RMCS1206FT750R Equivalent & Substitute Parts

Part Overview

The RMCS1206FT750R is a 750 Ohm ±1% 0.25W (1/4W) chip resistor in 1206 (3216 Metric) package manufactured by Stackpole Electronics Inc. This anti-sulfur thick film resistor operates across -55°C to 155°C and is ROHS3 compliant. Equivalent and substitute parts are necessary when the primary part is unavailable, when design requirements demand specific certifications such as AEC-Q200 automotive qualification, or when enhanced performance characteristics such as moisture resistance or higher power ratings are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMCS1206FT750R is determined by the following core parameters:

• Resistance Value: 750 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Package / Case: 1206 (3216 Metric) (exact match required)
• Power Rating: 0.25W minimum (equal or higher acceptable)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C minimum (equal or wider acceptable)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)
• RoHS Compliance: ROHS3 Compliant (preferred for regulatory alignment)

Substitute parts meeting these criteria are functionally interchangeable. Additional certifications such as AEC-Q200 automotive qualification and moisture-resistant features represent enhanced specifications that do not preclude substitution but indicate suitability for specific application environments.

Parameter Comparison

Engineering Selection Recommendations

Preferred Substitutes (Active Status, ROHS3 Compliant)

RMCF1206FT750R, CRCW1206750RFKEA, and CRCW1206750RFKTA from Stackpole and Vishay Dale are direct substitutes with automotive AEC-Q200 certification. These parts maintain full electrical and mechanical compatibility while providing enhanced qualification for automotive applications.

AC1206FR-07750RL and RC1206FR-07750RL from YAGEO offer moisture-resistant thick film construction in addition to AEC-Q200 certification, suitable for environments with elevated humidity exposure.

CR1206-FX-7500ELF from Bourns Inc. provides moisture-resistant construction without automotive certification, appropriate for general industrial applications requiring moisture protection.

Conditional Substitutes

CRCW1206750RFKEAHP from Vishay Dale features 0.75W power rating with pulse-withstanding capability. This part is suitable only when circuit design permits higher power dissipation and pulse immunity is required.

Not Recommended for New Designs

ERJ-8ENF7500V from Panasonic is marked "Not For New Designs" and should be used only for legacy system maintenance or repair applications where design continuity is mandatory.

CRCW1206750RFKTA from Vishay Dale is RoHS non-compliant and REACH-affected, making it unsuitable for applications subject to regulatory compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can RMCF1206FT750R replace RMCS1206FT750R directly?

A: Yes. Both parts share identical electrical specifications (750 Ohms ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C) and package (1206). RMCF1206FT750R adds automotive AEC-Q200 certification, which does not affect basic functionality but indicates suitability for automotive environments.

Q: What is the difference between CRCW1206750RFKEA and CRCW1206750RFKEAHP?

A: Both are 750 Ohm ±1% resistors in 1206 package from Vishay Dale with AEC-Q200 certification. CRCW1206750RFKEAHP has 0.75W power rating compared to 0.25W in CRCW1206750RFKEA. The higher power rating allows greater current handling and pulse withstanding capability. Selection depends on circuit power dissipation requirements.

Q: Are moisture-resistant variants (AC1206FR-07750RL, RC1206FR-07750RL, CR1206-FX-7500ELF) necessary?

A: Moisture-resistant variants are functionally equivalent to the base RMCS1206FT750R. Selection of moisture-resistant types is application-dependent. Use moisture-resistant variants in high-humidity environments, potted assemblies, or applications where condensation exposure is anticipated.

Q: Why is ERJ-8ENF7500V marked "Not For New Designs"?

A: Panasonic has discontinued active development of the ERJ-8EN series. While the part remains electrically and mechanically compatible, new designs should specify active-status alternatives such as RMCF1206FT750R, CRCW1206750RFKEA, or AC1206FR-07750RL to ensure long-term supply availability and manufacturer support.

Q: Is CRCW1206750RFKTA suitable for new designs?

A: No. CRCW1206750RFKTA is RoHS non-compliant and REACH-affected. Regulatory requirements in most markets mandate ROHS3 compliance. Use CRCW1206750RFKEA or CRCW1206750RFKTA alternatives instead.

Q: Can I use any substitute part without PCB layout changes?

A: All substitute parts maintain the 1206 (3216 Metric) package footprint. Physical dimensions vary slightly (length 0.122" to 0.126", height 0.024" to 0.030"), but these variations fall within standard PCB design tolerances for 1206 components. No layout modifications are required.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel packaging is supplied on continuous carrier tape for automated assembly. Cut Tape & Digi-Reel packaging is supplied in smaller quantities on cut tape segments. Both formats contain identical components; packaging selection depends on production volume and assembly equipment compatibility.
