Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3386T-1-504 is determined by strict equivalence across the following critical parameters:

• Resistance value: 500 kOhms
• Power rating: 0.5W (1/2W)
• Tolerance: ±10%
• Temperature coefficient: ±100ppm/°C
• Number of turns: 1
• Adjustment type: Top Adjustment
• Resistive material: Cermet
• Mounting type: Through Hole
• Termination style: PC Pins
• Physical dimensions: Square - 0.375" x 0.375" (9.53mm x 9.53mm)

The 72PR500KLF from TT Electronics/BI meets all these electrical and mechanical criteria, qualifying it as a direct equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The 72PR500KLF qualifies as a direct electrical and mechanical equivalent to the 3386T-1-504. Selection between these parts should be based on product status and regulatory compliance:

The 3386T-1-504 is RoHS non-compliant and REACH Affected. The 72PR500KLF is RoHS3 Compliant and REACH Unaffected. For applications requiring RoHS3 compliance or REACH compliance, the 72PR500KLF is the appropriate selection. Both parts carry the same ECCN (EAR99) and HTSUS (8533.40.8050) classifications.

Frequently Asked Questions (FAQ)

Q: Can the 72PR500KLF directly replace the 3386T-1-504 in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent across all specified parameters: 500 kOhms resistance, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, 1-turn top adjustment, cermet material, through-hole mounting with PC pins, and identical 0.375" x 0.375" square dimensions.

Q: What is the primary difference between these two parts?

A: The primary differences are regulatory compliance status and packaging. The 72PR500KLF is RoHS3 Compliant and REACH Unaffected, while the 3386T-1-504 is RoHS non-compliant and REACH Affected. The 3386T-1-504 is supplied in Tube packaging; the 72PR500KLF is supplied in Bulk packaging.

Q: Are there any electrical performance differences?

A: No. Both parts share identical electrical specifications: 500 kOhms resistance, 0.5W power rating, ±10% tolerance, and ±100ppm/°C temperature coefficient.

Q: Which part should be selected for new designs?

A: For new designs requiring regulatory compliance, the 72PR500KLF is recommended due to its RoHS3 Compliant and REACH Unaffected status. For applications without compliance requirements, either part meets the electrical and mechanical specifications.

Q: Are the physical dimensions identical?

A: Yes. Both parts are square format with 0.375" x 0.375" face dimensions (9.53mm x 9.53mm), ensuring identical PCB footprint and mounting compatibility.
