Parameter Comparison

Engineering Selection Recommendations

Both the 3386J-1-102 and 72XR1KLF are electrically and mechanically equivalent for circuit applications requiring 1 kOhm, 0.5W trimmer potentiometers with side adjustment and PC pin termination.

The 72XR1KLF offers compliance advantages: it is ROHS3 compliant and REACH unaffected, whereas the 3386J-1-102 is RoHS non-compliant and REACH affected. Selection between these parts should be based on end-product compliance requirements and regional regulatory obligations.

Both parts carry active product status and equivalent ECCN and HTSUS classifications.

Frequently Asked Questions (FAQ)

Q: Can the 72XR1KLF directly replace the 3386J-1-102 in existing designs?

A: Yes. The 72XR1KLF meets all electrical specifications (1 kOhm resistance, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient) and mechanical requirements (through-hole mounting, PC pin termination, side adjustment, identical physical dimensions). No circuit modifications are required.

Q: What is the difference in packaging between these parts?

A: The 3386J-1-102 is supplied in tube packaging, while the 72XR1KLF is supplied in bulk packaging. This affects handling and storage but does not impact electrical or mechanical performance.

Q: Why would I choose the 72XR1KLF over the 3386J-1-102?

A: The 72XR1KLF is ROHS3 compliant and REACH unaffected, making it suitable for applications subject to these regulatory frameworks. The 3386J-1-102 is RoHS non-compliant and REACH affected, which may restrict its use in certain markets or end applications.

Q: Are there any performance differences between these trimmer potentiometers?

A: No. Both parts share identical electrical characteristics, temperature performance, and mechanical specifications. Performance in circuit operation is equivalent.

Q: What inventory levels are available?

A: The 3386J-1-102 has 832 pieces in stock. The 72XR1KLF has 2606 pieces in stock, providing greater availability for high-volume requirements.
