Equivalent & Substitute Parts Reference for Vishay Dale CMF55170R00FKBF

Part Overview

The Vishay Dale CMF55170R00FKBF is a 170 Ohms ±1% 0.5W axial metal film resistor featuring flame retardant coating, moisture resistance, and safety attributes, packaged in bulk. It is classified as obsolete and is listed as RoHS non-compliant and REACH affected. As this component is no longer active, identifying parametric equivalents is necessary for maintaining design continuity and ensuring compliance with supply chain requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute selection is strictly based on matching electrical and mechanical parameters: resistance (170 Ohms), tolerance (±1%), power rating (0.5W, 1/2W), composition (metal film), flame retardant coating, moisture resistance, safety features, temperature coefficient (±100ppm/°C), operating temperature (-55°C ~ 175°C), axial package, physical dimensions, and number of terminations. Regulatory compliance (RoHS, REACH status) and product availability (active status) are also included.

Parameter Comparison

Engineering Selection Recommendations

The main part CMF55170R00FKBF is obsolete and not RoHS compliant; the parameter-equivalent substitute CMF55170R00FKEK is active and ROHS3 compliant. For applications requiring compliance with current RoHS regulations or where active supply status is required, CMF55170R00FKEK is a suitable selection.

Frequently Asked Questions (FAQ)

Q1: What parameters must match for substituting axial metal film resistors in this category?
Electrical characteristics (resistance, tolerance, power rating), physical dimensions, temperature coefficient, and mechanical packaging must be identical.

Q2: Are CMF55170R00FKEK and CMF55170R00FKBF compatible in the same PCB footprint?
Both utilize identical axial packages with matching dimensions and terminations; physical compatibility is provided.

Q3: Does RoHS status affect substitution in regulated regions?
In regions enforcing RoHS compliance, only parts listed as compliant (e.g., CMF55170R00FKEK) can be selected to meet regulatory requirements.

Q4: Is there any functional difference between the main part and its substitute?
Based strictly on supplied parameters, no differences exist in core function, features, or performance.

Q5: Can the substitute part be used in all existing designs using CMF55170R00FKBF?
With all key parameters and package details matching, substitution is technically supported where compliance and active status are required.
