Substitute Part Grouping Explanation

Substitution eligibility for the PE-53662 is determined by strict equivalence across the following critical parameters:

• Inductance Value: 4.9 µH (exact match required)
• Current Rating: 7.8 A (exact match required)
• DC Resistance: 12.4 mOhm Max (exact match required)
• Inductor Type: Toroidal (exact match required)
• Shielding Configuration: Unshielded (exact match required)
• Mounting Technology: Surface Mount (exact match required)
• Physical Dimensions: 15.75mm × 15.24mm × 9.91mm seated height (exact match required)
• Operating Temperature Range: -40°C ~ 130°C (exact match required)

The PE-53662NL qualifies as a direct substitute based on complete alignment with all electrical and mechanical parameters. The primary distinction is product status and compliance certification.

Engineering Selection Recommendations

The PE-53662NL is the direct equivalent substitute for the obsolete PE-53662. Selection of PE-53662NL is justified on the following basis:

• Electrical Equivalence: Identical inductance (4.9 µH), current rating (7.8 A), and DC resistance (12.4 mOhm Max) ensure functional interchangeability in circuit applications.
• Mechanical Compatibility: Matching physical dimensions and surface mount configuration enable direct PCB layout compatibility without redesign.
• Product Status: PE-53662NL maintains active production status, ensuring long-term availability and supply chain continuity.
• Compliance Enhancement: PE-53662NL achieves ROHS3 compliance, addressing regulatory requirements that the obsolete PE-53662 does not meet.
• Packaging Availability: PE-53662NL is supplied in tube packaging, facilitating standard component handling and inventory management.

Frequently Asked Questions (FAQ)

Q: Can PE-53662NL be used as a direct replacement for PE-53662 in existing designs?

A: Yes. PE-53662NL is electrically and mechanically equivalent to PE-53662. All critical parameters—inductance, current rating, DC resistance, dimensions, and operating temperature range—are identical, enabling direct substitution without circuit modification.

Q: What is the primary advantage of switching to PE-53662NL?

A: PE-53662NL is an active product with ROHS3 compliance certification, whereas PE-53662 is obsolete and RoHS non-compliant. This transition ensures regulatory compliance and supply chain sustainability.

Q: Are there any packaging differences between PE-53662 and PE-53662NL?

A: PE-53662NL is supplied in tube packaging, while PE-53662 packaging is not specified. Tube packaging is standard for component distribution and does not affect electrical or mechanical performance.

Q: Do the parts have identical moisture sensitivity ratings?

A: Yes. Both PE-53662 and PE-53662NL carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture-related handling restrictions.

Q: Is PCB layout modification required when substituting PE-53662NL for PE-53662?

A: No. Identical physical dimensions (15.75mm × 15.24mm × 9.91mm seated height) and surface mount configuration ensure direct footprint compatibility without layout changes.
