Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RT0805FRE0728K7L are qualified based on the following criteria:

Mandatory Matching Parameters:

• Resistance value: 28.7 kOhms
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Operating temperature range: -55°C to 155°C minimum
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

Allowable Variations:

• Tolerance: ±1% or tighter (±0.1% acceptable)
• Power rating: Equal to or greater than 0.125W
• Temperature coefficient: ±50ppm/°C or better
• Height - Seated (Max): Within 0.026" (0.65mm)

Substitute parts meeting these criteria are functionally interchangeable in applications where the RT0805FRE0728K7L is specified.

Parameter Comparison

Engineering Selection Recommendations

4-2176093-6 (TE Connectivity Passive Product): This part offers improved tolerance (±0.1%) and higher power rating (0.25W) compared to the main part. It maintains identical operating temperature range and RoHS3 compliance. The increased height (0.026" vs 0.024") remains within acceptable PCB assembly tolerances for 0805 packages. Suitable for applications requiring enhanced power dissipation capability or tighter tolerance specifications.

ERA-6AEB2872V (Panasonic Electronic Components): This part provides tighter tolerance (±0.1%), improved temperature coefficient (±25ppm/°C), and AEC-Q200 automotive qualification. Physical dimensions and power rating match the main part exactly. Recommended for automotive applications or systems requiring automotive-grade component reliability.

RG2012P-2872-B-T5 (Susumu): This part combines tighter tolerance (±0.1%), improved temperature coefficient (±25ppm/°C), AEC-Q200 automotive qualification, and anti-sulfur coating. The lowest seated height (0.020") provides additional PCB assembly margin. Recommended for automotive applications in corrosive environments or where anti-sulfur protection is specified.

All substitute parts maintain Active product status and full RoHS3 compliance with MSL 1 rating.

Frequently Asked Questions (FAQ)

Q: Can 4-2176093-6 replace RT0805FRE0728K7L in all applications? A: Yes, within the constraint that the increased height (0.026" vs 0.024") must not conflict with PCB assembly clearances. The higher power rating (0.25W vs 0.125W) and tighter tolerance (±0.1% vs ±1%) are compatible with all applications requiring the original part.

Q: What is the advantage of ERA-6AEB2872V over the main part? A: ERA-6AEB2872V offers AEC-Q200 automotive qualification, tighter tolerance (±0.1%), and improved temperature coefficient (±25ppm/°C). These characteristics are beneficial for automotive and high-reliability applications where component stability and qualification are critical.

Q: Why does RG2012P-2872-B-T5 have anti-sulfur coating? A: Anti-sulfur coating protects the resistor from sulfur-containing environmental contaminants that can degrade thin film resistor performance. This feature is specified for applications in industrial or corrosive environments.

Q: Are all substitute parts in the same 0805 package? A: Yes, all parts use the 0805 (2012 Metric) package form factor. Physical dimensions (0.079" L x 0.049" W) are identical. Seated heights vary slightly (0.020" to 0.026") but remain within standard PCB assembly tolerances for this package class.

Q: Do substitute parts maintain the same moisture sensitivity rating? A: Yes, all parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.

Q: Can I use ERA-6AEB2872V or RG2012P-2872-B-T5 in non-automotive applications? A: Yes, automotive-qualified parts (AEC-Q200) are fully compatible with non-automotive applications. The automotive qualification represents an additional quality and reliability standard, not a limitation.
