8532-21L Fixed Inductor - Equivalent & Substitute Parts

Part Overview

The 8532-21L is a 47 µH unshielded surface mount inductor manufactured by API Delevan Inc., rated for 1.84 A continuous current with a maximum DC resistance of 104 mOhm. This component is classified as Active product status and is suitable for applications requiring fixed inductance in compact nonstandard packages.

Substitute parts become necessary when the original 8532-21L experiences supply constraints, when design revisions require improved compliance certifications, or when inventory availability impacts production schedules. The substitute identified maintains electrical and mechanical compatibility while offering enhanced regulatory compliance.

Substitute Part Grouping Explanation

The 8532R-21L qualifies as a direct substitute for the 8532-21L based on strict electrical and mechanical parameter equivalence. Substitution is valid when the following criteria are met:

Critical Matching Parameters:

• Inductance value: 47 µH (identical)
• Inductance tolerance: ±15% (identical)
• Current rating: 1.84 A (identical)
• Saturation current: 930 mA (identical)
• DC resistance: 104 mOhm Max (identical)
• Core material: Ferrite (identical)
• Shielding configuration: Unshielded (identical)
• Operating temperature range: -55°C to 125°C (identical)
• Physical dimensions: 0.860" L x 0.320" W, 0.286" height (identical)
• Mounting type: Surface Mount (identical)
• Package classification: Nonstandard (identical)

The substitute part maintains complete electrical performance equivalence and identical mechanical fit within the specified PCB footprint and assembly envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the 8532-21L and 8532R-21L are Active status products from API Delevan Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on regulatory compliance requirements:

The 8532-21L is RoHS non-compliant and suitable for applications without RoHS3 compliance mandates. The 8532R-21L is ROHS3 compliant and is the appropriate selection for designs requiring adherence to RoHS3 regulations. Both parts maintain REACH Unaffected status and EAR99 export classification.

For new designs or production revisions targeting markets with RoHS3 requirements, the 8532R-21L provides equivalent electrical performance with enhanced regulatory compliance. For legacy systems or applications without RoHS3 constraints, either part delivers identical functional performance.

Frequently Asked Questions (FAQ)

Q: Are the 8532-21L and 8532R-21L electrically interchangeable?

A: Yes. Both inductors provide identical inductance (47 µH ±15%), current rating (1.84 A), saturation current (930 mA), and DC resistance (104 mOhm Max). Electrical performance is equivalent across all specified operating conditions.

Q: Do these parts fit the same PCB footprint?

A: Yes. Both parts share identical physical dimensions (0.860" L x 0.320" W, 0.286" maximum seated height) and nonstandard package classification. PCB layout and assembly tooling require no modification.

Q: What is the primary difference between these two part numbers?

A: The 8532R-21L is ROHS3 compliant, while the 8532-21L is RoHS non-compliant. All other electrical, mechanical, and regulatory characteristics are identical.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For designs requiring RoHS3 compliance, specify the 8532R-21L. For applications without RoHS3 mandates, either part is acceptable based on availability and supply chain considerations.

Q: Are there any temperature or frequency limitations that affect substitution?

A: No. Both parts operate across the identical temperature range (-55°C to 125°C) and are tested at 1 kHz. No frequency or temperature-related restrictions apply to substitution.

Q: What is the moisture sensitivity classification for these inductors?

A: Both parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity constraints during storage, handling, or assembly.
