Key Parameters

Substitute Part Grouping Explanation

Substitution of the S1210-682K is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• Inductance value: 6.8 µH
• Inductance tolerance: ±10%
• Current rating: 328 mA minimum
• DC resistance: 1.5 Ohm maximum
• Q factor: 40 @ 7.9 MHz
• Self resonant frequency: 35 MHz

Mechanical Parameters (Must Match):

• Package / Case: 1210 (3225 Metric)
• Shielding: Shielded
• Core material: Ferrite
• Mounting type: Surface Mount
• Physical dimensions: 0.128" L x 0.095" W (3.25mm x 2.42mm)
• Maximum seated height: 0.101" (2.57mm)

Environmental Parameters (Must Match):

• Operating temperature range: -55°C to 125°C
• Moisture sensitivity level: 1 (Unlimited)

The substitute part S1210R-682K meets all electrical, mechanical, and environmental specifications. The primary distinction between the main part and its substitute is the RoHS compliance status, which does not affect electrical or mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both the S1210-682K and S1210R-682K are active production parts from API Delevan Inc. with identical electrical and mechanical specifications. Selection between these parts is determined by regulatory and compliance requirements:

S1210-682K Selection Criteria:

• Applications where RoHS compliance is not mandated
• Legacy designs or systems with established part qualification
• Procurement scenarios where RoHS non-compliant components are acceptable

S1210R-682K Selection Criteria:

• Applications requiring ROHS3 compliance
• New designs targeting RoHS-compliant component specifications
• Supply chains or regions where RoHS compliance is mandatory
• Long-term product lifecycle management requiring compliant components

Both parts are REACH Unaffected and classified under ECCN EAR99 with HTSUS code 8504.50.8000. The S1210R-682K offers superior compliance positioning for modern manufacturing and regulatory environments while maintaining complete electrical and mechanical interchangeability with the S1210-682K.

Frequently Asked Questions (FAQ)

Q: Are S1210-682K and S1210R-682K electrically interchangeable?

A: Yes. Both parts have identical inductance (6.8 µH), current rating (328 mA), DC resistance (1.5 Ohm max), Q factor (40 @ 7.9 MHz), and self resonant frequency (35 MHz). They are direct electrical equivalents.

Q: Can S1210R-682K be used as a drop-in replacement for S1210-682K?

A: Yes. Both parts share identical mechanical specifications including package type (1210 / 3225 Metric), physical dimensions (0.128" L x 0.095" W), seated height (0.101" max), and mounting type (Surface Mount). PCB layout and assembly processes require no modification.

Q: What is the difference between S1210-682K and S1210R-682K?

A: The primary difference is RoHS compliance status. S1210-682K is RoHS non-compliant, while S1210R-682K is ROHS3 compliant. All electrical, mechanical, and environmental parameters are identical.

Q: Which part should be selected for new designs?

A: S1210R-682K is recommended for new designs due to ROHS3 compliance, which aligns with current regulatory requirements and supply chain standards. However, S1210-682K remains a valid selection if RoHS compliance is not a design requirement.

Q: Are there any temperature or frequency limitations that affect substitution?

A: No. Both parts operate across the identical temperature range (-55°C to 125°C) and maintain the same frequency characteristics (Q factor of 40 @ 7.9 MHz, self resonant frequency of 35 MHz). Substitution does not introduce thermal or frequency-related constraints.

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

A: Both S1210-682K and S1210R-682K have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited moisture tolerance. Standard handling and storage procedures apply without special moisture control requirements.

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

A: Yes. Both S1210-682K and S1210R-682K are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.
