Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3216F1584CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 1.58 MOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters:

• Package format: 1206 (3216 Metric)
• Composition: Thick Film
• Moisture resistance: Required
• Number of terminations: 2

Compliance Parameters:

• RoHS3 compliance
• MSL 1 rating
• REACH unaffected status

The substitute part RC1206FR-071M58L from YAGEO meets all electrical and mechanical requirements. Both parts share identical resistance, tolerance, power rating, temperature coefficient, and operating temperature specifications. Both are thick film, moisture-resistant components in 1206 package format with MSL 1 rating and ROHS3 compliance. Packaging format differs (Tape & Reel for substitute versus standard for main part), which does not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The RC1206FR-071M58L from YAGEO is a direct electrical and mechanical equivalent to the RC3216F1584CS from Samsung Electro-Mechanics. Both parts are active products with current manufacturing status and full compliance certifications (ROHS3, REACH unaffected). Selection between these parts is based on:

Inventory Availability: RC1206FR-071M58L has 1,085 pieces in stock compared to 700 pieces for RC3216F1584CS.

Packaging Requirements: RC1206FR-071M58L is supplied in Tape & Reel format, suitable for automated assembly processes. RC3216F1584CS is supplied in standard packaging. Packaging selection depends on manufacturing process requirements.

Physical Dimensions: Both parts meet 1206 package specifications. Dimensional variations (length 3.20mm vs 3.10mm, height 0.66mm vs 0.65mm) are within standard package tolerances and do not affect PCB layout or assembly compatibility.

Compliance Status: Both parts meet identical regulatory requirements and are suitable for applications requiring ROHS3 compliance and unlimited moisture sensitivity handling.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-071M58L replace RC3216F1584CS in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent with identical resistance, tolerance, power rating, temperature coefficient, and operating temperature range. Both are 1206 package thick film resistors with MSL 1 rating and ROHS3 compliance. PCB layout and circuit performance remain unchanged.

Q: What is the difference between the two parts?

A: The primary differences are manufacturer (Samsung vs YAGEO) and packaging format (standard vs Tape & Reel). Electrical specifications and mechanical dimensions are equivalent. Physical dimensions vary slightly within standard 1206 package tolerances.

Q: Are there any compatibility issues with automated assembly?

A: RC1206FR-071M58L in Tape & Reel format is optimized for automated pick-and-place assembly. RC3216F1584CS in standard packaging may require manual handling or bulk feeder systems. Compatibility depends on assembly equipment capabilities.

Q: Do both parts meet the same compliance standards?

A: Yes. Both RC3216F1584CS and RC1206FR-071M58L are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating. Both are suitable for regulated applications.

Q: What is the temperature coefficient significance?

A: Both parts have ±100ppm/°C temperature coefficient, meaning resistance changes by approximately 0.01% per degree Celsius. This specification is identical for both parts and determines performance stability across the -55°C to 155°C operating range.

Q: Can I mix these parts in the same production batch?

A: Yes. Electrical equivalence allows both parts to function identically in circuit applications. However, manufacturing and quality documentation should reflect the specific part number used in each assembly for traceability and compliance purposes.
