Substitute Part Grouping Explanation

Substitute parts for the 3313J-1-502G are qualified based on electrical and mechanical parameter alignment. The critical parameters determining substitution eligibility are: resistance value (5 kOhms), power rating (0.125W), tolerance (±20%), temperature coefficient (±100ppm/°C), number of turns (1), adjustment type (top adjustment), resistive material (cermet), mounting type (surface mount), termination style (J lead), and packaging format (Tape & Reel).

Two substitute parts meet these criteria:

Direct Substitute (22AR5KLFTR): Manufactured by TT Electronics/BI, this part matches all electrical specifications and physical termination requirements. Package dimensions are identical (0.138" x 0.126" face, 4.60mm x 3.20mm).

Similar Substitute (ST-32ETA502): Manufactured by Nidec Components Corporation, this part matches all electrical specifications and termination style. Package dimensions differ slightly (0.134" x 0.134" face, 3.40mm x 3.40mm square versus rectangular), representing a minor mechanical variation within acceptable substitution parameters.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active production status with full compliance certifications. The 22AR5KLFTR offers direct dimensional compatibility with identical rectangular package geometry, making it the primary substitute for applications with strict PCB layout constraints. The ST-32ETA502 provides functional equivalence with a square package footprint that differs by 0.004" in each dimension; this part is suitable for designs where package geometry flexibility exists. Both substitute parts carry RoHS compliance and unlimited MSL ratings, matching the environmental and handling requirements of the original 3313J-1-502G.

Frequently Asked Questions (FAQ)

Q: Can the 22AR5KLFTR replace the 3313J-1-502G in existing designs? A: Yes. The 22AR5KLFTR matches all electrical parameters and physical termination specifications. Package dimensions are identical, requiring no PCB layout modifications.

Q: What is the primary difference between the ST-32ETA502 and the original part? A: The ST-32ETA502 features a square package (0.134" x 0.134") compared to the rectangular package (0.138" x 0.126") of the 3313J-1-502G. All electrical specifications remain identical. PCB footprint adjustment may be required.

Q: Are all three parts RoHS compliant? A: Yes. The 3313J-1-502G and ST-32ETA502 are ROHS3 compliant. The 22AR5KLFTR is RoHS compliant. All meet environmental regulatory requirements.

Q: Do these parts have the same moisture sensitivity level? A: Yes. All three parts carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Can these parts be used interchangeably in production? A: The 22AR5KLFTR provides direct interchangeability. The ST-32ETA502 requires PCB footprint verification due to package geometry differences, though electrical performance is equivalent.
