B39171B3882Z710

Overview

The B39171B3882Z710 is a Surface Acoustic Wave (SAW) filter manufactured by Qualcomm, designed for RF front-end applications. It operates at a center frequency of 168.96MHz with a bandwidth of 3.84MHz and an insertion loss of 13dB. The component utilizes a surface mount package measuring 5.00mm x 3.50mm with a maximum height of 1.10mm. This device is part of the B39171 series and is currently classified as obsolete.

Feature Summary

• Utilizes Surface Acoustic Wave (SAW) technology for signal filtering
• Designed for general RF front-end applications
• Surface mount construction for automated assembly

Applications

• General RF filtering in communication systems

Procurement Notes

This component is officially listed as obsolete by the manufacturer. Procurement should focus on verifying the authenticity of remaining stock from authorized distributors or secondary market suppliers. Ensure that any available units match the original specifications and packaging requirements. Due to its discontinued status, long-term supply availability cannot be guaranteed, and alternative solutions may need to be evaluated for new designs.

Selection Notes

Engineers selecting this part must account for its obsolete status when planning production lifecycles. The specific electrical parameters, including the 168.96MHz center frequency and 13dB insertion loss, define its operational limits. Designers should verify compatibility with existing circuit layouts due to the 4-SMD package dimensions. Replacement strategies should be prioritized given the lack of future manufacturing support.

Part Context

The B39171B3882Z710 belongs to Qualcomm's broader portfolio of RF front-end filters, which includes technologies like ultraBAW and TC-SAW. While the manufacturer promotes advanced solutions for 5G and IoT, this specific SAW model serves legacy or specialized low-frequency applications. It represents a discrete filtering solution within the company's historical product line, distinct from their integrated modem-RF platforms.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Given the obsolete status, engineers must evaluate functional equivalents based on matching center frequency (168.96MHz), bandwidth, and package constraints. Cross-referencing with current Qualcomm RFFE catalogs or third-party SAW filter manufacturers is recommended.
