Engineering Selection Recommendations
Primary Upgrade Path (Same Manufacturer):
The 7C-16.000MBA-T represents the direct upgrade from the obsolete 7C-16.000MBB-T. Both parts are manufactured by TXC CORPORATION, share identical physical dimensions, package type, and operating temperature range. The 7C-16.000MBA-T offers improved frequency stability (±25ppm versus ±50ppm) while maintaining all other electrical specifications. This part is currently in active production status with 946 units in stock.
Alternative Selection (Same Specifications, Different Manufacturer):
The SXO53C3A171-16.000M from Suntsu Electronics, Inc. provides functional equivalence with matching frequency stability (±50ppm) and operating temperature range. This part demonstrates lower maximum supply current (16mA versus 30mA), representing improved power efficiency. The SXO53C3A171-16.000M is ROHS3 compliant and maintains the same 4-SMD, No Lead package footprint. Inventory availability is substantial at 6814 units.
Extended Temperature Range Options:
The CPPC5L-A3B6-16.0TS and CPPLC5LZ-A7BR-16.0TS from Cardinal Components Inc. extend the operating temperature range to -55°C ~ 125°C and -40°C ~ 85°C respectively, accommodating applications requiring broader thermal performance. Both parts maintain 3.3V supply voltage, CMOS output, and 4-SMD, No Lead package compatibility. The CPPLC5LZ-A7BR-16.0TS offers ±25ppm frequency stability matching the TXC upgrade option.
Specification Trade-off Option:
The 7C-16.000MBC-T from TXC CORPORATION provides an active-status alternative with relaxed frequency stability (±100ppm) and highest inventory availability (1096 units). This part is suitable for applications where tighter frequency tolerance is not required.
All recommended substitutes maintain RoHS compliance and MSL 1 moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage protocols.
Frequently Asked Questions (FAQ)
Q: Can the 7C-16.000MBA-T directly replace the 7C-16.000MBB-T without circuit modification?
A: Yes. The 7C-16.000MBA-T is a direct functional replacement. Both parts share identical physical dimensions (5.00mm x 3.20mm), package type (4-SMD, No Lead), supply voltage (3.3V), frequency (16 MHz), and operating temperature range (-10°C ~ 70°C). The improved frequency stability (±25ppm) of the MBA-T variant is a performance enhancement that does not require circuit changes.
Q: What is the difference between the TXC 7C series variants (MBB-T, MBA-T, MBC-T)?
A: The three TXC variants differ in frequency stability specification. The 7C-16.000MBB-T (obsolete) specifies ±50ppm, the 7C-16.000MBA-T (active) specifies ±25ppm, and the 7C-16.000MBC-T (active) specifies ±100ppm. All other electrical and physical parameters remain identical. Selection depends on the frequency tolerance requirements of the target application.
Q: Is the SXO53C3A171-16.000M from Suntsu Electronics compatible with the original 7C-16.000MBB-T?
A: Yes, the SXO53C3A171-16.000M is compatible. Both parts operate at 16 MHz with ±50ppm frequency stability, 3.3V supply voltage, CMOS output, and identical 4-SMD, No Lead package dimensions. The Suntsu part offers lower supply current (16mA maximum versus 30mA), which may provide power consumption benefits in the target application.
Q: Can Cardinal Components CPPC5L-A3B6-16.0TS be used in applications requiring the original -10°C ~ 70°C temperature range?
A: Yes. The CPPC5L-A3B6-16.0TS operates across -55°C ~ 125°C, which encompasses the original -10°C ~ 70°C specification. The extended temperature range does not create incompatibility; it represents expanded operational capability. However, the frequency stability is ±100ppm, which is looser than the original ±50ppm specification.
Q: What is the advantage of the CPPLC5LZ-A7BR-16.0TS over other Cardinal Components options?
A: The CPPLC5LZ-A7BR-16.0TS combines ±25ppm frequency stability (matching the TXC MBA-T upgrade) with an extended operating temperature range of -40°C ~ 85°C. This part is suitable for applications requiring both improved frequency accuracy and broader thermal performance compared to the original specification.
Q: Are all substitute parts RoHS compliant?
A: Yes. All listed substitute parts maintain RoHS compliance (either RoHS or ROHS3 standard). The original 7C-16.000MBB-T is RoHS Compliant, and all substitute options maintain this certification status, ensuring compatibility with RoHS-regulated supply chains and manufacturing environments.
Q: What packaging formats are available for these oscillators?
A: The 7C-16.000MBB-T is supplied in standard packaging (format not specified). The 7C-16.000MBA-T is available in Tape & Reel (TR) format. The SXO53C3A171-16.000M is supplied in Bulk format. Cardinal Components parts (CPPC5L-A3B6-16.0TS and CPPLC5LZ-A7BR-16.0TS) are available in Tape & Reel (TR) format. All packaging formats are functionally equivalent for component selection purposes; packaging choice depends on production volume and assembly process requirements.
Q: Is moisture sensitivity a concern when substituting these parts?
A: No. All listed parts maintain MSL 1 (Unlimited) moisture sensitivity level, indicating no special moisture control requirements during storage or handling. This specification is consistent across the original part and all substitutes, eliminating moisture management as a substitution consideration.
