RG1005P-4530-B-T1 Equivalent & Substitute Parts

Part Overview

The RG1005P-4530-B-T1 is a 453 Ohm ±0.1% thin film chip resistor in 0402 (1005 Metric) package rated for 0.063W (1/16W) power dissipation. This Susumu component features anti-sulfur coating and automotive AEC-Q200 qualification, designed for high-precision applications requiring tight tolerance and temperature stability across -55°C to 155°C operating range. The part is currently obsolete, necessitating identification of functionally equivalent active alternatives that maintain electrical and mechanical compatibility for direct board-level substitution.

Substitute Part Grouping Explanation

Substitution eligibility for the RG1005P-4530-B-T1 is determined by the following mandatory parameters:

Critical Matching Parameters:

Resistance value: 453 Ohms (exact match required)
Package type: 0402 (1005 Metric) (exact match required)
Power rating: 0.063W minimum (equal or greater acceptable)
Composition: Thin Film (required for performance characteristics)
Operating temperature range: -55°C to 155°C minimum (equal or wider acceptable)
RoHS3 compliance (required for regulatory alignment)

Tolerance and Temperature Coefficient Considerations: Substitute parts with equal or tighter tolerance specifications (±0.1% or better) are direct equivalents. Parts with tighter temperature coefficients (lower ppm/°C values) represent performance upgrades. Parts with looser tolerance or temperature coefficient specifications are not suitable substitutes.

Automotive Qualification: AEC-Q200 rating is a feature specification. Substitutes with AEC-Q200 qualification maintain automotive-grade reliability; substitutes without this rating remain functionally compatible but lack automotive qualification.

Engineering Selection Recommendations

Direct Equivalent (Same Electrical and Mechanical Specifications):

RG1005P-4530-B-T5 is the direct active equivalent to RG1005P-4530-B-T1. Both parts share identical electrical specifications (453 Ω, ±0.1%, 0.063W, ±25ppm/°C) and mechanical package (0402). The primary difference is packaging format (Tape & Reel vs. bulk) and active product status. This part maintains full AEC-Q200 automotive qualification and anti-sulfur coating.

ERA-2AEB4530X (Panasonic ERA-2A series) provides electrical and mechanical equivalence with identical specifications and AEC-Q200 qualification. This part is suitable for direct substitution in automotive applications.

CPF0402B453RE1 (TE Connectivity) matches all electrical and mechanical parameters but lacks AEC-Q200 automotive qualification. This part is suitable for non-automotive applications requiring equivalent electrical performance.

Performance Upgrade Options (Tighter Tolerance or Temperature Coefficient):

RG1005V-4530-B-T5 upgrades temperature coefficient performance from ±25ppm/°C to ±5ppm/°C while maintaining ±0.1% tolerance and AEC-Q200 qualification. This part is suitable for applications requiring improved temperature stability.

RG1005N-4530-W-T1 and RG1005P-4530-W-T5 provide tighter tolerance (±0.05%) with maintained or improved temperature coefficient performance. These parts are suitable for precision applications requiring tolerance better than ±0.1%.

RG1005V-4530-P-T1 represents the highest precision option with ±0.02% tolerance and ±5ppm/°C temperature coefficient, suitable for ultra-precision measurement and calibration circuits.

Operating Temperature Limitation:

MCS04020D4530BE100 (Vishay Beyschlag) has a reduced upper operating temperature limit of 125°C compared to the 155°C specification of the original part. This part is suitable only for applications where the 125°C maximum is acceptable.

Frequently Asked Questions (FAQ)

Q: Can RG1005P-4530-B-T5 be used as a direct replacement for RG1005P-4530-B-T1?

A: Yes. RG1005P-4530-B-T5 is electrically and mechanically identical to RG1005P-4530-B-T1, with the same 453 Ω resistance, ±0.1% tolerance, 0.063W power rating, ±25ppm/°C temperature coefficient, and 0402 package. The primary difference is packaging format (Tape & Reel) and active product status. Both parts maintain AEC-Q200 automotive qualification and anti-sulfur coating.

Q: What is the difference between Susumu RG series variants (P, N, V)?

A: The letter designation indicates temperature coefficient performance. RG1005P series has ±25ppm/°C, RG1005N series has ±10ppm/°C, and RG1005V series has ±5ppm/°C. All variants maintain the same 453 Ω resistance and 0402 package. Selection depends on application requirements for temperature stability.

Q: Are non-AEC-Q200 parts suitable for automotive applications?

A: Parts without AEC-Q200 qualification lack automotive-grade reliability testing and qualification. CPF0402B453RE1 and MCS04020D4530BE100 are not recommended for automotive applications where AEC-Q200 compliance is required. ERA-2AEB4530X and all Susumu RG series parts maintain AEC-Q200 qualification.

Q: Can I use a part with tighter tolerance than the original specification?

A: Yes. Parts with tighter tolerance specifications (±0.05% or ±0.02%) are functionally compatible and represent performance upgrades. They provide better resistance accuracy without compromising circuit compatibility.

Q: What is the significance of the packaging designation (T1 vs. T5)?

A: T1 and T5 designations indicate different packaging formats. T1 typically represents standard packaging, while T5 represents Tape & Reel format. Both formats contain identical components; the difference is in delivery and handling method. Electrical and mechanical specifications remain identical.

Q: Is the MCS04020D4530BE100 suitable for all applications requiring the RG1005P-4530-B-T1?

A: MCS04020D4530BE100 is suitable only for applications where the maximum operating temperature does not exceed 125°C. The original part specification extends to 155°C. For applications requiring the full -55°C to 155°C temperature range, this part is not suitable.

Q: What is the difference between anti-sulfur and standard thin film resistors?

A: Anti-sulfur coating protects the resistor element from sulfur contamination in industrial environments. The RG1005P-4530-B-T1 includes anti-sulfur coating. ERA-2AEB4530X also includes this feature. CPF0402B453RE1 and MCS04020D4530BE100 do not specify anti-sulfur coating. For applications in sulfur-prone environments, anti-sulfur variants are recommended.

Q: Can I substitute ERA-2AEB4530X for RG1005P-4530-B-T1 in automotive applications?

A: Yes. ERA-2AEB4530X maintains identical electrical specifications (453 Ω, ±0.1%, 0.063W, ±25ppm/°C), mechanical package (0402), and AEC-Q200 automotive qualification. This part is a direct equivalent suitable for automotive applications.
