Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the VLF252012MT-2R2M are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Inductance value: 2.2 µH with ±20% tolerance
• Package / Case: 1008 (2520 Metric)
• Mounting Type: Surface Mount
• Shielding: Shielded configuration
• Physical dimensions: 0.098" L x 0.079" W (2.50mm x 2.00mm), Height 0.047" (1.20mm) maximum

Allowable Variation Parameters:

• Current Rating: Substitute parts must meet or exceed 1.67 A minimum requirement
• DC Resistance: Substitute parts must not exceed 100mOhm maximum
• Operating Temperature: Substitute parts must support minimum -40°C to 105°C range
• Moisture Sensitivity Level: MSL 1 (Unlimited)

The following parts satisfy these substitution criteria:

1. VLS252012HBX-2R2M-1 (TDK Corporation) – Direct manufacturer alternative with enhanced current rating
2. SRP2512-2R2M (Bourns Inc.) – Cross-manufacturer equivalent with improved saturation characteristics

Parameter Comparison

Engineering Selection Recommendations

VLS252012HBX-2R2M-1 (TDK Corporation): This substitute is the primary equivalent from the original manufacturer. It maintains identical inductance, tolerance, package dimensions, and operating temperature range. The part offers improved current rating (2.3 A vs. 1.67 A) and higher saturation current (2.04A vs. 940mA), providing enhanced performance margin. DC resistance remains within acceptable limits at 102mOhm maximum. The part is ROHS3 compliant and carries active product status with substantial inventory availability (110,736 pcs).

SRP2512-2R2M (Bourns Inc.): This cross-manufacturer substitute meets all critical electrical and mechanical parameters. It delivers 2.1 A current rating and 3A saturation current, exceeding the original part's specifications. The extended operating temperature range (-40°C to 125°C) provides additional thermal margin. DC resistance at 104mOhm maximum remains within acceptable tolerance. The part is ROHS3 compliant, carries active product status, and demonstrates high inventory availability (518,400 pcs). Q factor specification (39 @ 1MHz) is provided for this part.

Both substitutes are suitable for direct replacement in applications where the VLF252012MT-2R2M was originally specified, with the understanding that improved electrical performance characteristics may be realized.

Frequently Asked Questions (FAQ)

Q: Can VLS252012HBX-2R2M-1 and SRP2512-2R2M be used interchangeably with VLF252012MT-2R2M?

A: Both parts meet the critical substitution criteria: identical 2.2 µH inductance, ±20% tolerance, 1008 (2520 Metric) package, and shielded configuration. Both exceed the minimum 1.67 A current requirement and maintain DC resistance within specification. Physical dimensions and mounting characteristics are identical. They are electrically and mechanically compatible for direct replacement.

Q: What are the key differences between the two substitute parts?

A: VLS252012HBX-2R2M-1 is a TDK product with metal core construction, while SRP2512-2R2M is a Bourns product with iron powder core. SRP2512-2R2M offers higher saturation current (3A vs. 2.04A) and extended operating temperature range (-40°C to 125°C vs. -40°C to 105°C). Both are ROHS3 compliant and actively manufactured.

Q: Are there any compliance or certification differences?

A: Both substitute parts are ROHS3 compliant and REACH unaffected. Both carry EAR99 ECCN classification and 8504.50.4000 HTSUS code, matching the original part's regulatory status. Moisture Sensitivity Level is MSL 1 (Unlimited) for all three parts.

Q: What is the impact of higher current ratings in the substitute parts?

A: The substitute parts' higher current ratings (2.3 A and 2.1 A vs. 1.67 A) and saturation currents provide additional design margin and reduce thermal stress during operation. These improvements do not affect compatibility; they represent enhanced performance characteristics suitable for the same application space.

Q: Are package dimensions identical across all three parts?

A: Yes. All three parts use the 1008 (2520 Metric) package with identical dimensions: 0.098" L x 0.079" W (2.50mm x 2.00mm) and 0.047" (1.20mm) maximum seated height. PCB layout and assembly processes require no modification.
