Substitute Part Grouping Explanation

Substitute parts for the SC1608F-100 are qualified based on the following critical parameters:

Inductance Value: 10 µH (within ±20% tolerance)
Current Rating: Minimum 1.1 A
DC Resistance: Maximum 160 mOhm
Shielding Configuration: Unshielded
Mounting Type: Surface Mount
Physical Dimensions: 0.260" L x 0.175" W (6.60mm x 4.45mm) with maximum seated height of 0.115" (2.92mm)
Inductance Test Frequency: 100 kHz
Moisture Sensitivity Level: MSL 1 (Unlimited)

Two substitute parts meet these criteria: the P0770.103NL from Pulse Electronics and the UP0.4C-100-R from Eaton - Electronics Division. Both maintain identical inductance, current rating, DC resistance specifications, and physical form factor compatibility with the SC1608F-100.

Engineering Selection Recommendations

P0770.103NL (Pulse Electronics) is a direct equivalent substitute. It maintains identical electrical specifications (10 µH, 1.1 A, 160 mOhm DCR), physical dimensions, and operating temperature range (-40°C to 130°C). Both the SC1608F-100 and P0770.103NL are ROHS3 compliant with MSL 1 rating. This part is currently active in production with 860 pieces in stock.

UP0.4C-100-R (Eaton - Electronics Division) qualifies as a substitute with minor parameter variations. The current rating is slightly higher at 1.16 A (versus 1.1 A), and DC resistance is marginally lower at 156 mOhm (versus 160 mOhm maximum). The operating temperature range is more restricted (-40°C to 85°C). This part uses a drum core construction with ferrite material and is RoHS compliant. It is available in Tape & Reel packaging with 8681 pieces in stock.

Selection between these substitutes depends on application-specific temperature requirements and packaging format needs.

Frequently Asked Questions (FAQ)

Q: Can the P0770.103NL replace the SC1608F-100 in all applications?

A: Yes. The P0770.103NL maintains identical inductance (10 µH), current rating (1.1 A), DC resistance (160 mOhm maximum), and physical dimensions. Both parts are ROHS3 compliant with MSL 1 rating. The operating temperature range of the P0770.103NL (-40°C to 130°C) exceeds that of the SC1608F-100 (-40°C to 125°C), providing additional thermal margin.

Q: What are the differences between the UP0.4C-100-R and the SC1608F-100?

A: The UP0.4C-100-R has a slightly higher current rating (1.16 A versus 1.1 A) and lower DC resistance (156 mOhm versus 160 mOhm maximum). The operating temperature range is narrower (-40°C to 85°C versus -40°C to 125°C). The UP0.4C-100-R uses drum core construction with ferrite material, while the SC1608F-100 is a standard wirewound design. Physical dimensions and inductance value remain identical.

Q: Are all three parts physically interchangeable?

A: Yes. All three parts share identical physical dimensions (0.260" L x 0.175" W, 6.60mm x 4.45mm) and maximum seated height (0.115", 2.92mm). All are surface mount components with nonstandard package configurations. Direct PCB footprint compatibility is maintained.

Q: Which substitute should be selected for high-temperature applications?

A: The P0770.103NL supports operation up to 130°C, making it suitable for applications requiring higher thermal performance compared to the SC1608F-100 (125°C maximum). The UP0.4C-100-R is limited to 85°C and is not recommended for high-temperature environments.

Q: What is the significance of the MSL 1 rating?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture control requirements. All three parts carry this rating, eliminating moisture-related handling constraints during storage and assembly.

Q: Are there packaging format differences between these substitutes?

A: The SC1608F-100 and P0770.103NL are supplied in standard packaging. The UP0.4C-100-R is available in Tape & Reel (TR) format, which may be preferred for automated assembly processes requiring continuous component feeding.
