stricter tolerance control.

All substitute parts maintain the 2312 (6032 Metric) package, -55°C to 125°C operating temperature range, and MSL 1 rating, ensuring mechanical and thermal compatibility with the original design.

Frequently Asked Questions (FAQ)

Q: Can TAJC226K020RNJ be used as a direct replacement for ECS-T1AC226R?

A: Yes. TAJC226K020RNJ is mechanically and electrically compatible. It provides higher voltage rating (20 V versus 10 V) and tighter tolerance (±10% versus ±20%), both of which are acceptable enhancements. The 2312 package, surface-mount configuration, and operating temperature range are identical.

Q: What is the difference between the 10 V and 16 V rated substitutes?

A: Both maintain 22 µF capacitance and ±20% tolerance. The 16 V rated F931C226MCC provides additional voltage margin and lower ESR (1.1Ohm). Selection depends on circuit voltage requirements and impedance specifications.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts are ROHS3 compliant, addressing the RoHS non-compliance of the obsolete ECS-T1AC226R.

Q: Does the increased height of substitute parts affect PCB layout?

A: Substitute parts have a maximum seated height of 0.110" (2.80mm) compared to the original 0.098" (2.50mm). This 0.012" (0.30mm) increase is minimal and typically does not impact standard PCB designs. Verify clearance in height-constrained applications.

Q: Which substitute offers the lowest ESR?

A: F931C226MCC offers the lowest ESR at 1.1Ohm @ 100kHz, followed by 293D226X0010C2TE3 at 1.5Ohm. Lower ESR reduces impedance and heat generation in high-frequency applications.

Q: Can substitutes be used interchangeably in existing designs?

A: Direct equivalents (TAJC226M010RNJ and 293D226X0010C2TE3) are interchangeable with the original part. Higher-rated substitutes (F931C226MCC and TAJC226K020RNJ) are compatible but provide enhanced specifications. Verify circuit design margins before implementation.
