Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012P-1820-W-T1 is determined by strict equivalence in the following electrical and mechanical parameters:

Critical Parameters for Direct Substitution:

• Resistance value: 182 Ohms
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Composition: Thin Film
• Automotive qualification: AEC-Q200
• Operating temperature range: -55°C ~ 155°C
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

Parameters Permitting Variation:

• Tolerance: ±0.05% (main part) to ±0.02% (upgraded alternatives)
• Temperature coefficient: ±25ppm/°C (main part) to ±5ppm/°C or ±10ppm/°C (upgraded alternatives)
• Packaging format: Bulk or Tape & Reel (TR)
• Product status: Obsolete (main part) to Active (substitute parts)

All identified substitute parts maintain identical resistance, power rating, package dimensions, and automotive qualification. Variations in tolerance and temperature coefficient represent performance enhancements rather than deviations from core specifications.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Identical Specifications):

RG2012P-1820-W-T5 provides direct electrical and mechanical equivalence to the RG2012P-1820-W-T1. Both parts share identical resistance, tolerance, power rating, temperature coefficient, and package specifications. The primary difference is packaging format (Tape & Reel versus bulk) and active product status. This part is suitable for applications requiring no performance enhancement beyond the original specification.

Enhanced Performance Alternatives:

RG2012N-1820-W-T1 offers improved temperature stability with ±10ppm/°C coefficient while maintaining ±0.05% tolerance. This part is appropriate for applications where reduced temperature drift is beneficial without requiring the highest precision grade.

RG2012V-1820-W-T1 and RG2012V-1820-W-T5 provide enhanced performance with ±5ppm/°C temperature coefficient and ±0.05% tolerance. These parts are suitable for precision applications requiring superior temperature stability. The T1 and T5 designations indicate different packaging formats (Tape & Reel variants).

RG2012V-1820-P-T1 represents the highest precision option with ±0.02% tolerance and ±5ppm/°C temperature coefficient. This part is appropriate for applications requiring the tightest resistance tolerance and minimal temperature drift.

All substitute parts maintain AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 rating. Selection should be based on application requirements for tolerance and temperature stability, as well as packaging format compatibility with assembly processes.

Frequently Asked Questions (FAQ)

Q: Can RG2012P-1820-W-T5 be used as a direct replacement for RG2012P-1820-W-T1?

A: Yes. Both parts are electrically and mechanically identical with 182 Ohm resistance, ±0.05% tolerance, 0.125W power rating, and 0805 package. The primary difference is packaging format (Tape & Reel versus bulk). Component-level performance is equivalent.

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

A: The RG2012N series features ±10ppm/°C temperature coefficient, while the RG2012V series features ±5ppm/°C temperature coefficient. Both maintain ±0.05% tolerance (except RG2012V-1820-P-T1 which is ±0.02%). The V series provides superior temperature stability for precision applications.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All listed substitute parts carry AEC-Q200 automotive qualification, anti-sulfur construction, and are suitable for automotive applications.

Q: What does the T1 and T5 designation indicate?

A: T1 and T5 designations indicate different packaging formats. T1 represents standard Tape & Reel packaging, while T5 represents an alternative Tape & Reel configuration. Both are suitable for automated assembly processes.

Q: Can higher precision parts (±0.02% tolerance) be used in place of ±0.05% tolerance specifications?

A: Yes. Higher precision parts (RG2012V-1820-P-T1 with ±0.02% tolerance) are compatible with applications designed for ±0.05% tolerance. The tighter tolerance represents an enhancement that does not compromise compatibility.

Q: Is the RG2012P-1820-W-T1 still available for new designs?

A: No. The RG2012P-1820-W-T1 is classified as obsolete. Active equivalent parts include RG2012P-1820-W-T5, RG2012N-1820-W-T1, RG2012V-1820-P-T1, RG2012V-1820-W-T1, and RG2012V-1820-W-T5. New designs should specify one of these active alternatives.

Q: Do all substitute parts meet ROHS3 compliance?

A: Yes. All listed substitute parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the environmental compliance profile of the original part.
