Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECW-H16122JV is permissible with parts meeting the following criteria:

• Capacitance value: 1200 pF (exact match required)
• Tolerance: ±5% (exact match required)
• Dielectric material: Polypropylene (PP), Metallized (exact match required)
• Voltage rating - DC: Equal to or greater than 1600V
• Voltage rating - AC: Equal to or greater than 424V
• Mounting type: Through Hole (exact match required)
• Package / Case: Radial (exact match required)
• Lead spacing: 0.591" (15.00mm) (exact match required)
• Termination: PC Pins (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

The B32672L8122J000 qualifies as a direct substitute because it maintains identical capacitance, tolerance, dielectric material, mounting configuration, and lead spacing while providing higher voltage ratings (2000V DC, 700V AC) and an extended operating temperature range (-55°C ~ 110°C).

Parameter Comparison

Engineering Selection Recommendations

Both the ECW-H16122JV and B32672L8122J000 are active production parts with ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current applications. The B32672L8122J000 provides enhanced voltage margin (2000V DC versus 1600V DC) and extended low-temperature operating capability (-55°C versus -40°C), making it suitable for applications requiring higher transient voltage protection or operation in colder environments. The B32672L8122J000 exhibits a more compact radial profile (10.50mm seated height versus 15.00mm), which may provide advantages in space-constrained PCB layouts. Both parts maintain identical lead spacing (15.00mm), ensuring direct footprint compatibility. Selection between these parts should be based on specific application voltage stress levels, thermal environment requirements, and available PCB real estate.

Frequently Asked Questions (FAQ)

Q: Can the B32672L8122J000 be used as a direct replacement for the ECW-H16122JV?

A: Yes. Both parts share identical capacitance (1200 pF), tolerance (±5%), dielectric material (polypropylene metallized), mounting type (through hole radial), lead spacing (15.00mm), and termination (PC pins). The B32672L8122J000 exceeds the voltage and temperature specifications of the ECW-H16122JV, making it functionally compatible for any application designed for the original part.

Q: What are the physical differences between these two parts?

A: The primary physical difference is the radial body width and seated height. The ECW-H16122JV measures 0.276" W x 0.591" H (7.00mm x 15.00mm), while the B32672L8122J000 measures 0.197" W x 0.413" H (5.00mm x 10.50mm). Both maintain the same 18.00mm length and 15.00mm lead spacing. The B32672L8122J000 occupies less vertical and lateral space on the PCB.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry EAR99 ECCN classification. Regulatory status is equivalent between the two parts.

Q: What voltage margin does the B32672L8122J000 provide?

A: The B32672L8122J000 is rated for 2000V DC (700V AC) compared to the ECW-H16122JV's 1600V DC (424V AC), providing a 400V DC (276V AC) voltage margin. This additional margin may be beneficial in applications subject to transient overvoltage conditions.

Q: Can the ECW-H16122JV be used in place of the B32672L8122J000?

A: No. The ECW-H16122JV has lower voltage ratings (1600V DC versus 2000V DC) and a narrower operating temperature range (-40°C to 105°C versus -55°C to 110°C). Use of the ECW-H16122JV in an application designed for the B32672L8122J000 may result in inadequate voltage margin or thermal stress.
