Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG1608V-4220-C-T5 is determined by strict equivalence in the following parameters:

Critical Parameters (Must Match):

• Resistance value: 422 Ohms
• Power rating: 0.1W (1/10W)
• Package: 0603 (1608 Metric)
• Composition: Thin Film
• Temperature coefficient: ±5ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive AEC-Q200 qualification
• Anti-sulfur coating
• RoHS3 compliance

Allowable Variation:

• Tolerance: Substitute parts may feature tighter (lower) tolerance values than the original ±0.25% specification. Tighter tolerances are electrically and mechanically compatible with designs specified for ±0.25% tolerance.

All substitute parts listed maintain identical physical dimensions (0.063" L x 0.031" W / 1.60mm x 0.80mm), height (0.020" / 0.50mm maximum seated), and termination configuration (2 terminations).

Parameter Comparison

Engineering Selection Recommendations

RG1608V-4220-B-T5 (±0.1% Tolerance) This substitute provides improved tolerance specification (±0.1% versus ±0.25%) while maintaining all other electrical and mechanical parameters. Active product status ensures ongoing availability and manufacturing support. Suitable for applications where the original tolerance specification is acceptable and improved precision is beneficial.

RG1608V-4220-W-T1 (±0.05% Tolerance) This substitute offers enhanced tolerance performance (±0.05%) with active product status. Recommended for designs requiring tighter tolerance control than the original specification while maintaining full AEC-Q200 automotive qualification and anti-sulfur protection.

RG1608V-4220-P-T1 (±0.02% Tolerance) This substitute represents the highest precision option with ±0.02% tolerance specification. Active product status and full compliance certifications make this suitable for precision measurement and calibration circuits where maximum tolerance control is required.

All substitute parts maintain identical physical form factor, thermal characteristics, and automotive reliability ratings. Selection among substitutes depends on application tolerance requirements and design margin considerations.

Frequently Asked Questions (FAQ)

Q: Can RG1608V-4220-B-T5, RG1608V-4220-W-T1, or RG1608V-4220-P-T1 be used as direct replacements for RG1608V-4220-C-T5?

A: Yes. All substitute parts are electrically and mechanically compatible. They maintain identical resistance value (422 Ohms), power rating (0.1W), package configuration (0603), and operating temperature range (-55°C to 155°C). The substitutes feature tighter tolerance specifications, which are compatible with designs specified for ±0.25% tolerance.

Q: What is the difference between the substitute parts?

A: The substitute parts differ only in tolerance specification. RG1608V-4220-B-T5 provides ±0.1% tolerance, RG1608V-4220-W-T1 provides ±0.05% tolerance, and RG1608V-4220-P-T1 provides ±0.02% tolerance. All other parameters, including resistance value, power rating, package, and temperature characteristics, are identical.

Q: Why is the original RG1608V-4220-C-T5 marked as obsolete?

A: Product obsolescence indicates the manufacturer has discontinued active production. Substitute parts with active product status provide equivalent functionality with improved specifications and assured supply chain continuity.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All substitute parts carry automotive AEC-Q200 qualification, anti-sulfur coating, and ROHS3 compliance identical to the original part.

Q: Can I use a substitute with tighter tolerance in a circuit designed for ±0.25% tolerance?

A: Yes. Tighter tolerance specifications are compatible with designs specified for looser tolerances. A component with ±0.1%, ±0.05%, or ±0.02% tolerance will meet or exceed the performance requirements of a circuit designed for ±0.25% tolerance.

Q: Are the physical dimensions identical across all parts?

A: Yes. All parts share identical dimensions: 0.063" L x 0.031" W (1.60mm x 0.80mm) with maximum seated height of 0.020" (0.50mm). PCB footprints and assembly processes are interchangeable.

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

A: All parts, including the original and substitutes, have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.
