SR385E105MAT Equivalent & Substitute Parts

Part Overview

The SR385E105MAT is a 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. Equivalent and substitute parts are identified based on matching electrical specifications (capacitance, voltage rating, tolerance, temperature coefficient) and compatible mechanical form factors for through-hole assembly.

Substitute Part Grouping Explanation

Substitution eligibility for the SR385E105MAT is determined by strict equivalence in the following parameters:

Electrical Match: Capacitance (1 µF), voltage rating (50V), tolerance (±20%), and temperature coefficient (Z5U) must be identical
Mechanical Compatibility: Through-hole radial package with lead spacing compatible with 0.375" (9.52mm) or smaller pitch applications
Compliance: ROHS3 compliance and REACH unaffected status maintained across all substitutes
Product Status: Active status ensures ongoing availability and support

Substitute parts are grouped by manufacturer and packaging configuration. Lead style and physical dimensions may vary within the constraints of radial through-hole assembly compatibility.

Engineering Selection Recommendations

All listed substitute parts maintain electrical and compliance equivalence to the SR385E105MAT. Selection between substitutes is determined by:

Packaging Requirements: Bulk packaging is suitable for high-volume manufacturing and assembly operations. Cut Tape (CT) packaging is appropriate for automated pick-and-place assembly systems.

Lead Spacing Compatibility: The SR385E105MAT features 0.375" (9.52mm) lead spacing. Substitutes with 0.200" (5.08mm) lead spacing require PCB redesign or mechanical adaptation. Direct mechanical substitution without board modification is limited to parts with matching lead spacing.

Manufacturer Selection: KYOCERA AVX SkyCap® SR series and KEMET GoldMax 300 Comm Z5U series are both active products with ROHS3 compliance and REACH unaffected status. Both manufacturers maintain equivalent electrical performance within specified tolerances.

Inventory Availability: KEMET C330C105M5U5TA and C330C105M5U5TA7301 offer the highest inventory levels (14108 and 10996 units respectively), supporting extended production runs without supply interruption.

Frequently Asked Questions (FAQ)

Q: Can SR215E105MARTR1 be used as a direct replacement for SR385E105MAT without PCB modification?

A: No. SR215E105MARTR1 has 0.200" (5.08mm) lead spacing compared to SR385E105MAT's 0.375" (9.52mm) spacing. Direct substitution requires PCB redesign or mechanical lead bending, which may compromise component reliability.

Q: Are KEMET C330C105M5U5TA and C330C105M5U5TA7301 electrically identical?

A: Yes. Both parts are electrically identical with 1 µF capacitance, 50V rating, ±20% tolerance, and Z5U temperature coefficient. The difference is packaging: C330C105M5U5TA is supplied in Bulk, while C330C105M5U5TA7301 is supplied in Cut Tape (CT).

Q: What is the significance of the Z5U temperature coefficient?

A: Z5U specifies the capacitance change over the operating temperature range of 10°C to 85°C. All listed parts maintain this specification, ensuring consistent performance across the defined temperature window.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. All substitute parts listed are ROHS3 compliant and REACH unaffected, matching the compliance status of the SR385E105MAT.

Q: Which substitute offers the best availability for high-volume production?

A: KEMET C330C105M5U5TA provides 14108 units in Bulk packaging, offering the highest inventory level for sustained production requirements.
