SR225E104MAT Equivalent & Substitute Parts

Part Overview

The SR225E104MAT is a 0.1 µF ±20% 50V ceramic capacitor with Z5U temperature coefficient manufactured by KYOCERA AVX in the SkyCap® SR series. This through-hole radial component is designed for general-purpose applications and maintains active product status. Equivalent and substitute parts are identified based on matching electrical specifications (capacitance, voltage rating, tolerance, temperature coefficient) and compatible mechanical parameters (mounting type, lead configuration, package dimensions).

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence in electrical parameters: capacitance value (0.1 µF), tolerance (±20%), voltage rating (50V), and temperature coefficient (Z5U). All substitute parts maintain the same operating temperature range (10°C ~ 85°C) and through-hole radial mounting configuration.

Mechanical variations in lead spacing, lead style (formed vs. kinked), height, and package format (bulk vs. cut tape) do not affect electrical substitutability but may impact PCB layout compatibility and assembly processes. Parts are grouped by manufacturer and lead configuration to facilitate selection based on specific assembly requirements.

Engineering Selection Recommendations

All listed substitute parts maintain electrical equivalence to the SR225E104MAT through identical capacitance, voltage rating, tolerance, and temperature coefficient specifications. All parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Selection between KYOCERA AVX and KEMET alternatives depends on PCB layout constraints determined by lead spacing and lead style. The SR225E104MAR offers the closest mechanical match with identical lead spacing (0.250") and formed leads, differing only in reduced height. KYOCERA AVX SR215 series parts feature reduced lead spacing (0.200") and kinked leads, suitable for compact layouts. KEMET GoldMax 300 Comm Z5U series parts provide additional options with varying lead spacing and configurations.

Packaging format selection (bulk vs. cut tape) is determined by assembly process requirements and does not affect electrical performance.

Frequently Asked Questions (FAQ)

Q: Can SR225E104MAR be used as a direct replacement for SR225E104MAT?

A: Yes. Both parts are KYOCERA AVX SkyCap® SR series components with identical electrical specifications (0.1 µF, ±20%, 50V, Z5U). The primary difference is seated height (0.200" vs. 0.300"), which may affect PCB clearance but does not impact electrical function.

Q: What is the difference between KYOCERA AVX and KEMET substitute options?

A: Both manufacturers provide 0.1 µF ±20% 50V Z5U ceramic capacitors meeting the same electrical requirements. Differences lie in lead spacing, lead style, and physical dimensions. KYOCERA AVX parts maintain closer dimensional alignment to the original SR225E104MAT, while KEMET options offer alternative lead configurations for different PCB layouts.

Q: Are KEMET C315C104M5U5TA and C317C104M5U5TA interchangeable?

A: Both are electrically equivalent (0.1 µF, ±20%, 50V, Z5U) but differ mechanically. C315C features 0.100" lead spacing with straight leads, while C317C features 0.200" lead spacing with formed leads. PCB hole spacing determines which is compatible with your design.

Q: What does the "7303" and "7301" suffix indicate?

A: These suffixes denote cut tape (CT) packaging format with specific tape reel configurations. The electrical and mechanical specifications remain identical to their bulk counterparts (C315C104M5U5TA7303 vs. C315C104M5U5TA; C317C104M5U5TA7301 vs. C317C104M5U5TA).

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed parts carry ROHS3 compliance certification and are REACH unaffected, meeting current environmental and regulatory standards.

Q: Which substitute offers the highest inventory availability?

A: C315C104M5U5TA7303 (KEMET, cut tape format) provides the largest inventory at 371,270 pieces, followed by C315C104M5U5TA (KEMET, bulk) at 18,399 pieces.
