ECJ-1VB1H682K Equivalent & Substitute Parts

Part Overview

The ECJ-1VB1H682K is a 6800 pF ceramic capacitor manufactured by Panasonic Electronic Components with X7R temperature coefficient, rated for 50V operation, and packaged in 0603 (1608 Metric) form factor. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The capacitor is designed for general-purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C.

Substitute Part Grouping Explanation

Substitution for the ECJ-1VB1H682K is determined by strict equivalence in the following parameters:

Capacitance value: 6800 pF (exact match required)
Temperature coefficient: X7R (ensures equivalent temperature stability)
Package / Case: 0603 (1608 Metric) (mechanical and electrical compatibility)
Mounting type: Surface Mount, MLCC (assembly process compatibility)
Moisture Sensitivity Level: 1 (Unlimited) (handling and storage compatibility)

Parts are grouped into three categories based on voltage rating and tolerance:

Category A - Direct Equivalents (50V, ±10%): Parts matching all parameters including voltage rating and tolerance. These provide direct functional replacement.

Category B - Tolerance Upgrade (50V, ±5%): Parts with tighter tolerance specification at the same voltage rating. These provide improved capacitance accuracy.

Category C - Voltage Upgrade (100V, ±10% or ±5%): Parts with higher voltage rating at the same or tighter tolerance. These provide additional voltage margin while maintaining or improving tolerance.

Engineering Selection Recommendations

For Direct Replacement (Obsolete Part Substitution):

Select from parts with matching 50V rating and ±10% tolerance: 0603B682K500CT (Walsin), C0603C682K5RAC7867 (KEMET), KGM15AR71H682KM or KGM15AR71H682KT (KYOCERA AVX), VJ0603Y682KXACW1BC or VJ0603Y682KXAPW1BC (Vishay Vitramon). All are active products with ROHS3 compliance and unlimited moisture sensitivity rating. 0603B682K500CT offers the highest inventory availability (189,725 pcs).

For Tolerance Upgrade:

06035C682JAT7A (KYOCERA AVX, ±5%, 50V) provides improved capacitance accuracy at the same voltage rating. Active product status with ROHS3 compliance.

For Voltage Margin Enhancement:

KGM15AR72A682KT (KYOCERA AVX, ±10%, 100V) or KGM15AR72A682JT (KYOCERA AVX, ±5%, 100V) provide higher voltage rating for applications requiring additional safety margin. Both are active products with ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can I use a 100V rated capacitor in place of the 50V ECJ-1VB1H682K?

A: Yes. A higher voltage rating is electrically compatible and provides additional voltage margin. The capacitor will function correctly in circuits designed for 50V operation. Physical dimensions and mounting remain identical within the 0603 package family.

Q: What is the difference between ±10% and ±5% tolerance parts?

A: Tolerance specifies the allowable deviation from the nominal 6800 pF capacitance value. ±10% allows deviation from 6120 pF to 7480 pF. ±5% allows deviation from 6460 pF to 7140 pF. Tighter tolerance (±5%) provides more precise capacitance but may have different pricing and availability.

Q: Are all substitute parts ROHS3 compliant?

A: All listed active substitute parts are ROHS3 compliant. The original ECJ-1VB1H682K does not specify RoHS status due to its obsolete classification.

Q: Does package size affect substitution?

A: All listed parts use the 0603 (1608 Metric) package. This ensures mechanical compatibility with existing PCB layouts and assembly equipment. Parts in different packages (0402, 0805, etc.) are not substitutes.

Q: What is Moisture Sensitivity Level 1?

A: MSL 1 indicates unlimited shelf life without moisture baking requirements. All listed parts have MSL 1 rating, matching the original part's moisture handling requirements.

Q: Can I substitute between different manufacturers?

A: Yes. All listed parts meet the same electrical specifications (6800 pF, X7R, 50V or higher, 0603 package). Manufacturer differences do not affect functional compatibility when specifications are equivalent.
