P0841 Equivalent & Substitute Parts

Part Overview

The P0841 is a 22.8 µH shielded toroidal inductor rated for 4.9 A with 36mOhm DC resistance, designed for through-hole mounting in radial, vertical orientation. Manufactured by Pulse Electronics under the KlipMount™ series, this component is classified as obsolete. Due to its obsolete status and limited availability relative to active alternatives, identifying equivalent substitute parts is essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P0841 is determined by strict equivalence across the following critical parameters:

• Inductance value: 22.8 µH
• Tolerance: ±20%
• Current rating: 4.9 A minimum
• DC resistance: 36mOhm
• Shielding type: Shielded
• Inductor type: Toroidal
• Mounting configuration: Through hole, radial vertical orientation
• Physical dimensions: 0.830" L x 0.450" W, 0.950" max height
• Operating temperature range: -40°C ~ 130°C

The P0841NL meets all these criteria and is classified as a direct substitute. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The P0841NL is the direct functional equivalent of the P0841. All electrical and mechanical parameters are identical. Selection between these parts should be based on the following factors:

Product Status: The P0841 is obsolete with limited inventory (928 pcs). The P0841NL is active with significantly higher availability (2640 pcs), making it the preferred choice for new designs and ongoing production.

Regulatory Compliance: The P0841NL is ROHS3 compliant, whereas the P0841 is RoHS non-compliant. For applications subject to RoHS regulations, the P0841NL is the required selection.

Packaging: The P0841 is supplied in bulk packaging, while the P0841NL is supplied in tube packaging. Packaging selection depends on assembly process requirements and inventory management practices.

REACH and ECCN Status: Both parts share identical REACH (Unaffected) and ECCN (EAR99) classifications.

Frequently Asked Questions (FAQ)

Q: Can P0841NL be used as a direct replacement for P0841 in existing designs?

A: Yes. The P0841NL is electrically and mechanically identical to the P0841. All critical parameters—inductance, current rating, DC resistance, shielding, dimensions, and operating temperature range—are exact matches. No circuit modifications are required.

Q: What is the difference between P0841 and P0841NL?

A: The parts are functionally equivalent. The primary differences are product status (P0841 is obsolete; P0841NL is active), packaging format (bulk vs. tube), and RoHS compliance (P0841NL is ROHS3 compliant; P0841 is non-compliant).

Q: Why should I choose P0841NL over P0841?

A: The P0841NL is recommended for new designs and production due to active product status, higher inventory availability, and ROHS3 compliance. The P0841 should be reserved for legacy system maintenance only.

Q: Are there any compatibility concerns with PCB layout or mounting?

A: No. Both parts use identical through-hole radial vertical mounting with the same physical dimensions (0.830" L x 0.450" W, 0.950" max height). PCB footprints and assembly processes remain unchanged.

Q: Does packaging format affect electrical performance?

A: No. Tube and bulk packaging formats do not affect component electrical characteristics. Packaging selection is based on assembly process requirements and inventory handling practices.
