Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BBA5500005 are qualified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Critical Matching Parameters:

• Frequency: 155.52 MHz (exact match required)
• Output Type: LVPECL (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Function: Enable/Disable (exact match required)
• Frequency Stability: ±20ppm (exact match required)
• Operating Temperature Range: -20°C ~ 70°C (exact match required)
• Package / Case: 6-SMD, No Lead (exact match required)
• Physical Dimensions: 0.276" L x 0.197" W / 7.00mm x 5.00mm (exact match required)
• Base Resonator: Crystal (exact match required)
• Type: XO (Standard) (exact match required)

The SXO75P3D271-155.520M from Suntsu Electronics, Inc. meets all critical electrical and mechanical parameters, qualifying it as a direct substitute for the BBA5500005.

Parameter Comparison

Engineering Selection Recommendations

Both the BBA5500005 and SXO75P3D271-155.520M are Active status products with full regulatory compliance. The BBA5500005 carries RoHS Compliant certification, while the SXO75P3D271-155.520M carries ROHS3 Compliant certification, representing an enhanced compliance level. Both devices share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

The primary physical difference is the seated height: the BBA5500005 measures 0.059" (1.50mm) maximum, while the SXO75P3D271-155.520M measures 0.067" (1.70mm) maximum. This 0.008" (0.20mm) height differential must be evaluated against PCB layout constraints and clearance requirements in the target application.

The SXO75P3D271-155.520M specifies a maximum supply current of 80mA, whereas the BBA5500005 does not provide this specification. Both parts maintain identical electrical performance parameters: 155.52 MHz frequency, LVPECL output, 3.3V supply, Enable/Disable function, ±20ppm frequency stability, and -20°C ~ 70°C operating temperature range.

Selection between these parts should be based on physical height constraints and current budget requirements specific to the application circuit.

Frequently Asked Questions (FAQ)

Q: Can the SXO75P3D271-155.520M directly replace the BBA5500005 in existing designs?

A: The SXO75P3D271-155.520M meets all critical electrical parameters and package specifications. However, the seated height difference of 0.008" (0.20mm) must be verified against PCB layout clearances. If vertical clearance is not constrained, direct substitution is permissible.

Q: What are the key parameters that define substitution eligibility for this oscillator?

A: Substitution eligibility is determined by exact matching of: frequency (155.52 MHz), output type (LVPECL), supply voltage (3.3V), function (Enable/Disable), frequency stability (±20ppm), operating temperature range (-20°C ~ 70°C), package type (6-SMD, No Lead), and physical dimensions (0.276" L x 0.197" W / 7.00mm x 5.00mm).

Q: Are there compliance differences between the BBA5500005 and SXO75P3D271-155.520M?

A: The BBA5500005 is RoHS Compliant, while the SXO75P3D271-155.520M is ROHS3 Compliant. ROHS3 represents an updated compliance standard. Both devices are EAR99 classified and share identical HTSUS codes.

Q: What is the significance of the current specification difference?

A: The SXO75P3D271-155.520M specifies 80mA maximum supply current, while the BBA5500005 does not provide this specification. In power-sensitive applications, the SXO75P3D271-155.520M current specification provides explicit design guidance for power supply sizing and thermal management calculations.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both the BBA5500005 and SXO75P3D271-155.520M operate across the identical temperature range of -20°C ~ 70°C with ±20ppm frequency stability maintained throughout this range.

Q: What packaging formats are available for these oscillators?

A: Both parts are supplied in 6-SMD, No Lead surface mount packages with identical footprint dimensions of 0.276" L x 0.197" W (7.00mm x 5.00mm). The BBA5500005 is available in standard packaging, while the SXO75P3D271-155.520M is available in Bulk packaging.
