Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0805FRE0712R7L is determined by the following critical parameters:

• Resistance Value: Must be 12.7 Ohms
• Package Format: Must be 0805 (2012 Metric)
• Composition: Must be Thin Film
• Operating Temperature Range: Must support -55°C to 155°C minimum
• Compliance: Must maintain RoHS3 compliance and MSL Level 1 rating
• Physical Dimensions: Must conform to 0.079" L x 0.049" W (2.00mm x 1.25mm) with compatible height specifications

The substitute part 3-1625868-7 (TE Connectivity Passive Product) meets all mandatory substitution criteria. While this substitute offers improved tolerance (±0.1% versus ±1%) and higher power rating (0.25W versus 0.125W), these represent performance enhancements rather than deviations from the core electrical and mechanical requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the RT0805FRE0712R7L and 3-1625868-7 maintain Active product status and full RoHS3 compliance with MSL Level 1 ratings. The substitute part 3-1625868-7 is suitable for applications requiring the same 12.7 Ohm resistance value in the 0805 package format. The TE Connectivity part offers tighter tolerance specification (±0.1%) and higher power dissipation capability (0.25W), which may provide performance advantages in precision circuits or higher thermal environments. Physical compatibility is confirmed through identical footprint dimensions and compatible height specifications. Selection between these parts should be based on application-specific tolerance and power requirements.

Frequently Asked Questions (FAQ)

Q: Can the 3-1625868-7 directly replace the RT0805FRE0712R7L in existing designs?

A: Yes. Both parts share identical resistance values (12.7 Ohms), package format (0805), composition (Thin Film), operating temperature range (-55°C to 155°C), and physical footprint dimensions (2.00mm x 1.25mm). Height variation (0.60mm versus 0.65mm) is within acceptable PCB assembly tolerances for standard 0805 placement.

Q: What are the key differences between these parts?

A: The primary differences are tolerance specification (±1% versus ±0.1%), power rating (0.125W versus 0.25W), and temperature coefficient (±50ppm/°C versus ±25ppm/°C). The substitute part provides enhanced precision and thermal stability.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the RT0805FRE0712R7L and 3-1625868-7 are RoHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity ratings.

Q: Does the higher power rating of the substitute part affect circuit performance?

A: No. The 0.25W rating of the 3-1625868-7 is a performance enhancement that does not negatively impact circuits designed for the 0.125W RT0805FRE0712R7L. The substitute part can safely handle the same or greater thermal loads.

Q: Are there any height compatibility concerns for PCB assembly?

A: The height difference (0.024" versus 0.026") is minimal and within standard PCB assembly specifications for 0805 components. No design modifications are required.
