Key Parameters

Substitute Part Grouping Explanation

Substitution for the 3296Z-1-205 is based on strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical specifications for resistance value, power rating, tolerance, temperature coefficient, number of turns, adjustment type, resistive material composition, mounting configuration, termination style, and physical dimensions. The primary distinction between the main part and its substitute relates to RoHS compliance status and lead-free termination processing.

Key parameters determining substitutability:

• Resistance: 2 MOhms (exact match required)
• Power Rating: 0.5W (exact match required)
• Adjustment Mechanism: Side Adjustment, 25-turn (exact match required)
• Physical Form Factor: Rectangular 0.395" x 0.190" (exact match required)
• Termination: PC Pins through-hole (exact match required)

Parameter Comparison

Engineering Selection Recommendations

The 3296Z-1-205LF serves as a direct equivalent to the 3296Z-1-205, with all electrical and mechanical specifications identical. The primary distinction is RoHS3 compliance of the 3296Z-1-205LF variant, which incorporates lead-free termination processing. Selection between these parts should be based on regulatory requirements and compliance mandates applicable to the end application. Both parts maintain active production status and equivalent inventory availability. The REACH Affected designation applies uniformly to both variants.

Frequently Asked Questions (FAQ)

Q: Can the 3296Z-1-205LF be used as a direct replacement for the 3296Z-1-205?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters including resistance, power rating, tolerance, temperature coefficient, adjustment mechanism, and physical dimensions. The difference is RoHS3 compliance in the LF variant.

Q: What does the "LF" suffix indicate in the 3296Z-1-205LF part number?

A: The "LF" designation indicates lead-free termination processing and RoHS3 compliance. The component maintains identical functional and dimensional specifications to the non-LF version.

Q: Are there any compatibility concerns when substituting between these parts?

A: No compatibility concerns exist. Both parts feature identical PC pin through-hole termination, rectangular form factor, and mounting specifications. PCB layout and circuit design remain unchanged.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS3 compliance, specify the 3296Z-1-205LF. For applications without RoHS compliance mandates, either part is functionally equivalent.

Q: Do both parts have the same adjustment characteristics?

A: Yes. Both parts feature identical 25-turn side adjustment mechanisms with cermet resistive material and ±100ppm/°C temperature coefficient.
