PM3602-15-B-RC Equivalent & Substitute Parts

Part Overview

The PM3602-15-B-RC is an unshielded 2-coil inductor array manufactured by Bourns Inc., part of the PM3600 series. This component provides dual inductance configurations: 15 µH when coils are connected in parallel and 60 µH when connected in series. The part is classified as obsolete, making identification of suitable substitutes essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PM3602-15-B-RC is determined by strict equivalence across the following critical parameters:

• Inductance values: Both parallel (15 µH) and series (60 µH) configurations must match exactly
• Inductance tolerance: ±20% specification must be maintained
• Current ratings: Parallel (1.45 A) and series (730 mA) ratings must be met or exceeded
• DC resistance: Maximum DCR values for both configurations must not be exceeded
• Coil configuration: Exactly 2 coils with identical connection topology
• Shielding type: Unshielded construction
• Operating temperature range: -55°C to 125°C minimum
• Physical footprint: Nonstandard package dimensions (11.48mm × 8.99mm × 5.72mm)
• Compliance standards: ROHS3 compliance and MSL 1 rating required

The PM3602-15-RC meets all these criteria and qualifies as a direct substitute. The primary distinction is packaging format: the main part uses bulk packaging while the substitute is supplied in Tape & Reel (TR) format.

Parameter Comparison

Engineering Selection Recommendations

The PM3602-15-RC is the qualified substitute for the obsolete PM3602-15-B-RC. Both parts are manufactured by Bourns Inc. within the PM3600 series and maintain identical electrical and mechanical specifications across all critical parameters.

The primary advantage of selecting PM3602-15-RC is its active product status, ensuring long-term availability and supply chain reliability. Both parts carry ROHS3 compliance certification and MSL 1 rating, meeting current regulatory and environmental standards.

The packaging difference—bulk format for the main part versus Tape & Reel format for the substitute—does not affect component functionality or performance. Tape & Reel packaging is standard for automated assembly processes and provides equivalent component quality and reliability.

Frequently Asked Questions (FAQ)

Q: Can PM3602-15-RC be used as a direct replacement for PM3602-15-B-RC?

A: Yes. Both parts are electrically and mechanically identical. The PM3602-15-RC is the active production equivalent and qualifies as a direct substitute.

Q: What is the difference between bulk and Tape & Reel packaging?

A: Bulk packaging is used for manual handling and small-quantity applications. Tape & Reel (TR) packaging is designed for automated pick-and-place assembly equipment. The components themselves are identical; only the delivery format differs.

Q: Are the inductance values guaranteed to be exactly 15 µH and 60 µH?

A: Inductance values are specified with ±20% tolerance. Parallel configuration inductance ranges from 12 µH to 18 µH; series configuration ranges from 48 µH to 72 µH.

Q: Can this inductor array be used in both series and parallel configurations simultaneously?

A: The component provides two distinct inductance values depending on coil connection configuration. Circuit design determines which configuration is used for a given application.

Q: Does the nonstandard package size affect PCB layout compatibility?

A: The physical footprint (11.48mm × 8.99mm × 5.72mm) is fixed for both the main part and substitute. PCB layouts designed for PM3602-15-B-RC are directly compatible with PM3602-15-RC.

Q: What compliance certifications apply to this component?

A: Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating. REACH status is unaffected for both variants.
