Key Parameters

Substitute Part Grouping Explanation

Substitution for the LFXP6C-3T144C is determined by the following critical parameters:

• Package compatibility: 144-LQFP form factor (20x20mm)
• I/O pin count: Minimum 100 pins required
• Logic element capacity: Minimum 6000 cells
• Surface mount technology
• Operating temperature range: 0°C to 85°C
• Moisture sensitivity level: MSL 3

Two substitute parts meet these criteria:

1. LFXP2-8E-5TN144C - Maintains identical I/O count (100 pins) and package format with enhanced logic capacity (8000 cells) and RAM (226304 bits). Operates at lower supply voltage (1.14V ~ 1.26V) with active product status and RoHS3 compliance.

2. LCMXO2-7000HC-4TG144C - Provides increased I/O capability (114 pins) and logic capacity (6864 cells) in the same 144-LQFP package. Operates at higher supply voltage range (2.375V ~ 3.465V) with active product status and RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

LFXP2-8E-5TN144C is the preferred substitute when:

• Identical I/O pin count (100) is required for direct PCB compatibility
• Lower supply voltage operation (1.14V ~ 1.26V) is specified in the design
• Enhanced logic capacity and RAM are beneficial for design migration
• Active product status and RoHS3 compliance are required for new designs

LCMXO2-7000HC-4TG144C is the preferred substitute when:

• Supply voltage range overlaps with the original part (2.375V ~ 3.465V upper range)
• Additional I/O pins (114 total) can be accommodated in the design
• Enhanced logic capacity and RAM support design requirements
• Active product status and RoHS3 compliance are required for new designs

Both substitutes maintain the 144-LQFP package format, MSL 3 rating, and 0°C to 85°C operating temperature range, ensuring mechanical and thermal compatibility with existing designs.

Frequently Asked Questions (FAQ)

Q: Can LFXP2-8E-5TN144C replace LFXP6C-3T144C in existing designs?

A: Yes, for designs where the supply voltage can be adjusted to 1.14V ~ 1.26V. The identical 100 I/O pin count and 144-LQFP package ensure PCB compatibility. The increased logic capacity (8000 vs 6000 cells) and RAM (226304 vs 73728 bits) provide design headroom.

Q: Can LCMXO2-7000HC-4TG144C replace LFXP6C-3T144C in existing designs?

A: Yes, for designs where the additional 14 I/O pins can be accommodated or left unconnected. The supply voltage range (2.375V ~ 3.465V) overlaps with the original part's upper range. The 144-LQFP package ensures mechanical compatibility.

Q: What is the primary difference between the two substitute parts?

A: LFXP2-8E-5TN144C maintains the original 100 I/O pin count but requires lower supply voltage (1.14V ~ 1.26V). LCMXO2-7000HC-4TG144C provides 114 I/O pins and operates at higher supply voltage (2.375V ~ 3.465V). Both are active products with RoHS3 compliance.

Q: Are all three parts in the same package?

A: Yes, all three parts use the 144-LQFP (20x20mm) surface mount package, ensuring identical PCB footprint and mounting requirements.

Q: What is the significance of the obsolete status for LFXP6C-3T144C?

A: Obsolete status indicates the part is no longer manufactured. Both substitute parts are active products, ensuring long-term availability and continued manufacturing support.

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

A: Yes, all three parts are rated MSL 3 (168 Hours), requiring identical handling and storage conditions.
