P1967L Equivalent & Substitute Parts

Part Overview

The P1967L is a 1.44 µH toroidal inductor manufactured by Pulse Electronics, rated for 23.8 A continuous current with a maximum DC resistance of 3.8 mOhm. This component is designed for through-hole mounting in radial, vertical orientation. The part is currently obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution analysis for the P1967L is constrained by the significant differences between the main part and the listed substitute. The PE-51513NL differs substantially in inductance value (144 µH versus 1.44 µH), current rating (10 A versus 23.8 A), and DC resistance (32 mOhm versus 3.8 mOhm). These parameters are fundamental to inductor function and cannot be considered interchangeable without circuit redesign.

The PE-51513NL cannot serve as a direct substitute for the P1967L in applications requiring the specified 1.44 µH inductance and 23.8 A current capacity. Substitution would only be valid in circuits where the higher inductance value, lower current rating, and increased DC resistance are acceptable design modifications.

Engineering Selection Recommendations

The P1967L is obsolete and no longer in active production. The PE-51513NL is the only listed substitute and maintains active product status with ROHS3 compliance, providing regulatory advantage for new designs. However, the PE-51513NL exhibits fundamentally different electrical characteristics that preclude direct substitution in circuits designed for the P1967L specifications.

Selection of PE-51513NL requires circuit-level analysis to confirm compatibility with the modified inductance, current, and resistance parameters. Applications with strict inductance and current requirements should pursue alternative sources for components matching the original P1967L specifications rather than force-fitting the PE-51513NL.

Frequently Asked Questions (FAQ)

Q: Can PE-51513NL replace P1967L in my circuit? A: Direct replacement is not recommended. The PE-51513NL has 100 times higher inductance (144 µH vs 1.44 µH), 58% lower current rating (10 A vs 23.8 A), and 8.4 times higher DC resistance (32 mOhm vs 3.8 mOhm). These differences will alter circuit behavior significantly.

Q: What are the key differences between these parts? A: The primary differences are inductance value, current rating, and DC resistance. Both are toroidal inductors with through-hole mounting and identical operating temperature ranges, but the electrical performance parameters are incompatible for direct substitution.

Q: Why is the P1967L obsolete? A: Product status information indicates obsolescence. Pulse Electronics has transitioned this component out of active production.

Q: Does PE-51513NL offer better compliance? A: Yes. PE-51513NL is ROHS3 compliant, whereas P1967L is RoHS non-compliant. This provides regulatory advantage for new designs, but compliance improvement does not address the electrical parameter mismatches.

Q: What should I do if I need P1967L specifications? A: Evaluate alternative inductor sources from other manufacturers offering 1.44 µH inductance with 23.8 A current rating and similar DC resistance specifications in through-hole toroidal packages.
