Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MLP2520P4R7S is determined by the following criteria:

Primary Matching Parameters:

• Inductance value: 4.7 µH (exact match required)
• Package / Case: 1008 (2520 Metric) (exact match required)
• Shielding: Shielded (exact match required)
• Tolerance: ±20% (exact match required)
• Operating Temperature Range: -40°C ~ 125°C (minimum requirement)
• RoHS3 Compliance: Required

Secondary Compatibility Parameters:

• Current Rating: Minimum 1.2 A (equal or greater acceptable)
• DC Resistance: Maximum 195mOhm (equal or lower acceptable)
• Mounting Type: Surface Mount (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

All three substitute parts meet the primary matching criteria. Variations in current rating and DC resistance are acceptable when the substitute part meets or exceeds the performance envelope of the original specification.

Parameter Comparison

Engineering Selection Recommendations

MLP2520S4R7ST0S1 is the primary recommended substitute. This part maintains identical electrical specifications to the original MLP2520P4R7S with the exception of current rating (1 A versus 1.2 A) and DC resistance (143mOhm versus 195mOhm). The lower DC resistance provides improved performance characteristics. Product status is active with ROHS3 compliance and MSL 1 rating. This part is suitable for applications where the 1 A current rating is sufficient.

VLS252012HBX-4R7M-1 is an alternative substitute offering superior current handling capability at 1.55 A, exceeding the original specification. This part features a metal drum core wirewound construction compared to the ferrite multilayer design of the original. DC resistance is 240mOhm, within acceptable limits. Operating temperature range is -40°C ~ 105°C, which is narrower than the original specification. Product status is active with ROHS3 compliance and MSL 1 rating. This part is suitable for applications requiring higher current capacity.

MLP2520V4R7ST0S1 is a secondary substitute option with reduced current rating (800 mA) and elevated DC resistance (286mOhm). This part is suitable only for applications where current requirements do not exceed 800 mA. Product status is active with ROHS3 compliance and MSL 1 rating.

All substitute parts maintain identical package dimensions, shielding characteristics, inductance value, and tolerance specifications. Selection should be based on specific application current requirements and thermal operating conditions.

Frequently Asked Questions (FAQ)

Q: Can MLP2520S4R7ST0S1 be used as a direct replacement for MLP2520P4R7S?

A: MLP2520S4R7ST0S1 is functionally compatible when application current requirements do not exceed 1 A. The lower current rating and improved DC resistance (143mOhm versus 195mOhm) make this part suitable for most applications. Both parts share identical inductance, package, shielding, and operating temperature specifications.

Q: What is the difference between MLP2520S4R7ST0S1 and VLS252012HBX-4R7M-1?

A: MLP2520S4R7ST0S1 is a multilayer inductor with ferrite core, while VLS252012HBX-4R7M-1 is a drum core wirewound inductor with metal core. VLS252012HBX-4R7M-1 provides higher current capacity (1.55 A) but operates at a narrower temperature range (-40°C ~ 105°C versus -40°C ~ 125°C). Both maintain the same 4.7 µH inductance and 1008 package format.

Q: Is MLP2520V4R7ST0S1 suitable for all applications using MLP2520P4R7S?

A: MLP2520V4R7ST0S1 is suitable only for applications where sustained current does not exceed 800 mA. The elevated DC resistance (286mOhm) may result in increased power dissipation compared to the original specification. This part should be selected only when current requirements are confirmed to be within its 800 mA rating.

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

A: All substitute parts are available in 1008 (2520 Metric) surface mount package with identical physical dimensions (0.098" L x 0.079" W, 0.047" max height). Packaging options differ: MLP2520S4R7ST0S1 and MLP2520V4R7ST0S1 are supplied in Tape & Reel (TR) format, while VLS252012HBX-4R7M-1 is supplied in Cut Tape (CT) & Digi-Reel® format.

Q: Do all substitute parts meet RoHS3 compliance?

A: All substitute parts are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the original MLP2520P4R7S specifications.
