Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HC8LP-220-R are qualified based on the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Inductance value: 22 µH (matching tolerance ±20%)
• Mounting type: Surface Mount
• Package category: Nonstandard (compatible footprint dimensions)
• Core type: Drum Core, Wirewound construction
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1 (Unlimited)

Secondary Compatibility Parameters:

• Current rating capability equal to or exceeding 2.8 A
• DC resistance within acceptable limits for the application
• Operating temperature range encompassing -40°C to 155°C minimum
• Inductance test frequency: 100 kHz

The SRP1038A-220M from Bourns Inc. meets these substitution criteria with equivalent inductance, superior current handling (5 A rating), lower DC resistance (74 mOhm), and compatible surface mount construction.

Engineering Selection Recommendations

HC8LP-220-R Selection: Choose the HC8LP-220-R when the unshielded configuration is required for the application and the 2.8 A current rating is sufficient. This part is ROHS3 compliant and maintains active product status with established supply availability.

SRP1038A-220M Selection: The SRP1038A-220M is suitable as a substitute when higher current capacity (5 A rating) or lower DC resistance (74 mOhm versus 149 mOhm) is beneficial to the circuit design. The shielded construction provides electromagnetic interference mitigation. This part carries AEC-Q200 automotive qualification and ROHS3 compliance. The operating temperature maximum of 150°C is 5°C lower than the HC8LP-220-R; applications requiring operation above 150°C must use the HC8LP-220-R.

Both parts maintain ROHS3 compliance, MSL 1 rating, and active product status, ensuring long-term availability and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can the SRP1038A-220M directly replace the HC8LP-220-R in all applications?

A: The SRP1038A-220M is electrically compatible for applications operating at or below 150°C. Applications requiring operation between 150°C and 155°C must retain the HC8LP-220-R. The shielded construction of the SRP1038A-220M may affect circuit behavior in applications sensitive to electromagnetic coupling; unshielded operation may be required in such cases.

Q: What is the impact of different core materials (Iron Powder versus Carbonyl Powder)?

A: Core material differences affect inductor characteristics including Q factor, frequency response, and saturation behavior. The SRP1038A-220M specifies Q @ 100 kHz of 20 and self-resonant frequency of 8 MHz. These parameters are not provided for the HC8LP-220-R. Material selection should align with the specific frequency and performance requirements of the application.

Q: Are the physical dimensions compatible between these parts?

A: Both parts are classified as Nonstandard package. The HC8LP-220-R measures 0.429" L × 0.409" W × 0.138" H (10.90mm × 10.40mm × 3.50mm). The SRP1038A-220M measures 0.433" L × 0.394" W × 0.157" H (11.00mm × 10.00mm × 4.00mm). Dimensional differences require PCB layout verification before substitution.

Q: What is the significance of the lower DC resistance in the SRP1038A-220M?

A: The SRP1038A-220M exhibits 74 mOhm maximum DC resistance compared to 149 mOhm for the HC8LP-220-R. Lower DC resistance reduces resistive losses and heat generation at rated current, improving efficiency. This characteristic is particularly beneficial in high-current or thermally constrained applications.

Q: Do both parts carry the same compliance certifications?

A: Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings. The SRP1038A-220M additionally carries AEC-Q200 automotive qualification. Both parts maintain active product status.
