Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RJ-6P502 is determined by strict equivalence across the following critical parameters: resistance value (5 kOhms), power rating (0.5W), tolerance (±10%), temperature coefficient (±100ppm/°C), number of turns (1), adjustment type (top adjustment), resistive material (cermet), mounting type (through hole), and termination style (PC pins). All identified substitute parts meet these electrical and mechanical requirements. Physical dimensions and packaging formats vary among substitutes but do not affect functional interchangeability in circuit applications. Compliance certifications (RoHS, REACH, ECCN) are provided for each part to support regulatory and procurement requirements.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active product status and meet the electrical specifications of the RJ-6P502. Selection among substitutes should be based on the following factors:

RoHS Compliance: The RJ-6P502, 3329H-1-502LF, 72PR5KLF, 72PMR5KLF, and 82PR5KLF are ROHS3 compliant. The 25PR5KLF carries RoHS compliance without the ROHS3 designation. For applications requiring ROHS3 certification, the five ROHS3-compliant options are preferred.

REACH Status: The 3329H-1-502LF is REACH Affected. The RJ-6P502, 25PR5KLF, 72PR5KLF, 72PMR5KLF, and 82PR5KLF are REACH Unaffected. For applications subject to REACH regulations, REACH Unaffected parts are recommended.

Physical Dimensions: Dimensional differences exist among substitutes. The RJ-6P502 features a round 0.276" diameter form factor. Round alternatives include the 3329H-1-502LF (0.250" diameter) and 82PR5KLF (0.250" diameter). Square form factors are available in the 25PR5KLF (0.270" x 0.270") and 72PR5KLF/72PMR5KLF (0.375" x 0.375"). PCB layout constraints should guide selection based on available mounting space.

Packaging Format: Bulk packaging is available in RJ-6P502, 72PR5KLF, 72PMR5KLF, and 82PR5KLF. Tube packaging is available in 3329H-1-502LF and 25PR5KLF. Procurement volume and handling requirements should inform packaging selection.

Frequently Asked Questions (FAQ)

Q: Can the 3329H-1-502LF replace the RJ-6P502 in all applications?

A: The 3329H-1-502LF meets all electrical specifications (5 kOhms, 0.5W, ±10% tolerance, ±100ppm/°C temperature coefficient, 1 turn, top adjustment, cermet material, through-hole mounting, PC pin termination). Physical dimensions differ (0.250" diameter versus 0.276" diameter), which may affect PCB layout. REACH Affected status requires evaluation for applications subject to REACH regulations.

Q: What is the difference between the 72PR5KLF and 72PMR5KLF?

A: Both parts are manufactured by TT Electronics/BI with identical electrical specifications and physical dimensions (0.375" x 0.375" square form factor). The primary distinction is the base product number designation (72PR versus 72PMR). Both are ROHS3 compliant, REACH Unaffected, and available in bulk packaging.

Q: Are there dimensional constraints when substituting the RJ-6P502?

A: Yes. The RJ-6P502 is round with 0.276" diameter. Substitutes include round options (3329H-1-502LF and 82PR5KLF at 0.250" diameter) and square options (25PR5KLF at 0.270" x 0.270", and 72PR5KLF/72PMR5KLF at 0.375" x 0.375"). PCB layout must accommodate the selected form factor.

Q: Which substitute offers the closest dimensional match to the RJ-6P502?

A: The 3329H-1-502LF and 82PR5KLF both feature round form factors at 0.250" diameter, providing the closest dimensional profile to the RJ-6P502's 0.276" diameter round design.

Q: Does packaging format affect electrical performance?

A: No. Bulk and tube packaging formats do not affect electrical performance or functional interchangeability. Packaging selection is based on procurement volume, inventory management, and handling requirements.

Q: Are all substitutes suitable for ROHS3-compliant applications?

A: Five of the six substitutes are ROHS3 compliant: 3329H-1-502LF, 72PR5KLF, 72PMR5KLF, 82PR5KLF, and the main part RJ-6P502. The 25PR5KLF carries RoHS compliance without ROHS3 designation. For ROHS3-required applications, use the five ROHS3-compliant options.
