Substitute Part Grouping Explanation

Substitute parts for the 1008HC-152EKFS are classified into two categories based on electrical parameter compatibility:

Direct Substitutes (Electrical Equivalents): Parts that maintain the same inductance value (1.5 µH), operate within compatible current ratings (≥550 mA), and are housed in the identical 1008 (2520 Metric) package. These parts satisfy the core electrical requirements of the original specification.

• 744758315A (Würth Elektronik WE-RFH series): 630 mA rating, 750 mOhm DCR
• AISC-1008F-1R5G-T (Abracon LLC AISC-1008F series): 630 mA rating, 760 mOhm DCR

Similar Parts (Functional Alternatives): Parts that share the same inductance value and package but operate at reduced current ratings (220–280 mA) with significantly different DC resistance characteristics. These parts are suitable only for applications where the lower current rating is acceptable.

• CW252016-1R5J (Bourns Inc. CW252016 series): 280 mA rating, 2.3 Ohm DCR
• NLV25T-1R5J-EF (TDK Corporation NLV-EF series): 220 mA rating, 1.3 Ohm DCR

Substitution Criteria:

• Inductance: 1.5 µH (fixed requirement)
• Package: 1008 (2520 Metric) (fixed requirement)
• Current Rating: Must equal or exceed 550 mA for direct substitution
• DC Resistance: Acceptable range 450 mOhm to 760 mOhm for direct substitutes
• Core Material: Ferrite (fixed requirement)
• Shielding: Unshielded (fixed requirement)
• Mounting: Surface Mount (fixed requirement)

Engineering Selection Recommendations

For Direct Substitution (Equivalent Current Handling):

The 744758315A (Würth Elektronik WE-RFH series) and AISC-1008F-1R5G-T (Abracon LLC AISC-1008F series) are the primary direct substitutes for the 1008HC-152EKFS. Both parts maintain the 1.5 µH inductance specification, support current ratings of 630 mA (exceeding the original 550 mA requirement), and are housed in the identical 1008 (2520 Metric) package.

744758315A offers active product status with ROHS3 compliance and REACH unaffected designation. DC resistance of 750 mOhm is within acceptable tolerance of the original 450 mOhm specification for applications where resistance variation is non-critical.

AISC-1008F-1R5G-T provides the tightest inductance tolerance (±2%) among all candidates, superior Q factor (35 @ 50 MHz), and active product status with extensive inventory availability (195,110 pieces). DC resistance of 760 mOhm is comparable to the Würth part. This part is recommended as the primary replacement for new designs and ongoing production.

Both direct substitutes are ROHS3 compliant with MSL 1 rating, ensuring compatibility with standard manufacturing processes.

For Current-Limited Applications:

The CW252016-1R5J (Bourns Inc.) and NLV25T-1R5J-EF (TDK Corporation) are suitable only for applications where circuit current requirements do not exceed 280 mA and 220 mA respectively. These parts exhibit significantly higher DC resistance (2.3 Ohm and 1.3 Ohm) and are not interchangeable with the original specification for standard 550 mA operation.

CW252016-1R5J supports extended operating temperature to 125°C and maintains ROHS3 compliance with REACH unaffected status.

NLV25T-1R5J-EF operates to 105°C maximum and carries REACH affected designation, requiring additional compliance verification for regulated applications.

Frequently Asked Questions (FAQ)

Q: Can the 744758315A directly replace the 1008HC-152EKFS in all applications?

A: The 744758315A is electrically compatible for applications operating at or below 630 mA. The inductance value (1.5 µH) and package (1008 2520 Metric) are identical. DC resistance increases from 450 mOhm to 750 mOhm maximum, which may affect circuit performance in applications sensitive to resistance variation. Verify circuit tolerance specifications before implementation.

Q: What is the primary advantage of AISC-1008F-1R5G-T over other substitutes?

A: The AISC-1008F-1R5G-T provides the tightest inductance tolerance (±2% versus ±5–10%), highest Q factor (35 @ 50 MHz), and largest available inventory (195,110 pieces). These characteristics make it the most suitable replacement for precision applications and high-volume production requirements.

Q: Why are CW252016-1R5J and NLV25T-1R5J-EF classified as similar parts rather than direct substitutes?

A: Both parts operate at significantly reduced current ratings (280 mA and 220 mA respectively) compared to the original 550 mA specification. They are suitable only for applications where circuit current requirements are within their rated limits. DC resistance is also substantially higher (1.3–2.3 Ohm versus 450 mOhm), affecting circuit impedance characteristics.

Q: Are all substitute parts ROHS3 compliant?

A: All five parts (main and four substitutes) are ROHS3 compliant. However, NLV25T-1R5J-EF carries REACH affected status, requiring additional regulatory verification for applications subject to REACH restrictions. The remaining parts are REACH unaffected.

Q: What is the moisture sensitivity level for these inductors?

A: All parts, including the original 1008HC-152EKFS and all substitutes, carry MSL 1 (Unlimited) rating. This indicates no moisture sensitivity restrictions and compatibility with standard surface mount assembly processes without special handling requirements.

Q: Can I use CW252016-1R5J or NLV25T-1R5J-EF in a 550 mA circuit?

A: No. Both parts are rated for maximum continuous currents of 280 mA and 220 mA respectively. Operating these parts at 550 mA will exceed their current rating and result in component failure or performance degradation. Use only the direct substitutes (744758315A or AISC-1008F-1R5G-T) for 550 mA applications.

Q: How does the operating temperature range affect part selection?

A: The original 1008HC-152EKFS operates from -40°C to 85°C. Direct substitutes (744758315A and AISC-1008F-1R5G-T) maintain this identical range. CW252016-1R5J extends to 125°C, and NLV25T-1R5J-EF to 105°C. Select parts based on your application's thermal requirements; higher temperature ratings provide additional design margin but are not required for standard -40°C to 85°C operation.

Q: What packaging format is available for these parts?

A: All substitute parts are supplied in Tape & Reel (TR) format, suitable for automated assembly processes. The original 1008HC-152EKFS packaging format is not specified in the provided data but is compatible with standard 1008 (2520 Metric) package handling.
