Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VLS252010ET-R68N is determined by the following critical parameters:

• Inductance value of 680 nH
• Shielded ferrite drum core construction
• Surface mount 1008 (2520 Metric) package footprint
• Physical dimensions of 2.50mm L × 2.00mm W × 1.00mm H (maximum seated height)
• Current rating capability of 2.05 A or greater
• DC resistance of 62 mOhm or lower
• ROHS3 compliance and MSL 1 rating

The three substitute parts listed meet these core electrical and mechanical requirements while offering improved specifications in current rating and DC resistance characteristics.

Parameter Comparison

Engineering Selection Recommendations

VLS252010CX-R68M-1 is the primary equivalent from TDK Corporation's active product line. This part maintains identical inductance, shielding, and core material specifications while offering improved current rating (2.62 A versus 2.05 A) and reduced DC resistance (50 mOhm versus 62 mOhm). The part is classified as Active status and ROHS3 compliant. Package designation is listed as Nonstandard with 2520 supplier device package, requiring verification of PCB footprint compatibility despite matching physical dimensions.

BWVC00252012R68M00 and BWVC00252012R68T00 are Pulse Electronics alternatives that provide the lowest DC resistance (35 mOhm) and highest current saturation rating (2.52 A). Both parts are Active status and ROHS3 compliant. The seated height is 1.25mm compared to 1.00mm for the original part, and operating temperature range extends to -55°C ~ 125°C. BWVC00252012R68M00 features ±20% tolerance, while BWVC00252012R68T00 matches the original ±30% tolerance specification.

All substitute parts maintain ferrite core construction, shielding, surface mount configuration, and MSL 1 rating. Selection should account for PCB layout constraints related to seated height differences and specific tolerance requirements for the application circuit.

Frequently Asked Questions (FAQ)

Q: Can VLS252010CX-R68M-1 be used as a direct replacement for VLS252010ET-R68N?

A: VLS252010CX-R68M-1 meets the core electrical requirements with superior current rating and lower DC resistance. However, the package designation differs (Nonstandard versus standard 1008), requiring confirmation that PCB footprint and assembly process compatibility are maintained.

Q: What is the impact of the 0.25mm height difference between the original part and Pulse Electronics substitutes?

A: BWVC00252012R68M00 and BWVC00252012R68T00 have a maximum seated height of 1.25mm compared to 1.00mm for VLS252010ET-R68N. This difference must be evaluated against PCB clearance requirements, component stacking constraints, and assembly process specifications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. VLS252010CX-R68M-1, BWVC00252012R68M00, and BWVC00252012R68T00 are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's environmental compliance profile.

Q: Which substitute offers the best DC resistance performance?

A: BWVC00252012R68M00 and BWVC00252012R68T00 both provide 35 mOhm DC resistance, representing a 44% reduction compared to the original 62 mOhm specification. This results in lower power dissipation and improved thermal performance in high-current applications.

Q: What is the difference between BWVC00252012R68M00 and BWVC00252012R68T00?

A: Both parts are electrically and mechanically identical with the exception of inductance tolerance. BWVC00252012R68M00 specifies ±20% tolerance, while BWVC00252012R68T00 specifies ±30% tolerance, matching the original VLS252010ET-R68N tolerance specification.

Q: Do all substitute parts support the same operating temperature range?

A: No. VLS252010ET-R68N and VLS252010CX-R68M-1 operate from -40°C to 105°C. BWVC00252012R68M00 and BWVC00252012R68T00 extend the range to -55°C to 125°C, providing enhanced performance in extreme temperature environments.
