L0806C100KPWST Equivalent & Substitute Parts

Part Overview

The L0806C100KPWST is a 10 µH unshielded drum core wirewound inductor manufactured by KEMET in the 0806 (2016 Metric) surface mount package. This component is rated for 155 mA continuous current with a DC resistance of 500 mOhm and operates across the temperature range of -40°C to 105°C. The part is classified as obsolete, making identification of suitable equivalent components necessary for ongoing production and design continuity. Substitute parts must maintain the same inductance value, package footprint, and core material while accommodating variations in current rating and DC resistance within acceptable design parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the L0806C100KPWST is determined by strict equivalence in the following parameters:

Critical Parameters (Must Match):

• Inductance: 10 µH
• Inductance Tolerance: ±10%
• Package / Case: 0806 (2016 Metric)
• Material - Core: Ferrite
• Shielding: Unshielded
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation Parameters:

• Current Rating: Substitute parts must equal or exceed 155 mA
• DC Resistance (DCR): Substitute parts may vary from the original 500 mOhm specification based on design requirements
• Operating Temperature Range: Substitute parts must support minimum -40°C to 105°C or equivalent
• Product Status: Active or Not For New Designs status acceptable for substitution purposes

The two identified substitute parts meet all critical parameters while providing alternative current ratings and DC resistance characteristics suitable for the 0806 package form factor.

Parameter Comparison

Engineering Selection Recommendations

CBC2016T100K (Taiyo Yuden): This substitute provides the highest current rating at 350 mA, exceeding the original 155 mA specification. The increased DC resistance of 1.066 Ohm Max compared to the original 500 mOhm must be evaluated for thermal and power dissipation impact in the target application. The part maintains identical operating temperature range (-40°C to 105°C) and self-resonant frequency (32 MHz) as the original. Product status is Not For New Designs, indicating limited long-term availability. ROHS3 compliance and MSL 1 rating match the original specification.

LQH2MCN100K02L (Murata Electronics): This substitute is classified as Active, providing the best long-term availability and supply chain continuity. Current rating of 225 mA exceeds the original 155 mA requirement. DC resistance of 1.56 Ohm Max represents a significant increase from the original 500 mOhm and requires thermal analysis for the specific application. Operating temperature range is limited to -40°C to 85°C, which is 20°C lower than the original maximum. Self-resonant frequency is higher at 48 MHz. ROHS3 compliance and MSL 1 rating are maintained. Physical height is reduced to 0.037" (0.95mm) compared to the original 0.071" (1.80mm), which may affect PCB layout considerations.

For applications requiring the full -40°C to 105°C temperature range, CBC2016T100K is the appropriate selection. For applications operating within -40°C to 85°C, LQH2MCN100K02L offers superior long-term availability as an Active product.

Frequently Asked Questions (FAQ)

Q: Can the L0806C100KPWST be directly replaced with CBC2016T100K or LQH2MCN100K02L?

A: Direct replacement is possible when the substitute part meets the application requirements. Both substitutes maintain the 10 µH inductance, ±10% tolerance, 0806 (2016 Metric) package, ferrite core material, unshielded configuration, and surface mount mounting type. However, the increased DC resistance in both substitutes (1.066 Ohm and 1.56 Ohm respectively, compared to 500 mOhm) must be evaluated for power dissipation and thermal performance in the specific circuit.

Q: What is the impact of higher DC resistance in the substitute parts?

A: DC resistance directly affects power dissipation according to P = I²R. At the original 155 mA current level, the L0806C100KPWST dissipates approximately 12 mW, while CBC2016T100K dissipates approximately 26 mW and LQH2MCN100K02L dissipates approximately 37 mW. Applications sensitive to thermal performance or operating in high-temperature environments must account for this increased dissipation.

Q: Are there temperature range limitations with the substitute parts?

A: The CBC2016T100K maintains the original operating range of -40°C to 105°C. The LQH2MCN100K02L is limited to -40°C to 85°C, which is 20°C lower than the original maximum. Applications requiring operation above 85°C must use CBC2016T100K or the original part.

Q: How do the current ratings compare?

A: The original L0806C100KPWST is rated for 155 mA continuous current. CBC2016T100K provides 350 mA rating with 380 mA saturation current. LQH2MCN100K02L provides 225 mA rating. Both substitutes exceed the original current requirement, providing design margin for applications with variable or peak current demands.

Q: What are the physical dimension differences?

A: All three parts share the same 0806 (2016 Metric) package footprint with dimensions of 0.079" L x 0.063" W (2.00mm x 1.60mm). The seated height differs: L0806C100KPWST and CBC2016T100K are 0.071" (1.80mm), while LQH2MCN100K02L is 0.037" (0.95mm). The reduced height of the Murata part may affect PCB clearance and component placement considerations.

Q: What is the product status significance?

A: L0806C100KPWST is classified as Obsolete, indicating discontinued production. CBC2016T100K is Not For New Designs, indicating limited future availability. LQH2MCN100K02L is Active, indicating current production and long-term supply chain support. For new designs, LQH2MCN100K02L is the preferred selection when temperature range requirements permit.

Q: Are all parts RoHS3 compliant?

A: Yes, all three parts are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions and full compliance with environmental regulations.
