Mandatory Matching Parameters:

• Frequency: 36.0000 MHz
• Frequency Stability: ±50ppm
• Load Capacitance: 20pF
• Operating Mode: Fundamental
• Operating Temperature Range: -20°C to 70°C
• Package / Case: 4-SMD, No Lead
• Physical Dimensions: 3.20mm x 2.50mm
• Height - Seated (Max): 0.80mm
• Mounting Type: Surface Mount

Allowed Variation Parameters:

• ESR (Equivalent Series Resistance): Variation permitted within component design specifications
• Packaging Format: Tape & Reel (TR) or Cut Tape (CT) formats are interchangeable for equivalent parts
• Manufacturer: Different manufacturers acceptable if all electrical and mechanical parameters match

The ECS-360-20-33-TR meets all mandatory matching criteria and is classified as an equivalent substitute part.

Engineering Selection Recommendations

Primary Part: 7M-36.000MBBK-T

The 7M-36.000MBBK-T remains the specified component when Tape & Reel packaging is required for automated assembly processes. This part is active in production with RoHS compliance and unlimited moisture sensitivity rating, suitable for standard manufacturing environments.

Substitute Part: ECS-360-20-33-TR

The ECS-360-20-33-TR is an equivalent substitute when Cut Tape packaging is acceptable or when supply chain requirements necessitate alternative sourcing. This part maintains all critical electrical parameters and physical dimensions. The lower ESR value (40 Ohms versus 60 Ohms) represents a design variation within acceptable crystal oscillator specifications and does not affect functional compatibility in applications designed for the 20pF load capacitance specification. Both parts carry active product status and full compliance certifications (RoHS and REACH unaffected).

Selection between these parts is determined by packaging format availability and procurement requirements, not by electrical performance differences.

Frequently Asked Questions (FAQ)

Q: Can the ECS-360-20-33-TR replace the 7M-36.000MBBK-T in my circuit design?

A: Yes. The ECS-360-20-33-TR is an equivalent substitute. Both parts operate at 36.0000 MHz with ±50ppm stability, 20pF load capacitance, and identical physical dimensions. The difference in ESR (40 Ohms versus 60 Ohms) is a design variation that does not affect compatibility with circuits specified for 20pF load capacitance.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging is supplied on continuous tape wound on reels, optimized for high-volume automated assembly. Cut Tape (CT) packaging is supplied as individual segments cut from the tape, suitable for lower-volume applications or manual assembly. Both formats contain identical components.

Q: Are there any compliance differences between these parts?

A: Both parts are RoHS compliant and REACH unaffected. The 7M-36.000MBBK-T carries RoHS Compliant status, while the ECS-360-20-33-TR carries ROHS3 Compliant status. Both meet current regulatory requirements for electronic component manufacturing.

Q: Does the lower ESR of the ECS part affect circuit performance?

A: No. ESR variation between 40 Ohms and 60 Ohms is within normal design tolerance for crystal oscillators in this category. Both values are acceptable for circuits designed to the 20pF load capacitance specification. Circuit performance is determined by frequency accuracy and stability, which are identical between these parts.

Q: Can I mix these parts in the same production batch?

A: Yes, provided your assembly process can accommodate both Tape & Reel and Cut Tape formats. The electrical and mechanical specifications are equivalent, allowing interchangeable use in the same circuit design.

Q: What is the MSL rating and why does it matter?

A: Both parts carry MSL 1 (Unlimited) rating, indicating unlimited shelf life without moisture absorption concerns. This simplifies inventory management and eliminates baking requirements before assembly.
