Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD74HC4046ANSRE4 is determined by strict equivalence across the following critical parameters:

• Maximum operating frequency: 38MHz
• Input/Output signal type: CMOS/CMOS
• Input-to-output ratio: 1:4
• Supply voltage range: 2V ~ 6V
• Operating temperature range: -55°C ~ 125°C
• Package type: 16-SOIC (0.209", 5.30mm Width)
• Base product series: 74HC4046

The CD74HC4046ANSR qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is packaging format (Tape & Reel versus individual packaging) and product status (Active versus Discontinued).

Parameter Comparison

Engineering Selection Recommendations

The CD74HC4046ANSR is the direct equivalent for the CD74HC4046ANSRE4. Both parts share identical electrical characteristics, functional specifications, and physical packaging. The CD74HC4046ANSR maintains active product status with Texas Instruments and carries equivalent compliance certifications (ROHS3 Compliant, REACH Unaffected, MSL 1).

The primary consideration for selection is packaging format. The CD74HC4046ANSR is supplied in Tape & Reel format, which is standard for high-volume production environments. If individual packaging is required, alternative sourcing channels or bulk tape-and-reel procurement with subsequent reeling may be necessary.

Both parts are suitable for applications requiring Phase Lock Loop functionality in the 38MHz frequency range with CMOS-level signaling and supply voltages between 2V and 6V.

Frequently Asked Questions (FAQ)

Q: Can the CD74HC4046ANSR be used as a direct replacement for the CD74HC4046ANSRE4?

A: Yes. Both parts are electrically and functionally identical. They share the same maximum frequency (38MHz), input/output characteristics (CMOS/CMOS), supply voltage range (2V ~ 6V), operating temperature range (-55°C ~ 125°C), and 16-SOIC package configuration.

Q: What is the difference between these two part numbers?

A: The primary difference is packaging format. The CD74HC4046ANSRE4 uses individual packaging, while the CD74HC4046ANSR is supplied in Tape & Reel format. The CD74HC4046ANSR also maintains active product status, whereas the CD74HC4046ANSRE4 is discontinued at DiGi Electronics.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical compliance certifications: ROHS3 Compliant, REACH Unaffected, and Moisture Sensitivity Level 1 (Unlimited).

Q: Will the Tape & Reel packaging affect circuit board assembly?

A: No. The physical component itself is identical. Tape & Reel packaging is a supply format used for automated pick-and-place assembly. The actual 16-SOIC package dimensions and pin configuration remain unchanged.

Q: What are the critical parameters for substitution?

A: Substitution is valid when the following parameters match: maximum frequency (38MHz), input/output type (CMOS/CMOS), input-to-output ratio (1:4), supply voltage range (2V ~ 6V), operating temperature range (-55°C ~ 125°C), and package type (16-SOIC).
