TAJB226K020SNJ Equivalent & Substitute Parts

Part Overview

The TAJB226K020SNJ is a 22 µF molded tantalum capacitor manufactured by KYOCERA AVX, rated for 20 V operation in a 1411 (3528 Metric) surface mount package. This component is classified as Active product status and is designed for general purpose applications requiring stable capacitance and low equivalent series resistance in compact form factors. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling direct replacement in circuit designs without functional compromise.

Substitute Part Grouping Explanation

Substitution eligibility for the TAJB226K020SNJ is determined by strict alignment of the following parameters:

• Capacitance Value: 22 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 ~ 125°C (exact match required)
• Tolerance: ±10% (exact match required)
• RoHS Compliance: ROHS3 Compliant (required for regulatory alignment)

All identified substitute parts meet these core electrical and mechanical criteria. Variations in ESR, MSL rating, and lifetime specifications are noted but do not preclude substitution when the primary parameters align.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts—TAJB226K020RNJV, 293D226X9020B2TE3, and TCKID226BT—are qualified equivalents for the TAJB226K020SNJ based on matching electrical specifications, package geometry, and regulatory compliance. Each part maintains Active product status and ROHS3 compliance.

TAJB226K020RNJV (KYOCERA AVX): Identical manufacturer with matching ESR (1.8 Ohm @ 100kHz) and lifetime rating (2000 Hrs @ 125°C). MSL rating differs at 3 (168 Hours) versus the original MSL 1 (Unlimited), which may impact storage and handling protocols in moisture-sensitive environments.

293D226X9020B2TE3 (Vishay Sprague): Meets all core electrical and mechanical parameters. ESR is specified at 2.1 Ohm, representing a 0.3 Ohm increase from the original specification. Height dimension is 2.11mm versus 2.10mm, a negligible 0.01mm variance. MSL rating is 1 (Unlimited), matching the original part.

TCKID226BT (Cal-Chip Electronics, Inc.): Parametric equivalent with matching ESR (1.8 Ohm) and MSL rating (1, Unlimited). All dimensional and electrical specifications align with the original part.

Selection among these substitutes depends on supply chain availability, inventory levels, and specific application requirements regarding ESR tolerance and moisture sensitivity classification.

Frequently Asked Questions (FAQ)

Q: Can TAJB226K020RNJV be used as a direct replacement for TAJB226K020SNJ?

A: Yes. Both parts are manufactured by KYOCERA AVX with identical capacitance (22 µF), voltage rating (20 V), package (1411), and ESR (1.8 Ohm @ 100kHz). The primary difference is MSL rating: TAJB226K020RNJV is MSL 3 (168 Hours) versus MSL 1 (Unlimited) for the original. This affects moisture absorption limits during storage and handling.

Q: What is the significance of the ESR difference in 293D226X9020B2TE3?

A: The ESR specification of 2.1 Ohm for the Vishay part is 0.3 Ohm higher than the original 1.8 Ohm specification. This represents approximately 17% higher series resistance. In applications where ESR directly impacts performance (ripple current handling, transient response), this variance should be evaluated against circuit requirements.

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

A: Yes. All parts are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. Physical dimensions and mounting footprints are identical across all four parts, with negligible height variance (2.10mm to 2.11mm).

Q: Do all substitute parts meet the same regulatory requirements?

A: Yes. All parts are ROHS3 Compliant, REACH Unaffected, and classified under ECCN EAR99. Regulatory compliance is uniform across the main part and all substitutes.

Q: What is the operating temperature range for these parts?

A: All parts operate across -55°C to 125°C. Lifetime rating for TAJB226K020SNJ and TCKID226BT is specified at 2000 Hrs @ 125°C. The Vishay part (293D226X9020B2TE3) does not specify lifetime data in the provided parameters.
