BAA5670001 156.25 MHz LVPECL Crystal Oscillator Equivalent & Substitute Parts

Part Overview

The BAA5670001 is a 156.25 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 classified as Active product status and is RoHS Compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the critical operating parameters: frequency (156.25 MHz), output standard (LVPECL), supply voltage (3.3V), function (Enable/Disable), frequency stability (±50ppm), operating temperature range (-40°C ~ 85°C), and package form factor (6-SMD, No Lead, 7.00mm x 5.00mm).

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BAA5670001 is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must match exactly or exceed the main part specifications:

Mandatory Matching Parameters:

• Frequency: 156.25 MHz (exact match required)
• Output Standard: LVPECL (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Function: Enable/Disable (exact match required)
• Frequency Stability: ±50ppm (substitute must meet or exceed this specification)
• Operating Temperature Range: -40°C ~ 85°C (substitute must cover this range)
• Package/Case: 6-SMD, No Lead (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Base Resonator: Crystal (exact match required)
• Type: XO (Standard) (exact match required)

Variable Parameters (Non-Critical for Substitution):

• Current Supply (Max): Varies by manufacturer (50mA to 80mA)
• Height - Seated (Max): Varies within tolerance (1.47mm to 1.70mm)
• Packaging Format: Tape & Reel or Bulk
• Manufacturer: TXC CORPORATION, Connor Winfield, EPSON, or Suntsu Electronics, Inc.

All identified substitute parts meet these mandatory criteria and are therefore electrically and mechanically interchangeable with the BAA5670001.

Parameter Comparison

Engineering Selection Recommendations

All four oscillators listed in this reference—BAA5670001, PB223-156.25M, SG7050EEN 156.2500M-CJGA3, and SXO75P3A481-156.250M—are classified as Active product status and meet current regulatory compliance requirements.

Compliance Considerations:

The BAA5670001 carries RoHS Compliant certification. The three substitute parts (PB223-156.25M, SG7050EEN 156.2500M-CJGA3, and SXO75P3A481-156.250M) are ROHS3 Compliant, which represents an updated compliance standard and is acceptable for applications requiring RoHS compliance.

All parts carry MSL 1 (Unlimited) moisture sensitivity rating, indicating no special moisture handling requirements during storage or assembly.

The BAA5670001 and PB223-156.25M are explicitly marked as REACH Unaffected. The SG7050EEN 156.2500M-CJGA3 is also REACH Unaffected. All parts carry EAR99 ECCN classification and 8542.39.0001 HTSUS code.

Supply Current Considerations:

Current supply specifications vary among the parts. The BAA5670001 does not specify maximum supply current. The PB223-156.25M specifies 50mA maximum. The SG7050EEN 156.2500M-CJGA3 specifies 60mA maximum with 25mA maximum in disable mode. The SXO75P3A481-156.250M specifies 80mA maximum. Applications with strict power budget constraints should account for these variations.

Physical Dimensions:

All parts share identical footprint dimensions (7.00mm x 5.00mm). Height variations range from 1.47mm to 1.70mm. Applications with height-constrained PCB layouts should verify clearance against the specific substitute part selected.

Frequently Asked Questions (FAQ)

Q: Can I substitute the BAA5670001 with any of the listed parts?

A: Yes. All listed substitute parts (PB223-156.25M, SG7050EEN 156.2500M-CJGA3, and SXO75P3A481-156.250M) meet the mandatory electrical and mechanical parameters required for direct substitution. They operate at identical frequency (156.25 MHz), output standard (LVPECL), supply voltage (3.3V), function (Enable/Disable), frequency stability (±50ppm), and temperature range (-40°C ~ 85°C). All use the same 6-SMD, No Lead package with 7.00mm x 5.00mm footprint.

Q: What are the key differences between the substitute parts?

A: The primary differences are manufacturer identity, maximum supply current specification, and seated height. The PB223-156.25M specifies 50mA maximum current and 1.47mm height. The SG7050EEN 156.2500M-CJGA3 specifies 60mA maximum current, 25mA disable current, and 1.70mm height. The SXO75P3A481-156.250M specifies 80mA maximum current and 1.70mm height. All other electrical parameters are identical.

Q: Are there packaging format differences?

A: Yes. The BAA5670001 is available in standard packaging format (not specified as Tape & Reel or Bulk). The PB223-156.25M is supplied in Tape & Reel format. The SG7050EEN 156.2500M-CJGA3 is supplied in Tape & Reel format. The SXO75P3A481-156.250M is supplied in Bulk format. Packaging format does not affect electrical or mechanical compatibility; it only affects procurement and handling logistics.

Q: Do all parts meet RoHS compliance?

A: Yes. The BAA5670001 is RoHS Compliant. The three substitute parts are ROHS3 Compliant, which represents the current RoHS standard and is acceptable for all applications requiring RoHS compliance.

Q: What is the moisture sensitivity level for these oscillators?

A: All four parts carry MSL 1 (Unlimited) rating, indicating unlimited shelf life without special moisture control measures. No baking or desiccant storage is required.

Q: Can I use these parts interchangeably on the same PCB?

A: Yes, from an electrical and mechanical standpoint. All parts share identical footprint (7.00mm x 5.00mm) and pinout configuration. However, verify that PCB clearance accommodates the maximum seated height of 1.70mm if using the taller substitute parts (SG7050EEN or SXO75P3A481) in space-constrained applications.

Q: Which substitute part should I select for lowest power consumption?

A: The PB223-156.25M specifies the lowest maximum supply current at 50mA. However, the BAA5670001 does not specify maximum current, so direct power consumption comparison is not possible. For applications with strict power budgets, contact the manufacturer for BAA5670001 current specifications.

Q: Are these parts suitable for high-reliability applications?

A: All parts are classified as Active product status with established supply chains. All carry standard industrial certifications (RoHS/ROHS3, REACH Unaffected, EAR99 ECCN). Specific reliability requirements (such as MIL-grade qualification or burn-in testing) should be confirmed directly with manufacturers or authorized distributors.
