Substitute Part Grouping Explanation

Substitution of the Crystek Corporation 016929 is permissible with the ECS Inc. ECS-120-20-30B-TR based on the following critical parameters:

Matching Parameters (Substitution Basis):

• Frequency: 12 MHz (identical)
• Operating Mode: Fundamental (identical)
• Mounting Type: Surface Mount (identical)
• Package / Case: 4-SMD, No Lead (identical)
• Size / Dimension: 0.197" L x 0.126" W (5.00mm x 3.20mm) (identical)
• Packaging: Tape & Reel (TR) (identical)
• RoHS Status: ROHS3 Compliant (identical)
• Moisture Sensitivity Level (MSL): 1 (Unlimited) (identical)
• REACH Status: REACH Unaffected (identical)
• ECCN: EAR99 (identical)
• HTSUS: 8541.60.0050 (identical)

The substitute part maintains electrical and mechanical compatibility through identical frequency specification, operating mode, and physical package dimensions. Both components are surface mount crystals in 4-SMD, No Lead configuration with matching footprint and mounting requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the Crystek Corporation 016929 and ECS Inc. ECS-120-20-30B-TR are Active product status components with identical RoHS3 compliance, REACH unaffected status, and regulatory classifications (ECCN EAR99, HTSUS 8541.60.0050). The substitute part maintains full compliance with environmental and trade regulations applicable to the original component.

Selection between these parts is based on availability, supply chain requirements, and inventory status. Both components satisfy the same regulatory and compliance framework for 12 MHz surface mount crystal applications in 4-SMD, No Lead packaging.

Frequently Asked Questions (FAQ)

Q: Can the ECS ECS-120-20-30B-TR directly replace the Crystek 016929?

A: Yes. Both components share identical frequency (12 MHz), operating mode (Fundamental), mounting type (Surface Mount), and package configuration (4-SMD, No Lead with 5.00mm x 3.20mm dimensions). Physical and electrical compatibility is established through these matching parameters.

Q: Are there differences in compliance or regulatory status between these parts?

A: No. Both components are RoHS3 compliant, REACH unaffected, classified as EAR99, and assigned the same HTSUS code (8541.60.0050). Regulatory and environmental compliance is equivalent.

Q: What is the significance of the 4-SMD, No Lead package?

A: The 4-SMD, No Lead package defines the physical footprint and mounting interface. Both parts use this identical package configuration, ensuring compatibility with the same PCB layout and reflow soldering process.

Q: Are the Tape & Reel packaging specifications identical?

A: Yes. Both components are supplied in Tape & Reel (TR) packaging with MSL rating of 1 (Unlimited), indicating identical moisture handling and storage requirements.

Q: What parameters determine substitution eligibility for 12 MHz surface mount crystals?

A: Substitution is determined by frequency (12 MHz), operating mode (Fundamental), mounting type (Surface Mount), package type (4-SMD, No Lead), and physical dimensions (0.197" L x 0.126" W / 5.00mm x 3.20mm). Matching these parameters ensures mechanical and electrical compatibility.
