Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDH113NP-150MC is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 15 µH (exact match required)
• Mounting type: Surface Mount (exact match required)
• Inductance tolerance: ±20% or tighter acceptable
• DC resistance: Must not exceed 72mOhm maximum

Secondary Compatibility Factors:

• Current rating: Substitute must equal or exceed 1.55 A
• Operating temperature range: Substitute must cover or exceed -30°C to 100°C
• Shielding configuration: Unshielded or shielded acceptable based on circuit requirements
• RoHS compliance: ROHS3 compliance required

The SCRH103R-150 manufactured by Signal Transformer meets the primary inductance and mounting requirements with a 15 µH specification and surface mount configuration. This substitute provides enhanced current handling capability at 2.24 A and operates across an extended temperature range of -40°C to 125°C, exceeding the original part specifications.

Parameter Comparison

Engineering Selection Recommendations

The SCRH103R-150 is a qualified substitute for the CDH113NP-150MC based on the following engineering criteria:

Electrical Compatibility: Both components provide 15 µH inductance at surface mount configuration. The SCRH103R-150 exceeds the current rating requirement (2.24 A versus 1.55 A) and extends the operating temperature range (-40°C to 125°C versus -30°C to 100°C), providing enhanced performance margins.

Compliance Status: Both parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring regulatory and moisture sensitivity requirements are preserved.

Availability and Product Status: The SCRH103R-150 is classified as Active with 1055 units in stock, compared to the obsolete CDH113NP-150MC status. This ensures long-term procurement viability and supply chain continuity.

Physical Considerations: The SCRH103R-150 features a slightly smaller footprint (10.50mm x 10.30mm versus 11.20mm x 11.00mm) and reduced height (3.10mm versus 3.70mm), which may provide layout advantages in space-constrained applications.

Shielding Difference: The SCRH103R-150 is shielded while the original part is unshielded. Circuit-level electromagnetic compatibility assessment is required to determine if shielding introduces any functional changes to the application.

Frequently Asked Questions (FAQ)

Q: Can the SCRH103R-150 directly replace the CDH113NP-150MC in all applications?

A: The SCRH103R-150 meets the core electrical specifications (15 µH inductance, surface mount, current rating exceeds requirement). However, the shielding difference requires circuit-level evaluation. The shielded configuration may alter electromagnetic coupling characteristics in sensitive circuits. Physical footprint differences (10.50mm x 10.30mm versus 11.20mm x 11.00mm) must be verified against PCB layout constraints.

Q: What is the significance of the DC resistance difference (72mOhm versus 86mOhm)?

A: The SCRH103R-150 exhibits 14mOhm higher DC resistance. In applications where inductor losses directly impact efficiency or thermal performance, this difference must be evaluated. For most general-purpose filtering and energy storage applications, this variance remains within acceptable engineering margins.

Q: Why does the SCRH103R-150 have a wider inductance tolerance (±30% versus ±20%)?

A: The broader tolerance specification reflects the manufacturing process of the substitute part. For applications requiring tighter inductance control, circuit-level compensation or selection binning may be necessary. The 15 µH nominal value remains identical.

Q: Are there any packaging or supply chain advantages to using the SCRH103R-150?

A: The SCRH103R-150 is supplied in Tape & Reel (TR) packaging with Active product status and higher inventory availability (1055 units). The CDH113NP-150MC is obsolete with limited remaining stock (950 units). The substitute provides superior long-term procurement reliability.

Q: How does the extended temperature range of the SCRH103R-150 affect application suitability?

A: The SCRH103R-150 operates from -40°C to 125°C compared to the original -30°C to 100°C range. This extended specification provides additional thermal margin and enables use in wider environmental conditions without performance degradation.
