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 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 and ROHS3 compliant.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when alternative packaging or lead configurations better suit specific PCB layouts, or when design revisions require components from different manufacturers while maintaining identical electrical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SR201C153KAATR2 is determined by strict equivalence in the following parameters:

Capacitance value: 0.015 µF (exact match required)
Tolerance: ±10% (exact match required)
Voltage rating: 100V (exact match required)
Temperature coefficient: X7R (exact match required)
Operating temperature range: -55°C to 125°C (exact match required)
Mounting type: Through Hole (exact match required)
Package type: Radial (exact match required)
Compliance: ROHS3 Compliant (exact match required)

Variations in lead spacing, lead style, physical dimensions, and height are permitted substitution parameters, as these affect PCB layout compatibility but do not alter electrical performance. Packaging format (tape/reel versus bulk) does not affect electrical equivalence.

Engineering Selection Recommendations

All listed substitute parts meet the core electrical and compliance requirements for direct substitution with the SR201C153KAATR2. Selection among equivalents should be based on the following criteria:

For Active Product Status: SR211C153KAR, C320C153K1R5TA, and C322C153K1R5TA are all active products suitable for new designs. These three parts provide the highest assurance of long-term availability and consistent manufacturing quality.

For Lead Spacing Compatibility: If the PCB layout requires 0.100" (2.54mm) lead spacing matching the original SR201C153KAATR2, select C320C153K1R5TA from KEMET. If 0.200" (5.08mm) lead spacing is required, select either SR211C153KAR from KYOCERA AVX or C322C153K1R5TA from KEMET.

For Height Constraints: The SR201C153KAATR2 and SR211C153KAR both have a maximum seated height of 0.200" (5.08mm). The KEMET C320C153K1R5TA reaches 0.290" (7.36mm), and C322C153K1R5TA reaches 0.260" (6.60mm). Verify PCB clearance requirements before selection.

For Legacy Applications: FK24X7R2A153KN000 from TDK Corporation carries a "Not For New Designs" status and should be used only for replacement in existing equipment or when no other option is available.

For Inventory Availability: KEMET C320C153K1R5TA offers the highest current stock level at 3745 pieces, followed by KYOCERA AVX SR211C153KAR at 3156 pieces.

Frequently Asked Questions (FAQ)

Q: Can I substitute SR201C153KAATR2 with any of these parts without circuit redesign?

A: Yes, all listed parts are electrically equivalent. However, PCB layout modifications may be necessary due to differences in lead spacing and physical dimensions. Verify that the selected substitute's lead spacing and height fit your PCB design before implementation.

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

A: Straight leads maintain their original spacing and are inserted perpendicular to the PCB. Formed leads (kinked or standard formed) are pre-bent to accommodate different lead spacings. Both styles are mechanically and electrically equivalent; selection depends on PCB hole spacing and assembly equipment compatibility.

Q: Why is FK24X7R2A153KN000 marked "Not For New Designs"?

A: This designation indicates that TDK Corporation has discontinued active development and promotion of this part number. While electrically equivalent and currently in stock, it should not be selected for new product designs due to uncertain long-term availability. Use only for replacement or legacy applications.

Q: Are there any compliance or certification differences between manufacturers?

A: All listed parts are ROHS3 compliant, REACH unaffected, and carry the same ECCN and HTSUS classifications. No compliance or certification differences exist among the substitute options.

Q: How do I determine which lead spacing my PCB requires?

A: Measure the distance between the two holes on your PCB where the capacitor leads will be inserted. Common spacings for this capacitor value are 0.100" (2.54mm) and 0.200" (5.08mm). Match this measurement to the "Lead Spacing" parameter in the comparison table.
