Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7M20020003 is determined by the following mandatory parameters:

Electrical Compatibility Requirements:

• Frequency: 20 MHz (exact match required)
• Frequency Stability: ±30ppm (exact match required)
• Load Capacitance: 12pF (exact match required)

Mechanical Compatibility Requirements:

• Package Type: 4-SMD, No Lead (exact match required)
• Mounting Type: Surface Mount (exact match required)

Environmental & Compliance Requirements:

• Operating Temperature Range: -20°C to 70°C (minimum requirement)
• RoHS Status: RoHS Compliant or equivalent
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute parts 8Y-20.000MAAE-T and 8Z-20.000MAAE-T meet all mandatory electrical and mechanical parameters. Differences in physical dimensions, ESR specification, and packaging format (Tape & Reel vs. Cut Tape) do not affect functional substitution capability.

Parameter Comparison

Engineering Selection Recommendations

All three parts—7M20020003, 8Y-20.000MAAE-T, and 8Z-20.000MAAE-T—are Active products from TXC CORPORATION with full RoHS compliance and REACH Unaffected status. Selection between these parts is based on packaging and inventory requirements rather than electrical performance differences.

7M20020003 (Series 7M): Primary specification. Standard packaging format. 754 units in stock.

8Y-20.000MAAE-T (Series 8Y): Functionally equivalent. Supplied in Tape & Reel (TR) format for automated assembly processes. 970 units in stock. Smaller physical footprint (2.00mm x 1.60mm vs. 3.20mm x 2.50mm). Lower profile (0.55mm vs. 0.80mm).

8Z-20.000MAAE-T (Series 8Z): Functionally equivalent. Supplied in Cut Tape (CT) format for manual or semi-automated assembly. 1121 units in stock. Intermediate physical dimensions (2.50mm x 2.00mm). Lower profile (0.55mm vs. 0.80mm).

Selection criteria: Choose based on assembly process requirements (automated vs. manual), available inventory, and PCB layout constraints. All parts deliver identical electrical performance within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can 8Y-20.000MAAE-T replace 7M20020003 in production?

A: Yes. Both parts meet identical electrical specifications (20 MHz, ±30ppm stability, 12pF load capacitance) and package requirements (4-SMD, No Lead, Surface Mount). The 8Y series is supplied in Tape & Reel format, suitable for automated pick-and-place assembly. Physical dimensions are smaller, which may require PCB layout verification.

Q: What is the difference between 8Y-20.000MAAE-T and 8Z-20.000MAAE-T?

A: Both parts are electrically identical. The primary difference is packaging format: 8Y-20.000MAAE-T is supplied in Tape & Reel (TR) for automated assembly, while 8Z-20.000MAAE-T is supplied in Cut Tape (CT) for manual or semi-automated assembly. Physical dimensions also differ slightly (2.00mm x 1.60mm vs. 2.50mm x 2.00mm).

Q: Are there ESR differences between these parts?

A: The 7M20020003 does not specify ESR in the provided data. The 8Y-20.000MAAE-T and 8Z-20.000MAAE-T both specify 100 Ohms ESR. This parameter does not affect substitution eligibility for the stated application requirements.

Q: Do all three parts have the same moisture sensitivity rating?

A: Yes. All three parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

Q: Which part should be selected for space-constrained applications?

A: The 8Y-20.000MAAE-T and 8Z-20.000MAAE-T offer reduced physical dimensions (2.00mm x 1.60mm and 2.50mm x 2.00mm respectively) compared to the 7M20020003 (3.20mm x 2.50mm). Both substitute parts also feature lower profile (0.55mm vs. 0.80mm). Selection between 8Y and 8Z depends on assembly process requirements.

Q: Are all parts RoHS compliant?

A: Yes. The 7M20020003 and 8Z-20.000MAAE-T are RoHS Compliant. The 8Y-20.000MAAE-T is ROHS3 Compliant. All meet current RoHS requirements and are suitable for regulated applications.
