Substitute Part Grouping Explanation

Substitution eligibility for the Bourns 5250 is determined by strict equivalence across the following electrical and mechanical parameters:

• Inductance Value: 100 µH (exact match required)
• Inductance Tolerance: ±20% (exact match required)
• Current Rating: 2 A minimum (exact match required)
• DC Resistance: 216 mOhm maximum (exact match required)
• Core Material: Ferrite drum core (exact match required)
• Shielding Configuration: Unshielded (exact match required)
• Mounting Type: Through hole (exact match required)
• Package Style: Axial (exact match required)
• Physical Dimensions: 0.380" Dia × 1.250" L (exact match required)
• Operating Temperature Range: -55°C to 105°C minimum (exact match required)

The Bourns 5250-RC meets all substitution criteria as a direct equivalent within the 5200 series family.

Parameter Comparison

Engineering Selection Recommendations

The Bourns 5250-RC is the direct functional equivalent of the obsolete Bourns 5250. Both components share identical electrical specifications and physical dimensions, ensuring pin-for-pin and form-factor compatibility in existing circuit designs.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The 5250 is obsolete and carries RoHS non-compliant certification, while the 5250-RC maintains active product status with ROHS3 compliance. For new designs or ongoing production requiring regulatory adherence to RoHS3 standards, the 5250-RC is the appropriate selection. For legacy system maintenance where RoHS compliance is not a requirement, either part satisfies the electrical and mechanical specifications.

Both components are supplied by Bourns Inc. within the 5200 series family, confirming manufacturer continuity and design lineage.

Frequently Asked Questions (FAQ)

Q: Can the Bourns 5250-RC be used as a direct replacement for the Bourns 5250?

A: Yes. The 5250-RC is electrically and mechanically identical to the 5250. Both components feature 100µH inductance, 2A current rating, 216mOhm maximum DC resistance, ferrite drum core construction, unshielded configuration, and identical axial through-hole package dimensions. Direct substitution is supported without circuit modification.

Q: What is the difference between the Bourns 5250 and 5250-RC?

A: The primary differences are product status and regulatory compliance. The 5250 is obsolete and RoHS non-compliant, while the 5250-RC is an active product with ROHS3 compliance. Electrical and mechanical specifications are identical.

Q: Are there packaging differences between these parts?

A: Both components use axial through-hole packaging with identical physical dimensions (0.380" Dia × 1.250" L). The 5250-RC is supplied in bulk packaging, while the 5250 uses standard packaging. This distinction does not affect component functionality or board-level compatibility.

Q: Which part should be selected for new designs?

A: The Bourns 5250-RC should be selected for new designs. It maintains active product status, ensures long-term supply availability, and provides ROHS3 regulatory compliance for modern manufacturing and end-market requirements.

Q: Is the operating temperature range identical between both parts?

A: Yes. Both the 5250 and 5250-RC operate across the identical temperature range of -55°C to 105°C, ensuring thermal performance equivalence in all operating environments.
