Substitute Part Grouping Explanation

Substitution of the RG1608V-101-W-T1 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 100 Ohms
• Package / Case: 0603 (1608 Metric)
• Power rating: 0.1W (1/10W)
• Composition: Thin Film
• Temperature coefficient: ±5ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Features: Anti-Sulfur, Automotive AEC-Q200
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

Allowable Variation:

• Tolerance: The substitute part RG1608V-101-P-T1 features ±0.02% tolerance, which is tighter (more stringent) than the ±0.05% specification of the main part. Tighter tolerance specifications are acceptable substitutes as they meet or exceed the original requirement.

The RG1608V-101-P-T1 qualifies as a direct substitute because it maintains all mandatory parameters while providing improved tolerance performance.

Parameter Comparison

Engineering Selection Recommendations

Both the RG1608V-101-W-T1 and RG1608V-101-P-T1 are active products from Susumu with full AEC-Q200 automotive qualification and RoHS3 compliance. Selection between these parts is based on tolerance requirements and application precision needs.

RG1608V-101-W-T1 (±0.05% Tolerance): Suitable for general precision applications where ±0.05% tolerance meets circuit specifications. This part provides cost-effective performance for standard analog and measurement circuits.

RG1608V-101-P-T1 (±0.02% Tolerance): Appropriate for applications requiring tighter tolerance control. The improved ±0.02% tolerance specification supports higher-precision measurement, instrumentation, and signal conditioning circuits where tolerance stack-up must be minimized.

Both parts maintain identical electrical performance across temperature coefficient, operating temperature range, and power dissipation. Physical dimensions and PCB footprint compatibility are identical, enabling direct substitution without layout modifications. Both parts carry MSL 1 rating, indicating unlimited shelf life under standard storage conditions.

Frequently Asked Questions (FAQ)

Q: Can RG1608V-101-P-T1 be used as a direct replacement for RG1608V-101-W-T1?

A: Yes. The RG1608V-101-P-T1 is a direct substitute. It maintains identical resistance value, package, power rating, temperature coefficient, and operating temperature range. The tighter ±0.02% tolerance of the substitute part exceeds the ±0.05% specification of the original part, making it suitable for all applications where the RG1608V-101-W-T1 is specified.

Q: Are there any PCB layout or footprint differences between these parts?

A: No. Both parts use the 0603 (1608 Metric) package with identical dimensions of 0.063" L x 0.031" W (1.60mm x 0.80mm) and maximum seated height of 0.020" (0.50mm). PCB footprints are identical, and no layout modifications are required for substitution.

Q: What is the difference between the W and P designations in the part numbers?

A: The W and P designations indicate different tolerance grades. The W-suffix part (RG1608V-101-W-T1) specifies ±0.05% tolerance, while the P-suffix part (RG1608V-101-P-T1) specifies ±0.02% tolerance. Both parts are thin film resistors with identical temperature coefficients and operating characteristics.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the RG1608V-101-W-T1 and RG1608V-101-P-T1 carry AEC-Q200 qualification and anti-sulfur coating, making them suitable for automotive electronic systems. Both parts are RoHS3 compliant and carry MSL 1 rating.

Q: What is the temperature coefficient specification, and does it differ between these parts?

A: Both parts specify ±5ppm/°C temperature coefficient and operate across the identical temperature range of -55°C to 155°C. Temperature stability performance is equivalent between the two parts.

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

A: The RG1608V-101-P-T1 with ±0.02% tolerance is preferred for high-precision measurement applications where tolerance stack-up is critical. The RG1608V-101-W-T1 with ±0.05% tolerance is suitable for applications where this tolerance specification meets circuit requirements. Selection depends on the specific tolerance budget of the circuit design.
