SR215C154MART Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The SR215C154MART is a 0.15 µF ±20% 50V X7R ceramic capacitor manufactured by KYOCERA AVX in radial through-hole configuration. This component is classified as Active product status and is suitable 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 alternative packaging formats are required, or when design specifications allow for tighter tolerance or higher voltage ratings.

Substitute Part Grouping Explanation

Substitution for the SR215C154MART is determined by the following critical parameters:

Capacitance Value: Must be 0.15 µF (exact match required)
Voltage Rating: Minimum 50V (equal or higher voltage ratings are acceptable)
Temperature Coefficient: X7R (ensures equivalent temperature stability)
Mounting Type: Through Hole (radial configuration)
Lead Spacing: 0.200" (5.08mm) or compatible spacing for PCB layout
Tolerance: ±20% or tighter (±10% substitutes provide improved accuracy)
Compliance: ROHS3 Compliant, REACH Unaffected, EAR99 classification

Substitute parts are grouped into two categories: direct equivalents (same voltage rating and tolerance class) and upgraded alternatives (higher voltage rating or tighter tolerance).

Engineering Selection Recommendations

Direct Equivalents (50V Rating, Active Status):

C322C154K5R5TA (KEMET) and K154K20X7RF53H5 (Vishay) are the primary direct substitutes. Both maintain the 50V voltage rating, X7R temperature coefficient, and through-hole radial configuration. C322C154K5R5TA offers a lower seated height (0.260" vs 0.300"), which may provide advantages in space-constrained layouts. K154K20X7RF53H5 maintains a height profile closer to the original part. Both are ROHS3 compliant and carry Active product status, making them suitable for new designs.

Compact Alternatives (50V Rating, Active Status):

RDER71H154K1K1H03B and RDER71H154K1M1H03A (Murata Electronics) provide the most compact form factor with a maximum seated height of 0.197". These parts are suitable for applications where vertical space is limited. RDER71H154K1M1H03A is available in Cut Tape packaging, offering flexibility for automated assembly processes. Both maintain Active product status and full compliance.

Higher Voltage Alternative (100V Rating):

FK26X7R2A154KN000 (TDK Corporation) provides a 100V voltage rating while maintaining the 0.15 µF capacitance and X7R temperature coefficient. This part is classified as Not For New Designs and carries a lead spacing of 0.197" (5.00mm), requiring PCB layout verification before substitution.

Legacy Parts (Not For New Designs):

FK28X7R1H154KR000 (TDK Corporation) is classified as Not For New Designs and should be avoided for new circuit implementations, though it remains available for legacy system maintenance.

Frequently Asked Questions (FAQ)

Q: Can I substitute the SR215C154MART with a part having ±10% tolerance instead of ±20%?

A: Yes. Parts with ±10% tolerance (C322C154K5R5TA, K154K20X7RF53H5, RDER71H154K1K1H03B, RDER71H154K1M1H03A) are direct substitutes. The tighter tolerance provides improved capacitance accuracy and is backward-compatible with designs specified for ±20% tolerance.

Q: Are there physical size differences I need to consider?

A: Yes. Lead spacing varies between 0.197" (5.00mm) and 0.200" (5.08mm). Verify PCB hole spacing before substitution. Seated heights range from 0.197" to 0.300", which may affect clearance in confined spaces. Murata parts (RDER series) offer the most compact profile.

Q: Can I use the FK26X7R2A154KN000 (100V) as a substitute?

A: Yes, from an electrical standpoint. The higher voltage rating provides additional safety margin. However, this part is classified as Not For New Designs and has different lead spacing (0.197" vs 0.200"), requiring PCB layout verification.

Q: What is the difference between RDER71H154K1K1H03B and RDER71H154K1M1H03A?

A: Both parts are electrically identical with the same capacitance, tolerance, voltage, and temperature coefficient. The primary difference is packaging: RDER71H154K1K1H03B is supplied in Bulk, while RDER71H154K1M1H03A is supplied in Cut Tape (CT) format, which is optimized for automated pick-and-place assembly.

Q: Which substitute offers the best compatibility with the original part?

A: C322C154K5R5TA (KEMET) and K154K20X7RF53H5 (Vishay) provide the closest compatibility. Both maintain 50V rating, Active product status, and lead spacing within acceptable tolerance. C322C154K5R5TA has a slightly lower profile, while K154K20X7RF53H5 maintains a height closer to the original.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant, REACH Unaffected, and classified as EAR99, matching the compliance profile of the SR215C154MART.
