Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MK2703S is determined by the following critical parameters:

• Frequency specification: Maximum operating frequency of 27MHz
• Input/Output configuration: Clock or Crystal input with CMOS output
• Circuit count: Single circuit (1)
• Input:Output ratio: 2:2 configuration
• Supply voltage range: 3.13V ~ 5.5V compatibility
• Operating temperature range: 0°C ~ 70°C
• Package type: 8-SOIC (0.154", 3.90mm Width) surface mount
• PLL capability: Integrated PLL with bypass functionality

The MK2703SLF meets all substitution criteria as a direct equivalent from the same manufacturer, maintaining identical electrical specifications and physical packaging.

Parameter Comparison

Engineering Selection Recommendations

The MK2703SLF is a direct functional equivalent to the MK2703S. Both components are manufactured by Renesas Electronics Corporation and share identical electrical and mechanical specifications. The MK2703SLF maintains the same 27MHz maximum frequency, supply voltage range (3.13V ~ 5.5V), operating temperature range (0°C ~ 70°C), and 8-SOIC package configuration.

Both parts carry obsolete product status. Selection between these parts should be based on current inventory availability and lead time requirements, as they are electrically and mechanically interchangeable.

Frequently Asked Questions (FAQ)

Q: Can the MK2703SLF be used as a direct replacement for the MK2703S?

A: Yes. The MK2703SLF is a direct equivalent. Both parts share identical electrical specifications, including 27MHz maximum frequency, 3.13V ~ 5.5V supply voltage range, CMOS output, and 8-SOIC packaging. No circuit modifications are required.

Q: Are there any differences in the package footprint between MK2703S and MK2703SLF?

A: No. Both parts use the same 8-SOIC (0.154", 3.90mm Width) surface mount package. PCB layouts and footprints are identical.

Q: What is the significance of the "SLF" suffix in the MK2703SLF part number?

A: The suffix typically indicates a specific lead finish or packaging variant from the manufacturer. However, the electrical and mechanical specifications remain identical to the MK2703S.

Q: Why are both parts listed as obsolete?

A: Both the MK2703S and MK2703SLF are obsolete products from Renesas Electronics Corporation. This status indicates that the manufacturer has discontinued active production and support. Existing inventory from authorized distributors may still be available.

Q: What input types does this PLL Clock Synthesizer support?

A: The MK2703S and MK2703SLF accept either clock or crystal inputs, providing flexibility in clock source selection for different application requirements.

Q: Is the PLL bypass function available on both parts?

A: Yes. Both the MK2703S and MK2703SLF include integrated PLL with bypass capability, allowing the device to operate in bypass mode when PLL synthesis is not required.
