ECJ-2VC1H680J Equivalent & Substitute Parts

Part Overview

The ECJ-2VC1H680J is a 68 pF ±5% 50V ceramic capacitor in C0G/NP0 temperature coefficient, manufactured by Panasonic Electronic Components in 0805 (2012 Metric) surface mount package. This part is classified as obsolete, making equivalent substitutes necessary for ongoing production and design requirements. Substitute parts must maintain identical electrical specifications and mechanical compatibility to ensure direct board-level replacement without design modification.

Key Parameters

Parameter	Value
Capacitance	68 pF
Tolerance	±5%
Voltage Rating	50V
Temperature Coefficient	C0G, NP0
Operating Temperature Range	-55°C to 125°C
Package / Case	0805 (2012 Metric)
Mounting Type	Surface Mount, MLCC
Moisture Sensitivity Level	MSL 1 (Unlimited)

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters:

Capacitance value: 68 pF (exact match required)
Tolerance: ±5% (exact match required)
Voltage rating: 50V minimum (equal or higher acceptable)
Temperature coefficient: C0G/NP0 (exact match required)
Operating temperature range: -55°C to 125°C (exact match required)
Package: 0805 (2012 Metric) (exact match required)
Mounting type: Surface Mount, MLCC (exact match required)
Moisture sensitivity: MSL 1 (exact match required)

Direct substitutes maintain all parameters identically. Upgrade substitutes provide enhanced specifications (higher voltage rating or tighter tolerance) while maintaining all other parameters, suitable for applications where improved performance margins are beneficial.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a higher voltage rating?

A: Yes. C0805C680F1GAC7800 (100V rating) is electrically compatible with ECJ-2VC1H680J (50V rating) and provides additional voltage margin. The higher voltage rating does not degrade performance in 50V applications.

Q: What is the difference between direct substitutes and upgrade substitutes?

A: Direct substitutes maintain all electrical and mechanical parameters identically to the original part. Upgrade substitutes enhance one or more specifications (voltage rating or tolerance) while maintaining all other parameters. Both are compatible with the original design.

Q: Are YAGEO AC series parts suitable for automotive applications?

A: Yes. AC0805JPNPO9BN680 and AC0805JRNPO9BN680 carry AEC-Q200 qualification, indicating suitability for automotive applications. These parts are direct electrical equivalents with automotive-grade reliability ratings.

Q: Does thickness variation affect PCB assembly compatibility?

A: Thickness variation within the 0805 package specification (0.028" to 0.037" maximum) does not affect standard PCB assembly processes. All listed substitutes are compatible with standard pick-and-place and reflow equipment.

Q: Which substitute has the best inventory availability?

A: KGM21BCG1H680JT (KYOCERA AVX) offers the highest inventory with 28,290 units in stock, providing supply chain security for high-volume production.

Q: Is RoHS compliance required for my application?

A: Most active substitutes are ROHS3 compliant. Only 08055A680JAJ2A is RoHS non-compliant. Verify your application requirements before selecting this part.
