Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0805FRE0718R7L is determined by the following critical parameters:

• Resistance Value: Must be 18.7 Ohms
• Package Type: Must be 0805 (2012 Metric) for mechanical and electrical compatibility
• Composition: Thin film construction ensures performance consistency
• Operating Temperature Range: Must support -55°C to 155°C minimum
• Termination Count: Must have 2 terminations for standard PCB mounting

The substitute part 5-1625868-3 meets all mechanical compatibility requirements and maintains the same resistance value and package footprint. Enhanced specifications in tolerance (±0.1% vs ±1%) and power rating (0.25W vs 0.125W) represent performance improvements that do not compromise compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the RT0805FRE0718R7L and 5-1625868-3 are actively manufactured components with full ROHS3 compliance and unlimited moisture sensitivity rating, making them suitable for standard industrial and commercial applications.

The RT0805FRE0718R7L is the primary specification component and should be used when the ±1% tolerance and ±50ppm/°C temperature coefficient meet application requirements.

The 5-1625868-3 substitute offers enhanced specifications with ±0.1% tolerance and ±25ppm/°C temperature coefficient, making it suitable for applications requiring tighter resistance stability. The doubled power rating (0.25W vs 0.125W) provides additional thermal margin. The maximum seated height difference of 0.002" (0.05mm) is negligible for standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can 5-1625868-3 be used as a direct replacement for RT0805FRE0718R7L?

A: Yes. Both components share identical resistance value (18.7 Ohms), package type (0805), footprint dimensions (2.00mm x 1.25mm), and operating temperature range (-55°C to 155°C). The substitute offers improved tolerance and temperature coefficient specifications.

Q: What is the maximum height difference between these parts?

A: The RT0805FRE0718R7L has a maximum seated height of 0.024" (0.60mm), while the 5-1625868-3 measures 0.026" (0.65mm). This 0.002" (0.05mm) difference is within standard PCB assembly tolerances and does not affect component placement or board clearance in typical applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the RT0805FRE0718R7L and 5-1625868-3 are ROHS3 compliant and carry unlimited moisture sensitivity rating (MSL 1), meeting environmental and reliability standards for industrial applications.

Q: What determines substitution compatibility for 0805 thin film resistors?

A: Mechanical and electrical compatibility is determined by matching resistance value, tolerance class, package type, and operating temperature range. Both components meet these criteria for the 18.7 Ohm specification.
