Equivalent & Substitute Parts for 85322AMLFT

Part Overview

The 85322AMLFT is a mixed signal translator manufactured by Renesas Electronics Corporation, designed to convert unidirectional signals from LVCMOS/LVTTL input levels to LVPECL differential output levels. This 8-SOIC surface mount device integrates one circuit with two channels per circuit, providing signal translation functionality for logic-level applications.

The 85322AMLFT carries an obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for systems utilizing this translator.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 85322AMLFT are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Translator Type: Mixed Signal
• Channel Type: Unidirectional
• Number of Circuits: 1
• Channels per Circuit: 2
• Input Signal Compatibility: LVCMOS, LVTTL
• Output Signal: LVPECL
• Output Type: Differential
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

The substitute parts identified (MC100EPT22DR2G and MC100LVELT22DR2G) satisfy all critical electrical and mechanical parameters. Both are manufactured by onsemi and maintain identical package specifications, signal characteristics, and compliance certifications. The primary distinction between substitutes lies in operating temperature range and packaging format, which do not affect functional equivalence for the core translation function.

Parameter Comparison

Engineering Selection Recommendations

Both MC100EPT22DR2G and MC100LVELT22DR2G are functionally equivalent substitutes for the obsolete 85322AMLFT. Selection between the two substitutes should be based on the following factors:

MC100EPT22DR2G (onsemi 100EPT Series):

• Active product status with established supply chain availability
• Operating temperature range: -40°C ~ 85°C
• Packaging: Tape & Reel (TR)
• Suitable for applications requiring extended temperature operation beyond the original 0°C ~ 70°C specification

MC100LVELT22DR2G (onsemi 100LVELT Series):

• Active product status with established supply chain availability
• Operating temperature range: -40°C ~ 85°C
• Packaging: Cut Tape (CT) & Digi-Reel®
• Suitable for applications requiring extended temperature operation beyond the original 0°C ~ 70°C specification

Both substitutes maintain full compliance with ROHS3 and REACH requirements. The extended operating temperature range of both substitutes (-40°C ~ 85°C versus the original 0°C ~ 70°C) provides additional operational margin. Selection between the two may be determined by packaging format preference and supplier availability.

Frequently Asked Questions (FAQ)

Q: Can MC100EPT22DR2G and MC100LVELT22DR2G be used interchangeably with 85322AMLFT?

A: Yes. Both parts are functionally equivalent substitutes. They share identical electrical characteristics for signal translation (LVCMOS/LVTTL input to LVPECL differential output), circuit configuration (1 circuit, 2 channels), and package specifications (8-SOIC surface mount). Both are ROHS3 compliant and carry MSL 1 rating.

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

A: The primary differences are manufacturer series designation (100EPT versus 100LVELT) and packaging format (Tape & Reel versus Cut Tape & Digi-Reel). Both operate across -40°C ~ 85°C, which exceeds the original part's 0°C ~ 70°C range. Electrical performance and package dimensions are identical.

Q: Is the extended operating temperature range of the substitutes a concern?

A: No. The extended temperature range (-40°C ~ 85°C) of both substitutes encompasses the original specification (0°C ~ 70°C). This provides additional operational margin and does not introduce compatibility issues.

Q: Are the substitute parts pin-compatible with the 85322AMLFT?

A: Yes. All three parts use the 8-SOIC package with identical pinout and signal assignments. Direct board-level substitution is supported without layout modifications.

Q: What is the compliance status of the substitute parts?

A: Both MC100EPT22DR2G and MC100LVELT22DR2G are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating, matching the original part's compliance profile.

Q: Which substitute should be selected for new designs?

A: Both substitutes are suitable for new designs. Selection should be based on packaging preference (Tape & Reel versus Cut Tape & Digi-Reel) and supplier availability. Both are active products with established supply chains.
