Tolerance: ±5% (matching tolerance class)
Power rating: 0.125W / 1/8W (exact match required)
Package: 0805 (2012 Metric) (exact match required)
Composition: Thick Film (exact match required)
Operating temperature range: -55°C to 155°C (minimum requirement)
Moisture Sensitivity Level: MSL 1 or better

Secondary Substitution Criteria (Upgrades):

Engineering Selection Recommendations

Direct Equivalent Selection (±5% Tolerance, ±200ppm/°C):

For applications requiring exact specification matching without tolerance or temperature coefficient upgrades, the following active parts are recommended:

ERJ-6GEYJ684V (Panasonic): Highest inventory availability (44,830 units), AEC-Q200 certified, active production status. Suitable for automotive and general industrial applications.
RMCF0805JT680K (Stackpole Electronics): 12,821 units in stock, AEC-Q200 certified, active production status. Recommended for automotive-grade designs.
RC0805JR-07680KL (YAGEO): 42,393 units available, moisture-resistant thick film composition, active production status. Suitable for high-humidity environments.

The MCR10ERTJ684 (Rohm Semiconductor) is discontinued at DiGi Electronics and should not be selected for new designs despite available inventory.

Upgrade Selection (±1% Tolerance, ±100ppm/°C):

For applications requiring improved tolerance accuracy and temperature stability, upgrade parts provide enhanced performance:

RMCF0805FT680K (Stackpole Electronics): 45,353 units in stock, AEC-Q200 certified, active production. Recommended primary upgrade for automotive applications requiring tighter tolerance.
ERJ-6ENF6803V (Panasonic): 224,306 units available, highest inventory level, AEC-Q200 certified, active production. Recommended for high-volume applications with automotive requirements.
KTR10EZPF6803 (Rohm Semiconductor): 5,731 units in stock, AEC-Q200 certified, high-voltage rated, active production. Recommended for high-voltage circuit applications.
RC0805FR-07680KL (YAGEO): 64,225 units available, moisture-resistant composition, active production. Recommended for moisture-sensitive environments.

The CRG0805F680K (TE Connectivity) and MCR10ERTF6803 (Rohm Semiconductor) have limited inventory (700 and 980 units respectively) and should be considered only when other options are unavailable.

Frequently Asked Questions (FAQ)

Q: Can I substitute the RMC1/10-684JTP with a ±1% tolerance part?

A: Yes. Parts with ±1% tolerance are backward compatible with designs specified for ±5% tolerance. The tighter tolerance provides improved accuracy without reducing functionality. Examples include RMCF0805FT680K, ERJ-6ENF6803V, and RC0805FR-07680KL.

Q: What is the difference between direct equivalents and upgrade parts?

A: Direct equivalents match all electrical specifications of the RMC1/10-684JTP (680 kΩ, ±5%, ±200ppm/°C). Upgrade parts maintain the same resistance and power rating but offer tighter tolerance (±1%) and improved temperature coefficient (±100ppm/°C), resulting in better circuit performance and stability.

Q: Are all substitute parts available in the same packaging?

A: Yes. All listed substitute parts are supplied in 0805 (2012 Metric) package format. However, packaging type differs: some are supplied in Tape & Reel (TR), while others are Cut Tape (CT) & Digi-Reel®. Verify packaging compatibility with your assembly equipment before selection.

Q: Which substitute parts have AEC-Q200 automotive certification?

A: The following parts carry AEC-Q200 certification: ERJ-6GEYJ684V, RMCF0805JT680K, ERJ-6ENF6803V, KTR10EZPF6803, and RMCF0805FT680K. Select these for automotive applications or designs requiring automotive-grade reliability standards.

Q: What is the inventory status of each substitute part?

A: ERJ-6ENF6803V has the highest availability (224,306 units), followed by RC0805FR-07680KL (64,225 units) and RMCF0805FT680K (45,353 units). MCR10ERTJ684 and MCR10ERTF6803 are discontinued at DiGi Electronics despite available inventory and should not be selected for new designs.

Q: Can I use parts with different temperature coefficients interchangeably?

A: Parts with ±100ppm/°C temperature coefficient are suitable replacements for designs specified with ±200ppm/°C. The lower temperature coefficient provides improved stability across the operating temperature range (-55°C to 155°C) and is backward compatible.

Q: Which substitute offers the best moisture resistance?

A: RC0805FR-07680KL and RC0805JR-07680KL (both YAGEO) feature moisture-resistant thick film composition. Both maintain MSL 1 rating and are suitable for high-humidity or moisture-sensitive applications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant. The original RMC1/10-684JTP does not specify RoHS status in the provided data.
