ECS-100-S-19A-TR Crystal Equivalent & Substitute Parts

Part Overview

The ECS-100-S-19A-TR is a 10 MHz fundamental mode crystal oscillator in a 2-SMD, No Lead surface mount package. This Active product is designed for applications requiring precise frequency generation with ±30ppm tolerance. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility allow direct replacement in circuit designs, particularly when packaging format or inventory availability differs from the primary part number.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECS-100-S-19A-TR is determined by the following critical parameters:

• Frequency Match: 10 MHz (exact)
• Frequency Tolerance: ±30ppm (exact)
• Operating Mode: Fundamental (exact)
• Load Capacitance Type: Series (exact)
• Package / Case: 2-SMD, No Lead (exact)
• Mounting Type: Surface Mount (exact)
• Operating Temperature Range: -10°C ~ 70°C (exact)
• Compliance Standards: ROHS3 Compliant, MSL 1

The ECS-100-S-20A-TR meets all substitution criteria. Variations in ESR (80 Ohms vs. 60 Ohms), physical dimensions, and packaging format (Cut Tape vs. Tape & Reel) do not preclude substitution when electrical specifications remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both ECS-100-S-19A-TR and ECS-100-S-20A-TR are Active products with ROHS3 compliance and MSL 1 rating. Selection between these parts is based on:

• Electrical Equivalence: Both parts deliver identical frequency, tolerance, stability, and operating mode specifications. ESR variation (80 Ohms vs. 60 Ohms) reflects design differences within the same product category and does not affect substitution eligibility.
• Physical Compatibility: The ECS-100-S-20A-TR occupies a smaller footprint (7.00mm x 5.00mm vs. 11.00mm x 5.00mm) and lower profile (1.70mm vs. 2.00mm). PCB layout constraints may favor the compact ECS-100-S-20A-TR.
• Packaging Availability: ECS-100-S-20A-TR is available in Tape & Reel format with higher inventory (6654 Pcs) compared to ECS-100-S-19A-TR in Cut Tape format (1575 Pcs). Packaging selection depends on assembly process requirements and volume needs.

Frequently Asked Questions (FAQ)

Q: Can ECS-100-S-20A-TR replace ECS-100-S-19A-TR in existing designs?

A: Yes. Both parts share identical electrical specifications for frequency (10 MHz), tolerance (±30ppm), stability (±50ppm), operating mode (Fundamental), and load capacitance type (Series). The smaller physical dimensions of ECS-100-S-20A-TR may require PCB layout verification to confirm clearance compatibility.

Q: What is the significance of the ESR difference (80 Ohms vs. 60 Ohms)?

A: ESR variation reflects internal design differences between product series (ECX-19A vs. CSM-8A). Both values fall within acceptable ranges for 10 MHz crystal oscillators and do not prevent substitution when all other electrical parameters match.

Q: Does packaging format (Cut Tape vs. Tape & Reel) affect electrical performance?

A: No. Packaging format is a logistics and assembly consideration only. Both formats contain identical components with equivalent electrical characteristics. Selection depends on assembly equipment compatibility and volume requirements.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both ECS-100-S-19A-TR and ECS-100-S-20A-TR operate across -10°C ~ 70°C with identical frequency stability specifications.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 Compliant, REACH Unaffected, and classified as MSL 1 (Unlimited moisture sensitivity level). Both carry EAR99 export classification and HTSUS code 8541.60.0050.
