Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3252W-1-102 are identified based on the following critical parameters that determine functional equivalence:

• Resistance value: 1 kOhms
• Power rating: 0.75W
• Tolerance: ±10%
• Temperature coefficient: ±100ppm/°C
• Number of turns: 25
• Adjustment type: Top Adjustment
• Resistive material: Cermet
• Mounting type: Chassis Mount
• Termination style: PC Pins
• Physical dimensions: Rectangular - 0.500" x 0.220" Face

The 3252W-1-102LF variant maintains all electrical and mechanical specifications identical to the main part, with the primary distinction being RoHS compliance status. Both parts belong to the same Trimpot® 3252 sealed series and share the same base product number (3252W), confirming direct substitutability in applications where component-level compliance requirements align.

Parameter Comparison

Engineering Selection Recommendations

Both the 3252W-1-102 and 3252W-1-102LF are active production parts with identical electrical and mechanical specifications. Selection between these variants is determined by regulatory and compliance requirements:

The 3252W-1-102LF is the appropriate choice for applications subject to RoHS3 compliance mandates or where lead-free termination is contractually required. The 3252W-1-102 remains suitable for applications without RoHS compliance constraints or legacy systems where lead-based termination is acceptable.

Both parts share the same REACH affected status and EAR99 export classification. Packaging is supplied in tube format for both variants. The interchangeability of these parts at the circuit level is complete, with substitution decisions driven solely by compliance documentation and supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Can the 3252W-1-102LF directly replace the 3252W-1-102 in existing designs?

A: Yes. The 3252W-1-102LF is electrically and mechanically identical to the 3252W-1-102. Both parts have the same resistance value (1 kOhms), power rating (0.75W), tolerance (±10%), temperature coefficient (±100ppm/°C), number of turns (25), adjustment type (top), resistive material (cermet), mounting type (chassis), termination style (PC pins), and physical dimensions. Direct substitution is possible without circuit modification.

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

A: The primary difference is RoHS compliance status. The 3252W-1-102LF is ROHS3 compliant, while the 3252W-1-102 is RoHS non-compliant. All other specifications, including electrical performance and mechanical form factor, are identical.

Q: Are both parts available in the same packaging format?

A: Yes. Both the 3252W-1-102 and 3252W-1-102LF are supplied in tube packaging.

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

A: Specify the 3252W-1-102LF if your application or customer requirements mandate RoHS3 compliance. Specify the 3252W-1-102 if RoHS compliance is not a requirement and lead-based termination is acceptable.

Q: Do these parts have the same temperature performance?

A: Yes. Both parts have an identical temperature coefficient of ±100ppm/°C, ensuring equivalent thermal stability across the operating range.

Q: Are there any differences in the number of adjustment turns?

A: Both parts have 25 turns. The 3252W-1-102LF specification lists this as 25.0 turns, which is a notation difference only and does not indicate a functional variation.
