SR652C104KAATR1 Equivalent & Substitute Parts

Part Overview

The SR652C104KAATR1 is a 0.1 µF ±10% 200V X7R ceramic capacitor in radial configuration manufactured by KYOCERA AVX. This component is classified as Active product status and is designed for general-purpose applications requiring stable capacitance across the -55°C to 125°C operating temperature range. Substitute parts are necessary when the original part becomes unavailable, when higher voltage ratings are required for circuit margin, or when alternative packaging formats better suit assembly requirements.

Engineering Selection Recommendations

Direct Substitutes (200V Rating): C330C104K2R5TA and C333C104K2R5TA from KEMET are direct electrical equivalents to SR652C104KAATR1, both rated at 0.1 µF ±10% 200V X7R. Both are Active product status and ROHS3 compliant. C330C104K2R5TA features formed leads with 9.14mm seated height, while C333C104K2R5TA features formed leads with kinked configuration and 10.16mm seated height, matching the original part's lead style. Selection between these depends on available inventory and specific PCB layout requirements.

Upgrade Substitutes (Higher Voltage Ratings): SR307C104KARTR1 and SR657C104KARTR1 from KYOCERA AVX provide 500V rating in the same 0.1 µF ±10% X7R specification. Both are Active status. SR307C104KARTR1 uses straight leads with 9.14mm height, while SR657C104KARTR1 uses kinked formed leads with 10.16mm height matching the original. These upgrades provide increased voltage margin for circuits operating below 200V.

RDER72J104K4K1H03B and RDER72J104K4M1H03A from Murata Electronics offer 630V rating with Active product status. Both maintain 0.1 µF ±10% X7R specifications. RDER72J104K4K1H03B is available in bulk packaging, while RDER72J104K4M1H03A is supplied in cut tape format.

Legacy Alternatives (Not For New Designs): FK22X7R2J104KN000 and FK26X7R2E104KN000 from TDK Corporation are marked "Not For New Designs" and should be avoided for new circuit development. These parts are retained in this reference for legacy system maintenance only.

Frequently Asked Questions (FAQ)

Q: Can I use a 500V rated capacitor in place of the 200V SR652C104KAATR1? A: Yes. Higher voltage ratings are electrically compatible substitutes. The 500V rated SR307C104KARTR1 and SR657C104KARTR1 maintain identical capacitance (0.1 µF), tolerance (±10%), and temperature coefficient (X7R). The higher voltage rating provides additional circuit margin without affecting performance in 200V applications.

Q: What is the difference between SR307C104KAR and SR307C104KARTR1? A: Both are 500V rated KYOCERA AVX equivalents with identical electrical specifications. The primary difference is packaging: SR307C104KAR is supplied in bulk format, while SR307C104KARTR1 is supplied in cut tape (CT) format. Lead style also differs—SR307C104KAR features straight leads with 7.62mm height, while SR307C104KARTR1 features straight leads with 9.14mm height.

Q: Are KEMET C330C104K2R5TA and C333C104K2R5TA interchangeable? A: Both are direct 200V equivalents from KEMET with identical electrical ratings (0.1 µF ±10% X7R). The difference is lead configuration: C330C104K2R5TA has formed leads with 9.14mm seated height, while C333C104K2R5TA has kinked formed leads with 10.16mm seated height. Selection depends on PCB layout and lead spacing requirements.

Q: Why are FK22X7R2J104KN000 and FK26X7R2E104KN000 marked "Not For New Designs"? A: These TDK Corporation parts are legacy components retained for existing system support only. KYOCERA AVX and Murata Electronics alternatives with Active product status are recommended for new circuit designs to ensure long-term availability and supply chain stability.

Q: What are the mechanical compatibility considerations when substituting parts? A: All listed substitutes maintain through-hole radial mounting with 0.200" (5.08mm) lead spacing. However, seated heights vary between 5.50mm and 10.16mm. Verify PCB clearance and component spacing before substitution. Lead style differences (straight versus kinked formed leads) may affect insertion force and board assembly processes.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All parts listed in this reference are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.
