Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3299Y-1-101 are identified based on matching the following critical parameters: resistance value (100 Ohms), power rating (0.5W), tolerance (±10%), temperature coefficient (±100ppm/°C), number of turns (25), adjustment type (top adjustment), resistive material (cermet), mounting type (through hole), and termination style (PC pins).

Two substitute parts meet these electrical and mechanical criteria:

1. 3299Y-1-101LF — Identical electrical specifications and same series (Trimpot® 3299). Differs in RoHS compliance status (ROHS3 Compliant vs. non-compliant). Physical dimensions match exactly.

2. 3296Y-1-101 — Identical electrical specifications and same manufacturer. Differs in series designation (Trimpot® 3296 vs. 3299) and physical face dimensions (0.375" x 0.190" vs. 0.375" x 0.240").

Parameter Comparison

Engineering Selection Recommendations

3299Y-1-101LF is the direct equivalent for applications requiring RoHS3 compliance. Electrical performance and physical dimensions are identical to the main part. This variant is suitable for designs subject to RoHS regulations or customer compliance mandates.

3296Y-1-101 is electrically equivalent but belongs to the Trimpot® 3296 series with a reduced face height (0.190" vs. 0.240"). This part is applicable only when the smaller profile accommodates PCB layout constraints. Verify mechanical fit before substitution, as the reduced height may affect mounting clearance or adjustment accessibility.

Both substitute parts maintain REACH Affected status and EAR99 export classification consistent with the main part.

Frequently Asked Questions (FAQ)

Q: Can 3299Y-1-101LF replace 3299Y-1-101 in existing designs?

A: Yes. The 3299Y-1-101LF is electrically and mechanically identical. The primary difference is RoHS3 compliance. If your application or supply chain requires RoHS compliance, this part is a direct substitute.

Q: What is the key difference between 3299Y-1-101 and 3296Y-1-101?

A: Both parts have identical electrical specifications (100 Ohms, 0.5W, ±10% tolerance, ±100ppm/°C, 25 turns, cermet, top adjustment). The 3296Y-1-101 has a smaller face dimension (0.190" height vs. 0.240"). Substitution is valid only if the reduced height fits your PCB layout and does not compromise adjustment accessibility.

Q: Are all three parts interchangeable?

A: Electrically, yes. Mechanically, the 3296Y-1-101 requires verification due to its smaller profile. The 3299Y-1-101 and 3299Y-1-101LF are fully interchangeable with no mechanical considerations.

Q: What does the "LF" designation in 3299Y-1-101LF indicate?

A: The "LF" suffix indicates lead-free and RoHS3 compliance. This variant meets environmental and regulatory requirements for restricted substances.

Q: Can I use 3296Y-1-101 if space is limited on my PCB?

A: The 3296Y-1-101 has a smaller face height and may fit tighter layouts. However, verify that the reduced height does not interfere with adjustment tool access or create clearance issues with adjacent components.
