1210HS-682EMFS Equivalent & Substitute Parts

Part Overview

The 1210HS-682EMFS is a 6.8 µH unshielded drum core wirewound inductor manufactured by Delta Electronics/Components, rated for 240 mA continuous current with 1.5Ohm DC resistance. This surface mount component is housed in a 1210 (3225 Metric) package and operates across the temperature range of -40°C to 85°C.

The 1210HS-682EMFS is classified as obsolete. Equivalent and substitute parts are necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this inductance value and package format.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1210HS-682EMFS is determined by the following critical parameters:

Fixed Parameters (Must Match):

• Inductance value: 6.8 µH
• Inductance tolerance: ±20%
• Package / Case: 1210 (3225 Metric)
• Core type: Ferrite drum core, wirewound
• Shielding: Unshielded
• Mounting type: Surface mount
• RoHS3 compliance
• MSL 1 rating

Variable Parameters (Allowable Substitution Range):

• Current rating: Substitute parts must equal or exceed 240 mA
• DC resistance: Substitute parts may vary based on current rating and design
• Operating temperature: Substitute parts must support minimum -40°C to 85°C range
• Frequency characteristics: May vary between substitute parts

All four substitute parts meet the fixed parameter requirements and provide equal or superior current handling capability compared to the original 1210HS-682EMFS.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

The 744032006 (Würth Elektronik WE-LQ series) and NLCV32T-6R8M-EFRD (TDK NLCV-EFD series) are the preferred substitutes. Both parts are classified as active products with current manufacturing support. The NLCV32T-6R8M-EFRD offers extended temperature range (-40°C to 125°C) and AEC-Q200 automotive qualification, providing enhanced reliability for demanding applications. The 744032006 provides a cost-effective alternative with active product status and extended temperature capability.

Secondary Substitute (Active Product Status):

The NLCV32T-6R8M-EF (TDK NLCV-EF series) is an active product offering 530 mA current rating with compatible electrical and mechanical specifications. This part is suitable for applications where the extended temperature range of the EFRD variant is not required.

Alternative Substitute (Not For New Designs):

The BRL3225T6R8M (Taiyo Yuden BR series) is classified as "Not For New Designs" and should be used only for legacy system maintenance or repair applications where design continuity with existing inventory is necessary. This part offers the highest current rating (770 mA) among all substitutes.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and compatibility with the 1210 (3225 Metric) surface mount package format.

Frequently Asked Questions (FAQ)

Q: Can the 1210HS-682EMFS be directly replaced with any of these substitute parts?

A: Yes. All four substitute parts maintain the same 6.8 µH inductance value, ±20% tolerance, 1210 (3225 Metric) package format, ferrite drum core construction, unshielded design, and surface mount configuration. All parts are ROHS3 compliant with MSL 1 rating. The substitute parts provide equal or superior current handling capability.

Q: What is the primary difference between the substitute parts?

A: The substitute parts differ in current rating, DC resistance, operating temperature range, and product status. The 744032006 and NLCV32T-6R8M-EFRD offer active product status with extended temperature ranges. The NLCV32T-6R8M-EF provides an active alternative with standard temperature range. The BRL3225T6R8M is classified as "Not For New Designs" but offers the highest current rating.

Q: Which substitute part should be selected for new designs?

A: For new designs, select either the 744032006 (Würth Elektronik) or NLCV32T-6R8M-EFRD (TDK). Both are active products with full manufacturing support. The NLCV32T-6R8M-EFRD is recommended for applications requiring extended temperature operation (-40°C to 125°C) or automotive qualification (AEC-Q200).

Q: Are there mechanical compatibility concerns when substituting these parts?

A: All substitute parts use the 1210 (3225 Metric) package format with surface mount configuration. Physical dimensions are comparable across all parts, with maximum seated heights ranging from 0.067" to 0.094". Verify PCB footprint compatibility with your specific design layout, as minor dimensional variations exist between manufacturers.

Q: What is the impact of DC resistance differences on circuit performance?

A: The 1210HS-682EMFS has 1.5Ohm DC resistance, while substitute parts range from 324mOhm to 400mOhm. Lower DC resistance in substitute parts reduces resistive losses and heat generation. Circuit designs must account for this parameter difference if the original 1.5Ohm resistance was a critical design specification.

Q: Can the BRL3225T6R8M be used in new production?

A: The BRL3225T6R8M is classified as "Not For New Designs." This part should be used only for legacy system maintenance, repair, or applications where design continuity with existing inventory is required. For new production, select an active product status substitute.

Q: Are all substitute parts suitable for the full operating temperature range of the original part?

A: All substitute parts support the minimum required range of -40°C to 85°C. The 744032006 and NLCV32T-6R8M-EFRD extend this range to -40°C to 125°C, providing additional thermal margin. The BRL3225T6R8M and NLCV32T-6R8M-EF support -40°C to 105°C. Verify that your application requirements align with the selected substitute's temperature specification.
