Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC6432F1052CS are qualified based on the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Resistance value: 10.5 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Package: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1 (Unlimited)

All identified substitute parts meet these core electrical and environmental specifications. Dimensional variations within the 2512 package specification are acceptable for direct substitution. Product status and application-specific certifications (such as AEC-Q200 for automotive use) are noted but do not preclude substitution in non-automotive applications.

Parameter Comparison

Engineering Selection Recommendations

CRCW251210K5FKEG (Vishay Dale) is the primary substitute for the RC6432F1052CS. This part maintains Active product status and carries AEC-Q200 automotive qualification. All electrical parameters, package specifications, and environmental ratings are equivalent. The Tape & Reel packaging format is standard for high-volume production environments.

ERJ-1TNF1052U (Panasonic Electronic Components) is a secondary substitute option. While all electrical and mechanical specifications match the original part, this component is designated as "Not For New Designs." This status indicates the manufacturer is phasing out this part number. Use of ERJ-1TNF1052U is acceptable for replacement or repair of existing assemblies but is not recommended for new product development.

Selection between CRCW251210K5FKEG and ERJ-1TNF1052U should be based on design phase (new development versus maintenance) and supply chain availability. Both parts are functionally equivalent to the RC6432F1052CS for applications within the specified electrical and thermal operating parameters.

Frequently Asked Questions (FAQ)

Q: Can CRCW251210K5FKEG replace RC6432F1052CS in existing designs?

A: Yes. The CRCW251210K5FKEG meets all electrical specifications (10.5 kOhms ±1%, 1W), operates across the same temperature range (-55°C to 155°C), and is packaged in the identical 2512 (6432 Metric) form factor. Direct substitution is supported.

Q: What is the significance of the "Not For New Designs" status on ERJ-1TNF1052U?

A: This designation indicates Panasonic has discontinued active development and promotion of this part number. While the component remains functionally equivalent and available in inventory, it should not be selected for new product designs. Use ERJ-1TNF1052U only for repair, rework, or maintenance of existing assemblies.

Q: Are there dimensional differences between the substitute parts?

A: Minor dimensional variations exist within the 2512 package specification. RC6432F1052CS measures 0.248" L × 0.126" W (6.30mm × 3.20mm) with 0.026" max height. CRCW251210K5FKEG measures 0.248" L × 0.124" W (6.30mm × 3.15mm) with 0.028" max height. ERJ-1TNF1052U measures 0.252" L × 0.126" W (6.40mm × 3.20mm) with 0.028" max height. These variations remain within standard 2512 package tolerances and do not affect PCB layout or assembly compatibility.

Q: Do the substitute parts require different soldering or handling procedures?

A: No. All substitute parts share identical composition (thick film), moisture sensitivity level (MSL 1), and RoHS compliance status. Standard SMD assembly and soldering procedures applicable to the RC6432F1052CS apply equally to CRCW251210K5FKEG and ERJ-1TNF1052U.

Q: Which substitute part should be selected for automotive applications?

A: CRCW251210K5FKEG carries AEC-Q200 automotive qualification. If automotive compliance is required, CRCW251210K5FKEG is the appropriate selection. ERJ-1TNF1052U also carries AEC-Q200 rating but is not recommended for new automotive designs due to its "Not For New Designs" status.
