ECQ-V1273JM2 Equivalent & Substitute Parts

Part Overview

The ECQ-V1273JM2 is a 0.027 µF film capacitor rated for 100V DC operation with ±5% tolerance, manufactured by Panasonic Electronic Components. This polyester metallized stacked radial capacitor is designed for general-purpose applications in through-hole configurations. The part is currently obsolete, making equivalent substitutes necessary for ongoing production, maintenance, and repair applications. Identifying compatible alternatives ensures design continuity and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECQ-V1273JM2 is determined by the following critical parameters:

• Capacitance Value: Must be 0.027 µF (exact match required)
• Tolerance: ±5% (standard tolerance for film capacitors)
• Voltage Rating - DC: Minimum 100V (equal or higher acceptable)
• Dielectric Material: Polyester, Metallized (functional equivalent)
• Mounting Type: Through Hole (mechanical compatibility)
• Package / Case: Radial (form factor requirement)
• Lead Spacing: 0.197" (5.00mm) (PCB layout compatibility)
• Termination: PC Pins (soldering compatibility)

The substitute part 168273J100A-F from Cornell Dubilier Electronics meets all critical substitution criteria. It maintains identical capacitance, tolerance, voltage rating, dielectric material, mounting type, package style, lead spacing, and termination type. Physical dimensions are comparable within acceptable manufacturing tolerances for radial film capacitors.

Engineering Selection Recommendations

The 168273J100A-F from Cornell Dubilier Electronics is a direct functional substitute for the obsolete ECQ-V1273JM2. Selection is based on the following factors:

• Product Status: The substitute is active and in production, ensuring long-term availability and supply chain stability compared to the obsolete original part.
• Electrical Specifications: All critical electrical parameters match exactly, including capacitance, tolerance, and DC voltage rating.
• Compliance: The substitute meets ROHS3 compliance requirements, providing regulatory advantage for new designs and manufacturing environments with stricter environmental standards.
• Environmental Ratings: The substitute offers an extended operating temperature range (-55°C ~ 125°C versus -40°C ~ 105°C), providing additional thermal margin for demanding applications.
• Physical Compatibility: Lead spacing, termination type, and radial package configuration are identical, enabling direct PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can the 168273J100A-F be used as a direct replacement for the ECQ-V1273JM2 without PCB modifications?

A: Yes. Both parts share identical lead spacing (0.197" / 5.00mm), radial package configuration, and PC pin termination. No PCB layout changes are required for substitution.

Q: What is the significance of the wider operating temperature range in the substitute part?

A: The 168273J100A-F operates from -55°C to 125°C, compared to the original part's -40°C to 105°C range. This provides additional thermal margin for applications exposed to extreme environmental conditions, though both parts are suitable for standard industrial temperature ranges.

Q: Are there any compliance differences between the original and substitute parts?

A: The substitute part is ROHS3 compliant, whereas the original part's RoHS status is not specified. Both parts are REACH unaffected. For applications requiring RoHS compliance, the substitute provides regulatory assurance.

Q: How do the physical dimensions compare?

A: The substitute part (7.20mm L x 2.50mm W, 6.50mm height) is slightly more compact than the original (7.50mm L x 3.20mm W, 8.00mm height). Both fit standard radial capacitor footprints with 5.00mm lead spacing, though the substitute occupies less board space.

Q: Is the AC voltage rating relevant for this application?

A: The original part does not specify an AC voltage rating. The substitute is rated for 63V AC. For DC-only applications, the AC rating is not a limiting factor. For applications requiring AC operation, verify that 63V AC meets circuit requirements.

Q: What inventory status should be considered for procurement?

A: Both parts show adequate stock availability (874 pcs for original, 878 pcs for substitute). However, the substitute's active product status ensures continued availability, while the original's obsolete status presents long-term supply risk.
