Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC6432F3240CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 324 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
• Termination count: 2
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

All identified substitute parts meet these mandatory parameters. Substitute parts are further categorized by product status and additional certifications. The AC2512FK-07324RL (YAGEO) is classified as an upgrade substitute due to Active product status and automotive AEC-Q200 qualification. The ERJ-1TNF3240U (Panasonic) and RMCF2512FT324R (Stackpole) are classified as similar substitutes; the Panasonic part carries a "Not For New Designs" status while the Stackpole part maintains Active status with AEC-Q200 certification.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Upgrade Substitute): The AC2512FK-07324RL (YAGEO) is the recommended upgrade substitute. This part maintains Active product status, carries AEC-Q200 automotive qualification, and provides equivalent electrical and mechanical performance to the RC6432F3240CS. The AC2512FK-07324RL is suitable for new designs and applications requiring automotive-grade reliability.

Secondary Selection (Active Status): The RMCF2512FT324R (Stackpole Electronics Inc) is an alternative substitute with Active product status and AEC-Q200 certification. This part is electrically and mechanically equivalent to the RC6432F3240CS and is suitable for applications requiring automotive-qualified components.

Legacy Applications Only: The ERJ-1TNF3240U (Panasonic) carries a "Not For New Designs" product status classification. This part is electrically and mechanically equivalent but is designated for legacy or existing design support only. Use of this part in new designs is not recommended.

All three substitute parts are RoHS3 compliant, carry MSL 1 (Unlimited) ratings, and operate across the identical temperature range of -55°C to 155°C.

Frequently Asked Questions (FAQ)

Q: Can the AC2512FK-07324RL directly replace the RC6432F3240CS? A: Yes. The AC2512FK-07324RL meets all mandatory electrical and mechanical parameters: 324 Ohm resistance, ±1% tolerance, 1W power rating, 2512 package, thick film composition, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. Dimensional variations are within acceptable PCB assembly tolerances for the 2512 package class.

Q: What is the difference between the three substitute parts? A: All three substitutes are electrically equivalent. The primary differences are manufacturer identity, product status, and packaging format. The AC2512FK-07324RL and RMCF2512FT324R maintain Active status; the ERJ-1TNF3240U is designated "Not For New Designs." All three carry AEC-Q200 automotive certification except the original RC6432F3240CS.

Q: Are there dimensional compatibility concerns when substituting? A: Dimensional variations exist within the 2512 package specification. Length ranges from 0.248" to 0.252" (6.30mm to 6.40mm), width from 0.122" to 0.126" (3.10mm to 3.20mm), and height from 0.026" to 0.028" (0.65mm to 0.70mm). These variations are within standard PCB design tolerances for 2512 components and do not affect functional compatibility.

Q: Which substitute should be used for new product designs? A: The AC2512FK-07324RL (YAGEO) or RMCF2512FT324R (Stackpole) are appropriate for new designs. Both maintain Active product status. The ERJ-1TNF3240U is not recommended for new designs due to its "Not For New Designs" classification.

Q: Do all substitutes have identical moisture sensitivity ratings? A: Yes. All parts, including the original RC6432F3240CS, carry MSL 1 (Unlimited) ratings, indicating unlimited shelf life under standard storage conditions without moisture bake requirements.

Q: Are all substitutes RoHS3 compliant? A: Yes. The RC6432F3240CS and all three substitute parts are RoHS3 compliant and REACH unaffected.
