Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3262W-1-104 are classified based on electrical and mechanical parameter alignment:

Direct Manufacturer Substitute (Same Manufacturer): The 3262W-1-104LF is manufactured by Bourns Inc. and shares identical electrical specifications (100 kOhms, 0.25W, ±10% tolerance, ±100ppm/°C, 12-turn cermet) and mechanical form factor. The primary distinction is RoHS compliance status: the 3262W-1-104LF is ROHS3 compliant, whereas the 3262W-1-104 is RoHS non-compliant.

Cross-Manufacturer Substitutes (Equivalent Specifications): The 64WR100KLF and 64YR100KLF, manufactured by TT Electronics/BI Technologies, provide electrical equivalence across all critical parameters: 100 kOhms resistance, 0.25W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, 12-turn adjustment, cermet resistive material, and PC pin through-hole termination. Minor mechanical variation exists in face dimension (0.250" x 0.165" versus 0.250" x 0.170"), representing a 0.13mm reduction in height. Both TT Electronics parts are RoHS compliant and carry MSL 1 (Unlimited) rating.

Substitution eligibility is determined by matching resistance value, power rating, tolerance, temperature coefficient, number of turns, adjustment type, resistive material, mounting type, termination style, and package form factor.

Parameter Comparison

Engineering Selection Recommendations

3262W-1-104LF is the direct equivalent from Bourns Inc., maintaining identical mechanical and electrical specifications while providing ROHS3 compliance. Selection of this part is appropriate for applications requiring regulatory compliance with RoHS directives and continuity within the Bourns Trimpot® 3262 sealed series.

64WR100KLF and 64YR100KLF provide cross-manufacturer equivalence with full electrical parameter matching. Both parts are RoHS compliant and REACH unaffected, offering regulatory advantages over the original 3262W-1-104. The 64YR100KLF offers higher inventory availability (4492 pcs) compared to 64WR100KLF (2100 pcs). Minor mechanical variation in face height (0.165" versus 0.170") must be evaluated against PCB layout constraints and mechanical clearance requirements. Both TT Electronics parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage and handling.

Selection between Bourns and TT Electronics substitutes depends on supply chain requirements, regulatory compliance mandates, and mechanical fit validation within the target application.

Frequently Asked Questions (FAQ)

Q: Can the 3262W-1-104LF be used as a direct replacement for the 3262W-1-104?

A: Yes. The 3262W-1-104LF is electrically and mechanically identical to the 3262W-1-104, with the primary difference being ROHS3 compliance status. Both parts share the same 100 kOhms resistance, 0.25W power rating, 12-turn cermet construction, and 0.250" x 0.170" face dimension. The LF variant is suitable for applications requiring RoHS compliance.

Q: What is the significance of the face dimension difference between Bourns and TT Electronics parts?

A: The Bourns 3262W-1-104 and 3262W-1-104LF have a face dimension of 0.250" x 0.170" (6.35mm x 4.32mm), while the TT Electronics 64WR100KLF and 64YR100KLF measure 0.250" x 0.165" (6.35mm x 4.19mm). The height difference is 0.13mm. This variation must be evaluated against PCB layout, mounting hole spacing, and mechanical clearance requirements to ensure proper fit within the target assembly.

Q: Are the TT Electronics 64WR100KLF and 64YR100KLF interchangeable?

A: Yes. Both parts are electrically and mechanically identical, sharing the same 100 kOhms resistance, 0.25W power rating, 12-turn cermet construction, and 0.250" x 0.165" face dimension. Selection between them is based on inventory availability and supply chain considerations. The 64YR100KLF has higher stock availability (4492 pcs versus 2100 pcs).

Q: What compliance differences exist between the substitute parts?

A: The 3262W-1-104 is RoHS non-compliant and REACH affected. The 3262W-1-104LF is ROHS3 compliant and REACH affected. The 64WR100KLF and 64YR100KLF are both RoHS compliant and REACH unaffected. Applications subject to RoHS or REACH regulatory requirements should specify the 3262W-1-104LF, 64WR100KLF, or 64YR100KLF accordingly.

Q: Does moisture sensitivity affect component handling for any of these parts?

A: The Bourns 3262W-1-104 and 3262W-1-104LF have MSL ratings listed as Not Applicable, indicating no moisture sensitivity restrictions. The TT Electronics 64WR100KLF and 64YR100KLF carry MSL 1 (Unlimited) ratings, also indicating no moisture sensitivity restrictions. All four parts can be stored and handled without special moisture control measures.

Q: What electrical parameters must match for substitution eligibility?

A: Substitution requires matching of resistance value (100 kOhms), power rating (0.25W), tolerance (±10%), temperature coefficient (±100ppm/°C), number of turns (12), adjustment type (top adjustment), resistive material (cermet), mounting type (through hole), and termination style (PC pins). All listed substitute parts meet these criteria.
