RMC1/8K3000FTP Equivalent & Substitute Parts

Part Overview

The RMC1/8K3000FTP is a 300 Ohms ±1% 0.25W (1/4W) chip resistor manufactured by Kamaya Inc. in 1206 (3216 Metric) package format with thick film composition. This component is classified as Active product status and is currently in stock with 713 pieces available.

Substitute parts are necessary when the primary part becomes unavailable, when alternative manufacturers offer improved lead times, or when design requirements specify compliance certifications such as AEC-Q200 automotive qualification or enhanced moisture resistance features.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMC1/8K3000FTP is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Resistance value: 300 Ohms
• 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
• Moisture sensitivity level: 1 (Unlimited)
• Number of terminations: 2

All substitute parts listed meet these core electrical and mechanical specifications. Variations in physical dimensions (length, width, height) within acceptable tolerances, packaging format (Tape & Reel vs. Cut Tape), and additional certifications (AEC-Q200, moisture resistance) do not disqualify substitution but may influence selection based on application requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status, Highest Availability):

CRG1206F300R (TE Connectivity) and RMCF1206FT300R (Stackpole Electronics) are recommended as primary substitutes. Both maintain Active product status, offer high inventory levels (846 and 145,491 pieces respectively), and comply with ROHS3 standards. RMCF1206FT300R includes AEC-Q200 automotive qualification, suitable for applications requiring automotive-grade reliability.

Secondary Substitutes (Active Status, Specialized Features):

KTR18EZPF3000 (Rohm Semiconductor) is Active with 2,354 pieces in stock and provides both AEC-Q200 automotive qualification and high voltage capability. RC1206FR-07300RL (YAGEO) is Active with the highest inventory (70,300 pieces) and includes moisture-resistant features, available in Cut Tape & Digi-Reel packaging format.

Not Recommended for New Designs:

ERJ-8ENF3000V (Panasonic) carries "Not For New Designs" status despite high inventory (45,846 pieces) and AEC-Q200 qualification. This designation indicates the manufacturer has discontinued active development for this part number.

All substitute parts comply with REACH regulations and carry EAR99 ECCN classification matching the primary part.

Frequently Asked Questions (FAQ)

Q: Can I substitute RMC1/8K3000FTP with any of the listed parts in my existing design?

A: Yes. All listed substitute parts meet the core electrical specifications (300 Ohms ±1%, 0.25W, 1206 package, thick film, ±100ppm/°C, -55°C to 155°C operating range). Physical dimensions vary slightly within acceptable tolerances. Verify PCB layout accommodates maximum height specifications if space is constrained.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging?

A: Tape & Reel packaging is supplied on continuous carrier tape suitable for automated pick-and-place assembly. Cut Tape & Digi-Reel is supplied in shorter tape segments on reels, typically for lower-volume applications or manual assembly. Both formats contain identical components; packaging selection depends on assembly process requirements.

Q: Why is ERJ-8ENF3000V marked "Not For New Designs"?

A: This designation indicates Panasonic has transitioned this part number to end-of-life status and recommends alternative parts for new product development. While existing inventory is available, using this part in new designs may result in future supply constraints.

Q: Do the substitute parts require different PCB footprints?

A: No. All parts use the 1206 (3216 Metric) package with identical footprint specifications. Minor variations in component body dimensions (length 3.10mm to 3.20mm, width 1.55mm to 1.60mm, height 0.65mm to 0.70mm) are within standard PCB design tolerances and do not require footprint modification.

Q: Which substitute offers the best availability?

A: RC1206FR-07300RL (YAGEO) has the highest inventory at 70,300 pieces. RMCF1206FT300R (Stackpole) follows with 145,491 pieces. Both are suitable for high-volume production requirements.

Q: Are all substitutes RoHS compliant?

A: CRG1206F300R, KTR18EZPF3000, RC1206FR-07300RL, and RMCF1206FT300R are ROHS3 compliant. ERJ-8ENF3000V is also ROHS3 compliant. The primary part RMC1/8K3000FTP does not specify RoHS status in available documentation.

Q: Which substitute is best for automotive applications?

A: KTR18EZPF3000 and RMCF1206FT300R both carry AEC-Q200 automotive qualification. RMCF1206FT300R offers higher inventory (145,491 vs. 2,354 pieces) and Active product status, making it the preferred choice for automotive designs requiring qualified components.
