KGF15AR71H682KT Equivalent & Substitute Parts

Part Overview

The KGF15AR71H682KT is a 6800 pF ceramic capacitor manufactured by KYOCERA AVX in the FLEXITERM® series. This surface mount multilayer ceramic capacitor (MLCC) features X7R temperature coefficient, 50V rated voltage, and ±10% tolerance in 0603 (1608 Metric) package format. The part is active and in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified for applications requiring higher voltage ratings, improved tolerance specifications, or alternative temperature coefficient characteristics while maintaining the same capacitance value and package footprint.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Primary Compatibility Requirements:

Capacitance value: 6800 pF (exact match required)
Package / Case: 0603 (1608 Metric) (exact match required)
Mounting Type: Surface Mount, MLCC (exact match required)
Operating Temperature Range: -55°C ~ 125°C (exact match required)
RoHS Status: ROHS3 Compliant (exact match required)
Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Allowable Variations:

Voltage - Rated: Equal to or greater than 50V
Tolerance: ±5% or ±10%
Temperature Coefficient: X7R or C0G/NP0
Manufacturer: Different manufacturers permitted
Series designation: May vary

Substitute parts are grouped into two categories: upgrade parts with higher voltage ratings or improved tolerance, and direct equivalents with identical electrical specifications from alternative manufacturers.

Engineering Selection Recommendations

Direct Equivalents (Same Electrical Specifications):

C0603X682K5RAC7867 (KEMET) and CS0603KRX7R9BB682 (YAGEO) are direct substitutes with identical capacitance, tolerance, voltage rating, and temperature coefficient. Both are ROHS3 compliant with MSL 1 rating. Selection between these and the original part depends on supply chain availability and procurement preferences.

Upgrade Options (Higher Voltage Rating):

KGF15AR72A682JT and KGF15AR72A682KT (KYOCERA AVX) provide 100V rated voltage while maintaining 6800 pF capacitance and 0603 package. These upgrades are suitable for applications requiring higher voltage margin. KGF15AR72A682JT offers improved ±5% tolerance; KGF15AR72A682KT maintains ±10% tolerance. Both are ROHS3 compliant with MSL 1 rating.

Alternative Temperature Coefficient Options:

C0603X682J5GAC7867 and C0603X682K5GEC7867 (KEMET) feature C0G/NP0 temperature coefficient instead of X7R, with identical 50V rating and 6800 pF capacitance. C0G/NP0 provides superior temperature stability and lower ESL characteristics. Both are ROHS3 compliant with MSL 1 rating and soft termination features.

All substitute parts maintain the same 0603 (1608 Metric) package footprint, surface mount configuration, and operating temperature range (-55°C ~ 125°C) as the original part.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with higher voltage rating in place of the KGF15AR71H682KT? A: Yes. Parts rated for 100V (KGF15AR72A682JT, KGF15AR72A682KT) are electrically compatible substitutes. Higher voltage rating provides additional safety margin and does not degrade circuit performance in applications designed for 50V operation.

Q: What is the difference between X7R and C0G/NP0 temperature coefficients? A: X7R provides ±15% capacitance change across the operating temperature range (-55°C ~ 125°C). C0G/NP0 provides superior stability with ±0.3% per °C maximum change. C0G/NP0 is preferred for precision timing and filtering applications requiring minimal temperature drift.

Q: Are all substitute parts available in the same 0603 package? A: Yes. All listed substitute parts use the 0603 (1608 Metric) package with identical footprint dimensions (0.063" L x 0.031-0.032" W). Thickness varies slightly between manufacturers (0.034" to 0.037"), which is within standard PCB assembly tolerances.

Q: Do substitute parts have the same moisture sensitivity rating? A: Yes. All substitute parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity precautions are required during storage or handling.

Q: Which substitute offers the best tolerance specification? A: KGF15AR72A682JT and C0603X682J5GAC7867 both offer ±5% tolerance, compared to ±10% for the original part. ±5% tolerance provides tighter capacitance control for applications requiring precise component values.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, meeting the same environmental and regulatory requirements as the original KGF15AR71H682KT.
