RMCF1210FT953R Equivalent & Substitute Parts

Part Overview

The RMCF1210FT953R is a 953 Ohm ±1% 0.5W chip resistor in 1210 (3225 Metric) package manufactured by Stackpole Electronics Inc. This thick film resistor meets automotive AEC-Q200 qualification and operates across -55°C to 155°C. The part is currently in active production status. Substitute parts are necessary when primary inventory is unavailable, when design flexibility permits alternative qualified manufacturers, or when supply chain optimization is required while maintaining equivalent electrical and mechanical performance.

Substitute Part Grouping Explanation

Substitution of the RMCF1210FT953R is permissible with parts meeting all of the following criteria:

• Resistance value: 953 Ohms
• Tolerance: ±1%
• Power rating: 0.5W (1/2W)
• Package: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1 (Unlimited)
• Physical dimensions: 0.126" L x 0.098" W (3.20mm x 2.50mm), height 0.028" max (0.70mm)
• Terminations: 2

The ERJ-14NF9530U from Panasonic Electronic Components satisfies all substitution criteria and is therefore a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-14NF9530U is electrically and mechanically equivalent to the RMCF1210FT953R. Both parts are ROHS3 compliant, AEC-Q200 qualified, and suitable for automotive applications. The primary distinction is product status: the RMCF1210FT953R maintains active production status, while the ERJ-14NF9530U is designated "Not For New Designs." For new design implementations, the RMCF1210FT953R is the preferred selection. The ERJ-14NF9530U may be used in existing designs or where supply constraints necessitate substitution, provided that design documentation is updated to reflect the manufacturer change.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF9530U be used as a direct replacement for RMCF1210FT953R in automotive applications?

A: Yes. Both parts meet AEC-Q200 automotive qualification, share identical electrical specifications (953 Ohms ±1%, 0.5W), and are packaged in 1210 (3225 Metric) with matching physical dimensions. The substitution is mechanically and electrically valid.

Q: What is the significance of the "Not For New Designs" status on the ERJ-14NF9530U?

A: This designation indicates that Panasonic does not recommend the ERJ-14NF9530U for new product development. Existing designs using this part may continue, but new designs should specify the RMCF1210FT953R or equivalent active-status alternatives.

Q: Are there any differences in thermal performance between these parts?

A: No. Both parts have identical temperature coefficients (±100ppm/°C) and operating temperature ranges (-55°C to 155°C).

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both are MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Can these parts be used interchangeably on the same PCB assembly line?

A: Yes, provided that component procurement and design documentation are updated to reflect any manufacturer change. Both parts are supplied in Tape & Reel (TR) packaging and have identical footprints.
