RG1608P-3571-D-T5 Equivalent & Substitute Parts

Part Overview

The RG1608P-3571-D-T5 is a 3.57 kOhms ±0.5% 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, suitable for applications requiring precision resistive elements in compact form factors. The part is active in production with 997 units currently in stock.

Equivalent and substitute parts are identified based on matching electrical specifications (resistance value, tolerance, power rating), mechanical compatibility (package size, termination count), and environmental ratings (operating temperature range, compliance certifications). Alternative sources provide equivalent or upgraded performance characteristics within the same package footprint.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility is determined by the following critical parameters:

Electrical Compatibility:

• Resistance value must equal 3.57 kOhms
• Tolerance must be equal to or tighter than ±0.5%
• Power rating must be equal to or greater than 0.1W
• Temperature coefficient must match ±25ppm/°C
• Operating temperature range must encompass -55°C ~ 155°C

Mechanical Compatibility:

• Package must be 0603 (1608 Metric)
• Number of terminations must be 2
• Physical dimensions must be compatible with 0603 footprint specifications

Compliance & Environmental:

• RoHS3 compliance required
• Moisture Sensitivity Level 1 required
• Operating temperature range must support -55°C ~ 155°C minimum

Substitute parts are categorized as follows:

Upgrade Substitutes (Tighter Tolerance): Parts with ±0.1% tolerance provide improved precision while maintaining all other specifications.

Direct Substitutes (Equivalent Specifications): Parts with matching tolerance and power rating from alternative manufacturers.

Cross-Manufacturer Equivalents (Same Electrical & Mechanical): Parts from different manufacturers meeting identical electrical and package requirements.

Parameter Comparison

Engineering Selection Recommendations

For Automotive AEC-Q200 Applications: RG1608P-3571-B-T5 (Susumu) and ERA-3AEB3571V (Panasonic) are qualified substitutes. Both maintain AEC-Q200 certification with improved ±0.1% tolerance. RG1608P-3571-B-T5 offers higher inventory availability (10641 units) and identical anti-sulfur coating. ERA-3AEB3571V provides alternative sourcing from Panasonic with equivalent automotive qualification.

For Non-Automotive Applications with Precision Requirements: RT0603BRD073K57L (YAGEO) provides ±0.1% tolerance in the same 0603 package with highest inventory (14043 units). This part lacks AEC-Q200 certification but meets all electrical and mechanical requirements for general industrial applications.

For Direct Equivalent Replacement (Same Tolerance): RT0603DRD073K57L (YAGEO) matches the ±0.5% tolerance specification with 9260 units available. This part is suitable for applications where tolerance upgrade is not required.

For Higher Power Margin Applications: 5-2176088-9 (TE Connectivity) provides 0.167W power rating versus the 0.1W specification, offering additional thermal headroom. This part carries ±0.1% tolerance and is suitable for applications requiring enhanced power dissipation capability within the same package footprint.

Product Status Consideration: All listed substitute parts maintain Active product status, ensuring continued availability and manufacturing support.

Frequently Asked Questions (FAQ)

Q: Can RT0603DRD073K57L replace RG1608P-3571-D-T5 in automotive applications?

A: RT0603DRD073K57L is electrically and mechanically compatible but lacks AEC-Q200 automotive qualification. For automotive applications requiring AEC-Q200 certification, use RG1608P-3571-B-T5 or ERA-3AEB3571V instead.

Q: What is the difference between ±0.5% and ±0.1% tolerance?

A: Tolerance defines the maximum deviation from the nominal resistance value. ±0.1% tolerance provides tighter precision (narrower acceptable range) compared to ±0.5%. Parts with ±0.1% tolerance are suitable for applications requiring higher accuracy.

Q: Is 5-2176088-9 a direct substitute despite the higher power rating?

A: 5-2176088-9 is mechanically and electrically compatible with higher power capability (0.167W versus 0.1W). The increased power rating does not prevent substitution; it provides additional thermal margin. However, this part lacks AEC-Q200 certification and should not be used in automotive applications requiring that qualification.

Q: Do all substitute parts fit the same PCB footprint?

A: All listed parts use the 0603 (1608 Metric) package. Physical dimensions are within compatible ranges for standard 0603 PCB layouts. Minor dimensional variations (height: 0.020" to 0.022" maximum) do not affect standard surface mount assembly processes.

Q: Which substitute offers the best availability?

A: RT0603BRD073K57L (YAGEO) has the highest inventory at 14043 units. RG1608P-3571-B-T5 (Susumu) offers 10641 units with maintained AEC-Q200 certification.

Q: Are all substitutes RoHS3 compliant?

A: Yes, all listed substitute parts are RoHS3 compliant. All parts also maintain Moisture Sensitivity Level 1 (unlimited shelf life).

Q: What is the temperature coefficient significance?

A: Temperature coefficient ±25ppm/°C indicates resistance value change per degree Celsius. All listed parts share this specification, ensuring consistent thermal performance across the -55°C ~ 155°C operating range.
