Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F155CS is determined by strict equivalence across the following parameters:

Mandatory Equivalence Parameters:

• Resistance value: 1.5 MOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.125W / 1/8W (exact match required)
• Package: 0805 (2012 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• RoHS3 compliance (required for regulatory equivalence)
• MSL 1 rating (required for moisture protection equivalence)

Variable Parameters Allowing Substitution:

• Temperature coefficient: ±100ppm/°C or ±200ppm/°C (both acceptable)
• Manufacturer identity (multiple qualified sources)
• Product features: Standard, Automotive AEC-Q200, High Voltage, or Anti-Sulfur variants
• Packaging format: Tape & Reel (TR) or Cut Tape (CT)
• Physical height: 0.020" to 0.028" seated height (within 0805 package specification)

Substitute parts are categorized as Direct (functionally identical to main part), Upgrade (enhanced certifications or features), or Similar (alternative manufacturers with equivalent specifications).

Parameter Comparison

Engineering Selection Recommendations

For Standard Industrial Applications: Select RC0805FR-071M5L (YAGEO) as the primary direct substitute. This part maintains identical electrical specifications and moisture-resistant characteristics with Active product status. Inventory availability is 2012 pieces.

For Automotive Applications: Select AC0805FR-071M5L (YAGEO) or CRCW08051M50FKEA (Vishay Dale) when AEC-Q200 automotive qualification is required. Both parts are Active status with RoHS3 compliance. AC0805FR-071M5L provides moisture-resistant features matching the original specification. CRCW08051M50FKEA offers higher inventory availability (47297 pieces) with Cut Tape & Digi-Reel packaging option.

For High-Voltage Circuit Requirements: Select KTR10EZPF1504 (Rohm Semiconductor) or RCV08051M50FKEA (Vishay Dale). KTR10EZPF1504 combines automotive AEC-Q200 qualification with high-voltage capability. RCV08051M50FKEA provides high-voltage specification in Cut Tape format with 17391 pieces available.

For Temperature-Stable Applications: Select parts with ±100ppm/°C temperature coefficient (RC0805FR-071M5L, KTR10EZPF1504, AC0805FR-071M5L, CRCW08051M50FKEA, ERJ-6ENF1504V, RCV08051M50FKEA). RMCF0805FT1M50 has ±200ppm/°C coefficient and is acceptable only when broader temperature stability is acceptable.

Avoid: CRCW08051M50FKEB (Discontinued at DiGi Electronics) and TRR10EZPF1504 (Obsolete status) for new designs or long-term supply requirements.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-071M5L directly replace RC2012F155CS without circuit modification?

A: Yes. RC0805FR-071M5L is electrically and mechanically equivalent. Both parts have 1.5 MOhms ±1% resistance, 0.125W power rating, 0805 package, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. Physical height difference (0.024" vs 0.026" seated) is within 0805 package tolerance and does not affect PCB assembly.

Q: What is the difference between CRCW08051M50FKEA and CRCW08051M50FKEB?

A: Both parts are electrically identical 1.5 MOhms ±1% 0.125W 0805 resistors with Automotive AEC-Q200 qualification. The primary difference is packaging format: FKEA uses Cut Tape & Digi-Reel format, while FKEB uses Tape & Reel format. FKEB is discontinued at DiGi Electronics; FKEA remains Active. Select FKEA for new applications.

Q: Why does RMCF0805FT1M50 have ±200ppm/°C temperature coefficient instead of ±100ppm/°C?

A: RMCF0805FT1M50 is manufactured by Stackpole Electronics with different thick film composition technology. The ±200ppm/°C specification is within acceptable tolerance for most applications but indicates broader temperature drift. Use this part only when circuit design tolerates ±200ppm/°C or when other qualified alternatives are unavailable.

Q: Is AC0805FR-071M5L suitable for non-automotive applications?

A: Yes. AC0805FR-071M5L exceeds the specification of RC2012F155CS by including Automotive AEC-Q200 qualification and moisture-resistant features. It is fully compatible with standard industrial applications and provides enhanced reliability margin.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 rating indicates the component requires no special moisture protection during storage or handling. Both the main part RC2012F155CS and all substitute parts carry MSL 1 rating, meaning they can be stored and handled under standard warehouse conditions without desiccant packing or time-limited shelf life restrictions.

Q: Can RCV08051M50FKEA (High Voltage variant) be used in standard circuits?

A: Yes. RCV08051M50FKEA maintains the same 1.5 MOhms ±1% 0.125W electrical specification as the main part. The high-voltage feature is an additional capability that does not restrict use in standard circuits. This part is suitable for both standard and high-voltage applications.

Q: Why is TRR10EZPF1504 listed if it is Obsolete?

A: TRR10EZPF1504 is included for reference in legacy system documentation and reverse-engineering applications. For new designs or production, this part must not be selected due to obsolete status. Use Active-status alternatives such as KTR10EZPF1504 from the same manufacturer.

Q: What packaging format should be selected for automated assembly?

A: Tape & Reel (TR) format is standard for automated pick-and-place assembly. All substitute parts except CRCW08051M50FKEA and RCV08051M50FKEA are available in Tape & Reel format. CRCW08051M50FKEA offers Cut Tape & Digi-Reel as alternative; CRCW08051M50FKEB provides Tape & Reel but is discontinued.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry RoHS3 Compliant status, matching the environmental compliance requirement of RC2012F155CS. All parts are also REACH Unaffected and classified as EAR99 for export control purposes.
