TAP104M035CRS Equivalent & Substitute Parts

Part Overview

The TAP104M035CRS is a 0.1 µF conformal coated tantalum capacitor rated for 35 V operation in a radial through-hole package. Manufactured by KYOCERA AVX, this component is classified as Active product status and is suitable for general-purpose applications requiring reliable energy storage in compact form factors. Alternative models may be required when design specifications demand higher voltage ratings, improved tolerance characteristics, or different packaging configurations while maintaining the same capacitance value and physical dimensions.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TAP104M035CRS is permissible when the following conditions are met:

Critical Parameters for Substitution:

• Capacitance value must remain 0.1 µF
• Package type must be Radial through-hole
• Physical dimensions (diameter, height, lead spacing) must match: 0.177" Dia (4.50 mm), 0.335" (8.50 mm) height, 0.197" (5.00 mm) lead spacing
• Conformal coated tantalum construction must be maintained
• ESR must remain 26 Ohm
• Operating temperature range must cover -55°C to 125°C

Allowable Variations:

• Voltage rating may be increased above 35 V
• Tolerance may be tightened (improved from ±20%)
• Packaging format may differ (Tape & Box to Cut Tape)

The TAP104K050CRW qualifies as a direct substitute based on these criteria, offering enhanced voltage margin and improved tolerance while maintaining all critical physical and electrical parameters.

Engineering Selection Recommendations

The TAP104K050CRW serves as a qualified substitute for the TAP104M035CRS in applications where the design voltage specification permits operation at 50 V. Both components maintain Active product status from KYOCERA AVX and satisfy ROHS3 and REACH compliance requirements. The substitute part provides two distinct advantages: a 43% increase in voltage headroom (50 V versus 35 V) and improved capacitance tolerance (±10% versus ±20%), while maintaining identical physical footprint, ESR characteristics, and thermal operating range. Selection between these parts depends solely on circuit voltage requirements and tolerance specifications; no additional qualification is necessary when physical board layout and electrical performance margins are compatible with the 50 V rating.

Frequently Asked Questions (FAQ)

Q: Can TAP104K050CRW replace TAP104M035CRS in any application?

A: The TAP104K050CRW is electrically and mechanically compatible with TAP104M035CRS provided the circuit design operates at or below 50 V. The higher voltage rating and improved tolerance present no compatibility issues for circuits originally specified for 35 V operation.

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

A: The TAP104K050CRW offers a higher voltage rating (50 V versus 35 V) and tighter capacitance tolerance (±10% versus ±20%). All other electrical and physical parameters remain identical.

Q: Are the physical dimensions identical?

A: Yes. Both parts share the same radial package dimensions: 0.177" diameter (4.50 mm), 0.335" maximum seated height (8.50 mm), and 0.197" lead spacing (5.00 mm). PCB layout modifications are not required.

Q: Does packaging format affect substitution?

A: The TAP104M035CRS is supplied in Tape & Box format while TAP104K050CRW is supplied in Cut Tape format. This difference affects procurement and handling procedures but does not impact component performance or board-level compatibility.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both TAP104M035CRS and TAP104K050CRW are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.
