Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EVU-TW1B24A13 is determined by the following critical parameters:

• Resistance value: 1 kOhms (exact match required)
• Adjustment type: Top Adjustment (functional requirement for user interface)
• Termination style: PC Pins (PCB compatibility requirement)
• Mounting type: Through Hole (mechanical fit requirement)
• Number of turns: 1 (operational characteristic)

The 3352T-1-102LF from Bourns Inc. satisfies all mandatory substitution criteria. While the Bourns component offers higher power dissipation (0.5W versus 0.01W) and tighter tolerance (±20% versus ±30%), these represent performance enhancements rather than incompatibilities. The increased power rating provides additional thermal margin in the application, and improved tolerance enhances precision without creating functional conflicts.

Engineering Selection Recommendations

The 3352T-1-102LF is the qualified substitute for the obsolete EVU-TW1B24A13. Selection is based on the following engineering factors:

• All critical electrical parameters match: resistance, adjustment type, termination, and mounting configuration
• The substitute maintains active product status with established supply chain availability
• RoHS3 compliance and REACH compliance status of the Bourns component satisfy modern regulatory requirements
• Enhanced power rating (0.5W) and improved tolerance (±20%) provide performance margin without introducing incompatibility
• Identical moisture sensitivity classification ensures equivalent environmental performance
• Both components share the same ECCN and HTSUS classifications, confirming regulatory equivalence

Frequently Asked Questions (FAQ)

Q: Can the 3352T-1-102LF directly replace the EVU-TW1B24A13 in existing designs?

A: Yes. Both components share identical resistance (1 kOhms), adjustment type (top adjustment), termination (PC pins), and mounting configuration (through hole). The substitute's higher power rating and tighter tolerance represent performance improvements that do not create functional conflicts.

Q: What is the significance of the power rating difference (0.01W vs. 0.5W)?

A: The EVU-TW1B24A13 is rated for 0.01W dissipation, while the 3352T-1-102LF is rated for 0.5W. In applications where the original component operated within its power budget, the substitute will operate with additional thermal margin, improving reliability without affecting circuit function.

Q: Does the tolerance difference (±30% vs. ±20%) affect circuit performance?

A: The 3352T-1-102LF offers tighter tolerance, meaning its actual resistance value will be closer to the nominal 1 kOhms specification. This enhances precision in applications requiring accurate resistance values. Circuits designed for the original ±30% tolerance will function correctly with the improved ±20% tolerance.

Q: Are there physical dimension considerations for PCB layout?

A: The 3352T-1-102LF dimensions are specified as 0.350" diameter by 0.150" height. The original EVU-TW1B24A13 dimensions are not provided in available documentation. Verify mechanical fit within your PCB footprint before final assembly.

Q: What is the product status significance?

A: The EVU-TW1B24A13 is obsolete and no longer manufactured. The 3352T-1-102LF maintains active product status with established manufacturing and distribution channels, ensuring long-term component availability for production and field service applications.
