Key Parameters

Substitute Part Grouping Explanation

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

• Resistance Value: 33 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Package / Case: 0805 (2012 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Substitute parts are grouped into two categories based on power rating:

Category A - Direct Equivalents (0.125W / 1/8W): AC0805FR-0733KL, RC0805FR-0733KL, ERJ-6ENF3302V, RMCF0805FT33K0

Category B - Higher Power Rating (0.5W / 1/2W): CRCW080533K0FKEAHP, ERJ-UP6F3302V, RCS080533K0FKEA

Parts in Category B provide increased power dissipation capability while maintaining all other electrical and mechanical specifications. These are suitable for applications requiring higher thermal margin or pulse withstanding capability.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (0.125W Category)

AC0805FR-0733KL, RC0805FR-0733KL, ERJ-6ENF3302V, and RMCF0805FT33K0 are electrically and mechanically equivalent to AF0805FR-0733KL. All maintain identical resistance, tolerance, power rating, temperature coefficient, and operating temperature range. All substitute parts carry AEC-Q200 automotive qualification and ROHS3 compliance. Selection among these options is based on packaging preference (Tape & Reel versus Cut Tape & Digi-Reel) and manufacturer availability.

For Enhanced Thermal Performance (0.5W Category)

CRCW080533K0FKEAHP, ERJ-UP6F3302V, and RCS080533K0FKEA provide 0.5W power rating while maintaining all other electrical specifications. These parts are suitable for applications requiring increased power dissipation margin, pulse withstanding capability, or thermal headroom. All three carry AEC-Q200 qualification and ROHS3 compliance. Physical dimensions remain within 0805 package constraints with minor height variations.

Compliance Considerations

All substitute parts maintain ROHS3 compliance, AEC-Q200 automotive qualification (where specified), and Moisture Sensitivity Level 1 (Unlimited). No additional qualification or compliance testing is required for substitution within the specified categories.

Frequently Asked Questions (FAQ)

Q: Can I substitute a 0.5W part for the original 0.125W AF0805FR-0733KL?

A: Yes. CRCW080533K0FKEAHP, ERJ-UP6F3302V, and RCS080533K0FKEA are direct substitutes with identical electrical specifications and higher power rating. The 0.5W rating provides additional thermal margin and is backward compatible with 0.125W applications. Physical dimensions remain within 0805 package specifications.

Q: Are all substitute parts AEC-Q200 qualified?

A: All listed substitute parts carry AEC-Q200 automotive qualification. This ensures compliance with automotive reliability standards equivalent to the original part.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging?

A: Tape & Reel packaging is supplied on continuous tape for automated assembly. Cut Tape & Digi-Reel is supplied in smaller quantities on cut tape segments. Both are suitable for pick-and-place assembly. Selection depends on production volume and inventory management requirements.

Q: Do substitute parts have the same height specifications?

A: Substitute parts have minor height variations within the 0805 package specification. Heights range from 0.020" (0.50mm) to 0.028" (0.70mm). For applications with strict height constraints, verify the specific part height against PCB clearance requirements.

Q: Is the anti-sulfur feature available in all substitutes?

A: Anti-sulfur coating is specified for AF0805FR-0733KL and ERJ-UP6F3302V. Other substitutes do not explicitly list this feature. For applications requiring anti-sulfur protection, select AF0805FR-0733KL, ERJ-UP6F3302V, or verify coating specifications with the manufacturer.

Q: Can I mix different manufacturers in the same design?

A: Yes. All substitute parts meet identical electrical and mechanical specifications, AEC-Q200 qualification, and ROHS3 compliance. Cross-manufacturer substitution is supported for supply chain flexibility.
