Bourns 9210-54 Equivalent & Substitute Parts

Part Overview

The Bourns 9210-54 is a 36 µH unshielded molded inductor rated for 180 mA with a maximum DC resistance of 2.5Ohm, designed for through-hole axial mounting. This component operates across a temperature range of -55°C to 105°C and is characterized as obsolete. Due to its obsolete status, identifying functionally equivalent substitute parts is essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Bourns 9210-54 is determined by strict alignment of the following electrical and mechanical parameters:

• Inductance value: 36 µH (exact match required)
• Inductance tolerance: ±5% (exact match required)
• DC resistance: 2.5Ohm Max (exact match required)
• Q factor @ 2.5MHz: 60 (exact match required)
• Self resonant frequency: 15.5MHz (exact match required)
• Operating temperature range: -55°C ~ 105°C (exact match required)
• Mounting type: Through Hole (exact match required)
• Package / Case: Axial (exact match required)
• Physical dimensions: 0.156" Dia x 0.375" L (exact match required)
• Shielding: Unshielded (exact match required)
• Type: Molded (exact match required)

The API Delevan 1537-54J meets all substitution criteria. While the core material differs (Iron vs. Ferrite) and the current rating is higher (202 mA vs. 180 mA), all critical electrical and mechanical parameters align with the original specification.

Parameter Comparison

Engineering Selection Recommendations

The API Delevan 1537-54J is a direct substitute for the obsolete Bourns 9210-54. The substitute part is currently in active production status, ensuring long-term availability and supply chain stability. Both components share identical electrical performance characteristics, physical dimensions, and compliance certifications. The higher current rating of the 1537-54J (202 mA vs. 180 mA) provides additional design margin without compromising performance in applications designed for the original 180 mA specification. Both parts maintain RoHS non-compliant and REACH Unaffected status with identical ECCN and HTSUS classifications.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan 1537-54J be used as a direct replacement for the Bourns 9210-54?

A: Yes. The 1537-54J meets all electrical and mechanical specifications of the 9210-54, including inductance value, tolerance, DC resistance, Q factor, self-resonant frequency, operating temperature range, and physical dimensions. The substitute is pin-compatible and functionally equivalent.

Q: What is the difference in core material between these parts?

A: The Bourns 9210-54 uses a ferrite core, while the API Delevan 1537-54J uses an iron core. Both materials deliver the specified electrical performance parameters. The core material difference does not affect substitution eligibility when all electrical characteristics remain identical.

Q: Why is the current rating different between the two parts?

A: The API Delevan 1537-54J has a higher current rating (202 mA) compared to the Bourns 9210-54 (180 mA). This difference reflects the manufacturer's design margin and does not prevent substitution. Applications designed for 180 mA operation will function within the 202 mA rating of the substitute part.

Q: Are there packaging differences between these inductors?

A: Both parts use identical through-hole axial packaging with the same physical dimensions (0.156" Dia x 0.375" L). The Bourns 9210-54 is supplied as loose components, while the API Delevan 1537-54J is available in Tape & Reel packaging. Both formats are compatible with standard PCB assembly processes.

Q: What is the product status difference, and does it affect substitution?

A: The Bourns 9210-54 is obsolete, while the API Delevan 1537-54J is active. The active status of the substitute ensures continued availability and manufacturing support, making it the preferred choice for new designs and ongoing production requirements.
