Engineering Selection Recommendations

Direct Replacement (Equivalent Function): All listed substitute parts maintain electrical equivalence to the 1614947-1 across the specified operating range. Selection among active alternatives depends on application requirements:

RNCF0805BTE6K65 (Stackpole Electronics): Provides higher power dissipation capacity (0.25W) with automotive AEC-Q200 certification. Suitable for applications requiring enhanced thermal margin.
ERA-6AEB6651V (Panasonic): Active product with automotive AEC-Q200 rating and 0.125W power rating. Highest inventory availability (6852 pcs).
MCU08050D6651BP500 (Vishay Beyschlag): Anti-sulfur thin film construction with 0.125W rating. Operating temperature limited to -55°C to 125°C (does not extend to 155°C upper limit).
RG2012 Series (Susumu): Multiple variants offering progressive improvements in temperature coefficient (±25ppm/°C down to ±5ppm/°C) and tolerance (±0.1% down to ±0.02%). All include anti-sulfur coating and automotive AEC-Q200 certification. Full -55°C to 155°C operating range maintained across all variants.

Product Status Consideration: The 1614947-1 is obsolete. All substitute parts listed are active products with confirmed current availability, ensuring long-term supply chain continuity.

Compliance Status: All substitute parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes, matching the original part's regulatory status.

Frequently Asked Questions (FAQ)

Q: Can RNCF0805BTE6K65 replace 1614947-1 in all applications?

A: Yes. RNCF0805BTE6K65 maintains all critical electrical parameters (6.65 kΩ ±0.1%, -55°C to 155°C operating range) and identical 0805 package. The higher power rating (0.25W vs. 0.1W) provides additional thermal margin without affecting circuit performance.

Q: What is the difference between Susumu RG2012 variants (N, P, V series)?

A: The variants differ in temperature coefficient and tolerance specifications. RG2012N series has ±10ppm/°C, RG2012P series has ±25ppm/°C, and RG2012V series has ±5ppm/°C. All maintain 6.65 kΩ resistance and 0.125W power rating. Selection depends on circuit stability requirements across temperature extremes.

Q: Is MCU08050D6651BP500 suitable for applications requiring 155°C operation?

A: No. MCU08050D6651BP500 is rated only to 125°C maximum operating temperature, which does not meet the original part's -55°C to 155°C specification. Use alternative Susumu RG2012 or Panasonic ERA-6AEB6651V variants for full temperature range compatibility.

Q: Do all substitute parts have automotive AEC-Q200 certification?

A: No. Only RNCF0805BTE6K65, ERA-6AEB6651V, and all Susumu RG2012 variants carry AEC-Q200 certification. MCU08050D6651BP500 does not list AEC-Q200 rating. Select AEC-Q200 certified parts for automotive applications.

Q: Can I use a substitute part with tighter tolerance (±0.05% or ±0.02%) in place of ±0.1%?

A: Yes. Tighter tolerance specifications are backward compatible. Parts with ±0.05% or ±0.02% tolerance exceed the ±0.1% requirement and provide improved accuracy without circuit modification.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes. All listed substitute parts are supplied in Tape & Reel (TR) packaging, matching the original part's standard production format for automated assembly.

Q: What is the significance of anti-sulfur coating in Susumu and Vishay parts?

A: Anti-sulfur coating protects the resistor element from sulfur-containing environmental contaminants, extending component reliability in harsh industrial and automotive environments. This feature does not affect electrical performance or circuit compatibility.
