Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MT8980DP1 are identified based on the following critical parameters that determine functional and mechanical compatibility:

Primary Compatibility Criteria:

• Package / Case: 44-LCC (J-Lead) with 44-PLCC (16.59x16.59) footprint
• Mounting Type: Surface Mount
• Number of Circuits: 1
• Operating Temperature Range: -40°C to 85°C
• Moisture Sensitivity Level: 3 (168 Hours)

Voltage Supply Compatibility: The MT8980DP1 operates at 4.75V to 5.25V. Substitute parts are grouped into two categories based on supply voltage specifications:

Group 1 - Direct Voltage Match (4.75V ~ 5.25V):

• 728980J (Renesas Electronics Corporation)
• 728980J8 (Renesas Electronics Corporation)

Group 2 - Manufacturer Recommended (3V ~ 3.6V):

• 72V8985J (Renesas Electronics Corporation)
• 72V8985J8 (Renesas Electronics Corporation)

All substitute parts are multiplexer ICs with 1 x 8:8 circuit configuration, single supply voltage source, and identical package specifications. Group 1 parts maintain the original voltage specification, while Group 2 parts represent manufacturer-recommended alternatives with lower voltage operation.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Voltage-Compatible Systems):

The 728980J and 728980J8 from Renesas Electronics Corporation are direct substitutes for the MT8980DP1 in systems operating at 4.75V to 5.25V. Both parts maintain identical supply voltage specifications, operating temperature range, and package configuration. These parts are currently in active production status with inventory availability (745 Pcs and 1033 Pcs respectively). Note that these alternatives are RoHS non-compliant, whereas the original MT8980DP1 is ROHS3 compliant. This distinction is relevant for applications subject to RoHS regulations.

For Manufacturer-Recommended Alternatives:

The 72V8985J and 72V8985J8 are manufacturer-recommended alternatives from Renesas Electronics Corporation. These parts operate at a lower voltage range of 3V to 3.6V and are designated as active products with current inventory (1104 Pcs and 651 Pcs respectively). Selection of these parts requires system voltage compatibility verification, as they operate outside the original 4.75V to 5.25V specification. Both parts maintain the same package footprint, operating temperature range, and MSL rating as the original component.

Compliance Considerations:

All substitute parts share identical REACH status (REACH Unaffected) and ECCN classification (EAR99) with the original MT8980DP1. RoHS compliance differs between the original part (ROHS3 compliant) and all substitute options (RoHS non-compliant). System designers must evaluate regulatory requirements for their specific application.

Frequently Asked Questions (FAQ)

Q: Can the 728980J or 728980J8 be used as a direct replacement for the MT8980DP1?

A: Yes, both 728980J and 728980J8 are direct substitutes. They maintain the same supply voltage range (4.75V ~ 5.25V), operating temperature (-40°C ~ 85°C), package configuration (44-PLCC 16.59x16.59), and circuit count (1). Both are currently in active production with available inventory.

Q: What is the difference between 728980J and 728980J8?

A: Both parts share identical electrical specifications and package configuration. The designation difference (J vs. J8) reflects manufacturer part numbering conventions. Electrical and mechanical compatibility with the MT8980DP1 is equivalent for both variants.

Q: When should the 72V8985J or 72V8985J8 be selected instead of the 728980J series?

A: The 72V8985J and 72V8985J8 are manufacturer-recommended alternatives and operate at 3V to 3.6V supply voltage. These parts should be selected only when system voltage specifications support the lower operating range. The original MT8980DP1 operates at 4.75V to 5.25V, so voltage compatibility must be confirmed before substitution.

Q: Are all substitute parts compatible with the same PCB footprint as the MT8980DP1?

A: Yes. All substitute parts use the 44-PLCC (16.59x16.59) package with 44-LCC (J-Lead) case configuration, ensuring mechanical and electrical compatibility with existing PCB layouts designed for the MT8980DP1.

Q: What is the impact of RoHS compliance differences?

A: The MT8980DP1 is ROHS3 compliant, while all substitute parts are RoHS non-compliant. Applications subject to RoHS regulations must account for this difference. Systems without RoHS requirements are unaffected by this distinction.

Q: Do all parts share the same moisture sensitivity level?

A: Yes. The MT8980DP1 and all substitute parts (728980J, 728980J8, 72V8985J, 72V8985J8) are rated at MSL 3 (168 Hours), indicating identical moisture handling and storage requirements.

Q: What inventory status should influence part selection?

A: All substitute parts are in active production with current inventory availability. The 728980J8 has the highest inventory (1033 Pcs), followed by 72V8985J (1104 Pcs), 72V8985J8 (651 Pcs), and 728980J (745 Pcs). Inventory levels may influence procurement timelines but do not affect technical compatibility.
