Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1641-152K are qualified based on the following critical parameters that determine functional interchangeability:

Electrical Parameters (Must Match):

• Inductance value: 1.5 µH
• Inductance tolerance: ±10%
• DC resistance: 120mOhm maximum
• Current rating: minimum 815 mA (substitute may be equal or lower, but not exceed main part saturation current)
• Shielding: Shielded configuration required
• Q factor at test frequency: 44 @ 7.9 MHz
• Self-resonant frequency: 115 MHz

Mechanical Parameters (Must Match):

• Mounting type: Through Hole
• Package case: Axial
• Physical dimensions: 0.162" Dia × 0.410" L (4.11mm × 10.41mm)

Environmental Parameters (Must Match or Exceed):

• Operating temperature range: minimum -55°C to 105°C

The 9250A-152-RC from Bourns Inc. qualifies as a substitute because it meets all critical electrical and mechanical parameters within the allowed tolerances, despite differences in core material (Ferrite vs. Iron) and packaging format (Bulk vs. Tape & Reel).

Parameter Comparison

Engineering Selection Recommendations

1641-152K (API Delevan Inc.) - Primary Selection:

• Active product status with established supply chain
• Military specification compliance (MIL-PRF-M15305, MS75088)
• RoHS non-compliant status; suitable for legacy or non-regulated applications
• Tape & Reel packaging for automated assembly processes
• Iron core construction

9250A-152-RC (Bourns Inc.) - Substitute Selection:

• Active product status with confirmed availability
• RoHS3 compliant; suitable for applications requiring environmental compliance
• Bulk packaging; requires manual handling or repackaging for automated assembly
• Ferrite core construction with extended operating temperature range (-55°C to 125°C)
• Electrical performance equivalent within specified tolerances

Selection between these parts depends on compliance requirements (RoHS status), packaging automation needs (Tape & Reel vs. Bulk), and supply chain considerations. Both parts satisfy the core electrical and mechanical requirements for 1.5 µH shielded axial inductor applications.

Frequently Asked Questions (FAQ)

Q: Can the 9250A-152-RC replace the 1641-152K in all applications?

A: The 9250A-152-RC is electrically and mechanically compatible with the 1641-152K based on matching inductance, tolerance, DC resistance, current rating, shielding, and physical dimensions. The substitute has a lower saturation current (815 mA vs. 835 mA) and extended temperature range (-55°C to 125°C vs. -55°C to 105°C). Verify that the 20 mA reduction in current rating and RoHS3 compliance status align with your application requirements.

Q: What is the significance of the current rating difference (835 mA vs. 815 mA)?

A: The 1641-152K has a maximum current rating of 835 mA, while the 9250A-152-RC is rated at 815 mA. This 20 mA difference represents a 2.4% reduction. If your circuit operates near the upper current limit of the 1641-152K, the substitute may not be suitable. For applications operating below 815 mA, this difference is not a limiting factor.

Q: Are there packaging differences between these parts?

A: Yes. The 1641-152K is supplied in Tape & Reel (TR) format, suitable for automated pick-and-place assembly. The 9250A-152-RC is supplied in Bulk packaging, requiring manual handling or repackaging for automated processes. Both parts have identical axial physical dimensions (0.162" Dia × 0.410" L).

Q: What is the difference between Iron and Ferrite core materials?

A: The 1641-152K uses an Iron core, while the 9250A-152-RC uses a Ferrite core. Both achieve the same inductance value (1.5 µH) and DC resistance (120mOhm max) at the specified test frequency (7.9 MHz). Core material differences may affect frequency response characteristics outside the specified test parameters, but within the provided electrical specifications, both parts are equivalent.

Q: Does RoHS compliance affect substitution eligibility?

A: The 1641-152K is RoHS non-compliant, while the 9250A-152-RC is RoHS3 compliant. If your application or regulatory environment requires RoHS compliance, the 9250A-152-RC is the appropriate selection. If RoHS compliance is not required, both parts are functionally equivalent.

Q: Can I use the 9250A-152-RC in applications requiring military specifications?

A: The 1641-152K is specified to MIL-PRF-M15305 and MS75088 military standards. The 9250A-152-RC is specified to the Bourns 9250A series standard. If your application explicitly requires military specification compliance, the 1641-152K is the required selection. The 9250A-152-RC does not carry military specification designation.
