Substitute Part Grouping Explanation

Substitute parts for the UP1B-150 are grouped based on the following critical electrical and mechanical parameters that determine functional equivalence:

Primary Matching Criteria:

• Inductance value: 15 µH (±20% tolerance allows 12 µH to 18 µH range)
• Current rating: Minimum 1.2 A continuous
• DC resistance: Maximum 174.7 mOhm
• Shielding configuration: Unshielded
• Mounting type: Surface Mount
• Operating temperature range: Minimum -40°C to 85°C coverage
• Physical footprint compatibility: 0.350" L x 0.240" W nominal dimensions

Substitution Logic: Direct substitutes maintain identical inductance values and electrical specifications. Similar substitutes may vary in inductance within the tolerance band, current saturation ratings, or DC resistance characteristics while maintaining functional compatibility within the specified operating parameters. All substitute parts must support surface mount assembly and operate within the required temperature range.

Engineering Selection Recommendations

UP1B-150-R (Direct Substitute - Eaton - Electronics Division)

The UP1B-150-R is the direct equivalent of the UP1B-150, maintaining identical electrical specifications including 15 µH inductance, 1.2 A current rating, and 174.7 mOhm maximum DC resistance. The primary distinction is product status: UP1B-150-R is active while UP1B-150 is obsolete. UP1B-150-R is ROHS3 compliant and available in Tape & Reel packaging, providing superior supply chain continuity and manufacturing process compatibility. This part is the preferred replacement for new designs and production continuity.

PA0390.153NL (Similar Substitute - Pulse Electronics)

The PA0390.153NL from Pulse Electronics provides functional substitution with 16 µH inductance, which falls within the ±20% tolerance band of the 15 µH specification. Electrical parameters including 1.2 A current rating and 174.7 mOhm maximum DC resistance match the original part. The operating temperature range extends to 130°C, exceeding the UP1B-150 specification. Physical dimensions remain compatible at 0.350" L x 0.240" W. This part is ROHS3 compliant and active in production. Selection of this part requires confirmation that the 16 µH inductance value is acceptable within circuit design tolerances.

SDR0805-150ML (Similar Substitute - Bourns Inc.)

The SDR0805-150ML from Bourns Inc. maintains the exact 15 µH inductance value with ±20% tolerance. This part offers enhanced electrical performance with 1.8 A current rating and 2.7 A saturation current, compared to 1.2 A and 1.5 A respectively on the UP1B-150. DC resistance is reduced to 90 mOhm maximum, providing lower power dissipation. Operating temperature range extends to 125°C. Physical footprint differs slightly with 0.307" L x 0.307" W dimensions and 0.209" maximum height. This part is ROHS3 compliant and available in Tape & Reel packaging. PCB layout verification is required to confirm dimensional compatibility.

Frequently Asked Questions (FAQ)

Q: Can UP1B-150-R be used as a direct replacement for UP1B-150?

A: Yes. UP1B-150-R is electrically and mechanically identical to UP1B-150, with matching inductance (15 µH), current rating (1.2 A), DC resistance (174.7 mOhm), and physical dimensions (0.350" L x 0.240" W). The primary difference is product status and compliance certification. UP1B-150-R is active and ROHS3 compliant, making it the recommended replacement.

Q: Is PA0390.153NL compatible with circuits designed for UP1B-150?

A: PA0390.153NL is compatible when the 16 µH inductance value is acceptable within circuit design tolerances. The ±20% tolerance specification allows inductance values from 12 µH to 18 µH, encompassing both the 15 µH original and 16 µH substitute. All other electrical parameters including current rating and DC resistance match the original specification. Circuit performance validation is required to confirm functional equivalence.

Q: What are the advantages of SDR0805-150ML over UP1B-150?

A: SDR0805-150ML provides enhanced performance characteristics including higher current rating (1.8 A versus 1.2 A), higher saturation current (2.7 A versus 1.5 A), and lower DC resistance (90 mOhm versus 174.7 mOhm). These characteristics result in reduced power dissipation and improved current handling capability. Operating temperature range extends to 125°C. Physical dimensions differ slightly, requiring PCB layout verification.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. UP1B-150-R, PA0390.153NL, and SDR0805-150ML are all ROHS3 compliant. The original UP1B-150 is RoHS non-compliant. Compliance certification is an important consideration for new designs and manufacturing processes subject to environmental regulations.

Q: What packaging options are available for these parts?

A: UP1B-150 is supplied in bulk packaging. UP1B-150-R and SDR0805-150ML are available in Tape & Reel (TR) packaging, which is standard for automated assembly processes. PA0390.153NL is supplied in bulk packaging. Packaging selection depends on production volume and assembly equipment requirements.

Q: Do the substitute parts have identical physical dimensions?

A: UP1B-150-R maintains identical dimensions (0.350" L x 0.240" W, 0.197" height). PA0390.153NL has nearly identical dimensions (0.350" L x 0.240" W, 0.200" height). SDR0805-150ML has different dimensions (0.307" L x 0.307" W, 0.209" height). PCB layout verification is required when substituting SDR0805-150ML to confirm footprint compatibility.

Q: What is the inductance tolerance for all parts?

A: All parts including UP1B-150, UP1B-150-R, PA0390.153NL, and SDR0805-150ML have ±20% inductance tolerance. This tolerance band allows for manufacturing variation and must be considered in circuit design calculations.

Q: Can SDR0805-150ML be used in high-temperature applications?

A: SDR0805-150ML operates to 125°C, which exceeds the UP1B-150 specification of 85°C. PA0390.153NL extends to 130°C. Selection for high-temperature applications requires confirmation that the substitute part's temperature rating meets or exceeds the application requirement.
