PM0805-2N2M Equivalent & Substitute Parts

Part Overview

The PM0805-2N2M is a 2.2 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 current with a maximum DC resistance of 80mOhm and operates across a temperature range of -55°C to 125°C. The part is currently listed 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 PM0805-2N2M is determined by strict alignment across the following critical parameters:

• Inductance value: 2.2 nH (exact match required)
• Current rating: 600 mA minimum
• Package / Case: 0805 (2012 Metric) form factor
• Core type: Drum core, wirewound construction
• Shielding configuration: Unshielded
• Core material: Ceramic

The CW201212-2N2J meets all substitution criteria. While it exhibits improved DC resistance (60mOhm versus 80mOhm) and tighter inductance tolerance (±5% versus ±20%), these represent performance enhancements rather than deviations from the electrical and mechanical specifications required for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

The CW201212-2N2J is the qualified substitute for the obsolete PM0805-2N2M. Both components are manufactured by Bourns Inc. and share identical electrical and mechanical specifications across all critical parameters: inductance value, current rating, package form factor, and physical dimensions.

The CW201212-2N2J offers additional advantages in terms of product lifecycle status and regulatory compliance. As an active product, it ensures long-term availability and supply chain continuity. The component achieves ROHS3 compliance, whereas the PM0805-2N2M is non-compliant, making the substitute the appropriate choice for applications subject to RoHS requirements.

The improved DC resistance (60mOhm versus 80mOhm) and tighter inductance tolerance (±5% versus ±20%) of the CW201212-2N2J provide enhanced performance characteristics without introducing compatibility concerns. The operating temperature range of the substitute (-40°C to 125°C) covers the upper portion of the original part's range (-55°C to 125°C); applications requiring operation below -40°C must be evaluated separately.

Frequently Asked Questions (FAQ)

Q: Can the CW201212-2N2J be used as a direct replacement for the PM0805-2N2M?

A: Yes. Both components share identical inductance values (2.2 nH), current ratings (600 mA), package specifications (0805 / 2012 Metric), and physical dimensions. They are electrically and mechanically interchangeable.

Q: What are the key differences between these two parts?

A: The primary differences are product status and compliance certifications. The CW201212-2N2J is an active product with ROHS3 compliance, while the PM0805-2N2M is obsolete and RoHS non-compliant. The substitute also features lower DC resistance (60mOhm versus 80mOhm) and tighter inductance tolerance (±5% versus ±20%).

Q: Are there any temperature range limitations when substituting?

A: The CW201212-2N2J operates from -40°C to 125°C, whereas the PM0805-2N2M operates from -55°C to 125°C. Applications requiring operation below -40°C should be reviewed to confirm the substitute meets thermal requirements.

Q: Do both parts use the same packaging format?

A: Yes. Both the PM0805-2N2M and CW201212-2N2J are supplied in 0805 (2012 Metric) surface mount packages with identical physical dimensions (2.10mm L x 1.50mm W x 1.50mm H max). They are footprint-compatible.

Q: What is the moisture sensitivity level for these components?

A: Both parts carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are there any regulatory or compliance considerations?

A: The CW201212-2N2J is ROHS3 compliant and REACH unaffected, making it suitable for applications subject to these regulatory frameworks. The PM0805-2N2M is RoHS non-compliant and should not be used in applications requiring RoHS compliance.
