RG1608P-7872-B-T5 Equivalent & Substitute Parts

Part Overview

The RG1608P-7872-B-T5 is a 78.7 kOhms ±0.1% thin film chip resistor manufactured by Susumu in 0603 (1608 Metric) package format. This surface-mount device is rated for 0.1W (1/10W) power dissipation and features anti-sulfur coating with automotive AEC-Q200 qualification. The component operates across -55°C to 155°C with a temperature coefficient of ±25ppm/°C. Substitute parts are identified when equivalent electrical specifications, mechanical compatibility, and compliance certifications align with the original design requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

Mandatory Matching Criteria:

• Resistance value: 78.7 kOhms
• Tolerance: ±0.1%
• Package / Case: 0603 (1608 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±25ppm/°C
• Number of Terminations: 2
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation:

• Power Rating: Equal to or greater than 0.1W
• Operating Temperature Range: Must encompass or extend the -55°C to 155°C minimum range
• Physical dimensions: Minor variations within standard 0603 package tolerances
• Automotive certification (AEC-Q200): Preferred but not mandatory for all substitutes

All four substitute parts meet the mandatory matching criteria. Variations in power rating and operating temperature range are noted in the parameter comparison table.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility):

ERA-3AEB7872V (Panasonic) and TNPW060378K7BEEA (Vishay Dale) are direct functional equivalents to the RG1608P-7872-B-T5. Both maintain automotive AEC-Q200 certification, anti-sulfur coating (Vishay Dale), and identical electrical specifications. These parts are suitable for applications requiring automotive-grade reliability and environmental protection.

Secondary Substitutes (Electrical Equivalence):

RT0603BRD0778K7L (YAGEO) matches all electrical and mechanical specifications but lacks automotive AEC-Q200 certification. This part is suitable for non-automotive applications where the original AEC-Q200 requirement is not mandated.

8-2176089-0 (TE Connectivity) provides higher power rating (0.167W versus 0.1W) while maintaining all other electrical parameters. This part accommodates applications with increased thermal margin but does not carry automotive AEC-Q200 certification.

Compliance Considerations:

All substitute parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Moisture sensitivity level remains at MSL 1 (Unlimited) across all options, indicating no special moisture handling requirements during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can RT0603BRD0778K7L replace RG1608P-7872-B-T5 in automotive applications?

A: RT0603BRD0778K7L is electrically and mechanically equivalent but does not carry automotive AEC-Q200 certification. Use in automotive applications depends on whether AEC-Q200 qualification is a design requirement. If AEC-Q200 is mandatory, select ERA-3AEB7872V or TNPW060378K7BEEA instead.

Q: What is the significance of the higher power rating in 8-2176089-0?

A: The 8-2176089-0 is rated for 0.167W (1/6W) compared to the original 0.1W (1/10W). This higher power rating provides additional thermal headroom in the same 0603 package. The part remains electrically equivalent and can be used as a direct substitute where thermal margin is beneficial.

Q: Are there dimensional differences between substitute parts?

A: Minor dimensional variations exist within standard 0603 package tolerances. The RG1608P-7872-B-T5, RT0603BRD0778K7L, and ERA-3AEB7872V share identical length and width (0.063" x 0.031"). The TE Connectivity 8-2176089-0 and Vishay Dale TNPW060378K7BEEA have slightly reduced length (0.061") and the Vishay part has increased width (0.033"). All parts fit standard 0603 footprints. Height variations (0.020" to 0.022") are within PCB assembly clearance specifications.

Q: Which substitute offers the widest operating temperature range?

A: TNPW060378K7BEEA (Vishay Dale) operates across -55°C to 175°C, extending 20°C above the original specification. All other substitutes maintain the -55°C to 155°C range. Select the Vishay part for applications requiring extended high-temperature performance.

Q: Do all substitutes maintain the ±0.1% tolerance specification?

A: Yes. All four substitute parts maintain ±0.1% tolerance, matching the original RG1608P-7872-B-T5 specification. Tolerance is a mandatory matching criterion for substitution eligibility.

Q: Is anti-sulfur coating available in all substitutes?

A: Anti-sulfur coating is specified for RG1608P-7872-B-T5 (Susumu) and TNPW060378K7BEEA (Vishay Dale). The YAGEO RT0603BRD0778K7L, Panasonic ERA-3AEB7872V, and TE Connectivity 8-2176089-0 do not list anti-sulfur as a feature. For applications in sulfur-rich environments, select parts with explicit anti-sulfur specification.

Q: Are all substitutes available in Tape & Reel packaging?

A: Yes. All substitute parts are supplied in Tape & Reel (TR) packaging, matching the original component packaging format for automated assembly compatibility.
