Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VLS252010HBX-4R7M-1 is determined by the following critical parameters:

• Inductance Value: Must be 4.7 µH with ±20% tolerance
• Shielding Type: Must be shielded to maintain electromagnetic isolation
• Core Type: Drum core wirewound construction
• Current Rating: Minimum 1.09 A continuous current capability
• Saturation Current: Minimum 1.6 A
• DC Resistance: Maximum 260 mOhm (allowing minor variance from the 250 mOhm specification)
• Mounting: Surface mount configuration
• Temperature Range: Operating capability within or exceeding -40°C to 105°C
• Compliance: RoHS3 compliant status

The PA4335.472NLT meets these substitution criteria with equivalent inductance, shielding, core type, and current handling characteristics. Differences in package dimensions and core material (iron vs. metal) do not preclude substitution when mechanical fit and thermal performance are verified for the specific application.

Parameter Comparison

Engineering Selection Recommendations

Both the VLS252010HBX-4R7M-1 and PA4335.472NLT maintain Active product status and are RoHS3 compliant with REACH unaffected classification. The PA4335.472NLT provides higher current rating capability (1.25 A vs. 1.09 A) and extended operating temperature range (-40°C to 125°C vs. -40°C to 105°C), making it suitable for applications requiring additional thermal margin. The DC resistance differential of 10 mOhm (260 mOhm vs. 250 mOhm maximum) is within acceptable engineering tolerance for most circuit applications. Both parts are classified under identical HTSUS and ECCN codes, confirming regulatory equivalence. Selection between these parts should be based on specific application requirements regarding current headroom, thermal environment, and mechanical package constraints.

Frequently Asked Questions (FAQ)

Q: Can PA4335.472NLT be used as a direct replacement for VLS252010HBX-4R7M-1?

A: Yes, provided that the mechanical package dimensions are compatible with the PCB layout. The PA4335.472NLT measures 0.106" L x 0.087" W x 0.047" H (seated), compared to the VLS252010HBX-4R7M-1 at 0.098" L x 0.079" W x 0.039" H (seated). Verify footprint clearance before implementation.

Q: What are the critical electrical parameters for substitution?

A: Inductance value (4.7 µH ±20%), shielding type (shielded), core construction (drum core wirewound), current rating (minimum 1.09 A), saturation current (minimum 1.6 A), and DC resistance (maximum 260 mOhm) are the determining factors for functional equivalence.

Q: How do the DC resistance values compare?

A: The VLS252010HBX-4R7M-1 specifies 250 mOhm maximum, while the PA4335.472NLT specifies 260 mOhm maximum. This 10 mOhm difference represents a 4% variance and is typically acceptable in circuit design unless the application has strict power dissipation constraints.

Q: Are there temperature range considerations?

A: The PA4335.472NLT operates to 125°C versus 105°C for the VLS252010HBX-4R7M-1. Applications operating near the upper temperature limit of the TDK part may benefit from the extended range of the Pulse Electronics substitute.

Q: What packaging differences exist?

A: The VLS252010HBX-4R7M-1 is supplied in Cut Tape (CT) & Digi-Reel® packaging, while the PA4335.472NLT is supplied in Tape & Reel (TR) format. Both use standard surface mount tape configurations compatible with automated assembly equipment.

Q: Are both parts RoHS3 compliant?

A: Yes, both the VLS252010HBX-4R7M-1 and PA4335.472NLT are RoHS3 compliant with MSL rating of 1 (Unlimited) and REACH unaffected status, confirming regulatory equivalence for use in restricted substance environments.
