Bourns 9310-00-RC 150nH Axial Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 9310-00-RC is a 150nH unshielded drum core wirewound inductor rated for 2.45A continuous current with 30mOhm maximum DC resistance. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and production continuity. The part operates across the temperature range of -55°C to 105°C and is ROHS3 compliant.

Engineering Selection Recommendations

API Delevan 1537R-00M (Direct Substitute - Recommended)

The 1537R-00M is the primary equivalent for the obsolete Bourns 9310-00-RC. This part maintains all critical electrical specifications while offering improved current rating (2.74A vs. 2.45A) and extended operating temperature range (-55°C to 125°C vs. -55°C to 105°C). The part is active in production and ROHS3 compliant. Packaging is supplied in Tape & Reel format, suitable for automated assembly processes.

API Delevan 1537-00M (Alternative Substitute)

The 1537-00M provides identical electrical performance to the 1537R-00M with the same current rating and temperature range. This part is supplied in Cut Tape format and is active in production. However, this part is RoHS non-compliant and carries military specifications (MIL-PRF-M15305, MS18130). Selection of this part should be based on specific application requirements and regulatory compliance needs.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan 1537R-00M directly replace the Bourns 9310-00-RC?

A: Yes. The 1537R-00M meets all electrical and mechanical specifications of the 9310-00-RC. The higher current rating (2.74A vs. 2.45A) and extended temperature range provide additional design margin. Physical dimensions and mounting type are identical.

Q: What is the difference between the 1537R-00M and 1537-00M?

A: Both parts have identical electrical specifications. The primary differences are packaging format (Tape & Reel vs. Cut Tape) and RoHS compliance status. The 1537R-00M is ROHS3 compliant; the 1537-00M is not. The 1537-00M carries military specifications.

Q: Does core material affect substitution compatibility?

A: No. The Bourns 9310-00-RC uses ferrite core material while the API Delevan substitutes use phenolic core material. Both materials deliver the specified electrical performance within the defined parameters. Core material selection does not impact compatibility for this application.

Q: Are there any temperature range limitations when substituting?

A: The substitute parts operate at higher maximum temperatures (125°C vs. 105°C). This provides additional thermal margin and does not create compatibility issues. Applications operating within the original -55°C to 105°C range will function identically with either part.

Q: What packaging considerations apply to these substitutes?

A: The 1537R-00M is supplied in Tape & Reel format for automated pick-and-place assembly. The 1537-00M is supplied in Cut Tape format for manual or semi-automated assembly. Both formats are compatible with standard through-hole mounting processes. Selection depends on production assembly method and volume requirements.
