TS5MP646YFPR Equivalent & Substitute Parts

Part Overview

The TS5MP646YFPR is a 10-circuit SPDT IC switch manufactured by Texas Instruments, designed for high-frequency signal routing applications. This device features a 2:1 multiplexer/demultiplexer configuration with 9Ohm on-state resistance and operates across a supply voltage range of 1.65V to 5.5V. The part is classified as "Not For New Designs," indicating it has reached end-of-life status. Identifying equivalent and substitute parts is essential for ongoing system support, maintenance, and design continuity where legacy component replacement is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TS5MP646YFPR is determined by strict alignment of the following core electrical and mechanical parameters:

Critical Substitution Criteria:

• Switch circuit configuration (SPDT)
• Multiplexer/demultiplexer circuit topology (2:1)
• Number of circuits (10)
• On-state resistance compatibility (9Ohm or 10Ohm maximum)
• Supply voltage range overlap (minimum 1.65V to 5.5V coverage)
• Operating temperature range (-40°C to 85°C)
• Package form factor compatibility (36-pin BGA variants)

The TMUX646ZECR qualifies as a direct substitute based on these parameters. Both devices share identical switch circuit topology, channel count, and operating temperature specifications. The TMUX646ZECR maintains on-state resistance within acceptable limits (9Ohm to 10Ohm) and extends supply voltage compatibility to 1.5V minimum, providing broader operational flexibility. Package variants (36-DSBGA versus 36-NFBGA) are mechanically compatible within standard BGA footprint tolerances for this pin count and pitch.

Parameter Comparison

Engineering Selection Recommendations

The TMUX646ZECR is the manufacturer-recommended substitute for the TS5MP646YFPR. Both devices are manufactured by Texas Instruments and maintain functional equivalence across all critical electrical parameters. The TMUX646ZECR carries Active product status, ensuring continued availability and support, whereas the TS5MP646YFPR is designated Not For New Designs.

Key considerations for selection:

The TMUX646ZECR provides enhanced bandwidth performance (6GHz versus 3GHz), which represents a performance improvement over the original part. Supply voltage compatibility is extended to 1.5V minimum, broadening operational range. Moisture sensitivity level differs (MSL 2 versus MSL 1), requiring standard handling procedures during storage and assembly. RoHS compliance status differs; the substitute part lists RoHS status as Not applicable, whereas the original part is ROHS3 compliant. Both parts maintain identical operating temperature specifications and on-state resistance characteristics within acceptable engineering tolerances.

Frequently Asked Questions (FAQ)

Q: Can the TMUX646ZECR directly replace the TS5MP646YFPR in existing designs?

A: Yes. Both devices share identical SPDT 2:1 switch topology, 10-circuit configuration, and on-state resistance specifications. Surface mount BGA packages are mechanically compatible. Electrical performance of the substitute meets or exceeds the original part specifications.

Q: What is the significance of the bandwidth difference (3GHz versus 6GHz)?

A: The TMUX646ZECR provides higher bandwidth capability, which is a performance enhancement. Existing designs operating at or below 3GHz will function without modification. Applications requiring higher frequency performance benefit from the substitute's extended bandwidth.

Q: Are there package compatibility concerns between 36-DSBGA and 36-NFBGA variants?

A: Both packages are 36-pin BGA variants with compatible pitch and footprint specifications for this device class. Standard PCB layout and reflow processes accommodate both package types without design modification.

Q: What is the impact of different Moisture Sensitivity Levels (MSL 1 versus MSL 2)?

A: MSL 1 (unlimited) provides indefinite shelf life without moisture bake-out requirements. MSL 2 (1 year) requires standard moisture control during storage and handling. The substitute part requires standard industry moisture management practices but does not impose additional constraints beyond typical surface mount component handling.

Q: Does the RoHS compliance difference affect substitution suitability?

A: RoHS compliance status is a regulatory and procurement consideration rather than a functional parameter. Selection depends on system-level compliance requirements. Both parts are suitable for applications where RoHS compliance is not mandated.

Q: What supply voltage range should be used for compatibility?

A: The overlapping supply voltage range is 1.65V to 5.5V, which is the safe operating window for both parts. The TMUX646ZECR extends minimum voltage to 1.5V, allowing operation in lower-voltage applications where the original part cannot be used.
