NE555V Equivalent & Substitute Parts

Part Overview

The NE555V is a 555 Type Timer/Oscillator (Single) IC manufactured by Texas Instruments, operating at 100kHz with a supply voltage range of 4.5V to 16V. This component is classified as Obsolete, which necessitates identification of equivalent substitute parts for ongoing design requirements and production continuity. The NE555V is packaged in an 8-DIP (0.300", 7.62mm) through-hole configuration and is RoHS non-compliant.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the NE555V are identified based on strict equivalence of the following electrical and mechanical parameters:

• Type: 555 Type, Timer/Oscillator (Single)
• Frequency: 100kHz
• Voltage - Supply: 4.5V ~ 16V
• Current - Supply: 10 mA
• Operating Temperature: 0°C ~ 70°C
• Package / Case: 8-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole

Two substitute parts meet these criteria: LM555CN/NOPB and NE555P. Both maintain identical electrical specifications and mechanical packaging, ensuring functional compatibility in applications designed for the NE555V.

Parameter Comparison

Engineering Selection Recommendations

Both LM555CN/NOPB and NE555P are functionally equivalent to the NE555V based on electrical and mechanical parameters. Selection between these substitutes should consider the following factors:

LM555CN/NOPB is an Active product with ROHS3 compliance and maintains MSL 1 (Unlimited) rating, offering compliance with modern environmental standards while preserving moisture handling characteristics equivalent to the original part.

NE555P is an Active product with ROHS3 compliance and carries an MSL rating of Not Applicable, indicating different moisture sensitivity classification. This part maintains the NE555 base product number lineage.

Both substitutes are supplied by Texas Instruments and are available in Tube packaging. The choice between them depends on specific compliance requirements and supply chain considerations for the application.

Frequently Asked Questions (FAQ)

Q: Can LM555CN/NOPB and NE555P be used interchangeably with NE555V?

A: Yes. Both parts maintain identical electrical specifications (frequency, supply voltage, current, operating temperature) and mechanical packaging (8-DIP through-hole). They are functionally equivalent for applications designed for the NE555V.

Q: What is the primary reason for substituting the NE555V?

A: The NE555V is classified as Obsolete. LM555CN/NOPB and NE555P are Active products, ensuring ongoing availability and supply chain continuity.

Q: Are there compliance differences between the substitute parts?

A: Both LM555CN/NOPB and NE555P are ROHS3 compliant, whereas the NE555V is RoHS non-compliant. For applications requiring RoHS compliance, either substitute is suitable. MSL ratings differ: LM555CN/NOPB maintains MSL 1 (Unlimited), while NE555P carries Not Applicable classification.

Q: Do the substitute parts require PCB layout modifications?

A: No. Both LM555CN/NOPB and NE555P use the identical 8-DIP (0.300", 7.62mm) through-hole package, requiring no changes to PCB footprints or mounting procedures.

Q: What is the inventory status of the substitute parts?

A: LM555CN/NOPB has 2220 pieces in stock. NE555P has 156300 pieces in stock, indicating strong availability for both options.
