Substitute Part Grouping Explanation

The 3059Y-1-104LF is a direct equivalent substitute for the 3059Y-1-104. Substitution is valid based on identical electrical and mechanical parameters: both parts share the same resistance value (100 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), and physical dimensions (8.00mm x 4.83mm). The primary distinction is RoHS compliance status, with the 3059Y-1-104LF meeting ROHS3 compliance requirements while the original part is RoHS non-compliant. Both parts belong to the same Trimpot® 3059 sealed series and maintain identical functional specifications.

Parameter Comparison

Engineering Selection Recommendations

The 3059Y-1-104LF is the recommended equivalent substitute for the 3059Y-1-104. Both parts are active products with identical electrical and mechanical specifications. Selection between these parts should be based on compliance requirements: the 3059Y-1-104LF meets ROHS3 compliance, making it suitable for applications subject to RoHS regulations. The 3059Y-1-104 remains available for applications where RoHS compliance is not mandated. Both parts maintain REACH affected status and EAR99 export classification. Inventory availability is adequate for both variants, with the 3059Y-1-104LF offering slightly higher stock levels at 1085 units.

Frequently Asked Questions (FAQ)

Q: Are the 3059Y-1-104 and 3059Y-1-104LF electrically identical?

A: Yes. Both parts have identical electrical specifications: 100 kOhms resistance, 1W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, and 22-turn adjustment range.

Q: What is the difference between these two parts?

A: The primary difference is RoHS compliance status. The 3059Y-1-104LF is ROHS3 compliant, while the 3059Y-1-104 is RoHS non-compliant. All other specifications, including mechanical dimensions, mounting type, and termination style, are identical.

Q: Can I use the 3059Y-1-104LF as a direct replacement for the 3059Y-1-104?

A: Yes, the 3059Y-1-104LF is a direct equivalent substitute. It shares identical physical dimensions (8.00mm x 4.83mm), mounting configuration (chassis mount), and termination style (PC pins), ensuring mechanical and electrical compatibility.

Q: Which part should I select for new designs?

A: For new designs subject to RoHS regulations, select the 3059Y-1-104LF. For applications without RoHS requirements, either part is suitable based on availability and supply chain considerations.

Q: Are there any packaging differences?

A: Both parts are supplied in tube packaging. No packaging format differences exist between the two variants.

Q: Do both parts have the same export classification?

A: Yes. Both the 3059Y-1-104 and 3059Y-1-104LF are classified as EAR99 and share the same HTSUS code (8533.40.8050).
