Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG1005N-1131-P-T1 is determined by the following critical parameters:

Primary Substitution Criteria:

• Resistance value: 1.13 kOhms (exact match required)
• Package type: 0402 (1005 Metric) (exact match required)
• Power rating: 0.063W minimum (1/16W)
• Operating temperature range: -55°C to 155°C minimum
• Composition: Thin film construction
• RoHS3 compliance

Secondary Compatibility Factors:

• Tolerance: ±0.02% preferred; ±0.1% acceptable for non-critical applications
• Temperature coefficient: ±10ppm/°C preferred; ±25ppm/°C acceptable depending on circuit requirements
• Automotive qualification: AEC-Q200 preferred for automotive applications
• Anti-sulfur coating: Preferred for harsh environments

Substitute parts are grouped into two categories: direct upgrades (identical electrical specifications with improved product status) and functional equivalents (compatible electrical performance with tolerance or temperature coefficient variations).

Engineering Selection Recommendations

RG1005V-1131-P-T1 (Recommended Primary Substitute)

The RG1005V-1131-P-T1 is the preferred substitute for the obsolete RG1005N-1131-P-T1. This part maintains identical electrical specifications (1.13 kOhms ±0.02% tolerance) and package configuration while offering superior temperature coefficient performance (±5ppm/°C versus ±10ppm/°C). Both components carry AEC-Q200 automotive qualification and anti-sulfur coating. The RG1005V-1131-P-T1 is currently in active production status with higher inventory availability (794 Pcs), ensuring long-term supply continuity. This substitute provides direct functional equivalence with enhanced performance characteristics and is suitable for all applications previously served by the RG1005N-1131-P-T1.

CPF0402B1K13E1 (Secondary Equivalent)

The CPF0402B1K13E1 from TE Connectivity Passive Product serves as a functional equivalent for applications where automotive qualification and anti-sulfur coating are not required. This part maintains the same resistance value (1.13 kOhms), power rating (0.063W), and package format (0402). The tolerance specification is ±0.1%, which is less stringent than the main part's ±0.02%. The temperature coefficient is ±25ppm/°C, representing a trade-off in temperature stability. The CPF0402B1K13E1 is ROHS3 compliant and currently in active production with substantial inventory (2747 Pcs). This substitute is appropriate for general-purpose applications where the relaxed tolerance and temperature coefficient specifications are acceptable.

Frequently Asked Questions (FAQ)

Q: Can the RG1005V-1131-P-T1 be used as a direct replacement for the RG1005N-1131-P-T1?

A: Yes. The RG1005V-1131-P-T1 is a direct substitute with identical resistance (1.13 kOhms), tolerance (±0.02%), power rating (0.063W), and package (0402). Both components feature AEC-Q200 automotive qualification and anti-sulfur coating. The RG1005V-1131-P-T1 offers improved temperature coefficient performance (±5ppm/°C) and is in active production status.

Q: What are the key differences between the RG1005V-1131-P-T1 and CPF0402B1K13E1?

A: The primary differences are tolerance specification (±0.02% versus ±0.1%), temperature coefficient (±5ppm/°C versus ±25ppm/°C), automotive qualification (AEC-Q200 present versus absent), and anti-sulfur coating (present versus absent). Both maintain identical resistance value, power rating, and package format. Selection depends on application requirements for precision and environmental conditions.

Q: Is the CPF0402B1K13E1 suitable for automotive applications?

A: The CPF0402B1K13E1 lacks AEC-Q200 automotive qualification and anti-sulfur coating. For automotive applications requiring these specifications, the RG1005V-1131-P-T1 is the appropriate choice. The CPF0402B1K13E1 is suitable for general-purpose and industrial applications where automotive qualification is not mandated.

Q: What is the significance of the ±0.02% tolerance specification?

A: The ±0.02% tolerance indicates a precision thin film resistor suitable for high-accuracy circuit applications. This tight tolerance ensures minimal resistance variation across the specified operating temperature range and production batches. Applications requiring this precision include precision instrumentation, measurement circuits, and reference networks.

Q: Are all three parts RoHS3 compliant?

A: Yes. The RG1005N-1131-P-T1, RG1005V-1131-P-T1, and CPF0402B1K13E1 are all ROHS3 compliant, meeting environmental and regulatory requirements for lead-free and restricted substance compliance.

Q: What does Moisture Sensitivity Level 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life and requires no special moisture control during storage, handling, or assembly. This classification applies to all three parts in this comparison.

Q: Can these parts be used interchangeably in existing designs?

A: The RG1005V-1131-P-T1 provides direct interchangeability with the RG1005N-1131-P-T1 without design modification. The CPF0402B1K13E1 is mechanically and electrically compatible but with relaxed tolerance and temperature coefficient specifications. Circuit performance impact depends on application sensitivity to these parameter variations.
