Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LTC2850MPMS8 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Identical protocol support (RS422 and RS485)
• Matching transceiver configuration (1/1 half-duplex)
• Equivalent data rate specification (20 Mbps)
• Identical supply voltage range (3V to 3.6V)
• Matching receiver hysteresis (25 mV)
• Identical operating temperature range (-55°C to 125°C)

Mechanical Equivalence Requirements:

• Identical package type (8-TSSOP/8-MSOP)
• Matching package dimensions (0.118", 3.00mm Width)
• Surface mount mounting type

Compliance Equivalence Requirements:

• RoHS3 compliance status
• REACH unaffected classification
• Identical moisture sensitivity level (MSL 1)

Parts meeting all three equivalence categories are classified as parametric equivalents and direct substitutes. Packaging format variations (such as tube versus alternative packaging) do not affect electrical or mechanical compatibility and represent valid substitution options.

Parameter Comparison

Engineering Selection Recommendations

The LTC2850MPMS8#PBF is a direct parametric equivalent to the LTC2850MPMS8. Both parts are manufactured by Analog Devices Inc. and maintain Active product status with identical electrical specifications, mechanical dimensions, and compliance certifications.

The primary distinction between these parts is packaging format. The LTC2850MPMS8#PBF is supplied in tube packaging, while the LTC2850MPMS8 may be supplied in alternative packaging configurations. This packaging difference does not affect component functionality, performance, or circuit board integration.

Selection between these equivalent parts should be based on:
