LM567CM Equivalent & Substitute Parts Engineering Reference

Part Overview

The LM567CM by Texas Instruments is a telecom interface IC, specifically designed as a tone decoder and supplied in an 8-SOIC surface-mount package. The LM567CM is classified as obsolete, necessitating the identification of substitute components for continued design support or production use. Substitution is required to maintain the intended function, compatibility, and compliance level within application circuits.

Key Parameters

Substitute Part Grouping Explanation

Substitute selection for LM567CM is strictly governed by the following explicit parameters: manufacturer part number, package type (8-SOIC surface-mount), function (tone decoder), electrical ratings (4.75V ~ 9V supply voltage, 12mA supply current, 1.1 W power), operating temperature range (0°C ~ 70°C), circuit quantity (1), and compliance attributes (RoHS, REACH, MSL). Only parts matching all provided fields are considered suitable substitutes in this product category.

Parameter Comparison

Engineering Selection Recommendations

The LM567CM is obsolete and RoHS non-compliant. The substitute LM567CM/NOPB provides active product status and ROHS3 compliance, with matching electrical, mechanical, package, and function parameters. Both parts are REACH unaffected and share an MSL value of 1 (Unlimited). The substitute LM567CM/NOPB is suitable for designs requiring current environmental compliance and uninterrupted availability within the 8-SOIC telecom interface IC product category.

Frequently Asked Questions (FAQ)

Q1: What are the key parameters for selecting a substitute for LM567CM?
A1: Key parameters include manufacturer part number, function (tone decoder), number of circuits (1), voltage and current supply ratings (4.75V ~ 9V, 12mA), power rating (1.1 W), operating temperature (0°C ~ 70°C), mounting type (surface mount), package/case (8-SOIC, 0.154", 3.90mm width), RoHS and REACH status, and product status.

Q2: Is LM567CM/NOPB compatible in terms of form factor and electrical characteristics?
A2: LM567CM/NOPB matches the 8-SOIC package, supply voltage/current requirements, function, number of circuits, and operating temperature range.

Q3: What compliance differences exist between LM567CM and LM567CM/NOPB?
A3: LM567CM is RoHS non-compliant, while LM567CM/NOPB is ROHS3 Compliant. Both are REACH unaffected and have matching MSL ratings.

Q4: Why is it necessary to use substitute parts for LM567CM?
A4: LM567CM is obsolete; substitute selection maintains function, compatibility, and compliance within systems requiring a telecom interface IC tone decoder.

Q5: Are mounting and package details identical for substitute selection?
A5: Both LM567CM and LM567CM/NOPB utilize surface mount technology and share identical 8-SOIC package specifications.
