Parameter Comparison

Engineering Selection Recommendations

Both the ECS-PEC33-1250-BN and ECS-PEC25-1250-B-N are active production parts from ECS Inc. with identical RoHS3 compliance and REACH unaffected status. Selection between these parts depends on system voltage supply requirements and packaging format availability.

The ECS-PEC33-1250-BN operates at 3.3V supply voltage and is supplied in Tape & Reel packaging format, suitable for high-volume automated assembly operations.

The ECS-PEC25-1250-B-N operates at 2.5V supply voltage and is supplied in Cut Tape packaging format. This part is applicable only when the system design specifies 2.5V supply voltage operation. The Cut Tape packaging format is suitable for lower-volume or manual assembly processes.

Both parts share identical electrical performance characteristics including 125 MHz frequency, PECL output, ±50ppm frequency stability, and -40°C to 85°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can the ECS-PEC25-1250-B-N be used as a direct replacement for the ECS-PEC33-1250-BN?

A: The ECS-PEC25-1250-B-N is electrically and mechanically compatible with the ECS-PEC33-1250-BN only when the system power supply is 2.5V. The substitute part operates at a different supply voltage and is not suitable for 3.3V supply applications.

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

A: Tape & Reel (TR) packaging is used for high-volume automated assembly with continuous reel feeding. Cut Tape (CT) packaging is supplied as individual tape segments and is typically used for lower-volume or manual assembly operations.

Q: Are both parts RoHS compliant?

A: Yes, both the ECS-PEC33-1250-BN and ECS-PEC25-1250-B-N are ROHS3 compliant and REACH unaffected.

Q: Do both parts have the same physical dimensions?

A: Yes, both parts have identical package dimensions of 0.276" L x 0.197" W (7.00mm x 5.00mm) with a maximum seated height of 0.067" (1.70mm).

Q: What is the frequency stability specification for both parts?

A: Both parts have a frequency stability of ±50ppm across the operating temperature range of -40°C to 85°C.
