Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PM3604-150-B-RC is determined by strict equivalence across the following critical parameters:

• Number of coils: 2
• Inductance values: 150 µH (parallel) and 600 µH (series)
• Tolerance: ±20%
• Current ratings: 780 mA (parallel) and 390 mA (series)
• DC resistance specifications: 320 mOhm Max (parallel) and 1.28 Ohm Max (series)
• Shielding configuration: Unshielded
• Operating temperature range: -55°C to 125°C
• Mounting type: Surface Mount
• Physical dimensions and height
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

The PM3604-150-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 PM3604-150-RC is the direct equivalent for the obsolete PM3604-150-B-RC. Both parts maintain identical electrical specifications, mechanical dimensions, and regulatory compliance certifications. The substitute part carries Active product status, ensuring continued availability and manufacturing support.

The distinction between the two parts is limited to packaging format: the main part is supplied in bulk configuration, while the substitute is supplied in Tape & Reel format. This packaging difference does not affect component performance, electrical characteristics, or PCB assembly compatibility.

Selection of the PM3604-150-RC is appropriate for applications requiring the specified inductance values, current ratings, and operating temperature range. Both ROHS3 compliance and REACH unaffected status are maintained.

Frequently Asked Questions (FAQ)

Q: Can PM3604-150-RC replace PM3604-150-B-RC in existing designs?

A: Yes. The parts are electrically and mechanically identical. The only difference is packaging format (Tape & Reel versus bulk). PCB footprint, component performance, and electrical characteristics are equivalent.

Q: What is the significance of the product status change from Obsolete to Active?

A: The PM3604-150-RC maintains Active status, indicating ongoing manufacturing and availability. This ensures reliable procurement for new production runs and design revisions.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts maintain identical ROHS3 compliance and REACH unaffected status. Regulatory requirements are fully satisfied by either part.

Q: Does packaging format affect assembly or performance?

A: Packaging format (bulk versus Tape & Reel) affects procurement and handling procedures but does not impact electrical performance, thermal characteristics, or PCB assembly compatibility. Component specifications remain identical.

Q: What are the critical parameters for substitution eligibility?

A: Substitution is based on matching inductance values (150 µH parallel, 600 µH series), current ratings (780 mA parallel, 390 mA series), DC resistance specifications, tolerance (±20%), number of coils (2), shielding configuration (unshielded), operating temperature range (-55°C to 125°C), and physical dimensions (0.550" L × 0.452" W × 0.265" H).
