PM105-151K-RC Equivalent & Substitute Parts

Part Overview

The PM105-151K-RC is a 150 µH unshielded drum core wirewound inductor manufactured by Bourns Inc., designed for surface mount applications. This component is rated for 780 mA continuous current with a DC resistance of 470mOhm and operates across the temperature range of -40°C to 125°C. The part is currently active in production status and maintains ROHS3 compliance with unlimited moisture sensitivity rating.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same functional category, allowing for design flexibility in component sourcing and inventory management.

Substitute Part Grouping Explanation

The SDR1006-151KL qualifies as a direct substitute for the PM105-151K-RC based on the following electrical and mechanical equivalence criteria:

Electrical Parameters (Identical):

• Inductance: 150 µH at ±10% tolerance
• Current Rating: 780 mA
• Current - Saturation (Isat): 1.4 A
• DC Resistance: 470 mOhm (specified as maximum in substitute)
• Q @ Frequency: 15 @ 796 kHz
• Frequency - Self Resonant: 4.5 MHz
• Inductance Frequency - Test: 1 kHz
• Operating Temperature Range: -40°C to 125°C

Mechanical Parameters (Identical):

• Mounting Type: Surface Mount
• Size / Dimension: 0.386" L x 0.386" W (9.80 mm x 9.80 mm)
• Height - Seated (Max): 0.228" (5.80 mm)
• Core Type: Drum Core, Wirewound
• Core Material: Ferrite
• Shielding: Unshielded

Compliance & Status (Identical):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected
• Product Status: Active

The primary difference is packaging format: PM105-151K-RC is supplied in Cut Tape (CT), while SDR1006-151KL is supplied in Tape & Reel (TR).

Parameter Comparison

Engineering Selection Recommendations

Both PM105-151K-RC and SDR1006-151KL are active production components from Bourns Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on packaging requirements and inventory availability:

• PM105-151K-RC (Cut Tape): Suitable for lower-volume applications, prototype builds, or situations requiring smaller quantity procurement.
• SDR1006-151KL (Tape & Reel): Appropriate for high-volume manufacturing, automated assembly processes, and production environments utilizing standard reel handling equipment.

Both parts maintain full ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across global markets. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can SDR1006-151KL be used as a direct replacement for PM105-151K-RC in circuit design?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including inductance, current rating, DC resistance, frequency response, and operating temperature range. The only difference is packaging format.

Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging?

A: Cut Tape packaging supplies individual components on tape segments, typically used for manual assembly or low-volume applications. Tape & Reel packaging supplies components on continuous reels, designed for automated pick-and-place assembly systems in high-volume manufacturing.

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

A: No. Both parts carry identical RoHS3 compliance, REACH unaffected status, and MSL rating of 1 (Unlimited). They are functionally equivalent from a regulatory and environmental standpoint.

Q: Does the DC resistance specification difference (470 mOhm vs. 470 mOhm Max) affect substitution?

A: No. The SDR1006-151KL specifies 470 mOhm as a maximum value, which encompasses the nominal 470 mOhm specification of the PM105-151K-RC. This represents equivalent performance within the same tolerance band.

Q: What inventory considerations should guide part selection?

A: PM105-151K-RC has 1,247 pieces in stock, while SDR1006-151KL has 4,614 pieces available. For applications requiring immediate delivery or high-volume procurement, SDR1006-151KL offers greater inventory availability.
