RCP2512B100RJTP Equivalent & Substitute Parts

Part Overview

The RCP2512B100RJTP is a 100 Ohms ±5% 4.6W chip resistor in 2512 (6432 Metric) package manufactured by Vishay Dale. This thick film, moisture-resistant component operates across -65°C to 155°C and is currently in active production status. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required, particularly when enhanced tolerance specifications or improved compliance certifications are necessary for specific applications.

Substitute Part Grouping Explanation

Substitution of the RCP2512B100RJTP is permissible with parts maintaining identical electrical specifications in resistance value (100 Ohms) and power rating (4.6W), identical mechanical compatibility through the 2512 package footprint, and matching thermal characteristics (±150ppm/°C temperature coefficient, -65°C to 155°C operating range). The critical substitution parameters are:

• Resistance value: 100 Ohms (exact match required)
• Power rating: 4.6W (exact match required)
• Package: 2512 (6432 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±150ppm/°C (exact match required)
• Operating temperature range: -65°C ~ 155°C (exact match required)

Tolerance and RoHS compliance may vary between equivalent parts without affecting core substitutability, provided the above parameters remain constant.

Parameter Comparison

Engineering Selection Recommendations

The RCP2512W100RGEB serves as a direct electrical and mechanical substitute for the RCP2512B100RJTP. Both components share identical resistance, power rating, package dimensions, and thermal operating parameters. The RCP2512W100RGEB provides improved tolerance specification (±2% versus ±5%) and achieves ROHS3 compliance, whereas the RCP2512B100RJTP is RoHS non-compliant. Selection between these parts depends on application requirements for regulatory compliance and tolerance precision. Both parts maintain active production status and equivalent moisture resistance characteristics.

Frequently Asked Questions (FAQ)

Q: Can RCP2512W100RGEB replace RCP2512B100RJTP in existing designs?

A: Yes. Both components are electrically and mechanically equivalent, sharing identical 100 Ohms resistance, 4.6W power rating, 2512 package footprint, and thermal specifications. The substitute part offers tighter tolerance (±2%) and improved RoHS compliance.

Q: What are the key compatibility factors for substitution?

A: Substitution requires matching resistance value (100 Ohms), power rating (4.6W), package type (2512), composition (Thick Film), temperature coefficient (±150ppm/°C), and operating temperature range (-65°C to 155°C). These parameters determine functional and mechanical interchangeability.

Q: Does the tolerance difference affect circuit performance?

A: Tolerance differences (±5% versus ±2%) affect resistor value accuracy. Applications requiring tighter value control should specify the ±2% tolerance part. Both tolerances fall within standard thick film resistor specifications.

Q: Are there packaging differences between these parts?

A: Both parts are supplied in Tape & Reel (TR) packaging with identical 2512 (6432 Metric) footprints, dimensions (0.250" L x 0.124" W), and maximum seated height (0.025"). No packaging modifications are required for substitution.

Q: What is the significance of RoHS compliance differences?

A: RCP2512W100RGEB meets ROHS3 compliance standards, while RCP2512B100RJTP does not. Applications subject to RoHS regulatory requirements must use the compliant substitute part.
