Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG1608P-52R3-D-T5 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 52.3 Ohms
• 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: 1 (Unlimited)

Allowable Variation Parameters:

• Tolerance: ±0.5% or tighter (±0.1% acceptable)
• Power Rating: 0.1W or higher (0.167W acceptable)
• Automotive Rating: AEC-Q200 preferred but not mandatory for all substitutes
• Height - Seated (Max): 0.020" to 0.022" range acceptable

Three substitute parts meet these criteria with variations in tolerance and power rating specifications.

Parameter Comparison

Engineering Selection Recommendations

ERA-3AEB52R3V (Panasonic Electronic Components)

This substitute provides tighter tolerance (±0.1% versus ±0.5%) with identical power rating and AEC-Q200 automotive qualification. The part maintains all electrical and mechanical specifications with higher inventory availability (7697 pieces). Height difference of 0.002" (0.05mm) is within acceptable PCB assembly tolerances. Selection is appropriate for applications requiring improved tolerance performance without power rating changes.

RT0603BRD0752R3L (YAGEO)

This substitute offers ±0.1% tolerance matching with identical 0.1W power rating. The part is ROHS3 compliant with unlimited moisture sensitivity rating. Height specification of 0.022" (0.55mm) is within standard assembly clearance margins. Automotive AEC-Q200 rating is not specified for this part. Selection is suitable for non-automotive applications or where automotive qualification is not a design requirement.

RP73PF1J52R3BTDF (TE Connectivity Passive Product)

This substitute provides ±0.1% tolerance with elevated power rating of 0.167W (1/6W), offering thermal margin above the original 0.1W specification. The part is ROHS3 compliant with unlimited moisture sensitivity. Automotive AEC-Q200 rating is not specified. Height specification of 0.022" (0.55mm) is within acceptable tolerances. Selection is appropriate for applications requiring higher power dissipation capability or thermal headroom within the 0603 package footprint.

Frequently Asked Questions (FAQ)

Q: Can ERA-3AEB52R3V be used as a direct replacement for RG1608P-52R3-D-T5?

A: Yes. The ERA-3AEB52R3V maintains identical resistance value, power rating, package format, temperature coefficient, and operating temperature range. The tighter tolerance (±0.1% versus ±0.5%) represents an improvement in accuracy. Both parts are AEC-Q200 rated and ROHS3 compliant. The 0.002" height difference is within standard PCB assembly tolerances.

Q: What is the difference between the three substitute parts?

A: ERA-3AEB52R3V and RT0603BRD0752R3L both provide ±0.1% tolerance with 0.1W power rating. ERA-3AEB52R3V includes AEC-Q200 automotive qualification; RT0603BRD0752R3L does not. RP73PF1J52R3BTDF offers ±0.1% tolerance with higher 0.167W power rating, suitable for applications requiring additional thermal margin.

Q: Are all substitute parts suitable for automotive applications?

A: ERA-3AEB52R3V carries AEC-Q200 automotive qualification matching the original part. RT0603BRD0752R3L and RP73PF1J52R3BTDF do not specify AEC-Q200 rating. For automotive applications requiring AEC-Q200 compliance, ERA-3AEB52R3V is the appropriate selection.

Q: Does the height difference between parts affect PCB assembly?

A: The original RG1608P-52R3-D-T5 has maximum seated height of 0.020" (0.50mm). All three substitutes have maximum seated height of 0.022" (0.55mm), representing a 0.002" (0.05mm) difference. This variation is within standard PCB assembly clearance specifications and does not affect component placement or soldering processes.

Q: Can RP73PF1J52R3BTDF be used in place of RG1608P-52R3-D-T5 in high-temperature applications?

A: Yes. RP73PF1J52R3BTDF maintains the same operating temperature range (-55°C ~ 155°C) and temperature coefficient (±25ppm/°C) as the original part. The higher power rating (0.167W versus 0.1W) provides additional thermal margin in high-dissipation circuits.

Q: What is the tolerance improvement when using substitute parts?

A: The original RG1608P-52R3-D-T5 specifies ±0.5% tolerance. All three substitute parts offer ±0.1% tolerance, representing a five-fold improvement in accuracy. This tighter tolerance reduces circuit performance variation and improves overall system precision.

Q: Are all parts RoHS3 compliant?

A: Yes. The main part RG1608P-52R3-D-T5 and all three substitute parts (ERA-3AEB52R3V, RT0603BRD0752R3L, RP73PF1J52R3BTDF) are ROHS3 compliant with moisture sensitivity level 1 (unlimited).
