Lifetime @ Temp.: 1000 Hrs @ 85°C (all substitutes maintain this specification)
Series: TAP (all substitutes belong to the same series)
RoHS Status: ROHS3 Compliant (all substitutes maintain compliance)

Variable Parameters (Basis for Substitution):

Voltage - Rated: 6.3 V, 10 V, or 16 V (lower than the main part's 50 V)

Engineering Selection Recommendations

Selection of substitute parts for the TAP106K050SCS must be based on application voltage requirements and tolerance specifications:

TAP106K006SCS (10 µF, ±10%, 6.3 V): Suitable for applications operating at 6.3 V or lower. The ±10% tolerance maintains precision equivalent to the main part. Physical dimensions are reduced (0.177" diameter, 0.295" height), enabling space-constrained designs. ESR of 6 Ohm is higher than the main part.

TAP106K010SCS (10 µF, ±10%, 10 V): Applicable to circuits with 10 V maximum operating voltage. The ±10% tolerance specification matches the main part. Intermediate physical dimensions (0.197" diameter, 0.335" height) provide moderate space efficiency. ESR of 5 Ohm represents a middle-range value.

TAP106K016SCS (10 µF, ±10%, 16 V): Designed for applications requiring up to 16 V operation. The ±10% tolerance maintains precision. Physical dimensions (0.197" diameter, 0.354" height) are compact relative to the main part. ESR of 3.2 Ohm is lower, improving performance in high-frequency applications.

TAP106M006SCS (10 µF, ±20%, 6.3 V): Intended for 6.3 V applications where ±20% tolerance is acceptable. Reduced physical dimensions match TAP106K006SCS. ESR of 6 Ohm is identical to the K-tolerance variant.

TAP106M016SCS (10 µF, ±20%, 16 V): Applicable to 16 V circuits with relaxed tolerance requirements (±20%). Physical dimensions match TAP106K016SCS. ESR of 3.2 Ohm provides low-impedance performance.

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and identical operating temperature range (-55°C ~ 125°C). Selection must confirm that the application's maximum operating voltage does not exceed the substitute part's rated voltage.

Frequently Asked Questions (FAQ)

Q: Can TAP106K050SCS be replaced with a lower voltage-rated substitute? A: Yes, provided the application's actual operating voltage does not exceed the substitute part's rated voltage. The TAP106K006SCS, TAP106K010SCS, and TAP106K016SCS are electrically compatible at their respective voltage ratings. Physical dimensions will be smaller, which may require PCB layout verification.

Q: What is the difference between K-tolerance and M-tolerance variants? A: K-tolerance parts (TAP106K006SCS, TAP106K010SCS, TAP106K016SCS) specify ±10% capacitance tolerance. M-tolerance parts (TAP106M006SCS, TAP106M016SCS) specify ±20% capacitance tolerance. Selection depends on circuit requirements for capacitance precision.

Q: Are all substitute parts mechanically compatible with the original PCB footprint? A: No. Substitute parts have different physical dimensions. TAP106K006SCS and TAP106M006SCS are 0.177" diameter (4.50 mm), while TAP106K010SCS, TAP106K016SCS, and TAP106M016SCS are 0.197" diameter (5.00 mm). The main part TAP106K050SCS is 0.315" diameter (8.00 mm). PCB footprint verification is required before substitution.

Q: Do all substitute parts maintain the same lead spacing? A: Yes. All substitute parts maintain 0.098" (2.50 mm) lead spacing, ensuring compatibility with standard through-hole PCB patterns designed for the TAP series.

Q: What is the impact of ESR differences on circuit performance? A: ESR (Equivalent Series Resistance) varies among substitutes. The main part TAP106K050SCS has 1.6 Ohm ESR. Substitutes range from 3.2 Ohm to 6 Ohm. Higher ESR increases impedance at high frequencies and may affect ripple current performance. Circuit analysis is required for applications sensitive to ESR characteristics.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All substitute parts listed are ROHS3 compliant and REACH unaffected, maintaining regulatory compliance equivalent to the main part.

Q: What operating temperature range applies to substitute parts? A: All substitute parts operate across -55°C ~ 125°C with 1000 hours lifetime at 85°C, identical to the main part TAP106K050SCS.
