DSC1001AE2-100.0000 Equivalent & Substitute Parts

Part Overview

The DSC1001AE2-100.0000 is a 100 MHz MEMS-based crystal oscillator manufactured by Microchip Technology. This CMOS oscillator operates across a 1.8V to 3.3V supply range and features integrated standby (power down) functionality. The device is housed in a 4-VDFN exposed pad surface mount package with dimensions of 7.00mm × 5.00mm and a maximum seated height of 0.90mm. The part maintains an active product status with AEC-Q100 automotive-grade qualification and full RoHS3 compliance. Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and regulatory compliance can be maintained across different packaging or temperature rating configurations.

Substitute Part Grouping Explanation

Substitution eligibility for the DSC1001AE2-100.0000 is determined by strict equivalence across the following critical parameters:

• Frequency: 100 MHz (exact match required)
• Output Type: CMOS (exact match required)
• Supply Voltage Range: 1.8V ~ 3.3V (exact match required)
• Frequency Stability: ±25ppm (exact match required)
• Current Supply (Max): 8.7mA (exact match required)
• Current Supply (Disable): 15µA (exact match required)
• Package Type: 4-VDFN Exposed Pad (exact match required)
• Package Dimensions: 7.00mm × 5.00mm (exact match required)
• Height (Max): 0.90mm (exact match required)
• Base Resonator: MEMS (exact match required)
• Function: Standby (Power Down) (exact match required)
• AEC-Q100 Qualification: Required for automotive applications
• RoHS3 Compliance: Required for regulatory adherence

Variations permitted in substitute parts include operating temperature range, packaging format (tube vs. alternative), and inventory availability, provided all electrical and mechanical specifications remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both the DSC1001AE2-100.0000 and DSC1001AI2-100.0000 maintain active product status with identical electrical specifications, mechanical compatibility, and regulatory certifications. Selection between these parts is determined by application-specific requirements:

The DSC1001AE2-100.0000 operates within a -20°C to 70°C temperature range, suitable for commercial and light industrial applications with moderate thermal environments.

The DSC1001AI2-100.0000 extends the operating temperature range to -40°C to 85°C, accommodating automotive and industrial applications requiring enhanced thermal performance. This extended range aligns with AEC-Q100 automotive qualification requirements for wider environmental conditions.

Both parts carry identical AEC-Q100 ratings, RoHS3 compliance, and MSL Level 1 moisture sensitivity ratings. Packaging format differs (standard vs. tube), which may influence procurement and handling procedures but does not affect electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can DSC1001AI2-100.0000 replace DSC1001AE2-100.0000 in existing designs?

A: Yes. Both parts share identical electrical specifications (100 MHz frequency, ±25ppm stability, 1.8V–3.3V supply, 8.7mA max current), mechanical dimensions (7.00mm × 5.00mm, 0.90mm height), and package type (4-VDFN exposed pad). The DSC1001AI2-100.0000 provides an extended operating temperature range (-40°C to 85°C vs. -20°C to 70°C), making it suitable for broader thermal environments without design modification.

Q: What is the difference between these two parts?

A: The primary difference is the operating temperature range. DSC1001AE2-100.0000 operates from -20°C to 70°C, while DSC1001AI2-100.0000 operates from -40°C to 85°C. Secondary differences include packaging format (standard vs. tube) and inventory availability. All other specifications—frequency, voltage supply, current consumption, package dimensions, and certifications—are identical.

Q: Are both parts AEC-Q100 qualified?

A: Yes. Both DSC1001AE2-100.0000 and DSC1001AI2-100.0000 carry AEC-Q100 automotive-grade qualification, making them suitable for automotive and high-reliability applications.

Q: Do these parts have the same RoHS and REACH compliance status?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: What does MSL Level 1 mean for these oscillators?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life without moisture bake-out requirements. Both parts can be stored indefinitely under standard conditions without special moisture control procedures.

Q: Can I use these parts interchangeably in PCB designs?

A: Yes. Both parts use identical 4-VDFN exposed pad packages with matching footprints (7.00mm × 5.00mm, 0.90mm height). PCB layouts and solder reflow profiles require no modification for substitution.

Q: Which part should I select for automotive applications?

A: Both parts are AEC-Q100 qualified for automotive use. Select DSC1001AI2-100.0000 if your application requires operation below -20°C or above 70°C. Otherwise, either part meets automotive requirements.
