Substitute Part Grouping Explanation

Substitute parts for the 3292X-1-503 are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution criteria are:

• Identical resistance value: 50 kOhms
• Identical power rating: 0.5W (1/2W)
• Identical tolerance: ±10%
• Identical temperature coefficient: ±100ppm/°C
• Identical number of turns: 25
• Identical adjustment type: Side Adjustment
• Identical resistive material: Cermet
• Identical mounting type: Through Hole
• Identical termination style: PC Pins
• Identical physical dimensions: Rectangular - 0.375" x 0.150" Face (9.53mm x 3.81mm)
• Same series: Trimpot® 3292 - Sealed

The 3292X-1-503LF meets all these criteria and is classified as a direct manufacturer equivalent with enhanced compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the 3292X-1-503 and 3292X-1-503LF are active production parts from Bourns Inc. with identical electrical and mechanical specifications. The primary distinction is regulatory compliance status.

The 3292X-1-503LF carries ROHS3 compliance, making it the preferred selection for applications subject to RoHS 3 directive requirements or for manufacturers implementing lead-free manufacturing processes. Both parts maintain REACH Affected status and EAR99 export classification.

Selection between these parts should be based on specific project compliance requirements and supply chain constraints. Both parts are functionally and mechanically interchangeable within the Trimpot® 3292 sealed series.

Frequently Asked Questions (FAQ)

Q: Are the 3292X-1-503 and 3292X-1-503LF electrically identical?

A: Yes. Both parts have identical resistance value (50 kOhms), power rating (0.5W), tolerance (±10%), temperature coefficient (±100ppm/°C), and all other electrical specifications.

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

A: The 3292X-1-503LF is ROHS3 compliant, while the 3292X-1-503 is RoHS non-compliant. All other specifications, including physical dimensions, mounting type, and termination style, are identical.

Q: Can I use the 3292X-1-503LF as a direct replacement for the 3292X-1-503?

A: Yes. The parts are mechanically and electrically interchangeable. The 3292X-1-503LF can be used as a direct substitute in any application designed for the 3292X-1-503.

Q: Are there any packaging differences between these parts?

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

Q: Which part should I specify for new designs?

A: For new designs, specify the 3292X-1-503LF to ensure compliance with current RoHS 3 requirements and lead-free manufacturing standards.

Q: Do these parts have the same physical footprint?

A: Yes. Both parts have identical rectangular dimensions of 0.375" x 0.150" face (9.53mm x 3.81mm) and are designed for through-hole mounting with PC pin termination.
