Substitute Part Grouping Explanation

Substitution of the TAP104K035CRW is permissible with the TAP104K050CRW based on the following criteria:

Matching Parameters (Substitution Basis):

• Capacitance: 0.1 µF (identical)
• Tolerance: ±10% (identical)
• Type: Conformal Coated (identical)
• ESR: 26 Ohm (identical)
• Operating Temperature: -55°C ~ 125°C (identical)
• Mounting Type: Through Hole (identical)
• Package / Case: Radial (identical)
• Physical Dimensions: 0.177" Dia (4.50mm), Height 0.335" (8.50mm), Lead Spacing 0.197" (5.00mm) (identical)
• Manufacturer Size Code: A (identical)
• RoHS Status: ROHS3 Compliant (identical)

Differing Parameter (Upgrade Characteristic):

• Voltage - Rated: 50 V (substitute) vs. 35 V (original)

The TAP104K050CRW operates at a higher voltage rating while maintaining all other electrical and mechanical specifications. This represents a voltage-uprated equivalent suitable for applications where the original 35 V rating is adequate but higher voltage margin is desired.

Parameter Comparison

Engineering Selection Recommendations

The TAP104K050CRW qualifies as a direct substitute for the TAP104K035CRW in applications where the circuit voltage does not exceed 35 V. Both components maintain identical electrical performance characteristics, physical form factor, and regulatory compliance status (ROHS3 Compliant, REACH Unaffected, EAR99 classification). The higher voltage rating of the substitute part introduces no functional degradation and provides additional voltage margin for circuit protection. Packaging format differs (Cut Tape vs. Tape & Reel), which may affect procurement and assembly workflows but does not impact electrical or mechanical compatibility. Both parts are Active status products from the same manufacturer, ensuring consistent quality and reliability standards.

Frequently Asked Questions (FAQ)

Q: Can TAP104K050CRW replace TAP104K035CRW in my circuit?

A: Yes, provided your circuit voltage does not exceed 35 V. The substitute part maintains identical capacitance, tolerance, ESR, temperature range, and physical dimensions. The 50 V rating is a voltage upgrade that does not affect performance in lower-voltage applications.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both components share identical radial package dimensions: 0.177" diameter (4.50mm), 0.335" maximum seated height (8.50mm), and 0.197" lead spacing (5.00mm). Direct PCB footprint compatibility is confirmed.

Q: What is the difference in packaging between these parts?

A: The original TAP104K035CRW is supplied in Tape & Reel (TR) format, while the substitute TAP104K050CRW is supplied in Cut Tape (CT) format. This affects bulk ordering and automated assembly processes but does not impact the component itself.

Q: Do both parts meet the same compliance standards?

A: Yes. Both TAP104K035CRW and TAP104K050CRW are ROHS3 Compliant, REACH Unaffected, and classified as EAR99 for export control purposes. Regulatory compliance is equivalent.

Q: Is there a performance difference between 35 V and 50 V rated parts?

A: No performance difference exists in circuits operating below 35 V. The 50 V rating provides additional safety margin and voltage headroom. ESR, capacitance, tolerance, and temperature characteristics remain identical.

Q: Which part should I select if inventory is a concern?

A: The TAP104K050CRW has significantly higher inventory availability (3844 units vs. 719 units). If voltage margin is acceptable for your application, the substitute part offers better supply chain availability.
