CBA2570001 Equivalent & Substitute Parts

Part Overview

The CBA2570001 is a 125 MHz XO (Standard) LVPECL oscillator manufactured by TXC CORPORATION. This crystal-based oscillator operates at 3.3V with enable/disable functionality, housed in a 6-SMD, No Lead surface mount package. The device is designed for applications requiring stable, low-voltage positive emitter-coupled logic output at 125 MHz frequency.

The CBA2570001 is classified as an active product with full RoHS compliance and unlimited moisture sensitivity level (MSL 1). Identifying equivalent substitute parts is necessary for supply chain continuity, inventory optimization, and design flexibility when the primary part becomes unavailable or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CBA2570001 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 125 MHz (exact match required)
• Output Type: LVPECL (logic family compatibility)
• Supply Voltage: 3.3V (electrical compatibility)
• Function: Enable/Disable (feature parity)
• Frequency Stability: ±50ppm (performance specification)
• Operating Temperature Range: -40°C ~ 85°C (environmental specification)
• Package / Case: 6-SMD, No Lead (mechanical and electrical interface)
• Physical Dimensions: 5.00mm x 3.20mm (PCB layout compatibility)

The substitute part SXO53P3A481-125.000M from Suntsu Electronics, Inc. meets all mandatory matching parameters and is therefore classified as a direct equivalent substitute.

Engineering Selection Recommendations

CBA2570001 (TXC CORPORATION):

• Primary selection for existing designs and established supply chains
• Active product status with confirmed availability (898 Pcs in stock)
• RoHS Compliant certification
• MSL 1 rating provides unlimited shelf life
• Suitable for applications where TXC qualification is required

SXO53P3A481-125.000M (Suntsu Electronics, Inc.):

• Direct substitute when CBA2570001 supply is constrained
• Active product status with higher inventory availability (2559 Pcs in stock)
• ROHS3 Compliant certification (meets current RoHS standards)
• Lower seated height (1.20mm vs 1.40mm) provides design flexibility for space-constrained applications
• Specified maximum supply current of 80mA enables power budget verification
• Bulk packaging option available

Both parts are classified as active products with full regulatory compliance. Selection between these parts should be based on supply availability, inventory requirements, and design-specific constraints such as PCB height clearance.

Frequently Asked Questions (FAQ)

Q: Can SXO53P3A481-125.000M be used as a direct replacement for CBA2570001 in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters: 125 MHz frequency, LVPECL output, 3.3V supply, enable/disable function, ±50ppm stability, -40°C to 85°C operating range, and 6-SMD, No Lead package with 5.00mm x 3.20mm footprint. No design modifications are required for substitution.

Q: What is the difference in physical height between these two parts?

A: The CBA2570001 has a maximum seated height of 1.40mm, while the SXO53P3A481-125.000M has a maximum seated height of 1.20mm. The Suntsu part is 0.20mm lower, which may be advantageous in applications with tight vertical clearance constraints.

Q: Are there any compliance or certification differences?

A: Both parts are RoHS compliant. The CBA2570001 carries RoHS Compliant certification, while the SXO53P3A481-125.000M carries ROHS3 Compliant certification. Both meet current regulatory requirements. Both parts are REACH Unaffected or equivalent, and both carry ECCN EAR99 classification.

Q: What is the moisture sensitivity level (MSL) for the Suntsu substitute?

A: The MSL rating for SXO53P3A481-125.000M is not provided in the available specifications. The CBA2570001 carries MSL 1 (Unlimited), indicating no moisture sensitivity constraints. Verify MSL requirements with the component supplier if moisture exposure during storage or handling is a concern.

Q: Is the supply current specification important for my application?

A: The SXO53P3A481-125.000M specifies a maximum supply current of 80mA. The CBA2570001 does not provide this specification. If your design includes power budget calculations or current limiting circuits, use the 80mA specification for the Suntsu part. Verify the actual current draw through testing if the CBA2570001 specification becomes available.

Q: Can these parts be used interchangeably in production?

A: Yes, provided that your design does not include manufacturer-specific qualifications or certifications. Both parts meet the same electrical and mechanical specifications for this 125 MHz LVPECL oscillator category. Verify that your procurement and quality procedures allow cross-manufacturer substitution.
