Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 450-0162R is determined by the following critical parameters:

RF Capability Match: Both the main part and substitute must support Bluetooth and WiFi protocols within the 2.4GHz ISM band (2.402GHz ~ 2.48GHz).

Mounting and Package Compatibility: Surface mount technology with module-level packaging is required to maintain PCB integration compatibility.

Serial Interface Compatibility: The substitute must provide at least one common serial interface (UART is the baseline interface present in both parts).

Environmental and Compliance Alignment: Operating temperature range and RoHS/REACH compliance status must be suitable for the target application environment.

Antenna Configuration: Substitutes may differ in antenna implementation (integrated versus external connector) provided the RF performance characteristics remain within acceptable operational parameters for the application.

The ST60-SIPT qualifies as a substitute based on shared RF family (Bluetooth, WiFi), 2.4GHz operation, surface mount configuration, UART interface availability, and equivalent environmental ratings.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using 450-0162R: The ST60-SIPT represents the manufacturer-recommended substitute path. The ST60-SIPT maintains active product status, ensuring continued availability and technical support from Laird Connectivity Inc., whereas the 450-0162R is designated Last Time Buy.

Compliance Considerations: Both parts meet RoHS requirements. The ST60-SIPT carries ROHS3 compliance and REACH Unaffected status, providing regulatory alignment for current and future market requirements.

Temperature Range Limitation: The ST60-SIPT operating temperature range (-30°C ~ 85°C) is narrower than the 450-0162R (-40°C ~ 85°C). Applications requiring operation below -30°C must retain the 450-0162R or identify alternative solutions.

Antenna Architecture Change: The 450-0162R features integrated chip antenna, while the ST60-SIPT requires external antenna via U.FL connector. PCB layout modifications are necessary to accommodate external antenna placement and impedance matching.

Interface Adaptation: The 450-0162R provides PCM and SDIO interfaces in addition to UART. The ST60-SIPT offers USB in addition to UART. Applications dependent on PCM or SDIO protocols cannot substitute to ST60-SIPT without firmware or hardware redesign.

Frequently Asked Questions (FAQ)

Q: Can ST60-SIPT directly replace 450-0162R on existing PCBs?

A: Direct PCB replacement is not possible. The ST60-SIPT requires external antenna connection via U.FL connector, whereas the 450-0162R has integrated antenna. PCB layout modification is required, including antenna placement and RF trace impedance matching.

Q: What are the key differences in serial interface capability?

A: The 450-0162R provides PCM, SDIO, and UART interfaces. The ST60-SIPT provides UART and USB interfaces. Applications using PCM or SDIO protocols cannot migrate to ST60-SIPT without redesign. UART is the common interface available on both parts.

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

A: No. The ST60-SIPT minimum operating temperature is -30°C. Applications requiring -40°C operation must retain the 450-0162R or identify alternative components with extended temperature range.

Q: What is the significance of Last Time Buy status for 450-0162R?

A: Last Time Buy indicates the manufacturer will no longer accept new orders after a specified cutoff date. Existing inventory (869 Pcs noted as in stock) represents the final available supply. New designs should transition to ST60-SIPT or equivalent active-status alternatives.

Q: Are there differences in RF performance between the two modules?

A: The 450-0162R specifies 433.3Mbps data rate, 16dBm output power, and -93dBm sensitivity. The ST60-SIPT does not provide these specifications in the available data. Performance validation through testing is required for applications with specific RF performance requirements.

Q: What is the impact of antenna type change on system design?

A: The 450-0162R integrated antenna eliminates external antenna design complexity but provides fixed radiation pattern. The ST60-SIPT U.FL connector allows antenna selection optimization for specific application environments but requires antenna procurement, impedance matching, and placement validation.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both parts are RoHS compliant. The ST60-SIPT additionally carries ROHS3 compliance and REACH Unaffected status, providing alignment with current and anticipated regulatory requirements.
