1210-333J Fixed Inductor Equivalent & Substitute Parts

Part Overview

The 1210-333J is a fixed unshielded surface mount inductor manufactured by API Delevan Inc. with an inductance value of 33 µH, rated for 182 mA maximum current, and a DC resistance of 5.6 Ohm maximum. This component is classified as Active product status and is suitable for general-purpose RF and power applications requiring compact form factor inductors in the 1210 (3225 Metric) package.

Substitute parts become necessary when the primary part number experiences supply constraints, when design requirements mandate specific compliance certifications, or when inventory availability necessitates alternative sourcing from the same manufacturer's product line.

Substitute Part Grouping Explanation

Substitution of the 1210-333J with alternative part numbers is determined by strict equivalence across the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Inductance value: 33 µH
• Inductance tolerance: ±5%
• Current rating: 182 mA minimum
• DC resistance: 5.6 Ohm maximum
• Q factor @ 2.5 MHz: 30
• Self resonant frequency: 15 MHz
• Operating temperature range: -55°C to 125°C

Mechanical Equivalence Criteria:

• Package / Case: 1210 (3225 Metric)
• Mounting type: Surface Mount
• Core material: Ferrite
• Shielding configuration: Unshielded

Compliance Considerations:

• RoHS status
• REACH status
• Moisture sensitivity level

The 1210R-333J is classified as a direct substitute because it maintains identical electrical specifications and mechanical dimensions while differing only in RoHS compliance status and series designation.

Parameter Comparison

Engineering Selection Recommendations

1210-333J Selection Criteria: The 1210-333J is appropriate for applications where RoHS non-compliance is acceptable or where legacy design specifications explicitly reference this part number. Current inventory availability is 841 pieces.

1210R-333J Selection Criteria: The 1210R-333J is the preferred substitute when ROHS3 compliance is a design or regulatory requirement. This part maintains complete electrical and mechanical equivalence to the 1210-333J while meeting RoHS3 standards. Higher inventory availability of 4,100 pieces supports extended production runs and supply chain continuity. Both parts share identical series designation within the API Delevan 1210 product family and are classified as Active status.

Compliance Consideration: Selection between these two part numbers should be driven by the target application's regulatory environment and compliance requirements. The ROHS3 compliance of the 1210R-333J makes it suitable for applications destined for markets with mandatory RoHS directives, while the 1210-333J remains viable for applications without such constraints.

Frequently Asked Questions (FAQ)

Q: Are the 1210-333J and 1210R-333J electrically identical?

A: Yes. Both parts have identical inductance (33 µH), current rating (182 mA), DC resistance (5.6 Ohm maximum), Q factor (30 @ 2.5 MHz), and self resonant frequency (15 MHz). They operate across the same temperature range (-55°C to 125°C) and share identical electrical performance characteristics.

Q: Can the 1210R-333J be used as a direct replacement for the 1210-333J in existing designs?

A: Yes. The 1210R-333J is mechanically and electrically equivalent to the 1210-333J. Both use the 1210 (3225 Metric) package with identical dimensions (0.128" L x 0.095" W, height 0.101" maximum) and mounting type (Surface Mount). No PCB layout modifications are required.

Q: What is the primary difference between these two part numbers?

A: The primary difference is RoHS compliance status. The 1210-333J is RoHS non-compliant, while the 1210R-333J is ROHS3 compliant. All other specifications, including electrical performance, mechanical dimensions, and environmental ratings, are identical.

Q: Which part should be selected for new designs?

A: Selection depends on the target application's regulatory requirements. For applications requiring RoHS3 compliance, the 1210R-333J is the appropriate choice. For applications without RoHS compliance mandates, either part is suitable based on availability and supply chain considerations.

Q: Are there any performance differences between the two parts?

A: No. Both parts deliver identical performance across all specified electrical parameters including inductance tolerance (±5%), Q factor, self resonant frequency, and operating temperature range (-55°C to 125°C).

Q: What is the moisture sensitivity level for both parts?

A: Both the 1210-333J and 1210R-333J have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without moisture control requirements.

Q: Are both parts available in Tape & Reel packaging?

A: Yes. Both the 1210-333J and 1210R-333J are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.
