Key Parameters

Substitute Part Grouping Explanation

Substitution for the PM3604-5-B-RC is determined by strict equivalence across the following critical parameters:

• Inductance values in both series (20 µH) and parallel (5 µH) configurations
• Current ratings for both configurations (1.65 A series, 3.3 A parallel)
• DC resistance specifications (76 mOhm max series, 19 mOhm max parallel)
• Tolerance (±20%)
• Number of coils (2)
• Shielding type (unshielded)
• Operating temperature range (-55°C to 125°C)
• Physical dimensions and height
• Mounting type (surface mount)
• Compliance certifications (ROHS3, MSL 1)

The PM3604-5-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 PM3604-5-RC is the appropriate substitute for the obsolete PM3604-5-B-RC. Both parts are manufactured by Bourns Inc. within the PM3600 series and maintain identical electrical specifications and physical dimensions. The substitute part carries active product status, ensuring continued availability and supply chain reliability. Both parts maintain ROHS3 compliance and MSL 1 rating, meeting environmental and moisture sensitivity requirements. The packaging difference (bulk versus tape & reel) does not affect electrical or mechanical compatibility and is determined by procurement and assembly requirements.

Frequently Asked Questions (FAQ)

Q: Can PM3604-5-RC replace PM3604-5-B-RC in existing designs?

A: Yes. The PM3604-5-RC is electrically and mechanically equivalent to the PM3604-5-B-RC. All inductance values, current ratings, DC resistance specifications, operating temperature range, physical dimensions, and compliance certifications are identical.

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

A: The primary difference is packaging format. The PM3604-5-B-RC uses bulk packaging, while the PM3604-5-RC uses tape & reel (TR) packaging. Additionally, the PM3604-5-RC maintains active product status, whereas the PM3604-5-B-RC is obsolete.

Q: Are there any compatibility concerns with the packaging change?

A: No. Tape & reel packaging is standard for surface mount components and is compatible with automated assembly equipment. The component itself remains unchanged.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the PM3604-5-B-RC and PM3604-5-RC are ROHS3 compliant with MSL 1 rating. Compliance certifications are identical.

Q: What inductance values does this component provide?

A: The PM3604-5-RC provides 20 µH when coils are connected in series and 5 µH when connected in parallel, with corresponding current ratings of 1.65 A and 3.3 A respectively.

Q: Is the physical footprint identical between the two parts?

A: Yes. Both parts have identical dimensions of 0.550" L x 0.452" W (13.97 mm x 11.48 mm) with a height of 0.265" (6.73 mm), ensuring direct PCB compatibility.
