Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3262X-1-105 is determined by strict equivalence across the following critical parameters:

• Resistance value: 1 MOhms
• Power rating: 0.25W (1/4W)
• Tolerance: ±10%
• Temperature coefficient: ±100ppm/°C
• Number of turns: 12
• Adjustment type: Side Adjustment
• Resistive material: Cermet
• Mounting type: Through Hole
• Termination style: PC Pins
• Physical dimensions: Rectangular - 0.250" x 0.170" Face (6.35mm x 4.32mm)
• Series family: Trimpot® 3262 - Sealed

The 3262X-1-105LF qualifies as a direct substitute because it maintains identical electrical and mechanical specifications across all parameters listed above. Differences in RoHS compliance status do not affect functional equivalence but may impact regulatory requirements for specific applications.

Parameter Comparison

Engineering Selection Recommendations

The 3262X-1-105LF is a direct functional equivalent to the 3262X-1-105. Both parts are active products from Bourns Inc. with identical electrical and mechanical specifications. Selection between these two parts should be based on regulatory compliance requirements:

• Use 3262X-1-105 when RoHS non-compliant components are acceptable for the application.
• Use 3262X-1-105LF when ROHS3 compliance is required by design specifications or end-use regulations.

Both parts carry REACH Affected status and share identical ECCN and HTSUS classifications. Current inventory levels support either selection: 1155 units of 3262X-1-105 and 966 units of 3262X-1-105LF are available.

Frequently Asked Questions (FAQ)

Q: Can the 3262X-1-105LF replace the 3262X-1-105 in existing designs?

A: Yes. The 3262X-1-105LF is functionally identical to the 3262X-1-105 across all electrical and mechanical parameters. Direct substitution is possible without circuit or layout modifications.

Q: What is the difference between these two part numbers?

A: The primary difference is RoHS compliance status. The 3262X-1-105LF is ROHS3 compliant, while the 3262X-1-105 is RoHS non-compliant. All other specifications, including resistance, power rating, tolerance, temperature coefficient, physical dimensions, and termination style, are identical.

Q: Are there any packaging differences between these parts?

A: Both parts are supplied in tube packaging. Physical dimensions and form factors are identical: rectangular 0.250" x 0.170" face (6.35mm x 4.32mm).

Q: Which part should I select for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS3 compliance, specify 3262X-1-105LF. For applications without RoHS compliance mandates, either part is acceptable based on availability and lead time.

Q: Are both parts still in active production?

A: Yes. Both the 3262X-1-105 and 3262X-1-105LF are listed as active products with current inventory in stock.
