TAP104M050CRS Equivalent & Substitute Parts

Part Overview

The TAP104M050CRS is a 0.1 µF conformal coated tantalum capacitor rated for 50 V operation in radial through-hole configuration. 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. Substitute parts may be required due to inventory constraints, packaging format preferences, or tolerance specification adjustments while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TAP104M050CRS is determined by strict equivalence across the following critical parameters:

• Capacitance Value: Must be 0.1 µF (no deviation permitted)
• Voltage Rating: Must be 50 V or higher
• Type & Coating: Must be conformal coated tantalum
• ESR: Must be 26 Ohm
• Operating Temperature Range: Must support -55°C to 125°C
• Mounting Configuration: Must be through-hole radial with identical lead spacing (0.197" / 5.00mm)
• Physical Envelope: Must fit within 0.177" diameter and 0.335" maximum height
• Compliance: Must maintain ROHS3 compliance

The TAP104K050CRW qualifies as a direct substitute based on these parameters. The primary distinction is tolerance specification (±10% versus ±20%) and packaging format (Cut Tape versus Tape & Box), both of which are compatible with the original application requirements.

Parameter Comparison

Engineering Selection Recommendations

The TAP104K050CRW is a qualified substitute for the TAP104M050CRS based on electrical and mechanical equivalence. Both components are manufactured by KYOCERA AVX and maintain Active product status with full ROHS3 compliance. The substitute part offers improved tolerance specification (±10% versus ±20%), which represents an upgrade in precision without compromising circuit compatibility. Packaging format differs (Cut Tape versus Tape & Box), which may affect procurement and assembly workflows but does not impact electrical performance or board-level functionality. Selection between these parts should be based on inventory availability, packaging requirements for automated assembly processes, and tolerance specifications required by the application circuit design.

Frequently Asked Questions (FAQ)

Q: Can TAP104K050CRW replace TAP104M050CRS in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent. The substitute maintains identical capacitance (0.1 µF), voltage rating (50 V), ESR (26 Ohm), temperature range (-55°C to 125°C), and physical dimensions. The tighter tolerance (±10%) of the substitute is compatible with applications designed for the original ±20% tolerance specification.

Q: What is the difference between Tape & Box and Cut Tape packaging?

A: Tape & Box (TB) packaging provides capacitors on a reel with a protective box, suitable for manual handling and smaller production volumes. Cut Tape (CT) packaging provides individual components cut from the reel, optimized for high-speed automated assembly equipment. Both formats contain identical components; the difference is in delivery and handling format only.

Q: Are there any compliance or certification differences?

A: No. Both TAP104M050CRS and TAP104K050CRW maintain identical ROHS3 compliance status and are manufactured to the same KYOCERA AVX specifications. No additional testing or validation is required when substituting between these parts.

Q: Does the improved tolerance of TAP104K050CRW affect circuit performance?

A: The ±10% tolerance of the substitute is tighter than the ±20% tolerance of the original part. This represents improved precision and is fully compatible with circuit designs that accept the original ±20% specification. No circuit redesign or revalidation is necessary.

Q: Are the physical dimensions and lead spacing identical?

A: Yes. Both parts share identical radial through-hole configuration with 0.177" diameter (4.50mm), 0.335" maximum height (8.50mm), and 0.197" lead spacing (5.00mm). Direct board-level substitution is possible without PCB layout modifications.
