KGM15ACG1E681JM Equivalent & Substitute Parts

Part Overview

The KGM15ACG1E681JM is a 680 pF ceramic capacitor manufactured by KYOCERA AVX, rated for 25V with C0G/NP0 temperature coefficient characteristics. This surface mount multilayer ceramic capacitor (MLCC) in 0603 (1608 Metric) package is designed for general purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is currently in active production status with ROHS3 compliance and MSL 1 rating, indicating unlimited moisture sensitivity protection. Substitute parts are identified when original inventory becomes unavailable or when design requirements necessitate alternative qualified sources while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitute parts for the KGM15ACG1E681JM are qualified based on strict parametric equivalence. All substitute parts must match the following critical parameters:

Capacitance value: 680 pF
Tolerance: ±5%
Voltage rating: 25V
Temperature coefficient: C0G or NP0
Operating temperature range: -55°C to 125°C
Package: 0603 (1608 Metric)
Mounting type: Surface Mount, MLCC
RoHS compliance: ROHS3 Compliant
MSL rating: 1 (Unlimited)

Substitutes are grouped into two categories: parametric equivalents from the same manufacturer (KYOCERA AVX) and direct equivalents from alternative qualified manufacturers (KEMET, YAGEO). All listed substitutes maintain identical electrical performance and physical compatibility with the original part.

Engineering Selection Recommendations

All listed substitute parts maintain active production status and full ROHS3 compliance, ensuring long-term availability and regulatory conformance. The KGM15ACG1E681JT from KYOCERA AVX represents the primary parametric equivalent, offering identical specifications with higher inventory availability (11,108 pcs vs. 892 pcs for the original part). This substitute is recommended when sourcing from the same manufacturer is preferred for supply chain consistency.

The KEMET C0603C681J3GAC7867 and YAGEO CC0603JRNPO8BN681 are direct cross-references from alternative qualified manufacturers. Both parts satisfy all electrical and mechanical requirements for direct substitution. The KEMET part features documented Low ESL characteristics, while the YAGEO part offers the highest inventory level (28,909 pcs), supporting extended production runs or high-volume applications.

All substitutes are REACH Unaffected and classified under ECCN EAR99, maintaining identical export compliance status with the original part. Selection among these options should be based on supply chain requirements, inventory availability, and established qualification protocols within your organization.

Frequently Asked Questions (FAQ)

Q: Can KGM15ACG1E681JT be used as a direct replacement for KGM15ACG1E681JM?

A: Yes. The KGM15ACG1E681JT is a parametric equivalent from the same manufacturer (KYOCERA AVX) with identical capacitance (680 pF), tolerance (±5%), voltage rating (25V), temperature coefficient (C0G/NP0), operating temperature range (-55°C to 125°C), and 0603 package specifications. The only difference is the packaging designation (JT vs. JM tape reel format), which does not affect electrical or mechanical compatibility.

Q: Are KEMET and YAGEO parts interchangeable with the KYOCERA AVX original?

A: Yes. The KEMET C0603C681J3GAC7867 and YAGEO CC0603JRNPO8BN681 are direct equivalents meeting all specified electrical parameters: 680 pF capacitance, ±5% tolerance, 25V rating, C0G/NP0 temperature coefficient, and -55°C to 125°C operating range. Physical dimensions are within tolerance for 0603 (1608 Metric) package specifications. All parts are ROHS3 compliant with MSL 1 rating.

Q: What are the key parameters that determine substitutability?

A: Substitutability is determined by: capacitance value (680 pF), tolerance (±5%), voltage rating (25V), temperature coefficient (C0G/NP0), operating temperature range (-55°C to 125°C), package type (0603/1608 Metric), and mounting method (Surface Mount MLCC). All listed substitutes match these parameters exactly.

Q: Does the slight difference in thickness between parts affect PCB assembly?

A: No. The thickness variation between parts (0.034" to 0.035" maximum) falls within standard 0603 package tolerance specifications and does not impact PCB assembly, reflow soldering, or component placement processes.

Q: Are all substitute parts currently in active production?

A: Yes. All listed substitute parts maintain active production status with ROHS3 compliance and unlimited moisture sensitivity protection (MSL 1), ensuring continued availability and regulatory conformance.
