Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RG2012P-182-W-T5 are qualified based on the following criteria:

Electrical Parameters (Critical for Substitution):

• Resistance value: 1.8 kOhms (exact match required)
• Tolerance: ±0.05% or better (tighter tolerance acceptable)
• Power rating: 0.125W minimum (equal or higher acceptable)
• Composition: Thin film (maintains performance characteristics)

Mechanical Parameters (Critical for Substitution):

• Package: 0805 (2012 Metric) form factor
• Termination count: 2 terminations
• Physical dimensions: Compatible with 0805 footprint

Environmental & Compliance Parameters (Required for Substitution):

• Operating temperature range: -55°C ~ 155°C minimum
• Automotive rating: AEC-Q200 required
• RoHS status: ROHS3 compliant
• Moisture sensitivity: MSL 1 acceptable

Two substitute parts meet these criteria and are listed below.

Engineering Selection Recommendations

RG2012V-182-P-T1 (Susumu)

This substitute offers improved tolerance specification (±0.02% versus ±0.05%) and superior temperature coefficient (±5ppm/°C versus ±25ppm/°C). Both parts are manufactured by Susumu and share identical mechanical dimensions, power rating, and package configuration. The RG2012V-182-P-T1 maintains anti-sulfur coating and AEC-Q200 automotive qualification. This part is suitable for applications requiring tighter resistance tolerance and improved temperature stability while maintaining full compatibility with the original design footprint.

ERA-6ARW182V (Panasonic Electronic Components)

This substitute maintains the same resistance value, tolerance, and power rating as the main part. The ERA-6ARW182V is AEC-Q200 qualified and ROHS3 compliant with identical operating temperature range. The maximum seated height is 0.024" (0.60mm) compared to 0.020" (0.50mm) for the main part; this difference must be evaluated for clearance in space-constrained applications. The temperature coefficient is ±10ppm/°C. This part is suitable for applications where cross-manufacturer sourcing is required for supply chain resilience.

Both substitute parts are actively produced and maintain full electrical and mechanical compatibility within the specified parameters.

Frequently Asked Questions (FAQ)

Q: Can RG2012V-182-P-T1 be used as a direct replacement for RG2012P-182-W-T5?

A: Yes. Both parts share identical resistance value (1.8 kOhms), power rating (0.125W), package (0805), and operating temperature range (-55°C ~ 155°C). The RG2012V-182-P-T1 features tighter tolerance (±0.02% versus ±0.05%) and lower temperature coefficient (±5ppm/°C versus ±25ppm/°C), making it functionally compatible and electrically superior for the same footprint.

Q: Can ERA-6ARW182V be used as a direct replacement for RG2012P-182-W-T5?

A: Yes, with one mechanical consideration. The ERA-6ARW182V matches the electrical specifications (1.8 kOhms, ±0.05%, 0.125W, 0805 package) and maintains AEC-Q200 qualification. The maximum seated height is 0.024" (0.60mm) versus 0.020" (0.50mm) for the main part. Verify clearance in applications with height constraints before substitution.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: (1) Resistance value and tolerance, (2) Power rating, (3) Package type and physical dimensions, (4) Operating temperature range, (5) Automotive AEC-Q200 qualification, and (6) RoHS compliance status. All substitute parts must match or exceed these parameters.

Q: Are both substitute parts actively produced?

A: Yes. Both RG2012V-182-P-T1 and ERA-6ARW182V are listed as active products with current inventory availability.

Q: Does the anti-sulfur coating difference between parts affect substitution?

A: The RG2012P-182-W-T5 and RG2012V-182-P-T1 both feature anti-sulfur coating. The ERA-6ARW182V does not specify anti-sulfur coating. If anti-sulfur protection is a design requirement, use RG2012V-182-P-T1 or the main part. If anti-sulfur coating is not specified as a requirement, ERA-6ARW182V is compatible.

Q: What is the difference in temperature coefficient between these parts?

A: The RG2012P-182-W-T5 has ±25ppm/°C, RG2012V-182-P-T1 has ±5ppm/°C, and ERA-6ARW182V has ±10ppm/°C. Lower temperature coefficient indicates better resistance stability across the operating temperature range. Applications requiring high temperature stability should prioritize RG2012V-182-P-T1.
