Key Parameters

Substitute Part Grouping Explanation

Substitution of the RCP2512B680RJS6 is determined by strict equivalence in the following critical parameters:

• Resistance value: 680 Ohms (exact match required)
• Power rating: 4.6W (equal or greater acceptable)
• Package / Case: 2512 (6432 Metric) (exact match required for PCB compatibility)
• Composition: Thick Film (maintains thermal and electrical characteristics)
• Temperature coefficient: ±150ppm/°C (ensures frequency stability)
• Operating temperature range: -65°C ~ 155°C (functional envelope)
• Moisture resistance: Required feature
• Moisture Sensitivity Level: 1 (Unlimited)

The RCP2512W680RGEB qualifies as a direct substitute based on these parameters. The primary difference is improved tolerance specification (±2% versus ±5%), which represents an upgrade in precision without affecting circuit compatibility.

Parameter Comparison

Engineering Selection Recommendations

The RCP2512W680RGEB is a qualified substitute for the RCP2512B680RJS6 in applications where component specifications are compatible. Selection between these parts should be based on the following criteria:

RCP2512B680RJS6 is appropriate for applications with no RoHS compliance requirement and where ±5% tolerance meets circuit specifications.

RCP2512W680RGEB is appropriate for applications requiring ROHS3 compliance and where improved tolerance specification (±2%) provides circuit performance benefits. This part offers superior compliance status and tighter tolerance control while maintaining identical electrical and mechanical characteristics.

Both parts are actively produced and available in production quantities. The choice between them depends on regulatory requirements and tolerance specifications demanded by the end application.

Frequently Asked Questions (FAQ)

Q: Can RCP2512W680RGEB replace RCP2512B680RJS6 in existing designs?

A: Yes. Both parts share identical resistance value, power rating, package dimensions, and operating temperature range. The substitute offers improved tolerance (±2% versus ±5%) and ROHS3 compliance. No PCB layout or circuit modifications are required.

Q: What is the significance of the tolerance difference between ±5% and ±2%?

A: Tolerance defines the acceptable deviation from the nominal 680 Ohm resistance value. The ±5% part allows deviation from 646 to 714 Ohms. The ±2% part allows deviation from 666.4 to 693.6 Ohms. Applications requiring tighter resistance control benefit from the ±2% specification.

Q: Are both parts identical in physical dimensions?

A: Yes. Both parts use the 2512 (6432 Metric) package with identical dimensions: 0.250" L x 0.124" W (6.35mm x 3.15mm) and maximum seated height of 0.025" (0.64mm). They are mechanically interchangeable on PCBs designed for this package.

Q: What does ROHS3 compliance mean?

A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting specific hazardous materials in electrical and electronic equipment. The RCP2512B680RJS6 is RoHS non-compliant, while RCP2512W680RGEB is ROHS3 compliant.

Q: Do both parts have the same moisture sensitivity?

A: Yes. Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
