VCHA075D-220MS6 Equivalent & Substitute Parts

Part Overview

The VCHA075D-220MS6 is a 22 µH unshielded surface mount inductor manufactured by Delta Electronics/Cyntec, rated for 3.3 A continuous current with a maximum DC resistance of 94.6 mOhm. This component is classified as Active and meets AEC-Q200 automotive qualification standards. The part is supplied in Tape & Reel packaging with RoHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified when design requirements permit variations in shielding characteristics, current ratings, or core materials while maintaining the specified inductance value of 22 µH, tolerance of ±20%, and operating temperature range compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the VCHA075D-220MS6 are qualified based on the following criteria:

Primary Matching Parameters:

• Inductance value: 22 µH (exact match required)
• Inductance tolerance: ±20% (exact match required)
• Inductance test frequency: 100 kHz (exact match required)
• Surface mount packaging and nonstandard case dimensions
• AEC-Q200 qualification
• RoHS3 compliance

Allowable Variations:

• Current rating: May exceed the 3.3 A requirement
• DC resistance: May be lower than 94.6 mOhm maximum
• Shielding: May differ from unshielded configuration
• Core material: May vary (metal, alloy powder, or other)
• Operating temperature range: Must encompass or match the -55°C ~ 165°C range
• Physical dimensions: Minor variations acceptable within nonstandard package classification

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts meet the core electrical and compliance requirements for replacement of the VCHA075D-220MS6:

HCM1A0805V2-220-R (Eaton - Electronics Division): This part maintains AEC-Q200 qualification and RoHS3 compliance. The 4.6 A current rating exceeds the original specification, and the 70 mOhm maximum DC resistance is lower than the original 94.6 mOhm, resulting in reduced power dissipation. The shielded configuration differs from the original unshielded design. The operating temperature range of -55°C ~ 155°C is 10°C lower at the upper limit compared to the original specification.

SRP7050WA-220M (Bourns Inc.): This part maintains AEC-Q200 qualification and RoHS3 compliance with an operating temperature range of -55°C ~ 165°C, matching the original specification. The 5 A current rating and 6.3 A saturation current provide increased margin above the original 3.3 A requirement. The DC resistance matches the original 94.6 mOhm maximum specification. The shielded configuration differs from the original unshielded design.

Selection between substitutes depends on application-specific requirements regarding shielding, thermal performance, and maximum operating temperature constraints.

Frequently Asked Questions (FAQ)

Q: Can HCM1A0805V2-220-R be used as a direct replacement for VCHA075D-220MS6?

A: HCM1A0805V2-220-R qualifies as a substitute based on matching inductance (22 µH), tolerance (±20%), test frequency (100 kHz), and AEC-Q200 qualification. The higher current rating (4.6 A vs. 3.3 A) and lower DC resistance (70 mOhm vs. 94.6 mOhm) are compatible with applications designed for the original part. The shielded configuration may affect electromagnetic coupling in the circuit. The upper operating temperature limit of 155°C is 10°C lower than the original 165°C specification.

Q: Can SRP7050WA-220M be used as a direct replacement for VCHA075D-220MS6?

A: SRP7050WA-220M qualifies as a substitute based on matching inductance (22 µH), tolerance (±20%), test frequency (100 kHz), AEC-Q200 qualification, and operating temperature range (-55°C ~ 165°C). The higher current rating (5 A vs. 3.3 A) and saturation current (6.3 A vs. 5.4 A) provide increased design margin. The DC resistance matches the original specification at 94.6 mOhm maximum. The shielded configuration differs from the original unshielded design.

Q: What is the significance of shielding differences between the original and substitute parts?

A: The VCHA075D-220MS6 is unshielded, while both substitutes (HCM1A0805V2-220-R and SRP7050WA-220M) are shielded. Shielding reduces electromagnetic radiation and susceptibility to external magnetic fields. In applications where the original unshielded design was selected for specific coupling characteristics or where shielding may introduce undesired effects, this difference must be evaluated against circuit requirements.

Q: Are all three parts qualified to the same automotive standard?

A: Yes, all three parts carry AEC-Q200 qualification and RoHS3 compliance. All parts are rated for surface mount assembly with unlimited moisture sensitivity level (MSL 1).

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

A: The VCHA075D-220MS6 measures 0.303" L x 0.283" W (7.70mm x 7.20mm) with a seated height of 0.213" (5.40mm). The HCM1A0805V2-220-R measures 0.319" L x 0.315" W (8.10mm x 8.00mm) with the same seated height of 0.213" (5.40mm). The SRP7050WA-220M measures 0.311" L x 0.287" W (7.90mm x 7.30mm) with the same seated height of 0.213" (5.40mm). All three parts have identical seated heights, but footprint dimensions vary slightly.
