Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TC-16.000MBD-T is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 16 MHz
• Output Type: CMOS
• Supply Voltage: 3.3V
• Function: Enable/Disable
• Frequency Stability: ±25ppm
• Operating Temperature Range: -40°C ~ 85°C
• Package / Case: 4-SMD, No Lead
• Size / Dimension: 0.126" L x 0.098" W (3.20mm x 2.50mm)
• Mounting Type: Surface Mount
• MSL Rating: 1 (Unlimited)

All identified substitute parts meet these mandatory criteria. Variations in current supply specifications, base resonator technology (MEMS versus Crystal), and product status (Obsolete versus Active) do not preclude substitution when all electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Part Replacement:

The TC-16.000MBD-T is classified as Obsolete. Both substitute parts—7X-16.000MBD-T and SXO32C3C481-16.000M—are Active status components and provide direct electrical and mechanical equivalence.

7X-16.000MBD-T (TXC CORPORATION):

• Maintains manufacturer continuity with the original part
• RoHS Compliant certification
• Supplied in Tape & Reel packaging
• Maximum supply current: 15mA (lower than original 25mA specification)
• Seated height: 0.043" (1.10mm), exceeds original 0.031" (0.80mm)

SXO32C3C481-16.000M (Suntsu Electronics, Inc.):

• ROHS3 Compliant certification
• Supplied in Bulk packaging
• Maximum supply current: 10mA (lowest among all options)
• Seated height: 0.047" (1.20mm), exceeds original 0.031" (0.80mm)

Selection between these substitutes depends on procurement requirements (packaging format), compliance certifications needed for the application, and physical space constraints within the target assembly. All three parts satisfy the core electrical and mechanical substitution criteria.

Frequently Asked Questions (FAQ)

Q: Can the 7X-16.000MBD-T directly replace the TC-16.000MBD-T in existing designs?

A: Yes. Both parts share identical electrical specifications (16 MHz, CMOS output, 3.3V supply, Enable/Disable function, ±25ppm stability, -40°C ~ 85°C operating range) and mechanical dimensions (0.126" L x 0.098" W, 4-SMD No Lead package). The 7X-16.000MBD-T is pin-compatible and functionally equivalent.

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

A: The TC-16.000MBD-T has a maximum seated height of 0.031" (0.80mm), while the 7X-16.000MBD-T measures 0.043" (1.10mm) and the SXO32C3C481-16.000M measures 0.047" (1.20mm). Height variations must be evaluated against PCB layout constraints and enclosure clearances. If the original design has minimal vertical clearance, the taller substitute parts may require mechanical redesign.

Q: Does the lower maximum supply current of the substitute parts affect circuit operation?

A: No. The substitute parts specify lower maximum supply current values (15mA for 7X-16.000MBD-T and 10mA for SXO32C3C481-16.000M) compared to the original 25mA specification. Lower maximum ratings indicate improved power efficiency and do not compromise functionality. The actual operating current depends on circuit design and load conditions.

Q: What is the difference between MEMS and Crystal-based oscillators in these parts?

A: The TC-16.000MBD-T uses MEMS (Micro-Electro-Mechanical Systems) resonator technology, while the 7X-16.000MBD-T and SXO32C3C481-16.000M use Crystal resonators. Both technologies deliver identical electrical performance for this application (16 MHz, ±25ppm stability). The choice between them is determined by availability and supply chain considerations rather than functional differences.

Q: Are there packaging format differences between the substitute parts?

A: Yes. The 7X-16.000MBD-T is supplied in Tape & Reel (TR) format, suitable for automated assembly processes. The SXO32C3C481-16.000M is supplied in Bulk format. Selection depends on production volume and assembly equipment compatibility.

Q: Do the RoHS compliance differences matter for substitution?

A: Both substitute parts carry RoHS compliance certifications (7X-16.000MBD-T is RoHS Compliant; SXO32C3C481-16.000M is ROHS3 Compliant). If the target application requires specific RoHS certification levels, verify alignment with system requirements. Both certifications satisfy standard environmental compliance requirements.
