LDBCA1680JC5N0 Equivalent & Substitute Parts

Part Overview

The LDBCA1680JC5N0 is a 6800 pF film capacitor manufactured by KEMET, rated for 50V DC operation with ±5% tolerance. This surface mount component utilizes polyphenylene sulfide (PPS) metallized-stacked dielectric technology in a 1206 (3216 Metric) package. The part is Active status and RoHS3 compliant, designed for general-purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and design continuity when the primary part becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of film capacitors is determined by the following critical parameters: capacitance value, tolerance, voltage rating (DC), dielectric material composition, package footprint, and operating temperature range. All substitute parts listed maintain the 6800 pF capacitance value and ±5% tolerance specification. The primary substitution criterion is voltage rating compatibility: substitute parts must equal or exceed the 50V DC rating of the main part to ensure safe operation in the target application. Package footprint compatibility is essential for PCB layout; only parts in 1206 (3216 Metric) or mechanically equivalent packages are listed as direct substitutes. Dielectric material (PPS, metallized-stacked) and operating temperature range (-55°C ~ 125°C) are maintained across all substitute options. Compliance certifications (RoHS3, REACH Unaffected, EAR99) are consistent across all parts.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (1206 Package, 50V Rating):

ECH-U1H682JB5, ECH-U1H682JX5, and ECH-U1H682GX5 are direct substitutes for the LDBCA1680JC5N0. All three parts maintain the 1206 (3216 Metric) package footprint, 50V DC voltage rating, and -55°C to 125°C operating temperature range. These Panasonic parts are RoHS3 compliant and REACH Unaffected, matching the regulatory status of the main part. ECH-U1H682JB5 and ECH-U1H682JX5 maintain the ±5% tolerance specification. ECH-U1H682GX5 offers tighter ±2% tolerance, providing enhanced capacitance accuracy for applications requiring stricter component specifications. All three parts feature Moisture Sensitivity Level 1 (Unlimited), which provides superior moisture handling compared to the main part's MSL 3 rating.

Limited Substitute (0805 Package, 16V Rating):

ECH-U1C682JB5 is a Panasonic part with identical capacitance (6800 pF) and tolerance (±5%), but differs in two critical parameters: package footprint (0805 versus 1206) and voltage rating (16V versus 50V). This part is not suitable as a direct substitute for applications requiring the 50V DC rating or 1206 package footprint. Selection of this part requires PCB redesign and is only appropriate for applications with maximum voltage requirements of 16V or lower.

Compliance and Certification:

All substitute parts maintain Active product status and are manufactured to RoHS3 and REACH Unaffected standards, ensuring regulatory compliance equivalent to the main part. All parts carry EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can ECH-U1H682JB5, ECH-U1H682JX5, or ECH-U1H682GX5 be used as direct replacements for LDBCA1680JC5N0?

A: Yes. All three Panasonic parts are direct substitutes. They maintain the same 6800 pF capacitance, ±5% tolerance (except ECH-U1H682GX5 at ±2%), 50V DC voltage rating, 1206 package footprint, and -55°C to 125°C operating temperature range. Dimensional differences are minimal and within standard PCB assembly tolerances.

Q: What is the difference between ECH-U1H682JB5, ECH-U1H682JX5, and ECH-U1H682GX5?

A: The primary difference is tolerance specification. ECH-U1H682JB5 and ECH-U1H682JX5 maintain ±5% tolerance matching the main part. ECH-U1H682GX5 offers ±2% tolerance for applications requiring tighter capacitance accuracy. All three parts are electrically and mechanically compatible with the LDBCA1680JC5N0.

Q: Why is ECH-U1C682JB5 listed as a substitute if it has a different voltage rating and package?

A: ECH-U1C682JB5 is listed as a substitute only for applications where the 16V DC rating and 0805 package footprint are acceptable. It is not a direct substitute for the LDBCA1680JC5N0 in applications requiring 50V operation or 1206 package compatibility. Selection of this part requires design review and PCB modification.

Q: What is the significance of Moisture Sensitivity Level (MSL) differences?

A: The LDBCA1680JC5N0 has MSL 3 (168 Hours), while all Panasonic substitutes have MSL 1 (Unlimited). MSL 1 indicates superior moisture resistance and longer shelf life without baking requirements. This is an advantage when using Panasonic substitutes in humid storage or manufacturing environments.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (ECH-U1H682JB5, ECH-U1H682JX5, ECH-U1H682GX5, and ECH-U1C682JB5) are RoHS3 compliant and REACH Unaffected, matching the regulatory compliance of the main part.

Q: Can I use ECH-U1H682GX5 in place of LDBCA1680JC5N0 if my application requires ±5% tolerance?

A: No. ECH-U1H682GX5 has ±2% tolerance, which is tighter than the ±5% specification. While ±2% tolerance is more restrictive, it does not prevent use in applications designed for ±5% tolerance. However, if your design specifically requires ±5% tolerance as a maximum specification, ECH-U1H682GX5 exceeds this requirement and may introduce unnecessary cost. Use ECH-U1H682JB5 or ECH-U1H682JX5 for ±5% tolerance matching.

Q: What are the dimensional differences between the main part and substitute parts?

A: The LDBCA1680JC5N0 measures 0.130" L x 0.067" W (3.30mm x 1.70mm) with 0.043" maximum seated height. Panasonic 1206 substitutes measure 0.126" L x 0.063" W (3.20mm x 1.60mm) with seated heights of 0.039" to 0.043" depending on the specific part. These differences are within standard PCB assembly tolerances and do not affect mechanical compatibility. The 0805 part (ECH-U1C682JB5) is significantly smaller and requires PCB redesign.
