Key Parameters

Substitute Part Grouping Explanation

The Bourns 2303-H-RC qualifies as a direct substitute based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Inductance value: 15µH ±15% tolerance
• Current rating: 18A minimum
• DC resistance: 6mOhm maximum
• Core material: Iron powder
• Shielding configuration: Unshielded
• Mounting type: Through hole
• Package geometry: Radial, horizontal (open)
• Physical dimensions: 1.280" diameter, 0.650" height maximum
• Operating temperature range: -55°C to 105°C minimum

The 2303-H-RC maintains all specified electrical performance characteristics and physical form factor compatibility with the original 2303-H design.

Parameter Comparison

Engineering Selection Recommendations

The 2303-H-RC offers the advantage of active product status, ensuring continued availability and supply chain reliability. Additionally, the 2303-H-RC achieves ROHS3 compliance, meeting modern regulatory requirements for new designs and production environments where RoHS compliance is mandated. Both parts maintain equivalent REACH and ECCN classifications.

Frequently Asked Questions (FAQ)

Q: Can the 2303-H-RC directly replace the 2303-H in existing designs?

A: Yes. The 2303-H-RC is electrically and mechanically identical to the 2303-H. All electrical parameters, physical dimensions, and mounting characteristics are equivalent, enabling direct substitution without circuit modification.

Q: What is the difference between the 2303-H and 2303-H-RC?

A: The primary differences are product status and regulatory compliance. The 2303-H is obsolete, while the 2303-H-RC is active. The 2303-H-RC achieves ROHS3 compliance, whereas the 2303-H is RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are there packaging differences between these parts?

A: The 2303-H is supplied in standard packaging, while the 2303-H-RC is supplied in bulk packaging. Both maintain identical component specifications and through-hole radial, horizontal mounting configuration.

Q: Does the ROHS3 compliance of the 2303-H-RC affect circuit performance?

A: No. ROHS3 compliance reflects material composition standards and does not alter electrical performance, inductance value, current rating, or DC resistance characteristics.

Q: What inventory considerations apply to these parts?

A: The 2303-H has 709 pieces in stock with obsolete status. The 2303-H-RC has 1180 pieces in stock with active status, providing greater long-term availability assurance for production requirements.
