Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Bourns 9210-94 is determined by strict alignment of the following critical parameters:

• Inductance Value: Must be 240 µH with ±5% tolerance
• DC Resistance: Must not exceed 7.8Ohm maximum
• Current Rating: Must meet or exceed 101 mA minimum requirement
• Q Factor & Self Resonant Frequency: Must match 65 @ 790kHz and 5.9MHz respectively
• Mounting Configuration: Must be through-hole axial package
• Physical Dimensions: Must be 0.156" Dia x 0.375" L (3.96mm x 9.53mm)
• Shielding Type: Must be unshielded

The API Delevan 1537-94J meets all substitution criteria with identical inductance, tolerance, DC resistance, Q factor, self resonant frequency, mounting type, package configuration, and physical dimensions. The substitute part provides an increased current rating of 115 mA, offering improved headroom for the application.

Parameter Comparison

Engineering Selection Recommendations

The API Delevan 1537-94J is a direct functional substitute for the obsolete Bourns 9210-94. Both components share identical electrical specifications for inductance, tolerance, DC resistance, Q factor, and self resonant frequency. The substitute part maintains the same through-hole axial package configuration and physical dimensions, ensuring mechanical compatibility in existing PCB layouts.

The API Delevan 1537-94J offers an active product status, providing assured long-term availability and supply chain continuity compared to the obsolete Bourns part. Both components carry identical compliance certifications (RoHS non-compliant, REACH Unaffected, EAR99 classification, HTSUS 8504.50.8000).

The substitute part provides a higher current rating of 115 mA versus the original 101 mA specification, delivering additional design margin. The operating temperature range of the substitute extends to 105°C maximum, which is 20°C lower than the original part's 125°C upper limit. This temperature differential must be evaluated against specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan 1537-94J be used as a direct replacement for the Bourns 9210-94?

A: Yes. Both components share identical inductance (240 µH), tolerance (±5%), DC resistance (7.8Ohm Max), Q factor (65 @ 790kHz), self resonant frequency (5.9MHz), mounting type (through-hole), package configuration (axial), and physical dimensions (0.156" Dia x 0.375" L). The substitute part is electrically and mechanically compatible.

Q: What are the differences between these two parts?

A: The primary differences are: (1) Product status—the Bourns 9210-94 is obsolete while the API Delevan 1537-94J is active; (2) Current rating—the substitute provides 115 mA versus 101 mA; (3) Core material—phenolic versus iron; (4) Operating temperature maximum—105°C versus 125°C; (5) Packaging—the substitute is supplied in Tape & Reel format.

Q: Does the lower maximum operating temperature of the substitute part affect compatibility?

A: The API Delevan 1537-94J operates to 105°C maximum, compared to 125°C for the original part. Compatibility depends on the specific application's thermal requirements. If the design operates below 105°C, the substitute is suitable. If sustained operation above 105°C is required, the temperature specification must be evaluated against application conditions.

Q: Are there any compliance or regulatory differences?

A: Both components carry identical compliance designations: RoHS non-compliant, REACH Unaffected, ECCN EAR99, and HTSUS 8504.50.8000. No compliance differences exist between the parts.

Q: What is the significance of the core material difference?

A: The Bourns 9210-94 uses a phenolic core while the API Delevan 1537-94J uses an iron core. Despite this material difference, both components deliver identical electrical performance at the specified test frequency (790 kHz) and maintain the same inductance value, tolerance, Q factor, and self resonant frequency.
