Key Parameters

Substitute Part Grouping Explanation

Substitution of the NE555PWRE4 is determined by strict equivalence across the following critical parameters:

• Functional Type: 555 Type, Timer/Oscillator (Single)
• Frequency Rating: 100kHz
• Supply Voltage Range: 4.5V ~ 16V
• Supply Current: 10 mA
• Operating Temperature Range: 0°C ~ 70°C
• Package Configuration: 8-TSSOP surface mount
• Electrical Compliance: ROHS3 Compliant, REACH Unaffected

The NE555PWR meets all these parameters and is classified as a parametric equivalent. This part maintains identical electrical specifications and package footprint, enabling direct substitution in applications currently using the NE555PWRE4.

Parameter Comparison

Engineering Selection Recommendations

The NE555PWR is the direct parametric equivalent for the obsolete NE555PWRE4. Both parts are manufactured by Texas Instruments and share identical electrical specifications, frequency rating, supply voltage range, and 8-TSSOP package configuration. The primary distinction is product status: NE555PWRE4 is obsolete while NE555PWR maintains active production status.

For new designs or component replacement in existing applications, NE555PWR is the appropriate selection. This part carries ROHS3 compliance and REACH unaffected status, matching the regulatory requirements of the original part. The availability of NE555PWR (105,300 pcs in stock) ensures procurement continuity compared to the limited availability of the obsolete NE555PWRE4 variant.

Frequently Asked Questions (FAQ)

Q: Can NE555PWR be used as a direct replacement for NE555PWRE4?

A: Yes. Both parts are identical in electrical specifications, frequency rating, supply voltage range, current consumption, operating temperature range, and 8-TSSOP package footprint. No circuit modifications are required.

Q: What is the difference between NE555PWRE4 and NE555PWR?

A: The primary difference is packaging format and product status. NE555PWRE4 is obsolete, while NE555PWR is active production. NE555PWR is supplied in Cut Tape (CT) and Digi-Reel® packaging, whereas NE555PWRE4 packaging details were not specified. Electrical performance and package dimensions are identical.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant and REACH unaffected. Regulatory compliance is equivalent.

Q: What is the 8-TSSOP package?

A: 8-TSSOP (Thin Shrink Small Outline Package) is a surface mount package measuring 0.173 inches (4.40mm) in width. This package is standard for 555 timer ICs and ensures compatibility between equivalent parts using this configuration.

Q: Is the NE555PWR available in sufficient quantity?

A: Yes. NE555PWR has 105,300 pcs in new original stock, providing reliable procurement availability for production and replacement applications.
