ECS-360-S-20A-F-TR Crystal Equivalent & Substitute Parts

Part Overview

The ECS-360-S-20A-F-TR is a 36 MHz surface mount crystal oscillator manufactured by ECS Inc., classified as a fundamental mode crystal in the CSM-8A series. This component is actively produced and widely used in timing applications requiring precise frequency generation. The part is packaged in Tape & Reel (TR) format with 2-SMD, No Lead configuration and operates across the -10°C to 70°C temperature range. Finding equivalent or substitute parts may be necessary due to supply chain considerations, packaging format requirements, or inventory availability while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECS-360-S-20A-F-TR is determined by the following critical parameters:

Frequency and tolerance specifications must remain constant at 36 MHz with ±30ppm tolerance to ensure circuit timing requirements are met. The package configuration (2-SMD, No Lead) and physical dimensions (7.00mm x 5.00mm x 1.70mm max height) must be identical to maintain PCB layout compatibility and automated assembly feasibility. The operating temperature range (-10°C to 70°C) and RoHS3 compliance status must be preserved. Moisture sensitivity level (MSL 1) ensures handling and storage compatibility with existing supply chain processes.

The ESR (Equivalent Series Resistance) and operating mode (fundamental vs. overtone) are secondary parameters that may vary within acceptable limits depending on circuit design specifications. Packaging format (Tape & Reel vs. Cut Tape) represents a logistical variation that does not affect electrical performance or mechanical fit.

Parameter Comparison

Engineering Selection Recommendations

Both the ECS-360-S-20A-F-TR and ECS-360-S-20A-TR maintain active product status with full ROHS3 compliance and MSL 1 rating, confirming regulatory and environmental compatibility. The primary distinction between these parts is the packaging format (Tape & Reel versus Cut Tape) and secondary electrical parameters (ESR and operating mode).

Selection between these parts should be based on procurement and assembly requirements. The Tape & Reel format (ECS-360-S-20A-F-TR) is optimized for high-volume automated pick-and-place assembly operations. The Cut Tape format (ECS-360-S-20A-TR) accommodates lower-volume production runs or manual assembly workflows. Both parts deliver identical frequency, tolerance, and temperature specifications required for circuit timing functionality.

The difference in ESR (40 Ohms versus 60 Ohms) and operating mode (Fundamental versus 3rd Overtone) must be evaluated against specific circuit design parameters. These variations may affect oscillator startup characteristics and power consumption but do not alter the delivered frequency output or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can ECS-360-S-20A-TR (Cut Tape) be used as a direct replacement for ECS-360-S-20A-F-TR (Tape & Reel)?

A: Yes, from an electrical and mechanical standpoint. Both parts share identical frequency (36 MHz), tolerance (±30ppm), package configuration (2-SMD, No Lead), and physical dimensions (7.00mm x 5.00mm x 1.70mm). The packaging format difference (Cut Tape versus Tape & Reel) affects supply chain logistics and assembly equipment compatibility, not component performance or PCB fit.

Q: What is the significance of the ESR difference (40 Ohms vs. 60 Ohms)?

A: ESR (Equivalent Series Resistance) influences oscillator circuit behavior, including startup time and power consumption. The main part specifies 40 Ohms while the substitute specifies 60 Ohms. Circuit design parameters determine whether this variation is acceptable. Consult circuit design documentation to confirm ESR compatibility requirements.

Q: Does the operating mode difference (Fundamental vs. 3rd Overtone) affect frequency output?

A: No. Both fundamental and 3rd overtone modes deliver the same 36 MHz output frequency. Operating mode affects internal crystal behavior and circuit interaction but not the final frequency delivered to the application. Circuit design specifications determine which mode is appropriate.

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

A: Yes. Both ECS-360-S-20A-F-TR and ECS-360-S-20A-TR operate across -10°C to 70°C, ensuring compatibility with identical thermal requirements.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating, confirming equivalent regulatory and environmental compliance.
