1210HS-561EMFS Equivalent & Substitute Parts

Part Overview

The 1210HS-561EMFS is a 560 nH unshielded drum core wirewound inductor manufactured by Delta Electronics/Components, rated for 530 mA continuous current with 250 mOhm DC resistance. This surface mount component is packaged in the 1210 (3225 Metric) form factor and operates across the -40°C to 85°C temperature range.

The 1210HS-561EMFS is classified as obsolete. Substitute parts are necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades where this inductor specification is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1210HS-561EMFS is determined by the following critical parameters:

Mandatory Matching Criteria:

• Inductance value: 560 nH
• Package / Case: 1210 (3225 Metric)
• Mounting Type: Surface Mount
• Shielding: Unshielded

Allowable Parameter Variations:

• Current Rating: Substitute parts rated at 450 mA are acceptable for applications where the original 530 mA rating is not a hard requirement
• DC Resistance: Substitute parts with DCR up to 550 mOhm are acceptable, representing a tolerance band relative to the original 250 mOhm specification
• Inductance Tolerance: Substitute parts with tighter tolerances (±5% to ±10%) are acceptable
• Operating Temperature Range: Substitute parts with extended or equivalent temperature ranges are acceptable
• Core Material: Both ferrite and iron powder cores are acceptable for this inductance value and package
• Self Resonant Frequency: Substitute parts with lower SRF (180 MHz vs. 250 MHz) are acceptable

Three substitute parts meet these criteria and are listed below.

Engineering Selection Recommendations

IMC1210ERR56K (Vishay Dale)

This substitute is an active product with ROHS3 compliance and unlimited MSL rating. The iron powder core construction provides extended operating temperature range (-55°C to 125°C) compared to the original part. Current rating is reduced to 450 mA and DCR increases to 550 mOhm maximum. Inductance tolerance is ±10%, representing improved specification control. This part is suitable for applications where the extended temperature range and active product status are prioritized over the original current rating.

NLV32T-R56J-EF (TDK Corporation)

This substitute is an active product with ROHS3 compliance, unlimited MSL rating, and ferrite core construction matching the original part material. Operating temperature range extends to 105°C. Inductance tolerance is ±5%, providing tighter specification control than the original ±20%. Current rating is 450 mA and DCR is 550 mOhm maximum. REACH status is affected. This part is suitable for applications requiring ferrite core characteristics and improved inductance tolerance.

NLV32T-R56J-EFD (TDK Corporation)

This substitute is an active product with ROHS3 compliance, unlimited MSL rating, ferrite core construction, and AEC-Q200 automotive qualification. Operating temperature range is -40°C to 105°C. Inductance tolerance is ±5%. Current rating is 450 mA and DCR is 550 mOhm maximum. REACH status is affected. This part is suitable for applications requiring automotive-grade reliability and ferrite core characteristics with improved inductance tolerance.

Frequently Asked Questions (FAQ)

Q: Can the 1210HS-561EMFS be directly replaced with any of these substitute parts?

A: Direct replacement is possible only if the application does not require the original 530 mA current rating. All substitute parts are rated for 450 mA maximum continuous current. If the circuit design operates below 450 mA, substitution is compatible. If the circuit requires 530 mA or higher, substitution is not recommended.

Q: What is the impact of increased DC resistance in the substitute parts?

A: The substitute parts have DCR of 550 mOhm maximum compared to the original 250 mOhm. This represents a 2.2x increase in series resistance. In circuits where inductor losses are critical, this increased DCR will result in higher power dissipation and reduced circuit efficiency. Thermal analysis is required for applications sensitive to inductor losses.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All substitute parts use the 1210 (3225 Metric) surface mount package with identical mounting type. Physical dimensions are equivalent, with minor variations in length and width within the 1210 package specification. All parts are supplied in Tape & Reel (TR) packaging format.

Q: What is the difference between the two TDK substitute parts?

A: NLV32T-R56J-EF and NLV32T-R56J-EFD are electrically identical with matching inductance, current rating, DCR, and operating temperature range. The primary difference is that NLV32T-R56J-EFD carries AEC-Q200 automotive qualification, making it suitable for automotive applications requiring this certification. Both parts have REACH-affected status.

Q: Which substitute part has the best inductance tolerance?

A: Both TDK parts (NLV32T-R56J-EF and NLV32T-R56J-EFD) offer ±5% inductance tolerance, compared to ±10% for the Vishay Dale part and ±20% for the original. Tighter tolerance provides better circuit performance in applications where inductance value precision is critical.

Q: Does the core material difference affect substitution compatibility?

A: Core material differences (ferrite vs. iron powder) affect frequency response characteristics and Q factor. The original part uses ferrite with Q of 35 at 25.2 MHz and SRF of 250 MHz. The Vishay Dale substitute uses iron powder with Q of 30 and SRF of 180 MHz. TDK substitutes use ferrite with Q of 30 and SRF of 180 MHz. For applications operating near the self-resonant frequency or requiring specific Q characteristics, core material selection is significant.

Q: What is the inventory status of these substitute parts?

A: IMC1210ERR56K has 1,145 pieces in stock. NLV32T-R56J-EF has 9,417 pieces in stock. NLV32T-R56J-EFD has 18,978 pieces in stock. The TDK NLV32T-R56J-EFD variant has the highest inventory availability.
