Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5504-RC is determined by the following critical parameters:

• Inductance Value: 50 µH (exact match required)
• Current Rating: 5.6 A minimum (equal or higher acceptable)
• DC Resistance: 45 mOhm maximum (lower values acceptable)
• Mounting Type: Through Hole radial configuration
• Physical Dimensions: 0.810" Dia x 0.880" L (20.57mm x 22.35mm)
• Shielding: Unshielded
• Test Frequency: 1 kHz

The 1538M04 from Hammond Manufacturing meets all substitution criteria. It provides identical inductance, current rating, and physical form factor while offering improved DC resistance performance (40 mOhm Max versus 45 mOhm Max).

Parameter Comparison

Engineering Selection Recommendations

The 1538M04 is the direct substitute for the obsolete 5504-RC. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment in current manufacturing environments.

The 1538M04 offers performance advantages: reduced DC resistance (40 mOhm versus 45 mOhm) and tighter inductance tolerance (±10% versus ±20%). These improvements result in lower power dissipation and more predictable circuit behavior without requiring design modifications.

The 1538M04 is classified as active product status, ensuring ongoing availability and supply chain stability compared to the obsolete 5504-RC.

Frequently Asked Questions (FAQ)

Q: Can the 1538M04 be used as a direct replacement for the 5504-RC in existing designs?

A: Yes. The 1538M04 provides identical inductance (50 µH), current rating (5.6 A), and physical dimensions (0.810" Dia x 0.880" L). Through-hole radial mounting is identical. No PCB layout modifications are required.

Q: What are the differences between these two inductors?

A: The primary differences are DC resistance (1538M04: 40 mOhm Max versus 5504-RC: 45 mOhm Max) and inductance tolerance (1538M04: ±10% versus 5504-RC: ±20%). The 1538M04 provides superior performance characteristics.

Q: Are there any compliance or certification differences?

A: Both components are ROHS3 compliant and REACH unaffected. No compliance barriers exist for substitution.

Q: Why is the 5504-RC obsolete?

A: The 5504-RC is classified as obsolete by Bourns Inc. The 1538M04 from Hammond Manufacturing is the active equivalent, ensuring continued availability and supply chain support.

Q: Will the lower DC resistance of the 1538M04 affect circuit operation?

A: Lower DC resistance reduces power dissipation and heat generation. This is a beneficial characteristic that improves overall circuit efficiency without requiring design changes.
