Substitute Part Grouping Explanation

The Bourns 3310C-001-502L qualifies as a substitute for the 3360C-1-502LF based on the following critical parameters:

Electrical equivalence is established through matching resistance value (5k Ohm), power rating (0.25W), tolerance (±20%), temperature coefficient (±1000ppm/°C), taper (Linear), number of gangs (1), and resistive material (Conductive Plastic).

Mechanical compatibility is confirmed through identical termination style (PC Pins), adjustment type (Side Adjustment), bushing thread (1/4-32), and mounting type (Panel Mount). Both components feature slotted actuators with identical actuator length (0.500" / 12.70mm).

Regulatory compliance is maintained, with both parts meeting ROHS3 requirements and sharing the same ECCN (EAR99) and HTSUS classification (8533.40.8070).

Engineering Selection Recommendations

Both the 3360C-1-502LF and 3310C-001-502L are actively manufactured products with ROHS3 compliance and identical regulatory classifications. Selection between these components should be based on mechanical fit requirements within the application enclosure.

The 3360C-1-502LF features a compact body footprint (6.70mm x 6.40mm) with a smaller actuator diameter (2.36mm) and 310° rotation range. This configuration is suitable for space-constrained applications.

The 3310C-001-502L provides a larger body footprint (9.53mm x 9.53mm) with a larger actuator diameter (3.18mm) and 300° rotation range. The sealed feature designation indicates enhanced environmental protection. This configuration is suitable for applications requiring robust mechanical handling or enhanced moisture resistance.

Both parts maintain identical electrical performance and regulatory compliance, making substitution viable when mechanical constraints permit the dimensional differences.

Frequently Asked Questions (FAQ)

Q: Can the 3310C-001-502L directly replace the 3360C-1-502LF in existing designs?

A: Direct electrical substitution is possible due to matching resistance, power rating, tolerance, taper, and termination specifications. However, mechanical fit must be verified. The 3310C-001-502L has a larger body (9.53mm vs 6.70mm) and larger actuator diameter (3.18mm vs 2.36mm), requiring confirmation that panel cutouts and mechanical clearances accommodate these dimensions.

Q: What are the key differences between these two potentiometers?

A: The primary differences are mechanical: body size, actuator diameter, and rotation range. The 3310C-001-502L is larger with a 300° rotation versus the 3360C-1-502LF's 310° rotation. The 3310C-001-502L includes a sealed feature. All electrical parameters remain identical.

Q: Are both parts RoHS compliant?

A: Yes, both the 3360C-1-502LF and 3310C-001-502L are ROHS3 compliant and share identical ECCN (EAR99) and HTSUS classifications.

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

A: The 3360C-1-502LF is supplied in Tray packaging, while the 3310C-001-502L is supplied in Bulk packaging. This affects handling and storage but does not impact component functionality.

Q: Does the rotation angle difference (310° vs 300°) affect circuit performance?

A: The 10° difference in mechanical rotation range does not affect electrical performance or resistance accuracy. Selection depends on application requirements for adjustment range and mechanical design constraints.
