Key Parameters

Substitute Part Grouping Explanation

The 78PR5KLF qualifies as a substitute for the 3059P-1-502LF based on matching electrical and functional parameters: identical resistance value (5 kOhms), power rating (1W), tolerance (±10%), temperature coefficient (±100ppm/°C), number of turns (22), adjustment type (side adjustment), resistive material (cermet), and termination style (PC pins). Both components maintain ROHS3 compliance and EAR99 ECCN classification. The primary distinction lies in mounting type: the 3059P-1-502LF uses chassis mount configuration with a rectangular face dimension of 0.315" x 0.190" (8.00mm x 4.83mm), while the 78PR5KLF employs through-hole mounting with a larger rectangular face dimension of 1.250" x 0.195" (31.75mm x 4.95mm). Substitution is valid when circuit board layout and mechanical constraints permit accommodation of the through-hole mounting footprint and increased physical dimensions.

Parameter Comparison

Engineering Selection Recommendations

Both the 3059P-1-502LF and 78PR5KLF maintain active product status with ROHS3 compliance and identical electrical specifications. Selection between these components depends on mechanical integration requirements. The 3059P-1-502LF is specified for chassis mount applications with compact form factor suitable for space-constrained designs. The 78PR5KLF accommodates through-hole mounting with larger physical dimensions, appropriate for applications where board-level integration and mechanical stability through pin insertion are prioritized. Both components carry EAR99 ECCN classification and identical HTSUS coding (8533.40.8050), confirming regulatory equivalence for export and trade purposes.

Frequently Asked Questions (FAQ)

Q: Can the 78PR5KLF directly replace the 3059P-1-502LF in an existing circuit board?

A: Electrical substitution is valid due to identical resistance, power rating, tolerance, temperature coefficient, and adjustment characteristics. However, mechanical compatibility requires verification. The 3059P-1-502LF uses chassis mount with 8.00mm x 4.83mm face dimensions, while the 78PR5KLF uses through-hole mounting with 31.75mm x 4.95mm face dimensions. Board layout and mounting hole patterns must accommodate the larger footprint.

Q: Are the tolerance and temperature coefficient specifications identical?

A: Yes. Both components specify ±10% tolerance and ±100ppm/°C temperature coefficient, ensuring equivalent performance stability across operating temperature ranges.

Q: What is the difference in packaging between these parts?

A: The 3059P-1-502LF is supplied in tube packaging, while the 78PR5KLF is supplied in bulk packaging. This distinction affects handling and inventory management but does not impact electrical or functional performance.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both components are ROHS3 compliant, carry EAR99 ECCN classification, and share identical HTSUS code (8533.40.8050), confirming equivalent regulatory status for procurement and deployment.

Q: What determines whether substitution is appropriate for a specific application?

A: Substitution is appropriate when circuit electrical requirements match the specified 5 kOhm resistance, 1W power rating, and 22-turn adjustment characteristics, and when the circuit board mechanical design accommodates through-hole mounting with the larger 31.75mm x 4.95mm footprint of the 78PR5KLF.
