Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3386G-1-501LF are qualified based on the following criteria:

• Resistance value: 500 Ohms (exact match required)
• Power rating: 0.5W / 1/2W (exact match required)
• Tolerance: ±10% (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Number of turns: 1 (exact match required)
• Adjustment type: Top Adjustment (exact match required)
• Resistive material: Cermet (exact match required)
• Mounting type: Through Hole (exact match required)
• Termination style: PC Pins (exact match required)

All identified substitutes meet these core electrical and mechanical parameters. Variations in physical dimensions and packaging format are noted but do not affect functional equivalence within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and meet RoHS compliance requirements. The 72PR500LF and 82PR500LF are available in bulk packaging, while the 25PR500LF is supplied in tube format matching the original part packaging. Physical dimensions vary across the substitute options; PCB layout and mechanical clearance must be verified for applications where space constraints are critical. All parts share identical electrical specifications and functional performance within the defined parameter set.

Frequently Asked Questions (FAQ)

Q: Can 25PR500LF be used as a direct replacement for 3386G-1-501LF?

A: The 25PR500LF meets all electrical and functional specifications. Physical dimensions differ (0.270" vs 0.375" face), requiring verification of PCB layout compatibility and available mounting space.

Q: What is the difference between 72PR500LF and 82PR500LF?

A: Both parts are electrically equivalent with identical specifications. The 72PR500LF has a square physical form (0.375" x 0.375"), while the 82PR500LF has a round form (0.250" diameter). Selection depends on available PCB space and mechanical mounting requirements.

Q: Are all substitutes RoHS compliant?

A: Yes. The 3386G-1-501LF, 72PR500LF, and 82PR500LF are ROHS3 compliant. The 25PR500LF is RoHS compliant. All meet environmental regulatory requirements.

Q: Does packaging format affect electrical performance?

A: No. Tube and bulk packaging formats do not affect component electrical characteristics or performance. Selection is based on procurement and inventory management requirements.

Q: Can these parts be used interchangeably in all applications?

A: Electrical and functional interchangeability is confirmed. Physical form factor differences require PCB layout verification to ensure mechanical fit and clearance compatibility.
