Substitute Part Grouping Explanation

Substitution eligibility for the PM3604-300-B-RC is determined by strict equivalence across the following critical parameters:

• Number of coils: 2
• Inductance values: 300 µH (parallel) and 1.2 mH (series)
• Inductance tolerance: ±20%
• Current ratings: 520 mA (parallel) and 260 mA (series)
• DC resistance specifications: 730 mOhm Max (parallel) and 2.92 Ohm Max (series)
• Operating temperature range: -55°C to 125°C
• Mounting type: Surface Mount
• Physical dimensions: 0.550" L x 0.452" W x 0.265" H
• Shielding configuration: Unshielded
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

The PM3604-300-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 PM3604-300-RC is the qualified substitute for the obsolete PM3604-300-B-RC. Both components are manufactured by Bourns Inc. within the PM3600 series and maintain identical electrical and mechanical specifications. The substitute part carries Active product status, ensuring continued availability and manufacturing support.

Both parts satisfy ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The packaging difference—bulk versus Tape & Reel format—does not affect electrical performance or mechanical compatibility in circuit applications. Selection between these parts should be based on procurement requirements and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can PM3604-300-RC replace PM3604-300-B-RC in existing designs?

A: Yes. The PM3604-300-RC provides identical electrical performance and mechanical fit. The components share the same inductance values, current ratings, DC resistance specifications, operating temperature range, and physical dimensions.

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

A: The primary difference is packaging format. PM3604-300-B-RC is supplied in bulk packaging, while PM3604-300-RC is supplied in Tape & Reel format. Additionally, PM3604-300-RC maintains Active product status, whereas PM3604-300-B-RC is classified as Obsolete.

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 Compliant and REACH Unaffected. Moisture Sensitivity Level is identical at MSL 1 (Unlimited) for both components.

Q: Will the Tape & Reel packaging affect circuit performance?

A: No. Packaging format does not affect electrical or mechanical performance. The component itself remains unchanged; only the delivery and handling format differs.

Q: What are the critical parameters for substitution?

A: Substitution is valid when the following parameters match: number of coils (2), inductance values (300 µH parallel / 1.2 mH series), tolerance (±20%), current ratings (520 mA parallel / 260 mA series), DC resistance (730 mOhm Max parallel / 2.92 Ohm Max series), operating temperature (-55°C to 125°C), mounting type (Surface Mount), and physical dimensions (0.550" L x 0.452" W x 0.265" H).
