Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MM5453VX is determined by strict equivalence across the following critical parameters:

• Display Type & Configuration: Must support LCD with 7-segment + decimal point, alphanumeric, and bar graph capability
• Interface Protocol: Serial interface requirement
• Display Capacity: 4.5-digit support
• Supply Voltage Range: 3V to 10V operation
• Operating Temperature Range: -40°C to 85°C
• Package Specification: 44-LCC (J-Lead) / 44-PLCC (16.58x16.58) form factor
• Mounting Technology: Surface mount configuration

The MM5453VX/NOPB qualifies as a direct substitute based on identical electrical specifications, package geometry, and functional capability. The primary distinction lies in packaging format (Tape & Reel versus bulk) and product lifecycle status.

Parameter Comparison

Engineering Selection Recommendations

MM5453VX/NOPB is the direct functional equivalent for MM5453VX applications. Selection between these parts should be based on the following criteria:

Use MM5453VX/NOPB when:

• New production designs require RoHS3 compliance
• Supply chain access to Last Time Buy inventory is available
• Tape & Reel packaging format is compatible with assembly processes
• Moisture sensitivity level of 3 (168 hours) meets storage and handling requirements

Use MM5453VX when:

• Legacy system maintenance requires exact original part specification
• RoHS non-compliance is acceptable for the application
• Bulk packaging format is required
• Moisture sensitivity level of 2A (4 weeks) is specified

Both parts share identical electrical performance, display capability, and physical package dimensions, ensuring direct pin-for-pin and functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can MM5453VX/NOPB replace MM5453VX in existing designs?

A: Yes. Both parts are electrically and functionally identical across all critical parameters: display type, configuration, interface protocol, digit capacity, supply voltage range, operating temperature, and package geometry. The primary differences are product lifecycle status and regulatory compliance certifications.

Q: What is the significance of the "/NOPB" suffix?

A: The "/NOPB" designation indicates the part is supplied in Tape & Reel packaging format without lead (Pb) content, reflecting RoHS3 compliance. The base MM5453VX may be supplied in alternative packaging formats.

Q: Are there package compatibility concerns between these parts?

A: No. Both parts use identical 44-LCC (J-Lead) package geometry with 44-PLCC (16.58x16.58) supplier specifications. PCB footprints, solder pad layouts, and mounting procedures are identical.

Q: What is the impact of different RoHS compliance levels?

A: MM5453VX is RoHS non-compliant, while MM5453VX/NOPB is ROHS3 compliant. For applications subject to RoHS regulations or customer requirements, MM5453VX/NOPB is the appropriate selection. For legacy or non-regulated applications, either part is acceptable.

Q: How do moisture sensitivity levels differ between these parts?

A: MM5453VX has MSL 2A (4 weeks), while MM5453VX/NOPB has MSL 3 (168 hours). MSL 3 allows longer storage periods without baking. Selection depends on supply chain handling and storage duration requirements.

Q: Is MM5453VX/NOPB still available for procurement?

A: MM5453VX/NOPB is classified as Last Time Buy, indicating limited remaining inventory. MM5453VX is obsolete. Availability should be confirmed with authorized distributors before design commitment.
