Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F2151CS is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 2.15 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.125W / 1/8W (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)

Mechanical Equivalence Requirements:

• Package type: 0805 (2012 Metric) (exact match required)
• Number of terminations: 2 (exact match required)
• Composition: Thick Film (exact match required)

Compliance Requirements:

• RoHS3 compliance (all substitutes must maintain compliance)
• Moisture Sensitivity Level: 1 (Unlimited) (all substitutes must maintain MSL 1)

All identified substitute parts meet these criteria. Variations in physical height (seated maximum) and manufacturer-specific features (moisture resistance, automotive qualification, anti-sulfur treatment) do not affect electrical or mechanical substitutability when all core parameters match.

Parameter Comparison

Engineering Selection Recommendations

Active Status Substitutes (Preferred): RC0805FR-072K15L (YAGEO), ERJ-6ENF2151V (Panasonic), AC0805FR-072K15L (YAGEO), and CRCW08052K15FKEA (Vishay Dale) are all classified as Active product status. These parts are currently manufactured and supported by their respective suppliers. All four maintain ROHS3 compliance and MSL 1 rating identical to the primary part.

Automotive-Qualified Alternatives: ERJ-6ENF2151V, AC0805FR-072K15L, and CRCW08052K15FKEA carry AEC-Q200 automotive qualification. These parts are suitable for applications requiring automotive-grade reliability standards while maintaining full electrical and mechanical compatibility with the RC2012F2151CS.

Obsolete Status Consideration: TRR10EZPF2151 (Rohm Semiconductor) is classified as Obsolete product status. While electrically and mechanically equivalent, this part should be selected only when existing inventory is available or when legacy system maintenance requires exact historical part matching. New designs should prioritize Active status alternatives.

Physical Height Variation: Seated maximum heights range from 0.50mm to 0.70mm across all substitutes. PCB design clearance must accommodate the maximum height of 0.70mm (ERJ-6ENF2151V) if multiple substitute sources are anticipated in production.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-072K15L directly replace RC2012F2151CS on existing circuit boards?

A: Yes. RC0805FR-072K15L matches all critical electrical parameters (2.15 kΩ, ±1%, 0.125W, ±100ppm/°C, -55 to 155°C) and mechanical specifications (0805 package, 2 terminations, thick film composition). The 0.60mm seated height is within typical PCB design tolerances for 0805 components.

Q: What is the difference between moisture-resistant and automotive-qualified versions?

A: Moisture-resistant versions (RC2012F2151CS, RC0805FR-072K15L, AC0805FR-072K15L) are designed to resist moisture ingress during storage and operation. Automotive-qualified versions (ERJ-6ENF2151V, AC0805FR-072K15L, CRCW08052K15FKEA) additionally meet AEC-Q200 standards for automotive reliability, including thermal cycling and vibration testing. AC0805FR-072K15L combines both features.

Q: Is TRR10EZPF2151 suitable for new product designs?

A: TRR10EZPF2151 is classified as Obsolete and should not be selected for new designs. Active alternatives (RC0805FR-072K15L, ERJ-6ENF2151V, AC0805FR-072K15L, CRCW08052K15FKEA) provide equivalent performance with ongoing manufacturer support and supply continuity.

Q: Do all substitute parts maintain the same moisture sensitivity level?

A: Yes. All identified substitutes maintain MSL 1 (Unlimited) rating, identical to RC2012F2151CS. This allows unlimited shelf life without moisture baking requirements prior to reflow soldering.

Q: What is the significance of the ±100ppm/°C temperature coefficient across all parts?

A: The ±100ppm/°C temperature coefficient indicates the maximum resistance change per degree Celsius across the -55°C to 155°C operating range. All substitutes match this specification, ensuring equivalent thermal stability and circuit performance across the full temperature range.

Q: Can height differences between substitute parts affect PCB assembly?

A: Height variations (0.50mm to 0.70mm) are within standard 0805 component tolerances. PCB design clearance should accommodate the maximum height of 0.70mm. Reflow soldering profiles and wave soldering parameters remain unchanged across all substitutes.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts are ROHS3 compliant and REACH unaffected, matching the compliance status of RC2012F2151CS. This ensures regulatory compliance for both industrial and consumer applications.
