Bourns 9250-152 Equivalent & Substitute Parts

Part Overview

The Bourns 9250-152 is a 1.5 µH shielded drum core wirewound inductor rated for 815 mA with a maximum DC resistance of 120 mOhm. This axial through-hole component operates across the temperature range of -55°C to 105°C and is designed for applications requiring fixed inductance with electromagnetic shielding.

The 9250-152 is classified as obsolete. Equivalent substitute parts from API Delevan Inc. are available as active alternatives, offering identical electrical specifications and mechanical compatibility while maintaining current product status and supply availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Bourns 9250-152 is determined by the following critical parameters:

• Inductance Value: 1.5 µH with ±10% tolerance
• Current Rating: 815 mA minimum
• DC Resistance: 120 mOhm maximum
• Shielding: Shielded construction required
• Mounting Configuration: Through-hole axial package
• Physical Dimensions: 0.162" Dia x 0.410" L (4.11mm x 10.41mm)
• Operating Temperature: -55°C to 105°C
• Electrical Performance: Q factor of 44 @ 7.9 MHz and self-resonant frequency of 115 MHz

The three API Delevan ER1641 series inductors (ER1641-152KM, ER1641-152KP, ER1641-152KR) meet all these substitution criteria. These parts differ from the original Bourns design in core material composition (iron core molded construction versus ferrite drum core) and product status (active versus obsolete), but maintain electrical and mechanical equivalence for direct circuit replacement.

Parameter Comparison

Engineering Selection Recommendations

The API Delevan ER1641 series inductors (ER1641-152KM, ER1641-152KP, ER1641-152KR) provide direct electrical and mechanical substitution for the obsolete Bourns 9250-152. All three variants maintain identical electrical specifications and physical dimensions, ensuring pin-compatible replacement in existing circuit designs.

Selection among the three API Delevan alternatives is based on packaging and supply requirements:

• ER1641-152KP: 1088 units in stock, highest inventory availability
• ER1641-152KR: 1054 units in stock, comparable availability
• ER1641-152KM: 742 units in stock, lowest inventory level

All three parts carry identical regulatory compliance: RoHS non-compliant, REACH Unaffected, ECCN EAR99, and HTSUS 8504.50.8000. The active product status of the ER1641 series ensures continued supply and technical support compared to the obsolete Bourns 9250-152.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan ER1641 series inductors directly replace the Bourns 9250-152 in existing designs?

A: Yes. The ER1641-152KM, ER1641-152KP, and ER1641-152KR are electrically and mechanically equivalent. All three maintain the same inductance value (1.5 µH), current rating (815 mA), DC resistance (120 mOhm max), shielding, operating temperature range (-55°C to 105°C), and physical dimensions (0.162" Dia x 0.410" L). Through-hole axial mounting is identical, enabling direct PCB replacement without circuit modification.

Q: What is the difference between the three API Delevan substitute part numbers?

A: The ER1641-152KM, ER1641-152KP, and ER1641-152KR are electrically identical. The differences are in packaging configuration (all supplied in Tape & Reel format) and inventory availability. Selection should be based on supply requirements and lead time considerations.

Q: Why does the Bourns 9250-152 use a ferrite drum core while the API Delevan alternatives use iron core construction?

A: Core material composition differs between the designs, but both ferrite and iron core constructions achieve the specified electrical performance parameters. The electrical characteristics—inductance, Q factor, self-resonant frequency, and DC resistance—are equivalent across all parts, confirming functional interchangeability.

Q: Are there any compliance or regulatory differences between the Bourns 9250-152 and the API Delevan ER1641 series?

A: No. All parts share identical regulatory status: RoHS non-compliant, REACH Unaffected, ECCN EAR99, and HTSUS 8504.50.8000. Compliance requirements do not differentiate these components.

Q: What is the primary advantage of selecting an API Delevan ER1641 substitute over the obsolete Bourns 9250-152?

A: The API Delevan ER1641 series maintains active product status with confirmed supply availability (742–1088 units in stock). The Bourns 9250-152 is obsolete, presenting long-term supply risk. Substitution ensures design continuity and component availability for current and future production requirements.
