Equivalent & Substitute Parts for Bourns 9230-72

Part Overview

The Bourns 9230-72 is a 150 µH unshielded molded inductor rated for 85 mA with 15Ω maximum DC resistance, designed for through-hole axial mounting. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The 9230 series represents a legacy product line that has been superseded by active alternatives offering improved compliance and performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Bourns 9230-72 is determined by the following critical parameters:

• Inductance Value: 150 µH (exact match required)
• Inductance Tolerance: ±10% (exact match required)
• DC Resistance: 15Ω Max (exact match required)
• Q Factor @ 790 kHz: 30 (exact match required)
• Self Resonant Frequency: 11 MHz (exact match required)
• Mounting Type: Through Hole Axial (exact match required)
• Current Rating: Minimum 85 mA (equal or greater acceptable)
• Operating Temperature Range: Minimum -55°C ~ 125°C (equal or greater range acceptable)

Substitute parts are grouped into two categories based on shielding configuration and current handling capacity. The API Delevan 1025-72K maintains unshielded construction but operates at reduced current (61 mA), suitable only for applications with lower current demands. The TE Connectivity SC30151KT and 1624006-1 provide shielded construction with enhanced current rating (108 mA), appropriate for noise-sensitive applications requiring higher current capacity.

Parameter Comparison

Engineering Selection Recommendations

API Delevan 1025-72K: This substitute maintains identical electrical characteristics and physical dimensions to the Bourns 9230-72 with unshielded construction. However, the current rating is reduced to 61 mA, making this option suitable only for applications where circuit current does not exceed 61 mA. The part remains RoHS non-compliant. Selection of this part is appropriate for direct form-fit-function replacement in legacy designs with lower current requirements.

TE Connectivity SC30151KT and 1624006-1: Both parts provide shielded construction with enhanced current rating of 108 mA, exceeding the original 85 mA specification. These parts are ROHS3 compliant and carry active product status. Physical dimensions are larger (0.165" Dia x 0.394" L versus 0.095" Dia x 0.250" L), requiring PCB layout verification. Operating temperature range is reduced to -55°C ~ 100°C. Selection of these parts is appropriate for new designs or redesigns where compliance requirements and EMI shielding are priorities, provided board space accommodates the larger package.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan 1025-72K directly replace the Bourns 9230-72 in all applications?

A: The 1025-72K maintains identical inductance, tolerance, DCR, Q factor, and self-resonant frequency specifications. However, the current rating is 61 mA versus 85 mA. Direct replacement is valid only if circuit current does not exceed 61 mA. Exceeding this rating will cause inductor saturation and performance degradation.

Q: What is the primary advantage of the TE Connectivity SC30151KT and 1624006-1 substitutes?

A: Both parts provide shielded construction, reducing electromagnetic interference in sensitive circuits. Current rating is increased to 108 mA, providing margin above the original 85 mA specification. Both parts are ROHS3 compliant and carry active product status, ensuring long-term availability and regulatory compliance.

Q: Are there physical compatibility concerns with the TE Connectivity substitutes?

A: Yes. The TE Connectivity parts measure 0.165" Dia x 0.394" L, compared to 0.095" Dia x 0.250" L for the original Bourns part. PCB layout must be verified to accommodate the larger axial package. Clearance to adjacent components and trace routing must be confirmed before implementation.

Q: What is the impact of the reduced operating temperature range in the TE Connectivity substitutes?

A: The TE Connectivity parts operate to -55°C ~ 100°C, versus -55°C ~ 125°C for the Bourns original. Applications requiring operation above 100°C cannot use these substitutes. Circuit thermal analysis must confirm that operating temperature remains within the -55°C ~ 100°C window.

Q: Are there compliance differences between substitute options?

A: The API Delevan 1025-72K remains RoHS non-compliant, matching the original part. The TE Connectivity SC30151KT and 1624006-1 are ROHS3 compliant. For new designs or applications subject to RoHS regulations, the TE Connectivity options are required.

Q: What is the difference between SC30151KT and 1624006-1?

A: Both parts are electrically and mechanically identical. SC30151KT is packaged in Tape & Box (TB) format, while 1624006-1 is supplied in bulk packaging. Selection depends on procurement and assembly requirements. Electrical performance and physical dimensions are equivalent.
