Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RMC1/8-3014FTP are qualified based on the following criteria:

Electrical Compatibility: All substitute parts maintain the core electrical specifications: 3.01 MOhms resistance value, ±1% tolerance, and 0.25W power rating. These parameters are non-negotiable for direct substitution.

Package Compatibility: All qualified substitutes use the 1206 (3216 Metric) surface mount package with 2 terminations, ensuring mechanical and footprint compatibility on printed circuit boards.

Environmental Specifications: All parts operate across the -55°C ~ 155°C temperature range and carry MSL 1 rating, confirming suitability for standard manufacturing and storage conditions.

Composition: All substitute parts use thick film construction, maintaining consistent performance characteristics and manufacturing processes.

Substitution Categories:

• Direct Substitutes (Equivalent Performance): RMCF1206FT3M01 (Stackpole Electronics Inc) provides equivalent electrical and mechanical specifications with automotive AEC-Q200 qualification.

• Upgrade Substitutes (Enhanced Performance): KTR18EZPF3014 (Rohm Semiconductor) and RC1206FR-073M01L (YAGEO) offer improved temperature coefficient (±100ppm/°C versus ±200ppm/°C) and additional certifications while maintaining all core compatibility parameters.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Equivalent Functionality):

RMCF1206FT3M01 from Stackpole Electronics Inc is the primary direct substitute. This part maintains identical electrical specifications and mechanical compatibility while adding AEC-Q200 automotive qualification and ROHS3 compliance. Selection of this part is appropriate when the original RMC1/8-3014FTP is unavailable and equivalent performance is required.

For Enhanced Performance Applications:

KTR18EZPF3014 from Rohm Semiconductor is classified as an upgrade substitute. This part provides superior temperature coefficient performance (±100ppm/°C versus ±200ppm/°C), AEC-Q200 automotive qualification, and ROHS3 compliance. The improved temperature stability makes this part suitable for applications requiring tighter resistance tolerance over extended temperature ranges. High voltage capability is an additional feature not present in the base part.

RC1206FR-073M01L from YAGEO is also classified as an upgrade substitute with improved temperature coefficient (±100ppm/°C) and moisture-resistant construction. ROHS3 compliance is included. This part is suitable for applications requiring enhanced environmental protection and temperature stability.

Product Status Consideration:

All parts maintain Active product status, confirming ongoing availability and manufacturer support. No obsolescence risk is associated with any substitute option.

Frequently Asked Questions (FAQ)

Q: Can RMCF1206FT3M01 be used as a direct replacement for RMC1/8-3014FTP?

A: Yes. RMCF1206FT3M01 maintains identical resistance value (3.01 MOhms), tolerance (±1%), power rating (0.25W), package (1206), composition (thick film), and operating temperature range (-55°C ~ 155°C). The part is mechanically and electrically compatible for direct substitution.

Q: What is the difference between the base part and the upgrade substitutes?

A: The primary difference is temperature coefficient. The RMC1/8-3014FTP and RMCF1206FT3M01 have ±200ppm/°C temperature coefficient, while KTR18EZPF3014 and RC1206FR-073M01L offer improved ±100ppm/°C performance. This means the upgrade parts maintain tighter resistance tolerance across the full operating temperature range. Additionally, upgrade parts include ROHS3 compliance and automotive certifications.

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

A: Yes. All substitute parts are supplied in Tape & Reel (TR) format, matching the original RMC1/8-3014FTP packaging. This ensures compatibility with standard pick-and-place assembly equipment.

Q: Do the substitute parts have the same physical dimensions?

A: All parts use the 1206 (3216 Metric) package with 2 terminations. Minor dimensional variations exist: RMC1/8-3014FTP and RC1206FR-073M01L measure 0.122" L x 0.063" W, while RMCF1206FT3M01 and KTR18EZPF3014 measure 0.126" L x 0.063" W. Height differences are also minimal (0.025" to 0.028" maximum seated height). These variations are within standard PCB footprint tolerances and do not affect interchangeability.

Q: Which substitute part should be selected for automotive applications?

A: Both RMCF1206FT3M01 and KTR18EZPF3014 carry AEC-Q200 automotive qualification. KTR18EZPF3014 additionally features high voltage capability and superior temperature coefficient (±100ppm/°C). Selection depends on specific automotive application requirements.

Q: Are all parts ROHS3 compliant?

A: RMCF1206FT3M01, KTR18EZPF3014, and RC1206FR-073M01L are ROHS3 compliant. The original RMC1/8-3014FTP does not specify ROHS status in the provided data.

Q: What is the moisture sensitivity level for all parts?

A: All parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage, handling, or manufacturing processes.
