Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for 32 MHz crystal oscillators is determined by the following critical parameters:

• Frequency Match: 32 MHz (exact match required)
• Frequency Tolerance: ±30ppm (must be maintained or tighter)
• Frequency Stability: ±50ppm (must be maintained or better)
• Operating Temperature Range: -10°C ~ 70°C (must cover or exceed)
• Mounting Type: Surface Mount (mechanical compatibility)
• Package / Case: 2-SMD, No Lead (footprint compatibility)
• Physical Dimensions: 7.00mm x 5.00mm (PCB layout compatibility)
• RoHS & Compliance Status: ROHS3 Compliant (regulatory requirement)

The ECS-320-S-20A-F-TR qualifies as a substitute based on matching all critical parameters. Variations in ESR and operating mode do not preclude substitution when all primary electrical and mechanical specifications align.

Frequently Asked Questions (FAQ)

Q: Can ECS-320-S-20A-F-TR replace ECS-320-S-20A-TR in production?

A: Yes. Both parts share identical frequency (32 MHz), frequency tolerance (±30ppm), frequency stability (±50ppm), operating temperature range (-10°C ~ 70°C), package type (2-SMD, No Lead), and physical dimensions (7.00mm x 5.00mm). The difference in ESR (80 Ohms vs. 40 Ohms) and operating mode (3rd Overtone vs. Fundamental) does not prevent functional substitution when circuit design accommodates these variations.

Q: What is the difference in packaging between these parts?

A: ECS-320-S-20A-TR is supplied in Tape & Reel (TR) format for automated pick-and-place assembly in high-volume production. ECS-320-S-20A-F-TR is supplied in Cut Tape (CT) format for manual or semi-automated assembly in lower-volume applications. Both formats contain the same component.

Q: Are both parts RoHS compliant?

A: Yes. Both ECS-320-S-20A-TR and ECS-320-S-20A-F-TR are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards for electronic components.

Q: What does Moisture Sensitivity Level (MSL) 1 mean?

A: MSL 1 indicates Unlimited shelf life without moisture exposure precautions. Both parts do not require special moisture control during storage or handling.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. Both parts have identical physical dimensions (7.00mm x 5.00mm) and maximum seated height (1.70mm), ensuring compatible PCB footprints and assembly processes.
