Hammond Manufacturing 1534C Equivalent & Substitute Parts

Part Overview

The Hammond Manufacturing 1534C is a 2.4 mH unshielded wirewound axial inductor rated for 160 mA with a maximum DC resistance of 15 ohms. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The 1534C operates at a self-resonant frequency of 1.7 MHz with a quality factor of 80 at 250 kHz, suitable for general-purpose filtering and tuning applications in through-hole configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 1534C is determined by the following critical parameters:

• Inductance Value: 2.4 mH ±5% tolerance (acceptable range: 2.28–2.52 mH)
• Current Rating: Minimum 160 mA to support the original design current
• DC Resistance: Maximum 15 ohms to maintain circuit performance
• Mounting Type: Through hole axial configuration
• Shielding: Unshielded construction
• Compliance: ROHS3 compliance required

The substitute parts listed below meet the inductance and tolerance requirements. However, variations in current rating, DC resistance, and core material introduce trade-offs that must be evaluated based on circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

API Delevan 2500R-46J: This substitute matches the 2.4 mH inductance and ±5% tolerance exactly. However, the current rating of 67 mA is significantly lower than the 1534C's 160 mA specification, and the DC resistance of 31 ohms exceeds the 15 ohm maximum. This part is suitable only for applications where circuit current does not exceed 67 mA and higher DC resistance is acceptable. The part is active and ROHS3 compliant.

EPCOS - TDK B82145A1225J000: This substitute provides a higher current rating of 250 mA and lower DC resistance of 8 ohms, both favorable compared to the 1534C. The inductance is 2.2 mH, which falls within the ±5% tolerance band of the 2.4 mH specification (acceptable range: 2.28–2.52 mH). The lower self-resonant frequency of 800 kHz versus 1.7 MHz may affect high-frequency performance. The part is active, ROHS3 compliant, and rated for -55°C to 125°C operation.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan 2500R-46J directly replace the 1534C?

A: Direct replacement is not recommended. While inductance matches at 2.4 mH, the 67 mA current rating is insufficient for the original 160 mA specification, and the 31 ohm DC resistance exceeds the 15 ohm maximum. Use only if circuit current is confirmed below 67 mA and higher resistance is tolerable.

Q: Is the EPCOS B82145A1225J000 a suitable substitute?

A: The B82145A1225J000 meets or exceeds most electrical parameters: 250 mA current rating, 8 ohm DC resistance, and 2.2 mH inductance (within ±5% tolerance). The lower self-resonant frequency of 800 kHz may impact circuits operating near 1.7 MHz. Verify frequency-dependent performance in your application.

Q: What is the inductance tolerance range for the 1534C?

A: With ±5% tolerance on 2.4 mH, the acceptable range is 2.28 mH to 2.52 mH. The B82145A1225J000 at 2.2 mH falls outside this range and should be evaluated for circuit sensitivity to inductance variation.

Q: Are all substitute parts through-hole axial components?

A: Yes. Both the API Delevan 2500R-46J and EPCOS B82145A1225J000 are through-hole axial inductors, matching the 1534C package configuration.

Q: What compliance certifications apply to these parts?

A: All three parts are ROHS3 compliant. The B82145A1225J000 is REACH Affected; the 1534C and 2500R-46J are REACH Unaffected. All carry EAR99 ECCN classification.
