Substitute Part Grouping Explanation

Substitution of the MK2705S is determined by strict equivalence across the following critical parameters:

  • Frequency Output: 24.576MHz (exact match required)
  • Supply Voltage Range: 3V ~ 3.6V (exact match required)
  • Operating Temperature Range: 0°C ~ 70°C (exact match required)
  • Package Type: 8-SOIC surface mount (exact match required)
  • Functional Purpose: Audio and MPEG clock synthesis with PLL capability
  • Input/Output Configuration: Single clock output from crystal or clock input with 1:1 ratio

The MK2705SLF is a direct functional equivalent of the MK2705S, sharing identical electrical specifications and package configuration. The primary distinction is packaging format (tube versus bulk) and RoHS compliance status.

Engineering Selection Recommendations

The MK2705SLF serves as the direct substitute for the MK2705S. Both parts are classified as obsolete and share identical electrical and mechanical specifications. The MK2705SLF offers improved compliance status, meeting ROHS3 requirements, whereas the MK2705S is RoHS non-compliant. For new designs or systems requiring regulatory compliance, the MK2705SLF is the appropriate selection. For legacy system maintenance where RoHS compliance is not mandated, either part provides equivalent functionality.

Both parts maintain REACH Unaffected status and carry the same ECCN and HTSUS classifications. Packaging format differs (tube for MK2705SLF versus unspecified for MK2705S), which may influence procurement logistics but does not affect electrical performance or PCB integration.

Frequently Asked Questions (FAQ)

Q: Can the MK2705SLF be used as a direct replacement for the MK2705S?

A: Yes. The MK2705SLF is electrically and mechanically identical to the MK2705S. Both devices generate 24.576MHz clock output, operate at 3V to 3.6V supply voltage, and are packaged in 8-SOIC surface mount configuration. No circuit modifications are required for substitution.

Q: What is the difference between MK2705S and MK2705SLF?

A: The primary differences are packaging format (tube for MK2705SLF) and RoHS compliance status. The MK2705SLF meets ROHS3 requirements, while the MK2705S is RoHS non-compliant. All electrical and functional specifications are identical.

Q: Are both parts still available for procurement?

A: Both the MK2705S and MK2705SLF are classified as obsolete products. Availability is limited to existing inventory. The MK2705S has 746 pieces in stock, while the MK2705SLF has 695 pieces available.

Q: What are the critical parameters for substitution?

A: Substitution is valid only when the following parameters match exactly: 24.576MHz frequency output, 3V to 3.6V supply voltage range, 0°C to 70°C operating temperature, 8-SOIC package type, and single clock output configuration with PLL capability.

Q: Can these parts be used in applications other than audio and MPEG?

A: These devices are specifically designed for audio and MPEG clock synthesis. Use in other applications requires verification that the 24.576MHz output frequency and electrical characteristics meet the application requirements.

Q: What is the moisture sensitivity level for these parts?

A: Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
