Substitute Part Grouping Explanation

Substitution eligibility for the CRCW1206787RFKEAC is determined by strict equivalence across the following parameters:

• Resistance value: 787 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W, 1/4W (exact match required)
• Package: 1206 (3216 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)
• RoHS compliance: ROHS3 Compliant (minimum requirement)
• Moisture sensitivity: MSL 1 (Unlimited) (exact match required)

All substitute parts listed below meet these criteria. Additional features such as automotive AEC-Q200 qualification represent enhancements that do not preclude substitution but may offer improved reliability for specific applications.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are electrically and mechanically equivalent to the CRCW1206787RFKEAC based on the core parameters: resistance, tolerance, power rating, package, composition, temperature coefficient, and operating temperature range.

For general-purpose applications with no automotive requirements, the CRCW1206787RFKEAC (Vishay Dale) remains the primary choice as an active product.

The MCR18ERTF7870 (Rohm) is electrically equivalent but is discontinued at DiGi Electronics, limiting availability for new designs.

The KTR18EZPF7870 (Rohm) and RMCF1206FT787R (Stackpole) are both active products with AEC-Q200 automotive qualification. These parts are suitable for applications requiring automotive-grade reliability and are available in higher inventory quantities. Selection between these two should be based on supply chain preference and lead time requirements.

Frequently Asked Questions (FAQ)

Q: Can MCR18ERTF7870 be used as a direct replacement for CRCW1206787RFKEAC?

A: Yes. Both parts share identical electrical specifications (787 Ohms ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C) and package (1206). However, MCR18ERTF7870 is discontinued at DiGi Electronics, which may affect long-term availability.

Q: What is the difference between KTR18EZPF7870 and RMCF1206FT787R?

A: Both parts are electrically equivalent to CRCW1206787RFKEAC and carry AEC-Q200 automotive qualification. The primary difference is manufacturer: KTR18EZPF7870 is from Rohm Semiconductor, while RMCF1206FT787R is from Stackpole Electronics Inc. Physical dimensions are slightly different (KTR: 0.126" L x 0.063" W; RMCF: 0.126" L x 0.063" W), and maximum seated height varies (KTR: 0.026"; RMCF: 0.028").

Q: Are automotive-qualified parts (AEC-Q200) required for my application?

A: AEC-Q200 qualification is required only for automotive applications. For non-automotive applications, the standard CRCW1206787RFKEAC is sufficient. Automotive-qualified alternatives (KTR18EZPF7870, RMCF1206FT787R) may be used in non-automotive applications without issue.

Q: Can I use these parts interchangeably on the same PCB?

A: Yes, all listed parts are mechanically compatible with 1206 (3216 Metric) footprints. Physical dimension variations are within standard PCB assembly tolerances.

Q: What does MSL 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling, making it suitable for standard manufacturing environments.
