Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMCS1206FT13R3 is determined by strict equivalence across the following critical parameters:

• Resistance value: 13.3 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Package: 1206 (3216 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)
• Moisture sensitivity: MSL 1 (exact match required)

All identified substitute parts meet these criteria. Variations in physical dimensions (length, width, height) within standard tolerances and differences in specific features (anti-sulfur vs. automotive AEC-Q200 vs. moisture resistant) do not affect functional substitutability for applications requiring the specified electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

CRCW120613R3FKEA (Vishay Dale) and RC1206FR-0713R3L (YAGEO) are recommended as primary substitutes. Both maintain Active product status with full ROHS3 compliance and unlimited moisture sensitivity rating. CRCW120613R3FKEA includes automotive AEC-Q200 qualification, suitable for applications requiring automotive-grade reliability. RC1206FR-0713R3L features moisture-resistant construction, appropriate for environments with elevated humidity exposure.

ERJ-8ENF13R3V (Panasonic) is electrically and mechanically equivalent but carries Not For New Designs status. This part remains functionally suitable for replacement in existing designs or legacy applications where Panasonic sourcing is preferred, though new design implementations should prioritize Active-status alternatives.

Frequently Asked Questions (FAQ)

Q: Can CRCW120613R3FKEA replace RMCS1206FT13R3 in any application?

A: Yes. Both parts share identical electrical specifications (13.3 Ohms ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C) and package format (1206). Physical dimension variations (3.20mm x 1.60mm vs. 3.10mm x 1.55mm length and width) fall within standard PCB layout tolerances and do not affect functional compatibility.

Q: What is the significance of the "Not For New Designs" status on ERJ-8ENF13R3V?

A: This designation indicates Panasonic has discontinued active development and promotion of this product line. The part remains electrically and mechanically equivalent and suitable for replacement applications. However, for new circuit designs, Active-status alternatives (CRCW120613R3FKEA or RC1206FR-0713R3L) are preferred to ensure long-term availability and manufacturer support.

Q: Are there differences in reliability between these substitute parts?

A: All four parts meet ROHS3 compliance and MSL 1 ratings. CRCW120613R3FKEA includes AEC-Q200 automotive qualification, indicating enhanced reliability testing for automotive environments. RC1206FR-0713R3L emphasizes moisture resistance. RMCS1206FT13R3 features anti-sulfur construction. These distinctions address specific environmental requirements but do not affect core electrical performance or general-purpose reliability.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. All substitute parts use identical 1206 package footprints. Minor variations in maximum seated height (0.024" to 0.028") are within standard PCB assembly clearance specifications and do not require design modifications.

Q: What compliance certifications apply to all substitute options?

A: All four parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8533.21.0030. MSL 1 rating applies universally, indicating unlimited shelf life under standard storage conditions.
