SR215C105KAR Equivalent & Substitute Parts

Part Overview

The SR215C105KAR is a 1 µF ±10% 50V ceramic capacitor with X7R temperature coefficient manufactured by KYOCERA AVX in the SkyCap® SR series. This radial through-hole component is designed for general-purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is currently active in production with 1918 units in stock.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design flexibility permits selection from multiple qualified manufacturers meeting identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SR215C105KAR is determined by strict equivalence across the following parameters:

• Capacitance value: 1 µF
• Tolerance: ±10%
• Voltage rating: 50V minimum
• Temperature coefficient: X7R
• Operating temperature range: -55°C to 125°C minimum
• Mounting type: Through Hole
• Package type: Radial with formed leads
• Lead spacing: 0.200" (5.08mm)
• Regulatory compliance: ROHS3 Compliant

Physical dimensions (length, width, height) may vary within industry-standard radial package tolerances without affecting electrical performance or PCB compatibility, provided lead spacing remains constant at 0.200" (5.08mm).

Parameter Comparison

Engineering Selection Recommendations

C333C105K5R5TA (KEMET GoldMax 300 Comm X7R) is the primary recommended substitute. This part maintains active product status, meets all electrical specifications, and provides equivalent performance with higher inventory availability (3722 units). The physical dimensions differ slightly from the original part but remain within standard radial package tolerances. Lead spacing of 0.200" (5.08mm) ensures direct PCB compatibility.

FK20X7R1H105KN000 (TDK FK Series) meets all electrical and mechanical requirements with the highest inventory level (45267 units). However, this part carries a "Not For New Designs" status, indicating the manufacturer has discontinued active development. This part remains suitable for replacement applications and legacy design support where supply continuity is prioritized. Lead spacing of 0.197" (5.00mm) represents a 0.003" (0.08mm) deviation from the original specification but remains within acceptable mechanical tolerances for standard through-hole PCB layouts.

Both substitute parts are ROHS3 compliant and maintain the required operating temperature range of -55°C to 125°C.

Frequently Asked Questions (FAQ)

Q: Can C333C105K5R5TA be used as a direct replacement for SR215C105KAR?

A: Yes. Both parts share identical electrical specifications (1 µF, ±10%, 50V, X7R, -55°C to 125°C) and lead spacing (0.200" / 5.08mm). Physical dimensions differ, but radial package variations are accommodated by standard PCB design tolerances.

Q: What is the significance of the "Not For New Designs" status on the TDK FK20X7R1H105KN000?

A: This designation indicates TDK has transitioned this part to end-of-life status and is not recommending it for new product designs. The part remains electrically and mechanically equivalent and is suitable for replacement, repair, and legacy system support where existing inventory is available.

Q: Does the 0.003" (0.08mm) lead spacing difference on the TDK part affect PCB compatibility?

A: No. Standard through-hole PCB design accommodates lead spacing variations within ±0.010" (0.25mm). The TDK part's 0.197" (5.00mm) spacing remains compatible with PCB holes designed for 0.200" (5.08mm) spacing.

Q: Are all three parts ROHS3 compliant?

A: Yes. SR215C105KAR, C333C105K5R5TA, and FK20X7R1H105KN000 are all ROHS3 compliant.

Q: What parameters must remain constant for substitution eligibility?

A: Capacitance (1 µF), tolerance (±10%), voltage rating (50V), temperature coefficient (X7R), operating temperature range (-55°C to 125°C), mounting type (through hole), package type (radial), and lead spacing (0.200" ± 0.010") must all remain equivalent.
