RG1608P-114-W-T1 Equivalent & Substitute Parts

Part Overview

The RG1608P-114-W-T1 is a 110 kOhms ±0.05% thin film chip resistor in 0603 (1608 Metric) package rated for 0.1W power dissipation. Manufactured by Susumu, this component features anti-sulfur coating and automotive AEC-Q200 qualification, designed for high-precision applications requiring tight tolerance specifications. The part is active in production with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent resistance values, power ratings, package dimensions, and automotive certifications align with application requirements while accommodating minor tolerance variations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG1608P-114-W-T1 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 110 kOhms
• Power rating: 0.1W (1/10W)
• Package: 0603 (1608 Metric)
• Composition: Thin Film
• Temperature coefficient: ±25ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive certification: AEC-Q200
• RoHS compliance: ROHS3

Allowable Variation:

• Tolerance: The main part specifies ±0.05%. Substitute parts with equal or wider tolerance (±0.1% or greater) are functionally compatible in applications where the tighter tolerance of the original part is not a design requirement.

The ERA-3AEB114V from Panasonic Electronic Components qualifies as a substitute based on matching all mandatory parameters. The tolerance difference (±0.1% versus ±0.05%) represents a relaxation of specification that does not compromise circuit performance in standard automotive applications.

Engineering Selection Recommendations

RG1608P-114-W-T1 (Primary Selection)

Select this part when circuit design specifications explicitly require ±0.05% tolerance. The anti-sulfur coating provides enhanced reliability in corrosive environments. Active production status ensures long-term availability. ROHS3 compliance and AEC-Q200 automotive qualification support regulated applications.

ERA-3AEB114V (Substitute Selection)

This part is suitable for applications where ±0.1% tolerance meets functional requirements. Panasonic's ERA-3A series maintains identical electrical performance across the specified operating temperature range and power rating. AEC-Q200 qualification and ROHS3 compliance ensure automotive-grade reliability. The 0.002" (0.05mm) height difference is negligible for standard PCB assembly processes. Higher inventory availability (56,840 units) supports production continuity.

Both parts are active products with equivalent compliance certifications and thermal performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can ERA-3AEB114V replace RG1608P-114-W-T1 in all applications?

A: ERA-3AEB114V is compatible in applications where ±0.1% tolerance is acceptable. If circuit design requires ±0.05% tolerance, the RG1608P-114-W-T1 must be used. Both parts share identical resistance, power rating, package, temperature coefficient, and operating range.

Q: What is the significance of the tolerance difference between these parts?

A: The RG1608P-114-W-T1 offers ±0.05% tolerance, while ERA-3AEB114V offers ±0.1%. For a 110 kOhm resistor, this represents a maximum deviation of 5.5 Ohms versus 11 Ohms respectively. Applications with precision analog circuits, reference networks, or tight gain specifications may require the tighter tolerance.

Q: Are the physical dimensions compatible for PCB assembly?

A: Both parts use 0603 (1608 Metric) package with identical length and width (0.063" x 0.031"). The seated height differs by 0.002" (0.05mm), which does not affect standard reflow soldering or component placement processes.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both RG1608P-114-W-T1 and ERA-3AEB114V carry AEC-Q200 automotive qualification and ROHS3 compliance, suitable for automotive and regulated industrial applications.

Q: What is the anti-sulfur coating on the RG1608P-114-W-T1?

A: The anti-sulfur feature on the Susumu part provides enhanced corrosion resistance in environments with hydrogen sulfide exposure. The Panasonic ERA-3AEB114V does not specify this feature. Select the RG1608P-114-W-T1 for applications in corrosive industrial or marine environments.

Q: How do temperature coefficients compare?

A: Both parts specify ±25ppm/°C temperature coefficient with identical -55°C to 155°C operating range. Thermal stability performance is equivalent across the full operating temperature spectrum.
