Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG2012P-4641-W-T1 is determined by the following critical parameters:

Primary Substitution Criteria:

• Resistance value: 4.64 kOhms (exact match required)
• Package type: 0805 (2012 Metric) (exact match required)
• Power rating: 0.125W (1/8W) (exact match required)
• Composition: Thin Film (exact match required)
• Automotive qualification: AEC-Q200 (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Secondary Substitution Parameters (Allowable Variations):

• Tolerance: ±0.05% or tighter (±0.02% acceptable as upgrade)
• Temperature coefficient: ±25ppm/°C or lower (±10ppm/°C or ±5ppm/°C acceptable as upgrades)
• Packaging format: Tape & Reel (TR) acceptable for bulk applications
• Product status: Active preferred over obsolete

All substitute parts listed maintain identical electrical performance within the specified tolerance and thermal operating window. Variations in temperature coefficient represent improved stability characteristics without affecting functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Identical Specifications): RG2012P-4641-W-T5 provides direct functional equivalence to the RG2012P-4641-W-T1. Both parts share identical electrical specifications (4.64 kOhms ±0.05%, ±25ppm/°C temperature coefficient). The primary difference is product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. Bulk). This part is recommended for immediate replacement in production environments.

Enhanced Stability Alternatives: RG2012N-4641-W-T1, RG2012V-4641-W-T1, and RG2012V-4641-W-T5 offer improved temperature coefficient performance (±10ppm/°C and ±5ppm/°C respectively) while maintaining the ±0.05% tolerance specification. These parts are suitable for applications requiring superior thermal stability without design modification.

Precision Upgrade Option: RG2012V-4641-P-T1 provides the tightest tolerance specification (±0.02%) combined with the lowest temperature coefficient (±5ppm/°C). This part is applicable for precision measurement and calibration circuits where enhanced accuracy is required.

All substitute parts maintain AEC-Q200 automotive qualification, ROHS3 compliance, and identical package dimensions. Selection between alternatives depends on application-specific requirements for temperature stability and tolerance precision.

Frequently Asked Questions (FAQ)

Q: Can RG2012P-4641-W-T5 be used as a direct replacement for RG2012P-4641-W-T1?

A: Yes. Both parts are electrically identical with 4.64 kOhms ±0.05% resistance, 0.125W power rating, and ±25ppm/°C temperature coefficient. The primary difference is packaging format (Tape & Reel vs. Bulk). RG2012P-4641-W-T5 is the recommended replacement due to active product status.

Q: What is the difference between the RG2012N and RG2012V series variants?

A: The RG2012N-4641-W-T1 features a ±10ppm/°C temperature coefficient, while RG2012V variants offer ±5ppm/°C. Both maintain the same 4.64 kOhms ±0.05% resistance specification. The RG2012V series provides superior thermal stability for temperature-sensitive applications.

Q: Is RG2012V-4641-P-T1 compatible with designs specified for RG2012P-4641-W-T1?

A: Yes. RG2012V-4641-P-T1 is fully compatible. It maintains the same 4.64 kOhms resistance value, 0.125W power rating, and 0805 package. The ±0.02% tolerance is tighter than the ±0.05% specification, and the ±5ppm/°C temperature coefficient is superior. No design changes are required.

Q: Does packaging format (Tape & Reel vs. Bulk) affect electrical performance?

A: No. Packaging format affects only handling, storage, and assembly processes. Electrical specifications remain identical regardless of whether the part is supplied in Tape & Reel or Bulk format.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All listed substitute parts carry AEC-Q200 automotive qualification and anti-sulfur construction, maintaining compliance with automotive reliability standards.

Q: What is the significance of the temperature coefficient difference between parts?

A: Temperature coefficient indicates resistance value drift over the operating temperature range. Lower values (±5ppm/°C vs. ±25ppm/°C) represent improved stability. For most applications, both specifications are acceptable. Precision measurement circuits benefit from lower temperature coefficients.

Q: Can I mix different substitute parts in the same design?

A: Yes. All substitute parts are electrically compatible and can be used interchangeably within the same circuit. However, for consistency in production and testing, using a single part number is recommended.
