ECW-U1H562JB5 Equivalent & Substitute Parts

Part Overview

The ECW-U1H562JB5 is a 5600 pF film capacitor rated at 50V DC, manufactured by Panasonic Electronic Components in the ECW-U(B) series. This component features a polyester and polyethylene naphthalate (PEN) metallized-stacked dielectric, housed in a 1206 (3216 Metric) surface mount package. The part is currently obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for ongoing production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECW-U1H562JB5 is determined by the following critical parameters:

• Capacitance Value: Must be 5600 pF
• Tolerance: Must be ±5%
• Voltage Rating - DC: Must be 50V or higher
• Package / Case: Must be 1206 (3216 Metric)
• Mounting Type: Must be Surface Mount
• Termination: Must be Solder Pads

The substitute parts identified (ECH-U1H562JB5 and ECH-U1H562JX5) meet all critical electrical parameters. Both are active Panasonic components with identical capacitance, tolerance, and voltage ratings. The dielectric material differs (Polyphenylene Sulfide (PPS) instead of Polyester/PEN), and the operating temperature range extends to 125°C. Physical dimensions remain compatible within the 1206 package specification, with maximum seated heights of 1.00mm and 1.10mm respectively, both acceptable for standard 1206 footprints.

Parameter Comparison

Engineering Selection Recommendations

Both ECH-U1H562JB5 and ECH-U1H562JX5 are suitable direct substitutes for the obsolete ECW-U1H562JB5. Selection between the two substitute options is based on the following factors:

ECH-U1H562JB5 is the primary recommendation. It maintains identical physical dimensions (0.039" maximum seated height) and is part of the ECH-U(B) series, providing the closest series alignment to the original ECW-U(B) component. This part is ROHS3 compliant with MSL rating of 1 (Unlimited), indicating superior moisture handling characteristics suitable for standard manufacturing environments.

ECH-U1H562JX5 is an alternative option within the ECH-U(X) series. It features a marginally increased maximum seated height of 0.043" (1.10mm), which remains within standard 1206 footprint tolerances but may require PCB layout verification in space-constrained applications. This part is also ROHS3 compliant with MSL rating of 1 (Unlimited).

Both substitutes offer extended operating temperature range (-55°C ~ 125°C) compared to the original part (-55°C ~ 105°C), providing enhanced thermal performance. Both are currently in active production with substantial inventory availability.

Frequently Asked Questions (FAQ)

Q: Can ECH-U1H562JB5 or ECH-U1H562JX5 be used as direct replacements for ECW-U1H562JB5?

A: Yes. Both parts meet all critical electrical specifications: 5600 pF capacitance, ±5% tolerance, 50V DC rating, and 1206 surface mount package with solder pad termination. Physical dimensions are compatible with standard 1206 PCB footprints.

Q: What is the difference between the two substitute parts?

A: The primary difference is the maximum seated height. ECH-U1H562JB5 maintains 0.039" (1.00mm), identical to the original part. ECH-U1H562JX5 has a maximum seated height of 0.043" (1.10mm). Both are within 1206 package specifications. The parts belong to different Panasonic series (ECH-U(B) versus ECH-U(X)).

Q: Why does the dielectric material differ between the original and substitute parts?

A: The original ECW-U1H562JB5 uses Polyester/PEN dielectric, while the substitutes use Polyphenylene Sulfide (PPS). Both dielectric materials are suitable for general-purpose film capacitor applications at the specified voltage and capacitance ratings. The PPS dielectric in the substitutes provides extended operating temperature capability (125°C versus 105°C).

Q: Are there any compliance or certification differences?

A: The substitute parts are ROHS3 compliant with MSL rating of 1 (Unlimited), indicating compliance with current environmental and moisture sensitivity standards. Both are supplied in Tape & Reel (TR) packaging, standard for automated assembly processes.

Q: Which substitute should be selected for new designs?

A: ECH-U1H562JB5 is recommended for new designs due to identical physical dimensions and series alignment. ECH-U1H562JX5 is acceptable if PCB layout accommodates the 0.043" maximum seated height.

Q: Are these parts suitable for high-temperature applications?

A: Both substitute parts operate to 125°C, exceeding the original part's 105°C rating. Application suitability depends on specific circuit requirements and thermal management design.
