Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC3216F5R1CS are qualified based on the following mandatory matching parameters:

Electrical Specifications:

• Resistance value: 5.1 Ohms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)

Mechanical Specifications:

• Package type: 1206 (3216 Metric)
• Number of terminations: 2
• Physical dimensions compatible with 1206 footprint

Environmental & Compliance:

• Operating temperature range: -55°C ~ 155°C
• Moisture sensitivity level: MSL 1 (Unlimited)
• RoHS3 compliance
• REACH unaffected status

All three substitute parts meet these core criteria. Additional features such as automotive AEC-Q200 qualification or enhanced temperature coefficient performance represent value-added characteristics that do not disqualify substitution but indicate enhanced reliability for specific applications.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are qualified for direct replacement of the RC3216F5R1CS based on matching electrical and mechanical specifications. Selection among substitutes depends on application-specific requirements:

RMCF1206FT5R10 (Stackpole Electronics Inc): This part carries AEC-Q200 automotive qualification and demonstrates improved temperature coefficient performance (±200ppm/°C versus ±300ppm/°C of the original). Suitable for automotive and high-reliability applications requiring enhanced stability. Available in Tape & Reel packaging with 37,055 pieces in stock.

RC1206FR-075R1L (YAGEO): This part maintains moisture-resistant characteristics matching the original RC3216F5R1CS and offers improved temperature coefficient (±200ppm/°C). Dimensions are 0.122" L x 0.063" W, representing a minor variation within 1206 package tolerance. Available in Cut Tape & Digi-Reel packaging with highest inventory availability (28,050 pieces).

KTR18EZPF5R10 (Rohm Semiconductor): This part provides the lowest temperature coefficient (±100ppm/°C) and carries AEC-Q200 automotive qualification with high-voltage designation. Suitable for precision applications and automotive environments requiring superior temperature stability. Available in Tape & Reel packaging with 5,961 pieces in stock.

All parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 rating, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can RMCF1206FT5R10, RC1206FR-075R1L, and KTR18EZPF5R10 be used interchangeably with RC3216F5R1CS?

A: Yes. All three parts meet the core electrical specifications (5.1 Ohms ±1%, 0.25W), mechanical package requirements (1206 / 3216 Metric), and environmental ratings (-55°C ~ 155°C, MSL 1, ROHS3 compliant). They are functionally equivalent for direct circuit replacement.

Q: What is the significance of temperature coefficient differences?

A: Temperature coefficient indicates resistance value drift across the operating temperature range. The RC3216F5R1CS has ±300ppm/°C, while substitutes range from ±100ppm/°C to ±200ppm/°C. Lower values indicate greater stability. For precision applications, KTR18EZPF5R10 (±100ppm/°C) or RMCF1206FT5R10 and RC1206FR-075R1L (both ±200ppm/°C) provide improved performance.

Q: Are there packaging differences that affect PCB assembly?

A: RC1206FR-075R1L has slightly smaller length dimensions (0.122" versus 0.126") but remains within 1206 package specifications. RMCF1206FT5R10 has maximum seated height of 0.028" versus 0.026" for other parts. These variations are within standard 1206 tolerance and do not affect PCB footprint compatibility.

Q: Which substitute is recommended for automotive applications?

A: Both RMCF1206FT5R10 and KTR18EZPF5R10 carry AEC-Q200 automotive qualification. KTR18EZPF5R10 additionally features high-voltage designation and superior temperature coefficient (±100ppm/°C), making it optimal for demanding automotive environments.

Q: What is the difference between moisture-resistant designation and MSL rating?

A: Moisture-resistant composition refers to the resistor's internal material construction. MSL (Moisture Sensitivity Level) rating indicates sensitivity to moisture during storage and handling. All parts have MSL 1 (Unlimited), meaning they can be stored indefinitely without moisture control. RC3216F5R1CS and RC1206FR-075R1L explicitly specify moisture-resistant composition as an additional feature.

Q: How do packaging formats (Tape & Reel vs. Cut Tape) affect selection?

A: Tape & Reel packaging is optimized for high-volume automated assembly. Cut Tape & Digi-Reel is suitable for lower-volume or mixed-component orders. This is a procurement consideration rather than a technical compatibility factor. All formats are compatible with standard pick-and-place equipment.
