Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMC1/8K8450FTP is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Resistance value: 845 Ohms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Number of terminations: 2
• Moisture sensitivity level: 1 (Unlimited)

All substitute parts listed meet these electrical and mechanical specifications. Variations in physical dimensions (length, width, height) within standard 1206 package tolerances do not affect functional substitution. Additional features such as automotive AEC-Q200 qualification or moisture-resistant construction represent enhanced capabilities that do not preclude substitution but may be required for specific applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status): RC1206FR-07845RL (YAGEO) and RMCF1206FT845R (Stackpole) are recommended as primary substitutes. Both maintain Active product status, ensuring long-term availability and supply chain stability. RC1206FR-07845RL provides moisture-resistant construction. RMCF1206FT845R includes automotive AEC-Q200 qualification for applications requiring automotive-grade reliability.

Secondary Selection (Compliance-Dependent): ERJ-8ENF8450V (Panasonic) is electrically and mechanically equivalent but carries "Not For New Designs" status. This part is suitable only for legacy system maintenance or replacement applications where the original specification explicitly requires Panasonic components.

Discontinued Status: MCR18ERTF8450 (Rohm) is discontinued at DiGi Electronics. This part should not be selected for new designs or long-term production requirements. Use only when existing inventory is available and supply continuity is not a concern.

Compliance Considerations: All substitute parts are REACH Unaffected and classified as EAR99 for export control purposes. YAGEO and Stackpole parts are ROHS3 Compliant. Panasonic and Rohm parts are also ROHS3 Compliant. No compliance barriers exist for substitution within this group.

Frequently Asked Questions (FAQ)

Q: Can ERJ-8ENF8450V replace RMC1/8K8450FTP in new designs? A: ERJ-8ENF8450V is electrically and mechanically equivalent but carries "Not For New Designs" status. It is suitable only for replacement or legacy applications. For new designs, select RC1206FR-07845RL or RMCF1206FT845R.

Q: What is the difference between RC1206FR-07845RL and RMCF1206FT845R? A: Both are functionally equivalent 845 Ohm ±1% 1206 thick film resistors. RC1206FR-07845RL (YAGEO) features moisture-resistant construction. RMCF1206FT845R (Stackpole) includes automotive AEC-Q200 qualification. Selection depends on application requirements: moisture-critical environments favor YAGEO; automotive applications favor Stackpole.

Q: Are physical dimension variations between substitute parts significant? A: Physical dimensions vary slightly within standard 1206 package tolerances. RMC1/8K8450FTP and RC1206FR-07845RL measure 0.122" L x 0.063" W. ERJ-8ENF8450V and RMCF1206FT845R measure 0.126" L x 0.063" W. These variations are within standard 1206 specifications and do not affect PCB layout compatibility or functional performance.

Q: Is MCR18ERTF8450 available for procurement? A: MCR18ERTF8450 is discontinued at DiGi Electronics. Existing inventory may be available through alternative distributors, but long-term supply cannot be guaranteed. For new production, select RC1206FR-07845RL or RMCF1206FT845R.

Q: Do all substitute parts have the same moisture sensitivity rating? A: Yes. All parts listed, including the main part RMC1/8K8450FTP, carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.

Q: Which substitute part should I select for automotive applications? A: RMCF1206FT845R (Stackpole) includes automotive AEC-Q200 qualification and is recommended for automotive applications. This part is Active status and ROHS3 Compliant.
