Key Parameters

Substitute Part Grouping Explanation

Substitution for the 1130-1R2M is determined by strict equivalence across the following critical parameters:

• Inductance Value: 1.2 µH with ±20% tolerance
• Current Rating: 21 A minimum continuous current capacity
• DC Resistance: 3 mOhm maximum
• Core Type: Ferrite drum core, unshielded
• Mounting Configuration: Through-hole radial, vertical cylinder orientation
• Physical Envelope: 1.100" diameter, 0.840" maximum seated height
• Operating Temperature: -55°C to 105°C range
• Inductance Test Frequency: 1 kHz

The 1130-1R2M-RC meets all these criteria and is classified as a direct manufacturer equivalent within the Bourns 1130 series.

Parameter Comparison

Engineering Selection Recommendations

The 1130-1R2M-RC is the direct equivalent substitute for the obsolete 1130-1R2M. Both components are manufactured by Bourns Inc. within the same 1130 series and share identical electrical and mechanical specifications. The primary distinction is product status and regulatory compliance: the 1130-1R2M-RC is currently active in production and meets RoHS3 compliance requirements, whereas the original 1130-1R2M is obsolete and RoHS non-compliant.

For applications requiring RoHS3 compliance or where component availability is critical, the 1130-1R2M-RC is the appropriate selection. Both parts are functionally interchangeable in through-hole PCB applications requiring 1.2 µH inductance at 21 A current rating.

Frequently Asked Questions (FAQ)

Q: Can the 1130-1R2M-RC be used as a direct replacement for the 1130-1R2M?

A: Yes. Both components are electrically and mechanically identical. The 1130-1R2M-RC is the active production equivalent with improved regulatory compliance.

Q: What is the difference between the two part numbers?

A: The 1130-1R2M-RC includes the "-RC" suffix indicating Bourns' current production variant. The original 1130-1R2M is obsolete. Electrical specifications, physical dimensions, and performance characteristics are identical.

Q: Are there packaging differences between these parts?

A: The 1130-1R2M-RC is supplied in bulk packaging, while the original 1130-1R2M packaging specification is not detailed. Both use the same radial, vertical cylinder through-hole package type.

Q: Does the RoHS3 compliance of the 1130-1R2M-RC affect circuit performance?

A: No. RoHS3 compliance relates to material composition and environmental standards, not electrical performance. Both parts deliver identical inductance, current rating, and DC resistance specifications.

Q: What are the critical parameters for substitution?

A: Inductance (1.2 µH ±20%), current rating (21 A), DC resistance (3 mOhm max), core material (ferrite), mounting type (through-hole), and physical dimensions (1.100" diameter, 0.840" height) must remain constant for functional equivalence.
