Substitute Part Grouping Explanation

Substitution of the TAP155K050SCS is permissible with the TAP155K016SCS based on the following criteria:

Matching Parameters (Required for Substitution):

• Capacitance: 1.5 µF (identical)
• Tolerance: ±10% (identical)
• Type: Conformal Coated (identical)
• Operating Temperature Range: -55°C ~ 125°C (identical)
• Mounting Type: Through Hole (identical)
• Package / Case: Radial (identical)
• Lead Spacing: 0.098" (2.50mm) (identical)
• Series: TAP (identical)
• Product Status: Active (identical)
• RoHS Status: ROHS3 Compliant (identical)

Differing Parameters (Application-Dependent):

• Voltage - Rated: 50 V (main) vs. 16 V (substitute)
• ESR: 6 Ohm (main) vs. 10 Ohm (substitute)
• Physical Size: 0.197" Dia × 0.354" H (main) vs. 0.177" Dia × 0.276" H (substitute)
• Manufacturer Size Code: D (main) vs. A (substitute)

The substitute part is suitable for applications where the operating voltage does not exceed 16 V and where the higher ESR of 10 Ohm is acceptable for the circuit design.

Parameter Comparison

Engineering Selection Recommendations

Both the TAP155K050SCS and TAP155K016SCS maintain Active product status and are ROHS3 compliant with REACH unaffected classification. Selection between these parts is determined by circuit voltage requirements and physical space constraints.

The TAP155K050SCS is the primary choice for applications requiring 50 V rated voltage with lower ESR performance. The TAP155K016SCS serves as a substitute only in circuits where the maximum operating voltage does not exceed 16 V, offering a more compact footprint (0.177" diameter vs. 0.197" diameter) and reduced height (0.276" vs. 0.354"). The increased ESR of 10 Ohm in the substitute part must be evaluated against circuit performance specifications.

Both parts share identical lead spacing (0.098" / 2.50mm), enabling direct PCB footprint compatibility when voltage and ESR requirements are satisfied.

Frequently Asked Questions (FAQ)

Q: Can TAP155K016SCS replace TAP155K050SCS in all applications?

A: No. The substitute part is rated for 16 V maximum, making it unsuitable for circuits designed for 50 V operation. Substitution is only valid when the circuit voltage does not exceed 16 V.

Q: What is the impact of the ESR difference between these parts?

A: The TAP155K050SCS has 6 Ohm ESR while the TAP155K016SCS has 10 Ohm ESR. Higher ESR increases heat dissipation and may affect circuit performance in high-frequency or high-current applications. Circuit analysis is required to determine acceptability.

Q: Are the physical dimensions compatible with the same PCB footprint?

A: Both parts have identical lead spacing (0.098" / 2.50mm), allowing use of the same PCB pad pattern. However, the TAP155K016SCS is physically smaller (0.177" diameter, 0.276" height) compared to the TAP155K050SCS (0.197" diameter, 0.354" height), which may affect component placement in space-constrained designs.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the TAP155K050SCS and TAP155K016SCS are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS code 8532.21.0040.

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

A: Both parts operate across -55°C to 125°C with a lifetime specification of 1000 hours at 85°C.
