Key Parameters

Substitute Part Grouping Explanation

Substitution of the CRL2010-FW-R056ELF is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Resistance value: 56 mOhms
• Tolerance: ±1%
• Package: 2010 (5025 Metric)
• Composition: Thick Film
• Terminations: 2

Mechanical Compatibility Requirements:

• Physical dimensions: 0.197" L x 0.098" W (5.00mm x 2.50mm)
• Height (Seated Max): 0.028" (0.70mm)

Regulatory & Environmental Requirements:

• RoHS3 Compliance
• MSL 1 (Unlimited)

The substitute part CRM2010-FX-R056ELF meets all mechanical and electrical compatibility criteria. The primary difference is an increased power rating (1W versus 0.75W) and improved temperature coefficient (±100ppm/°C versus ±200ppm/°C), with an extended maximum operating temperature (155°C versus 125°C). These differences represent enhanced performance characteristics within the same package footprint.

Parameter Comparison
