SR595C683KAATR1 Equivalent & Substitute Parts

Part Overview

The SR595C683KAATR1 is a 0.068 µF ±10% 50V ceramic capacitor with X7R temperature coefficient manufactured by KYOCERA AVX in the SkyCap® SR series. This radial through-hole component is designed for general-purpose applications and operates across -55°C to 125°C. The part is currently active and ROHS3 compliant.

Substitute parts become necessary when the original SR595C683KAATR1 is unavailable, when alternative packaging formats are required, or when design flexibility allows for equivalent electrical performance from other manufacturers. All substitute parts listed maintain identical electrical specifications while offering variations in physical dimensions and lead configurations.

Substitute Part Grouping Explanation

Substitution validity for the SR595C683KAATR1 is determined by strict equivalence in the following electrical parameters:

Capacitance: 0.068 µF (exact match required)
Tolerance: ±10% (exact match required)
Voltage Rating: 50V (exact match required)
Temperature Coefficient: X7R (exact match required)
Operating Temperature: -55°C to 125°C (exact match required)
Mounting Type: Through Hole (exact match required)
Package Type: Radial (exact match required)

All substitute parts listed meet these criteria. Physical dimensions, lead spacing, and lead style may vary within the radial through-hole category. Packaging format (Tape & Reel vs. Bulk vs. Cut Tape) does not affect electrical equivalence but may impact procurement and handling procedures.

Engineering Selection Recommendations

All substitute parts listed are electrically equivalent to the SR595C683KAATR1 and maintain full ROHS3 compliance and REACH unaffected status.

For new designs, prioritize parts with Active product status: C320C683K5R5TA, C322C683K5R5TA, K683K15X7RF5TL2, RDER71H683K0K1H03B, and RDER71H683K0P1H03B. These parts are actively supported by their respective manufacturers.

The FK28X7R1H683KN000 from TDK Corporation carries a "Not For New Designs" status and should be used only for legacy system maintenance or replacement applications where the original part is no longer available.

Physical dimension variations exist among substitutes. The SR595C683KAATR1 features formed leads with kinked style and 0.200" lead spacing. Alternative configurations include straight leads with 0.100" or 0.098" spacing (C320C683K5R5TA, K683K15X7RF5TL2, RDER71H683K0P1H03B) and formed leads with 0.197" or 0.098" spacing (FK28X7R1H683KN000, RDER71H683K0K1H03B). PCB layout compatibility must be verified before substitution.

Frequently Asked Questions (FAQ)

Q: Are all listed parts electrically interchangeable with the SR595C683KAATR1?

A: Yes. All substitute parts maintain identical capacitance (0.068 µF), tolerance (±10%), voltage rating (50V), temperature coefficient (X7R), and operating temperature range (-55°C to 125°C). Electrical performance is equivalent across all listed parts.

Q: What are the key differences between substitute parts?

A: Differences exist in physical dimensions, lead spacing, and lead style. The SR595C683KAATR1 uses formed leads with kinked style and 0.200" spacing. Substitutes vary: C320C683K5R5TA and K683K15X7RF5TL2 feature straight leads with reduced spacing (0.100" and 0.098" respectively), while FK28X7R1H683KN000 and RDER71H683K0K1H03B offer formed leads with different spacing configurations. PCB hole patterns must accommodate the selected lead spacing.

Q: Can I use FK28X7R1H683KN000 in new designs?

A: No. FK28X7R1H683KN000 carries "Not For New Designs" status. Use this part only for replacement or legacy system maintenance. For new designs, select from parts with Active status.

Q: Does packaging format affect substitution compatibility?

A: Packaging format (Tape & Reel, Bulk, Cut Tape) does not affect electrical equivalence or PCB performance. Format selection depends on procurement volume, handling procedures, and assembly line requirements. All formats deliver identical component specifications.

Q: Which substitute offers the highest inventory availability?

A: K683K15X7RF5TL2 from Vishay Beyschlag/Draloric/BC Components shows 11,679 pieces in stock, significantly higher than other alternatives. This part is available in Cut Tape packaging.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, matching the compliance status of the SR595C683KAATR1.
