SHO-501 Common Mode Choke Equivalent & Substitute Parts

Part Overview

The SHO-501 is a 2-line common mode choke (CMC) designed for power line filtering applications. This through-hole component features 17.5 µH inductance at 100 kHz with an 800 mA maximum current rating and 105 mOhm DC resistance. The part is Active in product status and ROHS3 compliant, making it suitable for current industrial and commercial applications requiring electromagnetic interference suppression in dual-conductor power circuits.

Substitute parts are identified when equivalent electrical and mechanical parameters allow direct functional replacement within the same application context, maintaining circuit performance and physical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SHO-501 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Manufacturer: KEMET
• Series: SHO
• Filter Type: Power Line
• Number of Lines: 2
• Current Rating (Max): 800 mA
• Voltage Rating - DC: 50 V
• Mounting Type: Through Hole
• Package / Case: Vertical, No Base, 4 PC Pin
• Operating Temperature Range: -25°C to 80°C
• RoHS Status: ROHS3 Compliant

Allowable Variation Parameters:

• Inductance @ Frequency: Variation permitted based on application filtering requirements
• DC Resistance (Max): Variation permitted within thermal and power dissipation limits
• Size / Dimension: Variation permitted if through-hole pin configuration remains compatible

The SHO-402 qualifies as a parametric equivalent because it maintains all mandatory matching parameters while varying inductance (99 µH @ 100 kHz) and DC resistance (120 mOhm), with a larger physical footprint (0.295" Dia / 7.50 mm).

Parameter Comparison

Engineering Selection Recommendations

SHO-501 Primary Selection: The SHO-501 is the specified component for applications requiring 17.5 µH inductance at 100 kHz with minimal DC resistance (105 mOhm). This part is Active in product status with ROHS3 compliance and 777 pieces in current inventory.

SHO-402 Substitute Selection: The SHO-402 is a valid substitute when higher inductance filtering (99 µH @ 100 kHz) is acceptable or required by circuit design. The SHO-402 maintains identical electrical ratings (800 mA, 50 V DC) and compliance certifications (ROHS3). The increased DC resistance (120 mOhm, +15 mOhm) and larger physical dimensions (0.295" Dia / 7.50 mm) must be verified for PCB layout compatibility and thermal performance in the target application. The SHO-402 is Active in product status with 1309 pieces in current inventory.

Both parts are suitable for power line filtering in dual-conductor circuits within the specified temperature range (-25°C to 80°C) and voltage rating (50 V DC).

Frequently Asked Questions (FAQ)

Q: Can the SHO-402 replace the SHO-501 in any application?

A: The SHO-402 can replace the SHO-501 only when the higher inductance value (99 µH vs. 17.5 µH at 100 kHz) is compatible with the circuit design. The increased DC resistance (120 mOhm vs. 105 mOhm) and larger physical footprint (0.295" Dia vs. 0.244" Dia) must be accommodated by the PCB layout and thermal design.

Q: What are the key differences between SHO-501 and SHO-402?

A: The primary differences are inductance (17.5 µH vs. 99 µH), DC resistance (105 mOhm vs. 120 mOhm), and physical size (6.20 mm vs. 7.50 mm diameter and height). All other electrical parameters, ratings, and compliance certifications are identical.

Q: Are both parts ROHS3 compliant?

A: Yes, both the SHO-501 and SHO-402 are ROHS3 compliant and suitable for applications requiring environmental compliance.

Q: What is the current rating for both parts?

A: Both the SHO-501 and SHO-402 have a maximum current rating of 800 mA and a DC voltage rating of 50 V.

Q: Will the SHO-402's larger size fit in my PCB layout?

A: The SHO-402 has a diameter and height of 0.295" (7.50 mm) compared to the SHO-501's 0.244" (6.20 mm). PCB layout verification is required to confirm physical compatibility with your specific board design.

Q: What is the operating temperature range for both parts?

A: Both the SHO-501 and SHO-402 operate within the temperature range of -25°C to 80°C.
