Substitute Part Grouping Explanation

Substitution of the PE-53611 is determined by strict equivalence across the following critical electrical and mechanical parameters:

• Inductance Value: 383 µH (exact match required)
• Current Rating: 720 mA (exact match required)
• DC Resistance: 862 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: 0.570" L x 0.565" W x 0.360" H max (exact match required)
• Operating Temperature Range: -40°C ~ 130°C (exact match required)

The PE-53611NL is a direct functional equivalent that maintains all specified electrical characteristics and physical form factor while offering improved product status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The PE-53611NL is the direct substitute for the obsolete PE-53611. Both components are manufactured by Pulse Electronics within the SLIC series and maintain identical electrical specifications and physical dimensions. The PE-53611NL offers two significant advantages: active product status ensuring long-term availability and supply chain support, and ROHS3 compliance meeting current regulatory requirements for electronic component manufacturing and distribution. The PE-53611 is classified as RoHS non-compliant, which may restrict its use in applications subject to RoHS directives. Selection of PE-53611NL is appropriate for new designs, production continuity, and compliance-driven applications.

Frequently Asked Questions (FAQ)

Q: Can PE-53611NL be used as a direct replacement for PE-53611 in existing designs?

A: Yes. The PE-53611NL maintains identical inductance (383 µH), current rating (720 mA), DC resistance (862 mOhm Max), inductor type (toroidal), shielding configuration (unshielded), mounting technology (surface mount), physical dimensions (0.570" L x 0.565" W x 0.360" H max), and operating temperature range (-40°C ~ 130°C). No circuit modifications or PCB layout changes are required.

Q: What is the primary reason to transition from PE-53611 to PE-53611NL?

A: The PE-53611 is obsolete, while PE-53611NL maintains active product status. Additionally, PE-53611NL is ROHS3 compliant, whereas PE-53611 is RoHS non-compliant. These factors ensure long-term component availability, regulatory compliance, and supply chain continuity.

Q: Are there any packaging differences between PE-53611 and PE-53611NL?

A: Both components use nonstandard packaging. PE-53611 is supplied in standard packaging, while PE-53611NL is supplied in bulk packaging. The physical component dimensions and form factor remain identical.

Q: Do both parts have the same moisture sensitivity level?

A: Yes. Both PE-53611 and PE-53611NL are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are there any differences in export classification or tariff codes?

A: No. Both components share identical ECCN (EAR99) and HTSUS (8504.50.4000) classifications.
