Key Parameters

Substitute Part Grouping Explanation

Substitute parts are organized into three functional categories based on allowed electrical and mechanical parameters:

Upgrade Substitutes (Enhanced Tolerance): RT1206BRD076K49L, ERA-8AEB6491V, and RG3216P-6491-B-T5 maintain the same 6.49 kOhms resistance and 0.25W power rating but offer improved tolerance of ±0.1% compared to the original ±1%. These parts are electrically compatible and physically interchangeable within the 1206 package footprint. Temperature coefficient is reduced to ±25ppm/°C, providing superior stability.

Automotive-Qualified Substitutes: ERA-8AEB6491V and RG3216P-6491-B-T5 carry AEC-Q200 automotive qualification, suitable for applications requiring automotive-grade reliability. RG3216P-6491-B-T5 additionally features anti-sulfur coating for enhanced environmental resistance.

Higher Power Rating Substitute: RNCP1206FTD6K49 provides the same 6.49 kOhms resistance and 1206 package but with doubled power rating (0.5W vs. 0.25W) and ±1% tolerance matching the original specification. This part accommodates applications requiring increased power dissipation capacity.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Same Specifications): RT1206FRE076K49L can be directly replaced with RT1206BRD076K49L when improved tolerance and temperature stability are acceptable. Both parts are YAGEO products with identical package dimensions and active production status.

Automotive Applications: For designs requiring automotive-grade components, ERA-8AEB6491V or RG3216P-6491-B-T5 are appropriate selections. Both carry AEC-Q200 qualification and maintain electrical compatibility. RG3216P-6491-B-T5 provides additional anti-sulfur protection for harsh environments.

Increased Power Dissipation: RNCP1206FTD6K49 is selected when circuit design requires 0.5W power handling while maintaining 6.49 kOhms resistance. This part maintains ±1% tolerance and operates across the same temperature range.

Compliance Considerations: All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and REACH unaffected status, ensuring regulatory compatibility with the original specification.

Frequently Asked Questions (FAQ)

Q: Can RT1206BRD076K49L be used as a direct drop-in replacement for RT1206FRE076K49L?

A: Yes. Both parts share identical 1206 package dimensions, 6.49 kOhms resistance, and 0.25W power rating. The primary difference is improved tolerance (±0.1% vs. ±1%) and lower temperature coefficient (±25ppm/°C vs. ±50ppm/°C), making RT1206BRD076K49L suitable for precision applications.

Q: What is the difference between the upgrade substitutes and RNCP1206FTD6K49?

A: Upgrade substitutes (RT1206BRD076K49L, ERA-8AEB6491V, RG3216P-6491-B-T5) maintain the original 0.25W power rating with improved tolerance. RNCP1206FTD6K49 doubles the power rating to 0.5W while maintaining ±1% tolerance, addressing applications requiring higher power dissipation.

Q: Are ERA-8AEB6491V and RG3216P-6491-B-T5 interchangeable?

A: Both parts are electrically and mechanically compatible within the 1206 package. ERA-8AEB6491V is Panasonic AEC-Q200 qualified. RG3216P-6491-B-T5 is Susumu AEC-Q200 qualified with additional anti-sulfur coating. Selection depends on supplier availability and specific environmental requirements.

Q: Can RNCP1206FTD6K49 be used in place of RT1206FRE076K49L?

A: Yes, with design consideration. RNCP1206FTD6K49 provides the same 6.49 kOhms resistance and 1206 package but offers doubled power capacity (0.5W vs. 0.25W). The higher temperature coefficient (±100ppm/°C vs. ±50ppm/°C) may affect precision circuits. Use only when increased power handling is required.

Q: What does AEC-Q200 qualification mean?

A: AEC-Q200 is an automotive industry standard for passive component reliability. ERA-8AEB6491V and RG3216P-6491-B-T5 meet this qualification, making them suitable for automotive and high-reliability applications requiring enhanced quality assurance.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and REACH unaffected status, ensuring regulatory compatibility with the original RT1206FRE076K49L specification.
