SA205C104KAR Equivalent & Substitute Parts

Part Overview

The SA205C104KAR is a 0.1 µF ±10% 50V ceramic capacitor with X7R temperature coefficient in axial through-hole configuration, manufactured by KYOCERA AVX under the SpinGuard® SA series. This component is classified as Active product status with ROHS3 compliance and is suitable for general-purpose applications across the -55°C to 125°C operating temperature range. Equivalent and substitute parts are identified based on matching electrical specifications (capacitance, voltage rating, tolerance, temperature coefficient) and mechanical compatibility (axial through-hole mounting, lead style).

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: capacitance value (0.1 µF), tolerance (±10%), temperature coefficient (X7R), operating temperature range (-55°C to 125°C), mounting type (through hole), package type (axial), and lead style (straight). Voltage rating determines substitution category: parts rated at 50V are direct equivalents; parts rated at 100V are upgrades suitable for applications where higher voltage margin is acceptable. Physical dimensions (diameter and length) vary among substitutes but do not prevent functional substitution in through-hole applications where PCB layout permits component placement. All substitute parts maintain ROHS3 compliance and are manufactured by established component suppliers (KYOCERA AVX, KEMET, Vishay Beyschlag/Draloric/BC Components).

Parameter Comparison

Engineering Selection Recommendations

Direct equivalents at 50V rating include SA115C104KARC (KYOCERA AVX), A104K15X7RF5TAA (Vishay), C410C104K5R5TA (KEMET), C410C104K5R5TA7200 (KEMET), C420C104K5R5TA7200 (KEMET), C412C104K5R5TA7200 (KEMET), and C430C104K5R5TA (KEMET). These parts satisfy all electrical and mechanical requirements for direct substitution. Packaging format (Cut Tape vs. Bulk) should be selected based on procurement and assembly requirements; Cut Tape packaging is suitable for automated pick-and-place operations, while Bulk packaging is appropriate for manual assembly or high-volume reel applications.

Upgraded alternatives at 100V rating include A104K20X7RH5TAA (Vishay) and C410C104K1R5TA (KEMET). These parts provide higher voltage margin and are suitable for applications where circuit design permits voltage rating increase without affecting performance or cost constraints.

All substitute parts maintain ROHS3 compliance and operate across the identical temperature range (-55°C to 125°C). Selection among equivalent parts should prioritize availability, lead time, and cost factors. Physical dimension variations require verification against PCB layout constraints, particularly for components with larger diameter or length specifications.

Frequently Asked Questions (FAQ)

Q: Can SA115C104KARC replace SA205C104KAR directly? A: Yes. Both parts share identical electrical specifications (0.1 µF, ±10%, 50V, X7R, -55°C to 125°C). The primary difference is physical size: SA115C104KARC measures 0.120" diameter x 0.170" length, while SA205C104KAR measures 0.100" diameter x 0.260" length. Direct substitution is valid if PCB layout accommodates the different dimensions.

Q: What is the difference between 50V and 100V rated substitutes? A: Parts rated at 100V (A104K20X7RH5TAA, C410C104K1R5TA) provide higher voltage margin than the original 50V specification. These are upgrades suitable for applications where circuit design permits increased voltage rating. They maintain identical capacitance, tolerance, and temperature coefficient.

Q: Does packaging format (Cut Tape vs. Bulk) affect electrical performance? A: No. Packaging format affects only procurement, storage, and assembly logistics. Cut Tape packaging is optimized for automated assembly; Bulk packaging is used for manual assembly or high-volume reel applications. Electrical performance is identical.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance, matching the environmental and regulatory status of the original SA205C104KAR.

Q: Can I use C420C104K5R5TA7200 as a substitute if my PCB has limited space? A: C420C104K5R5TA7200 has identical diameter (0.100") to SA205C104KAR but identical length (0.260"). If space constraints exist, consider A104K15X7RF5TAA (0.098" x 0.150"), which is the most compact option among 50V equivalents.

Q: What determines whether a part is a direct equivalent versus an upgrade? A: Direct equivalents match all electrical parameters including voltage rating (50V). Upgrades have higher voltage ratings (100V) while maintaining identical capacitance, tolerance, and temperature coefficient. Upgrades are suitable only if circuit design permits the voltage increase.
