Substitute Part Grouping Explanation

Substitute parts for the T97F226M063ESS are qualified based on the following criteria:

Identical capacitance value: 22 µF
Identical voltage rating: 63 V
Identical package / case: 3024 (7660 Metric)
Identical ESR: 250 mOhm
Identical operating temperature range: -55°C to 85°C
Identical mounting type: Surface Mount
Identical conformal coating type
Identical series designation: TANTAMOUNT™, T97
Tolerance variation: ±10% (tighter than the main part's ±20%)

The three substitute parts (T97F226K063EAB, T97F226K063LSA, T97F226K063LSB) maintain all critical electrical and mechanical parameters. The primary distinction is the tolerance specification, where substitute parts feature ±10% tolerance compared to the main part's ±20% tolerance. This represents an improvement in capacitance accuracy and does not restrict substitution compatibility.

Engineering Selection Recommendations

All substitute parts maintain Active product status and are manufactured by Vishay Sprague within the TANTAMOUNT™ T97 series. The substitute parts T97F226K063EAB, T97F226K063LSA, and T97F226K063LSB are electrically and mechanically equivalent to the main part T97F226M063ESS.

Selection among substitute parts may be based on packaging format availability:

T97F226K063EAB: Available in Cut Tape (CT) & Digi-Reel® packaging
T97F226K063LSA: Available in Tape & Reel (TR) packaging
T97F226K063LSB: Available in Tape & Reel (TR) packaging

All parts carry identical compliance designations (ECCN: EAR99, HTSUS: 8532.21.0050) and share the same moisture sensitivity level. The tighter tolerance specification (±10%) of substitute parts provides improved capacitance accuracy compared to the main part's ±20% tolerance, which does not restrict their use as direct substitutes.

Frequently Asked Questions (FAQ)

Q: Can T97F226K063EAB, T97F226K063LSA, and T97F226K063LSB be used interchangeably with T97F226M063ESS?

A: Yes. All substitute parts maintain identical electrical parameters (22 µF capacitance, 63 V rating, 250 mOhm ESR), mechanical dimensions (3024 package, 7.60mm x 6.00mm), and operating specifications (-55°C to 85°C). The substitute parts feature ±10% tolerance, which is tighter than the main part's ±20% tolerance and does not restrict substitution.

Q: What is the difference between the packaging options for substitute parts?

A: T97F226K063EAB is supplied in Cut Tape (CT) & Digi-Reel® format, while T97F226K063LSA and T97F226K063LSB are supplied in Tape & Reel (TR) format. The electrical and mechanical specifications are identical; packaging selection depends on assembly line requirements and quantity needs.

Q: Are there any compliance or regulatory differences between the main part and substitute parts?

A: No. All parts share identical compliance designations (ECCN: EAR99, HTSUS: 8532.21.0050) and RoHS status (non-compliant). Moisture sensitivity level is identical at 2A (4 Weeks) for all parts.

Q: Does the ±10% tolerance of substitute parts affect circuit design?

A: The ±10% tolerance of substitute parts is tighter than the main part's ±20% tolerance. This represents improved accuracy and does not introduce design constraints. Circuits designed for the main part's ±20% tolerance will operate within specification with substitute parts.

Q: What inventory levels are available for each part?

A: Current inventory levels are: T97F226M063ESS (1,159 pcs), T97F226K063EAB (1,640 pcs), T97F226K063LSA (2,451 pcs), and T97F226K063LSB (895 pcs).
