0805-27NJ Equivalent & Substitute Parts

Part Overview

The 0805-27NJ is a 27 nH unshielded drum core wirewound inductor manufactured by API Delevan Inc., rated for 500 mA with a maximum DC resistance of 250 mOhm. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and production continuity. The part operates across a temperature range of -40°C to 125°C and is mounted as a surface mount device in a nonstandard package configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0805-27NJ is determined by the following critical parameters:

• Inductance Value: Must be 27 nH with ±5% tolerance
• Current Rating: Minimum 500 mA (equal or higher acceptable)
• DC Resistance: Maximum 250 mOhm (lower values acceptable)
• Core Material: Ceramic unshielded construction
• Mounting Type: Surface mount configuration
• Operating Temperature Range: -40°C to 125°C minimum
• Package Compatibility: 0805 form factor or equivalent footprint

Two substitute parts meet these criteria with varying degrees of parameter alignment and product status differences.

Parameter Comparison

Engineering Selection Recommendations

36502A27NJTDG (TE Connectivity Passive Product) provides the closest electrical match to the 0805-27NJ. This part maintains identical inductance, tolerance, current rating, and DC resistance specifications. The component is in active production status with ROHS3 compliance and AEC-Q200 automotive qualification, supporting long-term availability and regulatory requirements. The standard 0805 (2015 Metric) package format ensures compatibility with modern PCB design tools and manufacturing processes.

CW201212-27NJ (Bourns Inc.) offers enhanced electrical performance with 600 mA current rating and reduced DC resistance of 120 mOhm, providing improved thermal characteristics and lower power dissipation. This part is also in active production with ROHS3 compliance and REACH compliance documentation. The slightly smaller physical footprint (0.083" L x 0.059" W versus 0.090" L x 0.068" W) and higher self-resonant frequency (2.6 GHz) may require PCB layout verification for existing designs.

Both substitute parts satisfy the core electrical requirements of the obsolete 0805-27NJ and provide active product status with modern compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can the 36502A27NJTDG directly replace the 0805-27NJ without circuit modification?

A: Yes. The 36502A27NJTDG maintains identical electrical specifications for inductance, tolerance, current rating, and DC resistance. The standard 0805 package format is compatible with existing PCB footprints designed for the original part.

Q: What is the primary advantage of the CW201212-27NJ over the 36502A27NJTDG?

A: The CW201212-27NJ provides 600 mA current rating versus 500 mA and features reduced DC resistance of 120 mOhm compared to 250 mOhm maximum. These characteristics result in lower power dissipation and improved thermal performance in high-current applications.

Q: Are there physical footprint differences between the substitute parts?

A: Yes. The 36502A27NJTDG maintains the original 0.090" L x 0.068" W footprint. The CW201212-27NJ uses a slightly smaller 0.083" L x 0.059" W footprint. Both are 0805 form factor devices, but PCB layout verification is recommended when switching between these parts in space-constrained designs.

Q: What compliance certifications apply to the substitute parts?

A: Both 36502A27NJTDG and CW201212-27NJ are ROHS3 compliant. The 36502A27NJTDG carries AEC-Q200 automotive qualification. The CW201212-27NJ is REACH compliant. The original 0805-27NJ is RoHS non-compliant and REACH unaffected.

Q: Is the inductance tolerance identical across all three parts?

A: Yes. All three parts maintain ±5% inductance tolerance at the 250 MHz test frequency.
