Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SCRH103R-150 are qualified based on the following critical parameters:

• Inductance value: 15 µH (exact match required)
• Inductance tolerance: ±30% (must accommodate specification)
• Current rating: minimum 2.24 A (equal or greater acceptable)
• DC resistance: 86 mOhm maximum (lower values acceptable for improved performance)
• Shielding: Shielded construction (required for EMI containment)
• Mounting type: Surface Mount (package compatibility)
• Operating temperature: -40°C to 125°C (must meet or exceed range)
• Compliance: RoHS and REACH status alignment

The substitute parts DR1030-150-R and SD8328-150-R meet these criteria with equivalent or superior electrical characteristics and active product status.

Parameter Comparison

Engineering Selection Recommendations

Both DR1030-150-R and SD8328-150-R are qualified substitutes for SCRH103R-150 based on electrical parameter equivalence and compliance certifications.

DR1030-150-R offers improved DC resistance performance at 68.8 mOhm maximum compared to the original 86 mOhm specification, with higher saturation current rating of 2.66 A. This part maintains ROHS3 compliance and active product status with 1900 units in stock.

SD8328-150-R provides comparable DC resistance at 69 mOhm maximum with current rating of 2.35 A. This part is RoHS compliant with active product status and 2180 units in stock. Physical dimensions differ slightly (0.374" L x 0.327" W versus 0.413" L x 0.406" W), requiring PCB layout verification for space-constrained applications.

Both substitutes maintain the required shielded construction, operating temperature range, and tape & reel packaging format. Selection between substitutes should be based on PCB footprint compatibility and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can DR1030-150-R or SD8328-150-R be used as direct replacements for SCRH103R-150?

A: Yes, both parts meet the electrical substitution criteria. The 15 µH inductance value, ±30% tolerance, shielded construction, and operating temperature range are identical. Current ratings of 2.3 A and 2.35 A exceed the original 2.24 A specification. DC resistance values of 68.8 mOhm and 69 mOhm are lower than the 86 mOhm maximum, which improves thermal performance. PCB layout verification is required for SD8328-150-R due to different physical dimensions.

Q: What are the key differences between the two substitute parts?

A: DR1030-150-R features higher saturation current (2.66 A) and maintains identical physical dimensions to the original part (0.413" L x 0.406" W). SD8328-150-R has a smaller footprint (0.374" L x 0.327" W) with saturation current of 2 A. Both have equivalent DC resistance performance and compliance certifications.

Q: Are there compliance or certification differences between these parts?

A: SCRH103R-150 and DR1030-150-R are both ROHS3 compliant. SD8328-150-R is RoHS compliant. All three parts are REACH unaffected and carry MSL rating of 1 (Unlimited). For applications requiring ROHS3 specifically, DR1030-150-R is the preferred substitute.

Q: What packaging format is used for these inductors?

A: All three parts are supplied in Tape & Reel (TR) format for automated assembly processes. Moisture sensitivity level is 1 (Unlimited) for all parts, indicating no special storage or handling requirements.

Q: How do the physical dimensions affect PCB design?

A: SCRH103R-150 and DR1030-150-R share identical dimensions (0.413" L x 0.406" W x 0.122" H maximum). SD8328-150-R has a smaller footprint (0.374" L x 0.327" W x 0.118" H maximum), which may allow for denser PCB layouts but requires footprint verification before implementation.
