Key Parameters

Substitute Part Grouping Explanation

The RSF2JT9K10 qualifies as a direct substitute for the RSMF2JB9K10 based on the following matching electrical and mechanical parameters:

• Identical resistance value: 9.1 kOhms
• 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 RoHS compliance: ROHS3 Compliant
• Identical number of terminations: 2

The primary difference between these parts is the packaging format (Bulk versus Tape & Reel) and physical dimensions, with the substitute featuring a slightly larger body size. Both parts maintain equivalent electrical performance and safety certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the RSMF2JB9K10 and RSF2JT9K10 are active production parts with ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on:

• Packaging requirements: The RSMF2JB9K10 is supplied in Bulk packaging, while the RSF2JT9K10 is supplied in Tape & Reel format for automated assembly processes.
• Physical space constraints: The RSF2JT9K10 has larger body dimensions (0.217" diameter × 0.591" length) compared to the RSMF2JB9K10 (0.177" diameter × 0.433" length). PCB layout compatibility must be verified for the substitute part.
• Supply chain availability: The RSF2JT9K10 currently has higher inventory (1,088 units) compared to the RSMF2JB9K10 (751 units).

Both parts maintain identical electrical performance and safety certifications for direct substitution in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can RSF2JT9K10 be used as a direct replacement for RSMF2JB9K10?

A: Yes. Both parts share identical electrical specifications: 9.1 kOhms resistance, ±5% tolerance, 2W power rating, metal oxide film composition, and operating temperature range of -55°C to 235°C. Both are ROHS3 compliant and manufactured by Stackpole Electronics Inc.

Q: What are the physical differences between these parts?

A: The RSF2JT9K10 has larger body dimensions (0.217" diameter × 0.591" length) compared to the RSMF2JB9K10 (0.177" diameter × 0.433" length). PCB layout verification is required before substitution to ensure adequate clearance.

Q: Why are the packaging formats different?

A: The RSMF2JB9K10 is supplied in Bulk packaging for manual assembly or small-volume applications. The RSF2JT9K10 is supplied in Tape & Reel format, optimized for automated pick-and-place assembly processes in high-volume manufacturing.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS3 compliance, REACH unaffected status, and EAR99 ECCN classification. Both are classified under HTSUS code 8533.21.0090.

Q: What is the primary consideration for selecting between these substitutes?

A: The primary consideration is packaging format and physical dimensions. Verify that the larger body size of the RSF2JT9K10 is compatible with your PCB layout before implementation.
