RF3417E Equivalent & Substitute Parts

Part Overview

The RF3417E is a 315MHz Surface Acoustic Wave (SAW) filter manufactured by Murata Electronics, designed for remote control applications. This component features a 600kHz bandwidth with 1.8dB insertion loss in a 6-SMD, no-lead surface mount package. The part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications requiring this specific frequency and performance profile.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RF3417E is determined by the following critical parameters:

• Center Frequency: Must be 315MHz to maintain RF circuit tuning and system compatibility
• Package Type & Dimensions: Must be 6-SMD, no-lead with 3.00mm x 3.00mm footprint for PCB layout compatibility
• Mounting Type: Must be surface mount to match assembly process requirements
• Application Category: Remote control frequency band filters

The B39321B3731H110 qualifies as a substitute based on matching center frequency, package type, dimensions, and mounting configuration. Variations in bandwidth and insertion loss represent acceptable performance trade-offs within the remote control filter category, provided the substitute meets the electrical requirements of the target application circuit.

Parameter Comparison

Engineering Selection Recommendations

The B39321B3731H110 is an active production substitute for the obsolete RF3417E. Both components meet ROHS3 compliance requirements and share identical center frequency and package footprint specifications. The substitute exhibits a narrower bandwidth (120kHz vs. 600kHz) and slightly higher insertion loss (2.4dB vs. 1.8dB), which may impact selectivity and signal attenuation characteristics in the target circuit. The B39321B3731H110 includes AEC-Q200 automotive qualification and is available in standard tape & reel production packaging, supporting high-volume manufacturing workflows. The substitute's reduced height profile (1.00mm vs. 1.38mm) provides additional PCB assembly clearance benefits.

Frequently Asked Questions (FAQ)

Q: Can the B39321B3731H110 be used as a direct replacement for RF3417E in existing designs?

A: Physical and electrical compatibility is confirmed for the 315MHz center frequency and 6-SMD package footprint. However, the narrower bandwidth and increased insertion loss of the substitute may require circuit-level validation to confirm performance within system specifications.

Q: What is the significance of the bandwidth difference between these parts?

A: The RF3417E provides 600kHz bandwidth while the B39321B3731H110 provides 120kHz bandwidth. Narrower bandwidth offers improved selectivity and rejection of adjacent frequency interference, but may reduce the frequency tuning range tolerance in the application circuit.

Q: Are there packaging considerations for substitution?

A: The RF3417E is supplied in bulk packaging, while the B39321B3731H110 is supplied in tape & reel format. Both maintain identical 3.00mm x 3.00mm footprints and surface mount compatibility. The substitute's lower profile (1.00mm vs. 1.38mm) may provide additional assembly clearance.

Q: What compliance certifications apply to the substitute part?

A: The B39321B3731H110 meets ROHS3 compliance, AEC-Q200 automotive qualification, and REACH unaffected status. The original RF3417E meets ROHS3 compliance with MSL 1 rating.

Q: How do moisture sensitivity levels differ between these parts?

A: The RF3417E carries MSL 1 (unlimited moisture exposure tolerance), while the B39321B3731H110 carries MSL 3 (168-hour moisture exposure limit). This difference may impact storage, handling, and assembly process requirements.
