TAP225M016GSB Equivalent & Substitute Parts

Part Overview

The TAP225M016GSB is a 2.2 µF conformal coated tantalum capacitor rated at 16 V with ±20% tolerance, manufactured by KYOCERA AVX in the TAP series. This radial through-hole component is designed for general-purpose applications requiring reliable capacitance in compact form factors. The part is currently active in production with 998 units in stock. Substitute parts are identified when design requirements allow for parameter variations within acceptable electrical and mechanical tolerances, or when inventory availability necessitates alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TAP225M016GSB are identified based on the following criteria:

Electrical Compatibility Parameters:

• Capacitance value: 2.2 µF (fixed requirement)
• Voltage rating: Equal to or greater than 16 V
• Tolerance: ±20% or tighter
• ESR: 8 Ohm or lower
• Type: Conformal Coated
• Operating temperature range: -55°C ~ 125°C minimum

Mechanical Compatibility Parameters:

• Mounting type: Through Hole
• Package / Case: Radial
• Size / Dimension: 0.177" Dia (4.50mm)
• Height - Seated (Max): 0.335" (8.50mm)
• Lead spacing: 0.125" (3.18mm) or 0.197" (5.00mm)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• Product Status: Active

Two substitute parts meet these criteria: TAP225K025GSB (upgrade option with higher voltage rating and tighter tolerance) and TAP225M016CCS (direct equivalent with alternative lead spacing).

Parameter Comparison

Engineering Selection Recommendations

TAP225K025GSB (Upgrade Substitute): This part provides enhanced electrical performance with a 25 V voltage rating (56% higher than the original 16 V specification) and ±10% tolerance (tighter than the original ±20%). The ESR is reduced to 6 Ohm compared to 8 Ohm in the main part. All mechanical dimensions and lead spacing remain identical to the original TAP225M016GSB. This part is suitable for applications requiring improved voltage margin or tighter capacitance tolerance. The part is ROHS3 compliant and active in production with 2934 units in stock.

TAP225M016CCS (Direct Equivalent): This part maintains identical electrical specifications to the TAP225M016GSB (2.2 µF, 16 V, ±20%, 8 Ohm ESR). The primary difference is the lead spacing, which is 0.197" (5.00mm) instead of 0.125" (3.18mm). This part is suitable for applications where PCB layout accommodates the wider lead spacing. The part is ROHS3 compliant and active in production with 1340 units in stock.

Frequently Asked Questions (FAQ)

Q: Can TAP225K025GSB be used as a direct replacement for TAP225M016GSB?

A: Yes, with design considerations. The TAP225K025GSB is electrically compatible and mechanically identical in size and height. The 25 V rating provides additional voltage margin above the 16 V requirement. The ±10% tolerance is tighter than the original ±20%, and the 6 Ohm ESR is lower than the original 8 Ohm. Lead spacing remains at 0.125" (3.18mm), matching the original part. No PCB layout modifications are required.

Q: What is the difference between TAP225M016GSB and TAP225M016CCS?

A: Both parts have identical electrical specifications: 2.2 µF capacitance, 16 V rating, ±20% tolerance, and 8 Ohm ESR. The difference is in lead spacing: TAP225M016GSB has 0.125" (3.18mm) spacing, while TAP225M016CCS has 0.197" (5.00mm) spacing. Selection depends on PCB footprint design. Both are ROHS3 compliant and active in production.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. Both TAP225K025GSB and TAP225M016CCS are ROHS3 compliant, matching the compliance status of the main part TAP225M016GSB.

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

A: All three parts (TAP225M016GSB, TAP225K025GSB, and TAP225M016CCS) operate across the same temperature range: -55°C to 125°C.

Q: How does ESR affect part selection?

A: ESR (Equivalent Series Resistance) impacts circuit performance in high-frequency or high-current applications. The TAP225K025GSB has a lower ESR of 6 Ohm compared to 8 Ohm in both TAP225M016GSB and TAP225M016CCS. Lower ESR reduces heat generation and improves transient response. Selection should be based on circuit requirements.

Q: Can lead spacing differences affect circuit performance?

A: Lead spacing affects PCB layout and mechanical fit only. Electrically, the 0.125" (3.18mm) and 0.197" (5.00mm) lead spacings do not impact capacitor performance. Selection is determined by PCB footprint design and available board space.
