UP0.4SC-152-R Equivalent & Substitute Parts

Part Overview

The UP0.4SC-152-R is a 1.5 mH shielded wirewound inductor manufactured by Eaton - Electronics Division, designed for surface mount applications requiring fixed inductance in compact form factors. This component operates across an industrial temperature range of -40°C to 125°C with a maximum DC resistance of 4.2Ohm and supports a 120 mA current rating. The part maintains Active product status with RoHS compliance and unlimited moisture sensitivity rating (MSL 1). Substitute components are identified when electrical specifications, mechanical dimensions, and environmental ratings align within acceptable tolerances for direct circuit board replacement.

Substitute Part Grouping Explanation

Substitution eligibility for the UP0.4SC-152-R is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

Inductance value: 1.5 mH with ±20% tolerance
Current rating: 120 mA minimum
DC resistance: 4.2Ohm maximum
Q factor: 50 @ 100kHz
Self resonant frequency: 2 MHz
Shielding: Shielded construction required
Mounting: Surface mount configuration
Package dimensions: Nonstandard form factor within specified length, width, and height tolerances

The SRR6603-152ML from Bourns Inc. qualifies as a substitute component because it matches all critical electrical specifications and maintains compatible physical dimensions within the nonstandard package category. Both components are Active products with appropriate compliance certifications.

Engineering Selection Recommendations

UP0.4SC-152-R (Eaton - Electronics Division)

Primary selection when Eaton component availability and supply chain continuity are prioritized. Active product status with RoHS compliance and unlimited MSL rating support long-term production requirements. Current inventory of 920 pieces supports immediate procurement needs.

SRR6603-152ML (Bourns Inc.)

Direct substitute when Bourns component sourcing is preferred or Eaton availability is constrained. Identical electrical performance across all critical parameters. Extended operating temperature range (-55°C to 125°C) provides additional thermal margin for applications requiring lower temperature operation. Higher inventory availability (2200 pieces) supports volume production schedules. ROHS3 compliance and REACH Unaffected status meet current regulatory requirements.

Both components are suitable for direct substitution in surface mount applications requiring 1.5 mH inductance at 120 mA current rating with shielded construction.

Frequently Asked Questions (FAQ)

Q: Can SRR6603-152ML replace UP0.4SC-152-R in existing circuit designs?

A: Yes. Both components match across all critical electrical parameters: 1.5 mH inductance, ±20% tolerance, 120 mA current rating, 4.2Ohm maximum DC resistance, 50 Q factor at 100kHz, and 2 MHz self resonant frequency. Physical dimensions are compatible within nonstandard package tolerances.

Q: What are the dimensional differences between these components?

A: Length is identical at 6.60 mm. Width differs by 0.05 mm (UP0.4SC-152-R: 4.45 mm; SRR6603-152ML: 4.40 mm). Height differs by 0.08 mm (UP0.4SC-152-R: 2.92 mm maximum; SRR6603-152ML: 3.00 mm maximum). These variations are within acceptable tolerances for surface mount placement and do not affect circuit board layout compatibility.

Q: Are there temperature rating differences?

A: The UP0.4SC-152-R operates from -40°C to 125°C. The SRR6603-152ML extends the lower operating limit to -55°C while maintaining the same 125°C upper limit. Both ratings support standard industrial applications. Selection depends on specific application temperature requirements.

Q: Do both components meet current compliance standards?

A: Yes. UP0.4SC-152-R is RoHS Compliant. SRR6603-152ML is ROHS3 Compliant and REACH Unaffected. Both components carry MSL 1 (Unlimited) moisture sensitivity ratings and are suitable for production environments without special handling requirements.

Q: What is the saturation current specification?

A: The UP0.4SC-152-R saturation current is not specified in available documentation. The SRR6603-152ML specifies 35 mA saturation current. For applications where saturation current is a critical design parameter, verify this specification against circuit requirements before substitution.

Q: Are both components available in tape and reel packaging?

A: Yes. Both UP0.4SC-152-R and SRR6603-152ML are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.
