Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECW-H8273HL is determined by the following critical parameters:

• Capacitance Value: Must be 0.027 µF (±3% tolerance acceptable)
• Voltage Rating - DC: Must be rated for 800V DC minimum
• Dielectric Material: Must be Polypropylene (PP), Metallized
• Mounting Type: Must be Through Hole
• Package / Case: Must be Radial configuration
• Termination: Must use PC Pins

The ECW-H8273HA meets all substitution criteria as a member of the same ECW-H base product family with identical electrical specifications and compatible mechanical configuration.

Parameter Comparison

Engineering Selection Recommendations

The ECW-H8273HA is the designated substitute for the obsolete ECW-H8273HL. Both components share identical electrical specifications: 0.027 µF capacitance, ±3% tolerance, and 800V DC voltage rating with polypropylene metallized dielectric construction.

The ECW-H8273HA offers the advantage of active product status, ensuring continued availability and supply chain reliability. The substitute maintains full electrical compatibility for high-frequency and switching applications within the specified operating temperature range.

Physical dimensions differ between the two variants. The ECW-H8273HA features a more compact footprint (15.70mm x 7.60mm versus 23.00mm x 5.00mm) with reduced lead spacing (12.50mm versus 20.00mm). PCB layout modifications may be required to accommodate these dimensional changes.

The ECW-H8273HA carries ROHS3 compliance certification, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Frequently Asked Questions (FAQ)

Q: Can the ECW-H8273HA directly replace the ECW-H8273HL without circuit modification?

A: Electrical substitution is direct. Both components have identical capacitance (0.027 µF), tolerance (±3%), and DC voltage rating (800V). However, physical dimensions and lead spacing differ, requiring PCB layout verification and potential trace routing adjustments.

Q: What is the significance of the different operating temperature ranges?

A: The ECW-H8273HL operates to 110°C maximum, while the ECW-H8273HA operates to 105°C maximum. For applications operating near or above 105°C, thermal performance must be evaluated against actual circuit requirements.

Q: Does the AC voltage rating difference affect substitution suitability?

A: The ECW-H8273HA specifies 283V AC rating, while the ECW-H8273HL does not specify an AC rating. For DC-only applications, this difference is not relevant. For circuits with AC or mixed AC/DC operation, the AC voltage specification must be evaluated against circuit requirements.

Q: Are there any compliance or certification differences between these parts?

A: The ECW-H8273HA is ROHS3 compliant and REACH unaffected. The ECW-H8273HL specifications do not include these certifications. For applications subject to environmental or regulatory compliance requirements, the ECW-H8273HA meets current standards.

Q: What packaging differences exist between these components?

A: The ECW-H8273HL is supplied in standard packaging, while the ECW-H8273HA is supplied in bulk packaging. Both use identical radial through-hole configuration with PC pin termination.
