Key Parameters

Substitute Part Grouping Explanation

The Bourns 3362P-1-102 qualifies as a direct substitute for the 3366P-1-102 based on the following critical parameters:

• Identical resistance value: 1 kOhms
• Identical power rating: 0.5W (1/2W)
• Identical tolerance: ±10%
• Identical temperature coefficient: ±100ppm/°C
• Identical number of turns: 1
• Identical adjustment type: Top Adjustment
• Identical resistive material: Cermet
• Identical mounting type: Through Hole
• Identical termination style: PC Pins

The 3362P series represents the current-generation equivalent within the Bourns trimmer potentiometer portfolio, with mechanical dimensions that remain within acceptable tolerance for PCB footprint compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 3362P-1-102 is the recommended substitute for the obsolete 3366P-1-102. Selection is based on:

• Active product status with current manufacturing support
• Identical electrical specifications across all critical parameters
• Mechanical dimensions within acceptable PCB layout tolerance
• Equivalent regulatory compliance (ECCN: EAR99; HTSUS: 8533.40.8050)
• Superior inventory availability (4300 pcs vs. 879 pcs)

For new designs and production continuity, the 3362P-1-102 should be specified in place of the 3366P-1-102.

Frequently Asked Questions (FAQ)

Q: Are the 3366P-1-102 and 3362P-1-102 electrically identical?

A: Yes. Both components share identical resistance (1 kOhms), power rating (0.5W), tolerance (±10%), temperature coefficient (±100ppm/°C), number of turns (1), and adjustment type (top adjustment).

Q: Will the 3362P-1-102 fit the same PCB footprint as the 3366P-1-102?

A: The mechanical dimensions are similar with minor variations. The 3366P-1-102 has a square face of 0.276" x 0.276" (7.00mm x 7.00mm), while the 3362P-1-102 has a rectangular face of 0.275" x 0.260" (6.99mm x 6.60mm). Both use identical PC pin termination and through-hole mounting, making them compatible for standard PCB layouts.

Q: What is the difference between the 3366 and 3362 series?

A: The 3362 series is the current-generation Trimpot® sealed trimmer potentiometer line that supersedes the obsolete 3366 series. The 3362 series maintains electrical equivalence while offering active product status and improved availability.

Q: Can I use the 3362P-1-102 in existing inventory of 3366P-1-102 applications?

A: Yes. The 3362P-1-102 is a direct substitute with identical electrical and mechanical specifications suitable for all applications previously using the 3366P-1-102.

Q: What packaging is available for the 3362P-1-102?

A: The 3362P-1-102 is supplied in tube packaging, with 4300 pcs currently in stock.
