Substitute Part Grouping Explanation

Substitute parts for the 3314S-2-502G are qualified based on the following matching criteria:

• Resistance value: 5 kOhms
• Power rating: 0.25W (1/4W)
• Tolerance: ±20%
• Temperature coefficient: ±100ppm/°C
• Number of turns: 1 turn
• Resistive material: Cermet
• Mounting type: Surface Mount
• Termination style: J Lead
• Package dimensions: Rectangular - 0.197" x 0.177" Face (5.00mm x 4.50mm)
• Packaging format: Tape & Reel (TR)

The primary distinction between the main part and identified substitutes is the adjustment type: the 3314S-2-502G features side adjustment, while substitute parts 23AR5KLFTR and ST-4ETA502 feature top adjustment. Both adjustment types are compatible with the same PCB footprint and electrical performance requirements.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active production status with full compliance certifications. The 3314S-2-502G and ST-4ETA502 both carry ROHS3 compliance, while the 23AR5KLFTR carries standard RoHS compliance. All parts are REACH unaffected and classified under ECCN EAR99.

Selection between these parts should be based on adjustment accessibility requirements for the application. The 3314S-2-502G provides side adjustment access, while 23AR5KLFTR and ST-4ETA502 provide top adjustment access. Inventory availability may also influence selection, with ST-4ETA502 currently showing the highest stock level at 32,030 pieces.

Frequently Asked Questions (FAQ)

Q: Can the 23AR5KLFTR or ST-4ETA502 be used as direct replacements for the 3314S-2-502G?

A: Yes, both parts are electrically and mechanically compatible. The primary difference is adjustment type: side adjustment versus top adjustment. PCB footprint compatibility is maintained across all three parts.

Q: What is the significance of the adjustment type difference?

A: Adjustment type determines the physical access point for potentiometer tuning. Side adjustment requires access from the component side edge, while top adjustment requires access from the component top surface. The choice depends on PCB layout and accessibility requirements in the final assembly.

Q: Are there compliance differences between these parts?

A: The 3314S-2-502G and ST-4ETA502 are ROHS3 compliant, while the 23AR5KLFTR is RoHS compliant. All three parts are REACH unaffected and carry the same MSL rating of 1 (Unlimited).

Q: Do all parts share the same package dimensions?

A: Yes, all three parts have identical rectangular package dimensions of 0.197" x 0.177" face (5.00mm x 4.50mm) and are supplied in Tape & Reel packaging format.

Q: What electrical parameters must match for substitution?

A: Resistance value, power rating, tolerance, temperature coefficient, number of turns, and resistive material must all match. All three parts share identical specifications in these categories: 5 kOhms, 0.25W, ±20% tolerance, ±100ppm/°C temperature coefficient, 1 turn, and cermet material.
