Key Parameters

Substitute Part Grouping Explanation

Substitution validity for the RC3216F12R4CS is determined by strict equivalence across the following parameters:

Electrical Equivalence Requirements:

• Resistance value: 12.4 Ohms (exact match)
• Tolerance: ±1% (exact match)
• Power rating: 0.25W / 1/4W (exact match)
• Temperature coefficient: ±100ppm/°C (exact match)
• Operating temperature range: -55°C ~ 155°C (exact match or wider)

Mechanical Equivalence Requirements:

• Package / Case: 1206 (3216 Metric) (exact match)
• Number of terminations: 2 (exact match)
• Composition: Thick Film (exact match)

Compliance & Environmental Requirements:

• RoHS Status: ROHS3 Compliant (minimum requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match)
• REACH Status: REACH Unaffected (exact match)

All three identified substitute parts meet these criteria and are therefore classified as direct electrical and mechanical equivalents.

Parameter Comparison

Engineering Selection Recommendations

RC1206FR-0712L (YAGEO): This substitute maintains Active product status with full electrical and mechanical equivalence to the RC3216F12R4CS. All critical parameters including resistance, tolerance, power rating, temperature coefficient, and operating range are identical. ROHS3 compliance and MSL 1 rating confirm environmental compatibility. Tape & Reel packaging is suitable for automated assembly processes.

CRCW120612R4FKEA (Vishay Dale): This substitute provides full electrical and mechanical equivalence with Active product status. The component includes AEC-Q200 automotive qualification, which exceeds the base requirement set by the original part. All electrical specifications and environmental ratings are identical to the RC3216F12R4CS. Tape & Reel packaging supports high-volume production environments.

ERJ-8ENF12R4V (Panasonic Electronic Components): This substitute meets all electrical and mechanical equivalence criteria with identical resistance, tolerance, power rating, temperature coefficient, and operating temperature range. AEC-Q200 automotive qualification is included. However, this component carries "Not For New Designs" product status, indicating it is suitable only for legacy system maintenance and repair applications, not for new circuit development.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-0712R4L replace RC3216F12R4CS in all applications?

A: Yes. RC1206FR-0712R4L is electrically and mechanically equivalent across all specified parameters. Both components share identical resistance (12.4 Ohms), tolerance (±1%), power rating (0.25W), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), package format (1206), and compliance certifications (ROHS3, REACH Unaffected, MSL 1). The primary difference is packaging format: RC3216F12R4CS is supplied in bulk, while RC1206FR-0712R4L is supplied in Tape & Reel format.

Q: What is the difference between CRCW120612R4FKEA and the original RC3216F12R4CS?

A: CRCW120612R4FKEA is electrically and mechanically equivalent to RC3216F12R4CS with one addition: AEC-Q200 automotive qualification. All core electrical parameters (12.4 Ohms ±1%, 0.25W, ±100ppm/°C, -55°C ~ 155°C) and environmental ratings (ROHS3, MSL 1) are identical. The AEC-Q200 rating indicates enhanced reliability testing for automotive applications but does not affect general-purpose circuit compatibility.

Q: Why is ERJ-8ENF12R4V marked "Not For New Designs"?

A: ERJ-8ENF12R4V carries "Not For New Designs" status, indicating the manufacturer has discontinued active development and recommends alternative components for new circuit designs. However, the part remains electrically and mechanically equivalent to RC3216F12R4CS and is suitable for replacement in existing systems requiring maintenance or repair.

Q: Are there mechanical dimension differences between these substitutes?

A: Minor dimensional variations exist within the 1206 package specification. RC3216F12R4CS measures 0.126" L x 0.063" W (3.20mm x 1.60mm) with 0.026" maximum seated height. RC1206FR-0712R4L measures 0.122" L x 0.063" W (3.10mm x 1.60mm) with 0.026" maximum seated height. CRCW120612R4FKEA measures 0.126" L x 0.063" W (3.20mm x 1.60mm) with 0.024" maximum seated height. ERJ-8ENF12R4V measures 0.126" L x 0.063" W (3.20mm x 1.60mm) with 0.028" maximum seated height. These variations remain within 1206 package tolerance and do not affect PCB layout or assembly compatibility.

Q: Which substitute is recommended for high-volume automated assembly?

A: RC1206FR-0712R4L, CRCW120612R4FKEA, and ERJ-8ENF12R4V are all supplied in Tape & Reel format, which is standard for automated pick-and-place assembly. RC3216F12R4CS is supplied in bulk format, which requires manual handling or custom reel preparation. For high-volume production, any of the three Tape & Reel substitutes are suitable; selection should be based on availability, cost, and lead time.

Q: Do all substitutes meet the same compliance requirements?

A: Yes. All three substitutes (RC1206FR-0712R4L, CRCW120612R4FKEA, ERJ-8ENF12R4V) are ROHS3 compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the original RC3216F12R4CS. CRCW120612R4FKEA and ERJ-8ENF12R4V include additional AEC-Q200 automotive qualification, which is a superset of the base compliance requirements.
