Parameter Comparison

Engineering Selection Recommendations

Precision Electronics RV6NAYSD103A is suitable for direct substitution where termination method can accommodate solder lug connection. This part maintains identical electrical specifications and mechanical dimensions to the Honeywell 392C310K. The carbon resistive material provides equivalent performance within the specified tolerance range. Active product status ensures long-term availability. ROHS3 compliance exceeds the original RoHS requirement.

Bourns 3862C-286-103AL is suitable for applications where increased power dissipation capacity is beneficial. This part provides 1W power rating compared to the 0.5W/1/2W rating of the original component, with identical electrical and mechanical specifications. PC pin termination matches the original configuration. Body diameter is 0.010" smaller (0.500" versus 0.510"), which remains within acceptable mechanical tolerance for panel mount applications. Active product status and ROHS3 compliance ensure supply continuity. Temperature coefficient specification (±150ppm/°C) is provided for this substitute.

Both substitutes are electrically and mechanically compatible with the Honeywell 392C310K within the specified parameter allowances.

Frequently Asked Questions (FAQ)

Q: Can the Precision Electronics RV6NAYSD103A replace the Honeywell 392C310K directly?

A: Yes, the RV6NAYSD103A meets all mandatory electrical and mechanical parameters. The primary difference is termination style: solder lug versus PC pins. Circuit board layout and connection method must accommodate solder lug termination.

Q: What is the difference between conductive plastic, carbon, and cermet resistive materials?

A: These are the resistive materials used in the three potentiometers. All three materials are specified in the provided data and all three parts meet the electrical requirements for 10k Ohm ±10% tolerance at 0.5W or higher power rating. Material selection depends on application-specific requirements not specified in the substitution parameters.

Q: Does the Bourns 3862C-286-103AL body diameter difference affect mechanical fit?

A: The Bourns part body diameter is 0.500" compared to 0.510" for the original. This 0.010" difference is within typical mechanical tolerance for panel mount potentiometers with 1/4-32 bushing thread. Verify clearance in the specific panel mounting application.

Q: Are both substitute parts currently available?

A: Yes. The Precision Electronics RV6NAYSD103A has 2032 pieces in stock. The Bourns 3862C-286-103AL has 1116 pieces in stock. Both are active products with confirmed availability.

Q: What is the significance of the higher power rating on the Bourns part?

A: The Bourns 3862C-286-103AL is rated for 1W versus 0.5W/1/2W on the original. Higher power rating indicates greater heat dissipation capability. This is an allowable variation that does not restrict substitution; it provides additional margin for applications with higher power requirements.

Q: How do packaging differences affect part selection?

A: The Honeywell 392C310K packaging is not specified. The Precision Electronics RV6NAYSD103A is supplied in bulk packaging. The Bourns 3862C-286-103AL is supplied in tray packaging. Packaging affects handling, storage, and procurement logistics but does not affect electrical or mechanical compatibility.

Q: Are there compliance differences between the three parts?

A: The Honeywell 392C310K is RoHS Compliant. Both substitutes are ROHS3 Compliant, which represents a more recent and stringent standard. The Bourns part is REACH Affected; the Precision Electronics part is REACH Unaffected. Verify REACH compliance requirements for your specific application and end market.
