Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PM3602-33-B-RC is determined by strict equivalence across the following critical parameters:

• Inductance values in both parallel (33 µH) and series (132 µH) configurations
• Current ratings for parallel (980 mA) and series (490 mA) operation
• DC resistance specifications (140 mOhm max parallel, 560 mOhm max series)
• Number of coils (2)
• Tolerance (±20%)
• Shielding type (unshielded)
• Operating temperature range (-55°C ~ 125°C)
• Physical dimensions and mounting type (surface mount, nonstandard package)
• Compliance certifications (ROHS3, REACH Unaffected)

The PM3602-33-RC qualifies as a direct substitute based on identical electrical and mechanical specifications. The primary distinction is packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The PM3602-33-RC is the direct equivalent for the obsolete PM3602-33-B-RC. Both components are manufactured by Bourns Inc. within the PM3600 series and maintain identical electrical specifications, mechanical dimensions, and compliance certifications. The PM3602-33-RC is currently in active production status, ensuring supply chain availability and long-term support.

The distinction between the two parts is limited to packaging format: the main part is supplied in bulk packaging, while the substitute is supplied in Tape & Reel (TR) format. This packaging difference does not affect component functionality or performance characteristics. Selection between these parts should be based on procurement requirements and assembly process compatibility with the available packaging format.

Frequently Asked Questions (FAQ)

Q: Are PM3602-33-B-RC and PM3602-33-RC electrically identical?

A: Yes. Both components have identical inductance values (33 µH parallel, 132 µH series), current ratings (980 mA parallel, 490 mA series), DC resistance specifications (140 mOhm max parallel, 560 mOhm max series), and operating temperature ranges (-55°C ~ 125°C).

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

A: The primary difference is packaging format. PM3602-33-B-RC is supplied in bulk packaging, while PM3602-33-RC is supplied in Tape & Reel (TR) format. The PM3602-33-RC is also in active production status, whereas the PM3602-33-B-RC is obsolete.

Q: Can I use PM3602-33-RC as a direct replacement in my design?

A: Yes, provided your assembly process is compatible with Tape & Reel packaging. The component maintains identical electrical and mechanical specifications, including physical dimensions (0.452" L x 0.354" W x 0.225" H), mounting type (surface mount), and compliance certifications (ROHS3 Compliant, REACH Unaffected).

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical compliance status: ROHS3 Compliant, REACH Unaffected, Moisture Sensitivity Level 1 (Unlimited).

Q: What should I consider when selecting between bulk and Tape & Reel packaging?

A: Selection depends on your assembly process and procurement workflow. Tape & Reel packaging is standard for automated pick-and-place assembly systems, while bulk packaging may be suitable for manual assembly or lower-volume applications. Verify your assembly equipment compatibility before finalizing procurement.
