Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AF0805FR-0723K2L are qualified based on the following criteria:

• Electrical Specifications: Resistance value of 23.2 kOhms, tolerance of ±1%, and power rating of 0.125W must be identical
• Package Compatibility: 0805 (2012 Metric) package with two terminations
• Environmental Specifications: Operating temperature range of -55°C to 155°C and temperature coefficient of ±100ppm/°C
• Regulatory Compliance: ROHS3 compliance and MSL 1 rating required
• Composition: Thick film construction

All identified substitutes meet these core parameters and are available from established manufacturers with active product status.

Parameter Comparison

Engineering Selection Recommendations

All four parts maintain identical core electrical and mechanical specifications. Selection among these substitutes should be based on:

Automotive Applications: The AF0805FR-0723K2L, CRCW080523K2FKEA, and ERJ-6ENF2322V all carry AEC-Q200 automotive qualification. The RC0805FR-0723K2L lacks this certification and is suitable for non-automotive applications.

Physical Constraints: The CRCW080523K2FKEA offers the lowest seated height at 0.020" (0.50mm), beneficial for space-constrained designs. The ERJ-6ENF2322V has the highest seated height at 0.028" (0.70mm). The AF0805FR-0723K2L and RC0805FR-0723K2L both measure 0.024" (0.60mm).

Feature Differentiation: The AF0805FR-0723K2L includes anti-sulfur coating. The RC0805FR-0723K2L emphasizes moisture resistance. Both CRCW080523K2FKEA and ERJ-6ENF2322V carry AEC-Q200 automotive qualification.

Availability: All parts are in active production with substantial inventory levels.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-0723K2L replace AF0805FR-0723K2L in automotive applications?

A: No. While both parts share identical electrical specifications and package dimensions, the RC0805FR-0723K2L lacks AEC-Q200 automotive qualification. For automotive applications, use CRCW080523K2FKEA or ERJ-6ENF2322V as substitutes.

Q: Are all substitute parts pin-compatible with the original AF0805FR-0723K2L?

A: Yes. All substitutes use the 0805 (2012 Metric) package with two terminations and identical footprint dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm).

Q: Does the difference in seated height affect PCB assembly?

A: Seated height differences (0.020" to 0.028") are within standard 0805 package tolerances and do not affect PCB assembly compatibility. However, in height-constrained applications, the CRCW080523K2FKEA at 0.020" maximum height offers the lowest profile.

Q: What is the significance of anti-sulfur coating in the AF0805FR-0723K2L?

A: Anti-sulfur coating protects the resistor from sulfur-containing environmental contaminants, extending reliability in harsh industrial and automotive environments. This feature is specific to the AF series and not present in the other substitutes.

Q: Are all parts ROHS3 compliant?

A: Yes. All four parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting current environmental and regulatory requirements.
