Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG2012P-6493-B-T1 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 649 kOhms
• Tolerance: ±0.1%
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±25ppm/°C
• Operating Temperature Range: -55°C ~ 155°C (minimum)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation Parameters:

• Power Rating: Equal to or greater than 0.125W
• Height - Seated (Max): Variation acceptable within standard 0805 package specifications
• Packaging format: Original packaging type may differ (bulk vs. Tape & Reel)
• Automotive certification: AEC-Q200 preferred but not mandatory for non-automotive applications
• Anti-sulfur feature: Preferred but not mandatory

Substitute parts must maintain electrical performance across the specified operating temperature range and comply with RoHS3 requirements. Parts with enhanced power ratings or improved temperature coefficients are classified as upgrades.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Specifications):

RG2012P-6493-B-T5 is the direct equivalent to the obsolete RG2012P-6493-B-T1. Both are manufactured by Susumu with identical electrical specifications. The primary difference is packaging format (Tape & Reel vs. Bulk) and active product status. This part is recommended for direct replacement in production environments.

Automotive-Qualified Alternatives:

ERA-6AEB6493V (Panasonic) and TNPW0805649KBEEA / TNPW0805649KBEEN (Vishay Dale) are AEC-Q200 qualified alternatives suitable for automotive applications. ERA-6AEB6493V maintains identical electrical specifications to the original part. TNPW series components offer enhanced power rating (0.26W vs. 0.125W) and extended operating temperature range (-55°C ~ 175°C), providing design margin for thermal stress conditions.

General Industrial Alternative:

RT0805BRD07649KL (YAGEO) provides electrical equivalence without automotive certification. This part is suitable for non-automotive applications where AEC-Q200 qualification is not required.

Upgrade Option:

RP73D2A649KBTDF (TE Connectivity) offers improved temperature coefficient (±15ppm/°C vs. ±25ppm/°C), providing enhanced stability across the operating temperature range. This component is recommended for precision applications requiring superior temperature performance.

All substitute parts comply with ROHS3 requirements and maintain MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can RG2012P-6493-B-T5 be used as a direct replacement for RG2012P-6493-B-T1?

A: Yes. RG2012P-6493-B-T5 is electrically and mechanically identical to RG2012P-6493-B-T1. Both components share the same resistance value (649 kOhms), tolerance (±0.1%), power rating (0.125W), temperature coefficient (±25ppm/°C), and operating temperature range (-55°C ~ 155°C). The only difference is packaging format and product status. RG2012P-6493-B-T5 is currently active and available.

Q: What is the difference between the Susumu RG series and the Panasonic ERA-6A series?

A: Both series meet identical electrical specifications for this 649 kOhm value: ±0.1% tolerance, 0.125W power rating, ±25ppm/°C temperature coefficient, and -55°C ~ 155°C operating range. Both are AEC-Q200 qualified. The primary differences are manufacturer, physical height (0.50mm vs. 0.60mm seated), and inventory availability. Selection between these parts depends on supply chain requirements and manufacturer preference.

Q: Why do the Vishay Dale TNPW parts have different power ratings?

A: TNPW0805649KBEEA and TNPW0805649KBEEN are rated for 0.26W power dissipation, compared to 0.125W for the original RG2012P-6493-B-T1. This higher power rating does not affect substitution eligibility, as the parts can safely handle the original design's power requirements. The enhanced rating provides additional thermal margin and is suitable for applications with higher power dissipation requirements. These parts also feature extended operating temperature range (-55°C ~ 175°C) and moisture-resistant coating.

Q: Is the YAGEO RT0805BRD07649KL suitable for automotive applications?

A: RT0805BRD07649KL is not AEC-Q200 qualified. It is suitable for general industrial and consumer applications where automotive certification is not required. For automotive applications, use ERA-6AEB6493V, TNPW0805649KBEEA, or TNPW0805649KBEEN instead.

Q: What does the RP73D2A649KBTDF upgrade offer?

A: RP73D2A649KBTDF provides improved temperature coefficient performance (±15ppm/°C vs. ±25ppm/°C), resulting in superior stability across temperature variations. This upgrade is recommended for precision measurement circuits, reference networks, and applications where temperature-induced resistance drift must be minimized. All other electrical parameters remain equivalent to the original part.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and maintain MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing processes and storage conditions.

Q: What is the physical size difference between substitute parts?

A: All parts use the 0805 (2012 Metric) package with identical length (0.079" / 2.00mm) and width (0.049" / 1.25mm). Seated height varies slightly: RG2012P-6493-B-T1 (0.50mm), ERA-6AEB6493V (0.60mm), RT0805BRD07649KL (0.60mm), TNPW series (0.55mm), and RP73D2A649KBTDF (0.65mm). These variations are within standard 0805 package tolerances and do not affect PCB layout compatibility.

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

A: Yes. All substitute parts meet identical electrical specifications and package requirements. Mixing manufacturers is acceptable from an electrical standpoint. However, design documentation should specify approved part numbers to maintain consistency and traceability in production.
