Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F2492CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 24.9 kOhms
• Tolerance: ±1%
• Package / Case: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• Number of Terminations: 2

Allowable Variation Parameters:

• Power Rating: 0.063W (1/16W) or higher
• Manufacturer: Different manufacturers permitted
• Packaging format: Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel®
• Additional features: Automotive AEC-Q200 certification, Anti-Sulfur treatment, or Moisture Resistant construction are acceptable enhancements

Substitute parts are classified into three categories: Direct equivalents (identical specifications), upgrades (higher power rating with same package), and similar parts (enhanced features with equivalent base specifications).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Preferred for Drop-In Replacement):

CR0402-FX-2492GLF (Bourns Inc.) and RMCF0402FT24K9 (Stackpole Electronics Inc) are direct functional equivalents to RC1005F2492CS. Both maintain identical electrical specifications, package dimensions, and ROHS3 compliance. CR0402-FX-2492GLF is available in Tape & Reel packaging matching the original specification. RMCF0402FT24K9 offers higher inventory availability (713,151 pcs) with Automotive AEC-Q200 certification, providing enhanced reliability for applications requiring automotive-grade components.

Active Status Alternatives:

RC0402FR-0724K9L (YAGEO) is an Active product with moisture-resistant construction identical to the main part. This component is available in high volume (532,306 pcs) and provides supply chain continuity. AC0402FR-0724K9L and AF0402FR-0724K9L (both YAGEO) are Active alternatives with Automotive AEC-Q200 certification and additional environmental protection features (moisture resistant and anti-sulfur treatment respectively).

Upgrade Option:

ERJ-2RKF2492X (Panasonic Electronic Components) is classified as an upgrade substitute with increased power rating of 0.1W (1/10W) versus the original 0.063W. This component maintains all other specifications and adds Automotive AEC-Q200 certification. The higher power rating provides thermal margin in applications with elevated ambient temperatures or higher current density conditions.

Discontinued Component:

MCR01MRTF2492 (Rohm Semiconductor) is marked as Discontinued at DiGi Electronics and should not be selected for new designs or long-term production requirements.

Non-Compliant Component:

CRCW040224K9FKTD (Vishay Dale) is RoHS non-compliant and REACH Affected. This component is not suitable for applications requiring regulatory compliance and should be avoided in favor of ROHS3 compliant alternatives.

Frequently Asked Questions (FAQ)

Q: Can I substitute RC1005F2492CS with a part having higher power rating?

A: Yes. ERJ-2RKF2492X with 0.1W (1/10W) power rating is a valid upgrade substitute. The higher power rating is backward compatible and provides additional thermal headroom. All other electrical and mechanical parameters remain equivalent.

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

A: Both packaging formats contain identical components with different delivery methods. Tape & Reel (TR) is supplied on continuous tape suitable for automated pick-and-place equipment. Cut Tape (CT) & Digi-Reel® is supplied in shorter tape segments. Selection depends on assembly equipment capability and volume requirements.

Q: Are Automotive AEC-Q200 certified parts interchangeable with standard industrial parts?

A: Yes. Automotive AEC-Q200 certified parts (CRCW040224K9FKED, RMCF0402FT24K9, AC0402FR-0724K9L, AF0402FR-0724K9L) meet or exceed industrial specifications and are fully interchangeable with non-automotive rated equivalents. These parts are suitable for both automotive and industrial applications.

Q: Why should I avoid CRCW040224K9FKTD?

A: CRCW040224K9FKTD is RoHS non-compliant and REACH Affected, making it unsuitable for applications requiring regulatory compliance with environmental directives. ROHS3 compliant alternatives are available with identical specifications.

Q: What does Moisture Sensitivity Level 1 mean?

A: MSL 1 indicates Unlimited shelf life without moisture baking requirements. Components with MSL 1 can be stored and handled under standard conditions without special humidity control or pre-reflow baking procedures.

Q: Is the 0402 package dimension critical for substitution?

A: Yes. The 0402 (1005 Metric) package dimension of 0.039" L x 0.020" W (1.00mm x 0.50mm) is mandatory for PCB footprint compatibility. All substitute parts must maintain this exact package specification.

Q: Can I use RC0402FR-0724K9L as a direct replacement?

A: Yes. RC0402FR-0724K9L is an Active product with identical electrical specifications, moisture-resistant construction, and ROHS3 compliance. It is a direct functional equivalent suitable for drop-in replacement.
