Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012P-433-W-T1 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 43 kOhms (exact match required)
• Tolerance: ±0.05% (exact match required)
• Power rating: 0.125W minimum (equal or greater acceptable)
• Temperature coefficient: ±25ppm/°C or better (lower values acceptable)
• Operating temperature range: -55°C ~ 155°C minimum (equal or greater range acceptable)

Mechanical Parameters:

• Package / Case: 0805 (2012 Metric) (exact match required)
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm) (exact match required)
• Number of terminations: 2 (exact match required)

Compliance & Certification:

• Composition: Thin Film (exact match required)
• AEC-Q200 automotive qualification (required for automotive applications)
• RoHS3 compliance (required)
• Moisture Sensitivity Level 1 (required)

Substitute parts must satisfy all electrical, mechanical, and compliance requirements. Parts with improved temperature coefficient performance or enhanced features are classified as upgrades while maintaining full backward compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Manufacturer): RG2012P-433-W-T5 is the direct equivalent to RG2012P-433-W-T1, differing only in packaging format (Tape & Reel versus bulk). Both parts are manufactured by Susumu, maintain identical electrical specifications including ±25ppm/°C temperature coefficient, and feature anti-sulfur coating with AEC-Q200 qualification. This part is currently in active production status with 763 units in stock.

Upgraded Equivalent (Enhanced Performance): RG2012N-433-W-T5 is an upgraded variant from Susumu featuring improved temperature coefficient of ±10ppm/°C compared to the original ±25ppm/°C specification. This part maintains all other electrical and mechanical parameters, anti-sulfur coating, and AEC-Q200 automotive qualification. Product status is active with 1009 units in stock.

Cross-Manufacturer Alternatives: ERA-6ARW433V (Panasonic Electronic Components) and RT0805WRB0743KL (YAGEO) are cross-manufacturer substitutes meeting all critical electrical and mechanical requirements. Both parts feature improved ±10ppm/°C temperature coefficient performance. ERA-6ARW433V maintains AEC-Q200 automotive qualification and is available with 2763 units in stock. RT0805WRB0743KL does not carry AEC-Q200 rating and lacks automotive qualification, making it suitable only for non-automotive applications.

For automotive applications requiring AEC-Q200 compliance, selection is limited to RG2012P-433-W-T5, RG2012N-433-W-T5, or ERA-6ARW433V. For general-purpose applications without automotive requirements, RT0805WRB0743KL is a viable alternative.

Frequently Asked Questions (FAQ)

Q: Can RG2012P-433-W-T5 be used as a direct replacement for RG2012P-433-W-T1?

A: Yes. RG2012P-433-W-T5 is electrically and mechanically identical to RG2012P-433-W-T1. The difference is packaging format: RG2012P-433-W-T1 uses bulk packaging while RG2012P-433-W-T5 uses Tape & Reel format. Both parts are manufactured by Susumu with identical specifications.

Q: What is the difference between RG2012P-433-W-T5 and RG2012N-433-W-T5?

A: The primary difference is temperature coefficient. RG2012P-433-W-T5 has ±25ppm/°C while RG2012N-433-W-T5 has ±10ppm/°C. RG2012N-433-W-T5 provides superior temperature stability. All other electrical and mechanical parameters are identical.

Q: Can ERA-6ARW433V be used in automotive applications?

A: Yes. ERA-6ARW433V is manufactured by Panasonic Electronic Components and carries AEC-Q200 automotive qualification. It meets all electrical and mechanical requirements for automotive use.

Q: Why is RT0805WRB0743KL not recommended for automotive applications?

A: RT0805WRB0743KL does not carry AEC-Q200 automotive qualification. While it meets electrical and mechanical specifications, it lacks the automotive-grade certification required for automotive circuit applications.

Q: Are there physical dimension differences between substitute parts?

A: Yes. RG2012P-433-W-T1, RG2012P-433-W-T5, and RG2012N-433-W-T5 have maximum seated height of 0.020" (0.50mm). ERA-6ARW433V and RT0805WRB0743KL have maximum seated height of 0.024" (0.60mm). This 0.004" (0.10mm) difference must be considered for space-constrained PCB layouts.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All parts listed carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Q: Which substitute part offers the best temperature stability?

A: RG2012N-433-W-T5, ERA-6ARW433V, and RT0805WRB0743KL all feature ±10ppm/°C temperature coefficient, providing superior stability compared to the original RG2012P-433-W-T1 specification of ±25ppm/°C.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are RoHS3 compliant and carry REACH Unaffected status.
