Bourns 9310-16 Equivalent & Substitute Parts

Part Overview

The Bourns 9310-16 is a 1.5 µH unshielded drum core wirewound inductor rated for 600 mA with a maximum DC resistance of 500mOhm. This through-hole axial component operates across the temperature range of -55°C to 105°C and features a ferrite core construction. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. API Delevan Inc. manufactures several direct functional equivalents that maintain electrical and mechanical compatibility while offering active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Bourns 9310-16 is determined by strict electrical and mechanical parameter matching:

Primary Substitution Criteria:

• Inductance value: 1.5 µH with ±10% tolerance
• DC resistance: 500mOhm maximum
• Current rating: minimum 600 mA
• Shielding: unshielded configuration
• Package: axial through-hole
• Physical dimensions: 0.156" Dia x 0.375" L (3.96mm x 9.53mm)
• Q factor: 33 @ 7.9MHz
• Self resonant frequency: 160MHz

All substitute parts listed maintain these core electrical specifications. Variations in core material (phenolic vs. ferrite), inductor type (molded vs. drum core), and packaging format (cut tape vs. tape & reel) do not affect functional equivalence when electrical parameters remain constant. Temperature range extensions in certain substitutes provide additional operational flexibility without compromising compatibility.

Parameter Comparison

Engineering Selection Recommendations

All listed API Delevan substitutes maintain full electrical and mechanical compatibility with the Bourns 9310-16. Selection among the four equivalent parts should be based on the following factors:

Product Status: All substitute parts carry active product status, ensuring long-term availability and supply chain continuity compared to the obsolete Bourns 9310-16.

Current Rating Headroom: The API Delevan 1537-16K offers 670 mA current rating, providing 70 mA additional capacity over the original 600 mA specification. This margin is available for applications requiring enhanced current handling without exceeding DC resistance limits.

Temperature Range: API Delevan ER1537-16KR and 1537-16K extend the upper operating temperature to 125°C, compared to the original 105°C maximum. This extended range accommodates higher ambient or component-level thermal environments.

Packaging Format: Cut tape (CT) packaging via the 1537-16K variant suits lower-volume manual assembly operations. Tape & reel (TR) formats (ER1537-16KM, ER1537-16KP, ER1537-16KR) are optimized for automated pick-and-place manufacturing processes.

Compliance and Certifications: All substitutes maintain identical RoHS non-compliance status, REACH unaffected classification, and EAR99 ECCN designation as the original part. Military-grade variants (1537-16K per MIL-PRF-M15305/MS18130 and ER1537-16KR per MIL-PRF-39010/06) are available for applications requiring military specification compliance.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan 1537-16K be used as a direct replacement for the Bourns 9310-16?

A: Yes. The 1537-16K maintains identical inductance (1.5 µH), tolerance (±10%), DC resistance (500mOhm max), Q factor (33 @ 7.9MHz), self resonant frequency (160MHz), and physical dimensions (0.156" Dia x 0.375" L). The 670 mA current rating exceeds the original 600 mA specification, providing additional operational margin. The extended temperature range (-55°C to 125°C) is compatible with applications designed for the original -55°C to 105°C range.

Q: What is the difference between the ER1537-16KM, ER1537-16KP, and ER1537-16KR variants?

A: All three ER1537 variants share identical electrical specifications (1.5 µH, 600 mA, 500mOhm DCR). The primary differences are packaging format (all use tape & reel) and temperature rating. ER1537-16KM and ER1537-16KP operate to 105°C, matching the original part. ER1537-16KR extends to 125°C and carries military specification MIL-PRF-39010/06 compliance. Selection depends on temperature requirements and military qualification needs.

Q: Are there any mechanical compatibility concerns when substituting these parts?

A: No. All substitute parts maintain the identical axial through-hole package configuration and physical dimensions (0.156" Dia x 0.375" L / 3.96mm x 9.53mm). PCB footprints, lead spacing, and mounting procedures remain unchanged. No circuit board redesign is required.

Q: How do core material differences (ferrite vs. phenolic) affect substitution?

A: Core material differences do not affect electrical equivalence when inductance, tolerance, Q factor, and self resonant frequency specifications are identical. The Bourns 9310-16 uses ferrite core construction, while API Delevan substitutes employ phenolic cores. Both materials deliver the specified electrical performance within the stated operating parameters.

Q: Which substitute part should be selected for automated assembly?

A: All three ER1537 variants (ER1537-16KM, ER1537-16KP, ER1537-16KR) are supplied in tape & reel (TR) packaging, optimized for automated pick-and-place equipment. The 1537-16K is supplied in cut tape (CT) format, suitable for manual assembly or lower-volume production runs.

Q: Do the substitute parts meet the same compliance standards as the original?

A: Yes. All substitute parts maintain RoHS non-compliant status, REACH unaffected classification, and EAR99 ECCN designation identical to the Bourns 9310-16. Military-grade options (1537-16K and ER1537-16KR) provide additional MIL-PRF compliance certifications for applications requiring military specification qualification.
