S1210R-682G Equivalent & Substitute Parts

Part Overview

The S1210R-682G is a fixed surface mount inductor manufactured by API Delevan Inc. in the S1210R series. This shielded ferrite core inductor is rated for 6.8 µH inductance with a maximum DC resistance of 1.5 Ohm and supports a current rating of 328 mA. The component is designed for operation across the temperature range of -55°C to 125°C and is housed in a 1210 (3225 Metric) package format.

The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are necessary when primary inventory is unavailable or when tolerance specifications allow for alternative selections within the same electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the S1210R-682G is determined by strict alignment of core electrical and mechanical parameters. The following criteria establish valid substitute relationships:

Critical Parameters (Must Match Exactly):

• Inductance value: 6.8 µH
• Current rating: 328 mA
• DC resistance maximum: 1.5 Ohm
• Core material: Ferrite
• Shielding: Shielded
• Package format: 1210 (3225 Metric)
• Operating temperature range: -55°C ~ 125°C
• Mounting type: Surface Mount

Allowable Variation:

• Inductance tolerance: The S1210R-682G specifies ±2% tolerance. Substitute parts with ±10% tolerance remain functionally equivalent when the nominal inductance value of 6.8 µH is maintained, as the tolerance band encompasses the primary specification.

Compliance Requirements:

• RoHS3 compliance status must be maintained
• Moisture sensitivity level must be MSL 1 or equivalent

The S1210R-682K qualifies as a direct substitute based on these parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the S1210R-682G and S1210R-682K are Active products with full RoHS3 compliance and REACH Unaffected status, making them suitable for applications requiring regulatory compliance in industrial and commercial environments.

The S1210R-682G features a tighter inductance tolerance of ±2%, appropriate for applications requiring precise inductance values. The S1210R-682K provides a ±10% tolerance specification while maintaining identical electrical performance characteristics including current rating, DC resistance, Q factor, and self-resonant frequency.

Both parts are housed in the 1210 (3225 Metric) package with identical maximum seated height of 0.101" (2.57mm). Minor dimensional variations in length and width remain within the same package classification and do not affect PCB layout compatibility for standard 1210 footprints.

Selection between these parts should be based on tolerance requirements specific to the application circuit. When ±2% tolerance is mandatory, the S1210R-682G is the required selection. When ±10% tolerance is acceptable, the S1210R-682K provides equivalent functionality with higher current inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the S1210R-682K replace the S1210R-682G in all applications?

A: The S1210R-682K is electrically equivalent to the S1210R-682G for applications where inductance tolerance of ±10% is acceptable. Both parts maintain identical current rating (328 mA), DC resistance (1.5 Ohm max), and operating temperature range (-55°C ~ 125°C). Applications requiring tighter tolerance specifications must use the S1210R-682G with its ±2% tolerance rating.

Q: Are there PCB layout differences between these parts?

A: Both parts use the 1210 (3225 Metric) package format with identical maximum seated height (0.101" / 2.57mm). The S1210R-682K has slightly smaller length and width dimensions (0.128" L x 0.095" W versus 0.138" L x 0.105" W), but both fit standard 1210 footprints without layout modification.

Q: What compliance certifications apply to both parts?

A: Both the S1210R-682G and S1210R-682K are ROHS3 compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. Both are suitable for applications requiring regulatory compliance in regulated industries.

Q: Do these parts have identical electrical performance characteristics?

A: Yes. Both parts share identical Q factor (40 @ 7.9MHz), self-resonant frequency (35MHz), and inductance test frequency (7.9 MHz). The only electrical difference is inductance tolerance specification (±2% versus ±10%).

Q: What is the inventory status for each part?

A: The S1210R-682G has 1078 pieces in stock. The S1210R-682K has 2200 pieces in stock. Both are supplied in Tape & Reel (TR) packaging format.
