Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECQ-V1273JM3 is determined by the following critical parameters:

• Capacitance Value: Must be 0.027 µF
• Tolerance: Must be ±5%
• DC Voltage Rating: Must be rated for minimum 100V DC
• Dielectric Type: Polyester metallized construction
• Mounting Configuration: Through-hole radial package
• Lead Spacing: 0.197" (5.00mm) pitch for PCB compatibility
• Termination Style: PC pins for wave soldering or manual insertion

The substitute part 168273J100A-F meets all critical substitution criteria. It maintains identical capacitance, tolerance, voltage rating, and lead spacing while offering enhanced specifications in operating temperature range and active product status.

Parameter Comparison

Engineering Selection Recommendations

The 168273J100A-F from Cornell Dubilier Electronics is a direct functional equivalent for the obsolete ECQ-V1273JM3. Both components share identical electrical specifications: 0.027 µF capacitance, ±5% tolerance, 100V DC rating, and 5.00mm lead spacing. The substitute part offers extended operating temperature capability (-55°C to 125°C versus -40°C to 105°C) and maintains active product status, ensuring long-term availability and supply chain stability.

The 168273J100A-F carries ROHS3 compliance certification, meeting current environmental and regulatory requirements. Both components maintain MSL 1 classification, indicating no moisture sensitivity constraints during storage or handling.

Physical dimensions differ slightly: the substitute measures 0.283" L x 0.098" W (7.20mm x 2.50mm) compared to the original 0.295" L x 0.126" W (7.50mm x 3.20mm). This dimensional variance requires verification of PCB layout clearances and mechanical fit within the target assembly.
