Substitute Part Grouping Explanation

Substitute parts for the ECS-PEC33-1000-BN are identified based on strict equivalence of critical electrical and mechanical parameters. The following parameters must remain constant or within allowable tolerances for substitution:

• Frequency: 100 MHz (exact match required)
• Output Type: PECL (exact match required)
• Function: Enable/Disable (exact match required)
• Base Resonator: Crystal (exact match required)
• Type: XO (Standard) (exact match required)
• Frequency Stability: ±50ppm (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Package / Case: 6-SMD, No Lead (exact match required)
• Physical Dimensions: 0.276" L x 0.197" W (7.00mm x 5.00mm) (exact match required)
• Height - Seated (Max): 0.067" (1.70mm) (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The ECS-PEC25-1000-B-N qualifies as a substitute part. While the supply voltage differs (2.5V versus 3.3V), this parameter variation is within the allowed electrical specification range for this product category and does not compromise functional equivalence when the receiving circuit is designed to operate at the lower voltage level.

Parameter Comparison

Engineering Selection Recommendations

Both the ECS-PEC33-1000-BN and ECS-PEC25-1000-B-N are Active products manufactured by ECS Inc. and maintain full compliance with ROHS3 and REACH requirements. Selection between these parts is determined by circuit supply voltage requirements. The ECS-PEC33-1000-BN operates at 3.3V supply voltage, while the ECS-PEC25-1000-B-N operates at 2.5V supply voltage. Both parts share identical frequency output (100 MHz), PECL logic levels, Enable/Disable functionality, frequency stability (±50ppm), operating temperature range (-40°C ~ 85°C), and physical package specifications (6-SMD, No Lead; 7.00mm x 5.00mm x 1.70mm maximum height). Packaging differs between Tape & Reel (TR) for the main part and Cut Tape (CT) for the substitute, which may affect procurement and assembly workflow considerations.

Frequently Asked Questions (FAQ)

Q: Can the ECS-PEC25-1000-B-N replace the ECS-PEC33-1000-BN in all applications?

A: The ECS-PEC25-1000-B-N is electrically and mechanically equivalent to the ECS-PEC33-1000-BN with one critical difference: supply voltage. The substitute operates at 2.5V while the main part operates at 3.3V. Substitution is valid only when the receiving circuit is designed to operate at 2.5V supply voltage. Circuits designed exclusively for 3.3V operation require the ECS-PEC33-1000-BN.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts share identical package specifications: 6-SMD, No Lead case style with dimensions of 0.276" L x 0.197" W (7.00mm x 5.00mm) and maximum seated height of 0.067" (1.70mm). PCB layout and assembly processes are interchangeable.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel packaging supplies components on continuous tape wound on reels, suitable for high-volume automated assembly. Cut Tape packaging supplies components on tape segments cut to specific lengths, typically used for lower-volume orders or manual assembly. Both packaging types contain identical components; the difference is in delivery format and handling.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the ECS-PEC33-1000-BN and ECS-PEC25-1000-B-N are ROHS3 Compliant, REACH Unaffected, and carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Q: What is the frequency stability specification, and does it apply to both parts?

A: Both parts maintain frequency stability of ±50ppm across the operating temperature range of -40°C ~ 85°C. This specification defines the maximum frequency deviation from the nominal 100 MHz center frequency under specified environmental conditions.

Q: Are the Enable/Disable current specifications the same?

A: Yes. Both parts draw a maximum of 90mA during normal operation and 30µA maximum during disable mode, providing identical power management characteristics.
