Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005J911CS is determined by strict adherence to the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 910 Ohms (exact match required)
• Package / Case: 0402 (1005 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C to 155°C (exact match or wider range acceptable)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match or better acceptable)
• RoHS Status: ROHS3 Compliant (exact match required)

Allowable Variation Parameters:

• Tolerance: ±5% (baseline); ±1% tolerance represents an upgrade specification and is acceptable as a direct substitute
• Power Rating: 0.063W (baseline); higher power ratings (0.1W) represent upgrade specifications and are acceptable as substitutes
• Features: Moisture Resistant (baseline); additional features such as Automotive AEC-Q200 certification represent upgrade specifications

Substitute parts are categorized into three groups based on specification alignment:

Direct Substitutes: Parts matching all mandatory parameters with identical tolerance (±5%) and power rating (0.063W). These provide one-to-one replacement capability.

Upgrade Substitutes: Parts matching all mandatory parameters but offering improved tolerance (±1%) and/or higher power rating (0.1W). These provide enhanced performance characteristics while maintaining full compatibility.

Similar Substitutes: Parts matching all mandatory parameters with identical tolerance (±5%) and power rating (0.063W) but offering additional certifications such as Automotive AEC-Q200. These provide equivalent performance with enhanced qualification status.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution (Equivalent Replacement):

RC0402JR-07910RL (YAGEO) is the primary direct substitute for RC1005J911CS. This part maintains identical electrical specifications (910 Ohms ±5%, 0.063W), mechanical package (0402), and environmental ratings (MSL 1, ROHS3 Compliant). Both parts feature moisture-resistant thick film construction and operate across the same temperature range. YAGEO RC0402JR-07910RL is currently Active product status with 29,397 pieces in stock inventory, providing superior availability compared to the original Samsung part (988 pieces).

Upgrade Substitution (Enhanced Specifications):

RC0402FR-07910RL (YAGEO) provides improved tolerance specification (±1% versus ±5%) while maintaining identical power rating (0.063W), package format (0402), and moisture-resistant thick film composition. This part is Active product status with 219,114 pieces in inventory. The tighter tolerance specification enables use in applications requiring higher precision without any mechanical or thermal incompatibility.

ERJ-2RKF9100X (Panasonic Electronic Components) offers both improved tolerance (±1%) and higher power rating (0.1W versus 0.063W) in the same 0402 package. This part carries Automotive AEC-Q200 certification and is Active product status with 322,296 pieces in inventory. The increased power dissipation capability provides design margin for thermal stress conditions.

Similar Substitution (Equivalent with Enhanced Certification):

RMCF0402JT910R (Stackpole Electronics Inc) maintains identical electrical specifications (910 Ohms ±5%, 0.063W) and package format (0402) while adding Automotive AEC-Q200 qualification. This part is Active product status with 1,014 pieces in inventory. The automotive certification provides additional reliability assurance for applications requiring automotive-grade component qualification.

Parts to Avoid:

MCR01MRTF9100 (Rohm Semiconductor) is listed as Discontinued at DiGi Electronics and should not be selected for new designs or long-term production applications despite offering ±1% tolerance upgrade. Discontinued status indicates limited future availability and potential supply chain risk.

Frequently Asked Questions (FAQ)

Q: Can RC0402JR-07910RL directly replace RC1005J911CS without circuit modification?

A: Yes. RC0402JR-07910RL is a direct substitute with identical resistance (910 Ohms), tolerance (±5%), power rating (0.063W), package format (0402), and operating temperature range (-55°C to 155°C). Both parts are RoHS3 compliant with MSL 1 rating and thick film composition. No circuit modification is required.

Q: What is the difference between the ±5% tolerance parts and ±1% tolerance parts?

A: Tolerance specifies the allowable deviation from the nominal 910 Ohm resistance value. ±5% tolerance allows resistance values between 864.5 and 955.5 Ohms. ±1% tolerance allows resistance values between 900.9 and 919.1 Ohms. The ±1% tolerance parts (RC0402FR-07910RL, ERJ-2RKF9100X, MCR01MRTF9100) provide tighter resistance control suitable for precision applications. ±1% parts are fully compatible as substitutes for ±5% applications.

Q: Can I use ERJ-2RKF9100X (0.1W power rating) in place of RC1005J911CS (0.063W power rating)?

A: Yes. ERJ-2RKF9100X has a higher power dissipation capability (0.1W versus 0.063W) and is fully compatible. Higher power rating represents an upgrade specification that provides additional thermal margin. The 0402 package dimensions, operating temperature range, and all other mechanical and environmental parameters are identical.

Q: What does Automotive AEC-Q200 certification mean?

A: AEC-Q200 is an automotive industry qualification standard for passive components. Parts carrying this certification (ERJ-2RKF9100X, RMCF0402JT910R) have undergone additional reliability testing and qualification procedures required for automotive applications. These parts are suitable for both automotive and general-purpose applications.

Q: Why is MCR01MRTF9100 marked as "Discontinued at DiGi Electronics"?

A: Discontinued status indicates that the supplier (DiGi Electronics) no longer actively stocks or supports this part. While 881 pieces remain in current inventory, future availability cannot be assured. For new designs or production quantities, select from Active product status parts: RC0402JR-07910RL, RC0402FR-07910RL, ERJ-2RKF9100X, or RMCF0402JT910R.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (RC0402JR-07910RL, ERJ-2RKF9100X, MCR01MRTF9100, RC0402FR-07910RL, RMCF0402JT910R) are RoHS3 compliant, matching the original RC1005J911CS specification. All parts also maintain MSL 1 (Unlimited) moisture sensitivity level.

Q: Can I mix different substitute parts in the same circuit board assembly?

A: Yes. All substitute parts are electrically and mechanically compatible with each other and with the original RC1005J911CS. They share identical 0402 package dimensions, operating temperature range, and environmental ratings. Mixing parts from different manufacturers in the same assembly is acceptable from an engineering compatibility standpoint.

Q: What is the difference between "Tape & Reel (TR)" and "Cut Tape (CT) & Digi-Reel®" packaging?

A: Both packaging formats contain the same component. Tape & Reel (TR) is standard reel packaging for automated assembly equipment. Cut Tape (CT) & Digi-Reel® is a smaller quantity format suitable for manual assembly or prototyping. The electrical and mechanical specifications of the component are identical regardless of packaging format.
