Equivalent & Substitute Parts for 9250-334-RC

Part Overview

The Bourns 9250-334-RC is a 330 µH shielded drum core wirewound inductor rated for 110 mA with a maximum DC resistance of 6.4 Ohm. This through-hole axial component operates across -55°C to 105°C and is designed for applications requiring fixed inductance with ferrite core shielding. The 9250-334-RC is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production support.

Engineering Selection Recommendations

Primary Recommendation: 9250A-334-RC

The Bourns 9250A-334-RC is the direct successor to the obsolete 9250-334-RC. Both are manufactured by Bourns Inc. and share identical electrical specifications and physical dimensions. The 9250A-334-RC is currently in active production status with higher inventory availability (2270 units). The primary advantage is an extended operating temperature range of -55°C to 125°C compared to the original -55°C to 105°C. Both parts maintain ROHS3 compliance. The 9250A-334-RC uses molded construction versus the original drum core design, but electrical performance remains equivalent across all specified parameters.

Secondary Recommendations: ER1641-334KM, ER1641-334KP, ER1641-334KR

The API Delevan ER1641 series parts (ER1641-334KM, ER1641-334KP, ER1641-334KR) provide functional equivalence with identical electrical specifications and physical dimensions. These parts are active production items with good inventory availability. The primary consideration is RoHS compliance status: these parts are RoHS non-compliant, whereas the main part and 9250A-334-RC are ROHS3 compliant. Selection of ER1641 variants should be based on application regulatory requirements and packaging format needs (Tape & Reel format available).

Frequently Asked Questions (FAQ)

Q: Can the 9250A-334-RC directly replace the obsolete 9250-334-RC?

A: Yes. The 9250A-334-RC meets all electrical and mechanical specifications of the 9250-334-RC. Both parts deliver 330 µH inductance, 110 mA current rating, 6.4 Ohm maximum DC resistance, and identical physical dimensions. The 9250A-334-RC is the active production equivalent and is recommended for new designs.

Q: What is the difference between the 9250-334-RC and 9250A-334-RC construction?

A: The 9250-334-RC uses drum core wirewound construction, while the 9250A-334-RC uses molded construction. Despite this structural difference, both parts deliver identical electrical performance across all specified parameters including inductance, Q factor, and self-resonant frequency.

Q: Are the ER1641 series parts suitable for RoHS-regulated applications?

A: No. The ER1641-334KM, ER1641-334KP, and ER1641-334KR are RoHS non-compliant. For applications requiring RoHS compliance, use the 9250A-334-RC (ROHS3 compliant) or the original 9250-334-RC (ROHS3 compliant).

Q: What packaging formats are available for these substitute parts?

A: The 9250A-334-RC is available in Bulk packaging. The ER1641 series parts (ER1641-334KM, ER1641-334KP, ER1641-334KR) are available in Tape & Reel (TR) format. Packaging selection depends on production volume and assembly process requirements.

Q: Do all substitute parts operate across the same temperature range?

A: No. The 9250-334-RC and ER1641 series parts operate from -55°C to 105°C. The 9250A-334-RC extends this range to -55°C to 125°C. Application temperature requirements should guide part selection.

Q: Are there differences in current saturation specifications?

A: The 9250-334-RC specifies a saturation current (Isat) of 65 mA. The ER1641 series parts do not provide saturation current specifications in the available data. The 9250A-334-RC also specifies 65 mA saturation current, matching the original part.
