Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMC1/16-1104FTP is determined by strict equivalence across the following parameters:

Critical Parameters (Must Match Exactly):

• Resistance value: 1.1 MOhms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Package / Case: 0603 (1608 Metric)
• Composition: Thick Film
• Operating temperature range: -55°C ~ 155°C
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variations:

• Temperature coefficient: ±100ppm/°C to ±200ppm/°C (tighter specifications acceptable)
• Automotive qualification (AEC-Q200): Optional enhancement
• Physical dimensions: Minor variations within 0603 standard tolerance
• Manufacturer: Different manufacturers permitted if all critical parameters match

All three substitute parts meet these criteria and are therefore direct functional equivalents.

Parameter Comparison

Engineering Selection Recommendations

RMCF0603FT1M10 (Stackpole Electronics Inc): This substitute is recommended as the primary alternative. It maintains Active product status with the highest inventory availability (17,940 units). The component carries AEC-Q200 automotive qualification and ROHS3 compliance. The temperature coefficient of ±200ppm/°C is acceptable for applications where the original ±100ppm/°C specification is not critical. Physical dimensions are within 0603 standard tolerance (1.55mm vs. 1.60mm length).

KTR03EZPF1104 (Rohm Semiconductor): This substitute is suitable for applications requiring enhanced specifications. It maintains Active product status with AEC-Q200 automotive qualification, ROHS3 compliance, and matches the original temperature coefficient of ±100ppm/°C. The addition of high voltage capability provides extended application flexibility. Inventory availability is 8,289 units.

ERJ-3EKF1104V (Panasonic Electronic Components): This substitute is not recommended for new designs due to Obsolete product status. While it matches the original temperature coefficient (±100ppm/°C) and carries AEC-Q200 qualification with ROHS3 compliance, the obsolete classification indicates discontinued manufacturing. Current inventory of 10,299 units may support legacy system maintenance only.

Frequently Asked Questions (FAQ)

Q: Can RMCF0603FT1M10 replace RMC1/16-1104FTP in all applications?

A: Yes, RMCF0603FT1M10 is a direct functional equivalent. All critical electrical parameters match exactly: 1.1 MOhms resistance, ±1% tolerance, 0.1W power rating, and 0603 package. The temperature coefficient difference (±200ppm/°C vs. ±100ppm/°C) is acceptable unless the application specifically requires the tighter ±100ppm/°C specification.

Q: What is the difference between the three substitute parts?

A: All three substitutes meet the core electrical and mechanical requirements. RMCF0603FT1M10 and KTR03EZPF1104 are both Active products with automotive qualification. KTR03EZPF1104 offers the same temperature coefficient as the original (±100ppm/°C) and includes high voltage capability. ERJ-3EKF1104V is Obsolete and should not be selected for new designs.

Q: Are there any physical compatibility issues with these substitutes?

A: No. All substitutes use the 0603 (1608 Metric) package with identical height specifications (0.022" maximum seated height). Minor length variations (1.55mm to 1.60mm) fall within standard 0603 tolerance and do not affect PCB footprint compatibility.

Q: Which substitute should I choose for automotive applications?

A: Both RMCF0603FT1M10 and KTR03EZPF1104 carry AEC-Q200 automotive qualification. Select RMCF0603FT1M10 for general automotive use with higher inventory availability. Select KTR03EZPF1104 if the application requires the tighter ±100ppm/°C temperature coefficient or high voltage capability.

Q: Is RoHS compliance required?

A: The original RMC1/16-1104FTP does not specify RoHS status. All three substitutes are ROHS3 compliant, which provides regulatory alignment with current environmental standards. This is an enhancement over the original specification.

Q: Can I use ERJ-3EKF1104V for new product designs?

A: No. ERJ-3EKF1104V is classified as Obsolete, indicating discontinued manufacturing. Use only for legacy system maintenance or repair where existing designs already specify this part number.
