ECQ-P1H272GZ Equivalent & Substitute Parts

Part Overview

The ECQ-P1H272GZ is a 2700 pF film capacitor manufactured by Panasonic Electronic Components, rated for 50V DC operation with ±2% tolerance. This radial through-hole component utilizes polypropylene dielectric material and is designed for high-frequency and switching applications. The product is currently obsolete, making equivalent and substitute parts necessary for ongoing system maintenance, repairs, and legacy design support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECQ-P1H272GZ is determined by the following critical parameters:

• Capacitance Value: Must be 2700 pF (exact match required)
• Tolerance: ±2% or tighter tolerance acceptable
• Voltage Rating (DC): Minimum 50V; higher ratings acceptable
• Dielectric Material: Polypropylene (PP) or equivalent film material acceptable
• Mounting Type: Through-hole radial configuration required for direct PCB compatibility
• Lead Spacing: 0.197" (5.00mm) preferred for footprint compatibility
• Operating Temperature: Must support -40°C ~ 85°C minimum range

The substitute parts listed below meet the core electrical requirements (capacitance, tolerance, voltage rating) and maintain through-hole radial mounting. Variations in dielectric material, physical dimensions, and temperature range are noted where they differ from the original specification.

Parameter Comparison

Engineering Selection Recommendations

BFC241942702 (Vishay Beyschlag/Draloric/BC Components) is the primary substitute for direct PCB replacement. This part maintains through-hole radial mounting with identical 0.197" (5.00mm) lead spacing, ensuring mechanical compatibility without PCB layout modifications. The 400V DC rating provides voltage margin above the original 50V specification. Polypropylene dielectric material matches the original design intent for high-frequency and switching applications. The part is currently active in production and carries ROHS3 compliance certification.

QYX2A272JTP (Nichicon) provides an alternative through-hole radial option with 100V DC rating and matching lead spacing of 0.138" (4.60mm). However, this part is obsolete and features polyester dielectric material rather than polypropylene, which may affect performance in high-frequency applications. Tolerance is ±5% compared to the original ±2%, introducing greater capacitance variation.

ECH-U1H272GX5 (Panasonic) is not suitable for direct replacement due to surface-mount 0805 package configuration, which requires different PCB footprint and assembly process. This part is intended for new designs utilizing surface-mount technology rather than legacy through-hole systems.

Frequently Asked Questions (FAQ)

Q: Can ECH-U1H272GX5 replace ECQ-P1H272GZ on existing PCBs?

A: No. ECH-U1H272GX5 is a surface-mount 0805 component, while ECQ-P1H272GZ is through-hole radial. The packages are mechanically incompatible with existing PCB layouts designed for radial through-hole mounting.

Q: What is the primary difference between BFC241942702 and the original ECQ-P1H272GZ?

A: BFC241942702 has a 400V DC rating versus 50V DC on the original, and uses metallized polypropylene dielectric. Both maintain 2700 pF capacitance, ±2% tolerance, through-hole radial mounting, and 0.197" (5.00mm) lead spacing. The higher voltage rating provides additional safety margin in the circuit.

Q: Is QYX2A272JTP a viable substitute despite being obsolete?

A: QYX2A272JTP meets the core electrical requirements (2700 pF, through-hole radial, 100V DC rating) but has two limitations: ±5% tolerance versus ±2%, and polyester dielectric instead of polypropylene. For applications requiring tight capacitance tolerance or high-frequency performance, BFC241942702 is preferred.

Q: Does lead spacing affect substitution compatibility?

A: Yes. The original ECQ-P1H272GZ and BFC241942702 both use 0.197" (5.00mm) lead spacing, ensuring direct PCB compatibility. QYX2A272JTP uses 0.138" (4.60mm) spacing, requiring PCB layout verification or potential rework.

Q: Are all substitute parts RoHS compliant?

A: BFC241942702 and QYX2A272JTP carry ROHS3 compliance certification. ECH-U1H272GX5 is also ROHS3 compliant. Compliance status should be verified against your specific regulatory requirements.
