RMC1/8K5100FTP Equivalent & Substitute Parts

Part Overview

The RMC1/8K5100FTP is a 510 Ohm ±1% 0.25W (1/4W) chip resistor manufactured by Kamaya Inc. in the 1206 (3216 Metric) package. This thick film resistor operates across -55°C to 155°C and is classified as Active product status with unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and packaging formats are required for design flexibility, inventory management, or supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMC1/8K5100FTP is determined by strict equivalence across the following parameters:

Mandatory Matching Criteria:

• Resistance value: 510 Ohms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Composition: Thick Film
• Package: 1206 (3216 Metric)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Moisture sensitivity level: 1 (Unlimited)
• Number of terminations: 2

All identified substitute parts meet these mandatory criteria. Variations in physical dimensions (length, width, height) within standard manufacturing tolerances, packaging format (Tape & Reel vs. Cut Tape), and optional features (Automotive AEC-Q200 certification, moisture resistance) do not disqualify substitution but may influence selection based on application requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

RMCF1206FT510R (Stackpole Electronics Inc) is the preferred substitute. It maintains Active product status, carries Automotive AEC-Q200 certification, and has the highest inventory availability (67,300 pcs). This part is suitable for both commercial and automotive applications.

CRG1206F510R (TE Connectivity Passive Product) is an alternative with Active status and ROHS3 compliance. Inventory is moderate (707 pcs).

RC1206FR-07510RL (YAGEO) offers Active status with moisture-resistant features and substantial inventory (20,200 pcs). This part is suitable for applications requiring enhanced moisture protection.

KTR18EZPF5100 (Rohm Semiconductor) provides Active status with Automotive AEC-Q200 and High Voltage features. Inventory is adequate (2,927 pcs).

RC3216F511CS (Samsung Electro-Mechanics) maintains Active status with moisture-resistant composition. Packaging format differs (Cut Tape & Digi-Reel® instead of Tape & Reel). Inventory is limited (749 pcs).

Secondary Substitute (Not For New Designs):

ERJ-8ENF5100V (Panasonic Electronic Components) carries "Not For New Designs" status despite high inventory (50,529 pcs) and Automotive AEC-Q200 certification. This part is suitable only for legacy design support or replacement applications.

Frequently Asked Questions (FAQ)

Q: Can all listed substitute parts replace the RMC1/8K5100FTP in existing designs?

A: All substitute parts meet the mandatory electrical and mechanical specifications (510 Ω ±1%, 0.25W, 1206 package, ±100ppm/°C, -55°C to 155°C operating range, MSL 1). However, ERJ-8ENF5100V carries "Not For New Designs" status and should be used only for legacy applications or direct replacements in existing production.

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

A: Tape & Reel (TR) packaging is supplied on continuous carrier tape suitable for automated pick-and-place assembly. Cut Tape (CT) & Digi-Reel® packaging, as used by RC3216F511CS, provides smaller quantities on cut tape segments. Both formats contain identical components; packaging selection depends on production volume and assembly equipment compatibility.

Q: Do automotive-rated parts (AEC-Q200) provide advantages over standard parts?

A: Automotive AEC-Q200 certification (present in RMCF1206FT510R, ERJ-8ENF5100V, and KTR18EZPF5100) indicates compliance with automotive reliability and quality standards. These parts are suitable for automotive applications but are electrically and mechanically equivalent to non-automotive rated alternatives for general-purpose use.

Q: Are there differences in physical dimensions between substitute parts?

A: Minor dimensional variations exist within standard manufacturing tolerances. Length ranges from 0.122" to 0.126" (3.10mm to 3.20mm), width from 0.061" to 0.063" (1.55mm to 1.60mm), and height from 0.025" to 0.028" (0.65mm to 0.70mm). These variations do not affect electrical performance or PCB footprint compatibility for standard 1206 designs.

Q: What does "Moisture Resistant" feature indicate?

A: Moisture-resistant composition (featured in RC1206FR-07510RL and RC3216F511CS) provides enhanced protection against humidity and moisture ingress. All listed parts maintain MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: Which substitute offers the best inventory availability?

A: RMCF1206FT510R (Stackpole Electronics Inc) provides the highest inventory with 67,300 pcs in stock, followed by ERJ-8ENF5100V (Panasonic) with 50,529 pcs. For new designs, RMCF1206FT510R is recommended due to its Active status combined with high availability.
