Key Parameters

Substitute Part Grouping Explanation

Substitution is determined by matching the fundamental electrical and mechanical characteristics required for the Clock/Timing category. The allowed key parameters for substitution include: type (Jitter Attenuator or Frequency Translator with Jitter Attenuation), PLL functionality, input/output options, number of circuits, supply voltage range, operating temperature range, mounting type, and package class. Substitute part consideration is strictly limited to these provided parameters.

Parameter Comparison

Engineering Selection Recommendations

The main part, 810251AGILF-EXT, is obsolete. Its substitute, 8T49N241-003NLGI, is active and compliant with RoHS3 and REACH regulations. The supply voltage, operating temperature, and mounting type parameters match; ensure inventory and compliance status align with project requirements. Moisture Sensitivity Level differs; compare storage and handling needs directly. Only parameters provided should be used for substitution validation.

Frequently Asked Questions (FAQ)

Q1. What are the primary substitution criteria between 810251AGILF-EXT and 8T49N241-003NLGI?
A1. Substitution is determined by category, supply voltage, operating temperature, PLL functionality, number of circuits, mounting type, and input/output signaling compatibility.

Q2. Is package type an exact match between the main and substitute part?
A2. The main part uses a 16-TSSOP package; the substitute uses a 40-VFQFN package. Both are surface mount, but footprint and pad layout are different and must be verified for mechanical compatibility.

Q3. Are the supply voltages and operating temperature ranges compatible?
A3. Both parts operate at 2.375V ~ 3.465V and -40°C ~ 85°C.

Q4. Does the substitute part support similar input and output signaling?
A4. The substitute part supports a wider input and output signal set in addition to those listed for the main part.

Q5. How does Moisture Sensitivity Level impact selection?
A5. The main part has MSL 1 (Unlimited), while the substitute is rated MSL 3 (168 Hours). Storage and assembly handling require direct comparison based on these values.
