Substitute Part Grouping Explanation

Substitute parts for the RG1005P-2551-B-T5 are qualified based on the following critical parameters that must match or exceed the main part specifications:

Mandatory Matching Parameters:

• Resistance value: 2.55 kOhms
• Tolerance: ±0.1%
• Package: 0402 (1005 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±25ppm/°C
• Number of Terminations: 2
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variations:

• Power rating may be equal to or greater than 0.063W
• Operating temperature range may be equal to or extend beyond -55°C ~ 155°C
• Automotive AEC-Q200 rating is optional but preferred for automotive applications
• Physical height may vary within package constraints (0.014" to 0.016" maximum seated height)

All identified substitute parts meet these criteria and are suitable for direct replacement in applications where the RG1005P-2551-B-T5 is specified.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active production components with ROHS3 compliance and identical core electrical specifications (2.55 kOhms, ±0.1% tolerance, ±25ppm/°C temperature coefficient, thin film composition). Selection among these alternatives is based on the following criteria:

For Automotive Applications: The RG1005P-2551-B-T5 (Susumu), ERA-2AEB2551X (Panasonic), and TNPW04022K55BEED (Vishay Dale) carry AEC-Q200 automotive qualification. These parts are suitable for automotive-grade applications requiring formal qualification documentation.

For Extended Temperature Range: The TNPW04022K55BEED (Vishay Dale) operates to 175°C, exceeding the standard -55°C ~ 155°C range of other alternatives. This part is applicable where elevated temperature performance is required.

For Higher Power Dissipation: The TNPW04022K55BEED (Vishay Dale) is rated at 0.13W, providing increased power handling capacity compared to the 0.063W rating of other alternatives. This part accommodates applications with higher power requirements within the same package footprint.

For Standard Applications: The CPF0402B2K55E1 (TE Connectivity) and RT0402BRD072K55L (YAGEO) provide equivalent performance for non-automotive applications where AEC-Q200 qualification is not required. Both maintain identical electrical specifications and package compatibility.

For PCB Layout Considerations: The CPF0402B2K55E1 (TE Connectivity) and RT0402BRD072K55L (YAGEO) feature a maximum seated height of 0.014" (0.35mm), compared to 0.016" (0.40mm) for other alternatives. These parts are preferred where PCB clearance is constrained.

Frequently Asked Questions (FAQ)

Q: Can the CPF0402B2K55E1 be used as a direct replacement for the RG1005P-2551-B-T5?

A: Yes. The CPF0402B2K55E1 matches all critical electrical parameters: 2.55 kOhms resistance, ±0.1% tolerance, ±25ppm/°C temperature coefficient, 0.063W power rating, and 0402 package. Both are thin film composition with ROHS3 compliance and MSL 1. The primary difference is the absence of AEC-Q200 automotive qualification on the CPF0402B2K55E1. For non-automotive applications, this part is fully compatible.

Q: What is the difference between the TNPW04022K55BEED and other substitute parts?

A: The TNPW04022K55BEED differs in two specifications: power rating (0.13W versus 0.063W) and maximum operating temperature (175°C versus 155°C). The higher power rating and extended temperature range make this part suitable for applications requiring greater thermal performance. All other electrical and mechanical parameters remain identical to the main part.

Q: Are all substitute parts available in Tape & Reel (TR) packaging?

A: Yes. All substitute parts listed are supplied in Tape & Reel (TR) packaging, matching the packaging format of the RG1005P-2551-B-T5.

Q: Which substitute part is recommended for automotive applications?

A: For automotive applications, the ERA-2AEB2551X (Panasonic) and TNPW04022K55BEED (Vishay Dale) are qualified to AEC-Q200 standard, matching the automotive qualification of the RG1005P-2551-B-T5. The ERA-2AEB2551X maintains identical specifications, while the TNPW04022K55BEED provides additional power rating and temperature range.

Q: Do all substitute parts have the same physical dimensions?

A: All substitute parts share identical length and width dimensions (0.039" L x 0.020" W / 1.00mm x 0.50mm) and are packaged in 0402 (1005 Metric) format. Maximum seated height varies between 0.014" (0.35mm) for CPF0402B2K55E1 and RT0402BRD072K55L, and 0.016" (0.40mm) for RG1005P-2551-B-T5, ERA-2AEB2551X, and TNPW04022K55BEED. This variation is within standard 0402 package tolerances and does not affect PCB assembly compatibility in most applications.

Q: What is the moisture sensitivity level for all parts?

A: All parts, including the main part and all substitutes, are rated MSL 1 (Unlimited). This classification indicates no moisture sensitivity restrictions and unlimited shelf life under standard storage conditions.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts are ROHS3 compliant, matching the environmental compliance status of the RG1005P-2551-B-T5.
