ECS-100 XO (Standard), TTL output, 4 MHz, ±100ppm, 5V, 14-DIP 4-lead metal can package, bulk, through-hole.","salesMarkdown":"## Standard TTL XO at 4 MHz — fit and sourcing posture The ECS-100A-040 is a standard TTL-output crystal oscillator in the ECS-100 series — a 4 MHz clock source in a 14-lead metal can package rated for 5 V supply with ±100 ppm frequency stability. At 0°C to 70°C commercial temperature grade it suits indoor control-board and instrumentation applications where the TTL interface and wide operating margin are the design drivers. Peak supply draw is 15 mA, so the local LDO or rail regulators need to budget accordingly — that is the idle current floor before the output loads the line. ## Through-hole footprint and legacy assembly fit The 14-DIP, 4-lead full-size metal can mounts through-hole with a 0.821 by 0.520 inch footprint (20.86 mm by 13.20 mm) and seated height of 0.200 inch (5.08 mm). That is the classic through-hole oscillator pinout — pin 1 is typically the output, pins 4 and 8 are ground, and pin 14 is VCC, but the datasheet confirmation is the final word before the layout is committed. Bulk packaging means it ships as loose units; tape-and-reel is not offered in this series, so automated pick-and-place is not the target assembly flow. ## Active lifecycle and availability The ECS-100 series is a long-run through-hole oscillator family, so for a new design the same family footprint is available across the frequency range, though pinout and supply requirements must be verified for any frequency variant before substituting.","metaTitle":"ECS-100A-040 TTL Oscillator 4 MHz ±100ppm 5V","metaDescription":"ECS Inc.
