Key Parameters

Substitute Part Grouping Explanation

The RSMF2JB510R has one identified substitute: RSMF2JT510R. Both parts are manufactured by Stackpole Electronics Inc within the RSMF series and share identical electrical and mechanical specifications. The substitution is valid based on the following matching parameters:

• Resistance value: 510 Ohms
• Tolerance: ±5%
• Power rating: 2W
• Composition: Metal Oxide Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 235°C
• Package type: Axial
• Physical dimensions: 0.177" Dia x 0.433" L (4.50mm x 11.00mm)
• RoHS compliance: ROHS3 Compliant

The primary difference between these parts is packaging format: RSMF2JB510R is supplied in bulk packaging, while RSMF2JT510R is supplied in cut tape (CT) format. This distinction affects inventory management and automated assembly processes but does not impact electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

Both RSMF2JB510R and RSMF2JT510R are active production parts from Stackpole Electronics Inc with identical electrical performance and compliance certifications. Selection between these parts should be based on assembly process requirements and inventory management practices:

RSMF2JB510R in bulk packaging is suitable for manual assembly, kit preparation, and applications where component organization by value is preferred. RSMF2JT510R in cut tape format is optimized for automated pick-and-place assembly systems and tape-fed component feeders. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for industrial and consumer applications.

Frequently Asked Questions (FAQ)

Q: Can RSMF2JT510R be used as a direct replacement for RSMF2JB510R in circuit design?

A: Yes. Both parts have identical electrical specifications, power ratings, temperature coefficients, and operating ranges. The circuit performance will be equivalent.

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

A: Bulk packaging supplies loose components suitable for manual handling and sorting. Cut tape packaging supplies components on continuous tape with carrier backing, designed for automated assembly equipment. The components themselves are identical.

Q: Are there any compatibility issues when switching between these two part numbers?

A: No compatibility issues exist from an electrical or mechanical standpoint. The only consideration is assembly process compatibility—bulk format requires manual feeding, while cut tape format requires tape-compatible feeders.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both RSMF2JB510R and RSMF2JT510R are ROHS3 compliant and REACH unaffected, meeting identical regulatory standards.

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

A: Yes. Both parts are rated for operating temperatures from -55°C to 235°C with a temperature coefficient of ±200ppm/°C, suitable for industrial and high-temperature environments.
