Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters: resistance value (45.3 kOhms), package type (0805 / 2012 Metric), composition (thin film), temperature coefficient (±25ppm/°C), operating temperature range (-55°C ~ 155°C), and environmental compliance (ROHS3, MSL 1).

Substitute parts are grouped into two categories:

Upgrade Substitutes (Tighter Tolerance): Parts with ±0.1% tolerance provide improved precision compared to the ±0.5% specification of the main part. These include RG2012P-4532-B-T5 (Susumu), ERA-6AEB4532V (Panasonic), and RT0805BRD0745K3L (YAGEO). All maintain identical resistance, package, composition, temperature coefficient, and operating temperature range.

Direct Substitute (Higher Power Rating): Part 6-2176093-3 (TE Connectivity) provides a 0.25W (1/4W) power rating upgrade while maintaining ±0.1% tolerance, identical resistance, package, composition, and temperature range. This part does not carry automotive AEC-Q200 certification.

All substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with existing supply chain and assembly processes.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Automotive AEC-Q200 Applications):

RG2012P-4532-B-T5 (Susumu) and ERA-6AEB4532V (Panasonic) are direct functional upgrades with ±0.1% tolerance, maintaining AEC-Q200 automotive qualification. Both parts are active in production with high inventory availability (18,367 and 17,058 units respectively). Selection between these two depends on packaging preference: Susumu offers Tape & Reel format, while Panasonic provides Cut Tape and Digi-Reel options.

For Non-Automotive Applications:

RT0805BRD0745K3L (YAGEO) provides ±0.1% tolerance in Tape & Reel format without automotive certification. This part is suitable for commercial and industrial applications where AEC-Q200 qualification is not required. Inventory availability is 13,068 units.

For Higher Power Dissipation Requirements:

6-2176093-3 (TE Connectivity) offers 0.25W (1/4W) power rating with ±0.1% tolerance. This part does not carry AEC-Q200 certification and is suitable for applications requiring increased thermal headroom. Inventory availability is 1,952 units.

All substitute parts maintain identical package dimensions, composition, temperature coefficient, and environmental compliance ratings. Selection should be based on tolerance requirements, automotive qualification necessity, and packaging format compatibility with assembly processes.

Frequently Asked Questions (FAQ)

Q: Can RG2012P-4532-B-T5 be used as a direct replacement for RG2012P-4532-D-T5?

A: Yes. Both parts share identical resistance (45.3 kOhms), package (0805), power rating (0.125W), composition (thin film), temperature coefficient (±25ppm/°C), and operating temperature range (-55°C ~ 155°C). RG2012P-4532-B-T5 provides tighter tolerance (±0.1% vs ±0.5%) and maintains AEC-Q200 automotive qualification.

Q: What is the difference between the Susumu RG2012P-4532-B-T5 and Panasonic ERA-6AEB4532V?

A: Both parts are functionally equivalent with 45.3 kOhms ±0.1% resistance, 0.125W power rating, and AEC-Q200 certification. The primary difference is packaging format: Susumu provides Tape & Reel, while Panasonic offers Cut Tape and Digi-Reel options. Physical dimensions vary slightly in seated height (0.50mm vs 0.60mm).

Q: Is RT0805BRD0745K3L suitable for automotive applications?

A: RT0805BRD0745K3L does not carry AEC-Q200 automotive certification. It is suitable for commercial and industrial applications. For automotive applications, use RG2012P-4532-B-T5 or ERA-6AEB4532V.

Q: When should 6-2176093-3 be selected over other substitutes?

A: 6-2176093-3 provides 0.25W (1/4W) power rating compared to 0.125W (1/8W) in other parts. Select this part when circuit design requires higher power dissipation capability. Note that this part does not carry AEC-Q200 certification.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed parts (RG2012P-4532-D-T5, RG2012P-4532-B-T5, ERA-6AEB4532V, RT0805BRD0745K3L, and 6-2176093-3) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the impact of tolerance differences on circuit performance?

A: The main part RG2012P-4532-D-T5 has ±0.5% tolerance, while substitute parts offer ±0.1% tolerance. This means substitute parts maintain resistance values within a tighter band. For precision analog circuits, filtering networks, or reference applications, the ±0.1% tolerance provides improved accuracy and reduced circuit drift.

Q: Can packaging format be mixed in production?

A: Packaging format differences (Tape & Reel vs Cut Tape) affect assembly line compatibility and handling. Verify that selected packaging format is compatible with existing pick-and-place equipment and assembly processes before implementation.
