SR275E104MAT Equivalent & Substitute Parts

Part Overview

The SR275E104MAT is a 0.1 µF ±20% 50V ceramic capacitor 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 ROHS3 compliance. Equivalent and substitute parts are identified based on matching electrical specifications (capacitance, voltage rating, tolerance, temperature coefficient) and compatible mechanical parameters (mounting type, package style, lead configuration).

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across electrical parameters and mechanical compatibility. All substitute parts must match the following criteria:

Mandatory Electrical Equivalence:

Capacitance: 0.1 µF
Voltage Rating: 50V
Tolerance: ±20%
Temperature Coefficient: Z5U
Operating Temperature: 10°C ~ 85°C

Mechanical Compatibility Criteria:

Mounting Type: Through Hole
Package / Case: Radial
Lead Style: Formed Leads (straight or kinked configurations acceptable)
RoHS Status: ROHS3 Compliant

Substitute parts are grouped into three categories: direct manufacturer alternatives (same manufacturer, different part number), manufacturer-recommended equivalents (alternative manufacturers with identical electrical specifications), and parametric equivalents (same electrical performance with minor dimensional variations).

Engineering Selection Recommendations

All listed substitute parts maintain ROHS3 compliance and active product status, ensuring regulatory alignment with the original SR275E104MAT component. Selection between KYOCERA AVX and KEMET alternatives depends on PCB layout constraints and lead spacing requirements.

KYOCERA AVX SR series substitutes (SR275E104MAR, SR275E104MAA, SR215E104MAA, SR215E104MART, SR215E104MARTR1) provide direct manufacturer continuity with identical electrical performance. The SR275 variants maintain the original 0.300" lead spacing, while SR215 variants reduce lead spacing to 0.200" and offer compact form factors suitable for space-constrained designs.

KEMET GoldMax 300 Comm Z5U series substitutes (C315C104M5U5TA, C315C104M5U5TA7303, C316C104M5U5TA, C317C104M5U5TA, C317C104M5U5TA7301) deliver equivalent electrical specifications with reduced physical dimensions. Lead spacing varies from 0.100" to 0.200", accommodating different PCB pitch requirements. The C315C series features straight leads, while C316C and C317C variants offer kinked or formed lead configurations.

Packaging format selection (Bulk versus Cut Tape) depends on assembly process requirements and inventory management practices. Cut Tape variants provide automated handling compatibility for high-volume production environments.

Frequently Asked Questions (FAQ)

Q: Can SR275E104MAR substitute for SR275E104MAT in all applications?

A: Yes. Both components share identical electrical specifications (0.1 µF, 50V, ±20%, Z5U) and lead spacing (0.300"). The width dimension differs by 0.010" (0.26mm), which does not affect electrical performance or standard PCB footprints.

Q: What is the primary difference between KYOCERA AVX and KEMET alternatives?

A: Electrical specifications are identical across both manufacturers. Physical dimensions differ significantly. KYOCERA AVX SR275 variants maintain larger form factors (0.260" L x 0.150-0.160" W), while KEMET C315C/C316C/C317C variants are more compact (0.150" L x 0.100" W). Lead spacing also varies: KYOCERA AVX SR275 uses 0.300" spacing, SR215 uses 0.200", and KEMET variants use 0.100" to 0.200" spacing.

Q: Are SR215 variants suitable replacements for SR275 in existing designs?

A: SR215 variants are electrically equivalent but feature reduced dimensions and different lead spacing (0.200" versus 0.300"). PCB layout compatibility must be verified before substitution, as the smaller footprint and closer lead spacing require design accommodation.

Q: What packaging options are available?

A: Bulk packaging is standard for most variants. Cut Tape (CT) packaging is available for SR215E104MARTR1, C315C104M5U5TA7303, and C317C104M5U5TA7301, providing automated handling for production environments.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All listed parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8532.24.0060, matching the original SR275E104MAT specifications.

Q: Which substitute offers the highest inventory availability?

A: C315C104M5U5TA7303 (KEMET, Cut Tape) provides the largest stock at 371,270 pieces, followed by C315C104M5U5TA (KEMET, Bulk) at 18,399 pieces.
