Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3262W-1-101 are classified based on electrical and mechanical parameter matching:

Direct Equivalent (Same Manufacturer): The 3262W-1-101LF is manufactured by Bourns Inc. and maintains identical electrical specifications (100 Ohms, 0.25W, ±10% tolerance, ±100ppm/°C, 12-turn cermet construction) and mechanical form factor. The primary distinction is RoHS compliance status and termination designation (LF suffix indicates lead-free).

Cross-Manufacturer Substitute: The 64WR100LF manufactured by TT Electronics/BI matches all critical electrical parameters (100 Ohms, 0.25W, ±10% tolerance, ±100ppm/°C, 12-turn cermet) and mounting characteristics (through-hole PC pins, top adjustment). Minor dimensional variation exists in the face dimension (0.250" x 0.165" versus 0.250" x 0.170"), which remains within acceptable tolerance for standard PCB footprints designed for the 3262W series.

Key Parameters for Substitution Compatibility:

• Resistance value: 100 Ohms
• Power rating: 0.25W
• Tolerance: ±10%
• Temperature coefficient: ±100ppm/°C
• Number of turns: 12
• Adjustment type: Top Adjustment
• Resistive material: Cermet
• Mounting: Through Hole with PC Pins
• Face dimension tolerance: ±0.005" acceptable variation

Parameter Comparison

Engineering Selection Recommendations

For RoHS-Compliant Applications: The 3262W-1-101LF is the direct equivalent with ROHS3 compliance, maintaining identical electrical and mechanical specifications while meeting lead-free manufacturing requirements. This part is preferred for new designs subject to RoHS directives.

For REACH-Unaffected Supply Chain Requirements: The 64WR100LF offers REACH Unaffected status, eliminating regulatory documentation requirements in certain jurisdictions. This cross-manufacturer substitute maintains all critical electrical parameters and is suitable for applications where regulatory simplification is a priority.

For Legacy System Maintenance: The original 3262W-1-101 remains available for direct replacement in existing designs where RoHS compliance is not mandated and regulatory status is not a constraint.

All three parts are actively manufactured and maintain identical functional performance within the specified tolerance and temperature coefficient ranges.

Frequently Asked Questions (FAQ)

Q: Can the 3262W-1-101LF be used as a direct replacement for the 3262W-1-101?

A: Yes. Both parts are manufactured by Bourns Inc. and share identical electrical specifications (100 Ohms, 0.25W, ±10% tolerance, ±100ppm/°C, 12-turn cermet) and mechanical dimensions. The LF designation indicates lead-free termination and ROHS3 compliance. No circuit modifications are required.

Q: Is the 64WR100LF mechanically compatible with PCB footprints designed for the 3262W-1-101?

A: Yes. The 64WR100LF maintains the same through-hole PC pin configuration and top adjustment interface. The face dimension is 0.250" x 0.165" compared to 0.250" x 0.170" for the 3262W-1-101. This 0.005" variation is within standard PCB footprint tolerances and does not affect mounting or electrical performance.

Q: What are the key electrical parameters that must match for substitution?

A: Resistance value (100 Ohms), power rating (0.25W), tolerance (±10%), temperature coefficient (±100ppm/°C), number of turns (12), and resistive material (cermet) must all match. These parameters determine circuit tuning range, stability, and power dissipation characteristics.

Q: Are there compliance differences between these three parts?

A: Yes. The 3262W-1-101 is RoHS non-compliant and REACH Affected. The 3262W-1-101LF is ROHS3 Compliant and REACH Affected. The 64WR100LF is RoHS Compliant and REACH Unaffected. Selection depends on regulatory requirements for your application and target market.

Q: Can these parts be used interchangeably in the same design revision?

A: Yes, provided compliance and supply chain requirements are met. All three parts deliver identical electrical performance and are mechanically compatible with standard 3262-series PCB footprints. Design documentation should specify the selected part number to ensure procurement consistency.
