ECQ-P1H151JZ Equivalent & Substitute Parts

Part Overview

The ECQ-P1H151JZ is a 150 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 equivalent substitutes necessary for ongoing design requirements and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

The ECH-U1H151JX5 qualifies as a functional equivalent based on the following critical parameters:

Matching Parameters:

• Capacitance: 150 pF (identical)
• Tolerance: ±5% (identical)
• Voltage Rating (DC): 50V (identical)
• Dielectric Material: Film-based (both polypropylene and polyphenylene sulfide are film dielectrics suitable for equivalent performance)

Key Differences:

• Mounting Type: Surface Mount (0805) versus Through Hole (Radial)
• Operating Temperature: Extended range (-55°C ~ 125°C versus -40°C ~ 85°C)
• Dielectric Composition: Polyphenylene Sulfide (PPS) Metallized-Stacked versus Polypropylene (PP)
• Product Status: Active versus Obsolete

The ECH-U1H151JX5 maintains electrical equivalence in capacitance, tolerance, and voltage rating. However, the substitution requires PCB layout modification due to the change from radial through-hole to surface-mount 0805 package format.

Parameter Comparison

Engineering Selection Recommendations

The ECH-U1H151JX5 is electrically equivalent to the ECQ-P1H151JZ for applications requiring 150 pF capacitance at 50V DC with ±5% tolerance. The substitute part is currently in active production status with ROHS3 compliance certification, ensuring long-term availability and regulatory alignment.

Selection of the ECH-U1H151JX5 requires design modification to accommodate surface-mount 0805 package format in place of the original radial through-hole configuration. The extended operating temperature range (-55°C ~ 125°C) of the substitute provides additional thermal margin compared to the original part specification (-40°C ~ 85°C).

Frequently Asked Questions (FAQ)

Q: Can the ECH-U1H151JX5 be used as a direct replacement for the ECQ-P1H151JZ?

A: Electrical substitution is valid based on matching capacitance (150 pF), tolerance (±5%), and DC voltage rating (50V). However, physical substitution requires PCB redesign due to package format change from radial through-hole to surface-mount 0805.

Q: What are the critical parameters for determining substitution eligibility?

A: Capacitance value, tolerance, and DC voltage rating are the primary electrical parameters. The ECH-U1H151JX5 matches all three specifications. Mounting type and package format are secondary considerations that affect board-level implementation.

Q: Does the dielectric material difference affect performance?

A: Both polypropylene (PP) and polyphenylene sulfide (PPS) are film-based dielectrics. The PPS metallized-stacked construction in the substitute provides equivalent electrical performance for the specified application parameters.

Q: Is the substitute part compliant with current regulations?

A: The ECH-U1H151JX5 carries ROHS3 compliance certification. Both parts share the same ECCN classification (EAR99).

Q: What is the lead spacing consideration for the substitute?

A: The ECQ-P1H151JZ features 0.197" (5.00mm) lead spacing for radial through-hole mounting. The ECH-U1H151JX5 uses surface-mount solder pads with no discrete lead spacing specification, as it is designed for 0805 package footprint standards.
