Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC6432J754CS is determined by strict adherence to the following parameters:

Critical Parameters (Must Match Exactly):

• Resistance value: 750 kOhms
• Power rating: 1W
• Package / Case: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS3 Compliance

Allowable Variation:

• Tolerance: The RC6432J754CS specifies ±5%. Substitute parts with ±1% tolerance are acceptable as they represent tighter tolerance specifications and maintain backward compatibility.

Dimensional Tolerance:

• Physical dimensions (length, width, height) may vary within standard manufacturing tolerances for the 2512 package while maintaining electrical and mechanical compatibility.

All substitute parts listed maintain identical electrical performance characteristics and package footprint compatibility with the original part.

Parameter Comparison

Engineering Selection Recommendations

For Active Production and New Designs:

AC2512FK-07750KL (YAGEO) and CRCW2512750KFKEG (Vishay Dale) are the primary substitute options. Both parts are classified as Active with current product status, maintain full RoHS3 compliance, and provide tighter tolerance specifications (±1%) compared to the original RC6432J754CS (±5%). Both parts carry AEC-Q200 automotive qualification, which extends application scope beyond the original part specification.

For Automotive Applications:

AC2512FK-07750KL and CRCW2512750KFKEG are qualified to AEC-Q200 standards. These parts are suitable for automotive-grade circuit designs where component reliability and qualification documentation are required.

For Legacy or Existing Designs:

ERJ-1TNF7503U (Panasonic Electronic Components) is available as a substitute but carries a "Not For New Designs" product status classification. This part maintains full electrical and mechanical compatibility but should not be selected for new product development. Use this part only when replacing components in existing production runs or legacy systems.

Inventory Considerations:

CRCW2512750KFKEG maintains the highest inventory availability (313,100 pieces), followed by AC2512FK-07750KL (4,517 pieces) and ERJ-1TNF7503U (13,229 pieces).

Frequently Asked Questions (FAQ)

Q: Can AC2512FK-07750KL replace RC6432J754CS directly?

A: Yes. AC2512FK-07750KL is a direct substitute. Both parts share identical resistance value (750 kOhms), power rating (1W), package (2512), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and MSL rating (1). The AC2512FK-07750KL provides tighter tolerance (±1% versus ±5%) and AEC-Q200 automotive qualification, making it suitable for all applications where the original part is used.

Q: What is the difference between ±5% and ±1% tolerance?

A: Tolerance specifies the allowable deviation from the nominal resistance value. RC6432J754CS at ±5% tolerance can vary between 712.5 kOhms and 787.5 kOhms. Substitute parts with ±1% tolerance vary between 742.5 kOhms and 757.5 kOhms. Tighter tolerance provides more precise resistance values and is acceptable as a substitute for ±5% applications.

Q: Are all substitute parts in the 2512 package physically identical?

A: All substitute parts use the 2512 (6432 Metric) package and are mechanically compatible. Minor dimensional variations exist within standard manufacturing tolerances: length ranges from 0.248" to 0.252", width from 0.122" to 0.126", and height from 0.026" to 0.028". These variations do not affect PCB footprint compatibility or circuit performance.

Q: Why is ERJ-1TNF7503U marked "Not For New Designs"?

A: ERJ-1TNF7503U carries a "Not For New Designs" product status, indicating that Panasonic Electronic Components has discontinued active development and promotion of this part. While the part remains electrically and mechanically compatible, it should be used only for replacement in existing production or legacy systems. For new product development, select AC2512FK-07750KL or CRCW2512750KFKEG.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. All substitute parts listed (AC2512FK-07750KL, CRCW2512750KFKEG, and ERJ-1TNF7503U) are RoHS3 compliant and maintain MSL 1 (Unlimited) moisture sensitivity rating, matching the original RC6432J754CS specification.

Q: Which substitute part should I select for automotive applications?

A: Both AC2512FK-07750KL and CRCW2512750KFKEG carry AEC-Q200 automotive qualification. The original RC6432J754CS does not specify AEC-Q200 rating. For automotive-grade designs, either substitute part is appropriate. CRCW2512750KFKEG offers superior inventory availability.
