Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SD1614T5-B5M is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Rated Voltage: 5V
• Voltage Operating Range: 3 ~ 6V
• Technology: Magnetic
• Driver Circuitry: Transducer, Externally Driven
• Input Type: Zero-Peak Signal
• Mounting Type: Through Hole
• Termination: PC Pins
• Physical Dimensions: 0.630" Dia (16.00mm), Height 0.551" (14.00mm) maximum
• Operating Temperature Range: -40°C ~ 85°C
• RoHS Compliance: ROHS3 Compliant

The SD1614T5-B5ME qualifies as a direct substitute based on full alignment with all mandatory parameters. Both components share identical electrical ratings, mechanical form factors, and environmental compliance specifications. The substitution is valid for applications requiring the same 5V magnetic buzzer transducer functionality.

Parameter Comparison

Engineering Selection Recommendations

Both the SD1614T5-B5M and SD1614T5-B5ME are Last Time Buy components from TDK Corporation, indicating end-of-life status for both variants. Selection between these parts should be based on current inventory availability and packaging requirements.

The SD1614T5-B5M is available in standard packaging with 1,000,300 pieces in stock. The SD1614T5-B5ME is supplied in bulk packaging with 1,920 pieces in stock. Both components maintain ROHS3 compliance and identical electrical and mechanical specifications, ensuring functional interchangeability in circuit designs.

For applications requiring long-term component availability beyond current stock levels, alternative sourcing strategies should be evaluated, as both parts carry Last Time Buy status.

Frequently Asked Questions (FAQ)

Q: Can SD1614T5-B5ME replace SD1614T5-B5M in existing designs?

A: Yes. Both components share identical electrical ratings (5V, 80mA), frequency response (2.048kHz), acoustic output (85dB @ 5V, 10cm), mechanical dimensions (16mm diameter, 14mm height), mounting configuration (through-hole PC pins), and operating temperature range (-40°C to 85°C). No circuit modifications are required.

Q: What is the difference between these two part numbers?

A: The primary difference is packaging format. SD1614T5-B5M uses standard packaging, while SD1614T5-B5ME uses bulk packaging. Both components are functionally identical magnetic buzzer transducers from the same TDK SD series.

Q: Are there any compliance differences between these parts?

A: No. Both components are ROHS3 compliant and carry identical environmental ratings. The SD1614T5-B5M has MSL 1 (Unlimited), while the SD1614T5-B5ME lists MSL as Not Applicable, reflecting packaging differences only.

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

A: Last Time Buy indicates that both the SD1614T5-B5M and SD1614T5-B5ME are discontinued products with no future production planned. Current stock represents the final available inventory from the manufacturer.

Q: Are these components suitable for 3V or 6V operation?

A: Yes. Both components operate across the 3V to 6V range, though the rated specifications are based on 5V operation. Operation outside the rated voltage will affect sound pressure level and current consumption.
