Key Parameters

Substitute Part Grouping Explanation

The RSF2JB30R0 and RSF2JT30R0 are direct electrical and mechanical equivalents within the Stackpole RSF series. Substitution is valid based on the following criteria:

• Identical resistance value: 30 Ohms
• Identical tolerance: ±5%
• Identical power rating: 2W
• Identical composition: Metal Oxide Film
• Identical temperature coefficient: ±200ppm/°C
• Identical operating temperature range: -55°C to 235°C
• Identical package type: Axial
• Identical physical dimensions: 0.217" Dia × 0.591" L (5.50mm × 15.00mm)
• Identical number of terminations: 2
• Identical compliance certifications: ROHS3, REACH Unaffected, EAR99

The primary difference between these parts is packaging format: RSF2JB30R0 is supplied in bulk packaging, while RSF2JT30R0 is supplied in cut tape (CT) format. Both parts maintain identical electrical performance and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both RSF2JB30R0 and RSF2JT30R0 are qualified for direct substitution in applications requiring 30 Ohm, 2W axial resistors. Selection between these parts should be based on procurement and assembly requirements:

RSF2JB30R0 (Bulk packaging) is suitable for manual assembly, rework operations, and applications where component handling flexibility is prioritized.

RSF2JT30R0 (Cut Tape packaging) is optimized for automated pick-and-place assembly processes and high-volume production environments.

Both parts maintain full compliance with ROHS3 and REACH regulations. The identical electrical specifications, temperature characteristics, and physical dimensions ensure seamless interchangeability in circuit designs without performance degradation or layout modifications.

Frequently Asked Questions (FAQ)

Q: Can RSF2JT30R0 replace RSF2JB30R0 in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (cut tape versus bulk). No circuit modifications or PCB layout changes are required.

Q: What is the difference between bulk and cut tape packaging?

A: Bulk packaging (RSF2JB30R0) supplies components loose in a container, suitable for manual handling and small-batch assembly. Cut tape packaging (RSF2JT30R0) supplies components on continuous tape, optimized for automated assembly equipment.

Q: Are both parts RoHS compliant?

A: Yes. Both RSF2JB30R0 and RSF2JT30R0 are ROHS3 compliant and REACH unaffected.

Q: Do these parts have identical temperature performance?

A: Yes. Both parts operate across -55°C to 235°C with identical temperature coefficient of ±200ppm/°C.

Q: Can these parts be used interchangeably in high-reliability applications?

A: Yes. Both parts are manufactured by Stackpole Electronics Inc with identical specifications, composition, and compliance certifications. Interchangeability is valid for all applications within the specified operating parameters.
