ECW-U1H682JB5 Film Capacitor Equivalent & Substitute Parts

Part Overview

The ECW-U1H682JB5 is a 6800 pF film capacitor manufactured by Panasonic Electronic Components, rated for 50V DC operation with ±5% tolerance. This component features a polyester/polyethylene naphthalate (PEN) metallized-stacked dielectric in a 1206 (3216 metric) surface mount package, suitable for general-purpose applications across an operating temperature range of -55°C to 105°C.

The ECW-U1H682JB5 is classified as obsolete. Identifying equivalent substitute parts ensures design continuity and supply chain reliability for applications requiring this capacitance and voltage rating.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ECW-U1H682JB5 are qualified based on the following critical parameters:

• Capacitance Value: 6800 pF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage Rating - DC: 50V (minimum requirement; higher ratings are acceptable)
• Package / Case: 1206 (3216 Metric) (exact match required for PCB compatibility)
• Mounting Type: Surface Mount (exact match required)
• Termination: Solder Pads (exact match required)

The substitute parts identified—ECH-U1H682JB5 and ECH-U1H682JX5—meet all critical electrical and mechanical parameters. Both are manufactured by Panasonic Electronic Components and maintain the same capacitance, tolerance, voltage rating, package footprint, and mounting configuration. These parts are classified as active products, ensuring ongoing availability and supply chain support.

Parameter Comparison

Engineering Selection Recommendations

Both ECH-U1H682JB5 and ECH-U1H682JX5 are qualified substitutes for the obsolete ECW-U1H682JB5. Selection between the two substitute parts should be based on the following factors:

ECH-U1H682JB5: This part maintains identical physical dimensions (0.039" maximum seated height) to the original ECW-U1H682JB5, ensuring direct PCB compatibility without layout modifications. It is ROHS3 compliant, REACH unaffected, and carries MSL 1 (unlimited) moisture sensitivity rating. Product status is active with substantial inventory availability.

ECH-U1H682JX5: This part features a slightly increased maximum seated height of 0.043" (1.10mm) compared to the original 0.039" (1.00mm). This 0.10mm height difference may require PCB clearance verification in space-constrained applications. It is also ROHS3 compliant, REACH unaffected, and carries MSL 1 (unlimited) moisture sensitivity rating. Product status is active with substantial inventory availability.

Both substitute parts offer extended operating temperature range (-55°C to 125°C versus -55°C to 105°C) and are manufactured by the same supplier, ensuring consistent quality and performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can ECH-U1H682JB5 and ECH-U1H682JX5 be used interchangeably with ECW-U1H682JB5?

A: Both parts meet the critical electrical specifications (6800 pF capacitance, ±5% tolerance, 50V DC rating) and package footprint (1206/3216 metric). ECH-U1H682JB5 maintains identical height specifications. ECH-U1H682JX5 has a 0.10mm greater maximum seated height and requires clearance verification. Both are direct functional substitutes.

Q: What is the difference between the dielectric materials used?

A: The original ECW-U1H682JB5 uses polyester/polyethylene naphthalate (PEN) dielectric. The substitute parts ECH-U1H682JB5 and ECH-U1H682JX5 use polyphenylene sulfide (PPS) dielectric. Both materials are suitable for general-purpose film capacitor applications and maintain the specified electrical performance at the rated voltage and temperature ranges.

Q: Are there any compliance or certification differences?

A: Both substitute parts are ROHS3 compliant and REACH unaffected. The original ECW-U1H682JB5 product status is obsolete. The substitute parts are active products with ongoing manufacturer support and availability.

Q: What is the significance of the packaging format difference?

A: The original part does not specify packaging format. Both substitute parts are supplied in Tape & Reel (TR) format, which is standard for automated assembly processes and provides better handling and storage characteristics compared to bulk packaging.

Q: Does the extended operating temperature range of the substitutes affect compatibility?

A: The substitute parts operate from -55°C to 125°C, compared to the original -55°C to 105°C range. This extended upper temperature limit provides additional thermal margin and does not negatively impact compatibility. Applications operating within the original temperature range will function identically.

Q: What is MSL 1 (Unlimited) moisture sensitivity level?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. This is the least restrictive moisture sensitivity classification and simplifies inventory management and assembly processes.
