SR271E103MAR Equivalent & Substitute Parts

Part Overview

The SR271E103MAR is a 10000 pF ceramic capacitor rated at 100V with Z5U temperature coefficient, manufactured by KYOCERA AVX in the SkyCap® SR series. This radial through-hole component is designed for general-purpose applications and maintains active product status with full ROHS3 compliance. Substitute parts become necessary when the original part faces supply constraints, lead time requirements, or when design flexibility permits alternative form factors while maintaining electrical performance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution validity for the SR271E103MAR is determined by strict equivalence across the following parameters: capacitance value (10000 pF), tolerance (±20%), voltage rating (100V), temperature coefficient (Z5U), operating temperature range (10°C ~ 85°C), mounting type (through hole), and package configuration (radial). All identified substitute parts maintain these core electrical specifications. Physical dimensions and lead spacing vary across substitute options, requiring verification against PCB layout constraints. Lead style differences (formed versus straight) and height variations do not affect electrical performance but impact mechanical fit and assembly compatibility.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and ROHS3 compliance, ensuring regulatory alignment with the original SR271E103MAR. Selection between KYOCERA AVX and KEMET alternatives depends on PCB layout constraints and lead spacing requirements. The SR151E103MAR offers the most compact footprint with 0.100" lead spacing and minimal height, suitable for space-constrained designs. KEMET C-series options provide alternative lead spacing configurations: C315C103M1U5TA and C320C103M1U5TA feature 0.100" spacing for tight layouts, while C317C103M1U5TA and C322C103M1U5TA accommodate 0.200" spacing for standard pitch applications. Physical dimensions must be verified against PCB hole patterns and component placement requirements before final selection.

Frequently Asked Questions (FAQ)

Q: Can SR151E103MAR replace SR271E103MAR directly on the PCB? A: Electrical substitution is valid; however, the SR151E103MAR has different lead spacing (0.100" versus 0.300") and reduced height (0.150" versus 0.250"). PCB layout verification is required to confirm hole pattern compatibility.

Q: What is the difference between KYOCERA AVX and KEMET substitute options? A: Both manufacturers provide equivalent electrical specifications (10000 pF, ±20%, 100V, Z5U). KEMET GoldMax 300 Comm Z5U series offers multiple lead spacing and height configurations. Selection depends on available inventory and specific PCB layout requirements.

Q: Are formed leads and straight leads interchangeable? A: Both lead styles are mechanically compatible with through-hole mounting. Formed leads provide pre-bent geometry for specific spacing; straight leads require manual forming or insertion into pre-spaced holes. Lead style selection depends on assembly process and PCB design.

Q: Do all substitute parts meet the same compliance standards? A: Yes. All listed substitute parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 ECCN classification, matching the original SR271E103MAR specifications.

Q: Which substitute offers the closest physical match to SR271E103MAR? A: C322C103M1U5TA provides the closest dimensional alignment with 0.200" lead spacing and 0.260" maximum height, compared to the original 0.300" spacing and 0.250" height. However, exact PCB hole pattern verification remains necessary.
