Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012N-73R2-C-T5 is determined by the following critical parameters that must remain constant across all equivalent parts:

Fixed Parameters (Non-Negotiable):

• Resistance value: 73.2 Ohms
• Package type: 0805 (2012 Metric)
• Power rating: 0.125W (1/8W)
• Composition: Thin Film
• Temperature coefficient: ±10ppm/°C
• Operating temperature range: -55°C to 155°C
• Features: Anti-Sulfur, Automotive AEC-Q200
• RoHS3 compliance
• MSL 1 rating

Variable Parameters (Substitution Basis):

• Tolerance: The main part specifies ±0.25%. Substitute parts with tighter tolerances (±0.1% or ±0.05%) are electrically compatible and represent upgrades in precision.
• Product status: The main part is obsolete. Active substitute parts ensure continued component availability.
• Packaging format: The main part uses cut tape; substitutes are available in Tape & Reel (TR) format, which is standard for production environments.

All three substitute parts maintain identical electrical performance, mechanical fit, and environmental ratings while offering improved tolerance specifications and active product status.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

All three substitute parts are direct functional equivalents to the RG2012N-73R2-C-T5. Selection among substitutes is based on tolerance requirements and product availability:

RG2012N-73R2-B-T5 (±0.1% Tolerance)

• Provides improved tolerance specification over the main part
• Maintains all electrical and mechanical compatibility
• Active product status with 1122 units in stock
• Suitable for applications requiring tighter resistance tolerance than ±0.25%

RG2012N-73R2-W-T1 (±0.05% Tolerance)

• Highest precision option with ±0.05% tolerance
• Meets all electrical and mechanical requirements
• Active product status with 773 units in stock
• Appropriate for precision analog circuits and measurement applications

RG2012N-73R2-W-T5 (±0.05% Tolerance)

• Equivalent precision to RG2012N-73R2-W-T1 with ±0.05% tolerance
• Active product status with 654 units in stock
• Identical electrical performance and mechanical fit
• Suitable for applications requiring highest resistance accuracy

All substitute parts carry AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 rating, ensuring compatibility with automotive and industrial applications. The transition from cut tape to Tape & Reel packaging aligns with standard production assembly processes.

Frequently Asked Questions (FAQ)

Q: Can RG2012N-73R2-B-T5, RG2012N-73R2-W-T1, and RG2012N-73R2-W-T5 be used interchangeably with RG2012N-73R2-C-T5?

A: Yes. All three substitute parts maintain identical resistance value (73.2 Ohms), power rating (0.125W), package type (0805), composition (thin film), temperature coefficient (±10ppm/°C), operating temperature range (-55°C to 155°C), and automotive AEC-Q200 qualification. The substitutes offer tighter tolerance specifications, which represent improvements in precision rather than deviations from the original specification.

Q: What is the difference between the three substitute parts?

A: The primary difference is tolerance specification. RG2012N-73R2-B-T5 provides ±0.1% tolerance, while both RG2012N-73R2-W-T1 and RG2012N-73R2-W-T5 provide ±0.05% tolerance. All other electrical and mechanical parameters are identical. The selection between W-T1 and W-T5 variants depends on packaging format requirements and inventory availability.

Q: Why is the main part RG2012N-73R2-C-T5 listed as obsolete?

A: Product obsolescence is determined by manufacturer discontinuation. The substitute parts listed are active products from the same manufacturer series, ensuring continued availability for new designs and replacement applications.

Q: Are the substitute parts compatible with existing PCB designs for RG2012N-73R2-C-T5?

A: Yes. All substitute parts use the identical 0805 (2012 Metric) package with matching footprint dimensions (0.079" L x 0.049" W, 2.00mm x 1.25mm) and height (0.020" maximum seated height). No PCB layout modifications are required.

Q: What is the difference between cut tape and Tape & Reel (TR) packaging?

A: Cut tape is supplied in individual strips for manual handling and small-quantity applications. Tape & Reel (TR) format provides components on continuous reel tape suitable for automated pick-and-place assembly equipment used in production environments. Both formats contain identical components; packaging format selection depends on assembly process requirements.

Q: Do all substitute parts meet automotive qualification requirements?

A: Yes. All substitute parts carry AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 (unlimited moisture sensitivity) rating, matching the environmental and reliability standards of the original part.

Q: Which substitute part should be selected for precision-critical applications?

A: For applications requiring the highest resistance accuracy, either RG2012N-73R2-W-T1 or RG2012N-73R2-W-T5 with ±0.05% tolerance is appropriate. For applications where ±0.1% tolerance is sufficient, RG2012N-73R2-B-T5 provides an intermediate option. All three maintain the same temperature coefficient and operating range.
