Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0805FRE0720R5L is determined by the following critical parameters:

• Resistance Value: Must be 20.5 Ohms (exact match required)
• Package / Case: Must be 0805 (2012 Metric) for mechanical and electrical compatibility
• Composition: Thin film construction maintains performance characteristics
• Operating Temperature Range: Must support -55°C to 155°C minimum
• RoHS Compliance: ROHS3 Compliant status required for regulatory alignment

The substitute part 5-1625868-7 (TE Connectivity Passive Product) meets all critical substitution criteria. While this substitute exhibits superior tolerance (±0.1% vs ±1%) and higher power rating (0.25W vs 0.125W), these represent enhanced specifications that do not compromise compatibility. The identical package, resistance value, and temperature range ensure direct mechanical and electrical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both the RT0805FRE0720R5L and 5-1625868-7 are Active product status components with ROHS3 compliance and MSL 1 rating. Selection between these parts is based on application-specific requirements:

The RT0805FRE0720R5L is suitable for applications where the specified 0.125W power rating and ±1% tolerance are sufficient and cost optimization is prioritized.

The 5-1625868-7 is suitable for applications requiring enhanced performance margins through higher power rating (0.25W), tighter tolerance (±0.1%), and lower temperature coefficient (±25ppm/°C). The marginal height difference (0.026" vs 0.024") remains within standard PCB assembly tolerances for 0805 packages.

Both parts maintain identical mechanical footprint compatibility and regulatory compliance status, enabling direct substitution within the specified operating temperature range of -55°C to 155°C.

Frequently Asked Questions (FAQ)

Q: Can 5-1625868-7 be used as a direct replacement for RT0805FRE0720R5L?

A: Yes. Both parts share identical resistance value (20.5 Ohms), package (0805), composition (thin film), operating temperature range (-55°C to 155°C), and RoHS compliance status. The substitute exhibits superior tolerance and power rating, which do not compromise compatibility.

Q: What is the significance of the tolerance difference (±1% vs ±0.1%)?

A: Tolerance defines the acceptable resistance variation from the nominal 20.5 Ohm value. The RT0805FRE0720R5L allows ±0.205 Ohm variance, while 5-1625868-7 allows ±0.0205 Ohm variance. Applications requiring tighter resistance control benefit from the substitute part.

Q: Does the height difference (0.024" vs 0.026") affect PCB assembly?

A: No. The 0.002" (0.05mm) height variance is within standard PCB assembly tolerances for 0805 packages and does not impact reflow soldering, component placement, or clearance requirements.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both parts operate across -55°C to 155°C. The substitute exhibits a lower temperature coefficient (±25ppm/°C vs ±50ppm/°C), resulting in improved resistance stability across temperature variations.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. Both parts carry this classification.
