Key Parameters

Substitute Part Grouping Explanation

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

Mandatory Equivalence Criteria:

• Resistance value: 21 Ohms
• Tolerance: ±1%
• Package / Case: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Status: ROHS3 Compliant

Allowable Variations:

• Power Rating: 1W or higher (1.5W acceptable as upgrade)
• Packaging format: Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel®
• Manufacturer: Different qualified suppliers
• Product Status: Active or Not For New Designs (with notation)
• Additional features: Automotive AEC-Q200 qualification (upgrade feature)

Substitute parts are grouped by functional equivalence level: Direct equivalents maintain identical electrical and mechanical specifications; Upgrade equivalents add automotive qualification or higher power rating; Similar equivalents maintain core specifications with minor dimensional tolerance variations.

Parameter Comparison

Engineering Selection Recommendations

RC2512FK-0721RL (YAGEO) - Direct Equivalent

This part maintains identical electrical specifications and mechanical compatibility with the RC6432F21R0CS. Both components are Active status with ROHS3 compliance and unlimited moisture sensitivity rating. Selection is appropriate for general industrial applications requiring standard thick film resistor performance.

AC2512FK-0721RL (YAGEO) - Upgrade Equivalent

This part adds Automotive AEC-Q200 qualification while maintaining all core electrical and mechanical specifications. Power rating remains 1W. Selection is appropriate when automotive-grade reliability is required or when design standards mandate AEC-Q200 compliance. Active product status ensures long-term availability.

CRCW251221R0FKEGHP (Vishay Dale) - Upgrade Equivalent

This part provides increased power rating (1.5W) with Automotive AEC-Q200 qualification and pulse withstanding capability. All electrical specifications remain equivalent. Dimensional variations are within 2512 package tolerance. Selection is appropriate for applications requiring higher power dissipation margin or automotive qualification. Active product status ensures supply continuity.

ERJ-1TNF21R0U (Panasonic Electronic Components) - Similar Equivalent

This part maintains all core electrical specifications with Automotive AEC-Q200 qualification. Product status is Not For New Designs, indicating this component is in mature phase with limited future availability. Selection is appropriate only for existing design maintenance or when existing inventory must be maintained. New designs should transition to Active status alternatives.

Frequently Asked Questions (FAQ)

Q: Can RC2512FK-0721RL replace RC6432F21R0CS in existing designs?

A: Yes. RC2512FK-0721RL is a direct equivalent with identical resistance (21 Ohms), tolerance (±1%), power rating (1W), package (2512), and operating temperature range (-55°C ~ 155°C). Both components are ROHS3 compliant with MSL 1 rating. Packaging format differs (Tape & Reel vs. Bulk), but electrical and mechanical compatibility is complete.

Q: What is the difference between AC2512FK-0721RL and RC2512FK-0721RL?

A: Both parts are manufactured by YAGEO with identical electrical specifications (21 Ohms, ±1%, 1W, 2512 package). AC2512FK-0721RL adds Automotive AEC-Q200 qualification, making it suitable for automotive applications. RC2512FK-0721RL is standard industrial grade. Selection depends on application requirements and compliance mandates.

Q: Why does CRCW251221R0FKEGHP have 1.5W rating instead of 1W?

A: CRCW251221R0FKEGHP is an upgrade equivalent with higher power rating (1.5W) while maintaining the same 21 Ohm resistance and ±1% tolerance. The increased power rating provides additional thermal margin and is backward compatible with 1W applications. This component also includes pulse withstanding capability and Automotive AEC-Q200 qualification.

Q: Is ERJ-1TNF21R0U suitable for new product designs?

A: ERJ-1TNF21R0U is classified as Not For New Designs. While electrically and mechanically equivalent with Automotive AEC-Q200 qualification, this product status indicates limited future availability. New designs should use Active status alternatives: RC2512FK-0721RL, AC2512FK-0721RL, or CRCW251221R0FKEGHP.

Q: Are dimensional variations between substitute parts significant?

A: Dimensional variations are within 2512 package tolerance specifications. 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 do not affect PCB footprint compatibility or electrical performance. All parts are qualified for 2512 package placement.

Q: What packaging formats are available for these substitutes?

A: RC6432F21R0CS is supplied in Bulk format. Substitute parts are available in Tape & Reel (TR) format (YAGEO and Vishay Dale) or Cut Tape (CT) & Digi-Reel® format (Panasonic). Packaging format selection depends on assembly process requirements and volume. Electrical and mechanical specifications remain identical across all packaging formats.

Q: Do all substitute parts meet ROHS3 compliance?

A: Yes. All listed substitute parts (RC2512FK-0721RL, AC2512FK-0721RL, CRCW251221R0FKEGHP, ERJ-1TNF21R0U) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. REACH status is Unaffected for all parts. Compliance documentation is consistent across all alternatives.
