Key Parameters

Substitute Part Grouping Explanation

Substitution of the RCP2512W100RJTP is determined by the following critical parameters:

• Resistance Value: Must be 100 Ohms
• Power Rating: Must be 4.6W minimum
• Package / Case: Must be 2512 (6432 Metric) for mechanical and thermal compatibility
• Composition: Thick Film construction
• Temperature Coefficient: ±150ppm/°C
• Operating Temperature Range: -65°C ~ 155°C
• Moisture Resistance: Required feature

The RCP2512W100RGEB qualifies as a direct substitute because it maintains all critical electrical and mechanical parameters while offering improved tolerance specification (±2% versus ±5%).

Parameter Comparison

Engineering Selection Recommendations

The RCP2512W100RGEB serves as a direct substitute for the RCP2512W100RJTP with the following considerations:

Tolerance Improvement: The substitute part offers ±2% tolerance compared to the original ±5%, providing tighter resistance value control without any electrical or mechanical compromise.

Compliance Advantage: The RCP2512W100RGEB is ROHS3 compliant, whereas the RCP2512W100RJTP is RoHS non-compliant. Selection of the substitute part satisfies RoHS3 regulatory requirements where applicable.

Electrical Equivalence: Both parts maintain identical power rating (4.6W), temperature coefficient (±150ppm/°C), and operating temperature range (-65°C ~ 155°C), ensuring functional interchangeability in circuit applications.

Mechanical Compatibility: Both parts use the 2512 (6432 Metric) package with identical physical dimensions (0.250" L x 0.124" W / 6.35mm x 3.15mm) and maximum seated height (0.025" / 0.64mm), allowing direct PCB footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can RCP2512W100RGEB replace RCP2512W100RJTP in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent. The substitute offers improved tolerance (±2% vs ±5%) and RoHS3 compliance without requiring design modifications.

Q: What is the significance of the tolerance difference between ±5% and ±2%?

A: Tolerance defines the acceptable deviation from the nominal 100 Ohm resistance value. The ±2% specification on the substitute part ensures resistance values fall within a narrower range (98–102 Ohms) compared to the ±5% specification (95–105 Ohms), providing greater precision in circuit performance.

Q: Are the physical packages identical?

A: Yes. Both parts use the 2512 (6432 Metric) package with identical dimensions: 0.250" L x 0.124" W (6.35mm x 3.15mm) and maximum seated height of 0.025" (0.64mm). PCB footprints are directly compatible.

Q: What does RoHS3 compliance mean for the substitute part?

A: RoHS3 compliance indicates the RCP2512W100RGEB meets Restriction of Hazardous Substances regulations, restricting the use of specified hazardous materials. This is required for many applications, particularly in consumer electronics and regulated industries.

Q: Do both parts have the same moisture resistance properties?

A: Yes. Both the RCP2512W100RJTP and RCP2512W100RGEB feature moisture-resistant thick film construction with MSL rating of 1 (Unlimited), indicating no moisture sensitivity limitations during storage or handling.

Q: Can these parts be used interchangeably in high-precision applications?

A: The RCP2512W100RGEB is preferred for high-precision applications due to its ±2% tolerance specification. The RCP2512W100RJTP with ±5% tolerance is suitable for general-purpose applications where tighter tolerance is not required.
