Key Parameters

Substitute Part Grouping Explanation

The RSMF3JB56R0 and RSMF3JT56R0 are direct substitutes based on identical electrical and mechanical parameters. Both parts share the same resistance value (56 Ohms), tolerance (±5%), power rating (3W), composition (metal oxide film), temperature coefficient (±200ppm/°C), operating temperature range (-55°C to 235°C), physical dimensions (0.217" Dia x 0.591" L), and axial package configuration. The substitution is valid across all electrical performance criteria. The primary difference is packaging format: RSMF3JB56R0 is supplied in bulk packaging, while RSMF3JT56R0 is supplied in cut tape format. Both maintain identical compliance certifications (ROHS3, REACH unaffected, EAR99 ECCN classification).

Parameter Comparison

Engineering Selection Recommendations

Both RSMF3JB56R0 and RSMF3JT56R0 are active production parts with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on procurement and assembly requirements. The bulk packaging format (RSMF3JB56R0) is suitable for high-volume applications or manual assembly processes. The cut tape format (RSMF3JT56R0) is optimized for automated pick-and-place assembly systems. Both parts maintain identical electrical performance and thermal characteristics across the full operating temperature range of -55°C to 235°C. Inventory availability should be evaluated based on project timeline requirements.

Frequently Asked Questions (FAQ)

Q: Can RSMF3JT56R0 be used as a direct replacement for RSMF3JB56R0? A: Yes. Both parts are electrically and mechanically identical with matching resistance (56 Ohms), tolerance (±5%), power rating (3W), temperature coefficient (±200ppm/°C), and operating temperature range (-55°C to 235°C). The only difference is packaging format.

Q: What is the difference between bulk and cut tape packaging? A: Bulk packaging (RSMF3JB56R0) supplies components loose in a container, suitable for manual handling and assembly. Cut tape packaging (RSMF3JT56R0) supplies components on continuous tape, optimized for automated assembly equipment.

Q: Are both parts RoHS compliant? A: Yes. Both RSMF3JB56R0 and RSMF3JT56R0 are ROHS3 compliant and REACH unaffected.

Q: Do these parts have identical physical dimensions? A: Yes. Both parts measure 0.217" diameter by 0.591" length (5.50mm x 15.00mm) in axial configuration.

Q: What is the temperature coefficient specification? A: Both parts have a temperature coefficient of ±200ppm/°C, ensuring stable resistance performance across the operating temperature range of -55°C to 235°C.

Q: Are these flame-proof resistors? A: Yes. Both RSMF3JB56R0 and RSMF3JT56R0 feature flame-proof and safety characteristics as part of the metal oxide film construction.
