AI Summary	ABLS-12.000MHZ-B4H-T by ABRACON: Crystal, ABLS, 12 MHz, 30 ppm, 35 ppm, 18 pF.	The ABLS-12.000MHZ-D4Y-T is an exact ordering-code variant within the same Abracon ABLS series. It provides identical 12 MHz frequency, 18pF load capacitance, 50Ω max ESR, and ±30ppm tolerance, while extending the operating temperature range to -40°C ~ +85°C with tighter ±30ppm frequency stability. It serves as an active, pin-compatible drop-in alternative. Wider operating temperature range: -40°C to +85°C vs -20°C to +70°C Better frequency stability over temperature: ±30ppm vs ±35ppm Pin-compatible drop-in replacement in same HC-49/US SMD package	The ECS-120-18-5G3XDS-TR is a second-source 12 MHz crystal in an HC-49/US SMD package. It matches the original's 18pF load capacitance, 50Ω max ESR, and ±30ppm initial tolerance while extending temperature capability to +125°C. It features a 3-lead variant package with an optional ground lead. Wider operating temperature range: -40°C to +125°C vs -20°C to +70°C Same 12 MHz frequency, 18pF load capacitance, ±30ppm tolerance, and 50Ω max ESR Wider frequency stability tolerance (±100ppm over extended -40°C to +125°C range) 3-lead package variant requires checking center pad board clearance/grounding

You searched one part. Parter watches your whole BOM.

All your BOM, at once
Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.
Hear about problems before they hit production
Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.
Qualified replacements in minutes, not days
Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
