Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment of the following parameters:

Mandatory Matching Parameters:

• Resistance value: 300 Ohms
• Tolerance: ±1%
• Power rating: 1W
• Package / Case: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Acceptable Variation Parameters:

• Manufacturer identity (different suppliers)
• Packaging format (Tape & Reel or Cut Tape)
• Physical dimensions within 2512 package tolerance
• Height variation within standard 2512 specifications
• Series designation (RC, RC_L, AC, CRCW, ERJ-1TN, RMCF)

Upgrade Consideration:

• AC2512FK-07300RL includes Automotive AEC-Q200 certification, providing enhanced qualification for automotive applications while maintaining all base electrical and mechanical specifications.

Legacy Status Consideration:

• ERJ-1TNF3000U is marked "Not For New Designs" but remains electrically and mechanically compatible for replacement in existing applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status): RC2512FK-07300RL, CRCW2512300RFKEG, and RMCF2512FT300R are direct electrical and mechanical equivalents with Active product status. Selection among these three is based on packaging availability (Tape & Reel or Cut Tape) and supply chain requirements.

Upgraded Substitute (Automotive Applications): AC2512FK-07300RL is recommended for applications requiring Automotive AEC-Q200 qualification. This part maintains all electrical and mechanical specifications of the base RC6432F301CS while adding automotive-grade certification.

Legacy Substitute (Replacement Only): ERJ-1TNF3000U is electrically and mechanically compatible but carries "Not For New Designs" status. This part is suitable only for replacement in existing applications where the original part is unavailable.

Compliance Verification: All listed substitutes maintain ROHS3 compliance, MSL Level 1 (Unlimited), and REACH Unaffected status, ensuring regulatory alignment with the original RC6432F301CS.

Frequently Asked Questions (FAQ)

Q: Can RC2512FK-07300RL replace RC6432F301CS directly on the PCB? A: Yes. Both parts share identical electrical specifications (300 Ω ±1%, 1W), temperature coefficient (±100ppm/°C), operating range (-55°C to 155°C), and 2512 package footprint. Physical dimensions are within acceptable tolerance for the 2512 package class.

Q: What is the difference between Tape & Reel and Cut Tape packaging? A: Tape & Reel packaging is supplied on continuous carrier tape suitable for automated pick-and-place assembly. Cut Tape packaging is supplied in shorter tape segments for manual or lower-volume assembly. Both formats contain identical components; the difference is in supply format only.

Q: Why is AC2512FK-07300RL listed as an upgrade? A: AC2512FK-07300RL includes Automotive AEC-Q200 certification, indicating qualification for automotive-grade applications. All other electrical and mechanical parameters remain identical to RC6432F301CS. Use this part when automotive reliability standards are required.

Q: Can ERJ-1TNF3000U be used in new designs? A: No. ERJ-1TNF3000U is marked "Not For New Designs" by the manufacturer. This part is suitable only for replacement in existing applications or legacy product support. For new designs, select from RC2512FK-07300RL, AC2512FK-07300RL, CRCW2512300RFKEG, or RMCF2512FT300R.

Q: Are there dimensional differences between substitute parts? A: All parts conform to the 2512 (6432 Metric) package specification. Minor dimensional variations exist within standard tolerance (length 0.248–0.252", width 0.122–0.126", height 0.026–0.028"). These variations are within PCB footprint tolerance and do not affect interchangeability.

Q: Do all substitutes have the same moisture sensitivity level? A: Yes. All listed substitutes have MSL Level 1 (Unlimited), matching RC6432F301CS. This indicates no moisture sensitivity restrictions for storage or handling.

Q: Which substitute has the highest inventory availability? A: RMCF2512FT300R has 28,723 pieces in stock, followed by ERJ-1TNF3000U with 21,058 pieces. CRCW2512300RFKEG has 8,141 pieces. RC2512FK-07300RL has 5,200 pieces. Inventory levels should be verified with your supplier for current availability.
