Substitute Part Grouping Explanation

The RSMF2JB56R0 and RSMF2JT56R0 are direct electrical and mechanical equivalents within the Stackpole RSMF series. Substitution is valid based on the following criteria:

• Identical resistance value: 56 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 x 0.433" L (4.50mm x 11.00mm)
• Identical features: Flame Proof, Safety
• Identical compliance: ROHS3 Compliant, REACH Unaffected

The only difference between these parts is the packaging format: RSMF2JB56R0 is supplied in bulk packaging, while RSMF2JT56R0 is supplied in cut tape (CT) format. Both parts are manufactured by Stackpole Electronics Inc and maintain active product status.

Parameter Comparison

Engineering Selection Recommendations

Both RSMF2JB56R0 and RSMF2JT56R0 are suitable for direct substitution in applications requiring a 56 Ohms 2W axial metal oxide film resistor. Selection between these parts should be based on procurement and assembly requirements:

RSMF2JB56R0 in bulk packaging is appropriate for high-volume manual assembly operations or when component storage in bulk format aligns with inventory management practices.

RSMF2JT56R0 in cut tape format is appropriate for automated pick-and-place assembly systems and tape-fed component handling equipment.

Both parts maintain identical electrical performance, thermal characteristics, and regulatory compliance (ROHS3 Compliant, REACH Unaffected). The choice between these variants does not affect circuit performance or reliability.

Frequently Asked Questions (FAQ)

Q: Can RSMF2JT56R0 replace RSMF2JB56R0 in my circuit design?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (cut tape versus bulk). Circuit performance and reliability are unaffected by this substitution.

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

A: Bulk packaging supplies loose components suitable for manual assembly. Cut tape packaging supplies components on continuous tape with carrier, designed for automated pick-and-place assembly equipment. Electrical specifications are identical.

Q: Are there any compliance differences between these parts?

A: No. Both RSMF2JB56R0 and RSMF2JT56R0 are ROHS3 Compliant and REACH Unaffected. Regulatory status is identical.

Q: What are the key parameters that define substitution eligibility?

A: Resistance value (56 Ohms), tolerance (±5%), power rating (2W), composition (Metal Oxide Film), temperature coefficient (±200ppm/°C), operating temperature range (-55°C to 235°C), and physical dimensions (0.177" Dia x 0.433" L) must remain constant for valid substitution.

Q: Can I use these parts in high-temperature applications?

A: Yes. Both parts are rated for operating temperatures up to 235°C, suitable for high-temperature circuit applications within this specification.
