Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SWC-0.95-1000 are classified based on electrical and mechanical parameter alignment:

Direct Substitutes maintain identical or tighter electrical specifications across inductance, current rating, DC resistance, and core material, with matching through-hole radial vertical mounting and package dimensions.

Similar Substitutes share the same inductance value and mounting type but differ in one or more of the following parameters: current rating, DC resistance, core material, operating temperature range, or physical dimensions. These parts are suitable when the application tolerates the specified parameter variations.

The critical parameters determining substitution eligibility are:

• Inductance value (1 mH)
• Inductance tolerance (±20% or tighter)
• Current rating (minimum 950 mA for direct substitutes; higher ratings acceptable for similar substitutes)
• DC resistance (240 mOhm maximum for direct substitutes; higher values acceptable for similar substitutes)
• Mounting type (Through Hole)
• Package configuration (Radial, Vertical Open)
• Shielding type (Unshielded)

Parameter Comparison

Engineering Selection Recommendations

SH50C-0.95-1000 (Direct Substitute): This part is a direct substitute for the SWC-0.95-1000. Both components share identical electrical specifications (1 mH inductance, 950 mA current rating, 240 mOhm DC resistance), core material (iron powder), and physical dimensions. Both are ROHS3 compliant and active in production. The primary difference is packaging format (tray versus standard packaging) and series designation. This substitute is suitable for direct replacement in all applications where the SWC-0.95-1000 is specified.

2124-V-RC (Similar Substitute): This Bourns Inc. part shares the same 1 mH inductance value and through-hole radial vertical mounting configuration. However, it differs in the following parameters: current rating (1.3 A versus 950 mA), DC resistance (400 mOhm versus 240 mOhm), inductance tolerance (±15% versus ±20%), operating temperature range (-55°C to 105°C versus -40°C to 125°C), and physical dimensions (0.860" Dia x 0.450" W versus 1.252" L x 0.701" W). This part is suitable as a substitute when the application can tolerate higher DC resistance and the reduced upper operating temperature limit, and when the smaller physical footprint is compatible with the PCB layout. The higher current rating provides additional design margin.

All substitute parts maintain ROHS3 compliance and active product status, ensuring availability and regulatory alignment with the original component.

Frequently Asked Questions (FAQ)

Q: Can SH50C-0.95-1000 be used as a direct replacement for SWC-0.95-1000?

A: Yes. The SH50C-0.95-1000 is a direct substitute. Both parts have identical inductance (1 mH), current rating (950 mA), DC resistance (240 mOhm), core material (iron powder), and physical dimensions. The only difference is the packaging format (tray versus standard). No circuit modifications are required.

Q: What are the limitations of using 2124-V-RC as a substitute?

A: The 2124-V-RC has three key differences: (1) DC resistance is 400 mOhm maximum, compared to 240 mOhm for the SWC-0.95-1000, resulting in higher power dissipation; (2) the upper operating temperature limit is 105°C instead of 125°C; (3) physical dimensions are significantly smaller (0.860" Dia x 0.450" W versus 1.252" L x 0.701" W). Verify that your application can tolerate these parameter variations and that the smaller footprint fits the PCB layout.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. Both SH50C-0.95-1000 and 2124-V-RC are ROHS3 compliant, matching the compliance status of the SWC-0.95-1000.

Q: What is the difference between inductance tolerance specifications?

A: The SWC-0.95-1000 and SH50C-0.95-1000 have ±20% tolerance, while the 2124-V-RC has ±15% tolerance. Tighter tolerance (±15%) provides more precise inductance values. If your circuit requires tighter tolerance control, the 2124-V-RC offers this advantage.

Q: How does DC resistance affect circuit performance?

A: DC resistance causes power dissipation (I²R losses) and affects circuit Q factor. The SWC-0.95-1000 and SH50C-0.95-1000 have 240 mOhm maximum resistance. The 2124-V-RC has 400 mOhm maximum resistance, resulting in approximately 67% higher losses at the same current. For applications sensitive to power dissipation or thermal performance, the lower DC resistance of the SWC-0.95-1000 or SH50C-0.95-1000 is preferred.

Q: Can I use 2124-V-RC in a circuit designed for -40°C to 125°C operation?

A: The 2124-V-RC operates only to 105°C maximum. If your application requires operation above 105°C, the 2124-V-RC is not suitable. The SWC-0.95-1000 or SH50C-0.95-1000 must be used for the full -40°C to 125°C temperature range.

Q: What packaging options are available?

A: SWC-0.95-1000 is supplied in standard packaging. SH50C-0.95-1000 is supplied in tray packaging. 2124-V-RC is supplied in bulk packaging. Verify packaging compatibility with your procurement and assembly processes.
