SR217C103KAATR1 Equivalent & Substitute Parts

Part Overview

The SR217C103KAATR1 is a 10000 pF ±10% 500V 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 ROHS3 compliant and currently in active production status with 838 units in stock.

Equivalent and substitute parts are identified based on matching or exceeding the electrical specifications (capacitance, voltage rating, tolerance, and temperature coefficient) while maintaining mechanical compatibility with radial through-hole mounting and formed lead configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are classified into three categories based on electrical performance relative to the main part:

Direct Equivalent (Same Specifications): Parts matching all critical electrical parameters—10000 pF capacitance, ±10% tolerance, 500V voltage rating, and X7R temperature coefficient—with identical mechanical form factors and lead spacing.

Upgraded Performance (Higher Voltage Rating): Parts with 10000 pF capacitance, X7R temperature coefficient, and operating temperature range identical to the main part, but with higher voltage ratings (630V or 1000V). These parts are electrically superior and mechanically compatible, though some may have minor dimensional variations.

Dimensional Considerations: All substitute parts maintain radial through-hole mounting with formed leads and 0.200" (5.08mm) or 0.197" (5.00mm) lead spacing, ensuring PCB compatibility. Height and body dimensions vary slightly between manufacturers but remain within acceptable through-hole assembly tolerances.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Preferred for Pin-Compatible Designs): K103K20X7RL5TH5 (Vishay) and C323C103KCR5TA (KEMET) are direct electrical equivalents with matching 500V ratings and ±10% tolerance. Both are in active production with ROHS3 compliance. K103K20X7RL5TH5 has slightly reduced lead spacing (0.197" vs. 0.200"), which may require PCB layout verification. C323C103KCR5TA maintains identical lead spacing and body dimensions to the main part.

Upgraded Performance (Higher Voltage Margin): C322C103KDR5TA (KEMET, 1000V, ±10%) and RDER72J103K2M1H03A (Murata, 630V, ±10%) provide higher voltage ratings while maintaining identical capacitance and temperature coefficient. Both are in active production with ROHS3 compliance. These parts are suitable for applications requiring increased voltage headroom. RDER72J103K2M1H03A offers the highest inventory availability (105,780 units).

Legacy Consideration: FK26X7R2J103KN000 (TDK, 630V) is marked "Not For New Designs" and should be avoided for new product development despite meeting electrical specifications.

Frequently Asked Questions (FAQ)

Q: Can K103K20X7RL5TH5 be used as a direct replacement? A: Yes. It matches all electrical specifications (10000 pF, ±10%, 500V, X7R, -55°C to 125°C). The lead spacing is 0.197" instead of 0.200", which is a 0.003" difference. Verify PCB hole spacing accommodates this minor variation before assembly.

Q: What is the difference between C322C103JDR5TA and C322C103KDR5TA? A: Both are KEMET GoldMax 300 Comm X7R HV parts with 10000 pF, 1000V, and identical mechanical form. C322C103JDR5TA has ±5% tolerance, while C322C103KDR5TA has ±10% tolerance. Select based on circuit tolerance requirements.

Q: Why are some parts rated at 630V or 1000V instead of 500V? A: Higher voltage ratings provide increased safety margin in applications subject to voltage transients or overshoot conditions. These parts are electrically compatible with 500V circuits and occupy the same PCB footprint.

Q: Is RDER72J103K2M1H03A suitable for high-volume production? A: Yes. It is in active production status with the highest inventory availability (105,780 units) among all substitutes, ROHS3 compliant, and meets all electrical specifications. Lead spacing is 0.197" (5.00mm).

Q: Can FK26X7R2J103KN000 be used in new designs? A: No. TDK has designated this part "Not For New Designs." While it meets electrical specifications, it should not be selected for new product development due to potential future discontinuation.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the main part's environmental compliance status.
