RMCS1206FT8K25 Equivalent & Substitute Parts

Part Overview

The RMCS1206FT8K25 is an 8.25 kOhms ±1% 0.25W thick film chip resistor in 1206 (3216 Metric) package manufactured by Stackpole Electronics Inc. This anti-sulfur resistor operates across -55°C to 155°C and is ROHS3 compliant with unlimited moisture sensitivity rating.

Finding equivalent and substitute parts is necessary when the primary part experiences supply constraints, inventory limitations, or when design requirements call for alternative certifications such as automotive AEC-Q200 qualification or enhanced moisture resistance features.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RMCS1206FT8K25 are qualified based on the following electrical and mechanical parameters:

• Resistance value: 8.25 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Termination count: 2
• Moisture sensitivity level: 1 (Unlimited)

Substitute parts may differ in the following attributes without affecting functional compatibility: manufacturer, series designation, specific dimensional tolerances (within package class), height seated maximum, features (anti-sulfur, moisture resistant, automotive AEC-Q200), and product status. Parts are grouped by their compliance certifications and feature sets.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status, ROHS3 Compliant):

RMCF1206FT8K25 (Stackpole Electronics Inc) is the manufacturer-recommended substitute from the same supplier. It maintains identical electrical specifications while adding automotive AEC-Q200 certification. This part is suitable for applications requiring automotive-grade reliability.

CRCW12068K25FKEA (Vishay Dale) provides automotive AEC-Q200 qualification with ROHS3 compliance and active product status. This part offers the highest inventory availability among automotive-qualified options.

RC1206FR-078K25L (YAGEO) is an active, ROHS3-compliant alternative with moisture-resistant features and the largest inventory stock. This part is suitable for general industrial applications.

CR1206-FX-8251ELF (Bourns Inc.) provides moisture-resistant construction with ROHS3 compliance and active status, offering an alternative to anti-sulfur construction.

Conditional Substitutes:

CRCW12068K25FKTA (Vishay Dale) is electrically and mechanically equivalent but is RoHS non-compliant and REACH-affected. This part is suitable only for applications where RoHS compliance is not required.

ERJ-8ENF8251V (Panasonic Electronic Components) carries "Not For New Designs" status despite ROHS3 compliance and automotive AEC-Q200 qualification. This part should be used only for legacy design maintenance or when no other options are available.

Frequently Asked Questions (FAQ)

Q: Can RMCF1206FT8K25 be used as a direct replacement for RMCS1206FT8K25?

A: Yes. Both parts share identical electrical specifications (8.25 kOhms ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C) and 1206 package. RMCF1206FT8K25 adds automotive AEC-Q200 certification and is the manufacturer-recommended substitute.

Q: What is the difference between anti-sulfur and moisture-resistant features?

A: Anti-sulfur construction (RMCS1206FT8K25) protects against sulfur-containing atmospheric corrosion. Moisture-resistant construction (CR1206-FX-8251ELF, RC1206FR-078K25L) provides protection against moisture ingress. Both are functionally equivalent for standard applications; feature selection depends on environmental exposure conditions.

Q: Are all substitute parts automotive-qualified?

A: No. RMCS1206FT8K25, CR1206-FX-8251ELF, and RC1206FR-078K25L do not carry AEC-Q200 certification. RMCF1206FT8K25, CRCW12068K25FKEA, CRCW12068K25FKTA, and ERJ-8ENF8251V are automotive AEC-Q200 qualified. Select automotive-qualified parts only when AEC-Q200 certification is a design requirement.

Q: Why is ERJ-8ENF8251V marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active development for this part. While functionally equivalent and currently in stock, it should not be selected for new designs. Use RMCF1206FT8K25, CRCW12068K25FKEA, or RC1206FR-078K25L for new designs.

Q: What is the significance of RoHS compliance status?

A: ROHS3-compliant parts (RMCS1206FT8K25, RMCF1206FT8K25, CR1206-FX-8251ELF, CRCW12068K25FKEA, ERJ-8ENF8251V, RC1206FR-078K25L) meet European Union restrictions on hazardous substances. CRCW12068K25FKTA is RoHS non-compliant and REACH-affected; use only in applications where RoHS compliance is not mandated.

Q: Are dimensional variations between substitute parts significant?

A: All substitute parts use the 1206 (3216 Metric) package class with standardized footprints. Dimensional variations (length 0.122" to 0.126", height 0.024" to 0.030") fall within package tolerance and do not affect PCB layout compatibility. Verify specific height requirements only if board clearance is constrained.

Q: Which substitute offers the best inventory availability?

A: RC1206FR-078K25L (YAGEO) has the highest inventory stock at 165,662 pieces. CRCW12068K25FKEA (Vishay Dale) offers 25,741 pieces with automotive AEC-Q200 certification. RMCF1206FT8K25 (Stackpole Electronics Inc) provides 16,379 pieces as the manufacturer-recommended option.
