ECQ-P1H271JZ Equivalent & Substitute Parts

Part Overview

The ECQ-P1H271JZ is a 270 pF film capacitor manufactured by Panasonic Electronic Components, rated for 50V DC operation with ±5% tolerance. This radial through-hole component utilizes polypropylene (PP) dielectric material and is designed for high-frequency and switching applications. The part is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system support, maintenance, and new design implementations where legacy specifications must be maintained.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECQ-P1H271JZ is determined by strict equivalence in the following parameters:

• Capacitance Value: 270 pF (exact match required)
• Tolerance: ±5% (acceptable range for functional equivalence)
• Voltage Rating (DC): 50V minimum (equal or higher ratings are acceptable)
• Dielectric Material: Film-based dielectric (polypropylene or equivalent film technology)

The ECH-U1H271JX5 meets these core electrical requirements. However, this substitute introduces a significant change in mounting technology: it transitions from through-hole radial to surface-mount 0805 (2012 Metric) format. This substitution is valid only when circuit board redesign or adapter solutions are feasible.

Parameter Comparison

Engineering Selection Recommendations

The ECH-U1H271JX5 is the designated substitute for the ECQ-P1H271JZ based on electrical parameter equivalence. Selection of this substitute requires evaluation of the following factors:

Product Status: The ECQ-P1H271JZ is obsolete with limited inventory availability (990 pcs). The ECH-U1H271JX5 is active with robust inventory (7036 pcs), ensuring long-term supply chain continuity.

Compliance & Certifications: The ECH-U1H271JX5 carries ROHS3 compliance and REACH Unaffected status, meeting modern regulatory requirements. Both parts share EAR99 ECCN classification and identical HTSUS codes (8532.25.0010).

Packaging & Mounting Transition: Direct board-level substitution is not possible without circuit redesign. The through-hole radial format of the main part must be replaced with surface-mount assembly processes or adapter solutions compatible with 0805 (2012 Metric) footprints.

Dielectric Material Difference: While both parts are film-based capacitors, the substitute uses polyphenylene sulfide (PPS) metallized-stacked construction versus polypropylene (PP) in the original. This material change expands the operating temperature range (-55°C ~ 125°C versus -40°C ~ 85°C) and maintains electrical performance within specified tolerances.

Frequently Asked Questions (FAQ)

Q: Can the ECH-U1H271JX5 be used as a direct drop-in replacement for the ECQ-P1H271JZ?

A: No. The ECH-U1H271JX5 uses surface-mount 0805 (2012 Metric) packaging, while the ECQ-P1H271JZ is a through-hole radial component. Direct substitution requires circuit board redesign or mechanical adapter solutions.

Q: Are the electrical specifications identical between these two parts?

A: The capacitance (270 pF), tolerance (±5%), and DC voltage rating (50V) are identical. The dielectric materials differ: polypropylene (PP) in the main part versus polyphenylene sulfide (PPS) metallized-stacked in the substitute. Both materials are film-based and suitable for high-frequency applications.

Q: What is the operating temperature difference, and does it affect compatibility?

A: The ECQ-P1H271JZ operates from -40°C to 85°C, while the ECH-U1H271JX5 operates from -55°C to 125°C. The substitute provides an extended temperature range, making it suitable for applications requiring broader thermal performance. For circuits designed within the original temperature range, both parts are functionally equivalent.

Q: Does the ECH-U1H271JX5 meet current regulatory standards?

A: Yes. The ECH-U1H271JX5 is ROHS3 compliant and REACH Unaffected. The obsolete ECQ-P1H271JZ does not carry these certifications, making the substitute preferable for new designs and systems requiring modern compliance documentation.

Q: What is the size difference between these components?

A: The ECQ-P1H271JZ measures 0.335" L x 0.177" W (8.50mm x 4.50mm) with a maximum seated height of 0.492" (12.50mm). The ECH-U1H271JX5 measures 0.079" L x 0.049" W (2.00mm x 1.25mm) with a maximum seated height of 0.043" (1.10mm). The substitute is significantly smaller, typical of surface-mount 0805 components.

Q: Are both parts suitable for high-frequency and switching applications?

A: The ECQ-P1H271JZ is explicitly rated for high-frequency and switching applications. The ECH-U1H271JX5 is classified for general-purpose use. For applications requiring high-frequency performance, circuit-level validation is necessary to confirm the substitute's suitability in the specific switching or high-frequency context.
