SR305E105MAT Equivalent & Substitute Parts

Part Overview

The SR305E105MAT is a 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 is currently in active production 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).

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SR305E105MAT are grouped into three categories based on electrical and mechanical compatibility:

Direct Substitutes (Identical Electrical Specifications): Parts with matching capacitance (1 µF), voltage rating (50V), tolerance (±20%), and temperature coefficient (Z5U). These parts maintain the same operating temperature range (10°C ~ 85°C) and through-hole radial mounting configuration. Variations in physical dimensions and lead styles (straight vs. formed/kinked) are permitted within the radial package category, provided lead spacing remains 0.200" (5.08mm).

Packaging Variants: Direct electrical substitutes available in different packaging formats (Bulk vs. Cut Tape) are considered equivalent for component selection purposes.

Upgrade Substitute: The SR301E105MAR provides higher voltage rating (100V vs. 50V) while maintaining all other electrical parameters. This part is suitable for applications where increased voltage margin is required.

Cross-Manufacturer Equivalent: The KEMET C330C105M5U5TA and C330C105M5U5TA7301 provide identical electrical specifications and compatible mechanical parameters from an alternative manufacturer.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, consistent with the SR305E105MAT. Selection among direct substitutes should be based on:

Lead Configuration: Parts with straight leads (SR305E105MAT, SR305E105MAR, SR305E105MARTR1, C330C105M5U5TA, C330C105M5U5TA7301) are directly interchangeable in applications designed for straight-lead radial capacitors. Parts with formed/kinked leads (SR215E105MAA, SR215E105MAR, SR215E105MARTR1) are suitable for applications requiring pre-formed leads for automated insertion or space-constrained PCB layouts.

Packaging Format: Bulk packaging is standard for component procurement. Cut Tape (CT) packaging variants (SR305E105MARTR1, SR215E105MARTR1, C330C105M5U5TA7301) are available for high-volume automated assembly operations.

Voltage Upgrade: The SR301E105MAR (100V rating) is a suitable upgrade substitute when circuit design margins require higher voltage capability while maintaining all other electrical parameters.

Cross-Manufacturer Selection: KEMET C330C105M5U5TA and C330C105M5U5TA7301 provide equivalent electrical performance and are qualified alternatives when KYOCERA AVX parts are unavailable.

Frequently Asked Questions (FAQ)

Q: Can I use SR215E105MAA or SR215E105MAR in place of SR305E105MAT?

A: Yes. Both parts provide identical electrical specifications (1 µF, 50V, ±20%, Z5U). The primary difference is lead configuration: SR215 series features formed/kinked leads, while SR305E105MAT has straight leads. Compatibility depends on PCB design and insertion method. Verify lead spacing (0.200" for all parts) and physical clearance before substitution.

Q: What is the difference between Bulk and Cut Tape (CT) packaging?

A: Bulk packaging is supplied as loose components suitable for manual assembly or standard component feeders. Cut Tape (CT) packaging is pre-cut and taped for automated pick-and-place equipment. Electrical and mechanical specifications are identical; packaging selection depends on assembly process requirements.

Q: Is SR301E105MAR a direct substitute for SR305E105MAT?

A: SR301E105MAR is an upgrade substitute with higher voltage rating (100V vs. 50V). All other electrical parameters match (1 µF, ±20%, Z5U, 10°C ~ 85°C). This part is suitable for applications where increased voltage margin is beneficial. Verify circuit design requirements before substitution.

Q: Can I use KEMET C330C105M5U5TA instead of KYOCERA AVX SR305E105MAT?

A: Yes. The KEMET part provides identical electrical specifications and compatible mechanical parameters (1 µF, 50V, ±20%, Z5U, through-hole radial, 0.200" lead spacing, straight leads). Both manufacturers' parts are ROHS3 compliant. Cross-manufacturer substitution is valid when supply or cost considerations require it.

Q: Are all substitute parts rated for the same operating temperature range?

A: Yes. All listed substitute parts operate within the 10°C ~ 85°C temperature range with Z5U temperature coefficient, matching the SR305E105MAT specification.

Q: What does Z5U temperature coefficient mean?

A: Z5U is a ceramic capacitor temperature coefficient classification indicating capacitance change over the operating temperature range. All parts listed maintain this specification, ensuring consistent performance across the 10°C ~ 85°C operating window.
