Key Parameters

Substitute Part Grouping Explanation

Substitution for the TAP156K025SCS is determined by the following criteria:

Electrical Parameters (Must Match):

• Capacitance: 15 µF
• Tolerance: ±10%
• Type: Conformal Coated
• Operating Temperature Range: -55°C ~ 125°C

Mechanical Parameters (Must Match):

• Mounting Type: Through Hole
• Package / Case: Radial

Allowable Variations:

• Voltage Rating: Lower voltage ratings are acceptable if the application does not require the full 25 V rating
• ESR: Variations permitted within component specifications
• Packaging Format: Bulk or Cut Tape formats are interchangeable for component selection
• Lead Spacing: Minor variations acceptable based on PCB layout requirements

Two substitute parts meet these criteria: TAP156K006SCS (lower voltage rating) and TAP156K025BRW (identical electrical specifications, different packaging format).

Parameter Comparison

Engineering Selection Recommendations

TAP156K025BRW is the direct electrical equivalent to TAP156K025SCS. Both components share identical capacitance, voltage rating, tolerance, ESR, and physical dimensions. The only difference is packaging format: TAP156K025BRW is supplied in Cut Tape format while TAP156K025SCS is supplied in Bulk. Both are Active status products with ROHS3 compliance. Selection between these two depends on assembly process requirements and inventory management practices.

TAP156K006SCS is a lower voltage variant (6.3 V vs. 25 V) with identical capacitance and tolerance. This substitute is applicable only in applications where the circuit voltage does not exceed 6.3 V. The TAP156K006SCS has a smaller physical footprint (0.197" diameter vs. 0.236" diameter) and higher ESR (5 Ohm vs. 2 Ohm). Both are Active status products with ROHS3 compliance.

All three parts maintain identical operating temperature ranges, lifetime specifications, and regulatory compliance status.

Frequently Asked Questions (FAQ)

Q: Can TAP156K025BRW replace TAP156K025SCS directly? A: Yes. TAP156K025BRW is electrically and mechanically identical to TAP156K025SCS. The only difference is packaging format (Cut Tape vs. Bulk). Direct substitution is valid for applications using automated assembly equipment compatible with Cut Tape format.

Q: When is TAP156K006SCS a valid substitute? A: TAP156K006SCS is valid only when the circuit operating voltage does not exceed 6.3 V. The lower voltage rating makes this part unsuitable for 25 V applications. The smaller physical dimensions may also require PCB layout verification.

Q: What is the impact of different ESR values? A: TAP156K006SCS has 5 Ohm ESR compared to 2 Ohm for the main part. Higher ESR increases heat dissipation and may affect circuit performance in high-frequency or high-current applications. Verify ESR compatibility with circuit requirements before substitution.

Q: Are there lead spacing differences to consider? A: Yes. TAP156K025SCS and TAP156K006SCS have 0.098" (2.50mm) lead spacing, while TAP156K025BRW has 0.197" (5.00mm) lead spacing. PCB footprint compatibility must be confirmed before substitution.

Q: Do all three parts meet the same compliance standards? A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and classified as Active products. Regulatory compliance is equivalent across all options.
