Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ECS-200-8-37-CWN-TR are qualified based on the following critical parameters:

• Frequency: 20 MHz (exact match required)
• Frequency Tolerance: ±10ppm (exact match required)
• ESR: 100 Ohms (exact match required)
• Operating Mode: Fundamental (exact match required)
• Operating Temperature Range: -40°C to 85°C (exact match required)
• Package / Case: 4-SMD, No Lead (exact match required)
• Size / Dimension: 0.079" L x 0.063" W / 2.00mm x 1.60mm (exact match required)
• Mounting Type: Surface Mount (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• MSL: 1 (Unlimited) (exact match required)

Load Capacitance variance within the same frequency and tolerance specification does not disqualify substitution when circuit design accommodates the load capacitance difference. Substitute parts identified below meet all critical electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance. Selection between ECS-200-8-37-CWN-TR, ECS-200-10-37-CWN-TR, and 402F2001XIAR is determined by load capacitance requirements in the target circuit design. The primary difference among these parts is load capacitance: 8pF for ECS-200-8-37-CWN-TR versus 10pF for both ECS-200-10-37-CWN-TR and 402F2001XIAR. Circuit design must specify the required load capacitance value to ensure proper frequency stability and oscillation characteristics. All parts share identical frequency, tolerance, ESR, temperature range, package, and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can ECS-200-10-37-CWN-TR replace ECS-200-8-37-CWN-TR directly?

A: Direct replacement depends on circuit load capacitance specification. Both parts operate at 20 MHz with ±10ppm tolerance and 100 Ohms ESR. The load capacitance difference (8pF vs. 10pF) must be accommodated by circuit design. Verify the target circuit's load capacitance requirement before substitution.

Q: What is the difference between ECS Inc. and CTS-Frequency Controls parts?

A: Both manufacturers provide 20 MHz crystals with identical electrical specifications (frequency, tolerance, ESR, temperature range) and mechanical compatibility (4-SMD, No Lead package, 2.00mm x 1.60mm). Selection is based on load capacitance requirement and supply chain availability.

Q: Are all substitute parts in the same package?

A: Yes. All listed parts use 4-SMD, No Lead surface mount package with dimensions 0.079" L x 0.063" W (2.00mm x 1.60mm) and maximum seated height of 0.022" (0.55mm). PCB footprint compatibility is maintained across all substitutes.

Q: Do all parts meet the same compliance standards?

A: Yes. All parts are ROHS3 Compliant, REACH Unaffected, and classified as EAR99 with HTSUS code 8541.60.0050. MSL rating is 1 (Unlimited) for all parts, indicating no moisture sensitivity restrictions.

Q: What determines substitution eligibility?

A: Substitution is based on matching frequency (20 MHz), frequency tolerance (±10ppm), ESR (100 Ohms), operating mode (Fundamental), temperature range (-40°C to 85°C), package type (4-SMD, No Lead), physical dimensions (2.00mm x 1.60mm), and compliance certifications (ROHS3). Load capacitance may vary if circuit design accommodates the difference.
