Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

• Inductance Value: 3.3 nH nominal (tolerance ±0.3nH acceptable)
• Package / Case: 0603 (1608 Metric) surface mount only
• Shielding Configuration: Unshielded
• Current Rating: Minimum 500 mA required
• DC Resistance: Maximum 120mOhm preferred; higher values acceptable if circuit design permits
• Operating Temperature: Minimum -40°C ~ 85°C range required

Substitute parts are grouped into two categories:

Category A - Direct Electrical Equivalents (3.3 nH):

• B82496C3339A000
• B82496C3339Z000

Category B - Near-Value Alternatives (3.9 nH):

• B82496C3399J000
• B82496C3399Z000

Category C - Reduced Current Rating (3.3 nH, 300 mA):

• CI160808-3N3D

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Recommended for New Designs):

B82496C3339A000 and B82496C3339Z000 are the preferred alternatives. Both maintain the 3.3 nH inductance specification with improved electrical performance (lower DCR, higher Q factor, extended SRF). Current rating of 1.2 A exceeds the original 500 mA requirement. Both parts are active products with AEC-Q200 certification and ROHS3 compliance. The primary distinction is tolerance specification: B82496C3339A000 carries ±0.3nH tolerance matching the original part, while B82496C3339Z000 offers tighter ±0.2nH tolerance. Both are packaged in 0603 (1608 Metric) with identical footprint dimensions.

Secondary Substitutes (Inductance Deviation):

B82496C3399J000 and B82496C3399Z000 provide 3.9 nH inductance, representing an 18% increase from the 3.3 nH specification. These parts are suitable only when circuit design permits inductance variation within this range. Both are active AEC-Q200 certified products with ROHS3 compliance. Current rating of 1.1 A exceeds the original 500 mA requirement. B82496C3399Z000 offers tighter ±0.2nH tolerance compared to B82496C3399J000 (±5%).

Not Recommended for New Designs:

CI160808-3N3D is classified as "Not For New Designs" and carries reduced current rating of 300 mA, below the original 500 mA specification. Additionally, DCR of 220mOhm exceeds the original 120mOhm maximum. This part is suitable only for legacy design maintenance where inductance value and package compatibility are the sole requirements.

Frequently Asked Questions (FAQ)

Q: Can B82496C3339A000 or B82496C3339Z000 be used as direct drop-in replacements for ELJ-RE3N3DF2?

A: Yes, both parts are direct electrical and mechanical equivalents. They maintain 3.3 nH inductance, 0603 (1608 Metric) package, and unshielded configuration. Both exceed the original current rating and provide superior electrical characteristics. Footprint compatibility is confirmed.

Q: What is the difference between B82496C3339A000 and B82496C3339Z000?

A: Both parts are electrically identical with the same inductance value, current rating, and performance characteristics. The distinction is inductance tolerance: B82496C3339A000 specifies ±0.3nH, while B82496C3339Z000 specifies ±0.2nH. Selection depends on circuit tolerance requirements.

Q: Can the 3.9 nH parts (B82496C3399J000 or B82496C3399Z000) be used as substitutes?

A: These parts are suitable only if circuit design permits an 18% inductance increase. The 3.9 nH value deviates from the original 3.3 nH specification and may affect circuit performance in frequency-dependent applications. Electrical validation is required before implementation.

Q: Why is CI160808-3N3D not recommended?

A: CI160808-3N3D is designated "Not For New Designs" by the manufacturer. Additionally, its 300 mA current rating falls below the original 500 mA specification, and DCR of 220mOhm exceeds the 120mOhm maximum. This part is suitable only for legacy maintenance applications.

Q: Are all substitute parts RoHS compliant?

A: The original ELJ-RE3N3DF2 is RoHS non-compliant. All recommended substitutes (B82496C3339A000, B82496C3339Z000, B82496C3399J000, B82496C3399Z000) are ROHS3 compliant. CI160808-3N3D is also ROHS3 compliant. Compliance verification with your procurement requirements is necessary.

Q: What is the operating temperature range difference?

A: The original part operates -40°C ~ 85°C. All EPCOS-TDK substitutes extend this to -55°C ~ 150°C, providing broader thermal operating margin. CI160808-3N3D operates -55°C ~ 125°C. Verify that extended temperature ranges do not conflict with application requirements.

Q: Are these parts available in the same packaging format?

A: Yes, all substitute parts are supplied in 0603 (1608 Metric) surface mount package with identical footprint dimensions (0.063" L x 0.031" W / 1.60mm x 0.80mm). Height variations are minimal (0.031" to 0.037" seated height), within standard PCB assembly tolerances.
