Bourns 9310-07 560nH Inductor: Equivalent & Substitute Parts

Part Overview

The Bourns 9310-07 is a 560 nH unshielded drum core wirewound inductor rated for 1.22 A continuous current with 135 mOhm maximum DC resistance. This through-hole axial component operates across -55°C to 105°C and is designed for applications requiring low inductance values with controlled impedance characteristics at high frequencies.

The 9310-07 series is classified as obsolete. Identifying qualified substitute components ensures design continuity and supply chain reliability for legacy system maintenance and new production alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the Bourns 9310-07 must satisfy the following electrical and mechanical criteria:

• Inductance Value: 560 nH ±10% tolerance
• Current Rating: Minimum 1.22 A (substitutes rated ≥1.22 A are acceptable)
• DC Resistance: Maximum 135 mOhm
• Q Factor: 50 @ 25 MHz
• Self Resonant Frequency: 280 MHz
• Operating Temperature: Minimum -55°C to 105°C range
• Mounting & Package: Through-hole axial configuration
• Physical Dimensions: 0.156" Dia × 0.375" L (3.96mm × 9.53mm)
• Shielding: Unshielded

The API Delevan 1537-07K and 1537R-07K meet all specified electrical parameters. Both components use molded construction with phenolic cores instead of the original drum core design, but deliver equivalent electrical performance at the specified test frequency and operating conditions.

Parameter Comparison

Engineering Selection Recommendations

API Delevan 1537R-07K is the preferred substitute for new designs and production transitions. This component maintains all electrical specifications of the original Bourns 9310-07 while offering ROHS3 compliance and active product status. The extended operating temperature range (-55°C to 125°C) provides additional thermal margin beyond the original specification.

API Delevan 1537-07K serves as an alternative substitute with identical electrical performance and physical compatibility. This variant carries non-compliant RoHS status and should be evaluated against regulatory requirements for the target application.

Both substitutes deliver equivalent electrical performance at the specified inductance, current rating, DC resistance, and frequency characteristics. The transition from drum core to molded construction does not affect the electrical parameters within the specified operating envelope.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan 1537-07K or 1537R-07K be used as direct replacements for the Bourns 9310-07?

A: Yes. Both components meet all specified electrical parameters: 560 nH inductance, 1.22 A minimum current rating (both rated 1.29 A), 135 mOhm maximum DC resistance, and identical frequency characteristics. Physical dimensions and axial through-hole mounting are identical, enabling direct PCB substitution.

Q: What is the difference between the 1537-07K and 1537R-07K?

A: The primary difference is RoHS compliance status. The 1537R-07K is ROHS3 compliant, while the 1537-07K is non-compliant. Both deliver identical electrical performance and physical compatibility. Selection depends on regulatory requirements for the target application.

Q: Does the change from drum core to molded construction affect circuit performance?

A: No. Both construction types deliver the specified electrical parameters at the test frequency (25 MHz) and within the operating temperature range. The Q factor (50 @ 25 MHz) and self-resonant frequency (280 MHz) are identical across all three components.

Q: Are there temperature range considerations when substituting?

A: The API Delevan substitutes support -55°C to 125°C operation, exceeding the original -55°C to 105°C specification. This provides additional thermal margin and is compatible with applications designed for the original component's temperature range.

Q: What packaging formats are available for the substitute parts?

A: The API Delevan 1537-07K and 1537R-07K are supplied in Tape & Reel (TR) packaging. Verify packaging compatibility with assembly equipment and procurement workflows before finalizing component selection.
