Key Parameters

Substitute Part Grouping Explanation

The RCP2512W75R0GEB qualifies as a direct substitute for the RCP2512W75R0JS3 based on the following critical parameters:

• Identical resistance value: 75 Ohms
• Identical power rating: 4.6W
• Identical package: 2512 (6432 Metric)
• Identical physical dimensions: 0.250" L x 0.124" W (6.35mm x 3.15mm)
• Identical height: 0.025" (0.64mm)
• Identical composition: Thick Film
• Identical temperature coefficient: ±150ppm/°C
• Identical operating temperature range: -65°C ~ 155°C
• Identical MSL rating: 1 (Unlimited)

The primary difference is tolerance specification: RCP2512W75R0GEB provides ±2% tolerance compared to the ±5% tolerance of the RCP2512W75R0JS3, representing an upgrade in precision. Additionally, RCP2512W75R0GEB is RoHS3 compliant, whereas RCP2512W75R0JS3 is RoHS non-compliant.

Parameter Comparison

Engineering Selection Recommendations

The RCP2512W75R0GEB is a direct functional equivalent to the RCP2512W75R0JS3 with improved tolerance specification and RoHS3 compliance. Selection between these parts depends on application requirements:

Use RCP2512W75R0JS3 when ±5% tolerance meets circuit specifications and RoHS non-compliant components are acceptable.

Use RCP2512W75R0GEB when tighter ±2% tolerance is required or when RoHS3 compliance is mandated by design standards or regulatory requirements. Both parts share identical electrical performance characteristics, power rating, temperature range, and physical footprint, ensuring direct substitution at the PCB assembly level.

Frequently Asked Questions (FAQ)

Q: Can RCP2512W75R0GEB replace RCP2512W75R0JS3 in existing designs?

A: Yes. Both parts are electrically and mechanically identical with the same 75 Ohm resistance, 4.6W power rating, 2512 package, and operating temperature range. The RCP2512W75R0GEB provides improved tolerance (±2% vs ±5%) and RoHS3 compliance.

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

A: The RCP2512W75R0GEB has tighter tolerance (±2%) compared to RCP2512W75R0JS3 (±5%), and RCP2512W75R0GEB is RoHS3 compliant while RCP2512W75R0JS3 is RoHS non-compliant. All other electrical and mechanical specifications are identical.

Q: Are the physical dimensions identical?

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

Q: Does tolerance difference affect circuit performance?

A: Tolerance affects the precision of the resistance value. RCP2512W75R0JS3 delivers 75 Ohms ±5% (71.25Ω to 78.75Ω range), while RCP2512W75R0GEB delivers 75 Ohms ±2% (74.6Ω to 76.5Ω range). Applications requiring tighter resistance control should use the ±2% part.

Q: What is the MSL rating and why does it matter?

A: Both parts have MSL 1 (Unlimited), indicating they are not moisture-sensitive and require no special handling or storage conditions. This simplifies inventory management and assembly processes.
