PE-53804 Equivalent & Substitute Parts

Part Overview

The PE-53804 is a 79 µH shielded toroidal inductor rated for 250 mA with 1.5Ω DC resistance, designed for through-hole mounting in radial, vertical corner terminal configuration. This part is classified as obsolete, making identification of active equivalent components essential for ongoing production and design continuity. Substitute parts must maintain electrical performance specifications while offering current product availability and compliance status.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PE-53804 are identified based on strict electrical and mechanical parameter matching:

Primary Substitution Criteria:

• Inductance value: 79 µH (±20% tolerance maintained)
• Current rating: 250 mA minimum
• DC resistance: 1.5Ω
• Mounting type: Through hole
• Package configuration: Radial corner terminals
• Operating temperature range: Minimum -40°C to 125°C

Substitution Categories:

Category 1: Direct Manufacturer Equivalent (Active Status) PE-53804NL from Pulse Electronics maintains identical electrical specifications and physical dimensions as the original part. The primary distinction is product status (active vs. obsolete) and RoHS compliance improvement (ROHS3 compliant vs. non-compliant).

Category 2: Cross-Manufacturer Substitute (Different Shielding) SH150T-0.25-79 from Amgis, LLC provides equivalent electrical performance with matching inductance, current rating, and DC resistance. This part differs in shielding configuration (unshielded vs. shielded), core material (iron powder), mounting orientation (horizontal vs. vertical), and physical dimensions. This substitute is applicable only when EMI shielding is not a circuit requirement.

Engineering Selection Recommendations

PE-53804NL (Recommended Primary Substitute)

PE-53804NL is the direct equivalent from the original manufacturer with active product status. This part provides identical electrical and mechanical specifications with improved compliance posture (ROHS3 compliant). Selection of PE-53804NL eliminates obsolescence risk while maintaining full design compatibility without PCB or assembly modifications.

SH150T-0.25-79 (Conditional Substitute)

SH150T-0.25-79 is applicable only when circuit design does not require electromagnetic shielding. This part maintains all critical electrical parameters (inductance, current rating, DC resistance) and offers active product status with ROHS3 compliance. Physical differences include reduced height (0.201" vs. 0.310"), smaller footprint (0.339" vs. 0.360"), horizontal mounting orientation, and unshielded construction. PCB layout modification is required for this substitution.

Frequently Asked Questions (FAQ)

Q: Can PE-53804NL be used as a direct drop-in replacement for PE-53804?

A: Yes. PE-53804NL maintains identical electrical specifications (79 µH, 250 mA, 1.5Ω DCR), physical dimensions (0.360" x 0.360" x 0.310"), and mounting configuration (radial, vertical corner terminals). No circuit or PCB modifications are required.

Q: What is the primary difference between PE-53804 and PE-53804NL?

A: The main differences are product status (obsolete vs. active) and RoHS compliance (non-compliant vs. ROHS3 compliant). Electrical and mechanical performance are identical.

Q: Can SH150T-0.25-79 replace PE-53804 in all applications?

A: SH150T-0.25-79 is suitable only for applications where EMI shielding is not required. The unshielded construction may introduce electromagnetic interference in sensitive circuits. Additionally, the horizontal mounting orientation and reduced physical dimensions require PCB layout changes.

Q: What are the key electrical parameters that must match for substitution?

A: Inductance (79 µH), inductance tolerance (±20%), current rating (250 mA minimum), and DC resistance (1.5Ω) are the critical parameters determining substitution compatibility.

Q: Are there packaging differences between these parts?

A: PE-53804 and PE-53804NL use identical packaging (radial, vertical corner terminals, 0.360" x 0.360" x 0.310"). SH150T-0.25-79 uses radial, horizontal corner terminals with reduced dimensions (0.339" x 0.339" x 0.201"), requiring PCB modification.

Q: Do all substitute parts meet current compliance requirements?

A: PE-53804NL and SH150T-0.25-79 are both ROHS3 compliant and REACH unaffected. The original PE-53804 is RoHS non-compliant. For new designs or compliance-mandated applications, PE-53804NL or SH150T-0.25-79 are required.
