Engineering Selection Recommendations

All listed API Delevan parts are active products and provide direct electrical equivalence to the obsolete Bourns 9230-14. Selection among substitute parts should be based on the following criteria:

For RoHS3 compliance requirements: API Delevan 1025R-14K is the only substitute offering ROHS3 compliance.

For extended temperature operation: API Delevan 1025-14K, 1025R-14K, and ER1025-14KR support the extended operating range of -55°C to 125°C, compared to the original -55°C to 105°C specification.

For higher current capacity: API Delevan 1025-14K and 1025R-14K are rated for 550 mA, exceeding the original 495 mA rating. API Delevan ER1025-14KM, ER1025-14KP, and ER1025-14KR are rated for 545 mA.

For packaging requirements: Selection depends on assembly process compatibility. Cut Tape (CT) format is available via 1025-14K, Bulk format via 1025R-14K, and Tape & Reel (TR) format via ER1025-14KM, ER1025-14KP, and ER1025-14KR.

For military specifications: API Delevan 1025-14K conforms to MIL-PRF-M15305 and MS75083. API Delevan ER1025-14KR conforms to MIL-PRF-39010/08.

Frequently Asked Questions (FAQ)

Q: Can API Delevan parts directly replace the Bourns 9230-14 in existing designs?

A: Yes. All listed API Delevan parts maintain identical inductance (560 nH), tolerance (±10%), DC resistance (500 mOhm Max), Q factor (30 @ 25 MHz), self-resonant frequency (300 MHz), physical dimensions (0.095" Dia x 0.250" L), core material (Phenolic), and shielding characteristics (Unshielded). Through-hole axial mounting is preserved across all substitutes.

Q: What is the difference between the ER1025 series variants (ER1025-14KM, ER1025-14KP, ER1025-14KR)?

A: All three ER1025 variants share identical electrical specifications and current ratings (545 mA). The primary differences are packaging format (all supplied in Tape & Reel), operating temperature range (ER1025-14KM and ER1025-14KP: -55°C to 105°C; ER1025-14KR: -55°C to 125°C), and military compliance (ER1025-14KR conforms to MIL-PRF-39010/08).

Q: Which substitute offers the best compliance profile?

A: API Delevan 1025R-14K is ROHS3 compliant, whereas all other substitutes are RoHS non-compliant. Selection should align with end-product compliance requirements.

Q: Are there current rating differences between substitutes?

A: Yes. The original Bourns 9230-14 is rated for 495 mA. API Delevan 1025-14K and 1025R-14K are rated for 550 mA. API Delevan ER1025-14KM, ER1025-14KP, and ER1025-14KR are rated for 545 mA. All substitutes exceed or match the original current specification.

Q: What packaging formats are available?

A: Cut Tape (CT) via 1025-14K, Bulk via 1025R-14K, and Tape & Reel (TR) via ER1025-14KM, ER1025-14KP, and ER1025-14KR. Selection depends on assembly process and volume requirements.

Q: Do any substitutes support extended temperature operation?

A: Yes. API Delevan 1025-14K, 1025R-14K, and ER1025-14KR support -55°C to 125°C operation, compared to the original -55°C to 105°C range. API Delevan ER1025-14KM and ER1025-14KP maintain the original -55°C to 105°C range.
