Key Parameters

Substitute Part Grouping Explanation

Substitution between RCP0505B25R0GS3 and RCP0505W25R0GEB is valid based on the following criteria:

Electrical Parameters (Identical):

• Resistance value: 25 Ohms
• Tolerance: ±2%
• Power rating: 1.4W
• Temperature coefficient: ±150ppm/°C
• Operating temperature range: -65°C ~ 155°C

Mechanical Parameters (Identical):

• Package type: 0505 (1412 Metric)
• Physical dimensions: 0.055" L x 0.050" W (1.40mm x 1.27mm)
• Maximum seated height: 0.025" (0.64mm)
• Number of terminations: 2

Material & Construction (Identical):

• Composition: Thick Film
• Features: Moisture Resistant
• Moisture Sensitivity Level: 1 (Unlimited)

The primary difference between these parts is packaging format (Tape & Reel vs. Cut Tape & Digi-Reel®) and RoHS compliance status, which do not affect electrical or mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both RCP0505B25R0GS3 and RCP0505W25R0GEB are electrically and mechanically equivalent and may be selected interchangeably for applications requiring a 25 Ohm ±2% 1.4W 0505 chip resistor.

RCP0505W25R0GEB is the preferred selection for new designs or applications subject to RoHS3 compliance requirements. This part maintains all electrical and mechanical specifications while meeting current regulatory standards.

RCP0505B25R0GS3 remains suitable for applications where RoHS compliance is not mandated or for legacy system maintenance where the original specification must be preserved.

Selection between these parts should be based on:

• Regulatory compliance requirements (RoHS3)
• Packaging format requirements (Tape & Reel vs. Cut Tape & Digi-Reel®)
• Inventory and lead time availability

Frequently Asked Questions (FAQ)

Q: Are RCP0505B25R0GS3 and RCP0505W25R0GEB electrically identical?

A: Yes. Both parts have identical resistance (25 Ohms), tolerance (±2%), power rating (1.4W), temperature coefficient (±150ppm/°C), and operating temperature range (-65°C ~ 155°C).

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. Both parts share identical mechanical specifications including package type (0505), physical dimensions (0.055" L x 0.050" W), and seated height (0.025" max). They are pin-compatible and footprint-compatible.

Q: What is the difference between these two part numbers?

A: The primary differences are packaging format (Tape & Reel vs. Cut Tape & Digi-Reel®) and RoHS compliance status (non-compliant vs. ROHS3 compliant). Electrical and mechanical performance are identical.

Q: Which part should I specify for a new design?

A: RCP0505W25R0GEB is recommended for new designs due to ROHS3 compliance alignment with current regulatory standards.

Q: Does packaging format affect component performance?

A: No. Packaging format (Tape & Reel vs. Cut Tape & Digi-Reel®) affects handling, storage, and assembly logistics only. Electrical and mechanical performance remain identical.

Q: Are both parts currently in production?

A: Yes. Both RCP0505B25R0GS3 and RCP0505W25R0GEB are active products from Vishay Dale.
