Substitute Part Grouping Explanation

Substitution of the ECS-196-20-23A-TR is based on strict equivalence of electrical and mechanical parameters. The primary substitute part ECS-196-20-23A-EN-TR maintains identical frequency, load capacitance, ESR, package dimensions, and physical form factor. The key differentiator between these parts is packaging format: the main part is supplied in Cut Tape (CT) format, while the substitute is supplied in Tape & Reel (TR) format. Both parts are manufactured by ECS Inc. within the ECX-64A series and carry identical compliance certifications.

Substitution is valid when the following parameters remain constant:

• Frequency: 19.6608 MHz
• Frequency Tolerance: ±30ppm
• Load Capacitance: 20pF
• ESR: 60 Ohms
• Package / Case: 2-SMD, No Lead
• Physical Dimensions: 6.00mm x 4.60mm x 1.10mm (max height)
• Mounting Type: Surface Mount

Parameter Comparison

Engineering Selection Recommendations

Both ECS-196-20-23A-TR and ECS-196-20-23A-EN-TR are active products manufactured by ECS Inc. with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on packaging requirements and operating temperature specifications for the target application.

The ECS-196-20-23A-TR in Cut Tape format is suitable for applications with operating temperatures between -10°C and 70°C. The ECS-196-20-23A-EN-TR in Tape & Reel format extends the operating temperature range to -40°C to 85°C, providing broader thermal performance for demanding environments. All other electrical and mechanical characteristics remain identical between the two part numbers.

Frequently Asked Questions (FAQ)

Q: Can ECS-196-20-23A-EN-TR be used as a direct replacement for ECS-196-20-23A-TR?

A: Yes, provided the application operating temperature range does not exceed -10°C to 70°C. The ECS-196-20-23A-EN-TR supports an extended temperature range of -40°C to 85°C, making it suitable for all applications where the main part is specified. All electrical parameters, frequency specifications, and physical dimensions are identical.

Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging?

A: Cut Tape format provides individual component strips suitable for lower-volume applications and manual assembly processes. Tape & Reel format supplies components on continuous reels optimized for automated pick-and-place assembly equipment. Both formats contain identical components with the same electrical and mechanical specifications.

Q: Are there any compliance or certification differences between these parts?

A: No. Both ECS-196-20-23A-TR and ECS-196-20-23A-EN-TR carry identical ROHS3 compliance, REACH unaffected status, and Moisture Sensitivity Level 1 (Unlimited) ratings.

Q: What determines whether a crystal can be substituted for this part?

A: Substitution requires matching frequency (19.6608 MHz), frequency tolerance (±30ppm), load capacitance (20pF), ESR (60 Ohms), package type (2-SMD, No Lead), and physical dimensions (6.00mm x 4.60mm x 1.10mm max height). Operating temperature range may differ if the application permits.

Q: Can I use a different frequency crystal as a substitute?

A: No. The frequency specification of 19.6608 MHz is application-critical and cannot be altered. Any deviation in frequency will result in circuit malfunction or performance degradation.
