Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and ROHS3 compliance, ensuring regulatory alignment with the original SS21V-R200036 specification. Selection among substitute parts depends on circuit-specific inductance requirements and current handling capacity.

SS24V-R20045-CH provides the highest inductance value at 4.5 mH with identical 2A current rating and 250V AC voltage specification. This part accommodates applications requiring increased filtering performance at the cost of elevated DC resistance (170 mOhm).

SS21V-200024 offers intermediate inductance at 2.4 mH with matching 2A current rating and 150 mOhm DC resistance, providing a closer inductance alternative to the primary part while maintaining identical electrical characteristics.

SS11VL-R22020 and SS11VL-22013 deliver reduced inductance values (2 mH and 1.3 mH respectively) with enhanced current capacity (2.2A) and lower DC resistance (120 mOhm). These parts suit applications with lower inductance requirements and higher current margins.

SU10VFC-R20010 represents the lowest inductance option at 1 mH with compact physical dimensions, suitable for space-constrained applications requiring minimal filtering inductance.

All substitute parts maintain identical mounting configuration, voltage rating, and operating temperature range, ensuring direct mechanical and electrical compatibility within the specified parameter envelope.

Frequently Asked Questions (FAQ)

Q: Can SS21V-R200036 be directly replaced with SS21V-200024?

A: Yes. Both parts share identical current rating (2A), DC resistance (150 mOhm), voltage rating (250V AC), mounting type (Through Hole), and operating temperature range (-25°C to 120°C). The inductance difference (3.6 mH versus 2.4 mH) requires circuit validation to confirm filtering performance meets application requirements.

Q: What is the primary difference between SS11VL series and SS21V series substitutes?

A: The SS11VL series (SS11VL-R22020, SS11VL-22013) provides higher current capacity (2.2A) and lower DC resistance (120 mOhm) compared to SS21V series parts. Physical dimensions also differ, with SS11VL parts measuring 22.00mm x 14.50mm versus SS21V parts at 20.50mm x 16.50mm. Both series maintain identical voltage and temperature specifications.

Q: Is SU10VFC-R20010 suitable for applications requiring 3.6 mH inductance?

A: No. SU10VFC-R20010 provides only 1 mH inductance at 1 kHz, significantly lower than the 3.6 mH specification of SS21V-R200036. This part is applicable only to applications with reduced inductance requirements. Physical dimensions are also substantially smaller (18.00mm x 15.50mm).

Q: Do all substitute parts maintain ROHS3 compliance?

A: Yes. All listed substitute parts are ROHS3 compliant and maintain Active product status, ensuring regulatory and supply chain continuity with the original SS21V-R200036 specification.

Q: What inductance range is available across all substitute options?

A: Substitute parts span inductance values from 1 mH (SU10VFC-R20010) to 4.5 mH (SS24V-R20045-CH), with intermediate options at 1.3 mH, 2 mH, 2.4 mH, and 3.6 mH. Selection depends on specific circuit filtering requirements and frequency response characteristics.

Q: Are there dimensional constraints when selecting substitute parts?

A: Yes. Physical dimensions vary across substitute options. SS21V-R200036 measures 20.50mm L x 16.50mm W x 24.50mm H. SS24V-R20045-CH is larger at 26.00mm x 19.00mm x 31.50mm. SS11VL series measures 22.00mm x 14.50mm x 19.50mm. SU10VFC-R20010 is smallest at 18.00mm x 15.50mm x 15.00mm. PCB layout and enclosure space must accommodate selected part dimensions.

Q: Can current rating differences affect part selection?

A: Yes. SS21V-R200036 is rated for 2A maximum current. SS11VL-R22020 and SS11VL-22013 support 2.2A, providing additional current margin. Applications operating near 2A should consider higher-rated alternatives to ensure thermal stability and extended component life.
