Equivalent & Substitute Parts for 9310-02-RC

Part Overview

The Bourns 9310-02-RC is a 220 nH unshielded drum core wirewound inductor rated for 1.9 A with a maximum DC resistance of 55 mOhm. This through-hole axial component operates across a temperature range of -55°C to 105°C and is classified as obsolete. Due to its obsolete status, equivalent substitute parts from active product lines are necessary to maintain design continuity and ensure ongoing component availability for production and repair applications.

Substitute Part Grouping Explanation

Substitution for the 9310-02-RC is determined by strict equivalence across the following critical parameters: inductance value (220 nH), tolerance (±20%), DC resistance (55 mOhm maximum), shielding configuration (unshielded), Q factor (50 @ 25 MHz), self-resonant frequency (450 MHz), mounting type (through hole), package style (axial), and physical dimensions (0.156" Dia x 0.375" L).

The API Delevan 1537R-02M and 1537-02M meet these electrical and mechanical requirements. Both parts maintain identical inductance, tolerance, DC resistance, Q factor, and self-resonant frequency specifications. The current rating of 2.02 A in the substitute parts exceeds the 1.9 A requirement of the original part, providing additional design margin. Physical dimensions and mounting characteristics are identical, ensuring direct mechanical compatibility in through-hole applications.

Parameter Comparison

Engineering Selection Recommendations

Both API Delevan substitute parts are active products with current manufacturing support, addressing the obsolescence of the original 9310-02-RC. The 1537R-02M is the preferred substitute, offering ROHS3 compliance matching the original part's regulatory status and providing extended operating temperature capability to 125°C. The 1537-02M is functionally equivalent but carries RoHS non-compliance status, making it suitable only for applications where RoHS compliance is not required.

Selection between the two API Delevan options depends on regulatory and compliance requirements of the end application. For designs requiring RoHS3 compliance, the 1537R-02M is the appropriate choice. Both parts deliver superior current handling at 2.02 A compared to the original 1.9 A specification, with identical electrical performance across all critical parameters.

Frequently Asked Questions (FAQ)

Q: Can the 1537R-02M and 1537-02M be used interchangeably with the 9310-02-RC?

A: Both API Delevan parts meet the electrical and mechanical specifications of the 9310-02-RC. Selection depends on compliance requirements. The 1537R-02M maintains ROHS3 compliance; the 1537-02M does not.

Q: What is the impact of the higher current rating in the substitute parts?

A: The 2.02 A rating in both substitute parts exceeds the original 1.9 A requirement. This provides additional design margin and does not create compatibility issues in circuits designed for the original part.

Q: Are the physical dimensions identical?

A: Yes. Both substitute parts maintain the same axial package dimensions of 0.156" diameter by 0.375" length (3.96mm x 9.53mm), ensuring direct mechanical compatibility in through-hole PCB layouts.

Q: Does the extended temperature range of the substitutes affect compatibility?

A: No. The substitute parts operate from -55°C to 125°C, which encompasses the original part's -55°C to 105°C range. This extended capability does not create compatibility constraints.

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

A: Both 1537R-02M and 1537-02M are supplied in Tape & Reel (TR) packaging for automated assembly processes.
