Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IMC1812RW100J are qualified based on the following electrical and mechanical parameters:

• Inductance value: 10 µH (exact match required)
• Tolerance: ±5% (exact match required)
• Current rating: 250 mA (exact match required)
• DC resistance: 1.6Ω maximum (exact match required)
• Package: 1812 (4532 Metric) surface mount (exact match required)
• Shielding: Unshielded (exact match required)
• Q factor and self-resonant frequency: 50 @ 2.52MHz and 20MHz respectively (exact match required)

Both identified substitutes meet all critical electrical specifications and physical package requirements, ensuring direct compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All three inductors meet identical electrical and mechanical specifications for the 10 µH, 250 mA application. Selection between parts should be based on the following factors:

CM453232-100JL (Bourns) is ROHS3 compliant with MSL 1 rating and REACH unaffected status, providing regulatory compliance advantages and unlimited moisture exposure tolerance during storage and handling.

PM1812-100J-RC (Bourns) is ROHS3 compliant and REACH unaffected but carries MSL 3 rating, requiring controlled moisture exposure (168 hours maximum) during storage and assembly processes.

IMC1812RW100J (Vishay Dale) is RoHS non-compliant and REACH affected, with MSL 1 rating. This part remains suitable for applications without regulatory compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can CM453232-100JL or PM1812-100J-RC be used as direct replacements for IMC1812RW100J?

A: Yes. Both Bourns inductors match all critical electrical parameters (10 µH inductance, 250 mA current rating, 1.6Ω DC resistance) and physical package specifications (1812 surface mount). They are electrically and mechanically interchangeable.

Q: What is the difference between CM453232-100JL and PM1812-100J-RC?

A: Both parts are electrically identical. The primary differences are regulatory compliance (both ROHS3 and REACH unaffected) and moisture sensitivity. CM453232-100JL has MSL 1 (unlimited moisture exposure), while PM1812-100J-RC has MSL 3 (168-hour maximum exposure). CM453232-100JL is preferred for applications with extended storage or high-humidity assembly environments.

Q: Does the operating temperature range difference affect substitution?

A: The IMC1812RW100J operates from -55°C to 125°C, while CM453232-100JL operates from -40°C to 125°C and PM1812-100J-RC from -40°C to 100°C. Substitution is valid only if the application's operating temperature range falls within the substitute part's specification.

Q: Are there core material differences between these parts?

A: Yes. IMC1812RW100J uses iron powder core material, while both Bourns substitutes use ferrite core material. Despite this difference, all three parts deliver identical electrical performance at the specified frequency and current ratings.

Q: What packaging format is used for all three parts?

A: All three inductors are supplied in Tape & Reel (TR) packaging in 1812 (4532 Metric) surface mount format, ensuring compatibility with standard pick-and-place assembly equipment.
