Key Parameters

Substitute Part Grouping Explanation

Substitution of the 450-0162C is determined by the following critical parameters:

RF Compatibility Parameters:

• RF Family/Standard: Bluetooth and WiFi capability
• Frequency Range: Operation within 2.4GHz ISM band
• Protocol Support: 802.11 and Bluetooth standards

Electrical Parameters:

• Voltage Supply Range: 3.2V to 3.6V operation
• Serial Interfaces: PCM, SDIO, UART support for host communication
• Mounting Type: Surface Mount configuration

Physical Parameters:

• Package Type: Module form factor
• Antenna Configuration: Integrated or external antenna support
• MSL Rating: 4 (72 Hours) moisture sensitivity level

The substitute part ST60-SIPT shares the core RF family (Bluetooth, WiFi), operates in the 2.4GHz band, maintains surface mount configuration, and carries equivalent MSL and RoHS compliance ratings. However, differences exist in specific protocol support, data rate specifications, and antenna implementation that must be evaluated for design compatibility.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The 450-0162C carries Last Time Buy status, indicating end-of-life production. The ST60-SIPT maintains Active product status with current manufacturing availability, making it the primary candidate for new designs and long-term supply continuity.

Compliance and Certification: Both parts maintain equivalent MSL ratings (4, 72 Hours) and REACH unaffected status. The ST60-SIPT carries ROHS3 compliance, representing current regulatory alignment. Both parts share identical HTSUS classification (8517.62.0090), confirming tariff equivalence.

Interface and Antenna Differences: The 450-0162C integrates on-chip antenna capability with PCM, SDIO, and UART interfaces. The ST60-SIPT requires external antenna via U.FL connector and provides UART and USB interfaces. Design integration must account for antenna implementation differences and serial interface availability in the host system.

Temperature Range: The 450-0162C supports -40°C to 85°C operation, while ST60-SIPT supports -30°C to 85°C. Applications requiring sub-zero operation below -30°C cannot use ST60-SIPT as a direct substitute.

RF Performance Parameters: Specific power output, sensitivity, and data rate values are not provided for ST60-SIPT. Designs dependent on the 450-0162C's 16dBm output, -93dBm sensitivity, or 433.3Mbps data rate require verification against ST60-SIPT specifications before implementation.

Frequently Asked Questions (FAQ)

Q: Can ST60-SIPT directly replace 450-0162C in existing PCB designs?

A: Direct PCB replacement is not possible due to antenna implementation differences. The 450-0162C uses integrated chip antenna, while ST60-SIPT requires external antenna connection via U.FL connector. PCB layout modifications and antenna design are required.

Q: What are the serial interface compatibility considerations?

A: The 450-0162C provides PCM, SDIO, and UART interfaces. The ST60-SIPT provides UART and USB interfaces. Designs using PCM or SDIO cannot use ST60-SIPT without host system redesign. UART-based designs may be compatible if baud rate and protocol requirements align.

Q: Is ST60-SIPT suitable for applications requiring -40°C operation?

A: No. The ST60-SIPT operating temperature range is -30°C to 85°C. Applications requiring operation below -30°C must retain the 450-0162C or identify alternative parts with extended low-temperature specifications.

Q: How do the RF performance specifications compare?

A: The 450-0162C specifies 16dBm output power, -93dBm sensitivity, and 433.3Mbps data rate. ST60-SIPT specifications for these parameters are not provided in available documentation. Performance verification is required before substitution in designs with specific RF performance requirements.

Q: What packaging differences exist between these parts?

A: The 450-0162C is supplied in Strip packaging (60-SMD Module). The ST60-SIPT is supplied in Tape & Reel (TR) packaging. Both use surface mount configuration. Packaging differences affect handling, storage, and assembly processes but do not impact electrical compatibility.

Q: Are both parts RoHS compliant?

A: Yes. The 450-0162C is RoHS Compliant. The ST60-SIPT is ROHS3 Compliant. Both meet current RoHS requirements. ROHS3 represents the current regulatory standard.

Q: What is the moisture sensitivity level for both parts?

A: Both parts carry MSL rating 4 (72 Hours), indicating identical moisture sensitivity and requiring equivalent storage and handling procedures.
