PM0805-6N8M Equivalent & Substitute Parts

Part Overview

The PM0805-6N8M is a 6.8 nH unshielded drum core wirewound inductor manufactured by Bourns Inc., designed for surface mount applications in the 0805 (2012 Metric) package. This component is rated for 600 mA continuous current with a maximum DC resistance of 110 mOhm and operates across the temperature range of -55°C to 125°C. The part is currently classified as obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PM0805-6N8M is determined by the following critical parameters:

• Inductance Value: 6.8 nH (fixed requirement)
• Package / Case: 0805 (2012 Metric) (fixed requirement)
• Current Rating: 600 mA minimum (fixed requirement)
• Mounting Type: Surface Mount (fixed requirement)
• Shielding Configuration: Unshielded (fixed requirement)

The substitute parts identified maintain these core electrical and mechanical specifications. Variations in DC resistance, Q factor, self-resonant frequency, core material, inductance tolerance, operating temperature range, and RoHS compliance status are permissible within the scope of substitution, provided the critical parameters remain constant.

Parameter Comparison

Engineering Selection Recommendations

PM0805-6N8M-RC is the direct manufacturer equivalent from Bourns Inc. This part maintains the same base product series (PM0805) and offers active product status with ROHS3 compliance. The DC resistance is reduced to 60 mOhm compared to the original 110 mOhm specification, resulting in improved Q factor (60 versus 50 at 1 GHz) and higher self-resonant frequency (5.8 GHz versus 5.5 GHz). The operating temperature range is narrowed to -40°C ~ 125°C. This substitute is recommended for applications where RoHS3 compliance is required and the lower operating temperature floor is acceptable.

CW201212-6N8J is an alternative from Bourns Inc. within the CW201212 series. This part also provides active product status and ROHS3 compliance. It features tighter inductance tolerance (±5% versus ±20%), identical DC resistance (60 mOhm), and matching Q factor and self-resonant frequency to PM0805-6N8M-RC. The operating temperature range is identical to PM0805-6N8M-RC at -40°C ~ 125°C. This substitute is suitable for applications requiring improved inductance accuracy.

Both substitute parts are available in Tape & Reel packaging, supporting automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can PM0805-6N8M-RC be used as a direct replacement for PM0805-6N8M?

A: Yes. Both parts share identical inductance (6.8 nH), current rating (600 mA), package (0805 / 2012 Metric), and mounting type (Surface Mount). The primary differences are reduced DC resistance (60 mOhm versus 110 mOhm), improved Q factor, higher self-resonant frequency, narrowed operating temperature range (-40°C to 125°C versus -55°C to 125°C), and ROHS3 compliance status.

Q: What is the difference between PM0805-6N8M-RC and CW201212-6N8J?

A: Both parts meet the core substitution criteria with identical inductance, current rating, and package specifications. The CW201212-6N8J offers tighter inductance tolerance (±5% versus ±20%), which may be beneficial for precision applications. Both share the same DC resistance (60 mOhm), Q factor (60 @ 1 GHz), self-resonant frequency (5.8 GHz), and operating temperature range (-40°C ~ 125°C).

Q: Are there packaging differences between these parts?

A: The original PM0805-6N8M packaging specification is not detailed in the available data. Both substitute parts (PM0805-6N8M-RC and CW201212-6N8J) are supplied in Tape & Reel (TR) packaging, which is standard for automated surface mount assembly.

Q: Does the lower DC resistance of the substitute parts affect circuit performance?

A: The substitute parts feature 60 mOhm DC resistance compared to the original 110 mOhm specification. Lower DC resistance reduces resistive losses in the inductor, resulting in improved efficiency and higher Q factor. This change is generally beneficial for circuit performance.

Q: What is the impact of the narrowed operating temperature range in the substitute parts?

A: The substitute parts operate from -40°C to 125°C, compared to the original -55°C to 125°C range. Applications requiring operation below -40°C cannot use these substitutes. For applications within the -40°C to 125°C range, this specification change has no impact.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both PM0805-6N8M-RC and CW201212-6N8J are ROHS3 compliant, whereas the original PM0805-6N8M is RoHS non-compliant. This compliance upgrade is beneficial for applications subject to RoHS regulations.
