DSC1124CE1-100.0000T Equivalent & Substitute Parts

Part Overview

The DSC1124CE1-100.0000T is a 100 MHz MEMS-based XO (Standard) oscillator manufactured by Microchip Technology. It operates across a 2.25V to 3.6V supply range with HCSL output, Enable/Disable functionality, and ±50ppm frequency stability. The device is housed in a 6-SMD, No Lead package measuring 3.20mm × 2.50mm with a maximum seated height of 0.90mm. This part is Active status and ROHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the specified parameter set.

Substitute Part Grouping Explanation

Substitution eligibility for the DSC1124CE1-100.0000T is determined by the following critical parameters:

• Frequency: 100 MHz (exact match required)
• Output Type: HCSL (exact match required)
• Function: Enable/Disable (exact match required)
• Package / Case: 6-SMD, No Lead (exact match required)
• Size / Dimension: 3.20mm × 2.50mm (exact match required)
• Frequency Stability: ±50ppm (exact match required)
• RoHS Status: ROHS3 Compliant (compliance requirement)
• MSL Rating: 1 (Unlimited) (handling requirement)

The NX3241E0100.000000 from Diodes Incorporated meets all critical substitution criteria. While the supply voltage range differs (3.3V fixed versus 2.25V ~ 3.6V range), the operating temperature range extends (-40°C ~ 85°C versus -20°C ~ 70°C), and current consumption specifications vary, these parameters do not disqualify substitution when the primary electrical and mechanical requirements align.

Parameter Comparison

Engineering Selection Recommendations

Both the DSC1124CE1-100.0000T and NX3241E0100.000000 are Active status products with ROHS3 compliance and unlimited moisture sensitivity ratings. Selection between these parts should be based on application-specific requirements:

The DSC1124CE1-100.0000T provides a wider supply voltage operating range (2.25V ~ 3.6V) and lower maximum supply current (42mA), making it suitable for applications requiring flexible voltage input or power-constrained environments.

The NX3241E0100.000000 operates at a fixed 3.3V supply with extended temperature range (-40°C ~ 85°C) and is suitable for applications requiring broader thermal performance. The increased current consumption (70mA maximum) and slightly greater seated height (1.05mm versus 0.90mm) must be evaluated against specific board layout and power budget constraints.

Both parts maintain identical frequency (100 MHz), output type (HCSL), function (Enable/Disable), frequency stability (±50ppm), and physical footprint (3.20mm × 2.50mm), ensuring mechanical and electrical compatibility at the interface level.

Frequently Asked Questions (FAQ)

Q: Can the NX3241E0100.000000 directly replace the DSC1124CE1-100.0000T in all applications?

A: Direct replacement is possible when the application supply voltage is fixed at 3.3V. If the circuit requires operation across the full 2.25V ~ 3.6V range, the NX3241E0100.000000 may not be suitable due to its fixed 3.3V supply requirement.

Q: What is the impact of the different supply current specifications?

A: The DSC1124CE1-100.0000T draws a maximum of 42mA, while the NX3241E0100.000000 draws 70mA. Power supply design and current budgeting must account for this 28mA difference. Disable mode current also differs (22mA versus 40mA).

Q: Are the packages mechanically identical?

A: Both parts use 6-SMD, No Lead packaging with identical footprints (3.20mm × 2.50mm). The seated height differs slightly (0.90mm versus 1.05mm), which may affect clearance in space-constrained designs.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the DSC1124CE1-100.0000T and NX3241E0100.000000 are ROHS3 compliant, REACH unaffected, and carry MSL rating 1 (Unlimited).

Q: What is the difference between MEMS and Crystal resonator types?

A: The DSC1124CE1-100.0000T uses a MEMS resonator, while the NX3241E0100.000000 uses a crystal resonator. Both achieve the same ±50ppm frequency stability specification. MEMS oscillators typically offer better shock and vibration resistance, while crystal oscillators are established in high-volume applications.

Q: Can I use the NX3241E0100.000000 in a -20°C to 70°C application?

A: Yes. The NX3241E0100.000000 operates across -40°C ~ 85°C, which encompasses the -20°C ~ 70°C range. Extended temperature capability does not prevent operation within a narrower range.
