Engineering Selection Recommendations

Primary Part Selection (8532-29L): The API Delevan 8532-29L is the original specification component and remains the first choice when available. This part is active in production with 688 units in current stock inventory.

Substitute Part Selection (8532R-29L): The API Delevan 8532R-29L is a direct electrical and mechanical equivalent suitable for applications where RoHS3 compliance is required. This substitute maintains identical performance across all critical parameters: inductance, current rating, saturation current, DC resistance, core material, shielding configuration, temperature range, and physical dimensions. The primary distinction is RoHS compliance status, with the 8532R-29L meeting RoHS3 requirements while the 8532-29L does not. The 8532R-29L is active in production with 831 units in current stock inventory.

Selection Criteria:

• Use 8532-29L when RoHS compliance is not a design requirement and original part availability is confirmed.
• Use 8532R-29L when RoHS3 compliance is mandated by design specifications, customer requirements, or regulatory obligations.
• Both parts are suitable for identical circuit applications due to complete electrical and mechanical equivalence.

Frequently Asked Questions (FAQ)

Q: Are the 8532-29L and 8532R-29L electrically identical?

A: Yes. Both parts have identical inductance (220 µH), current rating (840 mA), saturation current (430 mA), DC resistance (505 mOhm maximum), core material (ferrite), shielding configuration (unshielded), and operating temperature range (-55°C to 125°C). They are electrically interchangeable in circuit applications.

Q: Are the 8532-29L and 8532R-29L mechanically identical?

A: Yes. Both parts have identical mounting type (surface mount), package dimensions (0.860" L × 0.320" W / 21.84mm × 8.12mm), seated height (0.286" / 7.26mm), and moisture sensitivity level (MSL 1). They are mechanically interchangeable on PCBs designed for either part number.

Q: What is the difference between these two parts?

A: The primary difference is RoHS compliance status. The 8532R-29L is RoHS3 compliant, while the 8532-29L is RoHS non-compliant. All electrical and mechanical specifications are identical.

Q: Can I use 8532R-29L in place of 8532-29L?

A: Yes, the 8532R-29L is a direct substitute for the 8532-29L in all circuit applications. No circuit modifications or PCB layout changes are required.

Q: Can I use 8532-29L in place of 8532R-29L?

A: The 8532-29L is electrically and mechanically equivalent to the 8532R-29L. However, if RoHS3 compliance is a design requirement, the 8532-29L does not meet this specification and should not be used.

Q: What packaging format is available for both parts?

A: Both the 8532-29L and 8532R-29L are supplied in Tape & Reel (TR) packaging format.

Q: Are there any temperature or frequency limitations I should consider?

A: Both parts operate across the identical temperature range of -55°C to 125°C. Inductance is specified at 1 kHz test frequency. No additional frequency or temperature limitations apply beyond these specifications.

Q: What is the current saturation point for these inductors?

A: Both parts have a saturation current (Isat) of 430 mA. The rated current is 840 mA, which is above the saturation point. Verify that your application current does not exceed the 840 mA rating.

Q: Are these parts suitable for high-frequency applications?

A: The inductance specification is defined at 1 kHz. Self-resonant frequency data is not provided in the specifications. Consult API Delevan technical documentation for frequency response characteristics if high-frequency operation is required.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply.
