Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BA1604 is determined by the following critical parameters:

• Functional equivalence: Both parts must perform tone decoding with PLL functionality
• Package compatibility: 8-DIP (0.300", 7.62mm) through-hole mounting required for direct PCB substitution
• Voltage supply range: Must operate within or encompass the 4.75V ~ 9V supply specification
• Number of circuits: Single circuit configuration mandatory
• Compliance standards: ROHS3 compliance and EAR99 classification required

The LM567CN/NOPB from Texas Instruments meets these core substitution criteria. Both parts share identical package geometry, voltage supply range, and functional classification as tone decoder ICs. Differences in current supply, power consumption, and operating temperature range represent secondary parameters that may influence selection based on specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the BA1604 and LM567CN/NOPB are active production components with ROHS3 compliance and EAR99 classification, making them suitable for equivalent substitution in telecom interface applications.

Selection between these parts should be based on application-specific constraints:

• Temperature range requirements: The BA1604 operates from -40°C to 85°C, providing extended low-temperature capability. The LM567CN/NOPB operates from 0°C to 70°C, suitable for standard industrial and commercial temperature environments.

• Power budget constraints: The BA1604 dissipates 350 mW at maximum supply current (10mA), while the LM567CN/NOPB dissipates 1.1 W at maximum supply current (12mA). Applications with strict thermal or power consumption limits should prioritize the BA1604.

• Supply chain availability: Current inventory shows 21,724 units of BA1604 and 1,695 units of LM567CN/NOPB. Selection may depend on procurement lead times and volume requirements.

Both parts maintain identical package geometry and voltage supply specifications, ensuring direct PCB-level compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the LM567CN/NOPB directly replace the BA1604 on an existing PCB?

A: Yes. Both parts use identical 8-DIP (0.300", 7.62mm) through-hole packaging and share the same pin configuration for tone decoder functionality. No PCB modifications are required for physical substitution.

Q: What are the key differences between these parts?

A: The primary differences are operating temperature range (BA1604: -40°C to 85°C vs. LM567CN/NOPB: 0°C to 70°C), power consumption (BA1604: 350 mW vs. LM567CN/NOPB: 1.1 W), and supply current (BA1604: 10mA vs. LM567CN/NOPB: 12mA). Both maintain identical voltage supply range (4.75V ~ 9V) and functional classification.

Q: Are both parts RoHS compliant?

A: Yes. Both the BA1604 and LM567CN/NOPB are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: Which part should I select for low-temperature applications?

A: The BA1604 is specified for operation down to -40°C, making it the appropriate choice for applications requiring extended low-temperature performance. The LM567CN/NOPB is rated to 0°C minimum.

Q: Are there any supply voltage compatibility issues?

A: No. Both parts operate within the identical 4.75V ~ 9V supply range, ensuring full voltage compatibility across standard telecom interface power specifications.

Q: What is the significance of the different power ratings?

A: The BA1604 dissipates 350 mW while the LM567CN/NOPB dissipates 1.1 W under maximum operating conditions. Applications with thermal constraints or battery-powered systems should prioritize the lower-power BA1604.
