Key Parameters

Substitute Part Grouping Explanation

The 3266Y-1-103LF qualifies as a direct substitute based on matching electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Resistance value: 10 kOhms (identical)
• Power rating: 0.25W (identical)
• Tolerance: ±10% (identical)
• Number of turns: 12 (identical)
• Adjustment type: Top Adjustment (identical)
• Resistive material: Cermet (identical)
• Mounting type: Through Hole (identical)
• Termination style: PC Pins (identical)
• RoHS compliance: ROHS3 Compliant (identical)

Physical dimensions show minor variation within acceptable tolerance for PC pin through-hole mounting applications. The substitute part operates within the same electrical performance envelope and maintains compatibility with existing PCB layouts designed for the original component.

Parameter Comparison

Engineering Selection Recommendations

The 3266Y-1-103LF is the qualified substitute for the obsolete PV37Y103C01B00. Selection is based on:

• Identical electrical specifications across all critical parameters
• Active product status ensuring long-term availability and supply chain continuity
• ROHS3 compliance maintained for regulatory requirements
• Cermet construction and 12-turn adjustment mechanism preserved
• PC pin termination compatible with existing through-hole PCB designs

The substitute part exhibits a lower temperature coefficient (±100ppm/°C versus ±150ppm/°C), which represents improved thermal stability. Minor dimensional variations fall within acceptable tolerances for PC pin mounting applications and do not affect functional performance or PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 3266Y-1-103LF be used as a direct replacement for the PV37Y103C01B00?

A: Yes. Both parts share identical resistance, power rating, tolerance, number of turns, adjustment type, resistive material, mounting type, and termination style. The substitute maintains full electrical and mechanical compatibility.

Q: What is the significance of the temperature coefficient difference?

A: The substitute part has a lower temperature coefficient (±100ppm/°C versus ±150ppm/°C), indicating improved resistance stability across temperature variations. This represents a performance enhancement rather than a limitation.

Q: Are there packaging differences between these parts?

A: The original part is specified with "-" packaging, while the substitute is supplied in Tube packaging. Both are suitable for through-hole assembly processes.

Q: Does the product status change affect compatibility?

A: No. The change from Obsolete to Active status improves procurement reliability and supply availability. Electrical and mechanical specifications remain unchanged.

Q: Are both parts compliant with current regulations?

A: Both parts are ROHS3 compliant. The substitute is REACH Affected while the original is REACH Unaffected; however, both meet current regulatory requirements for electronic component use.

Q: What are the physical dimension tolerances?

A: Face dimensions show minor variation (0.252" x 0.157" versus 0.250" x 0.170"). These differences are within acceptable tolerances for PC pin through-hole mounting and do not affect PCB layout compatibility or functional performance.
