Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1025R-92K are identified based on strict equivalence of the following critical parameters:

• Inductance Value: 1 mH (exact match required)
• Inductance Tolerance: ±10% (exact match required)
• DC Resistance: 72 Ohm Max (exact match required)
• Q @ Frequency: 30 @ 790 kHz (exact match required)
• Self Resonant Frequency: 3.4 MHz (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Axial (exact match required)
• Physical Dimensions: 0.095" Dia x 0.250" L (exact match required)
• Core Material: Ferrite (exact match required)
• Shielding: Unshielded (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

The 9230-92-RC from Bourns Inc. meets all critical electrical and mechanical parameters. Variations in current rating and maximum operating temperature do not disqualify substitution when the application requirements fall within the substitute part's specifications.

Engineering Selection Recommendations

Primary Part: 1025R-92K

The 1025R-92K remains the specified component when the application design is validated against API Delevan Inc. specifications and the -55°C to 105°C operating temperature range is confirmed as adequate.

Substitute Part: 9230-92-RC

The 9230-92-RC from Bourns Inc. is electrically and mechanically equivalent for applications where:

• The circuit design operates within the 28 mA current specification of the original part, or the application current does not exceed 38 mA
• The operating temperature range does not exceed 105°C, or the extended range to 125°C provides additional design margin
• PCB layout and mechanical assembly accommodate the identical axial through-hole package dimensions

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent substitution.

Frequently Asked Questions (FAQ)

Q: Can the 9230-92-RC replace the 1025R-92K in all applications?

A: The 9230-92-RC is electrically and mechanically equivalent when the application current requirement does not exceed 28 mA (the original part rating). If the circuit design requires current capacity between 28 mA and 38 mA, the 9230-92-RC provides additional margin. Verify that the operating temperature range of -55°C to 105°C is sufficient for your application; the 9230-92-RC extends to 125°C.

Q: Are the physical dimensions identical?

A: Yes. Both the 1025R-92K and 9230-92-RC are 0.095" diameter by 0.250" length (2.41mm x 6.35mm) in axial through-hole configuration. PCB footprint and mechanical clearance requirements are identical.

Q: What is the difference in current rating between these parts?

A: The 1025R-92K is rated for 28 mA, while the 9230-92-RC is rated for 38 mA. The higher rating on the substitute part does not affect compatibility; it indicates greater current capacity. Use the substitute only if your application current does not exceed the original 28 mA specification, or if the design can accommodate the higher rating.

Q: Do both parts have the same inductance tolerance?

A: Yes. Both parts are specified at 1 mH with ±10% tolerance and are tested at 790 kHz. The Q factor of 30 at 790 kHz and self-resonant frequency of 3.4 MHz are identical.

Q: Are there compliance differences between these parts?

A: No. Both the 1025R-92K and 9230-92-RC are ROHS3 compliant and REACH unaffected. Regulatory compliance is equivalent.
