Substitute Part Grouping Explanation

Substitution eligibility for the ECW-HC3F242JD is determined by strict equivalence across the following critical parameters:

• Capacitance value: 2400 pF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage Rating - DC: 3000V minimum (equal or higher acceptable)
• Dielectric Material: Polypropylene (PP), Metallized (exact match required)
• Operating Temperature Range: -40°C ~ 105°C (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial (exact match required)
• Physical dimensions and lead spacing (exact match required)
• Termination type: PC Pins (exact match required)

The ECW-HC3F242J qualifies as a parametric equivalent based on identical electrical specifications, physical form factor, and material composition. The presence of an AC voltage rating (1060V) in the substitute part does not affect DC circuit compatibility and represents additional specification data.

Parameter Comparison

Engineering Selection Recommendations

Selection between these parts is based on availability and inventory status. The ECW-HC3F242J currently maintains higher inventory levels (2622 pcs) compared to the ECW-HC3F242JD (762 pcs), making it suitable for high-volume procurement scenarios. Both parts are functionally interchangeable within circuits designed for the specified electrical and thermal parameters.

Frequently Asked Questions (FAQ)

Q: Can ECW-HC3F242J be used as a direct replacement for ECW-HC3F242JD?

A: Yes. Both parts share identical electrical specifications (2400 pF, ±5%, 3000V DC), dielectric material (polypropylene metallized), physical dimensions, lead spacing, and termination type. They are functionally equivalent for through-hole PCB applications.

Q: What is the significance of the AC voltage rating on the ECW-HC3F242J?

A: The AC voltage rating (1060V) is supplementary specification data. It does not affect DC circuit operation and indicates the part's capability in AC applications. The DC rating of 3000V remains the primary specification for DC circuit design.

Q: Are the physical dimensions identical between both parts?

A: Yes. Both parts measure 1.016" L x 0.240" W (25.80mm x 6.10mm) with a maximum seated height of 0.429" (10.90mm) and lead spacing of 0.886" (22.50mm). They are mechanically interchangeable in radial through-hole PCB layouts.

Q: Do both parts meet the same compliance standards?

A: Yes. Both ECW-HC3F242JD and ECW-HC3F242J are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS coding (8532.25.0040).

Q: What determines substitution eligibility for this capacitor?

A: Substitution is based on exact matching of capacitance (2400 pF), tolerance (±5%), DC voltage rating (3000V minimum), dielectric material (polypropylene metallized), operating temperature range (-40°C to 105°C), mounting type (through hole), package style (radial), physical dimensions, lead spacing, and termination type (PC pins).
