Parameter Comparison

Engineering Selection Recommendations

CBA3300002 (TXC CORPORATION): This part is a parametric equivalent manufactured by the same supplier as the main part. It maintains identical electrical and mechanical specifications across all critical parameters. The part carries Active product status, ensuring long-term availability and supply chain continuity. RoHS Compliance and REACH Unaffected status align with the original part. This substitute is the primary choice for direct replacement in designs currently using CB-133.330MBE-T.

NX5021E0133.330000 (Diodes Incorporated): This part is a direct manufacturer equivalent from Diodes Incorporated, operating under the SaRonix-eCera™ NX product line. It meets all electrical specifications including frequency, output type, supply voltage, and operating temperature range. The package dimensions and mounting type are identical. The maximum seated height is 1.35mm compared to 1.40mm for the main part, representing a 0.05mm reduction that remains within typical PCB assembly tolerances. ROHS3 Compliance provides enhanced environmental standards. This substitute offers an alternative source for supply diversification.

Both substitutes are qualified for direct replacement based on electrical and mechanical parameter equivalence.

Frequently Asked Questions (FAQ)

Q: Can CBA3300002 be used as a direct replacement for CB-133.330MBE-T?

A: Yes. CBA3300002 is a parametric equivalent with identical electrical specifications (133.33 MHz, LVPECL, 3.3V, Enable/Disable, ±50ppm stability, -40°C ~ 85°C operating range) and mechanical specifications (6-SMD No Lead package, 5.00mm x 3.20mm dimensions, 1.40mm maximum height). Both parts are manufactured by TXC CORPORATION and share identical compliance certifications.

Q: What is the difference between CBA3300002 and NX5021E0133.330000?

A: Both parts are electrical equivalents with identical frequency, output type, supply voltage, and operating temperature specifications. The primary differences are: (1) Manufacturer—CBA3300002 is from TXC CORPORATION; NX5021E0133.330000 is from Diodes Incorporated; (2) Maximum seated height—CBA3300002 is 1.40mm; NX5021E0133.330000 is 1.35mm; (3) RoHS certification level—CBA3300002 is RoHS Compliant; NX5021E0133.330000 is ROHS3 Compliant; (4) Packaging—NX5021E0133.330000 is supplied in Tape & Reel format.

Q: Is the 0.05mm height difference between CBA3300002 and NX5021E0133.330000 significant?

A: The 0.05mm height difference (1.40mm versus 1.35mm) is within standard PCB assembly tolerances and does not affect mechanical compatibility or board-level integration. Both parts fit within the same footprint and mounting envelope.

Q: Are all three parts RoHS compliant?

A: Yes. CB-133.330MBE-T and CBA3300002 carry RoHS Compliant certification. NX5021E0133.330000 carries ROHS3 Compliant certification, which represents an enhanced environmental standard. All three parts are REACH Unaffected.

Q: What is the current supply specification for each part?

A: CB-133.330MBE-T specifies 80mA maximum supply current. NX5021E0133.330000 also specifies 80mA maximum supply current. CBA3300002 does not specify maximum supply current in the provided data. For designs with strict current budgeting, NX5021E0133.330000 provides explicit current specification matching the original part.

Q: Can these parts be used interchangeably in production?

A: Yes, within the constraints of your supply chain and qualification procedures. All three parts meet identical electrical and mechanical specifications for the 133.33 MHz LVPECL oscillator function. CBA3300002 is recommended as the primary substitute due to identical manufacturer and specifications. NX5021E0133.330000 is suitable for supply diversification and alternative sourcing.
