Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMCS0805FT23K7 is determined by strict equivalence across the following critical parameters:

• Resistance value: 23.7 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Termination count: 2
• Moisture sensitivity level: 1 (Unlimited)

All identified substitute parts meet these core electrical and mechanical specifications. Variations in secondary characteristics such as manufacturer features (automotive AEC-Q200 qualification, anti-sulfur construction, moisture resistance), packaging format (Tape & Reel vs. Cut Tape), physical height, and regulatory compliance status are noted but do not disqualify substitution eligibility when core parameters align.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain electrical and mechanical equivalence to the RMCS0805FT23K7 across core specifications. Selection among substitutes should be based on the following criteria:

RoHS Compliance: CRCW080523K7FKTA is RoHS non-compliant and REACH affected. For applications requiring RoHS3 compliance, select from RMCF0805FT23K7, CRCW080523K7FKEA, ERJ-6ENF2372V, or RC0805FR-0723K7L.

Automotive Applications: RMCF0805FT23K7, CRCW080523K7FKEA, CRCW080523K7FKTA, and ERJ-6ENF2372V carry AEC-Q200 automotive qualification. The original RMCS0805FT23K7 and RC0805FR-0723K7L do not carry this rating.

Physical Height Constraints: Component height varies from 0.020" (0.50mm) to 0.028" (0.70mm). CRCW080523K7FKEA and CRCW080523K7FKTA offer the lowest profile at 0.020" maximum seated height.

Packaging Format: RMCS0805FT23K7, RMCF0805FT23K7, CRCW080523K7FKEA, CRCW080523K7FKTA, and ERJ-6ENF2372V are supplied in Tape & Reel format. RC0805FR-0723K7L is supplied in Cut Tape & Digi-Reel format.

Inventory Availability: ERJ-6ENF2372V (97,932 units), RC0805FR-0723K7L (76,019 units), and CRCW080523K7FKEA (37,192 units) offer higher stock levels compared to the original part.

Frequently Asked Questions (FAQ)

Q: Can RMCF0805FT23K7 replace RMCS0805FT23K7 in non-automotive applications?

A: Yes. Both parts share identical electrical specifications (23.7 kΩ, ±1%, 0.125W, ±100ppm/°C, -55°C ~ 155°C). The RMCF variant includes automotive AEC-Q200 qualification, which does not restrict use in general applications. Physical height difference (0.026" vs. 0.024") must be verified against PCB layout constraints.

Q: Is CRCW080523K7FKTA suitable for new designs?

A: CRCW080523K7FKTA is electrically equivalent but is RoHS non-compliant and REACH affected. Use is restricted to applications where RoHS compliance is not required. For new designs, CRCW080523K7FKEA (RoHS3 compliant variant) is preferred.

Q: What is the difference between anti-sulfur and moisture-resistant features?

A: Anti-sulfur construction (RMCS0805FT23K7) protects against sulfur-containing atmospheric corrosion. Moisture-resistant construction (RC0805FR-0723K7L) provides protection against moisture ingress. Both are distinct protective mechanisms. Selection depends on environmental exposure conditions.

Q: Can I use ERJ-6ENF2372V in space-constrained PCB layouts?

A: ERJ-6ENF2372V has a maximum seated height of 0.028" (0.70mm), which is the highest among listed substitutes. For height-critical applications, CRCW080523K7FKEA or CRCW080523K7FKTA (0.020" maximum) are preferred.

Q: Are all substitute parts available in the same packaging quantity?

A: No. Packaging format differs: RMCS0805FT23K7, RMCF0805FT23K7, CRCW080523K7FKEA, CRCW080523K7FKTA, and ERJ-6ENF2372V are supplied in Tape & Reel. RC0805FR-0723K7L is supplied in Cut Tape & Digi-Reel format. Verify packaging requirements with procurement specifications.

Q: Which substitute offers the best long-term availability?

A: All listed parts are active in production. RMCF0805FT23K7 (Stackpole, same manufacturer as original) and ERJ-6ENF2372V (Panasonic, 97,932 units in stock) represent established supply sources with high inventory levels.
