PM3604-100-B-RC Equivalent & Substitute Parts

Part Overview

The PM3604-100-B-RC is an unshielded 2-coil inductor array manufactured by Bourns Inc. from the PM3600 series. This component provides dual inductance configurations: 100 µH when coils are connected in parallel and 400 µH when connected in series. The part is classified as obsolete, making identification of suitable substitutes necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PM3604-100-B-RC is determined by the following critical parameters:

• Inductance values: Both parallel (100 µH) and series (400 µH) configurations must match exactly
• Current ratings: Parallel configuration 980 mA and series configuration 490 mA must be maintained
• DC resistance: Maximum DCR values of 210 mOhm (parallel) and 840 mOhm (series) establish performance boundaries
• Number of coils: Dual-coil configuration is mandatory
• Shielding type: Unshielded construction must be preserved
• Operating temperature range: -55°C to 125°C compatibility required
• Mounting and package: Surface mount, nonstandard package with specified dimensions (13.97 mm x 11.48 mm x 6.73 mm height)
• Electrical tolerance: ±20% tolerance specification must be maintained

The PM3604-100-RC qualifies as a direct substitute based on identical electrical and mechanical specifications across all parameters listed above.

Parameter Comparison

Engineering Selection Recommendations

The PM3604-100-RC is the qualified substitute for the obsolete PM3604-100-B-RC. Both parts are manufactured by Bourns Inc. within the PM3600 series and share identical electrical specifications and mechanical dimensions.

The primary distinction between these parts is product status and packaging format. The main part (PM3604-100-B-RC) is obsolete and supplied in bulk packaging, while the substitute (PM3604-100-RC) maintains active production status and is available in Tape & Reel (TR) format. Both parts maintain ROHS3 compliance and MSL Level 1 rating.

Selection of the PM3604-100-RC eliminates obsolescence risk and provides access to active inventory channels. The Tape & Reel packaging format is standard for automated assembly processes and offers improved handling and traceability compared to bulk packaging.

Frequently Asked Questions (FAQ)

Q: Can the PM3604-100-RC be used as a direct replacement for the PM3604-100-B-RC?

A: Yes. Both parts are electrically and mechanically identical. The PM3604-100-RC is the active production equivalent with identical inductance values (100 µH parallel, 400 µH series), current ratings (980 mA parallel, 490 mA series), DC resistance specifications, and physical dimensions.

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

A: The PM3604-100-B-RC is classified as obsolete and supplied in bulk packaging. The PM3604-100-RC is the active production variant supplied in Tape & Reel (TR) format. All electrical and mechanical parameters are identical.

Q: Does the packaging format affect electrical performance?

A: No. Tape & Reel (TR) packaging is a handling and delivery format only. It does not alter the component's electrical characteristics, inductance values, current ratings, or DC resistance specifications.

Q: Are both parts RoHS compliant?

A: Yes. Both the PM3604-100-B-RC and PM3604-100-RC are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity rating.

Q: What are the key parameters that must match for substitution?

A: Critical parameters include inductance values in both parallel (100 µH) and series (400 µH) configurations, current ratings (980 mA parallel, 490 mA series), maximum DC resistance (210 mOhm parallel, 840 mOhm series), dual-coil configuration, unshielded construction, operating temperature range (-55°C to 125°C), and physical dimensions (13.97 mm x 11.48 mm x 6.73 mm height).

Q: Is the ±20% tolerance specification maintained in the substitute part?

A: Yes. The PM3604-100-RC maintains the ±20% tolerance specification identical to the main part.
