Substitute Part Grouping Explanation

Substitute parts for the CRCW080512K4FKTC are qualified based on the following criteria:

• Resistance value: 12.4 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Packaging format: Tape & Reel (TR)
• Number of terminations: 2
• Moisture sensitivity level: 1 (Unlimited)

All identified substitute parts meet these core electrical and mechanical parameters. Variations in seated height and specific feature sets (such as automotive AEC-Q200 rating or moisture resistance) are noted in the parameter comparison table below.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active products with matching electrical specifications and 0805 package compatibility. Selection among these alternatives should be based on the following factors:

RoHS Compliance: The original CRCW080512K4FKTC is RoHS non-compliant. All substitute parts (CRCW080512K4FKEA, CRCW080512K4FKEAC, ERJ-6ENF1242V, RMCF0805FT12K4, KTR10EZPF1242, CR0805-FX-1242ELF) are ROHS3 compliant, supporting modern procurement requirements.

Automotive Certification: For applications requiring AEC-Q200 automotive qualification, the following parts are certified: CRCW080512K4FKEA, ERJ-6ENF1242V, RMCF0805FT12K4, and KTR10EZPF1242. The CRCW080512K4FKEAC and CR0805-FX-1242ELF do not carry explicit AEC-Q200 ratings in the provided specifications.

Seated Height Variation: Seated height ranges from 0.020" (0.50mm) to 0.028" (0.70mm). For applications with tight vertical clearance constraints, CRCW080512K4FKEA offers the minimum height. For standard PCB assembly, all parts are compatible.

Feature Differentiation: The KTR10EZPF1242 includes high voltage capability in addition to automotive AEC-Q200 rating. The CR0805-FX-1242ELF emphasizes moisture resistance. The CRCW080512K4FKEAC is offered as a manufacturer-recommended variant without explicit automotive features.

Inventory Availability: RMCF0805FT12K4 (208,758 pcs) and CRCW080512K4FKEAC (40,935 pcs) offer the highest stock levels among the alternatives.

Frequently Asked Questions (FAQ)

Q: Can I directly substitute CRCW080512K4FKEA for CRCW080512K4FKTC?

A: Yes. Both parts share identical electrical specifications (12.4 kOhms ±1%, 0.125W, ±100ppm/°C, -55°C to 155°C), package (0805), composition (thick film), and seated height (0.020"). The primary difference is RoHS compliance status. CRCW080512K4FKEA is ROHS3 compliant, whereas CRCW080512K4FKTC is not.

Q: Are all substitute parts suitable for automotive applications?

A: Not all. CRCW080512K4FKEA, ERJ-6ENF1242V, RMCF0805FT12K4, and KTR10EZPF1242 carry AEC-Q200 automotive certification. CRCW080512K4FKEAC and CR0805-FX-1242ELF do not list explicit automotive ratings in the provided specifications. Verify application requirements before selection.

Q: Does seated height variation affect PCB assembly compatibility?

A: Seated height ranges from 0.020" to 0.028" across the substitute parts. For standard PCB assembly processes, this variation is within typical tolerances. However, applications with strict vertical clearance requirements should specify the minimum height variant (CRCW080512K4FKEA at 0.020").

Q: What is the difference between CRCW080512K4FKEA and CRCW080512K4FKEAC?

A: Both are Vishay Dale 12.4 kOhms ±1% 0.125W 0805 resistors with identical electrical performance. CRCW080512K4FKEAC has a slightly higher seated height (0.024" vs 0.020") and does not list automotive AEC-Q200 features. CRCW080512K4FKEA is the automotive-rated variant.

Q: Is the KTR10EZPF1242 a direct substitute or an upgrade?

A: The KTR10EZPF1242 is functionally equivalent in electrical specifications and package. It is differentiated by high voltage capability in addition to automotive AEC-Q200 rating. For standard applications, it is a direct substitute. For high voltage environments, it offers enhanced performance.

Q: Can I use CR0805-FX-1242ELF in place of the original part?

A: Yes, for electrical and mechanical compatibility. The CR0805-FX-1242ELF (Bourns) matches all core specifications: 12.4 kOhms ±1%, 0.125W, 0805 package, ±100ppm/°C, -55°C to 155°C. It emphasizes moisture resistance rather than automotive certification. Confirm application requirements before substitution.

Q: What inventory considerations should guide my selection?

A: RMCF0805FT12K4 (Stackpole) offers the highest stock level at 208,758 pcs. CRCW080512K4FKEAC (Vishay) provides 40,935 pcs. For long-term supply security, higher inventory levels reduce lead time risk. Cross-reference with your procurement timeline and volume requirements.
