Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMCS0805FT2K61 is determined by the following critical parameters:

• Resistance Value: 2.61 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Package / Case: 0805 (2012 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match or wider range acceptable)
• Power Rating: 0.125W minimum (equal or higher acceptable)
• Terminations: 2 (exact match required)
• RoHS / REACH Compliance: ROHS3 Compliant, REACH Unaffected (maintained across substitutes)

All substitute parts listed maintain these core electrical and mechanical specifications. Variations in features (such as automotive AEC-Q200 qualification, moisture resistance, or pulse withstanding capability) represent enhancements that do not compromise compatibility with the original part specification.

Parameter Comparison

Engineering Selection Recommendations

RMCF0805FT2K61 (Stackpole Electronics Inc): Direct manufacturer equivalent with automotive AEC-Q200 qualification. Recommended for applications requiring automotive-grade reliability. Significantly higher inventory availability (46,212 units) supports supply chain continuity.

AC0805FR-072K61L (YAGEO): Combines automotive AEC-Q200 qualification with moisture-resistant construction. Suitable for applications in humid or corrosive environments. Moderate inventory levels (11,075 units).

CRCW08052K61FKEA (Vishay Dale): Automotive AEC-Q200 qualified with the lowest seated height (0.020" / 0.50mm), beneficial for space-constrained PCB layouts. High inventory availability (41,844 units).

ERJ-6ENF2611V (Panasonic Electronic Components): Automotive AEC-Q200 qualified with highest inventory availability (85,548 units). Suitable for high-volume production requirements. Seated height of 0.028" (0.70mm) requires clearance verification.

ERJ-P06F2611V (Panasonic Electronic Components): Enhanced power rating of 0.5W (1/2W) with pulse withstanding capability. Applicable only when higher power dissipation or transient pulse immunity is required. Lower inventory (5,282 units).

RC0805FR-072K61L (YAGEO): Moisture-resistant construction without automotive qualification. Highest inventory availability (181,281 units). Suitable for consumer and industrial applications in moisture-prone environments.

All substitute parts maintain ROHS3 compliance and REACH unaffected status. Selection should prioritize application requirements (automotive qualification, moisture resistance, pulse withstanding), PCB layout constraints (seated height), and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can RMCF0805FT2K61 replace RMCS0805FT2K61 in all applications?

A: Yes. RMCF0805FT2K61 is a direct equivalent from the same manufacturer with identical electrical specifications (2.61 kOhms, ±1%, 0.125W, 0805 package). The addition of automotive AEC-Q200 qualification represents an enhancement that does not compromise compatibility. Seated height differs by 0.002" (0.05mm), which is negligible for most PCB designs.

Q: Is ERJ-P06F2611V compatible with the original RMCS0805FT2K61?

A: ERJ-P06F2611V is electrically compatible but has a higher power rating (0.5W vs. 0.125W). This substitution is valid only when the application requires or can tolerate higher power dissipation. The 0805 package and all other electrical parameters remain identical. Verify PCB layout clearance due to increased seated height (0.028" / 0.70mm).

Q: What is the difference between automotive AEC-Q200 qualified and non-qualified versions?

A: Automotive AEC-Q200 qualification indicates the part meets automotive industry reliability and quality standards. Parts such as RMCF0805FT2K61, AC0805FR-072K61L, CRCW08052K61FKEA, and ERJ-6ENF2611V carry this certification. Non-qualified versions (RMCS0805FT2K61, RC0805FR-072K61L) are suitable for consumer and industrial applications. Selection depends on end-use application requirements.

Q: Does moisture resistance affect electrical performance?

A: No. Moisture-resistant construction (featured in AC0805FR-072K61L and RC0805FR-072K61L) enhances environmental durability without altering electrical specifications. These parts maintain identical resistance, tolerance, temperature coefficient, and operating temperature range. Moisture resistance is beneficial in humid, coastal, or high-humidity manufacturing environments.

Q: Are there PCB layout considerations when substituting these parts?

A: Yes. Seated height varies across substitutes: CRCW08052K61FKEA (0.020" / 0.50mm) is lowest, while ERJ-6ENF2611V and ERJ-P06F2611V (0.028" / 0.70mm) are highest. Verify clearance with adjacent components, solder mask openings, and conformal coating requirements. All parts use identical 0805 (2012 Metric) footprint dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm).

Q: Which substitute offers the best supply chain availability?

A: RC0805FR-072K61L (YAGEO) has the highest inventory at 181,281 units, followed by ERJ-6ENF2611V (Panasonic) at 85,548 units. For automotive-qualified alternatives, CRCW08052K61FKEA (Vishay Dale) offers 41,844 units and RMCF0805FT2K61 (Stackpole) offers 46,212 units. Selection should balance availability with application-specific requirements.
