Substitute Part Grouping Explanation

Substitute parts for the RC6432F1053CS are identified based on strict equivalence of the following parameters:

Electrical Equivalence Requirements:

• Resistance value: 105 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Equivalence Requirements:

• Package type: 2512 (6432 Metric)
• Composition: Thick Film
• Number of terminations: 2

Compliance Requirements:

• RoHS3 compliance
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Unaffected status

The substitute part ERJ-1TNF1053U meets all electrical and mechanical equivalence criteria. Dimensional variations within manufacturing tolerances (length 6.40mm vs 6.30mm, height 0.70mm vs 0.66mm) remain within acceptable PCB assembly parameters for the 2512 package class.

Parameter Comparison

Engineering Selection Recommendations

RC6432F1053CS (Samsung Electro-Mechanics):

• Active product status with ongoing manufacturing support
• Moisture-resistant thick film construction
• Suitable for applications requiring long-term component availability
• Standard commercial-grade qualification

ERJ-1TNF1053U (Panasonic Electronic Components):

• Not For New Designs product status indicates end-of-life phase
• Automotive AEC-Q200 qualification provides enhanced reliability documentation
• Higher inventory availability (5153 pcs vs 692 pcs)
• Suitable for replacement or legacy system maintenance where AEC-Q200 qualification is beneficial

Selection between these parts depends on design phase and application requirements. For new designs, RC6432F1053CS is recommended due to Active status. For applications requiring automotive-grade qualification or legacy system compatibility, ERJ-1TNF1053U remains electrically and mechanically equivalent despite Not For New Designs status.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF1053U directly replace RC6432F1053CS in existing designs?

A: Yes. Both parts meet identical electrical specifications (105 kOhms ±1%, 1W, ±100ppm/°C, -55°C to 155°C), use the same 2512 package, and maintain equivalent RoHS3 and MSL 1 compliance. Dimensional variations (6.40mm vs 6.30mm length, 0.70mm vs 0.66mm height) are within standard PCB assembly tolerances for this package class.

Q: What is the significance of "Not For New Designs" status on ERJ-1TNF1053U?

A: This designation indicates the part is in end-of-life phase and Panasonic does not recommend its use in new product designs. However, the part remains electrically and mechanically equivalent and is suitable for replacement applications, legacy system maintenance, or designs where existing qualification data is already established.

Q: Are there dimensional compatibility concerns between these parts?

A: Dimensional differences are minimal and within manufacturing tolerances for the 2512 package class. Length difference of 0.10mm (6.40mm vs 6.30mm) and height difference of 0.04mm (0.70mm vs 0.66mm) do not affect PCB footprint compatibility or assembly processes for standard surface-mount applications.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both RC6432F1053CS and ERJ-1TNF1053U are ROHS3 compliant, REACH Unaffected, classified as EAR99, and carry MSL 1 (Unlimited) moisture sensitivity ratings. Compliance certifications are equivalent.

Q: What is the difference in packaging between these parts?

A: RC6432F1053CS is supplied in standard packaging format. ERJ-1TNF1053U is supplied in Tape & Reel (TR) format, which is standard for high-volume automated assembly. Both use identical 2512 package specifications.

Q: Can temperature coefficient differences affect substitution?

A: No. Both parts specify identical temperature coefficient of ±100ppm/°C and identical operating temperature range of -55°C to 155°C. Temperature performance is equivalent.
