Substitute Part Grouping Explanation

Substitution of the Bourns 9310-04-RC is determined by strict equivalence across the following critical parameters:

• Inductance value: 330 nH with ±20% tolerance
• DC resistance: 90 mOhm maximum
• Current rating: minimum 1.4 A
• Q factor: 45 @ 25 MHz
• Self resonant frequency: 360 MHz
• Operating temperature range: minimum -55°C to 105°C
• Mounting configuration: through-hole axial
• Physical dimensions: 0.156" Dia x 0.375" L
• Shielding: unshielded
• Regulatory compliance: ROHS3 compliant

The API Delevan 1537R-04M meets all substitution criteria while offering improved current rating and extended upper operating temperature.

Parameter Comparison

Engineering Selection Recommendations

The API Delevan 1537R-04M is a direct functional equivalent to the obsolete Bourns 9310-04-RC. Both components maintain identical electrical specifications for inductance, tolerance, DC resistance, Q factor, and self-resonant frequency. The substitute part provides enhanced current rating (1.58 A versus 1.4 A) and extended operating temperature range (-55°C to 125°C versus -55°C to 105°C), offering improved thermal margin for system applications.

Both parts maintain ROHS3 compliance and are suitable for equivalent circuit implementations. The API Delevan component is currently in active production status, ensuring long-term availability and supply chain continuity compared to the obsolete Bourns part.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan 1537R-04M directly replace the Bourns 9310-04-RC in existing designs?

A: Yes. Both components share identical inductance (330 nH), tolerance (±20%), DC resistance (90 mOhm max), Q factor (45 @ 25 MHz), self-resonant frequency (360 MHz), and physical dimensions (0.156" Dia x 0.375" L). The through-hole axial mounting configuration and unshielded design are identical.

Q: What are the differences between these two parts?

A: The API Delevan 1537R-04M offers a higher current rating (1.58 A versus 1.4 A) and extended upper operating temperature (125°C versus 105°C). The Bourns part uses a drum core construction while the API Delevan uses molded construction. The API Delevan part is supplied in tape and reel packaging, whereas the Bourns part is supplied in bulk.

Q: Are there any thermal considerations when substituting these parts?

A: The API Delevan 1537R-04M supports operation to 125°C, providing 20°C additional thermal headroom compared to the Bourns 9310-04-RC. This extended range does not introduce thermal incompatibility; it provides additional design margin.

Q: Does the packaging format affect electrical performance?

A: No. Tape and reel packaging (API Delevan) versus bulk packaging (Bourns) affects only handling and assembly processes. Electrical characteristics and performance remain identical.

Q: Are both parts RoHS compliant?

A: Yes. Both the Bourns 9310-04-RC and API Delevan 1537R-04M are ROHS3 compliant, meeting current environmental and regulatory requirements.
