TAP104K035SRS Equivalent & Substitute Parts

Part Overview

The TAP104K035SRS is a 0.1 µF conformal coated tantalum capacitor rated for 35 V operation in a radial through-hole package. This component is classified as Active product status and is suitable for general-purpose applications requiring reliable energy storage in compact form factors. Substitute parts become necessary when design requirements demand higher voltage ratings, improved inventory availability, or when the primary part reaches end-of-life status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TAP104K035SRS is determined by strict equivalence in the following parameters:

• Capacitance Value: Must remain 0.1 µF (no tolerance deviation)
• Tolerance: Must remain ±10%
• Type: Must remain Conformal Coated
• ESR: Must remain 26 Ohm
• Operating Temperature Range: Must remain -55°C ~ 125°C
• Mounting Type: Must remain Through Hole
• Package / Case: Must remain Radial
• Physical Dimensions: Must match 0.177" Dia (4.50mm), 0.276" (7.00mm) height, and 0.098" (2.50mm) lead spacing

The TAP104K050SRS qualifies as a direct substitute because it maintains all critical parameters while providing an upgraded voltage rating of 50 V (compared to 35 V). This higher voltage rating is a forward-compatible upgrade that does not compromise any electrical or mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The TAP104K050SRS serves as a direct substitute for the TAP104K035SRS in all applications where the original 35 V rating is specified. Both components maintain Active product status and full ROHS3 compliance, ensuring regulatory continuity. The higher voltage rating of the TAP104K050SRS provides additional design margin without introducing any mechanical or electrical incompatibilities. Selection between these parts should be based on circuit voltage requirements and inventory availability rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Can TAP104K050SRS replace TAP104K035SRS in existing designs?

A: Yes. The TAP104K050SRS is electrically and mechanically compatible with the TAP104K035SRS. The 50 V rating is a forward-compatible upgrade that does not affect circuit operation when the original design voltage is 35 V or lower.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both components share identical radial package dimensions: 0.177" diameter (4.50mm), 0.276" maximum seated height (7.00mm), and 0.098" lead spacing (2.50mm). PCB layout and mounting procedures remain unchanged.

Q: Do both parts meet the same compliance standards?

A: Yes. Both TAP104K035SRS and TAP104K050SRS are ROHS3 compliant and REACH unaffected, maintaining identical regulatory status.

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

A: The sole difference is the voltage rating: TAP104K035SRS is rated for 35 V operation, while TAP104K050SRS is rated for 50 V operation. All other electrical and mechanical specifications remain identical.

Q: Should I use the higher voltage part if available?

A: Component selection should follow circuit design specifications. If the circuit operates at 35 V or below, either part is suitable. Higher voltage ratings do not improve performance in lower-voltage applications but may be selected based on inventory or supply chain considerations.
