Substitute Part Grouping Explanation

Substitution eligibility for the RMC1/8-6R19FTP is determined by strict equivalence across the following parameters:

Mandatory Matching Criteria:

• Resistance value: 6.19 Ohms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package type: 1206 (3216 Metric)
• Composition: Thick Film
• Operating temperature range: -55°C ~ 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• Packaging format: Tape & Reel (TR)

Allowable Variations:

• Temperature coefficient: Substitute parts may have different temperature coefficient specifications (-200/+500ppm/°C for main part; ±200ppm/°C for substitutes) provided operating temperature range remains -55°C ~ 155°C
• Physical dimensions: Minor variations in length, width, and height are acceptable within standard 1206 package tolerances
• Additional certifications: Substitute parts may include additional compliance ratings (RoHS3, AEC-Q200) without affecting substitution validity

Two substitute parts meet these criteria: RC1206FR-076R19L (YAGEO) and RMCF1206FT6R19 (Stackpole Electronics Inc).

Parameter Comparison

Engineering Selection Recommendations

RC1206FR-076R19L (YAGEO): This substitute is suitable for applications requiring moisture-resistant thick film construction. YAGEO RC_L series components are ROHS3 compliant and maintain full electrical equivalence to the RMC1/8-6R19FTP. Higher inventory availability (5897 pieces) supports supply chain continuity. Temperature coefficient specification of ±200ppm/°C is tighter than the main part, providing improved thermal stability.

RMCF1206FT6R19 (Stackpole Electronics Inc): This substitute is qualified for automotive applications under AEC-Q200 standard. RMCF series components are ROHS3 compliant and provide automotive-grade reliability. Physical dimensions show minor variation (0.126" L vs. 0.122" L; 0.028" H vs. 0.025" H) within standard 1206 package tolerance. Temperature coefficient of ±200ppm/°C and inventory of 1504 pieces support both standard and automotive circuit implementations.

Both substitutes maintain Active product status and full electrical compatibility with the original RMC1/8-6R19FTP component.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-076R19L replace RMC1/8-6R19FTP in any application?

A: Yes. RC1206FR-076R19L meets all mandatory electrical and mechanical parameters: 6.19 Ohm resistance, ±1% tolerance, 0.25W power rating, 1206 package, thick film composition, -55°C to 155°C operating range, and MSL 1 rating. The moisture-resistant feature and ROHS3 compliance are additional benefits without compatibility restrictions.

Q: What is the difference between the two substitute parts?

A: RC1206FR-076R19L (YAGEO) emphasizes moisture resistance and general-purpose applications. RMCF1206FT6R19 (Stackpole Electronics Inc) is qualified for automotive use under AEC-Q200 standard. Both are electrically equivalent to the main part. Selection depends on application requirements: general industrial use favors YAGEO; automotive applications require Stackpole.

Q: Are there physical dimension differences between the main part and substitutes?

A: Minor variations exist within 1206 package tolerance. RMC1/8-6R19FTP: 0.122" L × 0.063" W, 0.025" H max. RC1206FR-076R19L: 0.122" L × 0.063" W, 0.026" H max. RMCF1206FT6R19: 0.126" L × 0.063" W, 0.028" H max. These differences do not affect PCB layout or circuit performance for standard 1206 footprints.

Q: What is the temperature coefficient difference, and does it matter?

A: RMC1/8-6R19FTP has -200/+500ppm/°C; both substitutes have ±200ppm/°C. The substitute specifications are tighter and more symmetrical, providing better thermal stability. This is a performance improvement, not a limitation.

Q: Are all three parts ROHS3 compliant?

A: RMC1/8-6R19FTP does not specify RoHS status. RC1206FR-076R19L and RMCF1206FT6R19 are both ROHS3 compliant. For applications requiring RoHS compliance, the substitute parts are preferred.

Q: Which substitute should I choose for new designs?

A: Selection is application-dependent. For general-purpose circuits: RC1206FR-076R19L offers moisture resistance and high availability. For automotive circuits: RMCF1206FT6R19 provides AEC-Q200 qualification. Both are electrically and mechanically equivalent to the original part.
