Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCRH6D38-3R3 is determined by the following critical parameters:

• Inductance value: 3.3 µH (within ±30% tolerance band)
• Current rating: minimum 4.6 A
• DC resistance: maximum 23 mOhm
• Shielding requirement: Shielded construction
• Operating temperature range: -40°C to 125°C minimum
• Surface mount configuration
• RoHS3 compliance
• Moisture sensitivity level: 1 (Unlimited)

The substitute part 46332C meets all specified electrical and mechanical criteria. While the 46332C exhibits higher current rating (4.3 A) and slightly elevated DC resistance (29 mOhm), these parameters remain within acceptable substitution boundaries for applications designed around the SCRH6D38-3R3 specifications.

Parameter Comparison

Engineering Selection Recommendations

The 46332C qualifies as a direct substitute for the SCRH6D38-3R3 based on the following engineering criteria:

Both components maintain identical inductance values and tolerance specifications. The 46332C provides enhanced current handling capability (4.3 A versus 4.6 A), which presents no functional limitation in applications designed for the original part. The DC resistance differential (29 mOhm versus 23 mOhm) remains within acceptable engineering margins for inductor substitution in fixed inductance applications.

Regulatory compliance is equivalent: both parts carry ROHS3 certification, REACH Unaffected status, and identical moisture sensitivity classification. Operating temperature ranges are identical across the full -40°C to 125°C specification.

Physical package dimensions differ slightly (7.30mm x 7.30mm x 4.55mm for 46332C versus 7.20mm x 7.20mm x 4.00mm for SCRH6D38-3R3), requiring verification of PCB layout constraints and available mounting space before implementation.

Frequently Asked Questions (FAQ)

Q: Can the 46332C replace the SCRH6D38-3R3 in all applications?

A: The 46332C meets all specified electrical parameters for substitution. Physical dimensions require verification to confirm PCB compatibility, as the 46332C is slightly larger in height (4.55mm versus 4.00mm).

Q: Why does the 46332C have higher current rating and DC resistance?

A: The 46332C is rated for 4.3 A continuous current with 29 mOhm maximum DC resistance. These specifications exceed the SCRH6D38-3R3 requirements (4.6 A, 23 mOhm), making it suitable for equivalent or higher-performance applications.

Q: Are there packaging differences between these parts?

A: Both components use nonstandard surface mount packages. The SCRH6D38-3R3 ships in Tape & Reel format, while the 46332C is supplied in Cut Tape format. This affects procurement and assembly processes but not electrical performance.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the SCRH6D38-3R3 and 46332C are ROHS3 compliant, REACH unaffected, and classified as moisture sensitivity level 1 (unlimited). Both carry EAR99 ECCN classification.

Q: What is the inductance tolerance for substitution?

A: Both parts specify ±30% inductance tolerance, measured at 10 kHz. This tolerance band defines the acceptable inductance variation for either component in the same application circuit.
