SR155C332MAT Equivalent & Substitute Parts

Part Overview

The SR155C332MAT is a 3300 pF ceramic capacitor manufactured by KYOCERA AVX, rated for 50V with X7R temperature coefficient and ±20% tolerance. This radial through-hole component is part of the SkyCap® SR series and maintains active product status. Alternative equivalent parts may be required due to inventory constraints, design optimization for higher voltage ratings, or tolerance improvements in circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SR155C332MAT is determined by the following critical parameters:

• Capacitance Value: Must be 3300 pF (exact match required)
• Temperature Coefficient: Must be X7R (ensures stable capacitance across operating temperature range)
• Mounting Type: Must be Through Hole with Radial package configuration
• Operating Temperature Range: Must support -55°C to 125°C minimum
• RoHS Compliance: Must maintain ROHS3 Compliant status

Voltage rating and tolerance may vary within acceptable design margins. Lead spacing and physical dimensions must accommodate existing PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

SR151C332KAR provides an upgrade path with improved tolerance (±10% versus ±20%) and higher voltage rating (100V versus 50V). Both components are manufactured by KYOCERA AVX within the SkyCap® SR series, maintaining design consistency. This substitute is suitable for applications requiring tighter capacitance tolerance or operating in circuits with higher voltage margins.

K332K15X7RF53L2 maintains the original 50V voltage rating with improved ±10% tolerance. Manufactured by Vishay Beyschlag/Draloric/BC Components under the Mono-Kap™ K series, this substitute offers higher inventory availability (17,117 pcs). Physical dimensions differ slightly (0.157" L x 0.102" W versus 0.150" L x 0.100" W), and lead spacing is 0.098" (2.50mm) versus 0.100" (2.54mm). PCB layout verification is required before implementation.

All substitute parts maintain ROHS3 compliance and support the full -55°C to 125°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can SR151C332KAR replace SR155C332MAT in any application?

A: Yes, SR151C332KAR is a direct functional substitute. The higher 100V rating provides additional design margin, and the ±10% tolerance improves circuit performance. No circuit modifications are required.

Q: What is the primary difference between the two KYOCERA AVX substitutes?

A: SR151C332KAR is rated for 100V with ±10% tolerance, while the main part SR155C332MAT is rated for 50V with ±20% tolerance. Both share identical capacitance, temperature coefficient, and lead spacing.

Q: Is K332K15X7RF53L2 compatible with existing PCB layouts designed for SR155C332MAT?

A: Lead spacing differs by 0.002" (0.50mm), and physical dimensions vary slightly. PCB layout verification is required to confirm mechanical fit before substitution.

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

A: Yes. SR151C332KAR, K332K15X7RF53L2, and SR155C332MAT are all ROHS3 Compliant and REACH Unaffected.

Q: Which substitute offers the best tolerance performance?

A: Both SR151C332KAR and K332K15X7RF53L2 provide ±10% tolerance, compared to ±20% for the main part. Selection depends on voltage rating requirements and PCB layout constraints.
