TAP225M050CCS Equivalent & Substitute Parts

Part Overview

The TAP225M050CCS is a 2.2 µF conformal coated tantalum capacitor rated at 50 V with radial through-hole mounting. This component is designed for general-purpose applications requiring reliable energy storage in compact form factors. The part is currently active in production with full ROHS3 compliance and REACH unaffected status. Substitute parts may be required due to inventory constraints, application voltage derating requirements, or design optimization for specific circuit conditions.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TAP225M050CCS is determined by strict adherence to the following electrical and mechanical parameters:

Mandatory Matching Parameters:

• Capacitance: 2.2 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Type: Conformal Coated (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial (exact match required)
• Lead Spacing: 0.197" (5.00mm) (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

Allowable Variation Parameters:

• Voltage - Rated: May be lower than 50 V for applications operating below the original rated voltage
• ESR (Equivalent Series Resistance): May vary based on voltage rating and physical size
• Size / Dimension: May vary based on voltage rating and ESR characteristics
• Height - Seated (Max): May vary based on voltage rating and physical size

The substitute part TAP225M016CCS meets all mandatory matching parameters while operating at a reduced voltage rating of 16 V, suitable for circuits where the application voltage does not exceed this threshold.

Parameter Comparison

Engineering Selection Recommendations

Both TAP225M050CCS and TAP225M016CCS are active production parts with full ROHS3 compliance and REACH unaffected status, ensuring regulatory compliance for current and future applications.

Selection between these parts is determined by circuit voltage requirements. The TAP225M050CCS is specified for applications requiring 50 V rated voltage. The TAP225M016CCS is suitable only for circuits where the maximum applied voltage does not exceed 16 V.

Physical dimensions differ between the two parts. The TAP225M050CCS occupies a larger footprint (0.217" diameter, 0.413" height) compared to the TAP225M016CCS (0.177" diameter, 0.335" height). PCB layout and mechanical clearance must accommodate the selected part's physical dimensions.

ESR characteristics differ between parts due to voltage rating and physical size variations. The TAP225M050CCS exhibits 4.6 Ohm ESR while the TAP225M016CCS exhibits 8 Ohm ESR. Circuit performance sensitive to ESR values must account for this difference.

Frequently Asked Questions (FAQ)

Q: Can TAP225M016CCS replace TAP225M050CCS in any application?

A: TAP225M016CCS can replace TAP225M050CCS only in circuits where the maximum applied voltage does not exceed 16 V. The 16 V rating is a hard limit; exceeding this voltage will damage the component. If your circuit operates at voltages above 16 V, TAP225M016CCS is not suitable.

Q: What is the physical difference between these two parts?

A: TAP225M050CCS measures 0.217" diameter with 0.413" maximum seated height. TAP225M016CCS measures 0.177" diameter with 0.335" maximum seated height. Both maintain identical 0.197" lead spacing. The smaller TAP225M016CCS may fit in space-constrained layouts where the larger TAP225M050CCS cannot.

Q: Why does TAP225M016CCS have higher ESR than TAP225M050CCS?

A: ESR variation is inherent to the physical design differences between voltage-rated variants. The TAP225M050CCS exhibits 4.6 Ohm ESR while TAP225M016CCS exhibits 8 Ohm ESR. Applications sensitive to ESR performance must evaluate this parameter during selection.

Q: Are both parts RoHS compliant?

A: Yes. Both TAP225M050CCS and TAP225M016CCS are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Do these parts have identical lead spacing?

A: Yes. Both parts maintain 0.197" (5.00mm) lead spacing, allowing direct PCB footprint compatibility. However, the different body diameters and heights must be considered for mechanical clearance.
