Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1623849-9 is determined by strict equivalence across the following critical parameters:

• Electrical Specifications: Resistance value (5 kOhms), power rating (0.5W), tolerance (±10%), and temperature coefficient (±100ppm/°C) must match exactly
• Mechanical Configuration: Number of turns (25), adjustment type (top adjustment), mounting method (through hole), and termination style (PC pins) must be identical
• Material Composition: Resistive element material (cermet) must be equivalent
• Physical Dimensions: Form factor classification (rectangular) must align with the original design envelope

The Bourns Inc. PV36W502C01B00 satisfies all substitution criteria as a direct functional equivalent with active product status.

Frequently Asked Questions (FAQ)

Q: Can the Bourns PV36W502C01B00 be used as a direct replacement for the TE Connectivity 1623849-9 in existing designs?

A: Yes. The Bourns part is electrically and mechanically equivalent across all specified parameters. The 5 kOhm resistance, 0.5W power rating, 25-turn adjustment, cermet material, and PC pin termination are identical. Physical dimensions differ slightly (9.60mm x 5.00mm versus 9.50mm x 4.70mm), but both maintain rectangular form factor classification suitable for through-hole PC board mounting.

Q: What is the significance of the product status difference between the two parts?

A: The TE Connectivity 1623849-9 is classified as obsolete, indicating discontinued production and limited remaining inventory. The Bourns PV36W502C01B00 maintains active product status with ongoing manufacturing, ensuring availability for new production runs and future procurement requirements.

Q: Are there compliance differences between the original and substitute part?

A: The Bourns substitute carries explicit ROHS3 compliance certification and REACH affected status designation. The original TE Connectivity part does not specify these compliance certifications. Both parts share the same ECCN (EAR99) and HTSUS classification.

Q: How do the physical dimensions affect component placement?

A: Both parts maintain rectangular form factor classification with similar overall dimensions. The Bourns part measures 9.60mm x 5.00mm compared to the original 9.50mm x 4.70mm. These minor dimensional variations are within typical PCB layout tolerances for through-hole components and do not affect functional compatibility or mounting hole alignment.

Q: What packaging format is available for the substitute part?

A: The Bourns PV36W502C01B00 is supplied in tube packaging, compared to the original part which does not specify packaging format. Tube packaging is standard for through-hole trimmer potentiometers and facilitates automated assembly processes.
