Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012P-683-W-T5 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 68 kOhms (exact match required)
• Tolerance: ±0.05% (exact match required)
• Power rating: 0.125W / 1/8W (exact match required)
• Composition: Thin Film (exact match required)

Mechanical Parameters:

• Package format: 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 & Environmental Parameters:

• Automotive qualification: AEC-Q200 (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• RoHS3 compliance (exact match required)
• Moisture Sensitivity Level: 1 (exact match required)

Substitute parts must satisfy all parameters listed above. Variations in temperature coefficient, seated height, or anti-sulfur coating do not disqualify substitution when all critical parameters are met.

Parameter Comparison

Engineering Selection Recommendations

The ERA-6ARW683V (Panasonic Electronic Components) is a direct electrical and mechanical equivalent to the RG2012P-683-W-T5 (Susumu). Both components meet identical specifications for resistance value, tolerance, power rating, package format, operating temperature range, and AEC-Q200 automotive qualification.

Selection Basis:

Both parts are active in production status and carry ROHS3 compliance with MSL 1 rating. The ERA-6ARW683V offers superior temperature coefficient performance (±10ppm/°C versus ±25ppm/°C), which provides enhanced stability across the full operating temperature range. The seated height difference (0.024" versus 0.020") is within acceptable mechanical tolerance for 0805 package applications and does not impact PCB layout or assembly compatibility.

The ERA-6ARW683V is suitable for direct substitution in applications where the RG2012P-683-W-T5 is specified, provided that the slightly increased seated height does not conflict with specific board-level clearance constraints.

Frequently Asked Questions (FAQ)

Q: Can the ERA-6ARW683V replace the RG2012P-683-W-T5 in production assemblies?

A: Yes. Both components are electrically and mechanically equivalent across all critical parameters: 68 kOhms ±0.05%, 0.125W power rating, 0805 package, AEC-Q200 automotive qualification, and -55°C ~ 155°C operating range. The ERA-6ARW683V is a direct substitute.

Q: What is the significance of the temperature coefficient difference?

A: The ERA-6ARW683V exhibits a temperature coefficient of ±10ppm/°C compared to ±25ppm/°C for the RG2012P-683-W-T5. This means the Panasonic part maintains tighter resistance stability across temperature variations, which is advantageous for precision analog circuits. Both values remain within acceptable limits for standard applications.

Q: Does the seated height difference affect PCB assembly?

A: The ERA-6ARW683V has a maximum seated height of 0.024" (0.60mm) versus 0.020" (0.50mm) for the RG2012P-683-W-T5. This 0.004" (0.10mm) difference is negligible for standard PCB layouts and does not impact reflow soldering, component placement, or clearance requirements in typical 0805 applications. Verify clearance only if the design includes height-critical constraints.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the RG2012P-683-W-T5 and ERA-6ARW683V carry AEC-Q200 automotive qualification and are rated for -55°C ~ 155°C operation, meeting automotive reliability and environmental stress requirements.

Q: What is the packaging format for both parts?

A: Both components are supplied in Tape & Reel (TR) format in 0805 (2012 Metric) package. This format is standard for automated PCB assembly processes.

Q: Are both parts RoHS compliant?

A: Yes. Both the RG2012P-683-W-T5 and ERA-6ARW683V are ROHS3 compliant with Moisture Sensitivity Level 1 (unlimited shelf life), meeting environmental and regulatory requirements for commercial and industrial applications.
