Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 8532-28L are identified based on strict electrical and mechanical parameter matching. The substitution criteria are:

Electrical Parameters (Must Match):

• Inductance value: 180 µH
• Inductance tolerance: ±15%
• Current rating: 990 mA minimum
• Saturation current (Isat): 480 mA minimum
• DC resistance (DCR): 362 mOhm maximum
• Core material: Ferrite
• Shielding configuration: Unshielded

Mechanical Parameters (Must Match):

• Mounting type: Surface Mount
• Package dimensions: 0.860" L × 0.320" W (21.84mm × 8.12mm)
• Height - Seated (Max): 0.286" (7.26mm)
• Packaging format: Tape & Reel (TR)

Environmental Parameters (Must Match):

• Operating temperature range: -55°C to 125°C
• Moisture Sensitivity Level: 1 (Unlimited)

The 8532R-28L qualifies as a direct substitute because all electrical, mechanical, and environmental specifications are identical to the main part number.

Parameter Comparison

Engineering Selection Recommendations

The 8532R-28L serves as a direct electrical and mechanical substitute for the 8532-28L. Both components are manufactured by API Delevan Inc. and share identical inductance, current rating, DC resistance, core material, shielding configuration, operating temperature range, and physical dimensions.

The primary distinction between these part numbers is regulatory compliance status. The 8532-28L is RoHS non-compliant, while the 8532R-28L is ROHS3 compliant. The 8532R-28L is suitable for applications subject to RoHS3 requirements. Both parts maintain REACH Unaffected status and carry the same EAR99 export classification.

Inventory availability differs between the two part numbers. The 8532-28L has 716 units in stock, while the 8532R-28L has 1423 units available. Selection between these substitutes should be based on regulatory compliance requirements for the end application and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can the 8532R-28L replace the 8532-28L in existing circuit designs?

A: Yes. The 8532R-28L is electrically and mechanically identical to the 8532-28L. All electrical parameters including inductance, current rating, DC resistance, and saturation current are identical. Physical dimensions and mounting characteristics are also identical, allowing direct board-level substitution without design modification.

Q: What is the difference between the 8532-28L and 8532R-28L?

A: The primary difference is RoHS compliance status. The 8532-28L is RoHS non-compliant, while the 8532R-28L is ROHS3 compliant. All electrical and mechanical specifications are identical between the two part numbers.

Q: Are there any thermal or frequency performance differences between these inductors?

A: No. Both the 8532-28L and 8532R-28L operate across the identical temperature range of -55°C to 125°C. Both are tested at 1 kHz for inductance measurement. No differences in thermal or frequency performance characteristics exist between these part numbers.

Q: What packaging format is used for both part numbers?

A: Both the 8532-28L and 8532R-28L are supplied in Tape & Reel (TR) format, suitable for automated assembly processes. Moisture Sensitivity Level is 1 (Unlimited) for both parts, indicating no special moisture handling requirements during storage or assembly.

Q: Which part number should be selected for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS3 compliance, the 8532R-28L is the appropriate choice. For applications without RoHS compliance requirements, either part number is suitable. The 8532R-28L has higher current inventory availability (1423 units versus 716 units).
