RC3216J5R1CS Equivalent & Substitute Parts

Part Overview

The RC3216J5R1CS is a 5.1 Ohm ±5% 0.25W thick film chip resistor manufactured by Samsung Electro-Mechanics in 1206 (3216 Metric) package format. This component is classified as Active product status with moisture resistant characteristics and unlimited moisture sensitivity level (MSL 1). The part is ROHS3 compliant and REACH unaffected, suitable for general-purpose applications requiring standard tolerance resistive elements. Substitute parts are identified based on matching resistance value, power rating, package format, and operating temperature range while accommodating variations in tolerance, temperature coefficient, and application-specific certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3216J5R1CS is determined by the following mandatory parameters:

Core Matching Criteria:

• Resistance value: 5.1 Ohms (exact match required)
• Power rating: 0.25W minimum
• Package format: 1206 (3216 Metric)
• Operating temperature range: -55°C ~ 155°C minimum
• Composition: Thick film
• Terminations: 2-pin configuration
• Compliance: ROHS3 and REACH status

Allowable Variations:

• Tolerance: ±5% or tighter (±1% acceptable as upgrade)
• Temperature coefficient: ±300ppm/°C or better
• Manufacturer: Different manufacturers permitted
• Packaging format: Tape & Reel (TR) or Cut Tape (CT) acceptable
• Features: Additional certifications (AEC-Q200, moisture resistant) permitted

Five substitute parts meet these criteria with identical or superior electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Tolerance):

RC1206JR-075R1L (YAGEO) maintains identical ±5% tolerance specification as the main part RC3216J5R1CS. This substitute is suitable for applications where tolerance matching is required without performance upgrade. Inventory availability is 52,353 pieces.

Upgraded Tolerance Options (±1%):

Three substitute parts offer improved ±1% tolerance specification:

• RC1206FR-075R1L (YAGEO): Provides tighter tolerance with 28,050 pieces in stock. Temperature coefficient improved to ±200ppm/°C. Moisture resistant features maintained.

• RMCF1206FT5R10 (Stackpole Electronics Inc): Offers ±1% tolerance with AEC-Q200 automotive certification. Temperature coefficient ±200ppm/°C. 37,055 pieces available. Height specification 0.028" (0.70mm) maximum.

• KTR18EZPF5R10 (Rohm Semiconductor): Provides superior ±1% tolerance with best-in-class ±100ppm/°C temperature coefficient. AEC-Q200 automotive rated. 5,961 pieces in stock.

Automotive-Rated Alternatives:

RMCF1206JT5R10 (Stackpole Electronics Inc) maintains ±5% tolerance while adding AEC-Q200 automotive qualification. 44,987 pieces available. Suitable for applications requiring automotive-grade components without tolerance upgrade.

All substitute parts are ROHS3 compliant, REACH unaffected, and maintain MSL 1 (Unlimited) moisture sensitivity rating. Product status is Active for all alternatives.

Frequently Asked Questions (FAQ)

Q: Can RC1206JR-075R1L directly replace RC3216J5R1CS in my circuit?

A: Yes. RC1206JR-075R1L is a direct equivalent with identical 5.1 Ohm resistance, ±5% tolerance, 0.25W power rating, 1206 package format, and -55°C ~ 155°C operating temperature range. Both parts are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between ±5% and ±1% tolerance substitutes?

A: Tolerance specifies the allowable deviation from the nominal 5.1 Ohm resistance value. ±5% tolerance permits 4.845 to 5.355 Ohms; ±1% tolerance permits 5.049 to 5.151 Ohms. Applications requiring tighter resistance control should use ±1% alternatives (RC1206FR-075R1L, RMCF1206FT5R10, or KTR18EZPF5R10).

Q: Are there package dimension differences between substitutes?

A: YAGEO parts (RC1206JR-075R1L and RC1206FR-075R1L) have length 0.122" (3.10mm); Samsung, Stackpole, and Rohm parts have length 0.126" (3.20mm). Stackpole and Rohm parts have maximum seated height 0.028" (0.70mm) versus 0.026" (0.65mm) for other substitutes. Verify PCB layout clearance requirements before selection.

Q: What does AEC-Q200 certification mean?

A: AEC-Q200 is an automotive industry qualification standard. RMCF1206FT5R10, RMCF1206JT5R10, and KTR18EZPF5R10 carry this certification, indicating suitability for automotive applications. Non-automotive applications do not require this certification.

Q: Which substitute has the best temperature stability?

A: KTR18EZPF5R10 (Rohm Semiconductor) has the lowest temperature coefficient at ±100ppm/°C, compared to ±200ppm/°C for YAGEO and Stackpole substitutes, and ±300ppm/°C for the main part RC3216J5R1CS. This provides superior resistance stability across the -55°C ~ 155°C operating range.

Q: Can I use a 0.5W resistor instead of 0.25W?

A: The provided substitute list contains only 0.25W (1/4W) rated parts. All substitutes match the main part power rating. Larger power ratings are not included in this equivalency reference.

Q: Are all substitutes available in Tape & Reel packaging?

A: RC1206JR-075R1L, RMCF1206FT5R10, RMCF1206JT5R10, and KTR18EZPF5R10 are supplied in Tape & Reel (TR) format. RC1206FR-075R1L is available in Cut Tape (CT) & Digi-Reel® format. Verify packaging requirements for your procurement process.

Q: Do all substitutes meet ROHS3 compliance?

A: Yes. All five substitute parts are ROHS3 compliant and REACH unaffected, matching the environmental compliance status of RC3216J5R1CS.
