Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RG1608P-53R6-B-T5 are qualified based on the following criteria:

Mandatory Matching Parameters:

• Resistance value: 53.6 Ohms
• Tolerance: ±0.1%
• Package / Case: 0603 (1608 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±25ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: MSL 1

Allowable Variation Parameters:

• Power Rating: Equal to or greater than 0.1W (1/10W)
• Automotive Rating: AEC-Q200 qualification preferred; absence does not disqualify substitution
• Physical dimensions: Minor variations within package class tolerance acceptable
• Manufacturer: Different manufacturers permitted if all electrical parameters match

The identified substitute parts meet all mandatory matching parameters. Variations in power rating and specific feature sets are noted in the parameter comparison table.

Engineering Selection Recommendations

ERA-3AEB53R6V (Panasonic Electronic Components)

This substitute part provides direct electrical and mechanical equivalence to the RG1608P-53R6-B-T5. Both components share identical resistance, tolerance, power rating, package format, temperature coefficient, and operating temperature range. The ERA-3AEB53R6V carries AEC-Q200 automotive qualification and ROHS3 compliance. Physical dimensions are identical. This part is suitable for direct substitution in automotive and general industrial applications. Inventory availability is 11,525 units.

RP73PF1J53R6BTDF (TE Connectivity Passive Product)

This substitute part matches all critical electrical parameters: resistance value, tolerance, temperature coefficient, and operating temperature range. The package format is 0603 (1608 Metric) with compatible physical dimensions. The power rating is 0.167W (1/6W), which exceeds the 0.1W requirement of the original part, providing additional thermal margin. This part does not carry explicit AEC-Q200 automotive qualification; however, it meets ROHS3 compliance and MSL 1 requirements. This part is suitable for applications where higher power dissipation capability is beneficial. Inventory availability is 885 units.

Both substitute parts are active in production status and maintain full regulatory compliance with ROHS3 and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can ERA-3AEB53R6V be used as a direct replacement for RG1608P-53R6-B-T5?

A: Yes. The ERA-3AEB53R6V matches all electrical specifications (53.6 Ohms ±0.1%, 0.1W, ±25ppm/°C, -55°C to 155°C) and package format (0603). Both parts carry AEC-Q200 automotive qualification and ROHS3 compliance. Physical dimensions are identical.

Q: What is the difference between the RP73PF1J53R6BTDF and the original RG1608P-53R6-B-T5?

A: The RP73PF1J53R6BTDF has a higher power rating (0.167W versus 0.1W) and does not carry explicit AEC-Q200 automotive qualification. All other electrical parameters are identical. The higher power rating provides additional thermal capability without affecting circuit performance.

Q: Are all three parts interchangeable on the same PCB?

A: Yes, all three parts use the 0603 (1608 Metric) package format with compatible footprints. Physical dimensions are within acceptable tolerance for standard 0603 PCB pads. Height variations (0.50mm to 0.55mm) are within normal assembly process capability.

Q: Which substitute part should be selected for automotive applications?

A: The ERA-3AEB53R6V is recommended for automotive applications as it carries explicit AEC-Q200 qualification matching the original part. The RP73PF1J53R6BTDF does not specify AEC-Q200 qualification.

Q: Do all parts meet environmental compliance requirements?

A: Yes. All three parts are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and are classified as EAR99 for export purposes. HTSUS code 8533.21.0030 applies to all parts.

Q: What is the tolerance specification, and why is it important?

A: All three parts are specified at ±0.1% tolerance, which is a precision-grade thin film resistor classification. This tight tolerance is critical for applications requiring high accuracy in resistance value and is maintained across all substitute options.

Q: Can the RP73PF1J53R6BTDF be used in place of the RG1608P-53R6-B-T5 in high-temperature applications?

A: Yes. The RP73PF1J53R6BTDF operates across the same temperature range (-55°C to 155°C) with identical temperature coefficient (±25ppm/°C). The higher power rating does not affect temperature performance.
