Parameter Comparison

Engineering Selection Recommendations

Both the 3386V-1-203 and 72XR20KLF are active production components with identical electrical and mechanical specifications. Selection between these parts may be influenced by regulatory compliance requirements. The 3386V-1-203 is RoHS non-compliant and REACH Affected. The 72XR20KLF is ROHS3 Compliant and REACH Unaffected, making it suitable for applications subject to RoHS3 or REACH regulatory frameworks. Both components carry the same ECCN (EAR99) and HTSUS classification (8533.40.8050).

Frequently Asked Questions (FAQ)

Q: Can the 72XR20KLF replace the 3386V-1-203 in existing designs?

A: Yes. The 72XR20KLF meets all electrical and mechanical specifications of the 3386V-1-203, including resistance, power rating, tolerance, temperature coefficient, adjustment type, resistive material, mounting configuration, termination style, and physical dimensions. Direct substitution is electrically and mechanically compatible.

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

A: The primary difference is regulatory compliance status. The 72XR20KLF is ROHS3 Compliant and REACH Unaffected, while the 3386V-1-203 is RoHS non-compliant and REACH Affected. Both parts are functionally equivalent.

Q: Are there packaging differences between these parts?

A: Yes. The 3386V-1-203 is supplied in Tube packaging, while the 72XR20KLF is supplied in Bulk packaging. This distinction affects handling and storage but does not impact electrical or mechanical performance.

Q: What parameters must remain constant for substitution?

A: The following parameters must be identical: 20 kOhms resistance, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, 1 turn, side adjustment, cermet resistive material, through-hole mounting, PC pin termination, and 0.375" x 0.375" (9.53mm x 9.53mm) square dimensions.
