Substitute Part Grouping Explanation

Substitution for the 74HC160D,653 is determined by strict adherence to the following critical parameters:

Core Functional Requirements:

• Logic Type: Counter, Decade (4-bit)
• Number of Elements: 1
• Number of Bits per Element: 4
• Direction: Up
• Reset: Asynchronous
• Timing: Synchronous
• Trigger Type: Positive Edge

Electrical Compatibility:

• Voltage Supply Range: 2 V ~ 6 V (minimum overlap required)
• Operating Temperature Range: Must encompass or match the application requirement

Physical & Compliance Requirements:

• Package / Case: 16-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Parameter Comparison

Engineering Selection Recommendations

The MC74HC160ADR2G from onsemi is a direct functional equivalent to the 74HC160D,653. Both components share identical logic architecture, electrical specifications, and package form factor. The onsemi variant provides an extended operating temperature range (-55°C to 125°C versus -40°C to 125°C), which offers additional margin for applications operating at lower ambient temperatures.

Both parts maintain ROHS3 compliance and unlimited moisture sensitivity classification, ensuring compatibility with modern manufacturing and environmental standards. The identical 16-SOIC package specification guarantees mechanical and electrical interchangeability on printed circuit boards without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the MC74HC160ADR2G replace the 74HC160D,653 in existing designs?

A: Yes. Both components are functionally identical decade counters with matching logic type, bit configuration, timing characteristics, and package specifications. Direct substitution is supported without circuit modifications.

Q: What is the significance of the different operating temperature ranges?

A: The 74HC160D,653 operates from -40°C to 125°C, while the MC74HC160ADR2G operates from -55°C to 125°C. The onsemi part provides extended low-temperature performance. For applications operating above -40°C, both parts are equivalent. For applications requiring operation below -40°C, the MC74HC160ADR2G is the appropriate selection.

Q: Are the package specifications identical?

A: Yes. Both components use the 16-SOIC (0.154", 3.90mm Width) surface mount package. Pin count, pitch, and physical dimensions are identical, enabling direct board-level substitution.

Q: Do both parts meet current compliance requirements?

A: Yes. Both the 74HC160D,653 and MC74HC160ADR2G are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity classification, meeting modern environmental and manufacturing standards.

Q: What is the count rate difference between these parts?

A: The 74HC160D,653 specifies a maximum count rate of 66 MHz, while the MC74HC160ADR2G specifies 35 MHz. For applications requiring operation above 35 MHz, the Nexperia part provides higher performance. For standard decade counter applications operating below 35 MHz, both parts are functionally equivalent.
