Substitute Part Grouping Explanation

Substitute parts for the Bourns 8113 are classified based on strict electrical and mechanical parameter matching:

Direct Manufacturer Substitute (Same Manufacturer): The 8113-RC maintains identical electrical specifications: 5 mH inductance at 1 kHz, 8.9A current rating, and 22mOhm DCR. Physical dimensions, mounting type, and pin configuration are unchanged. The primary distinction is product status (active vs. obsolete) and packaging format (bulk vs. standard).

Cross-Manufacturer Equivalent (Different Manufacturer): The Triad Magnetics CMT-8113 matches all critical electrical parameters: 5 mH @ 1 kHz inductance, 8.9A current capacity, and 22mOhm DCR. Physical footprint, mounting configuration, and pin layout are identical. This part includes additional AC voltage rating (1500V) and expanded approval certifications (CSA, IEC, UL, VDE) not specified for the original part.

Substitution Criteria:

• Inductance value: 5 mH @ 1 kHz (mandatory match)
• Current rating: 8.9A minimum (mandatory match)
• DC resistance: 22mOhm maximum (mandatory match)
• Number of lines: 2 (mandatory match)
• Mounting type: Through Hole (mandatory match)
• Physical dimensions: 1.450" L x 0.800" W, 1.500" height maximum (mandatory match)
• Package configuration: Vertical, 4 PC Pin (mandatory match)
• Operating temperature range: -55°C ~ 105°C (mandatory match)

Frequently Asked Questions (FAQ)

Q: Can the Bourns 8113-RC be used as a direct replacement for the obsolete Bourns 8113? A: Yes. The 8113-RC maintains identical inductance (5 mH @ 1 kHz), current rating (8.9A), DC resistance (22mOhm), physical dimensions, and pin configuration. The primary difference is product status (active vs. obsolete) and RoHS compliance level.

Q: What are the key electrical parameters that determine substitutability for this common mode choke? A: Inductance value (5 mH @ 1 kHz), current rating (8.9A minimum), DC resistance (22mOhm maximum), and number of lines (2) are the critical electrical parameters. All substitute parts match these specifications exactly.

Q: Are the physical dimensions identical across all three part numbers? A: Yes. All three parts share identical dimensions: 1.450" L x 0.800" W (36.83mm x 20.32mm) with maximum height of 1.500" (38.10mm), and use the same vertical 4-pin through-hole package configuration.

Q: What is the difference between the Bourns 8113-RC and the Triad Magnetics CMT-8113? A: Both parts match all core electrical and mechanical specifications. The CMT-8113 includes specified AC voltage rating (1500V) and expanded approval certifications (CSA, IEC, UL, VDE). Selection depends on specific regulatory or safety requirements for the application.

Q: Is the operating temperature range the same for all substitute parts? A: Yes. All three parts operate across the identical temperature range of -55°C to 105°C.

Q: Which substitute part should be selected for new product designs? A: The Bourns 8113-RC is the recommended choice for new designs, as it is the direct manufacturer substitute with active product status and ROHS3 compliance. The Triad Magnetics CMT-8113 is suitable when additional certifications or AC voltage rating specifications are required.
