Equivalent & Substitute Parts for Bourns 9250-563-RC

Part Overview

The Bourns 9250-563-RC is a 56 µH shielded drum core wirewound inductor rated for 190 mA with a maximum DC resistance of 2.23 Ohm. This through-hole axial component operates across -55°C to 105°C and is classified as obsolete. Due to its obsolete status, equivalent substitute parts from both Bourns and API Delevan are available to maintain design continuity and ensure supply chain reliability.

Substitute Part Grouping Explanation

Substitution eligibility is determined by matching the following critical parameters: inductance value (56 µH), tolerance (±10%), current rating (190 mA), DC resistance (2.23 Ohm max), shielding configuration, Q factor (50 @ 2.5 MHz), self-resonant frequency (25 MHz), mounting type (through hole), and package format (axial). All substitute parts listed maintain these electrical and mechanical specifications.

The substitute parts are grouped into two categories:

Direct Manufacturer Substitute: Bourns 9250A-563-RC maintains identical electrical performance with an extended operating temperature range (-55°C to 125°C) and active product status.

Cross-Manufacturer Substitutes: API Delevan ER1641 series parts (ER1641-563KM, ER1641-563KP, ER1641-563KR) provide equivalent electrical characteristics with variations in shielding configuration and regulatory compliance.

Engineering Selection Recommendations

Bourns 9250A-563-RC is the primary substitute for the obsolete 9250-563-RC. Both parts are manufactured by Bourns, maintain ROHS3 compliance, and deliver identical electrical specifications. The 9250A-563-RC offers an extended operating temperature range to 125°C and holds active product status, ensuring long-term availability and supply chain stability.

API Delevan ER1641-563KM and ER1641-563KP are functionally equivalent shielded alternatives with active status. These parts are available in tape and reel packaging. However, both are RoHS non-compliant, which may restrict use in applications requiring RoHS certification.

API Delevan ER1641-563KR provides electrical equivalence but features an unshielded configuration. This part is suitable only for applications where electromagnetic shielding is not required. Like other ER1641 variants, it is RoHS non-compliant.

For applications requiring RoHS compliance and shielding, Bourns 9250A-563-RC is the recommended selection. For applications without RoHS requirements, API Delevan ER1641-563KM or ER1641-563KP provide cost-effective alternatives with active product status.

Frequently Asked Questions (FAQ)

Q: Can the Bourns 9250A-563-RC directly replace the obsolete 9250-563-RC?

A: Yes. The 9250A-563-RC maintains all critical electrical parameters: 56 µH inductance, 190 mA current rating, 2.23 Ohm DC resistance, shielded configuration, and identical physical dimensions. The extended operating temperature range (-55°C to 125°C) provides additional thermal margin. Both parts are ROHS3 compliant.

Q: What is the difference between the ER1641-563KM/KP and ER1641-563KR?

A: ER1641-563KM and ER1641-563KP are shielded inductors matching the original 9250-563-RC shielding specification. ER1641-563KR is unshielded. All three maintain identical inductance, current rating, and DC resistance. Selection depends on whether electromagnetic shielding is required in your circuit.

Q: Are API Delevan ER1641 parts suitable for RoHS-regulated applications?

A: No. All ER1641 variants listed are RoHS non-compliant. For applications requiring RoHS certification, use Bourns 9250A-563-RC, which is ROHS3 compliant.

Q: What packaging formats are available for these substitutes?

A: Bourns 9250A-563-RC is supplied in bulk packaging. API Delevan ER1641 series parts are supplied in tape and reel (TR) format. Confirm packaging requirements with your procurement process before ordering.

Q: Do all substitute parts have the same physical dimensions?

A: Yes. All listed parts share identical axial package dimensions: 0.162" diameter x 0.410" length (4.11mm x 10.41mm). They are mechanically interchangeable on through-hole PCB layouts.

Q: What is the saturation current specification for the substitute parts?

A: Bourns 9250A-563-RC specifies 160 mA saturation current, matching the original 9250-563-RC. API Delevan ER1641 series parts do not provide saturation current specifications in the available data.
