Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F56R2CS is determined by strict equivalence across the following critical parameters:

Electrical Equivalence: Resistance value of 56.2 Ohms, tolerance of ±1%, power rating of 1W, and temperature coefficient of ±100ppm/°C must be identical.

Mechanical Compatibility: Package designation of 2512 (6432 Metric) with two terminations ensures physical and electrical interface compatibility.

Environmental Compliance: Operating temperature range of -55°C to 155°C, Moisture Sensitivity Level 1, ROHS3 compliance, and REACH unaffected status must be maintained.

Composition: Thick film construction is required for thermal and electrical performance consistency.

Three substitute parts meet these criteria: CRCW251256R2FKEG (Vishay Dale), ERJ-1TNF56R2U (Panasonic Electronic Components), and RMCF2512FT56R2 (Stackpole Electronics Inc).

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: RMCF2512FT56R2 (Stackpole Electronics Inc) is recommended for new designs. This part maintains active product status, carries AEC-Q200 automotive qualification, and provides 4,702 units in current inventory. Stackpole's RMCF series offers established supply chain stability.

Secondary Selection: CRCW251256R2FKEG (Vishay Dale) is suitable for applications requiring extended inventory availability. This substitute maintains active status with 8,428 units in stock and AEC-Q200 certification. The CRCW2512 base product number indicates mature product maturity.

Legacy Applications: ERJ-1TNF56R2U (Panasonic Electronic Components) carries "Not For New Designs" status and should be used only in existing production lines or legacy system maintenance. While 4,609 units are available and AEC-Q200 certified, this part is not recommended for new circuit designs.

Original Part: RC6432F56R2CS remains suitable for continued use where Samsung Electro-Mechanics qualification is specified. The moisture-resistant feature and active status support ongoing applications.

Frequently Asked Questions (FAQ)

Q: Can CRCW251256R2FKEG replace RC6432F56R2CS in existing designs?

A: Yes. Both parts share identical electrical specifications (56.2 Ohms ±1%, 1W), operate across -55°C to 155°C, use thick film construction, and are packaged in 2512 (6432 Metric). Mechanical dimensions are equivalent within tolerance. Both are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between the Samsung and Stackpole versions?

A: The RC6432F56R2CS features moisture resistance as a primary characteristic. The RMCF2512FT56R2 carries AEC-Q200 automotive qualification. Both maintain identical electrical parameters, operating temperature range, and package specifications. Selection depends on application requirements and supply availability.

Q: Why is ERJ-1TNF56R2U marked "Not For New Designs"?

A: This designation indicates Panasonic has transitioned this product line. While the part remains electrically and mechanically equivalent and is currently in inventory, it should not be selected for new circuit designs. Use this part only for sustaining production of existing designs.

Q: Are there dimensional differences between these substitutes?

A: Minor dimensional variations exist within acceptable tolerances. RC6432F56R2CS and RMCF2512FT56R2 share identical length (0.248") and width (0.126"). CRCW251256R2FKEG measures 0.248" L x 0.124" W. ERJ-1TNF56R2U measures 0.252" L x 0.126" W. All variations remain within 2512 package specification and do not affect PCB layout or assembly.

Q: Do all substitutes support automotive applications?

A: CRCW251256R2FKEG, ERJ-1TNF56R2U, and RMCF2512FT56R2 carry AEC-Q200 automotive qualification. RC6432F56R2CS is specified as moisture resistant. Selection between automotive-qualified and moisture-resistant versions depends on application requirements.

Q: What packaging formats are available?

A: RC6432F56R2CS is supplied in standard packaging. CRCW251256R2FKEG, ERJ-1TNF56R2U, and RMCF2512FT56R2 are available in Tape & Reel (TR) format, suitable for automated assembly processes.
