Key Parameters

Substitute Part Grouping Explanation

The 3059P-1-102LF qualifies as a direct substitute for the 3059P-1-102 based on identical electrical and mechanical parameters. Substitution is determined by the following critical parameters that must match exactly:

• Resistance value: 1 kOhms
• Power rating: 1W
• Tolerance: ±10%
• Temperature coefficient: ±100ppm/°C
• Number of turns: 22
• Adjustment type: Side Adjustment
• Resistive material: Cermet
• Mounting type: Chassis Mount
• Termination style: PC Pins
• Physical dimensions: Rectangular - 0.315" x 0.190" Face (8.00mm x 4.83mm)
• Series family: Trimpot® 3059 - Sealed

The primary distinction between these parts is the RoHS compliance status, with the 3059P-1-102LF meeting ROHS3 compliance requirements while the original 3059P-1-102 is RoHS non-compliant.

Parameter Comparison

Engineering Selection Recommendations

The 3059P-1-102LF is a direct functional equivalent to the 3059P-1-102. Both parts maintain identical electrical performance and mechanical compatibility. The selection between these parts should be based on regulatory and compliance requirements:

• Use 3059P-1-102LF for applications requiring ROHS3 compliance or for new design implementations where RoHS compliance is mandated.
• Use 3059P-1-102 only when legacy designs specifically require the non-compliant variant or when existing inventory must be consumed.

Both parts are active products with current manufacturing status and adequate inventory availability. The 3059P-1-102LF offers 1166 units in stock compared to 766 units for the original part.

Frequently Asked Questions (FAQ)

Q: Are the 3059P-1-102 and 3059P-1-102LF electrically identical?

A: Yes. Both parts have identical resistance (1 kOhms), power rating (1W), tolerance (±10%), temperature coefficient (±100ppm/°C), and all other electrical specifications.

Q: Can I use 3059P-1-102LF as a drop-in replacement for 3059P-1-102?

A: Yes. The parts are mechanically and electrically identical with matching dimensions (0.315" x 0.190" face), termination style (PC Pins), mounting type (Chassis Mount), and adjustment mechanism (Side Adjustment, 22 turns).

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

A: The primary difference is RoHS compliance status. The 3059P-1-102LF meets ROHS3 compliance requirements, while the 3059P-1-102 is RoHS non-compliant. Both parts are REACH Affected and share identical ECCN (EAR99) and HTSUS (8533.40.8050) classifications.

Q: Which part should I specify for a new design?

A: Specify 3059P-1-102LF for new designs to ensure compliance with current RoHS regulations and to benefit from improved inventory availability.

Q: Are there any performance differences between these parts?

A: No. Both parts deliver identical performance across all electrical and mechanical parameters including cermet resistive material, sealed construction, and 22-turn adjustment resolution.
