Engineering Selection Recommendations
8W-4.000MBE-T (TXC CORPORATION)
Primary selection for applications where bulk packaging is acceptable. This part maintains active production status with 916 units currently in inventory. All regulatory compliance requirements are met, including ROHS3 compliance and REACH unaffected status. The part operates within specified frequency stability and temperature range parameters.
625L3I004M00000 (CTS-Frequency Controls)
Direct functional equivalent suitable for applications requiring Tape & Reel packaging format. This part is available in higher inventory volume (21,837 units) and provides identical electrical performance across all core parameters. The seated height is 1.00mm compared to 0.90mm for the primary part; this variation is acceptable for standard PCB assembly processes. Current supply specifications are identical at 15mA maximum. All regulatory certifications match the primary part.
ECS-2033-040-BN (ECS Inc.)
Parametric equivalent offering reduced maximum supply current of 7mA compared to 15mA for the primary part, representing a 53% reduction in power consumption. This part is supplied in Tape & Reel packaging and maintains identical seated height of 0.90mm. The lower current specification makes this part suitable for power-constrained applications. All regulatory compliance requirements are met. Inventory availability is 6,401 units.
All three parts are active products with current production status and meet all mandatory regulatory and compliance requirements for direct substitution.
Frequently Asked Questions (FAQ)
Q: Can the 625L3I004M00000 be used as a direct replacement for the 8W-4.000MBE-T?
A: Yes. The 625L3I004M00000 meets all core compatibility parameters including frequency, output type, supply voltage, function, frequency stability, operating temperature range, package type, and physical dimensions. The primary difference is packaging format (Tape & Reel versus bulk) and seated height (1.00mm versus 0.90mm), both of which are acceptable variations for standard applications.
Q: What is the advantage of selecting the ECS-2033-040-BN?
A: The ECS-2033-040-BN provides identical functional performance with reduced maximum supply current of 7mA compared to 15mA for the primary part. This 53% reduction in power consumption is beneficial for battery-powered or power-constrained applications. The part maintains all other electrical and mechanical specifications.
Q: Are there any height restrictions that would prevent using the 625L3I004M00000?
A: The 625L3I004M00000 has a maximum seated height of 1.00mm compared to 0.90mm for the 8W-4.000MBE-T. This 0.10mm difference is within standard PCB assembly tolerances and does not present a restriction for typical applications. Verify clearance requirements for specific board designs with minimal vertical space.
Q: Do all substitute parts have the same frequency stability?
A: Yes. All three parts specify ±50ppm frequency stability across the operating temperature range of -40°C to 85°C.
Q: What is the difference between bulk and Tape & Reel packaging?
A: The 8W-4.000MBE-T is supplied in bulk packaging, while the 625L3I004M00000 and ECS-2033-040-BN are supplied in Tape & Reel format. Tape & Reel packaging is standard for automated assembly processes and provides better handling and traceability. Bulk packaging is suitable for manual assembly or lower-volume applications. Both formats contain identical components.
Q: Are all parts RoHS3 compliant?
A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
Q: Can I mix these parts within the same production batch?
A: Yes. All three parts are functionally equivalent and meet identical electrical specifications. They can be used interchangeably within the same design. However, verify that your assembly process can accommodate both bulk and Tape & Reel formats if sourcing from multiple suppliers.
Q: What is the Moisture Sensitivity Level for these parts?
A: All three parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
