Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012N-393-B-T5 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 39 kOhms
• Package / Case: 0805 (2012 Metric)
• Power rating: 0.125W (1/8W)
• Composition: Thin Film
• Temperature coefficient: ±10ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive AEC-Q200 qualification
• RoHS3 compliance

Allowable Variation:

• Tolerance: Parts with ±0.05% tolerance are acceptable upgrades to the ±0.1% specification
• Manufacturer: Susumu and Panasonic Electronic Components parts are interchangeable
• Height - Seated (Max): Variation between 0.020" (0.50mm) and 0.024" (0.60mm) is acceptable within 0805 package specification

Substitute parts are grouped into direct equivalents (matching tolerance) and upgrades (improved tolerance specification).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Substitutes:

RG2012N-393-W-T1 and ERA-6ARB393V are direct functional equivalents to the RG2012N-393-B-T5. Both maintain the ±0.1% tolerance specification and are suitable for applications requiring identical electrical performance. RG2012N-393-W-T1 is manufactured by Susumu with the same anti-sulfur feature. ERA-6ARB393V is manufactured by Panasonic Electronic Components and maintains all critical electrical and thermal parameters. Both parts carry AEC-Q200 automotive qualification and ROHS3 compliance.

Upgrade Substitutes:

RG2012N-393-W-T1 and ERA-6ARW393V offer improved tolerance specification at ±0.05%, providing tighter resistance accuracy compared to the ±0.1% main part. These upgrades are suitable for applications requiring enhanced precision without modification to circuit design or PCB layout. Both upgrade parts maintain identical power rating, package configuration, temperature coefficient, and operating temperature range. AEC-Q200 qualification and ROHS3 compliance are preserved.

Cross-Manufacturer Compatibility:

Susumu RG series and Panasonic ERA-6A series parts are interchangeable within the specified parameter constraints. Height variation between 0.020" (0.50mm) and 0.024" (0.60mm) is within acceptable 0805 package tolerance and does not affect PCB assembly or electrical performance.

Frequently Asked Questions (FAQ)

Q: Can ERA-6ARB393V be used as a direct replacement for RG2012N-393-B-T5?

A: Yes. ERA-6ARB393V is a direct equivalent substitute. Both parts share identical resistance (39 kOhms), tolerance (±0.1%), power rating (0.125W), package (0805), composition (thin film), temperature coefficient (±10ppm/°C), operating temperature range (-55°C ~ 155°C), and AEC-Q200 automotive qualification. The 0.004" (0.04mm) height difference is within 0805 package specification and does not affect functionality.

Q: What is the difference between the main part and upgrade parts?

A: The upgrade parts (RG2012N-393-W-T1 and ERA-6ARW393V) feature ±0.05% tolerance compared to ±0.1% tolerance of the main part. All other electrical and mechanical parameters remain identical. Upgrade parts provide tighter resistance accuracy for precision-critical applications.

Q: Are all substitute parts automotive-qualified?

A: Yes. All substitute parts listed carry AEC-Q200 automotive qualification, matching the main part specification.

Q: Can parts from different manufacturers be mixed in the same design?

A: Yes. Susumu RG2012N series and Panasonic ERA-6A series parts are cross-compatible within the specified parameter constraints. Both manufacturers meet identical electrical, thermal, and compliance requirements.

Q: What is the significance of the height difference between Susumu and Panasonic parts?

A: Susumu parts have a maximum seated height of 0.020" (0.50mm), while Panasonic parts have a maximum seated height of 0.024" (0.60mm). Both measurements fall within the 0805 (2012 Metric) package specification and do not affect PCB assembly, component placement, or electrical performance.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level), matching the main part specification.

Q: Can ERA-6ARW393V be used in place of RG2012N-393-B-T5 without circuit modification?

A: Yes. ERA-6ARW393V is an upgrade substitute with improved ±0.05% tolerance. All electrical parameters, package configuration, and thermal characteristics are compatible. No circuit modification is required.
