Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3386T-1-201 is determined by strict equivalence across the following electrical and mechanical parameters:

• Resistance value: 200 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 substitute parts meet these criteria. Physical dimensions and packaging formats may vary while maintaining functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

All three parts—3386T-1-201, 25PR200LF, and 82PR200LF—are functionally equivalent based on electrical specifications and mechanical compatibility. Selection between them should be based on the following factors:

Compliance Requirements: The 25PR200LF and 82PR200LF offer RoHS compliance (RoHS Compliant and ROHS3 Compliant respectively), while the 3386T-1-201 is RoHS non-compliant. For applications requiring RoHS compliance, either substitute part is suitable. The 25PR200LF and 82PR200LF are also REACH Unaffected, whereas the 3386T-1-201 is REACH Affected.

Physical Form Factor: The 3386T-1-201 features a larger square footprint (0.375" x 0.375"), the 25PR200LF uses a smaller square footprint (0.270" x 0.270"), and the 82PR200LF employs a round form factor (0.250" diameter). PCB layout constraints and available space determine which form factor is appropriate.

Packaging Format: The 3386T-1-201 and 25PR200LF are supplied in tube packaging, while the 82PR200LF is supplied in bulk packaging. Procurement and handling requirements may influence packaging selection.

Inventory Availability: Current stock levels are 1012 pcs (3386T-1-201), 5068 pcs (25PR200LF), and 1602 pcs (82PR200LF).

Frequently Asked Questions (FAQ)

Q: Can the 25PR200LF or 82PR200LF be used as direct replacements for the 3386T-1-201?

A: Yes. Both parts meet all electrical and mechanical substitution criteria: 200 Ohm resistance, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, 1 turn, top adjustment, cermet material, through-hole mounting, and PC pin termination. Physical dimensions and packaging differ but do not affect functional equivalence.

Q: What are the key differences between the substitute parts?

A: The primary differences are physical form factor (square vs. round), footprint size, packaging format (tube vs. bulk), and compliance certifications. The 25PR200LF and 82PR200LF offer improved RoHS and REACH compliance compared to the 3386T-1-201.

Q: Does the difference in physical dimensions affect circuit performance?

A: No. The electrical performance is determined by the resistance value, power rating, tolerance, and temperature coefficient—all of which are identical across the three parts. Physical dimensions affect only PCB layout and mounting considerations.

Q: Which part should be selected for new designs?

A: For new designs, the 25PR200LF or 82PR200LF are preferred due to RoHS and REACH compliance. Selection between these two depends on available PCB space and packaging requirements.

Q: Are there any restrictions on substituting between these parts in existing applications?

A: Substitution is restricted only by physical space constraints on the PCB. The larger 3386T-1-201 cannot be substituted into a layout designed for the smaller 25PR200LF or 82PR200LF. Conversely, the smaller parts can substitute into layouts designed for the larger 3386T-1-201 if mechanical mounting provisions are adjusted.
