Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCP4462T-503E/ST is determined by strict equivalence across all electrical and mechanical parameters. The primary differentiator between the main part and identified substitutes is the packaging configuration (Tape & Reel versus Tube), which does not affect functional performance or circuit compatibility.

The following parameters must remain identical for valid substitution:

• Resistance value: 50kΩ
• Number of circuits: 4
• Number of taps: 257
• Interface protocol: I2C
• Memory type: Non-Volatile
• Supply voltage range: 1.8V ~ 5.5V
• Package type: 14-TSSOP
• Physical dimensions: 0.173" × 4.40mm width
• Operating temperature range: -40°C ~ 125°C
• All electrical characteristics and compliance certifications

Parameter Comparison

Engineering Selection Recommendations

Both MCP4462T-503E/ST and MCP4462-503E/ST are active production components with identical electrical specifications and full regulatory compliance. Selection between these parts is determined by supply chain requirements and packaging logistics rather than functional performance.

The Tape & Reel (TR) packaging of MCP4462T-503E/ST is optimized for high-volume automated assembly operations. The Tube packaging of MCP4462-503E/ST is suitable for lower-volume applications or manual assembly processes. Both configurations maintain ROHS3 compliance, REACH unaffected status, and MSL Level 1 (unlimited moisture sensitivity).

Component selection should be based on procurement availability, assembly equipment compatibility, and inventory management requirements. No functional or performance differences exist between the two packaging configurations.

Frequently Asked Questions (FAQ)

Q: Can MCP4462-503E/ST (Tube) be used as a direct replacement for MCP4462T-503E/ST (Tape & Reel)?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format. Substitution is valid for any application where the original part is specified, provided assembly equipment can accommodate the Tube packaging format.

Q: Are there any electrical performance differences between the two packaging options?

A: No. Both parts share identical electrical characteristics, including resistance value, tap count, interface protocol, supply voltage range, operating temperature range, and all other functional parameters.

Q: What is the significance of the packaging difference?

A: Packaging affects supply chain logistics and assembly processes. Tape & Reel packaging is designed for automated pick-and-place assembly systems. Tube packaging is typically used for manual assembly or lower-volume production runs. The choice depends on manufacturing requirements, not circuit performance.

Q: Are both parts RoHS3 compliant?

A: Yes. Both MCP4462T-503E/ST and MCP4462-503E/ST are ROHS3 compliant with REACH unaffected status.

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

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