Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMC1/8K78R7FTP is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Resistance value: 78.7 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
• Moisture sensitivity level: 1 (Unlimited)
• Number of terminations: 2

All substitute parts listed meet these core electrical and mechanical parameters. Variations in physical dimensions (length, width, height) within the 1206 package specification and differences in product features (such as automotive AEC-Q200 qualification or moisture-resistant construction) do not disqualify substitution but indicate application-specific suitability.

Parameter Comparison

Engineering Selection Recommendations

RMC1/8K78R7FTP (Kamaya Inc.) - Primary Reference Active product status with standard thick film construction. Suitable for general-purpose applications without specific automotive or enhanced environmental requirements.

ERJ-8ENF78R7V (Panasonic Electronic Components) Classified as Not For New Designs. Contains automotive AEC-Q200 qualification. Selection of this substitute is limited to legacy system support or replacement applications where AEC-Q200 compliance was originally specified. Not recommended for new design implementations.

RC1206FR-0778R7L (YAGEO) Active product status with ROHS3 compliance and moisture-resistant construction. Suitable for applications requiring enhanced moisture protection and regulatory compliance. Recommended for new designs requiring moisture resistance without automotive qualification.

RMCF1206FT78R7 (Stackpole Electronics Inc) Active product status with ROHS3 compliance and automotive AEC-Q200 qualification. Recommended for automotive applications, harsh environments, or designs requiring AEC-Q200 rated components. Suitable for new design implementations.

Frequently Asked Questions (FAQ)

Q: Can ERJ-8ENF78R7V be used as a direct replacement for RMC1/8K78R7FTP? A: Electrical and mechanical parameters are equivalent. However, ERJ-8ENF78R7V is classified as Not For New Designs. Use only for legacy system replacement or where original design specifications explicitly required this part number.

Q: What is the difference between RC1206FR-0778R7L and RMCF1206FT78R7? A: Both are Active products with identical electrical specifications. RC1206FR-0778R7L features moisture-resistant construction. RMCF1206FT78R7 features automotive AEC-Q200 qualification. Selection depends on application requirements: moisture-critical environments favor RC1206FR-0778R7L; automotive or high-reliability applications favor RMCF1206FT78R7.

Q: Are all substitute parts physically interchangeable in the 1206 package? A: All parts conform to 1206 (3216 Metric) package specification. Minor dimensional variations exist within specification limits (length 0.122" to 0.126", height 0.025" to 0.028"). Verify PCB layout tolerances accommodate maximum dimensions before final selection.

Q: Which substitute part is recommended for new automotive designs? A: RMCF1206FT78R7 (Stackpole Electronics Inc) is the recommended choice for new automotive designs due to Active product status and AEC-Q200 qualification.

Q: Do all substitute parts have the same moisture sensitivity rating? A: All listed parts have MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.

Q: What is the significance of ROHS3 compliance on the substitute parts? A: ROHS3 compliance indicates conformance to Restriction of Hazardous Substances regulations. RC1206FR-0778R7L, ERJ-8ENF78R7V, and RMCF1206FT78R7 are all ROHS3 compliant. Verify your application requirements for regulatory compliance before final selection.
