Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG3216N-1272-B-T5 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 12.7 kOhms
• Tolerance: ±0.1%
• Power rating: 0.25W (1/4W)
• Temperature coefficient: ±10ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters:

• Package type: 1206 (3216 Metric)
• Number of terminations: 2
• Physical dimensions: 0.126" L x 0.063" W (3.20mm x 1.60mm)

Compliance & Quality Parameters:

• Composition: Thin Film
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3
• Moisture sensitivity: MSL 1

The ERA-8ARB1272V from Panasonic Electronic Components meets all critical electrical and mechanical parameters. Both parts are thin film resistors with identical resistance, tolerance, power rating, and temperature characteristics. Both are AEC-Q200 qualified for automotive applications and ROHS3 compliant. The physical package dimensions are equivalent, with only the seated height differing by 0.008" (0.20mm), which does not affect functional compatibility in standard PCB assembly processes.

Parameter Comparison

Engineering Selection Recommendations

Both the RG3216N-1272-B-T5 and ERA-8ARB1272V are active production parts with full AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts is based on availability and supply chain requirements rather than technical performance differences.

The RG3216N-1272-B-T5 features anti-sulfur coating, which provides enhanced environmental protection in corrosive atmospheres. The ERA-8ARB1272V does not specify anti-sulfur treatment in the provided documentation.

Both parts are suitable for applications requiring high precision (±0.1% tolerance), stable temperature performance (±10ppm/°C), and automotive-grade reliability across the -55°C to 155°C operating range.

The 0.008" (0.20mm) difference in seated height between the two parts does not impact PCB assembly compatibility or electrical performance in standard surface mount applications.

Frequently Asked Questions (FAQ)

Q: Can ERA-8ARB1272V be used as a direct replacement for RG3216N-1272-B-T5?

A: Yes. Both parts are electrically and mechanically equivalent with identical resistance (12.7 kOhms), tolerance (±0.1%), power rating (0.25W), temperature coefficient (±10ppm/°C), and package format (1206). Both are AEC-Q200 qualified and ROHS3 compliant.

Q: Are there differences in physical dimensions between these parts?

A: The length and width are identical at 0.126" x 0.063" (3.20mm x 1.60mm). The seated height differs by 0.008" (0.20mm), with the RG3216N-1272-B-T5 at 0.020" (0.50mm) and the ERA-8ARB1272V at 0.028" (0.70mm). This difference does not affect standard PCB assembly or component placement.

Q: What is the significance of the anti-sulfur feature on the RG3216N-1272-B-T5?

A: Anti-sulfur coating provides protection against sulfur-containing environmental contaminants that can degrade resistor performance. This feature is beneficial in applications exposed to industrial or corrosive atmospheres. The ERA-8ARB1272V does not specify this feature in the provided documentation.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the RG3216N-1272-B-T5 and ERA-8ARB1272V carry AEC-Q200 automotive qualification, indicating compliance with automotive reliability and quality standards.

Q: What is the moisture sensitivity level for these parts?

A: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These parts can be stored and handled without special moisture control measures.

Q: Can these parts be used interchangeably in high-precision circuits?

A: Yes. Both parts meet ±0.1% tolerance and ±10ppm/°C temperature coefficient specifications, making them suitable for precision analog circuits, measurement equipment, and applications requiring stable resistor values across temperature variations.
