Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RSMF3JB20K0 are identified based on strict electrical and mechanical parameter matching. The substitution criteria are:

• Resistance value: 20 kOhms
• Tolerance: ±5%
• Power rating: 3W
• Composition: Metal Oxide Film
• Package type: Axial
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 235°C
• Physical dimensions: 0.217" Dia x 0.591" L (5.50mm x 15.00mm)
• Features: Flame Proof, Safety
• RoHS compliance: ROHS3 Compliant

The primary difference between the main part and its substitute is packaging format. The RSMF3JB20K0 is supplied in Bulk packaging, while the RSMF3JT20K0 is supplied in Cut Tape (CT) packaging. Both parts are manufactured by Stackpole Electronics Inc within the RSMF series and maintain identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the RSMF3JB20K0 and RSMF3JT20K0 are Active products from Stackpole Electronics Inc and maintain identical electrical and mechanical specifications. Selection between these parts is determined by procurement and assembly requirements:

The RSMF3JB20K0 in Bulk packaging is suitable for high-volume applications where components are supplied in loose form for automated or manual assembly processes. The RSMF3JT20K0 in Cut Tape (CT) packaging is appropriate for automated pick-and-place assembly systems that require tape-and-reel format delivery.

Both parts satisfy ROHS3 compliance and REACH unaffected status, confirming regulatory alignment for modern electronic applications. The identical electrical characteristics, temperature performance, and physical dimensions ensure functional interchangeability within circuit designs.

Frequently Asked Questions (FAQ)

Q: Can RSMF3JT20K0 be used as a direct replacement for RSMF3JB20K0?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format: Bulk versus Cut Tape (CT). Selection depends on assembly process requirements, not circuit performance.

Q: What determines substitution eligibility for the RSMF3JB20K0?

A: Substitute parts must match all electrical parameters (20 kOhms resistance, ±5% tolerance, 3W power rating, ±200ppm/°C temperature coefficient, -55°C to 235°C operating range), composition (Metal Oxide Film), package type (Axial), physical dimensions (0.217" Dia x 0.591" L), and features (Flame Proof, Safety).

Q: Are there differences in reliability or performance between Bulk and Cut Tape packaging?

A: No. Packaging format affects delivery and handling only. Electrical performance, reliability, and operating characteristics are identical between RSMF3JB20K0 and RSMF3JT20K0.

Q: Do both parts meet current compliance requirements?

A: Yes. Both RSMF3JB20K0 and RSMF3JT20K0 are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic components.

Q: What is the significance of the RSMF series designation?

A: The RSMF series identifies these components as Stackpole Electronics Inc metal oxide film axial resistors with consistent electrical and mechanical specifications across the product line.
