Substitute Part Grouping Explanation

The MC100EPT23DTG from onsemi qualifies as a functional equivalent based on the following critical parameters:

Matching Electrical Characteristics:

• Translator Type: Mixed Signal (identical function)
• Channel Type: Unidirectional (identical signal direction)
• Input Signal: LVPECL (primary input standard supported)
• Output Signal: LVTTL (primary output standard supported)
• Operating Temperature Range: -40°C ~ 85°C (identical thermal specification)

Matching Physical Characteristics:

• Package / Case: 8-TSSOP, 8-MSOP (0.118", 3.00mm Width) (pin-compatible footprint)
• Mounting Type: Surface Mount (identical assembly method)

Compliance Alignment:

• RoHS Status: ROHS3 Compliant (equivalent environmental standard)
• REACH Status: REACH Unaffected (equivalent regulatory status)
• ECCN: EAR99 (identical export classification)

The MC100EPT23DTG maintains active product status with established supply availability, making it suitable for replacement in applications currently using the obsolete SY10EPT23LKG.

Parameter Comparison

Engineering Selection Recommendations

The MC100EPT23DTG is the appropriate substitute for the obsolete SY10EPT23LKG based on the following engineering criteria:

Product Lifecycle Status: The SY10EPT23LKG is classified as obsolete, creating supply chain risk. The MC100EPT23DTG maintains active product status with documented inventory availability, ensuring long-term procurement viability.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying current environmental and regulatory requirements. Both carry identical ECCN and HTSUS classifications, maintaining export and tariff consistency.

Electrical Compatibility: The MC100EPT23DTG supports LVPECL input and LVTTL output as primary signal standards, directly matching the SY10EPT23LKG functional requirements. The substitute's additional input support (CML, LVDS) and output support (LVCMOS) provides design flexibility without compromising core functionality.

Physical Compatibility: Identical package designation (8-TSSOP, 8-MSOP) and mounting type ensure direct PCB footprint compatibility without layout modification.

Thermal Specification: Matching operating temperature range (-40°C to 85°C) maintains thermal performance equivalence across industrial applications.

Frequently Asked Questions (FAQ)

Q: Can the MC100EPT23DTG directly replace the SY10EPT23LKG without PCB modifications?

A: Yes. Both parts use the 8-TSSOP, 8-MSOP package with identical 0.118" width and 3.00mm pitch, ensuring pin-compatible footprints. No PCB layout changes are required.

Q: What is the primary reason for substitution?

A: The SY10EPT23LKG is obsolete. The MC100EPT23DTG is an active product with established supply channels, eliminating procurement risk.

Q: Are the signal conversion specifications identical?

A: Both parts perform unidirectional mixed signal translation from LVPECL to LVTTL. The MC100EPT23DTG additionally supports CML and LVDS inputs, and LVCMOS outputs, providing expanded compatibility while maintaining core LVPECL-to-LVTTL conversion.

Q: Do both parts meet the same environmental standards?

A: Yes. Both are ROHS3 compliant, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Q: What is the difference in Moisture Sensitivity Level (MSL)?

A: The SY10EPT23LKG has MSL 1 (unlimited shelf life), while the MC100EPT23DTG has MSL 3 (168-hour limit). MSL 3 requires controlled storage conditions but is standard for active production components. Verify storage and handling procedures align with your supply chain practices.

Q: Is the operating temperature range the same?

A: Yes. Both parts operate across -40°C to 85°C (TA), maintaining thermal equivalence for industrial applications.

Q: Can I use the MC100EPT23DTG in new designs?

A: Yes. As an active product with established supply availability, the MC100EPT23DTG is suitable for both replacement applications and new design implementations.
