Bourns 9130-00 150nH Wirewound Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 9130-00 is a 150nH unshielded wirewound inductor rated for 1.2A continuous current with 100mOhm maximum DC resistance. This through-hole axial component operates across -55°C to 125°C and is designed for applications requiring low inductance values with controlled impedance characteristics. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications.

Substitute Part Grouping Explanation

Substitution eligibility for the Bourns 9130-00 is determined by the following critical parameters: inductance value (150nH ±10%), current rating (minimum 1.2A), DC resistance (100mOhm maximum), frequency characteristics (Q factor and self-resonant frequency), operating temperature range, and mounting configuration (through-hole axial).

Two substitute parts are identified:

Direct Substitute (ER1025-00KR): Matches all electrical specifications and physical form factor. Identical inductance, tolerance, current rating, DC resistance, Q factor, self-resonant frequency, and operating temperature range. Differs only in product status (active vs. obsolete) and packaging format.

Similar Substitute (SC30R15KT): Meets core electrical requirements with equivalent inductance, tolerance, DC resistance, Q factor, and self-resonant frequency. Current rating is higher (1.33A vs. 1.2A). Physical dimensions differ due to shielding implementation. Operating temperature maximum is reduced to 100°C. Shielding characteristic differs (shielded vs. unshielded).

Engineering Selection Recommendations

API Delevan ER1025-00KR is the primary substitute for direct replacement applications. This part maintains identical electrical specifications and physical dimensions while offering active product status and military-grade qualification (MIL-PRF-39010/08). Selection of this part eliminates obsolescence risk and provides equivalent performance across all specified parameters.

TE Connectivity SC30R15KT is suitable for applications where shielding is beneficial or required and where the reduced upper operating temperature limit (100°C vs. 125°C) is acceptable. The higher current rating (1.33A) provides additional margin. This part offers ROHS3 compliance, addressing environmental regulatory requirements. Physical size increase must be accommodated in board layout. The shielded construction may reduce electromagnetic interference in sensitive applications but is not electrically equivalent to the unshielded original design.

For new designs or applications requiring strict thermal performance to 125°C, the API Delevan ER1025-00KR is the appropriate selection. For applications with relaxed thermal requirements and environmental compliance mandates, the TE Connectivity SC30R15KT provides an alternative path.

Frequently Asked Questions (FAQ)

Q: Can SC30R15KT be used as a direct drop-in replacement for 9130-00?

A: SC30R15KT is electrically compatible but not a direct physical replacement. The shielded construction increases physical dimensions (0.165" diameter vs. 0.095"), requiring board layout modification. The operating temperature maximum is reduced to 100°C. Use only if board space permits and thermal requirements do not exceed 100°C.

Q: What is the difference between shielded and unshielded inductors in this application?

A: Shielding reduces electromagnetic field radiation and susceptibility to external fields. The 9130-00 is unshielded; SC30R15KT is shielded. Selection depends on circuit requirements. If the original design specified unshielded operation, shielding may alter circuit behavior.

Q: Is ER1025-00KR a complete equivalent to 9130-00?

A: Yes. ER1025-00KR matches all electrical parameters, physical dimensions, and operating characteristics. The primary difference is product status (active vs. obsolete) and packaging format (Tape & Reel vs. standard packaging). This part is the recommended substitute for direct replacement.

Q: What compliance differences exist between these parts?

A: The 9130-00 and ER1025-00KR are both RoHS non-compliant. SC30R15KT is ROHS3 compliant. For applications subject to RoHS requirements, SC30R15KT is the only compliant option among these three parts.

Q: Can these parts be used interchangeably in high-frequency applications?

A: All three parts share identical Q factor (38 @ 25MHz) and self-resonant frequency (600MHz) specifications. Electrical performance in high-frequency circuits is equivalent. Physical differences (shielding, size) may affect circuit layout and EMI characteristics but not fundamental frequency response.

Q: What is the packaging difference between ER1025-00KR and 9130-00?

A: ER1025-00KR is supplied in Tape & Reel format; 9130-00 packaging format is not specified in available data. Tape & Reel packaging is standard for active production parts and facilitates automated assembly processes.
