RMCS1206FT15K4 Equivalent & Substitute Parts

Part Overview

The RMCS1206FT15K4 is a 15.4 kOhms ±1% 0.25W chip resistor in 1206 (3216 Metric) package manufactured by Stackpole Electronics Inc. This thick film resistor features anti-sulfur construction and is designed for general-purpose applications requiring precision resistance values with tight tolerance specifications. The part is currently in active production status. Substitute parts may be required due to supply chain constraints, inventory availability, or application-specific requirements such as automotive qualification or enhanced moisture resistance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMCS1206FT15K4 is determined by the following critical parameters:

• Resistance value: 15.4 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)
• 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 Level: 1 (Unlimited) (exact match required)

All four substitute parts meet these critical parameters. Variations in secondary features such as moisture resistance enhancement, automotive qualification, or packaging format (Tape & Reel vs. Cut Tape) do not affect functional substitutability for standard applications.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are functionally equivalent to the RMCS1206FT15K4 for standard applications. Selection among these alternatives should be based on the following factors:

CR1206-FX-1542ELF (Bourns Inc.) and RC1206FR-0715K4L (YAGEO) are recommended for general-purpose applications. Both parts are in active production status and feature moisture-resistant thick film construction. CR1206-FX-1542ELF offers higher inventory availability (34,661 pcs), while RC1206FR-0715K4L is available in Cut Tape packaging format in addition to Tape & Reel.

CRCW120615K4FKEA (Vishay Dale) is recommended for automotive applications requiring AEC-Q200 qualification. This part is in active production status and meets automotive industry standards.

ERJ-8ENF1542V (Panasonic Electronic Components) is marked as "Not For New Designs" and should not be selected for new product development, despite meeting all electrical and mechanical specifications. This part may be considered only for legacy system maintenance or repair applications where continuity with existing designs is required.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts interchangeably with the RMCS1206FT15K4?

A: Yes, all four substitute parts are electrically and mechanically equivalent. They share identical resistance values (15.4 kOhms), tolerance (±1%), power rating (0.25W), package format (1206), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). Physical dimensions vary slightly within acceptable tolerances for PCB assembly.

Q: What is the difference between the substitute parts?

A: The substitute parts differ in manufacturer, secondary features, and product status. CR1206-FX-1542ELF and RC1206FR-0715K4L feature moisture-resistant construction. CRCW120615K4FKEA includes automotive AEC-Q200 qualification. ERJ-8ENF1542V is marked "Not For New Designs." Packaging format also varies: CR1206-FX-1542ELF, CRCW120615K4FKEA, and ERJ-8ENF1542V are supplied in Tape & Reel format, while RC1206FR-0715K4L is available in Cut Tape & Digi-Reel format.

Q: Should I use ERJ-8ENF1542V for new designs?

A: No. ERJ-8ENF1542V is marked "Not For New Designs" and should not be selected for new product development. Use CR1206-FX-1542ELF, CRCW120615K4FKEA, or RC1206FR-0715K4L instead.

Q: Which substitute part should I choose for automotive applications?

A: CRCW120615K4FKEA (Vishay Dale) is the appropriate choice for automotive applications, as it carries AEC-Q200 qualification. This certification indicates compliance with automotive industry reliability and quality standards.

Q: Are there any physical dimension differences I should be aware of?

A: All parts use the 1206 (3216 Metric) package. Length dimensions range from 0.122" to 0.126" (3.10mm to 3.20mm), and width dimensions range from 0.061" to 0.063" (1.55mm to 1.60mm). Height-seated maximum values range from 0.024" to 0.030" (0.60mm to 0.75mm). These variations are within standard PCB assembly tolerances and do not affect interchangeability.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All parts, including the original RMCS1206FT15K4, have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
