Substitute Part Grouping Explanation

The 8532R-15L qualifies as a direct substitute for the 8532-15L based on strict electrical and mechanical parameter equivalence. Substitution is valid when the following criteria are met:

• Inductance value matches exactly: 15 µH
• Inductance tolerance is identical: ±15%
• Current rating is equivalent: 2.97 A
• Saturation current matches: 1.6 A
• DC resistance specification is identical: 40 mOhm Max
• Core material is the same: Ferrite
• Shielding configuration matches: Unshielded
• Operating temperature range is identical: -55°C to 125°C
• Physical dimensions are identical: 0.860" L x 0.320" W (21.84 mm x 8.12 mm)
• Height specification matches: 0.286" (7.26 mm) Max
• Mounting type is identical: Surface Mount
• Moisture sensitivity level matches: 1 (Unlimited)

The 8532R-15L is manufactured by the same supplier (API Delevan Inc.) and belongs to the 8532R series, representing an updated variant of the original 8532 series.

Parameter Comparison

Engineering Selection Recommendations

Both the 8532-15L and 8532R-15L maintain Active product status and are available from the manufacturer. The primary distinction between these parts is compliance certification: the 8532R-15L is ROHS3 compliant, while the 8532-15L is RoHS non-compliant. For applications subject to RoHS regulations or requiring compliance with current environmental standards, the 8532R-15L is the appropriate selection. Both parts are REACH Unaffected and classified under ECCN EAR99. The 8532R-15L currently maintains higher inventory availability (1470 Pcs) compared to the 8532-15L (716 Pcs), making it a practical alternative for procurement planning.

Frequently Asked Questions (FAQ)

Q: Can the 8532R-15L be used as a direct replacement for the 8532-15L in existing designs?

A: Yes. All electrical parameters, mechanical dimensions, and thermal specifications are identical between the two parts. The 8532R-15L is electrically and mechanically interchangeable with the 8532-15L.

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

A: The 8532R-15L is ROHS3 compliant, while the 8532-15L is RoHS non-compliant. Both parts are manufactured by API Delevan Inc. and share identical electrical and physical specifications.

Q: Are there any PCB layout or assembly considerations when switching from 8532-15L to 8532R-15L?

A: No. Both parts use identical Surface Mount packaging with the same dimensions (0.860" L x 0.320" W, 21.84 mm x 8.12 mm) and height (0.286" max, 7.26 mm max). No PCB layout modifications are required.

Q: Which part should be selected for new designs?

A: The 8532R-15L is recommended for new designs due to ROHS3 compliance and higher current inventory availability.

Q: Do these parts have any moisture sensitivity concerns?

A: Both parts are rated at Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are the saturation current specifications identical?

A: Yes. Both the 8532-15L and 8532R-15L have a saturation current (Isat) of 1.6 A, which must not be exceeded in circuit operation.
