SR201C153KAATR2- Equivalent & Substitute Parts

Part Overview

The SR201C153KAATR2- is a 0.015 µF ceramic capacitor rated at 100V with X7R temperature coefficient, manufactured by KYOCERA AVX in the SkyCap® SR series. This through-hole radial capacitor is designed for general-purpose applications requiring stable capacitance across the -55°C to 125°C operating temperature range. The part is currently active and in stock with 711 units available.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when alternative lead spacing or packaging configurations are required for specific PCB layouts, or when sourcing from multiple manufacturers is needed for supply chain resilience.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SR201C153KAATR2- is determined by the following critical parameters:

• Electrical Specifications: Capacitance value (0.015 µF), tolerance (±10%), voltage rating (100V), and temperature coefficient (X7R) must be identical
• Mounting Configuration: Through-hole radial mounting is required
• Temperature Performance: Operating range of -55°C to 125°C must be maintained
• Compliance: ROHS3 compliance and REACH unaffected status must be preserved

Physical dimensions and lead spacing variations are permissible within the radial through-hole category, as these affect PCB layout compatibility rather than electrical function. Lead style differences (straight vs. formed/kinked) represent acceptable mechanical variations for the same electrical performance.

Parameter Comparison

Engineering Selection Recommendations

SR211C153KAR (KYOCERA AVX): This part maintains identical electrical specifications and is from the same manufacturer series. The primary difference is lead spacing (0.200" vs. 0.100") and lead style (formed/kinked vs. straight). Selection is appropriate when PCB layout accommodates the wider lead spacing. Higher inventory availability (3156 units) supports supply continuity.

C320C153K1R5TA (KEMET): Electrically equivalent with identical lead spacing (0.100") and straight lead style matching the original part. The increased seated height (0.290" vs. 0.200") must be verified against PCB clearance requirements. This part offers the closest mechanical compatibility for direct substitution in existing designs.

C322C153K1R5TA (KEMET): Electrically equivalent with 0.200" lead spacing and formed leads. Seated height of 0.260" requires clearance verification. Selection is appropriate for designs with wider lead spacing requirements.

FK24X7R2A153KN000 (TDK Corporation): Electrically equivalent but carries "Not For New Designs" status. This part is suitable only for legacy system maintenance or repair applications where the original design already incorporates this component. Lead spacing of 0.197" (5.00mm) and formed/kinked leads require PCB layout compatibility assessment.

For new designs, prioritize parts with "Active" product status: SR211C153KAR, C320C153K1R5TA, or C322C153K1R5TA.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts interchangeably with the SR201C153KAATR2-?

A: All listed substitutes are electrically equivalent and meet the same electrical specifications (0.015 µF, ±10%, 100V, X7R, -55°C to 125°C). However, physical differences in lead spacing, lead style, and seated height require PCB layout verification before substitution. Direct pin-for-pin compatibility depends on your specific PCB design.

Q: What is the difference between straight leads and formed/kinked leads?

A: Straight leads maintain their original spacing from the component body. Formed or kinked leads are pre-bent to accommodate specific PCB hole patterns. The SR201C153KAATR2- has straight leads with 0.100" spacing, while SR211C153KAR and FK24X7R2A153KN000 have formed/kinked leads with 0.200" and 0.197" spacing respectively. Your PCB design determines which lead configuration is compatible.

Q: Why does the C320C153K1R5TA have a greater seated height than the original part?

A: Seated height variation (0.290" vs. 0.200") is a manufacturing difference between KEMET and KYOCERA AVX designs. This affects vertical clearance on the PCB. Verify that your PCB layout and component placement allow for the increased height before selecting this substitute.

Q: Should I use the FK24X7R2A153KN000 for new designs?

A: No. The FK24X7R2A153KN000 carries "Not For New Designs" status, indicating that TDK Corporation has discontinued this part for new applications. Use this part only for maintenance, repair, or legacy system support where the original design already incorporates it. For new designs, select from the active-status alternatives.

Q: Are all these parts RoHS3 compliant?

A: Yes. All listed parts, including the original SR201C153KAATR2-, are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What should I consider when selecting a substitute?

A: Verify three factors: (1) PCB hole spacing matches the lead spacing of your chosen substitute, (2) vertical clearance accommodates the seated height, and (3) the part's product status aligns with your application (active for new designs, any status for legacy support). Electrical specifications are identical across all options.
