Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: resistance value (953 Ohms), tolerance (±1%), power rating (0.125W), package type (0805), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and moisture sensitivity level (MSL 1). All identified substitutes maintain these core electrical and mechanical specifications. Compliance certifications (RoHS, REACH, AEC-Q200) and product status are secondary factors that influence selection based on application requirements and supply chain considerations.

Parameter Comparison

Engineering Selection Recommendations

CRCW0805953RFKEA (Vishay Dale) is the primary substitute for RMCF0805FT953R. Both parts are ROHS3 compliant, AEC-Q200 rated, and active in production. The CRCW0805953RFKEA has a lower seated height (0.020" vs 0.026"), which may provide advantages in space-constrained designs.

ERJ-6ENF9530V (Panasonic Electronic Components) is an alternative substitute with AEC-Q200 rating and ROHS3 compliance. This part has the highest inventory availability (55,306 pcs) and a slightly higher seated height (0.028").

CRCW0805953RFKTA (Vishay Dale) shares identical electrical specifications but is RoHS non-compliant and REACH affected, limiting its use in applications requiring regulatory compliance.

MCR10ERTF9530 (Rohm Semiconductor) is discontinued at DiGi Electronics and lacks AEC-Q200 certification, making it unsuitable for new automotive designs despite ROHS3 compliance.

RC0805FR-07953RL (YAGEO) is active and ROHS3 compliant but does not carry AEC-Q200 rating. This part includes moisture-resistant features and is suitable for non-automotive applications requiring the specified electrical parameters.

Frequently Asked Questions (FAQ)

Q: Can CRCW0805953RFKEA directly replace RMCF0805FT953R in automotive applications?

A: Yes. Both parts meet AEC-Q200 automotive standards, maintain identical electrical specifications (953 Ohms ±1%, 0.125W, ±100ppm/°C), and are ROHS3 compliant. The lower seated height of CRCW0805953RFKEA (0.020" vs 0.026") is mechanically compatible with 0805 package footprints.

Q: What is the difference between CRCW0805953RFKEA and CRCW0805953RFKTA?

A: Both are Vishay Dale CRCW series resistors with identical electrical specifications. CRCW0805953RFKEA is ROHS3 compliant and REACH unaffected, while CRCW0805953RFKTA is RoHS non-compliant and REACH affected. For applications requiring regulatory compliance, CRCW0805953RFKEA is the appropriate choice.

Q: Is ERJ-6ENF9530V suitable for automotive applications?

A: Yes. ERJ-6ENF9530V is AEC-Q200 rated and ROHS3 compliant, meeting automotive qualification requirements. It maintains all required electrical specifications and operates across the full -55°C to 155°C temperature range.

Q: Why is MCR10ERTF9530 not recommended as a substitute?

A: MCR10ERTF9530 is discontinued at DiGi Electronics and does not carry AEC-Q200 certification. For new designs requiring automotive-grade components, this part is not suitable despite meeting basic electrical specifications.

Q: Can RC0805FR-07953RL be used in place of RMCF0805FT953R?

A: RC0805FR-07953RL matches all electrical specifications and is ROHS3 compliant. However, it lacks AEC-Q200 certification. Use this part only in non-automotive applications or where automotive qualification is not required. The moisture-resistant feature provides additional protection in humid environments.

Q: Are all substitute parts available in the same packaging format?

A: All substitute parts are available in 0805 (2012 Metric) package. Packaging options vary: RMCF0805FT953R, CRCW0805953RFKEA, CRCW0805953RFKTA, ERJ-6ENF9530V, and RC0805FR-07953RL are supplied in Tape & Reel (TR). MCR10ERTF9530 is supplied in Cut Tape (CT) & Digi-Reel format.

Q: What is the significance of Moisture Sensitivity Level (MSL) 1?

A: MSL 1 indicates unlimited shelf life without moisture baking requirements. All listed parts, including the main part and substitutes, carry MSL 1 rating, ensuring consistent handling and storage procedures across all options.
