Key Parameters

Substitute Part Grouping Explanation

The substitute part 450-0103R is classified as a direct equivalent based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

Critical Matching Parameters:

• Bluetooth v4.0 protocol compliance
• 2.4GHz frequency band operation
• CC2541 integrated circuit
• 256kB Flash / 8kB RAM memory configuration
• 2V ~ 3.6V supply voltage range
• I2C and SPI serial interface support
• Integrated trace antenna configuration
• Surface mount module package type
• Operating temperature range -40°C ~ 85°C
• RoHS compliance status

The primary difference between 450-0103C and 450-0103R is packaging format: 450-0103C is supplied in Strip packaging, while 450-0103R is supplied in Cut Tape (CT) packaging. Both parts are from the TiWi-uB1 series and share identical electrical performance specifications.

Parameter Comparison

Engineering Selection Recommendations

Both 450-0103C and 450-0103R are functionally equivalent Bluetooth v4.0 transceiver modules from the Laird Connectivity TiWi-uB1 series. Selection between these parts should be based on packaging and procurement requirements:

450-0103C (Strip Packaging): Select when strip packaging format aligns with assembly line requirements or when existing inventory management systems are configured for strip format delivery.

450-0103R (Cut Tape Packaging): Select when cut tape format is required for automated pick-and-place assembly equipment or when procurement volume and logistics favor cut tape distribution.

Both parts carry Last Time Buy status and are RoHS compliant. Inventory availability differs: 450-0103C has 1171 pieces in stock, while 450-0103R has 2679 pieces in stock. For long-term design support, procurement planning should account for Last Time Buy designation and available inventory levels.

Frequently Asked Questions (FAQ)

Q: Can 450-0103R be used as a direct replacement for 450-0103C in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Strip versus Cut Tape). No circuit design changes are required for substitution.

Q: What is the difference between Strip and Cut Tape packaging?

A: Strip packaging delivers components on a continuous carrier strip, while Cut Tape (CT) packaging provides components on individual tape segments. Cut Tape is typically used for automated assembly equipment, while Strip may be used for manual assembly or different handling processes.

Q: Are there any compliance or certification differences between these parts?

A: No. Both 450-0103C and 450-0103R share identical RoHS compliance status, MSL rating (4, 72 Hours), ECCN classification (EAR99), and HTSUS code (8517.62.0090).

Q: What does Last Time Buy status mean for these parts?

A: Last Time Buy indicates that Laird Connectivity Inc. will no longer manufacture these parts after current inventory is depleted. Procurement planning should account for this status when selecting between available inventory quantities.

Q: Do both parts use the same CC2541 integrated circuit?

A: Yes. Both 450-0103C and 450-0103R utilize the CC2541 IC with identical memory configuration (256kB Flash, 8kB RAM) and identical RF performance specifications.

Q: Are the antenna configurations identical?

A: Yes. Both parts feature integrated trace antenna configuration, providing identical RF performance and PCB layout requirements.

Q: What is the moisture sensitivity level for these modules?

A: Both parts have MSL rating 4 with 72-hour floor life. This indicates moderate moisture sensitivity requiring controlled storage and handling conditions.
