Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMC1/8K91R0FTP is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Resistance value: 91 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 three substitute parts meet these core electrical and mechanical parameters. Differences exist only in manufacturer identity, product status classification, and optional certifications (such as AEC-Q200 automotive qualification or moisture-resistant features), which do not affect functional equivalence for standard applications.

Parameter Comparison

Engineering Selection Recommendations

RC1206FR-0791RL (YAGEO) is the primary substitute for general-purpose applications. This part maintains Active product status, carries ROHS3 compliance, and includes moisture-resistant features. Dimensional specifications (0.122" L x 0.063" W, 0.026" max height) align with the original part.

RMCF1206FT91R0 (Stackpole Electronics Inc) is suitable for automotive applications requiring AEC-Q200 qualification. This part is Active status with ROHS3 compliance. Dimensional specifications (0.126" L x 0.063" W, 0.028" max height) represent a minor variation within acceptable mechanical tolerances for 1206 package footprints.

ERJ-8ENF91R0V (Panasonic Electronic Components) carries AEC-Q200 automotive qualification but is classified as Not For New Designs. This designation indicates the manufacturer is discontinuing this product line. Selection of this part is not recommended for new circuit designs, though it remains electrically and mechanically equivalent for existing applications requiring automotive-grade components.

All three substitutes are electrically and mechanically interchangeable with the RMC1/8K91R0FTP based on the provided parameters.

Frequently Asked Questions (FAQ)

Q: Can ERJ-8ENF91R0V be used as a direct replacement for RMC1/8K91R0FTP?

A: Yes, ERJ-8ENF91R0V is electrically and mechanically equivalent. However, its "Not For New Designs" status indicates Panasonic is phasing out this product line. For new circuit designs, RC1206FR-0791RL or RMCF1206FT91R0 are preferred alternatives.

Q: What is the difference between the automotive-qualified parts and the standard part?

A: RMCF1206FT91R0 and ERJ-8ENF91R0V carry AEC-Q200 automotive certification, indicating qualification for automotive temperature cycling and reliability testing. The RMC1/8K91R0FTP and RC1206FR-0791RL do not carry this certification. Selection depends on application requirements.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist. RMC1/8K91R0FTP and RC1206FR-0791RL measure 0.122" L x 0.063" W with 0.025-0.026" max height. ERJ-8ENF91R0V and RMCF1206FT91R0 measure 0.126" L x 0.063" W with 0.028" max height. These variations are within standard 1206 package tolerances and do not affect PCB footprint compatibility.

Q: Does RC1206FR-0791RL moisture-resistant feature provide additional protection?

A: RC1206FR-0791RL includes moisture-resistant construction. All four parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity limitations. The moisture-resistant feature in RC1206FR-0791RL provides enhanced durability in high-humidity environments but does not change the MSL classification.

Q: Which substitute should be selected for cost optimization?

A: Selection based on cost requires current pricing and availability data not provided in this reference. Consult supplier inventory and pricing for RC1206FR-0791RL (35103 pcs available), RMCF1206FT91R0 (11620 pcs available), or ERJ-8ENF91R0V (68824 pcs available).

Q: Are all parts REACH compliant?

A: Yes, all four parts carry REACH Unaffected status, indicating compliance with REACH regulations.
