SR152C331KAATR1 Equivalent & Substitute Parts

Part Overview

The SR152C331KAATR1 is a 330 pF ceramic capacitor rated at 200V with X7R temperature coefficient, manufactured by KYOCERA AVX under the SkyCap® SR series. This through-hole radial component is designed for general-purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications.

Substitute Part Grouping Explanation

Substitution eligibility for the SR152C331KAATR1 is determined by strict equivalence in the following parameters: capacitance value (330 pF), tolerance (±10%), voltage rating (200V), temperature coefficient (X7R), operating temperature range (-55°C to 125°C), mounting type (through hole), and package type (radial). Lead spacing and lead style variations are permitted where mechanical fit allows board-level accommodation. All substitute parts must maintain ROHS3 compliance and EAR99 export classification.

Engineering Selection Recommendations

All listed substitute parts maintain ROHS3 compliance and EAR99 export classification consistent with the original SR152C331KAATR1. Selection among active alternatives depends on board layout constraints and lead spacing requirements.

For direct mechanical and electrical replacement with minimal PCB modification, SR152C331KAATR2 provides identical lead spacing (0.100"), straight lead style, and equivalent height profile while maintaining active product status from KYOCERA AVX.

For applications where lead spacing flexibility exists, SR072C331KAATR1 and SR072C331KAAAP2 offer reduced height (0.100" seated) with kinked formed leads, suitable for compact layouts. SR122C331KAATR1 accommodates 0.200" lead spacing with formed leads for wider pitch board designs.

Cross-manufacturer alternatives from KEMET (C315C331K2R5TA, C317C331K2R5TA) and Vishay (K331K15X7RK5TL2, K331K15X7RK5TH5) provide parametric equivalence with variations in lead spacing and height. C315C331K2R5TA maintains 0.100" lead spacing for direct footprint compatibility. C317C331K2R5TA and K331K15X7RK5TH5 require 0.200" and 0.197" lead spacing respectively.

Frequently Asked Questions (FAQ)

Q: Can SR152C331KAATR2 directly replace SR152C331KAATR1 on existing PCBs?

A: Yes. Both parts share identical lead spacing (0.100"), straight lead style, and equivalent height (0.150" maximum seated height). Electrical and thermal characteristics are identical. The primary difference is product status: SR152C331KAATR1 is obsolete while SR152C331KAATR2 is active.

Q: What is the difference between straight and formed leads?

A: Straight leads maintain their original orientation and require precise hole spacing matching the 0.100" or 0.200" specification. Formed leads (kinked or pre-bent) are shaped for specific lead spacing and may accommodate minor PCB variations. Formed leads typically result in lower seated height.

Q: Can I use C317C331K2R5TA as a substitute if my PCB has 0.100" lead spacing?

A: No. C317C331K2R5TA requires 0.200" lead spacing. Using this part on a 0.100" spaced footprint will result in mechanical misalignment. Use C315C331K2R5TA instead, which maintains 0.100" lead spacing.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the original SR152C331KAATR1.

Q: What is the significance of the X7R temperature coefficient?

A: X7R indicates capacitance variation of ±15% across the full operating temperature range (-55°C to 125°C). All listed substitutes maintain this specification, ensuring stable performance across temperature extremes.

Q: Can I mix different manufacturers in the same assembly?

A: Yes. All substitutes meet identical electrical specifications (330 pF, ±10%, 200V, X7R, -55°C to 125°C). Mechanical compatibility depends on PCB footprint design and lead spacing requirements.
