Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1210-272J is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• Inductance: 2.7 µH
• Inductance Tolerance: ±5%
• Current Rating: 411 mA
• DC Resistance: 1.1 Ohm Max
• Q @ Frequency: 30 @ 7.9 MHz
• Self Resonant Frequency: 65 MHz

Mechanical Parameters (Must Match):

• Package / Case: 1210 (3225 Metric)
• Mounting Type: Surface Mount
• Physical Dimensions: 0.128" L x 0.095" W (3.25mm x 2.42mm)
• Height - Seated (Max): 0.101" (2.57mm)

Environmental Parameters (Must Match):

• Operating Temperature Range: -55°C ~ 125°C
• Core Material: Ferrite
• Shielding: Unshielded
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part 1210R-272J meets all electrical, mechanical, and environmental specifications. The primary distinction is the RoHS compliance status, which may be required for specific applications or regulatory jurisdictions.

Parameter Comparison

Engineering Selection Recommendations

1210-272J Selection Criteria: The 1210-272J is appropriate for applications where RoHS non-compliance is acceptable or where legacy component specifications are required. This part maintains Active product status with established inventory availability.

1210R-272J Selection Criteria: The 1210R-272J is the preferred substitute for applications requiring ROHS3 compliance. This variant is manufactured by the same supplier (API Delevan Inc.) and maintains identical electrical and mechanical specifications. The 1210R-272J offers higher inventory availability (1812 pieces versus 1098 pieces) and satisfies regulatory requirements for RoHS3 compliant assemblies.

Both parts are Active products with unlimited moisture sensitivity tolerance (MSL 1), suitable for standard storage and handling conditions.

Frequently Asked Questions (FAQ)

Q: Can the 1210R-272J directly replace the 1210-272J in existing designs?

A: Yes. The 1210R-272J is a direct electrical and mechanical equivalent. All critical parameters including inductance (2.7 µH), current rating (411 mA), DC resistance (1.1 Ohm Max), and package dimensions (1210 / 3225 Metric) are identical. The primary difference is RoHS3 compliance status.

Q: What is the significance of the "R" designation in the 1210R-272J part number?

A: The "R" designation indicates the RoHS3 compliant variant within the 1210 series. This denotes compliance with Restriction of Hazardous Substances regulations. All other specifications remain equivalent to the non-R variant.

Q: Are there any performance differences between 1210-272J and 1210R-272J?

A: No. Both parts share identical electrical performance characteristics: 2.7 µH inductance, 30 Q factor at 7.9 MHz, 65 MHz self-resonant frequency, and -55°C to 125°C operating temperature range.

Q: Which part should be selected for new designs?

A: For new designs, the 1210R-272J is recommended due to ROHS3 compliance and higher inventory availability. The 1210-272J remains suitable for applications where RoHS compliance is not a requirement.

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

A: Yes. Both the 1210-272J and 1210R-272J are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.

Q: What is the moisture sensitivity classification for these inductors?

A: Both parts carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions. Standard storage and handling procedures apply.
