PM54-101K Equivalent & Substitute Parts

Part Overview

The PM54-101K is a 100 µH unshielded drum core wirewound inductor manufactured by Bourns Inc., rated for 520 mA with 700mOhm DC resistance. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The part operates across -30°C to 100°C and is mounted as a surface mount nonstandard package component. Substitute parts maintain the core electrical specifications while offering improved product status and compliance certifications.

Substitute Part Grouping Explanation

Substitute parts for the PM54-101K are classified into two categories based on manufacturer and product status:

Direct Manufacturer Substitutes (Bourns Inc.):

• PM54-101K-RC: Active product status with identical electrical specifications and improved RoHS3 compliance
• SDR0604-101KL: Active product from Bourns SDR0604 series with matching electrical parameters and extended temperature range

Cross-Manufacturer Alternatives:

• CR54NP-101KC (Sumida America Components Inc.): Active product with equivalent electrical specifications
• PD54R-104K (API Delevan Inc.): Active product with equivalent electrical specifications and extended operating temperature

Substitution eligibility is determined by matching the following parameters: inductance value (100 µH), tolerance (±10%), current rating (520 mA), DC resistance (700mOhm), core material (ferrite), shielding type (unshielded), and mounting configuration (surface mount nonstandard package). All substitute parts maintain these core specifications within the defined tolerances.

Parameter Comparison

Engineering Selection Recommendations

For RoHS3 Compliance Requirements: PM54-101K-RC, SDR0604-101KL, CR54NP-101KC, and PD54R-104K all meet ROHS3 compliance standards, whereas the original PM54-101K does not. Selection among these four parts depends on secondary considerations including operating temperature range and manufacturer preference.

For Extended Temperature Range Applications: PD54R-104K provides the widest operating temperature range (-55°C ~ 125°C), suitable for applications requiring extreme temperature performance. SDR0604-101KL and PM54-101K-RC both extend the upper temperature limit to 125°C compared to the original part's 100°C maximum.

For Direct Manufacturer Continuity: PM54-101K-RC and SDR0604-101KL maintain Bourns Inc. as the manufacturer. PM54-101K-RC is the direct packaging variant (Tape & Reel) of the original PM54 series, while SDR0604-101KL represents an alternative Bourns series with identical electrical performance.

For Cross-Manufacturer Alternatives: CR54NP-101KC (Sumida) and PD54R-104K (API Delevan) provide equivalent electrical specifications with active product status and RoHS3 compliance. These options are suitable when manufacturer diversification or supply chain flexibility is required.

Frequently Asked Questions (FAQ)

Q: Can PM54-101K-RC be used as a direct replacement for PM54-101K? A: Yes. PM54-101K-RC maintains identical electrical specifications (100 µH, 520 mA, 700mOhm DCR) and physical dimensions. The primary difference is product status (active vs. obsolete) and packaging format (Tape & Reel). RoHS3 compliance is improved in the RC variant.

Q: What is the difference between PM54-101K-RC and SDR0604-101KL? A: Both are Bourns Inc. products with identical electrical specifications and RoHS3 compliance. PM54-101K-RC belongs to the PM54 series, while SDR0604-101KL belongs to the SDR0604 series. Physical dimensions are identical (5.80mm x 5.80mm x 4.80mm max height). Selection between these parts depends on series preference and supply availability.

Q: Are cross-manufacturer parts (Sumida CR54NP-101KC and API Delevan PD54R-104K) electrically equivalent? A: Yes. Both parts match the core electrical specifications: 100 µH inductance, ±10% tolerance, 520 mA current rating, and 700mOhm maximum DC resistance. Both are RoHS3 compliant and surface mount. Physical dimensions vary slightly but remain within nonstandard package classification.

Q: Which substitute part has the best temperature performance? A: PD54R-104K offers the widest operating temperature range (-55°C ~ 125°C). PM54-101K-RC and SDR0604-101KL both support -40°C ~ 125°C. CR54NP-101KC supports -40°C ~ 100°C, matching the original part's upper limit.

Q: Are all substitute parts available in Tape & Reel packaging? A: Yes. PM54-101K-RC, SDR0604-101KL, CR54NP-101KC, and PD54R-104K are all specified with Tape & Reel (TR) packaging, suitable for automated assembly processes.

Q: What compliance certifications apply to all substitute parts? A: All substitute parts are ROHS3 compliant, RoHS non-compliant status applies only to the original PM54-101K. All parts have Moisture Sensitivity Level 1 (Unlimited). REACH status is unaffected for all parts where specified.
