RG1608P-4752-C-T5 Equivalent & Substitute Parts

Part Overview

The RG1608P-4752-C-T5 is a 47.5 kOhms ±0.25% thin film chip resistor in 0603 (1608 Metric) package rated for 0.1W (1/10W) power dissipation. Manufactured by Susumu, this component features anti-sulfur coating and automotive AEC-Q200 qualification, suitable for high-reliability applications across -55°C to 155°C operating temperature range. The part is currently obsolete, necessitating identification of functionally equivalent active alternatives that maintain electrical and mechanical compatibility with existing designs.

Substitute Part Grouping Explanation

Substitution compatibility for the RG1608P-4752-C-T5 is determined by the following critical parameters:

Mandatory Matching Parameters:

Resistance value: 47.5 kOhms
Package type: 0603 (1608 Metric)
Power rating: 0.1W (1/10W) minimum
Composition: Thin Film
Operating temperature range: -55°C to 155°C minimum

Acceptable Variation Parameters:

Tolerance: Equal to or tighter than ±0.25%
Temperature coefficient: Equal to or lower than ±25ppm/°C
Automotive qualification: AEC-Q200 preferred for high-reliability applications
Anti-sulfur coating: Preferred for automotive environments

Substitute parts are classified into two categories:

Upgrade Substitutes: Active production parts with improved electrical specifications (tighter tolerance and/or lower temperature coefficient) while maintaining or exceeding all other performance requirements.

Direct Substitutes: Active production parts with equivalent electrical specifications and package compatibility, offering functional interchangeability.

Engineering Selection Recommendations

Primary Recommendation for Automotive AEC-Q200 Applications:

For applications requiring maintained automotive qualification and anti-sulfur protection, select from Susumu RG series active alternatives:

RG1608P-4752-B-T5: Direct functional equivalent with ±0.1% tolerance, highest inventory availability (77,644 units)
RG1608N-4752-B-T5: Improved tolerance (±0.1%) and lower temperature coefficient (±10ppm/°C)
RG1608N-4752-W-T1: Superior tolerance (±0.05%) and lower temperature coefficient (±10ppm/°C)

Alternative for Non-Automotive Applications:

For applications without AEC-Q200 requirement:

RT0603BRD0747K5L (YAGEO): Equivalent ±0.1% tolerance, full temperature range compatibility, 15,915 units in stock
ERA-3AEB4752V (Panasonic): AEC-Q200 qualified alternative with ±0.1% tolerance, 22,410 units in stock

For Extended Power Margin:

6-2176089-1 (TE Connectivity): Higher power rating (0.167W vs 0.1W) provides thermal margin, though AEC-Q200 qualification is not available

Operating Temperature Constraint:

MCT06030D4752BP500 (Vishay Beyschlag) operates only to 125°C maximum, making it unsuitable for applications requiring the full -55°C to 155°C range of the original part.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with tighter tolerance than the original RG1608P-4752-C-T5?

A: Yes. Tighter tolerance specifications (±0.1% or ±0.05%) are fully compatible and provide improved circuit accuracy. The original ±0.25% tolerance establishes the maximum acceptable tolerance; tighter tolerances do not compromise functionality.

Q: Is the 0603 package dimension identical across all substitute parts?

A: The 0603 (1608 Metric) package designation is standardized. All listed substitutes use this package. Minor dimensional variations exist (length 1.55mm to 1.60mm, height 0.50mm to 0.55mm), but these fall within PCB footprint design tolerances and do not affect mechanical compatibility.

Q: What is the difference between RG1608P and RG1608N series?

A: The RG1608P series maintains ±25ppm/°C temperature coefficient, while RG1608N series offers improved ±10ppm/°C temperature coefficient. Both series are anti-sulfur and AEC-Q200 qualified. Selection depends on circuit temperature stability requirements.

Q: Can I substitute the RG1608P-4752-C-T5 with RT0603CRD0747K5L in automotive applications?

A: RT0603CRD0747K5L matches the original tolerance (±0.25%) and power rating (0.1W) with full temperature range compatibility. However, it lacks AEC-Q200 automotive qualification and anti-sulfur coating. Use only in non-automotive or non-critical applications.

Q: Why does MCT06030D4752BP500 have a lower maximum operating temperature?

A: MCT06030D4752BP500 is rated to 125°C maximum, compared to 155°C for the original part. This 30°C reduction limits its use to applications where the upper temperature bound does not exceed 125°C. Verify circuit thermal requirements before selection.

Q: What is the inventory status for immediate procurement?

A: RG1608P-4752-B-T5 (Susumu) offers the highest availability with 77,644 units in stock. RT0603BRD0747K5L (YAGEO) provides 15,915 units. All listed substitutes are currently in active production and available for immediate delivery.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the environmental compliance profile of the original RG1608P-4752-C-T5.
