VLS252012ET-3R3M Equivalent & Substitute Parts

Part Overview

The VLS252012ET-3R3M is a 3.3 µH shielded drum core wirewound inductor manufactured by TDK Corporation, rated for 980 mA continuous current with a maximum DC resistance of 272mOhm. This surface mount component is housed in a 1008 (2520 Metric) package and is classified as Not For New Designs. Due to this product status and limited design support, identifying equivalent substitute parts with compatible electrical and mechanical specifications is essential for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the VLS252012ET-3R3M are qualified based on the following critical parameters:

• Inductance value: 3.3 µH (exact match required)
• Inductance tolerance: ±20% or tighter
• Current rating: equal to or greater than 980 mA
• DC resistance: equal to or lower than 272 mOhm
• Core material: Ferrite
• Shielding: Shielded configuration
• Mounting type: Surface Mount
• Physical dimensions: 2.50mm x 2.00mm footprint compatibility
• Compliance: ROHS3 Compliant, MSL 1

The three substitute parts listed below meet these criteria with varying performance characteristics. Substitutes may differ in package designation, saturation current, and operating temperature range, provided the core electrical parameters remain within acceptable limits for the application.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are ROHS3 compliant with MSL 1 rating, matching the environmental and regulatory requirements of the original VLS252012ET-3R3M.

VLS252010CX-3R3M-1 (TDK Corporation, Active) provides the closest electrical performance match within the TDK product family. It maintains identical inductance and tolerance specifications with improved current handling (1.25 A vs. 980 mA) and reduced DC resistance (186 mOhm vs. 272 mOhm). Operating temperature range remains -40°C ~ 105°C. Height is reduced to 1.00mm, which may require PCB layout verification for clearance-sensitive applications.

BWVF002520123R3M00 (Pulse Electronics, Active) offers the lowest DC resistance at 130 mOhm with the highest current rating at 1.5 A. Extended operating temperature range (-55°C ~ 125°C) provides thermal margin. Inductance tolerance remains ±20%. Package designation is listed as Nonstandard; physical footprint remains 2.50mm x 2.00mm.

BWVF002520123R3T00 (Pulse Electronics, Active) provides equivalent performance to BWVF002520123R3M00 with standard 1008 (2520 Metric) package designation. Inductance tolerance is ±30%, which is wider than the original specification. Current rating is 1.35 A with 130 mOhm DC resistance. Extended operating temperature range (-55°C ~ 125°C) is maintained.

Frequently Asked Questions (FAQ)

Q: Can VLS252010CX-3R3M-1 be used as a direct replacement for VLS252012ET-3R3M?

A: Yes. Both parts share identical inductance (3.3 µH), tolerance (±20%), core material (Ferrite), shielding, and operating temperature range. The substitute has superior electrical performance with higher current rating and lower DC resistance. Height reduction from 1.20mm to 1.00mm requires verification that PCB clearance and component placement are compatible with the application.

Q: What are the key differences between the TDK and Pulse Electronics substitutes?

A: TDK VLS252010CX-3R3M-1 maintains the original operating temperature range (-40°C ~ 105°C) and offers moderate performance improvement. Pulse Electronics BWVF series parts provide extended temperature range (-55°C ~ 125°C), significantly lower DC resistance (130 mOhm), and higher current ratings (1.35 A to 1.5 A). BWVF002520123R3T00 uses standard 1008 package designation, while BWVF002520123R3M00 uses Nonstandard designation despite identical physical dimensions.

Q: Are there package compatibility concerns with these substitutes?

A: All substitutes maintain the 2.50mm x 2.00mm footprint required for 1008 (2520 Metric) PCB pads. Height variations range from 1.00mm to 1.25mm compared to the original 1.20mm. Applications with tight vertical clearance constraints must verify component height compatibility. BWVF002520123R3T00 explicitly uses 1008 (2520 Metric) package designation, while VLS252010CX-3R3M-1 and BWVF002520123R3M00 use alternative package designations but maintain identical footprint dimensions.

Q: Does inductance tolerance affect substitution suitability?

A: The original VLS252012ET-3R3M specifies ±20% inductance tolerance. VLS252010CX-3R3M-1 and BWVF002520123R3M00 maintain ±20% tolerance. BWVF002520123R3T00 has ±30% tolerance, which is wider. Applications requiring tighter inductance control should prioritize parts with ±20% tolerance. All parts are tested at 1 MHz per specification.

Q: What compliance certifications apply to all substitute parts?

A: All substitute parts are ROHS3 compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's regulatory and environmental compliance profile.
