Substitute Part Grouping Explanation

Substitution of the RG1005P-243-C-T10 is determined by strict equivalence in the following parameters: resistance value (24 kOhms), power rating (0.063W / 1/16W), package type (0402 / 1005 Metric), composition (thin film), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, REACH Unaffected, EAR99).

Tolerance specifications may be tightened from ±0.25% to ±0.1% or ±0.05% without functional degradation, as these represent improved accuracy. Temperature coefficient values may vary (±10ppm/°C or ±25ppm/°C) within the specified operating range. Packaging format (Tape & Reel versus Cut Tape) does not affect electrical performance. Automotive AEC-Q200 qualification is present in certain substitutes but not required for direct electrical equivalence.

Substitute parts are categorized as follows:

Upgrade substitutes (Susumu RG series): Active status parts with improved tolerance specifications or alternative packaging formats while maintaining identical electrical characteristics and anti-sulfur coating.

Direct equivalent (YAGEO RT series): Active status part with matching tolerance and electrical specifications, differing only in manufacturer and minor physical dimensions.

Cross-manufacturer upgrades: Active status parts from TE Connectivity, Panasonic, Vishay, and YAGEO offering improved tolerance, enhanced availability, or automotive qualification while maintaining core electrical parameters.

Engineering Selection Recommendations

For direct replacement with identical specifications: RT0402CRD0724KL (YAGEO) provides exact electrical equivalence with ±0.25% tolerance and ±25ppm/°C temperature coefficient. This part is active status and maintains the full -55°C to 155°C operating range. Selection is appropriate when component-level substitution is required without design modification.

For improved tolerance with maintained temperature coefficient: RG1005P-243-B-T5 (Susumu) upgrades tolerance to ±0.1% while preserving the ±25ppm/°C temperature coefficient and full automotive AEC-Q200 qualification. This part offers enhanced accuracy with identical thermal performance and is available in high quantity (12,183 pcs).

For enhanced accuracy and reduced thermal drift: RG1005N-243-B-T5 (Susumu) provides ±0.1% tolerance with improved ±10ppm/°C temperature coefficient, reducing thermal drift by 60% compared to the original specification. This part maintains AEC-Q200 qualification and full operating temperature range.

For maximum accuracy specification: RG1005N-243-W-T1 (Susumu) delivers ±0.05% tolerance with ±10ppm/°C temperature coefficient, representing the tightest tolerance available in this resistance value and package. This part is suitable for precision analog circuits requiring minimal tolerance stack-up.

Frequently Asked Questions (FAQ)

Q: Can RG1005P-243-C-T10 be replaced with a part having tighter tolerance?

A: Yes. Parts with ±0.1% or ±0.05% tolerance are direct substitutes, as tighter tolerance represents improved accuracy without affecting circuit compatibility. The original ±0.25% specification is maintained or exceeded by all recommended substitutes.

Q: What is the significance of temperature coefficient differences between ±10ppm/°C and ±25ppm/°C?

A: Temperature coefficient defines resistance change per degree Celsius. At 100°C temperature swing, a ±25ppm/°C part exhibits 2.5% maximum resistance change, while a ±10ppm/°C part exhibits 1% maximum change. Selection depends on circuit sensitivity to resistance variation across the operating temperature range.

Q: Are Susumu RG1005N series parts compatible with RG1005P series in the same circuit?

A: Yes. Both series use identical 0402 package, resistance value, power rating, and operating temperature range. The RG1005N series offers improved temperature coefficient (±10ppm/°C versus ±25ppm/°C). Physical dimensions and electrical performance are compatible.

Q: Does packaging format (Tape & Reel versus Cut Tape) affect electrical performance?

A: No. Packaging format affects only handling and assembly logistics. Electrical specifications, performance, and reliability are identical regardless of packaging format. Selection should be based on assembly equipment compatibility.

Q: Is AEC-Q200 qualification required for non-automotive applications?

A: No. AEC-Q200 qualification is a reliability and quality standard specific to automotive use. Non-automotive applications may use parts without this certification. However, AEC-Q200 qualified parts are acceptable substitutes in any application.

Q: Can RT0402CRD0724KL (YAGEO) replace RG1005P-243-C-T10 in automotive circuits?

A: RT0402CRD0724KL provides electrical equivalence but lacks AEC-Q200 qualification. For automotive applications requiring AEC-Q200 compliance, use RG1005P-243-B-T5, RG1005N-243-B-T5, or ERA-2AEB243X instead.

Q: What is the maximum operating temperature difference between substitute options?

A: MCS04020D2402BE100 operates to 125°C maximum, while all other substitutes operate to 155°C. This 30°C difference is significant only in high-temperature applications. Verify circuit requirements before selecting MCS04020D2402BE100.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, matching the environmental compliance of the original RG1005P-243-C-T10.
