NE555PSRG4 Equivalent & Substitute Parts

Part Overview

The NE555PSRG4 is a 555 Type Timer/Oscillator (Single) IC operating at 100kHz, manufactured by Texas Instruments in an 8-SOIC surface mount package. This component is classified as Obsolete, which necessitates identification of active equivalent parts for ongoing design and procurement requirements. The NE555PSRG4 is supplied in Tape & Reel (TR) packaging and maintains full ROHS3 compliance with unlimited moisture sensitivity rating.

Substitute Part Grouping Explanation

Substitution of the NE555PSRG4 is determined by strict equivalence across the following critical parameters:

• Functional Type: 555 Type, Timer/Oscillator (Single) IC
• Frequency Rating: 100kHz
• Supply Voltage Range: 4.5V ~ 16V
• Supply Current: 10 mA
• Operating Temperature Range: 0°C ~ 70°C
• Package / Case: 8-SOIC (0.209", 5.30mm Width)
• Mounting Type: Surface Mount
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The NE555PSR meets all parametric requirements for direct substitution. The difference in packaging format (Cut Tape & Digi-Reel® versus Tape & Reel) does not affect electrical or mechanical compatibility, as both formats deliver the same component in the identical 8-SOIC package configuration.

Parameter Comparison

Engineering Selection Recommendations

The NE555PSR is the direct parametric equivalent for the obsolete NE555PSRG4. Both components are manufactured by Texas Instruments and share identical electrical specifications, package geometry, and compliance certifications. The NE555PSR maintains Active product status, ensuring continued availability and supply chain reliability. Selection of the NE555PSR eliminates obsolescence risk while preserving full functional and mechanical compatibility with existing PCB designs and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the NE555PSR be used as a direct replacement for the NE555PSRG4 on existing PCBs?

A: Yes. The NE555PSR is electrically and mechanically identical to the NE555PSRG4. Both components use the 8-SOIC package with identical pin configuration, supply voltage range, frequency rating, and operating temperature specifications. No PCB modifications are required.

Q: What is the difference between Tape & Reel (TR) and Cut Tape & Digi-Reel® packaging?

A: Both packaging formats deliver the same 8-SOIC component. Tape & Reel is continuous reel packaging for high-volume automated assembly. Cut Tape & Digi-Reel® provides smaller quantity formats. The component itself and its electrical performance are unchanged.

Q: Why is the NE555PSRG4 listed as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The NE555PSR remains in Active production and serves as the current equivalent for new designs and replacement procurement.

Q: Are there any compliance differences between the two parts?

A: No. Both the NE555PSRG4 and NE555PSR are ROHS3 Compliant, REACH Unaffected, and carry identical moisture sensitivity ratings (MSL 1 - Unlimited).

Q: What supply voltage range do these components support?

A: Both the NE555PSRG4 and NE555PSR operate across a 4.5V to 16V supply voltage range with a maximum supply current of 10 mA.
