Substitute Part Grouping Explanation

Substitution of the RC4136NG4 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Amplifier Type: General Purpose
• Number of Circuits: 4 independent channels
• Slew Rate: 1.7 V/µs
• Gain Bandwidth Product: 3 MHz
• Current - Input Bias: 140 nA
• Voltage - Input Offset: 500 µV
• Current - Supply: 5 mA per channel
• Voltage - Supply Span: 10V minimum to 30V maximum

Mechanical Equivalence Criteria:

• Package / Case: 14-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole
• Supplier Device Package: 14-PDIP

The RC4136N qualifies as a direct substitute based on identical electrical specifications and mechanical packaging. The primary distinction is product status and packaging format.

Engineering Selection Recommendations

The RC4136N is the direct functional equivalent of the RC4136NG4. Both components share identical electrical performance specifications and mechanical packaging. The RC4136N is the preferred selection for new designs and ongoing procurement due to its active product status, ensuring long-term availability and manufacturing support from Texas Instruments.

The RC4136NG4, classified as obsolete, should be replaced with the RC4136N in applications where component refresh or redesign is feasible. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and commercial applications.

The difference in packaging format (RC4136NG4 supplied in ceramic DIP versus RC4136N supplied in tube packaging) does not affect electrical or mechanical compatibility in through-hole PCB assembly applications.

Frequently Asked Questions (FAQ)

Q: Can RC4136N be used as a direct replacement for RC4136NG4 in existing circuit designs?

A: Yes. The RC4136N is electrically and mechanically equivalent to the RC4136NG4. All electrical parameters, including slew rate, gain bandwidth product, input bias current, and supply voltage range, are identical. Both components use the same 14-DIP through-hole package.

Q: What is the primary reason for substituting RC4136NG4 with RC4136N?

A: The RC4136NG4 is classified as obsolete, while the RC4136N maintains active product status. This ensures continued availability, manufacturing support, and compliance with current industry standards from Texas Instruments.

Q: Are there any differences in packaging that affect PCB assembly?

A: The RC4136NG4 and RC4136N both use 14-DIP (0.300", 7.62mm) through-hole packages. The primary packaging difference is the supplier format: RC4136NG4 uses ceramic DIP packaging, while RC4136N is supplied in tube format. This does not affect PCB assembly compatibility or electrical performance.

Q: Do both parts meet current regulatory compliance requirements?

A: Yes. Both the RC4136NG4 and RC4136N are ROHS3 compliant and REACH unaffected, satisfying regulatory requirements for industrial and commercial applications.

Q: What are the key electrical parameters that define substitution compatibility?

A: Substitution compatibility is determined by four-channel general-purpose amplifier configuration, 1.7 V/µs slew rate, 3 MHz gain bandwidth product, 140 nA input bias current, 500 µV input offset voltage, 5 mA supply current per channel, and 10V to 30V supply voltage range.

Q: Is the RC4136N suitable for applications originally designed for RC4136NG4?

A: Yes. The RC4136N is suitable for all applications originally designed for the RC4136NG4, provided the operating temperature range (0°C to 70°C) and supply voltage specifications (10V to 30V) are maintained within design parameters.
