Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3362H-1-502 are qualified based on the following criteria:

• Electrical specifications: Resistance value (5 kOhms), power rating (0.5W), tolerance (±10%), and temperature coefficient (±100ppm/°C) must match exactly
• Functional design: Single-turn, top-adjustment trimmer potentiometer with cermet resistive element
• Termination and mounting: PC pin through-hole configuration required for PCB compatibility
• Regulatory compliance: HTSUS classification 8533.40.8050 and ECCN EAR99 maintained across all substitutes

Substitute parts are grouped into two categories: direct manufacturer equivalents from Bourns Inc. and cross-manufacturer alternatives from TT Electronics/BI that meet identical electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Bourns Inc.)

The 3362H-1-502LF is the direct equivalent of the 3362H-1-502, maintaining identical electrical specifications, mechanical dimensions, and series designation. The primary distinction is RoHS3 compliance status. Selection of 3362H-1-502LF is appropriate for applications requiring lead-free termination or RoHS compliance certification.

Cross-Manufacturer Alternatives (TT Electronics/BI)

The 25PR5KLF, 72PR5KLF, and 72PMR5KLF are qualified substitutes from TT Electronics/BI. All three parts match the electrical specifications and functional design of the 3362H-1-502. Physical dimensions vary: the 25PR5KLF maintains a compact rectangular footprint similar to the Bourns part, while the 72-series parts feature a larger square footprint. Packaging differs between tube (25PR5KLF) and bulk (72-series). All cross-manufacturer alternatives carry RoHS3 or RoHS compliance certification.

Selection among cross-manufacturer alternatives depends on PCB layout constraints and packaging requirements. The 25PR5KLF is recommended for space-constrained applications requiring tube packaging. The 72-series parts are suitable for applications where larger footprint dimensions are acceptable and bulk packaging is preferred.

Frequently Asked Questions (FAQ)

Q: Can the 3362H-1-502LF be used as a direct replacement for the 3362H-1-502?

A: Yes. The 3362H-1-502LF is electrically and mechanically identical to the 3362H-1-502. The primary difference is RoHS3 compliance status. Both parts share the same face dimensions (0.275" x 0.260"), resistance value (5 kOhms), power rating (0.5W), and PC pin termination.

Q: What are the physical dimension differences between substitute parts?

A: The 3362H-1-502 and 3362H-1-502LF have identical rectangular face dimensions of 0.275" x 0.260" (6.99mm x 6.60mm). The 25PR5KLF has a slightly smaller square face of 0.270" x 0.270" (6.86mm x 6.86mm). The 72-series parts (72PR5KLF and 72PMR5KLF) have larger square faces of 0.375" x 0.375" (9.53mm x 9.53mm). PCB layout verification is required when substituting parts with different footprints.

Q: Are all substitute parts RoHS compliant?

A: The 3362H-1-502 is RoHS non-compliant. The 3362H-1-502LF is ROHS3 compliant. The 25PR5KLF is RoHS compliant. The 72PR5KLF and 72PMR5KLF are ROHS3 compliant. Selection depends on application regulatory requirements.

Q: What is the difference between tube and bulk packaging?

A: The 3362H-1-502, 3362H-1-502LF, and 25PR5KLF are supplied in tube packaging. The 72PR5KLF and 72PMR5KLF are supplied in bulk packaging. Packaging selection affects inventory management and component handling procedures but does not impact electrical or mechanical performance.

Q: Can cross-manufacturer parts (TT Electronics/BI) be used interchangeably with Bourns parts?

A: Yes, provided PCB layout accommodates the physical dimension differences. All cross-manufacturer alternatives (25PR5KLF, 72PR5KLF, 72PMR5KLF) match the electrical specifications, functional design, and termination style of the 3362H-1-502. Verification of footprint compatibility is required before substitution.
