Substitute Part Grouping Explanation

Substitution eligibility for the DSC6101CE2A-000.0000 is determined by strict equivalence across the following critical parameters:

Base Resonator Type: MEMS
Oscillator Type: XO (Standard)
Programmable Configuration: Blank (User Must Program)
Frequency Range: 1 MHz ~ 100 MHz
Output Logic: CMOS
Supply Voltage Range: 1.71V ~ 3.63V
Operating Temperature Range: -20°C ~ 70°C
Package / Case: 4-SMD, No Lead
Physical Dimensions: 0.126" L x 0.098" W (3.20mm x 2.50mm)

Engineering Selection Recommendations

All substitute parts maintain full electrical and mechanical compatibility with the DSC6101CE2A-000.0000. Selection between equivalent parts should be based on frequency stability requirements:

For applications requiring ±25ppm frequency stability, DSC6101CE2A-000.0000 and DSC6102CE2A-000.0000 are direct equivalents.

For applications tolerating ±50ppm frequency stability, DSC6101CE1A-000.0000 and DSC6102CE1A-000.0000 are functionally equivalent alternatives.

All parts carry AEC-Q100 automotive-grade qualification and ROHS3 compliance, ensuring suitability for regulated environments. MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can DSC6101CE1A-000.0000 or DSC6102CE1A-000.0000 be used as direct replacements for DSC6101CE2A-000.0000?

A: These parts are functionally equivalent in all parameters except frequency stability tolerance. DSC6101CE1A-000.0000 and DSC6102CE1A-000.0000 specify ±50ppm stability versus ±25ppm for the DSC6101CE2A-000.0000. Substitution is valid only if the application circuit design accommodates the wider tolerance band.

Q: Are all substitute parts identical in physical dimensions and mounting requirements?

A: Yes. All four parts share identical package specifications: 4-SMD No Lead, 3.20mm x 2.50mm footprint, and 0.90mm maximum seated height. PCB layout and reflow profiles are interchangeable.

Q: What is the significance of the CE1A versus CE2A designation in the part number?

A: The CE1A and CE2A suffixes denote frequency stability grade. CE2A parts guarantee ±25ppm stability, while CE1A parts guarantee ±50ppm stability. All other electrical and mechanical characteristics remain identical.

Q: Are these parts suitable for automotive applications?

A: Yes. All parts carry AEC-Q100 qualification, meeting automotive-grade reliability and testing standards.

Q: What is the impact of the obsolete product status on substitution?

A: Obsolete status indicates these parts are no longer manufactured. Substitution between the four equivalent part numbers listed extends component availability from existing inventory. For long-term production requirements, consultation with Microchip Technology regarding active replacement families in the DSC61XX series is recommended.
