Substitute Part Grouping Explanation

The RSMF2JB75R0 and RSMF2JT75R0 are functionally equivalent resistors within the Stackpole RSMF series. Substitution is valid based on the following criteria:

• Identical resistance value: 75 Ohms
• Identical tolerance: ±5%
• Identical power rating: 2W
• Identical composition: Metal Oxide Film
• Identical package type: Axial
• Identical temperature coefficient: ±200ppm/°C
• Identical operating temperature range: -55°C to 235°C
• Identical physical dimensions: 0.177" Dia × 0.433" L (4.50mm × 11.00mm)
• Identical compliance certifications: ROHS3, REACH Unaffected, EAR99

The primary difference between these parts is packaging format: RSMF2JB75R0 is supplied in bulk packaging, while RSMF2JT75R0 is supplied in cut tape format. Both parts maintain identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both RSMF2JB75R0 and RSMF2JT75R0 are active production parts with identical electrical and mechanical specifications. Selection between these parts should be based on packaging requirements and inventory availability. The RSMF2JT75R0 in cut tape format offers higher current inventory (6178 units) compared to the bulk-packaged RSMF2JB75R0 (1070 units). Both parts maintain full ROHS3 compliance and REACH compliance status, making them suitable for applications with regulatory requirements. The identical physical dimensions and thermal characteristics ensure direct functional interchangeability in circuit designs.

Frequently Asked Questions (FAQ)

Q: Can RSMF2JT75R0 be used as a direct replacement for RSMF2JB75R0?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format: bulk versus cut tape. They share identical resistance, tolerance, power rating, temperature range, and physical dimensions.

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

A: Bulk packaging (RSMF2JB75R0) supplies components in loose form, suitable for manual assembly or bulk handling. Cut tape packaging (RSMF2JT75R0) supplies components on continuous tape, optimized for automated pick-and-place assembly equipment.

Q: Are both parts RoHS compliant?

A: Yes. Both RSMF2JB75R0 and RSMF2JT75R0 are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for restricted substances.

Q: Do these resistors have identical thermal performance?

A: Yes. Both parts have identical temperature coefficients (±200ppm/°C) and operating temperature ranges (-55°C to 235°C), ensuring equivalent thermal stability in circuit applications.

Q: Which part should be selected for automated assembly?

A: RSMF2JT75R0 in cut tape format is designed for automated pick-and-place assembly. RSMF2JB75R0 in bulk format is suitable for manual assembly or applications where tape packaging is not required.
