RMCS1206FT38K3 Equivalent & Substitute Parts

Part Overview

The RMCS1206FT38K3 is a 38.3 kOhms ±1% 0.25W chip resistor in 1206 (3216 Metric) package manufactured by Stackpole Electronics Inc. This thick film resistor features anti-sulfur composition and is designed for general-purpose applications requiring precision resistance values with tight tolerance specifications. The part is currently active in production. Substitute parts may be required due to supply chain availability, specific application requirements such as automotive qualification, or design preference for alternative manufacturer offerings.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMCS1206FT38K3 is determined by strict equivalence across the following critical parameters:

• Resistance value: 38.3 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Package: 1206 (3216 Metric) (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• Composition: Thick Film (exact match required)
• Termination count: 2 (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)
• MSL rating: 1 (Unlimited) (exact match required)

All four substitute parts listed meet these electrical and mechanical equivalence criteria. Variations in physical dimensions (length, width, height) and specific feature sets (anti-sulfur, moisture resistant, automotive AEC-Q200) do not affect functional substitutability 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 RMCS1206FT38K3 and are suitable for direct substitution in applications where the specified parameters are required.

CR1206-FX-3832ELF (Bourns Inc.) and RC1206FR-0738K3L (YAGEO) are recommended for general-purpose applications. Both parts are in active production status and feature moisture-resistant thick film composition.

CRCW120638K3FKEA (Vishay Dale) is recommended for automotive applications requiring AEC-Q200 qualification. This part is in active production status and meets automotive reliability standards.

ERJ-8ENF3832V (Panasonic Electronic Components) carries a "Not For New Designs" product status designation. While electrically and mechanically equivalent and currently in stock, this part should not be selected for new design implementations. It may be considered only for legacy system maintenance or replacement applications where the original design specified this component.

Frequently Asked Questions (FAQ)

Q: Can I substitute the RMCS1206FT38K3 with any of the listed parts?

A: Yes. All four substitute parts meet the electrical and mechanical equivalence criteria: 38.3 kOhms ±1% resistance, 0.25W power rating, 1206 package, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, thick film composition, and ROHS3 compliance. Direct substitution is functionally valid.

Q: What is the difference between the anti-sulfur feature of the RMCS1206FT38K3 and the moisture-resistant feature of other substitutes?

A: Anti-sulfur and moisture-resistant are distinct protective features. Anti-sulfur composition protects against sulfur-containing environmental contaminants. Moisture-resistant composition protects against moisture ingress. Both are protective measures but address different environmental stressors. Selection depends on the specific environmental conditions of the application.

Q: Are the automotive AEC-Q200 qualified parts suitable for non-automotive applications?

A: Yes. AEC-Q200 qualification indicates automotive-grade reliability and testing. Parts meeting this standard exceed general-purpose requirements and are suitable for any application requiring the specified electrical and mechanical parameters.

Q: Why is the ERJ-8ENF3832V marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active development and recommends against using this part in new product designs. While the part remains in stock and is functionally equivalent, it should be reserved for legacy system support only.

Q: Do the physical dimension variations affect substitutability?

A: No. All parts conform to the 1206 (3216 Metric) package standard. Minor variations in length, width, and height (within the 1206 specification tolerance) do not affect electrical performance or PCB footprint compatibility.

Q: Which substitute part should I select for maximum supply chain availability?

A: ERJ-8ENF3832V (Panasonic) shows the highest inventory level at 60,432 pieces. However, given its "Not For New Designs" status, CR1206-FX-3832ELF (Bourns) with 19,705 pieces or CRCW120638K3FKEA (Vishay Dale) with 16,924 pieces are preferred for new applications.
