Key Parameters

Substitute Part Grouping Explanation

Substitution for the SC16C752IB48,157 is determined by the following critical parameters:

Core Functional Requirements:

• Dual UART channel configuration (DUART)
• 64-byte FIFO buffer capacity
• Modem control support
• Auto flow control capability
• False start bit detection

Electrical Compatibility:

• Supply voltage range compatibility
• Maximum data rate capability
• Protocol support (RS232 minimum)

Physical Compatibility:

• 48-pin package format (LQFP or TQFP variants acceptable)
• Surface mount mounting type
• 7x7mm package dimensions

Compliance Requirements:

• RoHS3 compliance
• REACH unaffected status

Substitute parts are grouped into two categories: parametric equivalents from NXP (same manufacturer, identical electrical specifications) and manufacturer-recommended alternatives from MaxLinear (enhanced specifications, active product status).

Parameter Comparison

Engineering Selection Recommendations

NXP Parametric Equivalents (SC16C752BIB48,151 and SC16C752BIB48,157): These parts maintain identical electrical and functional specifications to the SC16C752IB48,157. Both are obsolete products from the same manufacturer. Selection between these NXP variants is based on packaging format (Tray) and inventory availability. These are direct functional replacements with no design modifications required.

MaxLinear Active Alternatives: The XR16L2750 series (XR16L2750IM-F, XR16L2750IMTR-F) provides enhanced data rate capability (6.25Mbps) and expanded protocol support (RS232, RS485) while maintaining the 64-byte FIFO and dual-channel architecture. These parts are in active production status and RoHS3 compliant.

The XR16M752 and XR68M752 series represent the highest performance tier, supporting 16Mbps data rates and triple protocol support (RS232, RS422, RS485). These parts operate at lower voltage ranges (1.62V ~ 3.63V) and are suitable for modern low-power applications. Both series are active products with full RoHS compliance.

Packaging Considerations: The original SC16C752IB48,157 uses 48-LQFP packaging. MaxLinear substitutes use 48-TQFP packaging. Both package types are 48-pin, 7x7mm surface mount formats with compatible pinouts for UART functionality. PCB layout modifications may be required due to subtle differences in pin geometry between LQFP and TQFP variants.

Frequently Asked Questions (FAQ)

Q: Can I directly replace SC16C752IB48,157 with SC16C752BIB48,151? A: Yes. Both parts are NXP products with identical electrical specifications, channel count, FIFO capacity, and voltage supply ranges. The primary difference is packaging format (Tray vs. original packaging). No design changes are required.

Q: What is the key difference between NXP and MaxLinear substitutes? A: NXP substitutes (SC16C752BIB48 variants) are parametric equivalents with identical 5Mbps data rates and obsolete status. MaxLinear alternatives are active products with enhanced data rates (6.25Mbps for XR16L2750 series; 16Mbps for XR16M752/XR68M752 series) and expanded protocol support. MaxLinear parts are recommended for new designs requiring long-term availability.

Q: Are LQFP and TQFP packages interchangeable? A: Both are 48-pin, 7x7mm surface mount packages with compatible pinouts for UART applications. However, subtle differences in pin geometry exist between LQFP and TQFP variants. PCB footprint verification and potential layout adjustments are necessary before substitution.

Q: Which MaxLinear part should I select for new designs? A: Selection depends on application requirements. The XR16L2750 series is suitable for applications requiring RS232/RS485 protocols at up to 6.25Mbps. The XR16M752 and XR68M752 series are recommended for applications requiring higher data rates (16Mbps) and triple protocol support (RS232, RS422, RS485) with lower voltage operation.

Q: What is the difference between XR16M752IM48-F and XR16M752IM48TR-F? A: Both parts are electrically identical. The primary difference is packaging format: XR16M752IM48-F is supplied in Tray format, while XR16M752IM48TR-F is supplied in Tape & Reel (TR) format. Selection is based on procurement and assembly requirements.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed substitute parts maintain RoHS3 compliance and REACH unaffected status, consistent with the original SC16C752IB48,157 specifications.

Q: What voltage range compatibility should I verify? A: The original part operates at 2.5V, 3.3V, and 5V. NXP substitutes maintain this range. MaxLinear XR16L2750 series supports 2.25V ~ 5.5V (broader range). MaxLinear XR16M752 and XR68M752 series operate at 1.62V ~ 3.63V (lower voltage range). Verify your application's supply voltage compatibility before selection.
