Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F30R9CS is determined by strict alignment with the following core parameters:

Electrical Parameters (Non-negotiable):

• Resistance: 30.9 Ohms (exact match required)
• Tolerance: ±1% (substitute must not exceed this tolerance)
• Power Rating: 1W (substitute must equal or exceed)
• Temperature Coefficient: ±100ppm/°C (substitute must equal or be lower)
• Operating Temperature Range: -55°C to 155°C (substitute must cover this range)

Mechanical Parameters (Non-negotiable):

• Package / Case: 2512 (6432 Metric) (exact match required for PCB footprint compatibility)
• Composition: Thick Film (determines electrical behavior)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (regulatory requirement)
• Moisture Sensitivity Level: MSL 1 (handling specification)

The ERJ-1TNF30R9U from Panasonic Electronic Components meets all substitution criteria. While this part carries an automotive AEC-Q200 qualification and is marked as "Not For New Designs," it maintains full electrical and mechanical compatibility with the RC6432F30R9CS.

Parameter Comparison

Engineering Selection Recommendations

Primary Component (RC6432F30R9CS): The RC6432F30R9CS remains the preferred selection for new designs. It is in active production status, carries moisture-resistant specifications, and maintains full ROHS3 compliance. With 1116 pieces in current inventory, supply availability is established.

Substitute Component (ERJ-1TNF30R9U): The ERJ-1TNF30R9U from Panasonic is electrically and mechanically equivalent to the RC6432F30R9CS. This substitute is appropriate for applications requiring component replacement or when supply of the primary part is unavailable. The part carries AEC-Q200 automotive qualification, which exceeds the requirements of the primary component.

Product Status Consideration: The ERJ-1TNF30R9U is marked "Not For New Designs." This designation indicates Panasonic is not recommending this part for new product development. However, it remains suitable for replacement, repair, and legacy system applications where the RC6432F30R9CS is unavailable.

Dimensional Tolerance: Minor dimensional variations exist between the two parts. The ERJ-1TNF30R9U measures 0.252" L x 0.126" W (6.40mm x 3.20mm) with a maximum seated height of 0.028" (0.70mm), compared to the RC6432F30R9CS at 0.248" L x 0.126" W (6.30mm x 3.20mm) with a maximum seated height of 0.026" (0.66mm). These variations remain within standard PCB design tolerances for the 2512 package footprint.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-1TNF30R9U be used as a direct replacement for the RC6432F30R9CS?

A: Yes. The ERJ-1TNF30R9U meets all electrical and mechanical substitution criteria. Both parts share identical resistance value (30.9 Ohms), tolerance (±1%), power rating (1W), package (2512), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). Both are ROHS3 compliant with MSL 1 rating.

Q: What does "Not For New Designs" mean for the ERJ-1TNF30R9U?

A: This designation indicates that Panasonic is not recommending the ERJ-1TNF30R9U for incorporation into new product designs. The part remains available and functional for replacement applications, repair, and legacy systems. For new designs, the RC6432F30R9CS (active status) is the preferred choice.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist. The ERJ-1TNF30R9U is slightly larger (0.252" L vs. 0.248" L) and taller (0.028" max height vs. 0.026" max height). These differences fall within standard PCB design tolerances for 2512 package footprints and do not affect functional compatibility.

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

A: Yes. Both the RC6432F30R9CS and ERJ-1TNF30R9U carry MSL 1 (Unlimited) rating, indicating unlimited shelf life under normal storage conditions without special moisture control requirements.

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

A: The RC6432F30R9CS packaging format is not specified in the available data. The ERJ-1TNF30R9U is supplied in Tape & Reel (TR) format. Packaging format does not affect electrical or mechanical compatibility.

Q: Are both parts compliant with RoHS regulations?

A: Yes. Both the RC6432F30R9CS and ERJ-1TNF30R9U are ROHS3 compliant, meeting current regulatory requirements for hazardous substance restrictions.

Q: Can the ERJ-1TNF30R9U be used in automotive applications?

A: The ERJ-1TNF30R9U carries AEC-Q200 automotive qualification, making it suitable for automotive applications. The RC6432F30R9CS does not specify automotive qualification. If automotive compliance is required, the ERJ-1TNF30R9U provides additional qualification assurance.
