Key Parameters

Substitute Part Grouping Explanation

Substitution of the SC18IM700IPW/S8HP is determined by the following critical parameters:

Protocol & Function Compatibility: Both the main part and substitute must support I2C protocol with Controller function and UART interface capability.

Package Compatibility: The 16-TSSOP package form factor must be identical to ensure PCB layout compatibility without redesign.

Voltage Supply Range: The substitute must operate within or encompass the supply voltage range of the original part (2.4V ~ 3.6V).

Operating Temperature Range: The substitute must support the minimum operating temperature of -40°C; upper temperature range may exceed the original specification.

Compliance & Certification: RoHS3 compliance and MSL rating must be maintained for manufacturing and environmental standards adherence.

The SC18IM704PWJ qualifies as a direct substitute based on these parameters: identical protocol, function, interface, and package; compatible voltage and temperature ranges; and equivalent compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The SC18IM704PWJ is the qualified substitute for the SC18IM700IPW/S8HP based on the following engineering criteria:

Product Status: The SC18IM704PWJ maintains Active product status, ensuring continued availability, manufacturing support, and technical documentation from NXP USA Inc. The original SC18IM700IPW/S8HP is Obsolete, limiting future procurement options.

Compliance & Certification: Both parts maintain ROHS3 compliance and identical MSL ratings, satisfying environmental and manufacturing standards without additional qualification.

Electrical Performance: The SC18IM704PWJ operates across a wider supply voltage range (1.71V ~ 3.6V) and extended temperature range (-40°C ~ 105°C), providing enhanced operational flexibility. Supply current is reduced to 4mA compared to 9mA, offering improved power efficiency.

Package & Interface Compatibility: Identical 16-TSSOP packaging and I2C/UART protocol support ensure direct PCB-level compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the SC18IM704PWJ be used as a direct replacement for the SC18IM700IPW/S8HP?

A: Yes. Both parts share identical protocol (I2C), function (Controller), interface (UART), and package (16-TSSOP). The SC18IM704PWJ operates within the voltage and temperature ranges required by the original part and is currently in active production.

Q: What are the key differences between these parts?

A: The SC18IM704PWJ features a wider supply voltage range (1.71V ~ 3.6V versus 2.4V ~ 3.6V), lower supply current (4mA versus 9mA), and extended operating temperature range (-40°C ~ 105°C versus -40°C ~ 85°C). Both maintain identical RoHS3 compliance and MSL ratings.

Q: Does the lower supply current of the SC18IM704PWJ affect functionality?

A: No. Lower supply current indicates improved power efficiency and does not impact functional capability. The part maintains identical protocol support and controller function.

Q: Are there any package or pinout differences?

A: No. Both parts use the 16-TSSOP package with identical form factor (0.173", 4.40mm Width), ensuring direct PCB compatibility without redesign.

Q: Why is the SC18IM700IPW/S8HP classified as Obsolete?

A: The SC18IM700IPW/S8HP has reached end-of-life status. The SC18IM704PWJ is the active equivalent from NXP USA Inc., recommended for new designs and ongoing system support.

Q: Are compliance certifications maintained with the substitute?

A: Yes. The SC18IM704PWJ maintains ROHS3 compliance, MSL Level 1 rating, and REACH Unaffected status, identical to the original part.
