RMCS1206FT16R9 Equivalent & Substitute Parts

Part Overview

The RMCS1206FT16R9 is a 16.9 Ohm ±1% 0.25W thick film chip resistor in 1206 (3216 Metric) package manufactured by Stackpole Electronics Inc. This component is currently in active production status with anti-sulfur coating for enhanced reliability in harsh environments. Equivalent and substitute parts are necessary when the primary part experiences supply constraints, extended lead times, or when design requirements mandate specific manufacturer certifications such as automotive AEC-Q200 qualification or alternative moisture resistance features.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMCS1206FT16R9 is determined by strict equivalence across the following critical parameters:

• Resistance value: 16.9 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W (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 to 155°C (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

All four substitute parts meet these criteria. Variations in physical dimensions (length, width, height) within the 1206 package specification and differences in secondary features (anti-sulfur coating versus moisture resistance, automotive certification) do not disqualify substitution but may influence selection based on application-specific requirements.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are electrically and mechanically equivalent to the RMCS1206FT16R9 and are suitable for direct replacement in applications where the primary part is unavailable.

CR1206-FX-16R9ELF (Bourns Inc.) is recommended for general-purpose applications requiring moisture-resistant thick film construction. This part maintains active production status and offers high inventory availability (24,289 pcs).

CRCW120616R9FKEA (Vishay Dale) is recommended for automotive applications requiring AEC-Q200 qualification. This part is actively produced and maintains substantial inventory (15,251 pcs).

RC1206FR-0716R9L (YAGEO) is recommended for cost-sensitive applications requiring moisture-resistant construction. This part maintains active production status with adequate inventory (10,639 pcs).

ERJ-8ENF16R9V (Panasonic Electronic Components) carries a "Not For New Designs" status and should be used only when existing designs require continuity or when other substitutes are unavailable. Despite this status, it maintains the highest inventory availability (65,308 pcs) and includes automotive AEC-Q200 certification.

Frequently Asked Questions (FAQ)

Q: Can CR1206-FX-16R9ELF replace RMCS1206FT16R9 in all applications?

A: Yes. Both parts meet identical electrical specifications (16.9 Ohms ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C) and package requirements (1206 3216 Metric). The primary difference is the coating feature: RMCS1206FT16R9 uses anti-sulfur coating while CR1206-FX-16R9ELF uses moisture-resistant coating. Both provide environmental protection suitable for standard PCB assembly.

Q: Is CRCW120616R9FKEA suitable for automotive applications?

A: Yes. CRCW120616R9FKEA carries AEC-Q200 automotive qualification, making it suitable for automotive-grade applications. The RMCS1206FT16R9 does not carry this certification. If automotive qualification is required, CRCW120616R9FKEA or ERJ-8ENF16R9V are appropriate selections.

Q: Why is ERJ-8ENF16R9V marked "Not For New Designs"?

A: This designation indicates that Panasonic has discontinued this part for new design applications. While the part remains electrically equivalent and is currently in stock, it should not be selected for new product development. Use CR1206-FX-16R9ELF, CRCW120616R9FKEA, or RC1206FR-0716R9L for new designs.

Q: Are there physical dimension differences between these parts?

A: Minor variations exist within the 1206 package specification. Length ranges from 0.122" to 0.126" (3.10mm to 3.20mm), width from 0.061" to 0.063" (1.55mm to 1.60mm), and height from 0.024" to 0.030" (0.60mm to 0.75mm). These variations are within standard 1206 package tolerances and do not affect PCB footprint compatibility or electrical performance.

Q: Which substitute offers the best inventory availability?

A: ERJ-8ENF16R9V offers the highest inventory (65,308 pcs), followed by CR1206-FX-16R9ELF (24,289 pcs) and CRCW120616R9FKEA (15,251 pcs). However, inventory levels are subject to change. For new designs, CR1206-FX-16R9ELF or CRCW120616R9FKEA are preferred due to active production status.
