Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMC1/8-3R0JTP is determined by the following critical parameters: resistance value (3 Ohms), package format (1206), power rating (0.25W), composition (thick film), operating temperature range (-55°C ~ 155°C), and MSL rating (1). All identified substitute parts maintain these core electrical and mechanical specifications, ensuring functional compatibility in circuit applications.

Substitute parts are grouped into two tolerance categories:

Tolerance ±5% Substitutes: RC1206JR-073RL (YAGEO) and RMCF1206JT3R00 (Stackpole Electronics Inc) maintain identical tolerance specifications to the main part, providing direct functional equivalence.

Tolerance ±1% Substitutes: RC1206FR-073RL (YAGEO) and RMCF1206FT3R00 (Stackpole Electronics Inc) offer improved tolerance performance, suitable for applications requiring tighter resistance accuracy while maintaining all other electrical and mechanical parameters.

All substitute parts operate within the specified temperature range, maintain MSL 1 rating, and are packaged in Tape & Reel format identical to the main part.

Parameter Comparison

Engineering Selection Recommendations

Direct Functional Replacement (±5% Tolerance): RC1206JR-073RL and RMCF1206JT3R00 provide direct functional equivalence to the RMC1/8-3R0JTP. Both parts maintain identical resistance, tolerance, power rating, and package specifications. RC1206JR-073RL offers moisture-resistant thick film construction with ROHS3 compliance. RMCF1206JT3R00 includes automotive AEC-Q200 qualification, suitable for applications requiring automotive-grade component reliability.

Enhanced Tolerance Selection (±1% Tolerance): RC1206FR-073RL and RMCF1206FT3R00 provide improved tolerance performance at ±1%, reducing resistance variation in circuit applications. RC1206FR-073RL combines moisture-resistant construction with ROHS3 compliance. RMCF1206FT3R00 includes automotive AEC-Q200 qualification with enhanced tolerance specifications.

Compliance Considerations: All substitute parts maintain REACH Unaffected status and EAR99 ECCN classification identical to the main part. YAGEO and Stackpole Electronics Inc substitute parts carry ROHS3 compliance certification. Stackpole Electronics Inc parts include AEC-Q200 automotive qualification, appropriate for automotive and high-reliability applications.

Temperature Coefficient: The main part specifies -200/+500ppm/°C temperature coefficient. All substitute parts specify ±200ppm/°C, representing improved temperature stability across the operating range.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-073RL or RMCF1206FT3R00 be used as direct replacements for RMC1/8-3R0JTP?

A: Yes, both parts are functionally compatible. These ±1% tolerance variants maintain identical resistance value (3 Ohms), power rating (0.25W), package format (1206), and operating temperature range (-55°C ~ 155°C). The improved tolerance specification provides tighter resistance accuracy without affecting circuit compatibility.

Q: What is the difference between YAGEO and Stackpole Electronics Inc substitute options?

A: YAGEO RC1206 series parts (RC1206FR-073RL and RC1206JR-073RL) feature moisture-resistant thick film construction with ROHS3 compliance. Stackpole Electronics Inc RMCF series parts (RMCF1206FT3R00 and RMCF1206JT3R00) include automotive AEC-Q200 qualification, suitable for automotive applications requiring enhanced reliability standards.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes, all identified substitute parts are supplied in Tape & Reel (TR) packaging format, matching the main part's packaging specification for automated assembly compatibility.

Q: Does tolerance selection affect circuit performance?

A: Tolerance selection depends on circuit requirements. The ±5% tolerance variants (RC1206JR-073RL and RMCF1206JT3R00) match the main part's tolerance specification. The ±1% tolerance variants (RC1206FR-073RL and RMCF1206FT3R00) provide improved resistance accuracy, beneficial for precision circuits requiring tighter component tolerances.

Q: Are substitute parts RoHS compliant?

A: All substitute parts carry ROHS3 compliance certification. The main part RoHS status is not specified in the provided data.

Q: What is the MSL rating for all parts?

A: All parts, including the main part and all substitutes, maintain MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage and handling.
