RCP0505B75R0JEC Equivalent & Substitute Parts

Part Overview

The RCP0505B75R0JEC is a 75 Ohm ±5% 1.4W chip resistor manufactured by Vishay Dale in the 0505 (1412 Metric) package. This thick film, moisture-resistant component operates across -65°C to 155°C and is ROHS3 compliant with MSL 1 rating. The part is currently active in production with 760 pieces in stock. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required while maintaining the same package footprint and thermal specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCP0505B75R0JEC is determined by strict alignment of 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)
• RoHS Status: ROHS3 Compliant (exact match required)

The tolerance specification (±5% vs. ±2%) represents the only allowable variance. A tighter tolerance (±2%) constitutes an upgrade path and maintains full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the RCP0505B75R0JEC and RCP0505W75R0GEB are active production components from Vishay Dale with ROHS3 compliance and MSL 1 rating. The RCP0505W75R0GEB provides improved tolerance specification (±2% versus ±5%), delivering tighter resistance accuracy within the same electrical and thermal envelope. Both parts are suitable for applications requiring 75 Ohm 1.4W thick film resistors in 0505 package format across the -65°C to 155°C operating range. Selection between these parts depends on tolerance requirements for the specific circuit application.

Frequently Asked Questions (FAQ)

Q: Can RCP0505W75R0GEB replace RCP0505B75R0JEC in existing designs?

A: Yes. The RCP0505W75R0GEB is mechanically and electrically compatible. It occupies the same 0505 (1412 Metric) footprint, delivers identical 1.4W power rating, and operates across the same -65°C to 155°C temperature range. The tighter ±2% tolerance represents an upgrade in accuracy.

Q: What is the primary difference between these two parts?

A: The tolerance specification differs. RCP0505B75R0JEC carries ±5% tolerance, while RCP0505W75R0GEB carries ±2% tolerance. All other electrical, thermal, and mechanical parameters are identical.

Q: Are both parts ROHS3 compliant?

A: Yes. Both RCP0505B75R0JEC and RCP0505W75R0GEB are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Do these parts require different PCB layout considerations?

A: No. Both parts use the 0505 (1412 Metric) package with identical dimensions (0.055" L x 0.050" W, 1.40mm x 1.27mm) and maximum seated height (0.025" / 0.64mm). PCB footprints are interchangeable.

Q: What is the temperature coefficient specification for both parts?

A: Both parts have a temperature coefficient of ±150ppm/°C across the -65°C to 155°C operating range.
