Substitute Part Grouping Explanation

Substitute parts for the UP5-680-R are classified based on strict alignment with core electrical and mechanical parameters. The substitution logic is based on the following criteria:

Primary Substitution Criteria:

• Inductance value: 68 µH (exact match required)
• Current rating: 2.3 A minimum
• DC resistance: 130 mOhm maximum
• Saturation current: 3.5 A minimum
• Mounting type: Surface Mount
• Packaging: Tape & Reel
• Inductance test frequency: 100 kHz

Acceptable Parameter Variations:

• Inductance tolerance: ±15% to ±20%
• Operating temperature range: Must encompass or extend the -25°C to 105°C baseline
• Physical dimensions: Nonstandard package with minor dimensional variance acceptable within assembly constraints
• Shielding configuration: Both shielded and unshielded variants are listed based on application flexibility

Parts are grouped as Direct or Similar substitutes based on the degree of parameter alignment with the main part specification.

Engineering Selection Recommendations

Direct Substitute: P0250.683NLT (Pulse Electronics)

The P0250.683NLT from Pulse Electronics represents a direct substitute with full parameter alignment. This part matches the 68 µH inductance, 2.3 A current rating, and 130 mOhm DC resistance specification. The tighter inductance tolerance of ±15% provides improved consistency compared to the ±20% tolerance of the main part. Operating temperature range extends to -40°C to 130°C, exceeding the baseline requirement. ROHS3 compliance and MSL 1 rating confirm regulatory alignment. Current inventory of 2,722 pieces supports production requirements.

Similar Substitute: ASPI-1306T-680M-T (Abracon LLC)

The ASPI-1306T-680M-T qualifies as a similar substitute with matching inductance, current rating, saturation current, and DC resistance. This ferrite drum core wirewound inductor maintains unshielded configuration and ±20% tolerance. Operating temperature range of -40°C to 85°C covers the baseline -25°C to 105°C requirement with lower temperature extension but reduced upper temperature limit. ROHS3 compliance and MSL 1 rating are confirmed. Inventory of 1,471 pieces is available.

Similar Substitute: 74459168 (Würth Elektronik)

The 74459168 from Würth Elektronik is classified as a similar substitute due to parameter deviations in current rating and saturation current. This shielded drum core wirewound inductor maintains 68 µH inductance and 130 mOhm DC resistance but operates at 2.2 A continuous current and 3.0 A saturation current, representing a 4.3% reduction in current capacity and 14.3% reduction in saturation current compared to the main part. DC resistance tolerance increases to 138 mOhm maximum. Operating temperature range of -40°C to 125°C extends baseline coverage. ROHS3 compliance and MSL 1 rating are confirmed. Inventory of 2,000 pieces is available. Shielded configuration may provide electromagnetic interference mitigation in specific applications.

All substitute parts maintain Active product status, RoHS compliance, and unlimited moisture sensitivity rating, confirming suitability for production environments with standard handling and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can P0250.683NLT replace UP5-680-R in all applications?

A: The P0250.683NLT meets or exceeds all electrical parameters of the UP5-680-R, including inductance, current rating, DC resistance, and saturation current. The ±15% inductance tolerance is tighter than the ±20% specification of the main part. Operating temperature range extends beyond the baseline requirement. Physical dimensions are within nonstandard package tolerances. This part functions as a direct substitute for the UP5-680-R.

Q: What are the limitations of using 74459168 as a substitute?

A: The 74459168 operates at 2.2 A continuous current versus the 2.3 A rating of the UP5-680-R, representing a 4.3% reduction in current capacity. Saturation current is 3.0 A compared to 3.5 A, a 14.3% reduction. DC resistance increases to 138 mOhm maximum from 130 mOhm. The shielded configuration differs from the unshielded design of the main part. These deviations require application-level verification to confirm compatibility with circuit current demands and electromagnetic environment requirements.

Q: Does ASPI-1306T-680M-T support the full operating temperature range of UP5-680-R?

A: The ASPI-1306T-680M-T operates from -40°C to 85°C. The UP5-680-R operates from -25°C to 105°C. The substitute part covers the lower temperature range with additional margin but does not extend to the 105°C upper limit of the main part. Applications requiring operation above 85°C require confirmation that the ASPI-1306T-680M-T meets thermal performance requirements.

Q: Are all substitute parts available in Tape & Reel packaging?

A: All substitute parts listed—P0250.683NLT, 74459168, and ASPI-1306T-680M-T—are supplied in Tape & Reel packaging, matching the packaging specification of the UP5-680-R. This ensures compatibility with automated assembly processes and standard component handling workflows.

Q: What is the difference between shielded and unshielded configurations?

A: The UP5-680-R, P0250.683NLT, and ASPI-1306T-680M-T are unshielded inductors. The 74459168 is a shielded variant. Shielded inductors reduce electromagnetic field radiation and susceptibility to external interference, beneficial in noise-sensitive applications. Unshielded inductors occupy less board space and typically exhibit lower cost. Selection depends on electromagnetic compatibility requirements of the specific circuit design.

Q: Do all parts meet current RoHS and REACH compliance requirements?

A: The UP5-680-R is RoHS Compliant. The P0250.683NLT, 74459168, and ASPI-1306T-680M-T are ROHS3 Compliant, representing current regulatory standards. The P0250.683NLT, 74459168, and ASPI-1306T-680M-T carry REACH Unaffected status. All parts maintain MSL 1 (Unlimited) moisture sensitivity rating, confirming compatibility with standard storage and handling protocols.

Q: What inventory levels support production planning?

A: Current inventory includes UP5-680-R (1,167 pieces), P0250.683NLT (2,722 pieces), 74459168 (2,000 pieces), and ASPI-1306T-680M-T (1,471 pieces). Combined substitute availability totals 6,193 pieces, supporting extended production runs and supply chain continuity.
