Key Parameters

Substitute Part Grouping Explanation

Substitution for the RCP0505B75R0JS3 is determined by strict equivalence in the following parameters:

• Resistance value: 75 Ohms (exact match required)
• Power rating: 1.4W (exact match required)
• Package / Case: 0505 (1412 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)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Tolerance may vary within the acceptable range for the application. RoHS compliance status and inventory availability do not affect electrical or mechanical substitutability.

Parameter Comparison

Engineering Selection Recommendations

RCP0505W75R0GEB qualifies as a direct substitute for RCP0505B75R0JS3 based on electrical and mechanical parameter equivalence. The substitute part features improved tolerance specification (±2% versus ±5%), which provides enhanced precision without compromising compatibility. Both components maintain identical power rating, package dimensions, thermal characteristics, and moisture resistance properties.

RCP0505W75R0GEB carries ROHS3 compliance certification, whereas RCP0505B75R0JS3 is RoHS non-compliant. Selection between these parts should account for regulatory requirements applicable to the end application.

Frequently Asked Questions (FAQ)

Q: Can RCP0505W75R0GEB replace RCP0505B75R0JS3 in existing designs?

A: Yes. Both parts share identical resistance value, power rating, package dimensions, thermal operating range, and moisture sensitivity classification. Mechanical and electrical compatibility is confirmed.

Q: What is the difference in tolerance between these parts?

A: RCP0505B75R0JS3 specifies ±5% tolerance, while RCP0505W75R0GEB specifies ±2% tolerance. The tighter tolerance of the substitute part does not create incompatibility; it represents improved precision.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.055" L x 0.050" W (1.40mm x 1.27mm) with maximum seated height of 0.025" (0.64mm). PCB footprint and assembly compatibility are identical.

Q: Does RoHS compliance affect substitutability?

A: RoHS compliance status does not affect electrical or mechanical substitutability. Selection should be based on regulatory requirements of the target application and end market.

Q: Are both parts available in Tape & Reel packaging?

A: Yes. Both RCP0505B75R0JS3 and RCP0505W75R0GEB are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.
