• Output configuration: Positive, Fixed

Two substitute options are available: one direct equivalent with identical specifications and packaging format, and one parametrically equivalent alternative with improved performance characteristics in specific parameters.

Parameter Comparison

Engineering Selection Recommendations

S-1112B48PI-L7HTFU is the direct equivalent substitute. This part maintains identical electrical specifications and packaging format while offering the advantage of active product status. It is suitable for direct replacement in applications currently using the obsolete S-1112B48PI-L7HTFG. Both parts share the same series designation, package type (SNT-6A), and performance characteristics. This option provides the most straightforward migration path with no design modifications required.

S-1167B48-I6T2U is a parametrically equivalent alternative from an improved product series. While maintaining the same output voltage, current rating, input voltage range, and package configuration, this part demonstrates enhanced performance in specific parameters: reduced dropout voltage (0.21V vs. 0.26V @ 100mA), lower quiescent current (900nA vs. 1µA), and significantly reduced supply current (16µA vs. 90µA). The PSRR specification is lower (65dB vs. 80dB @ 1kHz). This option is suitable for applications where lower power consumption and reduced dropout voltage provide system-level benefits. Both substitute options maintain full compliance with ROHS3, REACH, and MSL requirements.

Frequently Asked Questions (FAQ)

Q: Can S-1112B48PI-L7HTFU be used as a direct replacement for S-1112B48PI-L7HTFG?

A: Yes. S-1112B48PI-L7HTFU is a direct equivalent with identical electrical specifications, output voltage (4.8V fixed), output current (150mA), input voltage range (6.5V maximum), dropout voltage (0.26V @ 100mA), and package type (6-SMD, Flat Leads, SNT-6A). The primary difference is product status: S-1112B48PI-L7HTFU is active while the original is obsolete. No circuit modifications are required.

Q: What are the differences between S-1112B48PI-L7HTFU and S-1167B48-I6T2U?

A: Both parts deliver identical output voltage (4.8V), output current (150mA), and use the same package (SNT-6A). The S-1167B48-I6T2U offers improved performance in dropout voltage (0.21V vs. 0.26V @ 100mA), quiescent current (900nA vs. 1µA), and supply current (16µA vs. 90µA). The S-1167B48-I6T2U has lower PSRR (65dB vs. 80dB @ 1kHz). Both are active products with identical compliance certifications.

Q: Are the packaging and mounting configurations identical across all three parts?

A: Yes. All three parts use the same package type: 6-SMD, Flat Leads with supplier device package designation SNT-6A. All are surface mount components with identical mechanical footprints. The only packaging difference is that S-1112B48PI-L7HTFG is supplied in standard packaging while S-1112B48PI-L7HTFU and S-1167B48-I6T2U are supplied in Tape & Reel format.

Q: Which substitute should be selected for new designs?

A: For new designs, either active product option is suitable. S-1112B48PI-L7HTFU maintains identical specifications to the original design. S-1167B48-I6T2U is recommended if the application benefits from lower power consumption or reduced dropout voltage. Both parts are ROHS3 compliant, REACH unaffected, and have unlimited moisture sensitivity rating (MSL 1).

Q: Are there any temperature or compliance differences between the substitutes?

A: No. All three parts operate across the identical temperature range (-40°C ~ 85°C), maintain ROHS3 compliance, are REACH unaffected, and have MSL rating of 1 (Unlimited). Compliance and environmental specifications are equivalent across all options.
