• Supply Voltage: 3.3V (exact match required)
• Function: Enable/Disable (exact match required)
• Package Type: 4-SMD, No Lead (exact match required)
• Package Dimensions: 5.00mm x 3.20mm (exact match required)
• Mounting Type: Surface Mount (exact match required)

Secondary Compatibility Criteria (Allowable Variations):

• Frequency Stability: ±25ppm to ±100ppm (tighter or equivalent tolerance acceptable)
• Operating Temperature Range: -10°C ~ 70°C or wider range acceptable
• Maximum Supply Current: 30mA or lower acceptable
• Maximum Seated Height: 1.40mm or lower acceptable
• Product Status: Active preferred over Obsolete
• RoHS/REACH Compliance: Maintained across all substitutes

All substitute parts listed meet the primary compatibility criteria. Variations in secondary parameters are noted to support engineering selection based on specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Upgrade Path (Preferred): The 7C-50.000MBA-T (FTS) is the primary upgrade candidate. It maintains identical electrical specifications to the 7C-50.000MBB-T while offering improved frequency stability (±25ppm versus ±50ppm) and Active product status. This part is available in Tape & Reel packaging with 6798 units in stock, supporting high-volume production requirements.

Direct Equivalent (Same Manufacturer): The 7C50000015 (TXC CORPORATION) provides parametric equivalence with identical frequency stability (±50ppm) and operating temperature range. As an active product from the original manufacturer, this part maintains design continuity while ensuring ongoing availability.

Alternative Substitutes (Active Status): The 7C-50.000MBC-T (TXC CORPORATION) is an active alternative with relaxed frequency stability (±100ppm). This part is suitable for applications where tighter frequency tolerance is not required.

The SXO53C3A171-50.000M (Suntsu Electronics, Inc.) provides equivalent frequency stability (±50ppm) with reduced maximum supply current (25mA versus 30mA), supporting lower-power applications. ROHS3 compliance is maintained.

Extended Temperature Range Options: The CPPC5L-A3B6-50.0TS and CPPC5LZ-A7BP-50.0TS (Cardinal Components Inc.) offer extended operating temperature ranges (-55°C ~ 125°C and -40°C ~ 85°C respectively) for applications requiring broader thermal performance. The CPPFXC5LZ-A7BR-50.0TS provides the tightest frequency stability (±25ppm) among Cardinal Components offerings with -40°C ~ 85°C operating range.

Compliance Verification: All substitute parts maintain RoHS compliance. REACH compliance status is consistent across TXC CORPORATION and Cardinal Components parts. Suntsu Electronics parts carry ROHS3 designation. Moisture Sensitivity Level 1 (Unlimited) is maintained across all substitutes, supporting standard handling and storage procedures.

Frequently Asked Questions (FAQ)

Q: Can the 7C-50.000MBA-T directly replace the 7C-50.000MBB-T?

A: Yes. The 7C-50.000MBA-T meets all primary compatibility criteria: 50 MHz frequency, CMOS output, 3.3V supply, Enable/Disable function, 4-SMD No Lead package, and 5.00mm x 3.20mm dimensions. The improved frequency stability (±25ppm) is a performance enhancement. Electrical and mechanical compatibility is confirmed.

Q: What is the difference between ±50ppm and ±100ppm frequency stability?

A: Frequency stability tolerance defines the maximum deviation from the nominal 50 MHz frequency across operating conditions. ±50ppm allows deviation of ±2.5 kHz; ±100ppm allows ±5 kHz. Applications requiring precise frequency control (communications, test equipment) should use ±50ppm or tighter. General-purpose applications may accept ±100ppm.

Q: Are the Cardinal Components parts (CPPC5L, CPPC5LZ, CPPFXC5LZ series) compatible with the original design?

A: Yes, all Cardinal Components parts meet primary compatibility criteria. Physical dimensions are identical (5.00mm x 3.20mm). Maximum seated height is slightly lower (1.30mm versus 1.40mm), which is acceptable for PCB layout. Operating temperature ranges are extended, supporting broader application environments. Frequency stability options range from ±25ppm to ±100ppm.

Q: What is the significance of packaging type (Tape & Reel versus Bulk)?

A: Tape & Reel (TR) packaging is standard for automated assembly and high-volume production. Bulk packaging is used for lower-volume applications or manual assembly. The 7C-50.000MBA-T is available in Tape & Reel with 6798 units in stock, supporting production scalability. Electrical and mechanical specifications are identical regardless of packaging format.

Q: Can I use a part with lower maximum supply current (25mA versus 30mA)?

A: Yes, if your circuit design draws 25mA or less. Parts with lower maximum current ratings (SXO53C3A171-50.000M, Cardinal Components series) are suitable for power-constrained applications. Verify actual circuit current draw before substitution.

Q: Are all substitute parts RoHS compliant?

A: Yes. TXC CORPORATION and Cardinal Components parts carry RoHS Compliant designation. Suntsu Electronics parts carry ROHS3 Compliant designation. All parts meet RoHS requirements for hazardous substance restrictions.

Q: What is Moisture Sensitivity Level (MSL) 1?

A: MSL 1 indicates unlimited shelf life without moisture control. The component does not require special desiccant packaging or baking procedures before soldering. Standard handling and storage procedures are sufficient for all listed substitutes.

Q: Which substitute offers the best frequency stability?

A: The 7C-50.000MBA-T and CPPFXC5LZ-A7BR-50.0TS both offer ±25ppm frequency stability, the tightest tolerance among available substitutes. Selection between these depends on product status preference (Active from FTS versus Active from Cardinal Components) and packaging requirements.
