Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Primary Matching Parameters:

• Resistance value: 649 Ohms (exact match required)
• Package form factor: 0805 (2012 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Allowable Variations:

• Tolerance: May be equal to or tighter than ±1% (±0.1% or ±0.5% acceptable)
• Power rating: May be equal to or greater than 0.125W (0.25W acceptable)
• Temperature coefficient: May be equal to or lower than ±50ppm/°C (±25ppm/°C acceptable)
• Certifications: Additional automotive (AEC-Q200) or anti-sulfur features permitted

All identified substitute parts meet these criteria and are suitable for direct replacement in applications where the RT0805FRE07649RL is specified.

Parameter Comparison

Engineering Selection Recommendations

Standard Industrial Applications: RT0805BRD07649RL (YAGEO) provides tighter tolerance (±0.1%) and improved temperature coefficient (±25ppm/°C) while maintaining identical power rating and package specifications. This part is suitable for applications requiring enhanced precision without additional environmental certifications.

Higher Power Dissipation Requirements: 2176092-1 (TE Connectivity Passive Product) offers doubled power rating (0.25W) in the same 0805 package footprint, accommodating applications with elevated thermal demands while maintaining ±0.1% tolerance and ±25ppm/°C temperature coefficient.

Automotive and Harsh Environment Applications: ERA-6AEB6490V (Panasonic Electronic Components) and RG2012P-6490-B-T5 (Susumu) both carry AEC-Q200 automotive qualification. RG2012P-6490-B-T5 additionally features anti-sulfur protection for corrosive environments. Both maintain ±0.1% tolerance and ±25ppm/°C temperature coefficient.

Cost-Optimized Automotive Alternative: ERA-6AED6490V (Panasonic Electronic Components) provides AEC-Q200 qualification with relaxed tolerance (±0.5%) at reduced cost, suitable for automotive applications where ±1% tolerance margin is acceptable.

All substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's environmental compliance profile.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD07649RL directly replace RT0805FRE07649RL? A: Yes. Both parts share identical resistance (649 Ohms), power rating (0.125W), and 0805 package specifications. RT0805BRD07649RL offers improved tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C), making it a direct upgrade.

Q: Is 2176092-1 suitable for applications designed for 0.125W power dissipation? A: Yes. The 2176092-1 is rated for 0.25W (1/4W), which exceeds the 0.125W requirement. Higher power rating does not create compatibility issues in circuits designed for lower power dissipation. Physical dimensions remain identical (0805 package).

Q: What is the difference between ERA-6AEB6490V and ERA-6AED6490V? A: Both are Panasonic automotive-qualified (AEC-Q200) 0805 resistors with 649 Ohm resistance. ERA-6AEB6490V has ±0.1% tolerance, while ERA-6AED6490V has ±0.5% tolerance. Both share identical temperature coefficient (±25ppm/°C) and power rating (0.125W).

Q: Why does RG2012P-6490-B-T5 specify anti-sulfur protection? A: Anti-sulfur protection is a material enhancement that prevents sulfur-induced corrosion in high-sulfur environments. This feature is beneficial in automotive and industrial applications but does not affect electrical performance or compatibility in standard applications.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the original RT0805FRE07649RL specification.

Q: Can these parts be used interchangeably on the same PCB assembly? A: Yes. All substitute parts use identical 0805 (2012 Metric) package form factor with matching footprint dimensions (0.079" L x 0.049" W). PCB layout and reflow profiles require no modification.
